 public diagnostic codes; originals continue to relay and no app/config repair is automatic.
+Each completed check also publishes a `buildAssessment` record on runtime status holding only
+`assessedVersion`, `observedVersion`, `verified` and `completedAt`. A status read never starts
+a probe, a runtime without a real probe omits the field, and an aborted or in-flight check never
+replaces the last completed assessment, including across stop/start probe replacement and early
+routing failures. A newly completed failed probe supersedes that prior observation; retained
+metadata is diagnostic only and never authorizes a new start or Apply. `observedVersion` is reported only when the discovered
+package matches the assessed family, App entry and canonical basename, so a foreign or unidentifiable
+install reports `null` rather than raw discovery data, an identified newer build reports its own
+version with `verified` false, and a failed or missing read is unverified rather
+than a stale success. The allowlist stays pinned to one exact package version because the
+correction contract is verified per build, which is why a newer installed client is reported
+unverified instead of treated as covered.

 | Startup safety | `GET /api/startup-health` reports whether injected Codex routing is restart-safe, with secret-free service/shim diagnostics. `POST /api/startup-action` provides allowlisted one-click installation for the background service or launcher shim. On Windows a healthy script shim is CLI-only; Codex Desktop requires the background service for full protection. Optional Codex compatibility uses the [confirmed local runtime](clients/codex-desktop.md#optional-compatibility-runtime), [machine-local dashboard consent](clients/codex-desktop.md#dashboard-controls), and [revision-bound next-start preference with shared awaited teardown](clients/codex-desktop.md#proxy-startup-preference); saving that preference performs no runtime action. |
 | Windows tray | `GET/POST /api/windows-tray` controls an owned, per-user HKCU login tray. The tray delegates fixed actions to the CLI and is never a proxy supervisor or restart-protection signal. |
 | Updates | `GET /api/update/check`, `POST /api/update/run`, and `GET /api/update/status` own dashboard self-update state. A launched worker PID is persisted in `update-job.json`; dead PIDs recover immediately, while legacy active records without a PID recover only after ten minutes. Live PIDs remain exclusive regardless of record age. `GET /api/update/check` and `POST /api/update/run` await one per-channel asynchronous registry lookup and write successful results through to the package cache; run passes that result to the job starter. `GET /api/update/badge` only reads the cache and reports unknown after 40 hours, on missing cache, or on channel mismatch. The badge links to the update surface rather than gating other actions. `GET /api/update/badge?surface=desktop&session=<id>` projects only that process-local Tauri session; missing or expired state is unknown and never falls back to the package cache. `POST /api/update/desktop-snapshot` is a 1 KiB bounded display-state mutation with no install permission. It accepts the existing admin-token principal or a dedicated single-use, ten-second snapshot capability bound to nonce, method, path, PID, port and the SHA-256 digest of the exact body bytes; that capability cannot authorize another route. |
-| Providers | Create/update/delete ordinary provider configs and enrich registry metadata. A `POST /api/providers` overwrite of an existing name keeps the nine operator compatibility settings (`PROVIDER_COMPAT_CARRY_FIELDS` in `src/server/management/provider-overwrite-carry.ts`) and the stored key pool only while the destination (adapter, normalized base URL, auth mode when named) is unchanged. It keeps omitted `hideRawReasoning` on every overwrite of the same name, including destination moves, because it is a display policy; a submitted boolean wins. It never merges the rest of the old row. `PATCH` is a field mask and keeps every field it does not name; `hideRawReasoning` and `preserveResponsesReasoningContent` accept a boolean or `null` to clear them. Custom Responses provider forms expose the latter as a default-off plaintext replay switch; unrelated settings saves preserve omission and curated/OpenAI destinations keep their existing defaults. The reserved `openai` card exposes Pool(default)/Direct account mode; `openai-apikey` remains the separate API route. |

Custom Responses provider forms expose `preserveResponsesReasoningContent` as a default-off plaintext replay switch; unrelated settings saves preserve omission and curated/OpenAI destinations keep their existing defaults.

 | Models | Fetch routed model lists, disabled model visibility, and catalog-facing ids. New non-OAuth registration holds exposure until authoritative discovery; 20 or more distinct switch rows start OFF without disabling the provider. Pending rows cannot accept visibility changes. Ordinary model reads also apply the [new-arrival catalog contract](catalog.md#shared-catalog) before returning models. With a matching persisted configuration, discovery records the baseline, NEW badges, and automatic disables together; HTTP listing does not wait for a separate Codex sync. Inventory already drifted from disk uses a detached policy projection: arrivals remain disabled in management rows without changing live config or disk. |
 | OAuth | Login/status/logout for OAuth-backed providers, plus multiauth account management: `GET /api/oauth/accounts`, `PUT /api/oauth/accounts/active`, `PUT /api/oauth/accounts/alias`, `PUT /api/oauth/accounts/pause`, and `DELETE /api/oauth/accounts` list masked accounts per provider, switch the active one, edit its display-only alias, pause/resume a generic OAuth account, and remove one. Paused generic OAuth accounts are excluded from request selection, 429 failover, and proactive token refresh; pausing an active account selects the next usable account when available, and resuming an account restores an active selection if the current one remains paused. With no unpaused account, requests return 403 rather than a login error. Kiro account-list rows include the current automatic-selection projection and closed exclusion reason; an active singleton may still send. The login flow itself is `GET /api/oauth/providers`, `POST /api/oauth/login`, `POST /api/oauth/login/code`, `POST /api/oauth/login/cancel`, `POST /api/oauth/logout`, and `GET /api/oauth/status`; pool controls are `GET/PUT/PATCH /api/oauth/accounts/pool` and `POST /api/oauth/accounts/clear-cooldown`. Login accepts `addAccount: true` to force a fresh browser identity. Meta Muse login start and manual-code continuation require the server-resolved `gui-session` principal before credential acquisition or code submission (including reauth); see the [provider contract](providers-and-adapters.md). Device flows return a structured `deviceCode`; the GUI highlights and copies it before the user opens the verification page. |
 | Key providers | `GET /api/key-providers` exposes API-key provider presets for setup and dashboard flows, and `GET/POST/DELETE /api/keys` owns the proxy's own admission keys. Machine links live in `src/server/management/link-routes.ts`: dashboard sessions reach `GET /api/link/candidates`, `POST /api/link/probe`, `POST /api/link/confirm-host` and `POST /api/link/apply`, meaning a paired session or, on a standalone runtime, the current loopback-issued session on trusted loopback ingress; `POST /api/link/join` instead requires an operator-paired session because it durably redirects local client traffic, and also refuses a runtime that is not standalone (`409 standalone_required`) or not listening on its configured port (`409 join_port_mismatch`) before any SSH, then restarts this runtime as a client; `GET /api/link/status` reports `joinAvailable` and typed `joinDenied` causes only to GUI-session callers, distinguishing pairing, runtime-role and port refusals without changing the admin/CLI DTO, so the dashboard enables the Child role only when the join gates pass; `GET /api/link/status`, `POST /api/link/{id}/reconnect` and `DELETE /api/link/{id}` also accept the admin token on a trusted loopback ingress, and reconnect restarts a Home-initiated link's tunnel now; `POST /api/link/issue` accepts only that admin token. Tailscale-identity sessions are refused on every link route. See [Remote Link](remote-link.md). Multi-key pool per key-auth provider: `GET /api/providers/keys`, `POST /api/providers/keys`, `PUT /api/providers/keys/active`, `PUT /api/providers/keys/alias`, `DELETE /api/providers/keys` masked list, add (upsert + activate), switch, rename, and remove keys. `provider.apiKey` always mirrors the active pool entry so routing stays single-key. |

 Combo preflight allows the private search tool only while a search plan is active; client tool declaration checks and replay-unsafe heartbeat protection remain enforced.

+Translated Responses delivery enforces declared-name membership. Native passthrough computes
+`undeclaredToolGuardActive` in `passthrough-dispatch.ts` and applies it in `passthrough-delivery.ts` before continuation state.
+Chat and Anthropic retain their delivery behavior for absent, partial and hosted-only deferred catalogs.
+
+A current-turn explicit empty catalog restricts client output on managed native Chat and Messages,
+translated adapter and run-turn delivery, direct client encoders, and final hosted-search, image
+or video output. Calls outside current-turn declarations become `undeclared_tool_call` before
+client delivery or continuation state, without a successful terminal after refusal. Other current
+declarations remain usable; internal hosted-search, vision, image and advisor work stays unchanged.
+Native Messages includes inline system-message definitions, honors permanent removals and re-offered
+known definitions, and compares restored OAuth names. Hosted `server_tool_use` and `mcp_tool_use`
+input deltas are tracked separately from client-executed `tool_use` blocks.
+
+Ingress `clientDeclaredEmptyToolCatalog` (`src/server/chat-completions.ts`, `src/server/claude-messages.ts`)
+survives omission during translation. Preparation snapshots declarations after direct decoding, before hosted-tool rewrites.
+Direct Chat with `tools: []` and legacy functions reads their names from the bridge projection;
+empty and omitted catalogs need no extra projection. Explicit `tools: []` or empty `additional_tools`
+activates the restriction; replayed declarations neither activate it nor grant names. Delivery
+normalization uses those names; direct custom `exec` helpers use the bridge compiler. Refusals keep `undeclared_tool_call` in buffered envelopes and endpoint
+projections; Messages sees `api_error`, never `overloaded_error`. Caller-forward routes retain their
+exemption; `default.` normalization remains separate.

 HTTP ingress applies the [caller header contract](../data-planes/inbound-compat.md#http-caller-conversation-identity) before admission and dispatch. Optional Codex memory selection enters `src/server/responses/request-prepare.ts` for HTTP and WebSocket frames, as specified in [memory phase routing](responses-failover.md#memory-phase-routing); an unset phase keeps its existing route and starts no background work. Responses request preparation stabilizes incoming `<skills_instructions>` under `skills.catalog_refresh`: `per_session` (default) reuses the first received catalog for a conversation; `per_turn` leaves the supplied catalog unchanged. Other instruction sections and user/tool content remain untouched. Requests without a reliable conversation identity bypass snapshots; shared prompt-cache cohorts are not conversation identities. Only a body with exactly one catalog block across its instructions and developer/system content takes part; two or more pass through unchanged. A known snapshot is substituted before parsing, but a new catalog is stored only when preparation reaches its success return, so a request rejected by parsing or admission pins nothing. Without a named principal, snapshots are shared by conversation id only on a server that requires no data-plane auth. Snapshots are process-local, expire after four idle hours, and use bounded LRU retention; oversized blocks bypass caching. The dashboard's `src/codex/prompt-layers.ts` and `src/codex/prompt-text-probe.ts` continue observing current files for previews and do not own session snapshots.

-Responses-compatible streaming output. The routed provider name follows every adapter build, including retries and continuations; only `github-copilot` injects a configured `modelContextTiers` value as upstream `contextTier`, while unconfigured passthrough retains the caller field. For an opted-in key-auth provider, a hosted-search continuation stays bound to the API-key selection that served the first leg; the contract is the [hosted-search continuation binding](../providers-and-adapters.md#hosted-search-continuation-binding). The native passthrough undeclared-tool guard fails closed on the Responses inbound wire in SSE and buffered JSON before continuation state is stored; Chat and Anthropic inbounds defer to the caller's own registry except an explicit empty catalog, which stays deny-all. GitHub Copilot Auto admission rechecks the negotiated provider/model against the key scope captured at request admission (a key edited or removed mid-request cannot widen it) before route mutation or dispatch, on initial and renewal negotiation; denial returns the standard `model_not_allowed_for_key` 403 naming the caller's inbound selector without disclosing the destination. The web-search and image sidecars answer a denial during their credential rotation with that 403 instead of the original 429, and a combo child's denial keeps the same envelope. Local model-scope refusals are non-replayable. A denial during Copilot dispatch renewal propagates as an admission exception to the request boundary, never as a provider fetch response; account recovery and combo/policy fallback cannot continue after that denial. A committed continuation, including OAuth account rotation after a 429, emits the same refusal type in-stream without dispatching another inference; ordinary negotiation failures still preserve the original provider refusal.

+On the dashboard **Advisor** page, choose the expert model from the catalog selector. It saves the exact catalog identifier, including native, provider, account-qualified, custom and combo selectors. Disabled models and models awaiting initial selection are not offered as new choices. A saved identifier missing from the selectable catalog remains visible with a warning and is preserved until you choose another model or clear it. Catalog loading failures preserve the selection and provide Retry. Choose a model that can return text advice: the catalog does not guarantee consultation compatibility.

+`gui/src/components/AdvisorModelSelect.tsx` loads `/api/models` independently of the settings editor and uses the shared `Select`. Values are exact `namespaced` routing selectors, never display names or lowercased input. Disabled and initial-selection-pending rows are excluded from new choices. A current value outside the selectable catalog remains visible with a warning; load failures preserve it and expose retry. Clearing saves the existing empty-model state. The catalog provides no text-consultation eligibility guarantee; the operator chooses a text-capable model. API and CLI model-string validation remains unchanged.

Subject: [PATCH 07/72] fix(usage): keep usage-ledger file ids exact so Windows
 NTFS ids stop colliding (#7089)

* fix(usage): keep usage-ledger file ids exact so Windows NTFS ids stop colliding

UsageLogRevision carried dev and ino as JS Numbers. NTFS file ids put a
sequence number in their high bits and routinely exceed 2^53, so two
different ledger files could round to the same Number and pass every
identity check: the history indexer, the ingest tail guard, the cooperative
ledger scanner and ledger retention would all treat a replaced ledger as the
recorded one. This is what made the stale-ledger build case fail on Windows
CI (#7070).

Read dev/ino through bigint fstat (exactFileIdentity) and carry them as
exact decimal strings end to end, including the schema_meta source identity,
following the Aside profile precedent in #3842. Indexes written by an older
build stored rounded values and rebuild once on mismatch.

The stale-ledger test goes back to perturbing ino, now exactly, and asserts
the revision matches bigint stats.

* docs(usage): describe exact ledger file identity and index rebuilds

* test(usage): cover colliding NTFS ids and legacy metadata reuse

 request-history index so no surface serves rows the ledger no longer has. That index (`src/routing/history/`) rebuilds a ledger of at least `REQUEST_HISTORY_WORKER_REBUILD_MIN_BYTES` (1 MiB) on a worker thread (#6990): `rebuild-worker.ts`, driven by `rebuild-job.ts`, ingests the ledger snapshot the refresh recorded into a private `<index>.rebuild-<pid>-<n>` file through the same `ingest.ts` the inline path uses, switches it to WAL and closes it; the serving thread then closes the old index and renames the build over it. Async readers wait for the build; the routing-time sync entry never does and throws `RequestHistoryIndexBusyError`, which health scoring reads as unknown evidence. A close discards the build, rejects waiting readers with `RequestHistoryIndexClosedError`, and removes the build files only after the worker thread exits. For 30 s after a worker build fails (other than on a replaced ledger), async readers and manual rebuilds rebuild inline instead, while routing-time reads keep reporting busy.

+Ledger revisions in `src/usage/log.ts` capture device/inode identifiers from bigint descriptor stats as exact decimal strings; history metadata, ingestion, cooperative scans and retention compare them without narrowing to Numbers, preserving distinct NTFS identifiers above 2^53. An older index containing a rounded identifier fails the identity check and rebuilds once. `src/usage/summary.ts` turns that file into the `/api/usage` shape — totals, daily zero-filled
 grid, model and provider breakdowns, and `measured / reported / unreported / unsupported / estimated` counts. Each scope also aggregates end-to-end output throughput (#6309): measured output tokens and wall-clock `durationMs` are summed over attempts reporting both, exposing `throughputTokensPerSec` — a token-sum-over-duration-sum, never a mean of per-request rates. `throughputSamples` counts qualifying attempts (legacy rows without attempts contribute one); nonpositive or nonfinite tokens/timing are excluded. The Usage summary and Models/Providers tables display the rate and sample basis, or unavailable when none qualify.
 All three throughput displays use the same finite-number guard as their tooltip; malformed or nonfinite rates are unavailable rather than formatted.

Subject: [PATCH 08/72] fix(desktop): serialize shim publication with
 production process creation (ETXTBSY) (#7106)

* fix(desktop): close atomic writer before publishing CLI files

* test(desktop): exclude executable writers from concurrent forks

Share a Unix test read/write lock between executable fixture writes and every synchronous subprocess spawn. Close-on-exec does not prevent a forked child from temporarily retaining a writer, which made direct shim execution return ETXTBSY during the CLI record lock stress test. Keep non-executable record writes and all four stress spawners concurrent, and assert that executable writes wait until spawn protection ends.

* test(desktop): tolerate a poisoned executable-IO lock so one panic cannot cascade

* test(desktop): isolate command deadlines from fixture spawn contention

* fix(desktop): coordinate executable publication with production forks

+Atomic replacement flushes and closes its write handle before publishing the new file by rename,

+guard through exec, so no child inherits the writable executable descriptor. Closing only the parent's
+close-on-exec descriptor would leave a forked duplicate writable until that child's exec.
+The same guard covers runtime start (`sidecar.rs`), resolve, claim and stop output futures, macOS
+launchctl/plutil probes (`login_registration.rs`), browser and Login Items launchers, updater install
+helpers and app restart. Shell-plugin output futures take the guard while being polled, including the

Subject: [PATCH 09/72] fix(claude): verify Desktop backup and optional
 metadata reads (carry #7084) (#7129)

* fix(claude): verify Desktop backup and optional metadata reads

* fix(claude): back up and roll back Desktop profiles from one verified read

The gateway writer read the profile for foreign-key preservation, reread it
for the backup, and reread the backup for rollback. A .bak swapped between
replacement and rollback made rollback refuse, leaving the new profile beside
the old metadata. One verified snapshot now feeds all three, rollback restores
those bytes, and a profile created by the failed apply is removed so retries
cannot accumulate unreferenced profiles.

* fix(claude): refuse stale Desktop snapshots and retain rollback errors

Revalidate verified profile bytes before backup and in the no-follow publication hook, refusing drift without retries. Keep metadata publication errors primary when profile restoration or cleanup also fails, and report both failures. Cover concurrent edits and rollback failures with regression tests.

* fix(claude): roll back a Desktop profile only while it still holds our bytes

When metadata publication fails, restore or cleanup now re-reads the profile through the verified reader and acts only if it still equals the bytes this apply published, using the same compare-and-swap helper that guards publication (also enforced before the restore rename). A profile another writer changed is preserved and the metadata error is reported with the rollback skipped.

+Optional metadata and profile reads treat only a missing directory entry as absent. Dangling links
+and other read failures refuse before profile publication. A gateway apply captures one profile
+snapshot (`readDesktopProfileSnapshot`); those verified bytes supply the preserved foreign keys,
+the `.bak` copy, and rollback. Before backup and again in the no-follow writer's pre-rename hook,
+the verified optional reader compares the live bytes with that snapshot (including absence).
+Drift refuses with `desktop_profile_changed`, without retrying; a non-regular entry still refuses
+without opening a FIFO or following a link. Drift detected before backup leaves the backup and
+metadata untouched; drift during temp staging leaves the concurrent live profile and metadata
+untouched. These are bounded optimistic checks, not a filesystem transaction with external writers.
+When metadata publication fails, rollback restores the captured bytes without reopening the
+backup; a profile the same apply created is removed instead. Rollback is ownership-aware: the same
+compare-and-swap helper (`assertDesktopProfileUnchanged`) checks that the live profile still holds
+the bytes this apply published, before acting and again before the restore rename. If another
+writer changed it, rollback is skipped, that profile is preserved, and the metadata error is
+reported with "profile rollback skipped". A failed rollback keeps the metadata error as the
+primary cause and reports that profile rollback also failed. An absent profile does not adopt a
+leftover backup from an earlier operation.

 the outstanding iterator read to replay once, while callers without a bound keep the existing wait.

Qoder supplies its vendor semantics from `src/adapters/qoder/adapter.ts`, including PAT rejection and account quota exhaustion. Numeric `error_code` values are authoritative: 105 permits PAT-rejection recovery, 110/118 permit account-quota recovery, 114 is a terminal permission refusal, and the other supported quota codes do not grant recovery. Unknown numeric codes retain the original error without text fallback. With no numeric code, quota recovery requires the supported account-daily prefix and no team/model/shared qualifier; generic credit-limit text grants none. Exit classification cannot replace an earlier terminal or protocol failure. The internal error event's `apiKeyRecovery: true` permits consideration, not execution, of key recovery and is never serialized. Only Qoder's private classifier grants recovery permission. Without a classifier, CodeBuddy and Claude CLI retain their original normalized events without permission; neither `tokenEnv` nor the unchanged shared parser's status or legacy quota classification grants it.

+# OAuth Preset Reconciliation
+
+`src/oauth/index.ts` refreshes registry-owned model rosters and capability lists at startup
+and OAuth upsert. Saved `contextWindow` and `defaultMaxOutputTokens` are operator limits;
+presets fill them only when absent. Saved `modelContextWindows`, `modelMaxOutputTokens`,
+`modelInputModalities` and effort translation maps override preset
+entries, with missing keys filled from the preset. Model keys match case-insensitively;
+array values, including `[]`, replace the seeded value. A saved per-model effort translation
+map is retained as one entry; request-time static policy fills missing inner aliases separately.
+Preset-owned reasoning ladders refresh seeded model rows; unseeded rows and provider tiers
+without preset defaults survive. `modelReasoningEffortsAuthoritative: true` explicitly makes
+saved model ladders operator-owned, so their entries win over preset tiers too.
+`modelContextTiers` and other operator policy remain outside catalog replacement. This keeps
+Copilot long-context evidence and xAI window overrides through restarts and re-login.
+Saved seeds have no provenance separate from operator edits, so existing entries are retained;
+only missing operator-map defaults refresh. Live discovery and request-time admission keep their own limits.
+Regression coverage: `tests/oauth/oauth-reconcile-operator-maps.test.ts`.

Subject: [PATCH 12/72] fix(cli): refuse uncertain ownership before publishing
 sibling runtime (#7142)

* fix(cli): refuse uncertain ownership before publishing sibling runtime

Carries #7119 (commit c5e17b50b2c3508d023c0ec560c7a1e2ca128812).

Co-authored-by: fwkyle <cv271010@gmail.com>

* fix(cli): isolate default-home owner discovery under test home guard

Co-authored-by: fwkyle <cv271010@gmail.com>

* fix(test): isolate owner registry under the armed home guard

Resolve the guarded registry beneath the selected config home when its override is absent. Pin the sandbox registry for inherited children and reject protected paths for reads and retirement as well as publication.

+Startup catalog sync and native restore apply the [retired-native policy](catalog.md#shared-catalog). Guarded tests isolate the owner registry used by cross-home discovery beneath their selected home, including children without a registry override; production retains the shared locator. See [test state isolation](ops/test-sandbox-cleanup.md).
 `src/server/background-lifecycle.ts` registers low-quota protection for each live server, flushes pending saves before releasing its owner, binds its own event ledger to management requests, and unregisters it on failed startup or stop; with no pending save, owner release remains synchronous. The protection writer loads config persistence only when a threshold schedules a save; see [configuration](config.md#codex-pool-low-quota-protection). Codex quota processing has shared and Reserve scopes; retired model evidence is suppressed as
 described in [OpenAI quota ownership](providers/openai-tiers.md#public-provider-contract).

Normal shutdown restores native Codex; a sibling instance beside a live proxy ([Codex home](codex-home.md#codex-home)) syncs and restores nothing, and `ocx stop` of a runtime whose record carries `siblingOfPort` skips the shared teardown. `src/cli/index.ts` resolves same-home ownership, then checks shared client hints through the cross-home owner helper, then reconciles the journal only when no sibling is marked. An indeterminate cross-home result refuses a new start before binding or publication, rather than persisting an unverified sibling topology; the next start performs fresh discovery. Service mode sets
 `OCX_SERVICE=1`, so managed restarts do not repeatedly restore/reinject; explicit service stop and
 uninstall still restore. `src/service/cli.ts` removes the service token on uninstall only when persisted client state is disconnected and no pending connect marker owns the newly issued key. `src/client/connect.ts` publishes that fingerprint marker before the key, then clears it with the connection commit or rollback under the client lifecycle and config mutation locks. Connected, invalid, or mismatched client state retains an existing token. A valid pending marker retains only its matching fingerprint; an older marker does not own a replacement service key. An absent token is reported as absent; unsafe, malformed, or unreadable markers and lock, state-read, or deletion failures leave cleanup unverified.
 `src/cli/tray-proxy.ts` coordinates `ocx restart` and tray restart. A second start requires proof the prior attempt never launched or its child exited, plus confirmed absence under a fresh bounded discovery window; a missing health response alone is insufficient. After an accepted restart, polling continues through uncertain observations until its deadline and requires a new runtime PID on the same port. If the old proxy then disappears, explicit recovery starts it regardless of the Codex autostart preference; a skipped recovery fails rather than reporting success. The Windows tray startup-health probe in `src/tray/windows-tray.ps1` requests termination at its 30-second deadline without waiting on the UI thread. It retains the process through later ticks until actual exit and both redirected readers settle; replacements cannot start while that reference is held. Launch setup failures follow the same cleanup. Tray shutdown alone waits at most 500 ms before disposal.

Subject: [PATCH 13/72] feat(codex): route hard-locked main-account traffic to
 a configured fallback model (carry #7123) (#7146)

* feat(codex): route hard-locked main-account traffic to a configured fallback model

The main-account hard lock (#5694) refuses requests once the 5h window reads
its 90% threshold or the weekly window reads 98%, and a monthly-only account
governs on monthly. On a single-account setup that refusal is the whole
session: Codex Desktop and CLI turns fail until the window resets even though
another provider in the same config could serve the turn.

Add extended settings to the same feature: codexMainAccountHardLockFallback
names a model and an optional reasoning effort, and while the lock blocks, a
qualifying request is rewritten to that selector instead of failing. The
rewrite is bounded on every side so it never widens what the lock protects:

- It fires only while the lock reads blocked; release stays the same fresh
  observation that admits, so the reroute ends with the lock, on its own.
- getEligiblePoolAccounts is the dispatch's own eligibility choke point, so a
  usable Pool account keeps the request on Codex; an empty eligible list is
  what makes the fallback the only way through.
- Only bare Codex-native selectors qualify. Provider-qualified rows, combos,
  account namespaces, policy routes and thread spawns name their own
  destination on purpose; Luna Reserve keeps its own admission.
- A Codex-native fallback target never applies -- rerouting gpt-* to gpt-*
  would re-enter the same refusal, so the honest behavior is the refusal.
- A malformed section disables the reroute entirely, the same
  disable-don't-widen reading the compaction override takes.

The management API projects the section in GET /api/settings, validates PUTs
against a strict schema before mutation, and null clears it. The dashboard's
main-account protection card grows the model and effort fields with the same
acknowledged-write contract as the toggle. The usage log keeps reporting the
selector the client asked for.

* fix(codex): harden main-account hard-lock fallback routing and credential boundaries

Pass the model's quota scope and respect Direct account mode when consulting getEligiblePoolAccounts so a pool account in a shared reset-derived cooldown or an unused pool under Direct mode cannot suppress the hard-lock fallback. Exclude nativeAlias combo selectors from source rewriting, reject canonical openai/<native> fallback targets alongside bare native ids, yield to non-combo shadow-call targets and compaction_trigger turns, mark credential-domain rewrites so caller ChatGPT headers and native reasoning ciphertext are stripped on fallback routes, preserve requestedModel and lane combo recall when routing to a fallback combo, include codexMainAccountHardLockFallback in Desktop compatibility routing preflight, and re-enable paused GUI fallback settings when picking a model.

* fix(codex): register main-hard-lock-routing in core inventory and lazy-load fallback models

Register main-hard-lock-routing.ts in RESPONSES_CORE_MODULES so the Responses core owner boundary suite includes it, and lazy-load /api/models in MainAccountHardLockSetting on fallback-control interaction so mounting the protection setting does not issue an unrequested background catalog fetch.

 | `codexProviderDisplayName?` | `string` | `"OpenCodex Proxy"` | Label Codex shows for the injected `opencodex` provider, written as its `name` field in `config.toml` and the reference profile. Presentation only: routing resolves through the provider id `opencodex`, so a rename never moves `model_provider = "opencodex"` or the `[model_providers.opencodex]` header and cannot orphan threads already tagged with that id. Codex refuses to load a provider with no name, so there is no way to omit the field — choose a neutral label instead. A blank, over-128-character, or control-character value is ignored and the default label is written. |
 | `codexMainAccountHardLock?` | `boolean` | `true` | Block new identity-matched main-account requests at their per-window threshold. Only explicit `false` opts out. See [main-account protection](/reference/cli/providers-accounts/#main-account-quota-protection). |
 | `codexMainAccountHardLockThresholds?` | `{ short?: number; long?: number }` | `{ short: 90, long: 98 }` | Independent 5h and weekly/monthly thresholds. Integers 80–100, with `short <= long`. Invalid persisted fields fall back to defaults; the settings API rejects invalid writes before mutation. |
+| `codexMainAccountHardLockFallback?` | `{ enabled?: boolean; model?: string; reasoningEffort?: string }` | off | Extended hard-lock settings: while the lock blocks and no Codex account can serve the request, qualifying native-Codex-model requests reroute to `model` with `reasoningEffort` instead of failing. `enabled: false` pauses the reroute and keeps the model. An absent section or model keeps the refusal behavior; a usable Pool account still serves first. `reasoningEffort` must be a declared effort; invalid persisted sections degrade to off and the settings API rejects invalid writes before mutation. See [main-account protection](/reference/cli/providers-accounts/#main-account-quota-protection). |
 | `nativeMainRefresh?` | `"codex" \| "opencodex"` | auto | Who refreshes the native main ChatGPT login in `CODEX_HOME`. `"codex"` asks the Codex binary (app-server `getAuthStatus`, Codex 0.130.0 or newer, found through the same runtime resolution as `ocx sync`, including the ChatGPT app bundle) and never writes `auth.json`; this also works when Codex stores its login in the OS keyring. `"opencodex"` keeps OpenCodex's guarded `auth.json` writer. Unset picks `"codex"` when a supported binary is found; without one, both unset and `"codex"` fall back to the guarded writer. `ocx doctor` shows the active mode under Native main refresh. |
 | `resetCreditAutoRedeem?` | `{ enabled?: boolean; leadTimeMinutes?: number }` | off | Opt-in: redeem the main Codex account's soonest-expiring reset credit `leadTimeMinutes` (1–60, default 10) before it expires. Every attempt re-reads the upstream credit list first and skips when the credit is gone (for example, redeemed by hand); the `redeem_request_id` is journaled in `$OPENCODEX_HOME/reset-credit-auto-redeem.json` before the call so a crash replays the same idempotent request instead of spending a second credit. Servers sharing this configuration directory coordinate reservations and settlements so one process does not replace another's request record. Logs carry a hashed account key only. |
 | `syncResumeHistory?` | `boolean` | `true` | Reversible Codex App history compatibility. Original metadata is backed up and restored by `ocx stop` / `ocx restore`. |

+## Hard-lock fallback routing
+
+`codexMainAccountHardLockFallback` extends the main-account hard lock: while the lock reads
+`blocked` and no Codex account can serve a request, `src/server/responses/main-hard-lock-routing.ts`
+rewrites that request to the configured model (plus an optional reasoning effort) before combo
+dispatch reads `model`. The rewrite is bounded on every side so it can never widen what the lock
+protects:
+
+- `getEligiblePoolAccounts` is consulted under the request model's quota scope whenever canonical
+  `openai` is in Pool mode, so "the Pool can serve it" shares the dispatch's own eligibility and
+  scoped-cooldown rules. An empty eligible list (or Direct mode, which never consults stored Pool
+  accounts) is what makes the fallback the request's only way through; the lock excludes the main
+  account there itself.
+- Only bare Codex-native selectors qualify. Provider-qualified rows, combos, account namespaces
+  (including `nativeAlias` combos), compaction triggers, shadow-intercepted helper calls and policy
+  routes name their own destination on purpose, and Luna Reserve keeps its own admission. A
+  Codex-native fallback target (bare `gpt-*` or canonical `openai/gpt-*`) never applies — rerouting
+  to the same blocked route would re-enter the refusal, so the honest behavior is the refusal.
+- Rewritten turns mark a credential-domain rewrite, strip foreign reasoning ciphertext, preserve
+  the caller's inbound selector for API-key scope checks and `requestedModel` logging (including
+  combo fallback targets), and do not overwrite the session lane's remembered combo.
+- A malformed section (blank or padded model, undeclared effort) disables the reroute entirely —
+  the same disable-don't-widen reading as the compaction override — while the load and write
+  boundaries report the malformation. The lock's own refusal behavior is untouched either way.
+
+The dashboard row mirrors the shadow-call row: the model pick, the effort and the switch each
+save immediately, and the switch writes `enabled: false` — a remembered pause that keeps the
+model — rather than clearing it. Settings projection and writes live beside the hard-lock keys in
+`src/server/management/config-routes.ts`; `null` clears the section. Coverage:
+`tests/codex-integration/main-account-hard-lock-fallback-routing.test.ts` and the fallback cases in
+`tests/config/settings-main-account-hard-lock.test.ts` plus
+`gui/tests/main-account-hard-lock-setting.test.tsx`.
+
 ## Stored-account authentication policy
 
 Exact pool selectors also honor the credits-after-limit policy. `pool-credit-policy.ts` reads cached usage and configured plan metadata without credential I/O. Authentication checks before and after credential acquisition; provider overrides, materialization and recovery rechecks retain the live policy privately by context identity. `createCodexAuthDispatchGuard` rechecks live credit policy at HTTP and Responses WebSocket dispatch after pacing or retry backoff, alongside the independent Reserve guard. A policy refusal releases unused probes and never quarantines a valid credential. Coverage: `tests/codex-integration/codex-pool-credit-policy.test.ts`.

Subject: [PATCH 15/72] feat(cli): configure usage model table row limits
 (carry #6436) (#7156)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat(cli): configure human usage model row limits (carry #6436)

Port the usage --top idea from #6436 (bfcba56371a481a3c4ca0a96f6161811a2816d5b) onto the capability shards and model-search formatter. Preserve existing JSON, report totals and the default search view.

Co-authored-by: 정우철 <86232509+oocheol@users.noreply.github.com>

* fix(cli): report one bounded message for invalid usage --top

Every invalid --top value now reports '--top must be an integer between 1 and 1000' through the shared integer parser's optional max, instead of '>= 1' for low or non-numeric values and a separate range message for values above 1000.

 `src/cli/log-view-filter.ts` owns the additive logs-filter snapshot, separate from existing follow/event transport. It fetches only the fixed log endpoint with a scan limit of at most 2000, applies GUI-equivalent local selectors, then returns the newest matches in source order without deduplicating. Model/provider matching covers resolved/served/attempt identities; protocol and conversation matching reuse their actual owners. Speed bounds accept observed value-kind metrics only. The versioned JSON view separates loaded, matched and returned counts from configured scan/output limits; JSONL is rows only. Neither a match count nor a cursor claims historical completeness or resumable search. Invalid options fail before discovery; malformed windows never become empty success.
 
-`src/cli/usage-model-search.ts` applies optional substring search only after the existing usage target/scope acknowledgment. A copied model list sorts stably by total tokens, searches model/provider/resolvedModel and caps at 100. The report's other fields remain intact; explicit modelView metadata distinguishes a view miss from no usage. `src/cli/usage-report.ts` retains the legacy renderer when no view is supplied and renders up to the selected 100 rows when one is supplied. Search never becomes a server attribution query or widens connected-client/key scope.
+`src/cli/usage-model-search.ts` applies optional substring search only after the existing usage target/scope acknowledgment. A copied model list sorts stably by total tokens, searches model/provider/resolvedModel and caps at 100 by default. The report's other fields remain intact; explicit modelView metadata distinguishes a view miss from no usage. `src/cli/usage-report.ts` retains the legacy renderer when no view is supplied and renders the selected rows when one is supplied. `--top` accepts 1–1000 human model rows (default 10 without search, 100 with search), applies after search and is never sent to the API. JSON ignores `--top`, including the existing 100-row search view and its metadata. Search never becomes a server attribution query or widens connected-client/key scope.
 
 `src/cli/companion-usage.ts` reads settings and two usage ranges sequentially on a pinned management target through `src/cli/observe-stream.ts`. Its safe projection follows the saved model/provider filters and measured-totals rules in `gui/src/pages/tray-data.ts` without importing GUI runtime code. It retains unknown/incomplete metrics, valid server defaults with null update time, and explicit corrupt/fallback flags. Malformed settings stop before usage reads. Range failure retains the other observed range, labels unavailable data, and returns partial/nonzero; signal cancellation emits no late report. The observation owner supplies a separate 10-second fetch/body deadline after discovery and 32 MiB cap for each fixed GET, not a command-wide budget. Snapshot context supplies truthful retry wording without altering default follow behavior.

Subject: [PATCH 16/72] feat(antigravity): show canonical plan badge in account
 rows (carry #5932) (#7157)

Carry only the missing account-row badge and accessibility from #5932 at 9b6e14d359cebb1c3fdd016bcc11384c9b2b45bc; plan persistence and projection already landed in #6953.

 | Updates | `GET /api/update/check`, `POST /api/update/run`, and `GET /api/update/status` own dashboard self-update state. A launched worker PID is persisted in `update-job.json`; dead PIDs recover immediately, while legacy active records without a PID recover only after ten minutes. Live PIDs remain exclusive regardless of record age. `GET /api/update/check` and `POST /api/update/run` await one per-channel asynchronous registry lookup and write successful results through to the package cache; run passes that result to the job starter. `GET /api/update/badge` only reads the cache and reports unknown after 40 hours, on missing cache, or on channel mismatch. The badge links to the update surface rather than gating other actions. `GET /api/update/badge?surface=desktop&session=<id>` projects only that process-local Tauri session; missing or expired state is unknown and never falls back to the package cache. `POST /api/update/desktop-snapshot` is a 1 KiB bounded display-state mutation with no install permission. It accepts the existing admin-token principal or a dedicated single-use, ten-second snapshot capability bound to nonce, method, path, PID, port and the SHA-256 digest of the exact body bytes; that capability cannot authorize another route. |
 | Providers | Create/update/delete ordinary provider configs and enrich registry metadata. A `POST /api/providers` overwrite of an existing name keeps the nine operator compatibility settings (`PROVIDER_COMPAT_CARRY_FIELDS` in `src/server/management/provider-overwrite-carry.ts`) and the stored key pool only while the destination (adapter, normalized base URL, auth mode when named) is unchanged. It keeps omitted `hideRawReasoning` on every overwrite of the same name, including destination moves, because it is a display policy; a submitted boolean wins. An omitted `inferContextWindow` likewise keeps the latest live same-name state after asynchronous validation, including `false` or a concurrent clear; a submitted boolean wins. It never merges the rest of the old row. `PATCH` is a field mask and keeps every field it does not name; `hideRawReasoning`, `preserveResponsesReasoningContent` and `inferContextWindow` accept a boolean or `null` to clear them, rejecting other types. `GET /api/providers` exposes configured `inferContextWindow` as an optional boolean without substituting a default; its [custom-only, default-off inference policy](catalog-vendor-context.md) is unchanged. Custom Responses provider forms expose `preserveResponsesReasoningContent` as a default-off plaintext replay switch; unrelated settings saves preserve omission and curated/OpenAI destinations keep their existing defaults. The reserved `openai` card exposes Pool(default)/Direct account mode; `openai-apikey` remains the separate API route. |
 | Models | Fetch routed model lists, disabled model visibility, and catalog-facing ids. New non-OAuth registration holds exposure until authoritative discovery; 20 or more distinct switch rows start OFF without disabling the provider. Pending rows cannot accept visibility changes. Ordinary model reads also apply the [new-arrival catalog contract](catalog.md#shared-catalog) before returning models. With a matching persisted configuration, discovery records the baseline, NEW badges, and automatic disables together; HTTP listing does not wait for a separate Codex sync. Inventory already drifted from disk uses a detached policy projection: arrivals remain disabled in management rows without changing live config or disk. |
-| OAuth | Login/status/logout for OAuth-backed providers, plus multiauth account management: `GET /api/oauth/accounts`, `PUT /api/oauth/accounts/active`, `PUT /api/oauth/accounts/alias`, `PUT /api/oauth/accounts/pause`, and `DELETE /api/oauth/accounts` list masked accounts per provider, switch the active one, edit its display-only alias, pause/resume a generic OAuth account, and remove one. Paused generic OAuth accounts are excluded from request selection, 429 failover, and proactive token refresh; pausing an active account selects the next usable account when available, and resuming an account restores an active selection if the current one remains paused. With no unpaused account, requests return 403 rather than a login error. Kiro account-list rows include the current automatic-selection projection and closed exclusion reason; an active singleton may still send. The login flow itself is `GET /api/oauth/providers`, `POST /api/oauth/login`, `POST /api/oauth/login/code`, `POST /api/oauth/login/cancel`, `POST /api/oauth/logout`, and `GET /api/oauth/status`; pool controls are `GET/PUT/PATCH /api/oauth/accounts/pool` and `POST /api/oauth/accounts/clear-cooldown`. Login accepts `addAccount: true` to force a fresh browser identity. Meta Muse login start and manual-code continuation require the server-resolved `gui-session` principal before credential acquisition or code submission (including reauth); see the [provider contract](providers-and-adapters.md). Device flows return a structured `deviceCode`; the GUI highlights and copies it before the user opens the verification page. |

Google Antigravity account rows in `gui/src/components/provider-workspace/ProviderAuthPanel.tsx` display the account-summary `plan` as a badge and include it in the account button’s accessible name. The value is the canonical upstream tier ID (for example `free-tier` or `gemini-pro`), preserved literally across locales rather than inferred as a product name. Absent plans render no badge; pause and reauthentication controls keep their existing behavior. |
 | Key providers | `GET /api/key-providers` exposes API-key provider presets for setup and dashboard flows, and `GET/POST/DELETE /api/keys` owns the proxy's own admission keys. Machine links live in `src/server/management/link-routes.ts`: dashboard sessions reach `GET /api/link/candidates`, `POST /api/link/probe`, `POST /api/link/confirm-host` and `POST /api/link/apply`, meaning a paired session or, on a standalone runtime, the current loopback-issued session on trusted loopback ingress; `POST /api/link/join` instead requires an operator-paired session because it durably redirects local client traffic, and also refuses a runtime that is not standalone (`409 standalone_required`) or not listening on its configured port (`409 join_port_mismatch`) before any SSH, then restarts this runtime as a client; `GET /api/link/status` reports `joinAvailable` and typed `joinDenied` causes only to GUI-session callers, distinguishing pairing, runtime-role and port refusals without changing the admin/CLI DTO, so the dashboard enables the Child role only when the join gates pass; `GET /api/link/status`, `POST /api/link/{id}/reconnect` and `DELETE /api/link/{id}` also accept the admin token on a trusted loopback ingress, and reconnect restarts a Home-initiated link's tunnel now; `POST /api/link/issue` accepts only that admin token. Tailscale-identity sessions are refused on every link route. See [Remote Link](remote-link.md). Multi-key pool per key-auth provider: `GET /api/providers/keys`, `POST /api/providers/keys`, `PUT /api/providers/keys/active`, `PUT /api/providers/keys/alias`, `DELETE /api/providers/keys` masked list, add (upsert + activate), switch, rename, and remove keys. `provider.apiKey` always mirrors the active pool entry so routing stays single-key. |
 | OpenAI account mode | Report one OpenAI Codex card with Pool/Direct controls and one API-key card. Mode PATCH persists live without restart or catalog identity changes; Pool owns account/quota controls and Direct uses caller/main login only. Main-account DTOs report real credential presence and terminal `needsReauth` state instead of treating missing/invalid native auth as an unknown quota. Selection order has its own route: `PUT /api/codex-auth/accounts/priority` takes `{ id, priority }`, where `priority` is an integer -100..100 or `null` to restore the default, accepts `__main__`, 404s an unknown id, and echoes the stored value. Re-ordering never clears thread affinity, so the response carries no `appliesImmediately`, but it does release any pin — see [`openai-tiers.md`](providers/openai-tiers.md) for why. `PUT /api/codex-auth/active` with a null id releases one too, but that drops the operator's account selection along with it, so this route is the only operator-facing way to clear a pin while leaving the selected account in place. `GET /api/codex-auth/active` reports `pinned`, true only while the manually selected account is still the effective active one, plus `pinnedAccountId`, which names the pinned account whether or not it is the active one. Surfaces should render `pinnedAccountId`: under round-robin and fill-first the pin caps the tier ceiling at its own tier while the strategy cursor moves freely inside that tier, so `pinned` goes false on a sibling's turn even though the pin is still suppressing every higher tier — which is why the dashboard badges `pinnedAccountId` and the GUI controller tracks only the id. `pinned` answers the narrower question of whether routing is *currently* on the operator's choice; no surface in this repo asks it, and a new one almost certainly wants the id instead. |
 | Subagents | Read/write the featured `subagentModels` list capped at five ids. `GET/PUT /api/injection-model` manages the shared delegation model/effort selection, the independent OpenCodex guidance switch, and the default-off `syncCodexSubagentDefaults` opt-in for native Codex subagent defaults. When OpenCodex owns the active Codex routing, native `[agents]` defaults apply to newly created Codex tasks after sync/restart; external user-managed provider configs remain untouched. The defaults do not cause delegation and preserve existing user-owned defaults rather than overwriting them. PUT is partial-update: absent keys are unchanged, `null` clears, and non-object bodies are rejected with 400 before field validation. `syncCodexSubagentDefaults: true` requires a nonblank `model` and a supported Codex reasoning effort when effort is set; clearing `model` (null/empty) always clears effort and disables native-default sync even when the stored effort was invalid. |

 Empty grants are not the same as unavailable status. It never consumes a grant
 or resumes a pending spend. Consumption remains a human GUI operation.
 
+### Use remaining included quota
+
+To keep using a selected account past a proactive switching threshold or the main-account
+protection threshold, explicitly enable its remaining-quota preference:
+
+```bash
+ocx account use-remaining openai main on
+ocx account use openai main
+ocx account use-remaining openai main status --json
+ocx account use-remaining openai main off
+```
+
+Replace `main` with a unique pool-account ID or alias to target an added account.
+Enabling this disables proactive usage switching for that account. For the main login, it also
+moves both effective hard-lock thresholds to 100%, so a 95% reading can still admit a request.
+The preference persists across restarts until turned off; original threshold settings remain
+stored and resume applying when it is disabled. It does not select an account itself or override
+round-robin scheduling, manual/automatic pause, entitlement checks, reauthentication, or upstream
+cooldowns. Paid-credit permission remains a separate setting; enabling this never opts an account
+into credits or redeems a reset grant. The default-on main hard lock still refuses at 100%.
+
+`GET /api/codex-auth/accounts/use-remaining?id=<account-id>` reads the live policy.
+`PUT /api/codex-auth/accounts/use-remaining` accepts `{ id, useRemainingQuota: boolean }`.
+Both require the existing management authentication. This control is currently exposed through
+the CLI and API.

A weekly or monthly reading without a reset time does not hold the account; a 5-hour reading at 100% without a reset holds it only while that reading is still fresh. When no other account is available, automatic selection finds none rather than spending credits. An unlisted `__main__` is also refused, like a hard-lock refusal, when a request names it or carries its credential. Listing `__main__` does not lift the main-account hard lock (on by default at 98%), which still stops the main login first; turn the lock off to let the main account spend credits (a lock at 100% still stops it at 100%).

 Opted-in main-account credit renewal follows the [spendable credit contract](openai-tiers.md#spendable-codex-credits). An unpaused, non-quarantined main identity with an exhausted included window keeps discovering credits even when its evidence is missing or unavailable; fresh positive evidence waits until three minutes of age for renewal. Admission remains blocked until fresh spendable evidence arrives, with the consented credit refusal's Retry-After bounded to five minutes. The existing background sweep prepares a token before WHAM, rechecks eligibility, and uses a passive probe that neither sets nor clears needs-reauth, including after identity retries. Other probes keep their existing auth behavior. A non-passive caller joining renewal applies terminal-auth quarantine, or clears it on a successful explicit refresh, only while its credential and configuration fences remain current; shared evidence does not inherit the owner's passive intent.

Subject: [PATCH 18/72] feat(combos): require explicit consent for metered
 targets (carry #6839) (#7159)

* feat(combos): require explicit consent for metered targets (carry #6839)

Port the metered target and subscription-chain regression work from #6839 at 5428b42440d68c73b8c12e14329e9e32cf9ff32e onto current dev. Require configured-key opt-in for all callers, retain metadata on dashboard saves, and preserve structured runTurn failures. Keep the newer fresh-read quota recovery; omit the timer cap and unrelated effort/tier changes.

Co-authored-by: 001005HS <99410048+001005HS@users.noreply.github.com>

* fix(combos): refuse metered picks on collapsed combo routes without consent

A subagent model fallback that names a combo alias is resolved by the router into one
combo pick and dispatched outside the combo loop, so its metered-target filter never ran:
a caller without allowMeteredComboTargets reached the metered target once the
subscription target was cooling. captureInboundRoutePolicy, which every route on the
Responses path passes through, now refuses a metered collapsed pick without consent.

Docs state that a loopback bind reads no key, so metered targets need a keyed listener.

Co-authored-by: 001005HS <99410048+001005HS@users.noreply.github.com>

* test(responses): pin structured combo-child preflight limits

The carry now forwards a runTurn adapter's structured status, type and code at the combo
preflight boundary, so a Devin pre-output limit inside a combo child reaches the combo
loop as a 429 rate_limit_exceeded instead of a generic 502. #5890 pinned the 502 only to
keep its own non-combo change out of combo children; the pin now states the new contract,
still without a Retry-After header, which the combo loop owns.

* feat(combos): add explicit loopback metered consent

* fix(combos): keep runTurn child verdicts through combo failover

A runTurn combo child already classifies its pre-output failure with
adapterFailureFromEvent, but formatErrorResponse re-derived the type and code
from the status. insufficient_quota became rate_limit_exceeded, losing its
provider-wide cooldown and the client's quota verdict, and a 400
unsupported_input_modality became invalid_request_error, which now stopped
the combo where dev's flat 502 had hopped to the next target.

formatErrorResponse gains a classified option that keeps the caller's type and
code while its spend-ledger, cyber-policy and replay-refusal overrides still
win. Only the two combo-child blocks use it; consumeComboFailure re-applies
the client allowlist before anything reaches a caller. Combo failover treats
unsupported_input_modality as a target-local hop that cools nothing.

Docs: an earlier 429/402 quota refusal outranks a later 400/401/403 when a
metered-consent combo exhausts, and the modality hop is listed in every
locale's combo guide.

Co-authored-by: 001005HS <99410048+001005HS@users.noreply.github.com>

* fix(bridge): keep message-read verdicts over a classified child code

formatErrorResponse's classified mode let a runTurn child's generic code
replace a cyber_policy verdict classifyError read from the full message.
consumeComboFailure sees only the first 500 characters, so a refusal phrase
past that point became a 502 that hopped to another provider. Cyber-policy,
context-length and client-closed verdicts read from the message now outrank
the caller's code.

Co-authored-by: 001005HS <99410048+001005HS@users.noreply.github.com>

* fix(bridge): let a classified child code fill in only what the message leaves open

The previous guard pinned only cyber-policy, context and client-closed
verdicts, so a coding-agent CLI's "Account quota exhausted" reported as a
generic 502 upstream_error still lost its insufficient_quota verdict and
cooled one target instead of the provider. The caller's code now applies only
when classifying the message adds nothing to the status and type, so every
message-read verdict (quota, cyber policy, context overflow, catalog size)
outranks a generic adapter code. Cyber-policy and client-closed stay pinned.

* docs(structure): describe when a classified combo-child code applies

Co-authored-by: 001005HS <99410048+001005HS@users.noreply.github.com>

* fix(bridge): compare a classified child code against the status alone

An untyped adapter event reaches the formatter with a type
adapterFailureFromEvent already inferred from its message, so comparing
against an empty message with that same type hid the message's verdict: a
502 upstream_error ending in "Authentication failed." lost invalid_api_key
and cooled one target instead of the provider. The baseline now uses a
neutral type, so a type or message verdict outranks a generic adapter code.

+## Metered fallback consent
+
+Mark a pay-per-use combo target with `"metered": true` when it follows subscription targets. Omitted or false consent denies metered dispatch. Choose consent for your deployment:
+
+- **Local Claude Code or Codex:** on a loopback-only proxy, set `"allowMeteredTargets": true` on the combo, or run `ocx combo set <id> --allow-metered-targets on`. This explicitly permits local callers to use its marked targets. The default is false; `off` clears consent. Loopback authentication does not read API keys.
+- **Network or linked callers:** the caller's configured `apiKeys[]` entry must have `"allowMeteredComboTargets": true`. A proxy with a non-loopback listener ignores the combo flag, including on its secondary loopback listener. Linked callers also retain their configured-key consent requirement when the primary listener is loopback. The environment token never qualifies.
+
+Request headers cannot grant consent. Model/provider scopes still apply. This covers initial selection, failover and recovery across combo strategies, compaction, Messages, Chat Completions and WebSocket requests, and a subagent model fallback naming a combo alias. A collapsed fallback tries a usable unmetered target before refusing. Unmarked targets retain existing behavior; metering is declared by the operator rather than detected automatically.
+
+For example, a failover chain can target Anthropic OAuth, then Cursor, then `{ "provider": "anthropic-apikey", "model": "claude-opus-5-5", "metered": true }`. Without consent, exhaustion returns the last unmetered error, with one exception: an earlier 429 or 402 quota refusal takes precedence over a later 400, 401 or 403. If the subscription target returns 429 and Cursor then refuses with 401 or 403, the caller receives the subscription's 429, because the spent subscription explains the failure and Cursor's credential refusal does not. Dashboard saves retain omitted target metering and combo consent; explicitly setting either to false clears it. These consent fields are configured through the config file or API; the combo flag is also available through the CLI, while the dashboard does not expose it.

Status preserves saved native identities, while manual/preset replacement requires explicit reset of native-inclusive order. Manual input is a full unique routed permutation with the observed featured prefix; settings/identity rereads reject observable drift without claiming CAS. `src/cli/model-picker-ordering.ts` mirrors the GUI's pure identity/sort projection without importing GUI code into the CLI. Independent ordering fixtures and test-only GUI conformance exercise the deliberate shared contract. Most-used consumes complete all/all requested-model usage, not representative resolved-model attribution. The registry declares the existing display-name PUT; its handler remains authoritative, including saved-but-failed HTTP503.

The helpers do not select endpoints, grant authority, perform writes or execute generic CRUD. Existing provider receipt semantics remain separate. Local discovery refusals raised by `runtimeBaseUrl` before any request carry a typed `RuntimeApiError.code` (`proxy_not_running`, `client_role_management_unavailable`) and render a fixed "No request was sent" message instead of uncertain-write wording; integration-route errors (normalized, unredirected path) may append a fixed recovery line keyed on the closed `reason` set; the writer's `message` prose is never echoed.

 # Config Surface
 
-Quota activation reuses the existing next-reset fields without adding a polling configuration key. See the [quota activation contract](providers/openai-tiers.md#public-provider-contract). `src/types/config.ts` defines `anthropicAccountPool.routes` as ordered model rules. `src/oauth/anthropic-model-routes.ts` validates bounded names, full case-sensitive globs and stored account IDs; `src/config/diagnostics.ts` rejects malformed candidate writes. Load retains a malformed hand edit so unrelated providers survive, while the enabled Anthropic selector refuses it locally before dispatch. Saved rules remain inert when the pool is disabled; affinity is process-local. Request logs use only the rule’s 1-based `route:#<n>` position, never its configured name. `src/cli/hub-disable.ts` removes interdependent hub/loopback/role/hostname settings through `mutatePersistedConfig` and `validateConfigCandidate` in one commit. Top-level deletion intent uses `src/config/rebase-provenance.ts` and authoritative disk provenance in `src/config/live-reconcile.ts` to preserve removed hub bindings through later live saves, `src/config/live-topology.ts` keeps an independent active-topology baseline and merges desired next-start settings into a separate persistence projection, retaining actual socket identity and live hub/client topology during guarded saves and OAuth disk adoption. Client connections and runtimeRole remain one topology unit through connect/disconnect, including fresh disk-only connections. Disk additions/value updates and deletions all survive repeated saves without changing active topology. `src/config/api-key-reconcile.ts` merges key rows by stable ID under the existing save lock; either side's revocation defeats stale edits while disjoint names and rotations merge; unchanged live key membership/order adopts persisted ordering. `tests/config/hub-disable-live-save.test.ts` exercises disable followed by live key creation, rename, rotation, unrelated settings and repeated saves. Saved API keys have no immutable enrollment marker; explicit exact-ID revocation preserves all unselected keys.
+`src/config/schema/leaf-validators.ts` accepts only boolean `apiKeys[].allowMeteredComboTargets`; malformed entries are dropped rather than promoted. `src/types/config.ts` and combo validation define optional boolean target `metered`, normalized false when omitted, and optional per-combo `allowMeteredTargets` (default false, literal boolean validation shared by config schema and management API). Explicit consent is required under the [combo runtime contract](runtime.md#request-local-target-compatibility). Quota activation reuses the existing next-reset fields without adding a polling configuration key. See the [quota activation contract](providers/openai-tiers.md#public-provider-contract). `src/types/config.ts` defines `anthropicAccountPool.routes` as ordered model rules. `src/oauth/anthropic-model-routes.ts` validates bounded names, full case-sensitive globs and stored account IDs; `src/config/diagnostics.ts` rejects malformed candidate writes. Load retains a malformed hand edit so unrelated providers survive, while the enabled Anthropic selector refuses it locally before dispatch. Saved rules remain inert when the pool is disabled; affinity is process-local. Request logs use only the rule’s 1-based `route:#<n>` position, never its configured name. `src/cli/hub-disable.ts` removes interdependent hub/loopback/role/hostname settings through `mutatePersistedConfig` and `validateConfigCandidate` in one commit. Top-level deletion intent uses `src/config/rebase-provenance.ts` and authoritative disk provenance in `src/config/live-reconcile.ts` to preserve removed hub bindings through later live saves, `src/config/live-topology.ts` keeps an independent active-topology baseline and merges desired next-start settings into a separate persistence projection, retaining actual socket identity and live hub/client topology during guarded saves and OAuth disk adoption. Client connections and runtimeRole remain one topology unit through connect/disconnect, including fresh disk-only connections. Disk additions/value updates and deletions all survive repeated saves without changing active topology. `src/config/api-key-reconcile.ts` merges key rows by stable ID under the existing save lock; either side's revocation defeats stale edits while disjoint names and rotations merge; unchanged live key membership/order adopts persisted ordering. `tests/config/hub-disable-live-save.test.ts` exercises disable followed by live key creation, rename, rotation, unrelated settings and repeated saves. Saved API keys have no immutable enrollment marker; explicit exact-ID revocation preserves all unselected keys.
 
 Native function-result injection follows [the separate opt-in control contract](transports/streaming-health.md#experimental-native-function-result-injection); this surface does not infer upstream support or alter its defaults.

-Anthropic OAuth account DTOs include `autoSwitchThresholdOverride` (integer or null),
+`src/server/management/combo-routes.ts` retains omitted `metered: true` metadata by trimmed provider/model identity during dashboard-shaped saves. Explicit false clears the flag; false defaults are omitted from persisted targets. Omitted combo `allowMeteredTargets` survives saves and renames; explicit false clears it and stays sparse. The CLI exposes `--allow-metered-targets on|off`, and receipts preserve the boolean. Key and loopback operator consent follow the [runtime contract](runtime.md#request-local-target-compatibility). Anthropic OAuth account DTOs include `autoSwitchThresholdOverride` (integer or null),
 `autoSwitchThreshold` (pool default) and `effectiveAutoSwitchThreshold`. The dedicated
 `PUT /api/oauth/accounts/auto-switch` accepts `{ provider: "anthropic", accountId, threshold }`;
 explicit null restores inheritance and missing/invalid values fail. Other providers are rejected.

+`src/server/admission-model-scope.ts` grants metered combo eligibility to a matching configured key with literal `allowMeteredComboTargets: true`, or to local/missing admission when the selected combo has literal `allowMeteredTargets: true` and the full business config satisfies `!isApiAuthRequired(config)`. Configured and environment admissions never inherit combo consent; linked keys retain their key consent requirement even on a loopback Home. The full hostname also prevents secondary loopback listeners on public proxies from granting operator consent. `src/server/responses/core-combo.ts` filters marked targets on initial, failure and recovery selection for every strategy. A route the router collapsed to one combo pick outside that loop (a subagent fallback naming a combo alias) is re-picked among usable unmetered targets in `captureInboundRoutePolicy` of `src/server/responses/request-prepare.ts` when its pick is metered without consent, or refused if none remain; the replacement retains combo metadata and passes destination policy/scope checks. Request headers never grant consent; absent/false consent denies marked targets; provider/model scopes remain independent. `src/cli/combo-input.ts` accepts and validates the optional target boolean. Unmarked targets retain existing behavior; metering is operator metadata, not automatic billing detection.

 # Responses Failover And Replay
 
- `src/server/responses/request-transport.ts` resolves the final Anthropic model ID once for each enabled-pool request and holds its model route through admission. The three account-refusal retry sites in `adapter-dispatch.ts`, `adapter-continuation.ts` and `sidecar-execution.ts` use the same route, keep the original refusal if no replacement exists inside it, and preserve existing send and output replay limits. A local cooldown returns 429 with the earliest known Retry-After among accounts the route can use when they recover, and answers a usage limit when every held account is on spent quota ([quota exhaustion answer](../providers/anthropic-account-pool.md#quota-exhaustion-answer-and-fresh-read-recovery)); explicit fallback includes usable ordinary-pool accounts even when the saved route IDs have been removed, while a strict route stays route-scoped. Selection, refusal and 429-rotation logs use the rule’s 1-based `route:#<n>` position, never its name.
+Combo `metered` eligibility follows the [runtime consent contract](../runtime.md#request-local-target-compatibility), including recovery selections. In `src/server/responses/run-turn-execution.ts`, streaming and buffered pre-output failures retain structured adapter status/type/code via `adapterFailureFromEvent`, and `formatErrorResponse`'s `classified` option keeps that verdict in the child body instead of re-deriving it from the status, wherever its type and message add nothing to what the status alone says; a verdict read from the message (quota, credentials, cyber policy, context overflow, catalog size) still outranks a generic adapter code, and spend-ledger, cyber-policy and replay-refusal overrides still win, and `consumeComboFailure` re-applies the client allowlist. Spend-ledger storage refusal remains 503. This preserves an exhausted subscription chain’s 429 response, a child's `insufficient_quota`, and the cool-free hop on `unsupported_input_modality` in `src/combos/failover.ts`. Coverage: `tests/adapters/anthropic/anthropic-subscription-chain.test.ts` and `tests/responses/responses-combo-run-turn-classified-failure.test.ts`.  `src/server/responses/request-transport.ts` resolves the final Anthropic model ID once for each enabled-pool request and holds its model route through admission. The three account-refusal retry sites in `adapter-dispatch.ts`, `adapter-continuation.ts` and `sidecar-execution.ts` use the same route, keep the original refusal if no replacement exists inside it, and preserve existing send and output replay limits.

Subject: [PATCH 19/72] feat(pricing): support per-model prompt-length
 overrides (carry #6738) (#7160)

* feat(pricing): support per-model prompt-length overrides (carry #6738)

Port f098a981d7e128da14322a3aa215408b6c9e889e onto dev 7640a942b, retaining current topology/API-key reconciliation and test inventory entries.

Co-authored-by: Valerio Coltre <2657230+colthreepv@users.noreply.github.com>

* test(gui): drop an unused import from the price-cost contract test

Co-authored-by: Valerio Coltre <2657230+colthreepv@users.noreply.github.com>

* fix(pricing): preserve legacy policies and contain modal comparisons

Reuse pure shared model-cost validators during OpenAI tier migration, preserve valid policies, and retain strict rejection of malformed rows. Keep the pricing comparison menu inside the native dialog and cover policy migration, CLI initialization, and modal selection regressions.

Co-authored-by: Valerio Coltre <2657230+colthreepv@users.noreply.github.com>

* docs(structure): keep the integration-tested merge wording

Align structure/config.md, structure/gui-and-management-api.md with the tree verified before merge.

 Les routes `anthropicAccountPool.routes` associent un modèle à des identifiants de comptes OAuth Anthropic enregistrés. La première règle correspondante (`match`, glob sensible à la casse) limite la sélection initiale et les reprises 429 lorsque le pool est activé. `fallback: true` élargit la sélection seulement si aucun compte de la règle n’est éligible.
+
+
+### `promptLengthPricing`
+
+Le champ facultatif `promptLengthPricing` complète les quatre tarifs de base. `mode: "automatic"` (ou champ absent) conserve les règles de contexte du catalogue ; `mode: "flat"` les désactive. Avec `mode: "custom"`, `thresholdTokens` est un entier positif sûr, `comparison` vaut `"gt"` (>) ou `"gte"` (≥), et `rates` contient les quatre tarifs alternatifs absolus. Le seuil compte tous les jetons du prompt, y compris les lectures et écritures du cache, sans la sortie. Les tarifs sélectionnés couvrent toute la requête, sortie comprise, et remplacent la règle de contexte du catalogue des deux côtés du seuil. Les ajustements Fast/Priority s'appliquent une seule fois après la sélection des tarifs et suivent la relation Priority publiée dans le catalogue pour ce modèle ; l'estimation n'est indiquée comme borne inférieure que lorsque le catalogue déclare la relation `lower-bound` (actuellement xAI Grok) ; un modèle sans règle de catalogue applique le multiplicateur Priority une seule fois. Configurez ces options dans **Models → Price**. **Reset to automatic** supprime tous les tarifs et la règle personnalisés. Les anciennes configurations restent compatibles ; ces paramètres concernent les estimations affichées.

+### Prompt-length pricing
+
+In **Models → Price**, keep four base rates and choose a prompt-length mode:
+
+- **Automatic** keeps the catalog context rules. It is also the behavior of existing four-rate overrides without a policy.
+- **Flat rate** uses the base rates at every prompt length, disabling catalog context adjustments.
+- **Custom threshold** selects four absolute alternative rates using `>` or `≥` and one token threshold. The custom policy replaces the catalog context rule on both sides of the threshold.
+
+All prompt tokens count, including cache reads and writes, before billable-input subtraction.
+Output does not count toward the threshold. Once crossed, the alternative rates apply to the
+entire request, including output, not only the excess tokens. Custom rates are standard-speed
+rates: an applicable Fast/Priority premium applies once after the rates are selected and follows
+the catalog's relation between Priority and long-context pricing for that model. A confirmed
+Priority request shows the custom estimate as a lower bound only when the catalog declares that
+relation as `lower-bound`, as for xAI Grok, which publishes no combined rate. A model with no
+catalog context rule applies any Priority multiplier once. These settings control estimates; they
+do not change provider billing.
+**Reset to automatic** deletes the entire override and restores catalog prices and rules. Saving or
+editing the config updates live estimates and historical totals.
+
+For example, a Haiku 5.5 override with alternative rates strictly above 100,000 prompt tokens:
+
+```json
+{
+  "modelCosts": {
+    "claude-haiku-5-5": {
+      "input": 0.10,
+      "output": 0.50,
+      "cacheRead": 0.01,
+      "cacheWrite": 0.125,
+      "promptLengthPricing": {
+        "mode": "custom",
+        "thresholdTokens": 100000,
+        "comparison": "gt",
+        "rates": { "input": 0.50, "output": 2.50, "cacheRead": 0.05, "cacheWrite": 0.625 }
+      }
+    }
+  }
+}
+```
+
+This is an example of user-defined prices, not an official Haiku price list.
+Any positive safe-integer threshold, including `272000`, is supported; use `"gte"` for inclusive
+comparison. All four alternative rates are required and follow the base-rate limits, including zero.
+The other policy is `{ "mode": "flat" }`. Omit `promptLengthPricing` to retain automatic context
+rules with your base prices; an explicit `{ "mode": "automatic" }` is accepted and means the same,
+and saves from the dashboard or API store it as an absent field.
+
+Legacy `openai-multi` model price overrides retain valid prompt-length policies when startup
+migrates them to `openai`, including overrides keyed by `openai-multi/<model>`.
+
 ### Renamed API-key presets
 
 A provider saved under another name, such as `CommandCode`, inherits missing reasoning-effort metadata when its adapter and fixed API-key endpoint match a registry preset. Your explicit per-model lists, including `[]`, remain authoritative. An omitted provider-wide list inherits the preset default; an explicit list remains unchanged. This does not match OAuth, unrelated endpoints, or templated/custom endpoint presets.

+`PUT` on the same route accepts `{ modelId, cost }`, where `cost` contains
+`{ input, output, cacheRead, cacheWrite }` and optionally `promptLengthPricing`, or is `null` to reset.
 All four rates must be finite numbers from 0 through 1,000,000, in USD per 1M tokens.
 Unknown fields and malformed rates are rejected. A write preserves other models' overrides
 and returns `{ ok: true, provider, modelId, cost }`; reset returns `cost: null`.
 
+The **Model price** dialog offers **Automatic**, **Flat rate**, and **Custom threshold**
+prompt-length pricing. Automatic (also the default when the policy is absent) retains catalog
+context rules with the saved base rates. Flat disables context adjustments. Custom selects four
+absolute alternative rates using one positive safe-integer `thresholdTokens` and `comparison`
+(`"gt"` for `>`, `"gte"` for `≥`). All prompt tokens count, including cache reads and writes;
+output does not. The selected rates apply to the whole request, including output, not just the
+excess tokens. Custom replaces the catalog context rule both below and above its threshold.
+Custom rates are standard-speed rates: an applicable Fast/Priority adjustment applies once after
+rate selection and follows the catalog's Priority relation for that model. Only a model whose
+catalog relation is `lower-bound` reports `priorityLowerBound: true`; a model with no catalog rule
+applies any Priority multiplier once.
+`{ "mode": "automatic" }` is accepted on write and stored as an absent policy, so GET and PUT
+receipts never contain it.
+**Reset to automatic** removes the entire override, including base rates and the policy.
+See the [configuration example](../configuration/providers/#prompt-length-pricing).

Для `mode: "custom"` задайте положительное безопасное целое `thresholdTokens`, `comparison`: `"gt"` (>) или `"gte"` (≥), и четыре абсолютных альтернативных тарифа в `rates`. Порог учитывает все токены промпта, включая чтение и запись кэша, но исключает вывод. Выбранные тарифы применяются ко всему запросу, включая вывод, и заменяют правило каталога по обе стороны порога. Корректировки Fast/Priority применяются один раз после выбора тарифов и следуют опубликованному в каталоге соотношению Priority для этой модели; оценка помечается как нижняя граница, только если каталог объявляет соотношение `lower-bound` (сейчас это xAI Grok); для модели без правила в каталоге множитель Priority применяется один раз. Настройка доступна в **Models → Price**. **Reset to automatic** удаляет всё переопределение, включая базовые тарифы и правило. Старые конфигурации совместимы; настройки относятся к отображаемым оценкам.

 # Config Surface
 
-`src/config/schema/leaf-validators.ts` accepts only boolean `apiKeys[].allowMeteredComboTargets`; malformed entries are dropped rather than promoted. `src/types/config.ts` and combo validation define optional boolean target `metered`, normalized false when omitted, and optional per-combo `allowMeteredTargets` (default false, literal boolean validation shared by config schema and management API). Explicit consent is required under the [combo runtime contract](runtime.md#request-local-target-compatibility). Quota activation reuses the existing next-reset fields without adding a polling configuration key. See the [quota activation contract](providers/openai-tiers.md#public-provider-contract). `src/types/config.ts` defines `anthropicAccountPool.routes` as ordered model rules. `src/oauth/anthropic-model-routes.ts` validates bounded names, full case-sensitive globs and stored account IDs; `src/config/diagnostics.ts` rejects malformed candidate writes. Load retains a malformed hand edit so unrelated providers survive, while the enabled Anthropic selector refuses it locally before dispatch. Saved rules remain inert when the pool is disabled; affinity is process-local. Request logs use only the rule’s 1-based `route:#<n>` position, never its configured name. `src/cli/hub-disable.ts` removes interdependent hub/loopback/role/hostname settings through `mutatePersistedConfig` and `validateConfigCandidate` in one commit. Top-level deletion intent uses `src/config/rebase-provenance.ts` and authoritative disk provenance in `src/config/live-reconcile.ts` to preserve removed hub bindings through later live saves, `src/config/live-topology.ts` keeps an independent active-topology baseline and merges desired next-start settings into a separate persistence projection, retaining actual socket identity and live hub/client topology during guarded saves and OAuth disk adoption. Client connections and runtimeRole remain one topology unit through connect/disconnect, including fresh disk-only connections. Disk additions/value updates and deletions all survive repeated saves without changing active topology. `src/config/api-key-reconcile.ts` merges key rows by stable ID under the existing save lock; either side's revocation defeats stale edits while disjoint names and rotations merge; unchanged live key membership/order adopts persisted ordering. `tests/config/hub-disable-live-save.test.ts` exercises disable followed by live key creation, rename, rotation, unrelated settings and repeated saves. Saved API keys have no immutable enrollment marker; explicit exact-ID revocation preserves all unselected keys.

Explicit consent is required under the [combo runtime contract](runtime.md#request-local-target-compatibility). Model-price overrides follow the [pricing contract](pricing.md). Quota activation reuses the existing next-reset fields without adding a polling configuration key. See the [quota activation contract](providers/openai-tiers.md#public-provider-contract). `src/types/config.ts` defines `anthropicAccountPool.routes` as ordered model rules. `src/oauth/anthropic-model-routes.ts` validates bounded names, full case-sensitive globs and stored account IDs; `src/config/diagnostics.ts` rejects malformed candidate writes. Load retains a malformed hand edit so unrelated providers survive, while the enabled Anthropic selector refuses it locally before dispatch. Saved rules remain inert when the pool is disabled; affinity is process-local. Request logs use only the rule’s 1-based `route:#<n>` position, never its configured name. `src/cli/hub-disable.ts` removes interdependent hub/loopback/role/hostname settings through `mutatePersistedConfig` and `validateConfigCandidate` in one commit. Top-level deletion intent uses `src/config/rebase-provenance.ts` and authoritative disk provenance in `src/config/live-reconcile.ts` to preserve removed hub bindings through later live saves, `src/config/live-topology.ts` keeps an independent active-topology baseline and merges desired next-start settings into a separate persistence projection, retaining actual socket identity and live hub/client topology during guarded saves and OAuth disk adoption. Client connections and runtimeRole remain one topology unit through connect/disconnect, including fresh disk-only connections. Disk additions/value updates and deletions all survive repeated saves without changing active topology. `src/config/api-key-reconcile.ts` merges key rows by stable ID under the existing save lock; either side's revocation defeats stale edits while disjoint names and rotations merge; unchanged live key membership/order adopts persisted ordering. `tests/config/hub-disable-live-save.test.ts` exercises disable followed by live key creation, rename, rotation, unrelated settings and repeated saves. Saved API keys have no immutable enrollment marker; explicit exact-ID revocation preserves all unselected keys.
 
 Native function-result injection follows [the separate opt-in control contract](transports/streaming-health.md#experimental-native-function-result-injection); this surface does not infer upstream support or alter its defaults.

+# Model Price Overrides
+
+## Configuration and API
+
+`ProviderCostOverlay` in `src/types/provider.ts` keeps four required base rates and an optional
+`promptLengthPricing` discriminated policy: `automatic`, `flat`, or `custom` with a positive
+safe-integer `thresholdTokens`, `gt`/`gte` comparison and four absolute alternative `rates`.
+Absent policy retains legacy automatic context behavior. `src/config/schema/leaf-validators.ts`
+rejects malformed/unknown nested fields on writes and copies only validated policy fields for
+display, dropping an explicit `automatic` policy so absence is the single stored form of
+Automatic; load degradation drops an invalid model row without losing the provider.
+
+`src/providers/openai-tiers.ts` accepts these same rate and policy shapes through the shared
+`validCost4` predicate in the pure `src/usage/user-cost-validation.ts` module when migrating
+legacy `openai-multi` overlays. It rejects unknown row
+fields and malformed policies, and preserves valid policies while rewriting model keys to `openai`.
+`tests/adapters/openai/openai-provider-option-migration.test.ts` covers preservation and rejection.
+
+`src/server/management/model-routes.ts` serves `GET/PUT /api/providers/{provider}/model-costs`.
+GET and successful PUT receipts retain all four rates and the optional validated policy.
+A `cost: null` write removes the entire model override. Writes retain atomic persistence,
+rollback and sibling-model preservation. `tests/server/model-costs-prompt-length-pricing.test.ts`
+covers persistence, receipts, reset, rollback and external edits.
+
+`src/config/live-reconcile.ts` scopes explicit pricing PUT intent to one complete model row.
+After recursive reconciliation under the config mutation lock, it reapplies that row (or its
+deletion) and validates the final candidate before publication. This prevents concurrent mode
+changes from mixing Custom fields into Flat/Automatic policies, and honors replacement even
+when the submitted base rates equal the old baseline. Unrelated saves still adopt disk edits.
+`src/cli/models-runtime.ts` reads the complete policy in `cost` and projects only base rates in
+`effectiveCost`. `set-price` reads the current row first and carries that model's policy into
+the replacement row, so a base-rate edit never silently drops a Flat or Custom policy; its receipt
+must echo the same policy, with absent and `automatic` treated as equal.
+
+## Dialog and estimates
+
+`gui/src/components/ModelPriceDialog.tsx` edits base rates plus Automatic, Flat rate or Custom
+threshold pricing. Automatic retains catalog context rules with the saved base tuple. Flat skips
+context adjustments; Custom replaces the catalog rule on both sides of its single threshold.
+Parsing, draft building, per-field validation and receipt comparison live in the pure
+`gui/src/components/model-price-cost.ts`; the dialog sends no policy for Automatic, validates
+complete policy receipts before refreshing the model list and retains its uncertain-outcome/reload
+flow. `gui/tests/models-price-editor.test.tsx` covers this behavior.
+The comparison Select renders its menu inside the modal dialog so native modal inertness does
+not block pointer or keyboard interaction with its options.
+
+`src/usage/cost.ts` selects rates against inclusive `usage.inputTokens`, before subtracting cache
+reads/writes for cost estimates; output is excluded from threshold selection. Alternative rates
+apply to every token bucket of the request. Custom rates are standard-speed rates that stand in
+for the catalog long-context rate, so a crossed threshold follows the catalog's
+`confirmedPriorityRelation` for that model: `stack` (or no catalog rule) applies the Priority
+multiplier once, `lower-bound` keeps the custom rates and sets `priorityLowerBound`, and
+`exclusive` prices a confirmed Priority request from the base rates. Confirmation requirements are
+unchanged. `customThresholdApplied` stays separate from the catalog `contextTier` marker and is
+set only when the custom rates priced the request. Each Combo attempt selects its own tuple.
+`tests/usage/usage-prompt-length-pricing.test.ts` pins boundaries, cached prompts, whole-request
+rates, compatibility, Combo and Fast/Priority behavior.
+It also verifies Automatic Haiku overrides at 99,999/100,000/100,001 inclusive prompt tokens,
+including cache reads/writes and the inherited catalog band for both Anthropic OAuth pools.
+
+`src/usage/user-cost-overlays.ts` copies the complete policy into its versioned registry:
+policy-only edits invalidate price memoization and usage caches; identical reloads remain stable.
+`tests/server/model-costs-pricing-cache.test.ts` exercises warmed cache invalidation and reset.
+These settings affect estimates, not upstream billing or official catalog price lists.

Subject: [PATCH 20/72] feat(combos): enroll text-only members in vision
 sidecar (carry #4932) (#7162)

* feat(combos): enroll text-only members in vision sidecar (carry #4932)

Port c9cda1b5a95292bc280ce1ec7dd942820c08cba1 onto current dev, preserving atomic enrollment, runtime consumer classification and rename rollback. Keep new regressions in a registered sibling file.

* fix(combos): close enrollment gaps found in review (carry #4932)

- Send no visionSidecarTargets while a blocked member forces the image
  switch off, so a save never declares the remaining members text-only.
- Reject enrollment of a model whose provider modelInputModalities hint
  lacks text instead of overriding it with a text-only declaration.
- Update the MiniMax combo picker test to the sidecar-coverage contract.
- Align pt/vi unavailable hints with English, revert an unrelated fr
  apostrophe change, and style the disabled-sidecar warning with the
  amber warning token.

* perf(models): share registry enrichment across sidecar-consumer rows

GET /api/models classified every row with isVisionSidecarConsumer, which
rebuilds the registry-enriched provider per call (~0.1 ms/row, ~170 ms for
a 2000-row listing). A per-listing classifier reuses the eligibility
module's existing enrichment cache, so verdicts are unchanged.

* fix(gui): use hash navigation for the sidecar dashboard link and a single modality pass

Co-authored-by: x3M3x <x3M3x@users.noreply.github.com>

* test(gui): pin sidecar-eligible members keeping the combo Image switch on

Text-only and mixed image/text members are covered by the Vision Sidecar, so the switch stays enabled; unknown and audio-only members still force it off. The cached capability rows now carry visionSidecarConsumer.

* fix(combos): validate the merged modelCapabilities map before enrolling sidecar members

A provider already at the modelCapabilities cap accepted a valid one-entry patch and persisted an oversized map that load-time sanitization then truncated, dropping the new text-only declaration. The route now validates the merged map (400, nothing written) and re-checks it under the config lock.

 omitting the field) keeps the automatic intersection.
 
+In the dashboard, the **Image / multimodal** switch can be enabled whenever every target has
+known image or text input capabilities. Native image members stay unchanged; text-only members are
+automatically declared text-only on save (`modelCapabilities[model].inputModalities = ["text"]`)
+so the [Vision Sidecar](/guides/sidecars/) describes their images. The switch's hint names the
+members that will be enrolled. A member whose modalities are unknown or have no text input (for
+example an audio-only model) cannot be covered by the sidecar; it keeps the switch unavailable and
+is named in the hint. If the [Vision Sidecar](/guides/sidecars/) is disabled globally, enabling the
+switch shows a warning linking to the dashboard: enrollment still saves, but images are replaced
+with an omission note and requests continue without image descriptions until the sidecar is
+re-enabled. Turning the switch off disables image input for the combo
+but keeps those provider declarations, and `PUT /api/combos` accepts the same enrollment as an
+optional top-level `visionSidecarTargets` array of exact `{ provider, model }` targets
+(request-only; it is never stored on the combo and is rejected while `imageInput` is
+`"disabled"` when the enrollment list is non-empty). Entries that already accept image input or
+are declared without text are rejected with HTTP 400 rather than overwritten, entries the sidecar
+already covers are skipped, and a save refused before publication restores the combo and every declaration together.
+Removing a member from the combo does not remove its text-only declaration; clear it in the
+provider editor if you no longer want it.

Complete POST/PUT replacements reject tombstones. File reads retain valid axes; malformed explicit modalities restrict to text with a diagnostic. The two catalog writers receive explicit config and gather fingerprints include the map. This storage contract alone does not activate a context tier, advertise a larger window or enable video processing. Separately, `modelContextTiers` actively selects `default` or `long_context` for GitHub Copilot models: config and management writes validate exact IDs, PATCH merges entries and null clears the map, CLI edit writes the map, and OAuth login preserves it.
 
-The text-only consumer reads exact inputModalities declarations before legacy hints. CLI add/edit `--text-only` targets one model and preserves sibling declarations; `src/vision/eligibility.ts` routes declared text-only models into existing image-description or explicit-omission handling. Positive routed image declarations override stale candidate metadata, while native catalog authority retains its existing legacy policy.
+The text-only consumer reads exact inputModalities declarations before legacy hints. CLI add/edit `--text-only` targets one model and preserves sibling declarations; `src/vision/eligibility.ts` routes declared text-only models into existing image-description or explicit-omission handling. Positive routed image declarations override stale candidate metadata, while native catalog authority retains its existing legacy policy. `PUT /api/combos` accepts a request-only `visionSidecarTargets` array of exact combo-member `{ provider, model }` pairs (validated against the submitted combo's normalized targets, deduplicated, rejected while `imageInput` is `"disabled"`). An entry whose provider is unconfigured, whose model already accepts image input through any source, or whose exact declaration, custom row, or provider `modelInputModalities` hint lacks `text` is rejected with 400 instead of being overwritten; an entry the sidecar already covers through any runtime source (exact declaration, custom row, `noVisionModels`, legacy record, registry enrichment) is skipped as a no-op. Accepted entries merge `inputModalities: ["text"]` through the same validation/merge helpers, and the combo write, reference migrations, disabled-selector rewrite and capability patches commit in one provider-patch transaction — a failed save restores all of them. The field never persists under `config.combos`, and removing a member from the combo leaves its provider declaration in place until cleared explicitly.

 The [explicit model-capability contract](config.md#explicit-per-model-capability-declarations) preserves operator declarations through provider storage and catalog capture; it does not infer upstream capability or change this surface's routing behavior.
 
-Exact [model input declarations](config.md#explicit-per-model-capability-declarations) now feed text-only eligibility and catalog hints; existing image-description/omission handling consumes them before the main upstream send.
+Exact [model input declarations](config.md#explicit-per-model-capability-declarations) now feed text-only eligibility and catalog hints; existing image-description/omission handling consumes them before the main upstream send. The Combos page sends non-image members as the request-only `visionSidecarTargets` field on `PUT /api/combos` whenever the Image switch is enabled, so text-only enrollment needs no manual provider edit. The GUI classifies members from the authoritative `visionSidecarConsumer` flag served on `/api/models` rows, so a member covered only by legacy `noVisionModels` keeps its sidecar classification after reload. Members whose modalities are unknown or have no text input keep the switch unavailable and are named in the hint; a member later removed from the combo keeps its provider declaration until cleared in the provider editor.
 
 The raw provider editor round-trips `autoReviewModel` and `autoReviewModelOverrides` through editor-owned DTO fields. POST/PATCH/PUT share validation; PUT copies schema-normalized values into the persisted and live candidate before adoption. Canonical `openai` rejects these fields, including clear forms. Field-masked writes (PATCH, editor PUT, reload) pin every registry-seed key and ignore operator overlays the seed never defines, most commonly `selectedModels`; POST keeps the exact-key comparison. Canonical `openai` still rejects `allowPrivateNetwork`, which must not short-circuit destination DNS checks on the ChatGPT forward row. Existing authentication, origin checks and stale-baseline protection still govern the writes. See [reviewer projection](catalog.md#provider-scoped-approval-reviewer). Stored Direct substitution follows the [credential identity contract](providers/openai-accounts.md#sidecars-management-and-ui): both synchronous and asynchronous materializers discard the caller account header before applying the stored credential; ordinary native Direct passthrough is unchanged.

 Automatic account exhaustion and recovery use the [spendable Codex credit evidence contract](providers/openai-tiers.md#spendable-codex-credits), including independent freshness, upstream refusal, and reset-ticket separation. The PINNED badge confirms before sending a null selection, which clears the pin and returns routing to automatic while bound threads keep their captured account. The dashboard also sends `expectedPinnedAccountId`; the persisted mutation rejects a changed pin with `account_pin_changed` before writing. Refused or uncertain releases reload `/active` and close the old confirmation without claiming that the prior selection survived.

Subject: [PATCH 21/72] feat(oauth): reset-first strategy for generic OAuth
 pools (carry #5408) (#7167)

* feat(oauth): reset-first strategy for generic OAuth pools (carry #5408)

Generic OAuth pools (Antigravity, xAI, Cursor, Kiro and the rest) can store
and run reset-first under pool.kernel: the first attempt and a 429 rotation
prefer the non-exhausted account whose weekly (else 5-hour) quota resets
soonest, with headroom breaking ties. A passive provider with partial
evidence keeps headroom order. The Anthropic kind still refuses it.

The first-attempt pick uses the same eligible set as round-robin, so an
Antigravity account whose model roster omits the requested model is not
chosen. ocx account pool --strategy now accepts reset-first for generic
pools as the server already does for ocx account strategy.

Carried from #5408 (source head 2db983800a02785250cc3ebed86f399bc772303e).

Subject: [PATCH 22/72] fix(oauth): print fixed CLI login errors instead of
 provider bodies (#7171)

* fix(oauth): print fixed CLI login errors instead of provider bodies

* fix(oauth): keep standard error codes and namespace errors in CLI login failures

Print an allowlisted RFC 6749/8628 error code next to the HTTP status,
label unreachable or timed-out token endpoints, and report a Codex
account namespace collision before the login starts instead of as a
generic authentication failure.

* fix(oauth): report namespace collisions as configuration errors in login

The default ocx login path now prints only the public OAuth vocabulary,
so the plain Error thrown for a provider name that collides with a Codex
account namespace read as a generic authentication failure and broke
cli-provider's login collision test. Throw a typed fixed-text error that
the public message allowlist admits and label it configuration_error.

* fix(oauth): classify wrapped xAI connection failures as network errors

* fix(oauth): report Pool 2 preflight configuration failures safely

* fix(oauth): guard Pool 2 at the shared CLI entry point

+The [CLI management contract](cli-management.md#cli-readiness-diagnostics) owns terminal-safe human diagnostics, structured-output fidelity and capability argument failures. Its [data-key and observation contract](cli-management.md#data-key-probes-and-observation-streams) also owns explicit stdin cancellation, credential separation and bounded follow lifetimes. `src/oauth/login-cli.ts` delegates failed provider logins to `src/oauth/login-cli-errors.ts`: the terminal prints the public OAuth message with a fixed reason (a validated HTTP status plus an allowlisted RFC 6749/8628 error code, `network_error`, `timeout`, `configuration_error`, or `oauth_authentication_failed`) and exits 1, so provider response text never reaches the terminal (`tests/oauth/oauth-login-cli-errors.test.ts`). A status-less `XaiTokenRequestError` represents a connection failure after retries and reports `network_error` without exposing its cause. Pool 2 checks raw config ownership before tolerant config loading or prompting; custom-row collisions and unreadable or malformed config are fixed `configuration_error` diagnostics.

Subject: [PATCH 23/72] test(claude): end the linger upload pump when the
 socket closes (#7180)

Bun drops a TLS write callback still pending when the peer resets the socket.
The armed drop resets the uploading client, so a chunk in flight at that
moment left the pump unsettled and stop() hung until the 60s test timeout
(macos 1/3, run 38699018462). Settle the pump on close as well.

Subject: [PATCH 24/72] fix(codex): protect the desktop authority key
 in-process on Windows x64 (#7181)

* fix(codex): protect the desktop authority key in-process on Windows x64

Every protect/unprotect spawned Windows PowerShell and loaded System.Security,
which cost seconds of cold start and exceeded the 20s bound on a loaded Windows
runner. Call CryptProtectData/CryptUnprotectData through bun:ffi instead, with
crypt32 loaded from the GetSystemDirectoryW path. Windows ARM64 keeps the
PowerShell helper. Blobs stay compatible in both directions.

* fix(codex): zero every unprotected DPAPI buffer and load kernel32 from System32

* fix(codex): free the DPAPI output buffer on every path after a successful call

* fix(codex): wipe unprotected DPAPI output natively before freeing it

+# Gemini Argon output separation
+
+A report of reasoning-looking assistant output prompted comparison of the Google response
+classifier with CLIProxyAPI and cc-switch. The inspected classifier already separates marked
+thoughts. This unit verifies that separation through every client protocol using synthetic
+markers, and documents the boundary without claiming the original observation is reproduced.
+
+## Loop specification
+
+- Archetype: satisfy-spec; one C3 verification/documentation work phase.
+- Trigger/goal: investigate Argon output separation and deliver an evidence-backed PR to dev.
+- In scope: synthetic Argon integration tests, their layout registration, and current Google docs.
+- Non-goals: heuristic text censorship, runtime changes without a demonstrated defect, private
+  session transcripts, user configuration changes, deployment, other worktrees, native PR stacks.
+- Verifier: new protocol test plus adjacent Google/direct-encoder tests; typecheck, test layout,
+  file-size, privacy and structure gates; docs build; required CI at the PR head.
+- Stop: coverage/docs merged with passing relevant checks, or a concrete blocker recorded.
+- Memory artifact: this unit and local `.tmp/argon-protocol/` evidence; no memory-store writes.
+- Outcomes: DONE for the verification PR; runtime NOOP if marked thoughts remain separated.
+  Do not claim the reported live symptom fixed merely because synthetic tests pass.
+- Escalation: a demonstrated defect changes the plan before patching; unavailable live evidence
+  remains an explicit limitation. Existing user authority includes push/PR/merge, no release.
+- Bounds: none stated; host limits apply. Tools: local Bun, read-only public Aside/GitHub research,
+  repository-scoped GitHub publication. No production credentials are needed for tests.
+
+## Evidence and hypotheses

+- H1: the adapter converts marked thoughts to answer text. Falsifier: mixed marked/unmarked
+  synthetic parts preserve separate channels in streaming and buffered responses.
+- H2: a client converter collapses channels. Falsifier: actual Responses, Chat and Messages
+  handlers keep thought markers out of ordinary answer fields with direct routing on and off.
+- H3: upstream ordinary text or client rendering explains the observation. Static tests cannot
+  establish this; never reclassify prose by its wording or infer a root cause from test success.
+
+Source anchors: `src/adapters/google.ts:716`, `:989`, `:1378`, `:1654`;
+`src/protocols/encoders/chat.ts:133`; `src/protocols/encoders/messages.ts:135`.
+CLIProxyAPI `5fc580b1d72d87a7bcfe5cfb6f479c1aea5625b3` maps `thought` to
+`reasoning_content`; cc-switch `76f99d41a66e24a5ed2e8982bc494399f306bfe6` filters
+marked thoughts from visible text. Public Aside reads succeeded with complete=true,
+truncated=false, contentVerified=true for Google thinking docs and CLIProxyAPI #6607.
+Those docs distinguish thought signatures from ordinary text visibility; #6607 is a buffering
+decision, not evidence of text leakage. Argon upstream behavior is not independently certified.
+
+Baseline: `bun test tests/adapters/google/google-hardening.test.ts
+tests/adapters/google/google-adapter.test.ts tests/adapters/google/gemini-4-argon-antigravity.test.ts
+tests/responses/responses-show-thinking-summary.test.ts`: exit 0, 158 pass at 7640a942b3.
+Work then refreshed to dev 0b13396af4; adjacent checks will run on the final patch.
+Typecheck's `include: ["src"]` does not validate new tests; Bun execution does.
+
+## Consultation
+
+Architect proposal and reflection are retained in the local coordinator evidence.
+- ARGON-SEP-01/02 accepted: keep one classifier and existing output channels.
+- ARGON-SEP-03 accepted: provenance is not proof of observed upstream behavior.
+- ARGON-SEP-04 amended: add handler-level coverage and current contract clarification.
+  Preserve historical ADR-0055 per `structure/AGENTS.md`; do not rewrite the old decision.
+- Same-architect reflection: ALIGNED against `010_verification.md`; require assertions on both
+  deltas and final accumulated payloads, and correct tool signature attachment where exposed.
+  Independent plan audit: PASS. Refreshed-base adjacent direct/encoder baseline: 131 pass, 0 fail.
+
+No new runtime fields or enums. No new runtime enforcement: tests are regression checks only;
+they can be bypassed by skipping tests, and cannot certify external client rendering.
+
+## Verification result
+
+The investigation's runtime outcome is NOOP: the tested marked thoughts stay out of ordinary
+answer fields. New coverage adds 75 cases. Deliberately changing the classifier to emit marked
+thoughts as text fails all 75; byte-for-byte restoration returns all 75 to green. No classifier
+mutation is part of the patch. The live observation's cause remains unresolved.
+
+Final focused validation on the repository-pinned Bun 1.4.3: 364 pass / 0 fail across the new
+matrix and eight adjacent Google/direct-protocol files; layout/tooling/size: 36 pass / 0 fail.
+`bun run test:changed` selects the new file only and passes all 75 cases. `bun run typecheck`,
+`bun run structure:check`, and `bun run privacy:scan` pass. `cd docs-site && bun run build`
+builds 577 pages and checks 81,202 links. Raw logs stay in local `.tmp/argon-protocol/`.
+An initial layout run under the shell's Bun 1.4.0 failed the pinned-runner check; using the
+already-installed Bun 1.4.3 resolved it without source changes.
+
+Initial fixture expectations incorrectly treated a disabled provider display default as a
+client opt-out and omitted the Messages thinking opt-in. The current tests explicitly request
+the protocol's display state, matching `core-normalize.ts` and `claude/inbound.ts`; they still
+force upstream marked thoughts when hidden to test output suppression, not just request flags.
+
+The full 2,330-file suite is not run locally: this tests/docs-only change has bounded integration
+coverage and shares the host with concurrent coding workloads. Broader coverage remains with
+the PR's required CI. Neither this exception nor synthetic tests certify external harness UI.
+
+Fresh independent final review: PASS, no actionable defects. The fresh reader identified the
+result as synthetic regression coverage, with the live symptom explicitly unverified. No prose
+change was requested. The investigation is closed with that limitation; PR integration is
+tracked by the coordinator. Runtime source is unchanged.
+
+Hosted review follow-up: restore all fixture globals in finally if spend-lease release throws;
+add independent client-only opt-outs with provider opt-in still true for all three protocols.
+A Chat opt-out mutation fails 18 cases; a Messages display-omitted mutation fails 6. All
+production files were restored byte-for-byte. These probes confirm the added cases detect
+the independent client preference, rather than passing only because the provider default is off.

+# One phase: verify the Argon output boundary
+
+Depends on current Google adapter and existing client handlers; no runtime design changes.
+
+1. NEW `tests/responses/protocol-argon-thought-boundary.test.ts`: isolated homes and synthetic
+   credentials, mock Google transport only, invoke real Responses/Chat/Messages handlers.
+   Generate `thought: true` marker parts, ordinary text (absent and false markers), signature-only
+   parts, an unmarked signed text part, and an optional tool call with synthetic signature.
+   Exercise buffered and SSE, coalesced and split SSE frames, and direct/bridge Chat/Messages.
+   Assert exact ordinary answer text in both deltas and accumulated final payloads,
+   thought marker only in reasoning/thinking fields, no
+   signature-only text, preserved tool name/args and call-bound signature where the client wire
+   exposes it, successful terminal. For independent client-only opt-outs (Responses/Chat summary none and Messages display omitted),
+   force upstream thought parts anyway and require suppression while answer and tool survive.
+   Inspect protocol trace so the direct/bridge cases prove the intended lane executed.
+2. MODIFY `scripts/test-layout/layout.json` and `tests/fixtures/test-layout-expected.json`:
+   register the new test in responses, using existing shard conventions.
+3. MODIFY `structure/providers/google.md`: describe signature-independent text classification
+   and reference the new test; preserve the historical decision record.
+4. MODIFY `docs-site/src/content/docs/guides/providers.md`: clarify Gemini thought summaries,
+   client field separation, and that unmarked ordinary text is not censored by wording.
+5. Run new tests and adjacent Google/direct-lane/encoder tests. Validate the new oracle by a
+   temporary local classifier mutation (marked thoughts become text), require failure, restore
+   bytes, then require green. No mutation may be committed.
+6. Run typecheck, test-layout/tooling, file-size, privacy, structure and docs build. Full suite
+   default applies; if concurrent workload makes it disproportionate for tests/docs only, record
+   exact focused scope and leave remaining platform/integration coverage to required CI.
+7. Fresh independent review, fix valid findings, create ordinary PR to dev using template.
+   Inspect exact-head required CI and maintainer-integration policy before the authorized merge.
+
+Acceptance is protocol correctness for the synthetic fixtures and prevention of regression.
+The original live symptom and other harnesses' rendering remain unverified; the PR and final
+report must say so. A newly demonstrated runtime defect requires a plan amendment and audit.

 modes (#7125) (#7128)

* fix(codex): honor canonical subagent limits across modes

Read and write the canonical Codex thread limit consistently with supported aliases. Keep the subagent selector available across modes, normalize child-count units, and reject stale settings responses. Cover canonical settings, mode behavior, and response ordering with focused regressions and update the capacity documentation.

* test(codex): require canonical limit after atomic feature toggle

Carry #7125 from 4bc46305ec63ed62b4f8db22b8f74a0b9460f612. The write-lock regression must assert the canonical agents table after V2-to-V1 conversion, including absence of a legacy alias. Correct the API field name in the capacity contract.

Co-authored-by: Epinephrine <27862058+luvs01@users.noreply.github.com>

* docs(codex): name the thread-limit API field consistently

* fix(codex): identify both agents limit keys in conflict warnings

+## Concurrent child limit
+
+In **Models → Model settings**, the subagent limit control sets the maximum number of concurrent
+child agents, excluding the primary agent. It remains available in v1, base and v2, including
+hybrid mode with the global v2 flag disabled. Choose the surface mode separately from this limit.
+
+Raising the cap permits more children; it does not create them automatically or guarantee faster
+execution. Start a new Codex session after changing the limit. If a long-running App host still
+uses the previous limit, restart that host.

 | Key providers | `GET /api/key-providers` exposes API-key provider presets for setup and dashboard flows, and `GET/POST/DELETE /api/keys` owns the proxy's own admission keys. Machine links live in `src/server/management/link-routes.ts`: dashboard sessions reach `GET /api/link/candidates`, `POST /api/link/probe`, `POST /api/link/confirm-host` and `POST /api/link/apply`, meaning a paired session or, on a standalone runtime, the current loopback-issued session on trusted loopback ingress; `POST /api/link/join` instead requires an operator-paired session because it durably redirects local client traffic, and also refuses a runtime that is not standalone (`409 standalone_required`) or not listening on its configured port (`409 join_port_mismatch`) before any SSH, then restarts this runtime as a client; `GET /api/link/status` reports `joinAvailable` and typed `joinDenied` causes only to GUI-session callers, distinguishing pairing, runtime-role and port refusals without changing the admin/CLI DTO, so the dashboard enables the Child role only when the join gates pass; `GET /api/link/status`, `POST /api/link/{id}/reconnect` and `DELETE /api/link/{id}` also accept the admin token on a trusted loopback ingress, and reconnect restarts a Home-initiated link's tunnel now; `POST /api/link/issue` accepts only that admin token. Tailscale-identity sessions are refused on every link route. See [Remote Link](remote-link.md). Multi-key pool per key-auth provider: `GET /api/providers/keys`, `POST /api/providers/keys`, `PUT /api/providers/keys/active`, `PUT /api/providers/keys/alias`, `DELETE /api/providers/keys` masked list, add (upsert + activate), switch, rename, and remove keys. `provider.apiKey` always mirrors the active pool entry so routing stays single-key. |
 | OpenAI account mode | Report one OpenAI Codex card with Pool/Direct controls and one API-key card. Mode PATCH persists live without restart or catalog identity changes; Pool owns account/quota controls and Direct uses caller/main login only. Main-account DTOs report real credential presence and terminal `needsReauth` state instead of treating missing/invalid native auth as an unknown quota. Selection order has its own route: `PUT /api/codex-auth/accounts/priority` takes `{ id, priority }`, where `priority` is an integer -100..100 or `null` to restore the default, accepts `__main__`, 404s an unknown id, and echoes the stored value. Re-ordering never clears thread affinity, so the response carries no `appliesImmediately`, but it does release any pin — see [`openai-tiers.md`](providers/openai-tiers.md) for why. `PUT /api/codex-auth/active` with a null id releases one too, but that drops the operator's account selection along with it, so this route is the only operator-facing way to clear a pin while leaving the selected account in place. `GET /api/codex-auth/active` reports `pinned`, true only while the manually selected account is still the effective active one, plus `pinnedAccountId`, which names the pinned account whether or not it is the active one. Surfaces should render `pinnedAccountId`: under round-robin and fill-first the pin caps the tier ceiling at its own tier while the strategy cursor moves freely inside that tier, so `pinned` goes false on a sibling's turn even though the pin is still suppressing every higher tier — which is why the dashboard badges `pinnedAccountId` and the GUI controller tracks only the id. `pinned` answers the narrower question of whether routing is *currently* on the operator's choice; no surface in this repo asks it, and a new one almost certainly wants the id instead. |
 | Subagents | Read/write the featured `subagentModels` list capped at five ids. `GET/PUT /api/injection-model` manages the shared delegation model/effort selection, the independent OpenCodex guidance switch, and the default-off `syncCodexSubagentDefaults` opt-in for native Codex subagent defaults. When OpenCodex owns the active Codex routing, native `[agents]` defaults apply to newly created Codex tasks after sync/restart; external user-managed provider configs remain untouched. The defaults do not cause delegation and preserve existing user-owned defaults rather than overwriting them. PUT is partial-update: absent keys are unchanged, `null` clears, and non-object bodies are rejected with 400 before field validation. `syncCodexSubagentDefaults: true` requires a nonblank `model` and a supported Codex reasoning effort when effort is set; clearing `model` (null/empty) always clears effort and disables native-default sync even when the stored effort was invalid. |
-| V2 / Multi-agent mode | `GET/PUT /api/v2` — reports/sets the codex `multi_agent_v2` feature flag, the 3-state `multiAgentMode` override (`v1`/`default`/`v2`), the `keepNativeChatGptOnV1` hybrid pin, and the logical maximum thread count. Selecting `v2` normally enables the native flag; with the hybrid pin it disables that global override so native rows can resolve to v1 while routed rows resolve to v2. Selecting `v1` disables the flag; `default` leaves it unchanged. PUT rejects an explicit enabled flag that conflicts with the selected mode or hybrid pin. Every transition preserves the logical thread limit, is rollback-safe, and resyncs the catalog. GET and successful PUT also return stored `multiAgentModeHintText` plus response-only `multiAgentModeHintRecommendation: { text, revision }`; the recommendation is not a writable or persisted config field. Both also return response-only `multiAgentSurfaceAdvisory: { required, mode, recommended, version, docsUrl }`, true while the resolved mode is not v1 and the stored acknowledgement version is behind; PUT accepts `multiAgentSurfaceAdvisoryAcknowledged`, where only `true` stores the current version and `false` is an explicit no-op, and it composes with a `multiAgentMode` write in the same body so the dialog's recommended answer is one request. |

 | Logs & Debug | Reached through the Usage & Logs row’s section switcher (`/#logs`), with two tabs. Logs tab: request/runtime logs for local diagnosis. `LogsFilterBar` owns controls over the shared `LogFilterState`; `filterLogs` composes filters over the loaded ring. The logs envelope adds `generatedAt` (proxy epoch milliseconds); the page advances that sample with monotonic elapsed time and retains a browser-clock fallback for older proxies. Reset returns focus to the stable All surface radio. Provider/model options include attempts, model choices match normalized complete identities, and relative-time filtering refreshes every 30 seconds while the Logs tab is active, independently of network auto-refresh. Debug tab (`/#logs/debug`; legacy `/#debug` deep links redirect there): provider + usage toggles, refresh/follow log viewer. `GET/PUT /api/debug`; `GET /api/debug/logs` and `GET /api/debug/usage-logs` (monotonic `after` cursor, legacy `since` accepted). CLI: `ocx debug provider|usage …` (both streams via running proxy API). |
 | Usage | `GET /api/usage` read-only aggregates of readable rows from `~/.opencodex/usage.jsonl`; the ledger is streamed in fixed 1 MiB chunks, so the former read-byte and parsed-row caps cannot omit its prefix. Oversized skipped rows produce positive `usageIncomplete` metadata. The response includes measured / reported / unreported / unsupported / estimated counts, a daily zero-filled grid, and model and provider breakdowns. `GET /api/usage/timeline` uses the same ledger and canonical attribution helpers for bounded bucketed model series. Never exposes prompts. Fast observations and cost provenance follow the [response-tier authority contract](transports/responses.md#response-tier-observation-authority): the provider editor classifies `responseTierAuthoritative` as an operator-owned boolean under the existing redaction and write boundaries, `src/usage/log.ts` retains it on final outcomes and attempts (old records keep their legacy meaning), and `src/usage/cost.ts` never prices a non-authoritative echo or confirmed label as response-confirmed. |
 | Request metrics | `GET /api/metrics` exposes process-local Prometheus text format v0.0.4 only when `metricsExport.enabled` was true at startup. The ordinary management gate applies; data-plane credentials do not grant access, and disabled mode is 404. `src/server/request-metrics.ts` owns fixed counters/histograms and receives a narrow final-request fact from `src/server/request-log.ts`; `src/server/index/serve-options.ts` creates one owner and injects the recorder and read-only snapshot into the request and management paths. |

+# Subagent Surface And Capacity
+
+Surface and limit settings are independent of [subagent roster ordering](subagents.md).
+
+## Multi-agent surface mode (3-state)
+
+`OcxConfig.multiAgentMode` controls the `multi_agent_version` field stamped on catalog entries:
+
+| Mode | Behavior |
+| --- | --- |
+| `"v1"` | Force ALL entries to `multi_agent_version = "v1"` ??overrides upstream pins (sol/terra included). |
+| `"default"` | Respect upstream model pins (sol/terra=v2, luna=v1, others=null ??codex feature flag decides). On sync, stale forced values are cleared and upstream pins restored. |
+| `"v2"` | Force ALL entries to `multi_agent_version = "v2"` ??overrides upstream pins (luna included). |
+
+The override is applied as a final pass in both `buildCatalogEntries` (live `/v1/models` path) and
+`mergeCatalogEntriesForSync` (on-disk sync), AFTER all normalization and visibility processing. This
+ensures `normalizeRoutedCatalogEntry` (which deletes `multi_agent_version` from routed entries) does
+not clobber the forced value.
+
+A forced pass records each row's pre-override value once, in `opencodex_multi_agent_version_origin`
+(a string pin, or null for none); repeated forced passes never replace it. Returning to `"default"`
+consumes the record. Pristine baseline and native pins still win; the record only decides a native
+row the baseline predates, which previously kept the forced stamp because an absent baseline entry
+cannot tell a stale forced value from a genuine pin (issue 5636). Rows written before the record
+existed keep that non-destructive read.
+
+`getDefaultConfig()` (`src/config/proxy-env.ts`) writes `multiAgentMode: "v1"` explicitly, using the version
+constant from `src/config/multi-agent-surface.ts`, so v1 is the install default while a v2
+native-to-routed child task is undeliverable ciphertext. The repair and salvage merges in
+`src/config/diagnostics.ts` pin `multiAgentMode` and `multiAgentSurfaceAdvisoryVersion` to the stored
+document, because spreading the defaults underneath would repair an unrelated missing field
+into a surface change its operator never made.
+An absent key still means `"default"`, because selecting base deletes the key ??absence cannot be
+read as "never configured". An install that predates that change is therefore not rewritten; it is
+asked once. `multiAgentSurfaceAdvisoryRequired()` is true while the resolved mode is not v1 and
+the stored `multiAgentSurfaceAdvisoryVersion` is below `MULTI_AGENT_SURFACE_ADVISORY_VERSION`, and
+only the operator answering the dashboard notice writes that version.
+
+CLI: `ocx v2 mode v1|default|v2`. GUI: segmented control on the Models page. API: `GET/PUT /api/v2`
+with `multiAgentMode` field.
+
+The `multi_agent_v2` feature flag and the logical maximum thread count are separate from
+`multiAgentMode` (`src/codex/features.ts`): the mode decides which surface Codex advertises, while
+the flag and thread count decide what the native runtime allows.
+Because the global feature has precedence over catalog pins, Codex config injection reconciles it
+to disabled whenever persisted OpenCodex mode explicitly selects v1. This includes a fresh install
+on a Codex home that had previously enabled v2; external-provider ownership and read-only injection
+preflight still prohibit that write. The transition runs inside the same write lock and preimage as
+the rest of injection, so a later refusal rolls the flag back with the files.
+
+`keepNativeChatGptOnV1` makes mode `v2` a catalog-driven hybrid: OpenCodex disables the global
+`multi_agent_v2` override because codex-rs resolves that override before a model row's explicit
+`multi_agent_version`. Native ChatGPT rows then select v1 from the catalog and routed rows select
+v2. An explicit attempt to enable the global flag while the hybrid pin is active is rejected.
+
+### Concurrent child limit
+
+The Models page's Model settings panel exposes one subagent limit control in v1, base and v2,
+including hybrid mode with the global `multi_agent_v2` flag disabled. Its displayed value counts
+children only. Surface selection and capacity are independent; raising the cap neither spawns
+children automatically nor guarantees faster execution.
+
+`GET/PUT /api/v2` retains its existing `maxConcurrentThreadsPerSession` units: with `enabled: false`, N means N
+children; with `enabled: true`, N+1 includes the primary thread. The GUI subtracts one for display
+and adds one on save only when that global flag is enabled. Catalog-selected v2 in hybrid mode
+does not change those API units. An unset limit leaves the default to the native runtime.
+New sessions consume limit changes; a long-running App host may need a normal restart.
+
+`src/codex/features.ts` reads and writes the canonical `[agents].max_concurrent_threads_per_session`
+child limit, falling back to the legacy `max_threads` alias. Equal-valued aliases normalize to
+the canonical key on write; conflicting aliases refuse a write unless an explicit replacement
+limit resolves them. Unsupported or unsafe writes refuse before mutation. With the global v2
+flag disabled, a limit edit updates the canonical child count and removes a stale feature-level
+v2 limit without enabling that flag. These rules establish configuration consistency; they do
+not attest the effective capacity of a running native or routed session.
+CLI and dashboard global-v2 conflict warnings name both supported agents keys.

 `modelAutoCompactTokenLimits: { "gpt-6-astra": 700000 }` lowers the long-window default of 784,800.
 An explicit smaller provider cap or target limit still wins, including native-alias combos.
 
+Without a configured hard limit, the native catalog keeps the advertised `max_context_window`
+separate from the default `context_window` (for Astra, 872,000 versus 272,000). Compaction still
+uses the effective default window. To give one model 500,000 tokens and the others 300,000, set
+`providers.openai.contextWindow` to `300000` and
+`providers.openai.modelContextWindows` to `{ "gpt-6.1-sol": 500000 }`.
+The per-model value overrides the provider window; `providerContextCaps.openai`, when enabled,
+remains a ceiling for every native model and must be at least `500000` for this example.
+Each model's own capacity still bounds the result.
+
 The API row has 1,050,000 context, 922,000 maximum input, 128,000 maximum output, text/image input,
 and API reasoning efforts through `max`. OpenCodex's routed synthetic Ultra control retains its
 existing wire-effort mapping; it is not an additional API effort. There is no Astra `-pro` alias.

+default `context_window`. Only configured hard limits narrow that maximum: the exact model's
+window overrides the provider window, then the provider context cap bounds either. Both paths
+share validation and precedence through `nativeOpenAiConfiguredContextLimit` in
+`src/codex/catalog/metadata.ts`. Strict normalization preserves the maximum for trusted
+account-selector native rows too; ordinary routed rows remain bounded by their effective window.
+Compaction and max input still follow the effective default
+window, including retained lower soft budgets. Native capacity remains defined by the
+[native passthrough contract](catalog.md#native-passthrough). Covered by
+`tests/codex-integration/catalog-native-max-context.test.ts`.

 `forward` uses configured static headers without relaying caller authorization; `key` uses the
 configured provider key.
 
+When history from Google is replayed to canonical ChatGPT Codex or the official OpenAI Responses
+API, the adapter removes item-level `extra_content` from the outgoing HTTP request or WebSocket
+create. Native `/responses/compact` applies the same projection. The original history keeps the Google

 The adapter preserves the incoming client's `User-Agent` as a fallback in both auth modes because
 some Responses-compatible providers use the Codex client fingerprint for compatibility behavior.
 An explicitly configured provider `User-Agent` remains authoritative regardless of header casing;

Subject: [PATCH 29/72] fix(startup): launch the registered Desktop bundle and
 executable (#7137)

* fix(startup): launch Desktop by its registered app bundle path

Launch Desktop from the bundle path recorded in its login registration, with matching installation ownership and fail-closed manual-open guidance. Preserve the app-bundle suffix refusal and explicit ownership fixture types.

Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(startup): bind registered bundle launch to its main executable

Reject relative launch registrations and non-file executable targets. Match
CFBundleExecutable to the canonical registered Desktop binary before opening
the recorded bundle. Exercise the actual macOS plist conversion without
launching an app, and document manual recovery for inconsistent evidence.

* docs(ko): match the registered-bundle reopen condition in the Desktop guide

* docs(ko): keep the Start at Login menu label

* fix(startup): validate LaunchAgent paths with POSIX semantics

Keep the macOS registration contract independent of the test host. Place
fixtures on the caller's drive so Windows relative() cannot return an
absolute cross-drive target, and assert the rejected path is truly relative.
Exercise Windows drive paths and non-macOS command refusal explicitly.

Under Desktop the shim installer child gets the login-shell PATH (`src/server/login-shell-path.ts`); an intact overlay not active on the dashboard's PATH reports `shimActivationPending` and shows the activation step instead of Repair. The Desktop row says "Running · Start at Login not verified" (`desktopBadgeKey` in `gui/src/startup-health-ui.ts`) for a fresh reading of a running owned or supervised app without verified login registration, and "Installed but unhealthy" otherwise; failed or stale readings never get the narrower label. Recovery guidance asks the user to check Start at Login and, when it is already checked, the system's login-item allowance. Compiled startup probes and the dashboard installer child (`runCliInstall` in `src/server/startup-action-control.ts`) use the standalone-aware self-launch argument builder.

Subject: [PATCH 30/72] fix(responses): frame retained compaction requests as
 history (#7138)

* fix(responses): frame retained compaction requests as history

Preserve canonical replay history and original request details while framing retained plaintext requests only in translated and routed provider prompts. Native OpenAI passthrough remains unchanged.

Co-authored-by: Robin Bially <7304732+robin-bially@users.noreply.github.com>

* fix(responses): exclude local compaction from history framing

+## Retained requests after compaction
+
+For translated providers and routed Responses gateways, OpenCodex automatically frames
+plain-text user requests before the latest readable Codex checkpoint as historical context.
+Requests the checkpoint reports as completed should not be repeated; retained text remains
+available for unfinished work within its existing authorization. Later user input takes priority,
+including pauses, cancellations and changes of scope. A checkpoint grants no new permission.
+
+This is enabled by default and needs no setting. Original request text and canonical thread/replay
+history are preserved. Native OpenAI Responses passthrough, summarizer turns, context wrappers,
+images/files and assistant/tool items are unchanged. The framing applies to plaintext checkpoints
+beginning with Codex's summary prefix; decoded OpenCodex checkpoints retain their existing
+continuation guidance. Client-side summarizer turns using Codex's standard compaction prompt
+also bypass framing. Framing is a prompt instruction, so model behavior can vary.

 ## Decoded checkpoint continuation
 
-`src/responses/parser.ts` adds `CHECKPOINT_CONTINUATION_NOTE` from `src/responses/compaction.ts` to the system prompt only when normal generation contains a decoded `ocx1:` checkpoint; `src/adapters/openai-responses/request-strips.ts` applies the same condition to passthrough `instructions` while lowering the checkpoint to a user message. Summarizer turns, opaque native blobs and requests without decoded checkpoints receive no note. `SUMMARY_PREFIX` and checkpoint text remain unchanged, and later user messages retain their order after the checkpoint.
+`src/responses/parser.ts` adds `CHECKPOINT_CONTINUATION_NOTE` from `src/responses/compaction.ts` for decoded `ocx1:` checkpoints; `src/adapters/openai-responses/request-strips.ts` does the same while lowering them. For plaintext `SUMMARY_PREFIX` checkpoints, `src/responses/compaction-history-framing.ts` frames text-only retained requests before the latest checkpoint as historical context and appends the same note by default. The parser projects only adapter context; `src/adapters/openai-responses/passthrough.ts` projects only non-OpenAI-operated outbound bodies. Original request text/blocks, canonical raw history, item identities, replay-prefix lengths, checkpoints and later input remain unchanged. Context wrappers, images/files and assistant/tool items are preserved; summarizer turns and opaque native blobs do not activate framing. Native OpenAI passthrough input is unchanged.
 
 The note is a prompt contract and grants no authority. Completed requests remain history unless a later user message asks to repeat them. Unfinished work continues only under existing authorization and within its scope, without asking for that authorization again while it still applies. Permission and confirmation gates remain authoritative: a pending decision or required permission must resolve before the dependent action. Checkpoints and delegations, including those from another thread, neither grant authority nor expand scope. Later user messages take priority, including pause, cancellation, replacement and scope changes.
 
-The continuation-note and continuation-wire tests establish prompt-contract and wire-construction evidence, including preservation of existing instructions and checkpoint ordering. They do not establish model behavior or whether a model actually resumes the correct task.
+The continuation-note and continuation-wire tests establish prompt and wire contracts. `tests/responses/compaction-history-framing.test.ts` adds offline A/B projection, original-detail preservation, native passthrough isolation, multi-turn canonical replay/dedup coverage and exclusion of client-side summarizer turns ending in the canonical `COMPACT_PROMPT` (which carry no `compaction_trigger`). These tests do not establish live model behavior or whether a model actually resumes the correct task.

 send that thinking and still count it.

+### Native Chat thinking replay
+
+These Chat reasoning lists also apply to native `/v1/chat/completions` tool-call continuation.
+The proxy preserves supplied `reasoning_content` and restores omitted reasoning from upstream
+JSON or SSE responses using tool-call ids. Original reasoning replay requires a stable
+`thread-id`, `session_id`, or `session-id` header on each request and the same provider, endpoint,
+model and credential. The cache is process-local and bounded; a restart, expiry, eviction, or
+missing conversation header uses the configured minimal placeholder instead. A placeholder
+cannot reconstruct lost reasoning. Clients should retain upstream `reasoning_content` in their
+assistant history for reliable resumed conversations.
+
+When `preserveReasoningContentModels` is unset, DeepSeek Flash/Pro model names are recognized
+across versions, including `deepseek-v4.1-flash`, namespaced ids and gateway suffixes. Explicit
+lists remain authoritative: `preserveReasoningContentModels: []` disables automatic repair,
+while `requiresReasoningPlaceholderModels: []` disables placeholders and still allows cached
+original reasoning. Other model families require the preserve declaration.
+Tool-enabled DeepSeek requests also require reasoning on earlier assistant answers without tool
+calls. The configured placeholder fills these omissions; no original reasoning can be recovered
+from the tool-call cache for those turns. Preserve their supplied reasoning for full fidelity.

+
+`src/adapters/openai-chat/reasoning-replay.ts` repairs assistant tool-call history missing
+`reasoning_content` before native serialization. Caller-supplied nonempty text wins. The native
+lane honors the same preserve/placeholder policy as translated Chat; absent preserve declarations
+recognize DeepSeek Flash/Pro families across dotted versions, namespaces and gateway suffixes.
+Explicit preserve lists (including `[]`) remain authoritative, and an explicit placeholder list
+can disable fabricated placeholders while allowing original cached reasoning.
+For tool-enabled DeepSeek requests the configured placeholder also repairs earlier assistant
+answers without tool calls. Those turns have no call-id replay entry; supplied reasoning wins.
+
+`src/server/chat-native-reasoning.ts` records upstream JSON and fragmented SSE reasoning under
+all parallel call ids, separately for each choice. Replay requires a sanitized `thread-id`,
+`session_id` or `session-id` and the existing exact provider/destination/adapter/model/credential
+scope. The native send rebinds that scope before every request build, including key rotation.
+Missing identity, a restarted/expired/evicted cache, and another route receive only the configured
+placeholder; they never recover another conversation's raw text. SSE capture retains at most
+256 KiB and 64 calls within the translator budget and releases on terminal/error/cancellation.
+Unfinished tool streams cannot seed replay. This leaves the native wire and response fields intact.

+## Claude Opus 5.5 progress updates
+
+When the `anthropic` adapter sends Claude Opus 5.5 to `api.anthropic.com` (OAuth or API key),
+OpenCodex requests Anthropic's [progress-update display mode](https://platform.claude.com/docs/en/build-with-claude/thinking#progress-updates).
+Progress updates and mid-turn acknowledgements appear as visible assistant commentary in Codex,
+even when thinking summaries are hidden. Reasoning summaries are omitted in this mode because
+Anthropic cannot distinguish progress updates from reasoning under `display: "summarized"`.
+The original signed thinking blocks are preserved for tool continuation; no signature is decoded
+or rewritten. Updates appear once their signed block completes. Other models and compatible
+third-party endpoints retain their existing thinking display behavior.

 A shared-quota Anthropic 429 or classified pre-output account 403 records the served account's cooldown even when the request has used its allowed retry sends. That final account remains excluded on the next request; combo target cooling for 429 is skipped only after the matching account cooldown is present.

 The Anthropic helper sends share the same routing authority: `getAnthropicSidecarAccessToken` resolves the vision-describe and web-search sidecars' helper model through the same first-match route decision, so a routed send authenticates as the route's own account rather than whatever pool account happens to be active. A strict route with no eligible account fails the helper locally instead of silently falling back to the active outsider, matching the primary-traffic contract; callers without a pool config keep the plain stored-credential path.

+# Anthropic progress updates
+
+`src/adapters/anthropic.ts` selects `thinking: {type: "adaptive", display: "updates"}` with
+`thinking-display-updates-2026-08-18` only for Opus 5.5 on `api.anthropic.com`, for key and OAuth sends.
+`src/types/request.ts` carries the complete signed update on its text-delta event.
+`src/adapters/anthropic-progress.ts` uses this documented display contract to classify nonempty
+thinking text as commentary, buffering one block under the translator budget until its final signature.
+Signatures remain opaque; compatible gateways and other models keep their prior display mode.
+Hidden-summary preferences suppress reasoning, not these user-facing updates.
+Signed history preserves source block order, including thinking between tool calls; unsigned
+cross-provider history retains the adapter's preface-before-tools repair.
+`tests/adapters/anthropic/anthropic-progress-updates.test.ts` exercises SSE/JSON presentation,
+exact replay, mixed block order, OAuth beta preservation and cancellation cleanup.
+
+## Signed Anthropic progress commentary
+
+`src/responses/anthropic-progress.ts` creates an empty-summary reasoning carrier followed by one
+visible `phase: "commentary"` message for a documented Anthropic progress update. Its `ocxr1`
+envelope stores the exact signed text and signature plus `upd`, the following message's ID.
+`src/bridge/sse.ts` and `src/bridge/response-json.ts` preserve this pair even when summaries are hidden.
+Compaction ignores signed progress events: only ordinary summary text enters the checkpoint,
+and neither bridge emits the commentary pair during compaction.
+`src/responses/parser.ts` removes only the adjacent commentary copy with matching ID (or no ID),
+phase and exact text, leaving the original thinking block in source order. Edited copies remain.
+`src/claude/outbound.ts` restores the signed thinking block and consumes the presentation copy on
+both JSON and SSE conversions; ordinary locally hidden envelope text remains undisclosed.
+
+`src/responses/assistant-replay.ts` preserves text, empty signed blocks, signature updates and
+redacted blocks in order for the internal continuation builders in
+`src/server/responses/terminal-guard.ts` and `src/server/responses/advisor-slot.ts`.
+The hosted tool loops in `src/web-search/loop.ts`, `src/web-search/run-turn-loop.ts` and
+`src/images/loop.ts` reconstruct progress events as signed thinking parts. Search's early
+commentary path retains these events for the next iteration.
+Intercepted search and image iterations emit their validated signed progress before fulfilling
+the hosted calls, retaining the same blocks for replay and avoiding duplicate live updates.

Windows Desktop identity is read from `%APPDATA%\com.opencodex.desktop\install-id` and checked against live parentage; Windows Start at Login is unverified and Desktop never receives startup protection credit there. Independent [live Desktop supervision](desktop-shell.md#runtime-ownership-from-the-apps-side) can also grant startup protection without a claim when that app's login registration is verified; it never becomes ownership. On Linux, auto-launch 0.5.0 writes the login entry under HOME/.config/autostart, so a relocated XDG_CONFIG_HOME (outside that search path) is uncredited. Conditional entries and ambiguous Exec syntax are uncredited; the resolved desktop basename must match and its resolved ocx stays in the same directory. Both complete evidence reads must agree on ownership, install-id, entry contents, executable targets, PID and parent relationship; changes fail closed. AppImage registrations are uncredited because they name the outer image rather than the mounted executable. `src/server/startup-health-cache.ts` launches source and compiled probes with `selfLaunchArgv`, revokes stale protection, and preserves desktop recovery guidance. An enabled, identity-matching macOS LaunchAgent registration remains viable when `launchctl print` specifically proves the job is absent in the current session. `src/service/desktop-startup.ts` reports `registered-not-loaded` for next login; wrong plist paths/arguments/label, disabled override, unknown failures and supervisor races still refuse credit. `src/codex/autostart-health.ts` distinguishes this protected registration in restart safety. `src/service/linux-linger.ts` uses bounded `loginctl show-user` to report already-enabled linger, advise activation only when disabled, or explicitly report unavailable diagnosis. `src/cli/ensure-desktop-cold-start.ts` launches a claimed Desktop only on macOS. Its LaunchAgent executable path must be POSIX-absolute, including when the launch probe is exercised on another host; Windows drive paths do not satisfy that plist contract.

Subject: [PATCH 34/72] feat(providers): add DeepSeek Harness authenticated
 account provider (carry #6293) (#7164)

* feat(providers): add DeepSeek Harness authenticated account provider (carry #6293)

Adds `dsh-account`, an OAuth-kind provider that explicitly imports the
grant stored by a signed-in DeepSeek Harness Desktop install and routes
inference to DeepSeek's pinned Anthropic Messages endpoint with
x-dsh-auth-token. The DSH credential file is read only during
`ocx login dsh-account` / dashboard add-account and is never written.
Import requires a verified account ID, refresh is disabled and a 401
marks the account needsReauth, the quota probe returns authoritative
empty quota without deriving percentages from wallet amounts, and the
API-key `deepseek` provider stays a separate credential domain.

Ported from #6293 head 73760bbce onto current dev: redaction keeps dev's
session-token labels and adds x-dsh-auth-token, preset counts are
recounted from the registry (105 total, 85 key, 16 OAuth), and the DSH
invariants move to structure/providers/dsh-account.md to keep
providers-and-adapters.md within its line budget.

Co-authored-by: Flowershangfromthebranches <152056395+Flowershangfromthebranches@users.noreply.github.com>

* docs(dsh-account): name the dashboard Log in action

* fix(dsh-account): pin every model to the DSH adapter

An accepted modelAdapters override (openai-chat / openai-responses) could
switch a dsh-account model to a generic adapter after the account token
was injected as provider.apiKey, which would send it as a Bearer key to
the configured baseUrl and bypass the DSH destination pin. dsh-account
now carries a provider-wide wire pin in src/types/wire.ts, so config load
and management writes reject the override and wire resolution always
returns the dsh-account adapter.

A needsReauth DSH row is also skipped by the account quota probe: its
grant cannot refresh, so the probe could only resend a rejected token.

* fix(dsh-account): keep the account token out of model discovery

Model discovery chose its transport from the row's editable adapter, so a
dsh-account row edited to adapter "cursor" with another baseUrl could
send the account token to that host through Cursor's GetUsableModels.
mayResolveModelsOAuth now refuses dsh-account outright, which covers the
dashboard provider test and every catalog gather, and the registry entry
declares its static catalog (liveModels: false).

A quota 401 now retires the probed credential generation the same way an
inference 401 does; a re-import that landed meanwhile stays usable.

The registry-derived adapter conformance test gets the DSH base URL, since
the adapter correctly refuses the Anthropic fixture host.

* fix(dsh-account): pin the row itself for every helper that spends its token

Anthropic sidecar helpers (web search, vision) and Compatibility Lab probes
resolve OAuth tokens by provider name and send them on their own
transports. A dsh-account row edited onto the anthropic adapter with
another baseUrl could therefore hand the DSH token to a helper that sends
it as a Bearer key to that host, and Lab probes would send even the
canonical row's token to the wrong endpoint and scheme.

credentialPinnedProviderConfigError now rejects, at config load and on
management writes, a dsh-account row whose adapter is not dsh-account or
whose baseUrl leaves https://api.deepseek.com/anthropic. The destination
check moves to src/providers/dsh-account-destination.ts so validation and
the adapter share it. Anthropic helper selection skips the row by name and
Lab refuses it before resolving a token.

* test(adapters): enumerate the dsh-account adapter in the registry authority roster

The registry authority test lists every production adapter exactly once. This branch registers dsh-account, so the roster gains the matching entry.

+`dsh-account` est un fournisseur de compte expérimental à importation prioritaire, conçu pour réutiliser les identifiants de compte authentifiés d'une application DeepSeek Harness (DSH) Desktop installée.
+
+- **Indépendant de la clé d'API DeepSeek :** `dsh-account` utilise le quota de session DeepSeek authentifiée de l'utilisateur (portefeuilles standard et bonus, dépenses totales), tandis que le fournisseur `deepseek` facture sur le solde de la clé d'API de la plateforme. Les deux domaines d'identifiants et de routage sont strictement distincts et ne basculent jamais l'un vers l'autre.
+- **Importation explicite uniquement :** OpenCodeX détecte si DeepSeek Harness est installé et connecté (`~/.dsh/.credentials.yaml`), mais ne copiera, n'importera ni n'utilisera jamais automatiquement le jeton sans une action explicite de l'utilisateur (`ocx login dsh-account` ou clic sur Importer dans le tableau de bord web).
+- **Magasin d'identifiants DSH en lecture seule :** OpenCodeX traite `~/.dsh/.credentials.yaml` comme strictement en lecture seule. OpenCodeX n'écrit, ne modifie, ne supprime ni ne change jamais les permissions des fichiers appartenant à DeepSeek Harness.
+- **Copie d'identifiant et déconnexion isolées :** Lors de l'importation, OpenCodeX valide le jeton auprès du point de terminaison d'identité officiel de DeepSeek (`/auth-api/v0/users/current`) et enregistre sa propre copie dans le magasin d'authentification OpenCodeX. Se déconnecter ou supprimer le compte dans OpenCodeX supprime uniquement la copie locale d'OpenCodeX ; cela ne déclenche jamais de déconnexion de session distante et ne vous déconnecte pas de DeepSeek Harness Desktop.
+- **Pas de rotation automatique en arrière-plan et réimportation en cas de 401 :** Les autorisations de session DSH ne disposent pas d'un point de terminaison d'actualisation automatique en arrière-plan. Si le serveur distant renvoie HTTP 401 (`ACCOUNT_TOKEN_INVALID`), OpenCodeX marque le compte comme `needsReauth` et interrompt le routage. Pour rétablir l'accès, l'utilisateur doit réimporter explicitement via `ocx login dsh-account`.
+- **Avertissement relatif aux tiers :** OpenCodeX ne revendique aucune approbation ni autorisation officielle de DeepSeek pour la réutilisation des autorisations de session par des clients tiers.

 Google Antigravity groups a model's complete `low` / `medium` / `high` variants into one entry with an effort selector. This includes Claude Opus and Sonnet 5.5 and future versions discovered during automatic refresh. Partial sets remain separate. Existing enabled/disabled choices carry into the grouped entry; genuinely new models still follow your New model policy. Saved suffix IDs continue to request their original tier. Grouped effort routing survives a proxy restart when model discovery is temporarily unavailable. A running Codex session may need to reload its model list after catalog refresh.

 The native dashboard choices are add-only and do not sign out `kiro-cli`. A device dialog shows the code and verification destination. Only recognized Kiro or Builder ID hosts are opened as links; an unexpected destination is shown as copyable text for review. Closing the dialog sends cancellation and leaves a bounded background status check to reconcile a commit already in progress. A stalled status response is retried; exhausting the flow deadline produces the neutral ended outcome rather than claiming success. Google and GitHub approval completes when Kiro reports `authorized` (or the legacy `approved` status) with valid tokens and a profile ARN.
 The account list marks Kiro accounts excluded from automatic selection with a reason, when available.
 
+### DeepSeek Account (DSH)
+
+`dsh-account` is an experimental, import-first account provider designed to reuse the authenticated account credentials of an installed DeepSeek Harness (DSH) Desktop application.
+
+- **Independent from DeepSeek API Key:** `dsh-account` runs on the DeepSeek account signed in to DeepSeek Harness, whereas the `deepseek` provider bills against your platform API key balance. The two credential domains and routes are strictly separate and never fall through into one another.
+- **Explicit import only:** opencodex reads `~/.dsh/.credentials.yaml` (or `$DSH_HOME/.credentials.yaml`) only when you run `ocx login dsh-account` or select **Log in** on the DeepSeek Account (DSH) row of the dashboard's **Add provider** picker. It never copies, imports, or uses the token on its own.
+- **Read-only DSH credential store:** OpenCodeX treats `~/.dsh/.credentials.yaml` as strictly read-only. OpenCodeX never writes, modifies, removes, or alters the permissions of any files belonging to DeepSeek Harness.
+- **Isolated credential copy & logout:** Upon import, OpenCodeX validates the token against DeepSeek's authoritative identity endpoint (`/auth-api/v0/users/current`) and saves its own copy to the OpenCodeX auth store. Logging out or removing the account in OpenCodeX only deletes the OpenCodeX local copy; it never triggers upstream remote session logout and will not sign you out of DeepSeek Harness Desktop.
+- **No background token rotation & 401 re-import:** DSH session grants do not feature an automatic background refresh endpoint. If upstream returns HTTP 401 (`ACCOUNT_TOKEN_INVALID`), OpenCodeX marks the account `needsReauth` and halts routing. To restore access, the user must explicitly re-import via `ocx login dsh-account`.
+- **Third-party disclaimer:** OpenCodeX makes no claim of official endorsement or authorization by DeepSeek for third-party clients reusing session grants.

+- **Независимость от API-ключа DeepSeek:** `dsh-account` использует квоту авторизованной сессии DeepSeek пользователя (баланс обычного/бонусного кошельков и общие расходы), тогда как провайдер `deepseek` списывает средства с баланса API-ключа платформы. Эти два домена учётных данных и маршрутизации строго разделены и никогда не переключаются друг на друга.
+- **Только явный импорт:** OpenCodeX определяет наличие установленного и авторизованного DeepSeek Harness (`~/.dsh/.credentials.yaml`), но никогда не копирует, не импортирует и не использует токен автоматически без явного действия пользователя (`ocx login dsh-account` или нажатия кнопки «Импорт» в веб-дашборде).
+- **Хранилище учётных данных DSH только для чтения:** OpenCodeX обращается с `~/.dsh/.credentials.yaml` исключительно в режиме только для чтения. OpenCodeX никогда не записывает, не изменяет, не удаляет файлы и не меняет права доступа к файлам DeepSeek Harness.
+- **Изолированная копия учётных данных и выход:** При импорте OpenCodeX проверяет токен через официальный эндпоинт идентификации DeepSeek (`/auth-api/v0/users/current`) и сохраняет собственную копию в хранилище аутентификации OpenCodeX. Выход из системы или удаление аккаунта в OpenCodeX удаляет только локальную копию OpenCodeX; это никогда не вызывает завершение удалённой сессии и не приводит к выходу из DeepSeek Harness Desktop.
+- **Без фонового обновления токена и повторный импорт при 401:** Разрешения сессий DSH не поддерживают эндпоинт автоматического фонового обновления. Если апстрим возвращает HTTP 401 (`ACCOUNT_TOKEN_INVALID`), OpenCodeX помечает аккаунт как `needsReauth` и прекращает маршрутизацию. Для восстановления доступа пользователь должен выполнить явный повторный импорт через `ocx login dsh-account`.

+
+`dsh-account` 是一个实验性的、优先导入已有凭据的账户提供商，用于复用已安装并登录的 DeepSeek Harness (DSH) Desktop 应用程序的认证凭据。
+
+- **独立于 DeepSeek API Key**：`dsh-account` 使用用户的 DeepSeek 认证会话配额（普通/赠送钱包余额与总消费），而 `deepseek` 提供商按平台的 API Key 余额扣费。这两个凭据体系和路由严格隔离，互不回退。
+- **仅显式导入**：OpenCodeX 会检测是否已安装 DeepSeek Harness 且已登录（`~/.dsh/.credentials.yaml`），但绝不会在没有用户明确操作（`ocx login dsh-account` 或在 Web 仪表盘点击导入）的情况下自动复制、导入或使用该令牌。
+- **对 DSH 凭据库只读**：OpenCodeX 将 `~/.dsh/.credentials.yaml` 视为严格只读。OpenCodeX 绝不写入、修改、删除或更改任何属于 DeepSeek Harness 的文件权限。
+- **隔离的凭据副本与登出**：导入后，OpenCodeX 会通过 DeepSeek 权威身份端点（`/auth-api/v0/users/current`）校验令牌，并在 OpenCodeX 认证库中保存独立副本。在 OpenCodeX 中登出或删除该账户仅会删除 OpenCodeX 本地副本，绝不会触发上游远程会话登出，也不会退出 DeepSeek Harness Desktop。
+- **无后台令牌自动刷新与 401 重新导入**：DSH 会话授权不支持自动后台刷新端点。若上游返回 HTTP 401（`ACCOUNT_TOKEN_INVALID`），OpenCodeX 将该账户标记为 `needsReauth` 并停止路由。要恢复访问，用户必须通过 `ocx login dsh-account` 显式重新导入。
+- **第三方免责声明**：OpenCodeX 不主张 DeepSeek 官方对于第三方客户端复用会话授权提供背书或支持。

+# DeepSeek Harness Account Provider
+
+`dsh-account` reuses the DeepSeek account signed in to DeepSeek Harness (DSH) Desktop. It is an OAuth-kind provider with its own credential domain; it shares no key, route or fallback with the API-key `deepseek` provider.
+
+## Import
+
+`src/oauth/dsh.ts` reads `$DSH_HOME/.credentials.yaml` (default `~/.dsh/.credentials.yaml`) only inside `loginDshAccount`, which runs on `ocx login dsh-account` or the dashboard's **Log in** action for the provider. Nothing else reads the file, and nothing in opencodex writes, deletes or changes the permissions of it. The `deepseek-account-platform/default` grant record is validated against `https://platform.deepseek.com/auth-api/v0/users/current` with manual redirects before anything is stored.
+
+Only a successful business response with a nonempty authoritative account ID imports. A missing ID fails closed; email, phone and display name never supply a slot identity, so two DSH accounts sharing an email land in different slots and reauthentication uses the shared account-ID comparison in `src/oauth/index.ts`. Parser and transport failures surface fixed error codes instead of credential or profile fragments.
+
+The imported copy lives in the opencodex credential store. Removing the account deletes only that copy and never signs DSH Desktop out.
+
+## Refresh and 401
+
+DSH grants have no rotation endpoint. `defaultRefreshPolicy` is `disabled`, and `refreshDshAccountToken` never re-reads the DSH file: it throws a terminal "revoked" error. An upstream 401 on the replay path therefore marks the account `needsReauth`; the user re-imports explicitly.
+
+## Destinations
+
+`src/adapters/dsh-account.ts` sends inference only to `https://api.deepseek.com/anthropic/v1/messages`, resolved by `src/providers/dsh-account-destination.ts`. A configured `baseUrl` on another scheme, host or path fails the request before any send.
+
+Every helper that resolves the token does so by the provider name `dsh-account`, so the row itself is pinned: `credentialPinnedProviderConfigError` in `src/config/provider-validation.ts` rejects, at config load and on management writes, a `dsh-account` row whose adapter is not `dsh-account` or whose `baseUrl` leaves that endpoint. Anthropic sidecar helper selection in `src/sidecar/auth.ts` skips the row by name as well, and Compatibility Lab probes refuse it before resolving a token, because the generic probe transport would use another endpoint and auth scheme. Configured headers cannot set `x-dsh-auth-token`, `anthropic-version`, `authorization`, `x-api-key` or `host`; the adapter strips API-key and Claude Code headers and sets the account token last. `src/types/wire.ts` pins every `dsh-account` model to this adapter regardless of `baseUrl` or the row's own `adapter`, so config load and management writes reject a `modelAdapters` override and wire resolution cannot hand the token to a generic adapter that would send it as a Bearer key. The shared executor's manual redirect policy keeps the token from following a redirect. The catalog is static (`liveModels: false`), and `src/oauth/model-discovery-auth.ts` refuses to resolve the DSH token for any model-discovery path, so a row edited to a discovery-capable adapter such as `cursor` still sends nothing. Local plugin upstream rewriters see every provider send, credentials included, by design; that trust covers this provider like any other. `x-dsh-auth-token` is in the redaction key and header-label lists in `src/lib/redact.ts`.
+
+## Quota
+
+`src/providers/quota/dsh-account.ts` probes `https://platform.deepseek.com/api/v0/users/get_user_summary` with manual redirects. A 401 is a terminal quota failure that also marks the probed credential generation `needsReauth` (a re-import that landed meanwhile stays usable), and a `needsReauth` DSH row is not probed at all, since its grant cannot refresh. A successful business response with summary data returns authoritative empty quota: the platform reports wallet amounts with no capacity, so no percentage window is derived from them.

Subject: [PATCH 35/72] feat(claude-cli): stable conversation replay and
 capture-only client tools (carry #6566) (#7165)

Replay each message as a byte-stable text block (current input formatted like its later
history form, canonical tool schemas and arguments, whole-message history checkpoints), so
repeated Claude Code turns keep a stable prefix for the CLI's own prompt cache.

A request that carries tools now gets the shared capture-only MCP bridge: built-in tools and
other MCP servers stay disabled, --allowedTools lists only the selected catalog, and the
captured call returns to the client for approval and execution. Native installs under
~/.local/bin are found when a service PATH misses them.

Carried from #6566 (source head e5b367a6d) by @foodcel.

 - **System prompt:** the caller's system and developer prompts replace the Claude Code preset
   (`--system-prompt-file`), so the turn answers the client's contract rather than the harness
   persona. The folded prompt is staged in a private per-turn file (mode `0600`) and passed by path,
   because process arguments are world-readable through process listing; a request that carries
-  neither a system nor a developer prompt gets an empty file, which replaces the preset with nothing.
-- **Tool ownership:** v1 is text and reasoning only, exactly like the CodeBuddy and Qoder presets:
-  with no tool channel, approval, sandboxing and execution stay with the client. The shared
-  capture-only tool bridge is the documented follow-up.

+- **Conversation caching:** each message is replayed as a separate stable text block, with the

+  only at whole-message checkpoints. Tool catalogs serialize deterministically. Claude Code
+  controls cache breakpoints, so this makes prompt-cache reuse possible without guaranteeing it.
+- **Tool ownership:** when the request carries tools, an isolated capture-only MCP catalog exposes
+  only the client's selected tools (the same bridge CodeBuddy uses). The CLI captures the call and
+  the turn ends there; approval, sandboxing, execution and the returned result stay with Codex,
+  Pi, or another client. Built-in tools and every other MCP server remain disabled.
 - **Destination:** the canonical row names `https://api.anthropic.com` because that is where the
   subscription's traffic lands. OpenCodex never sends that request itself, and overriding the base
   URL fails closed rather than handing the turn to another environment.

+# Claude CLI Replay
+
+`src/adapters/claude-cli/stable-replay.ts` supplies a Claude-only replay builder to the shared `src/adapters/coding-agent/turn.ts` runner through its `conversationInput` slot; CodeBuddy and Qoder keep the default projection. It emits one legal user frame with an immutable text block per message, using identical formatting for a current message and its later history form. History is trimmed at whole-message checkpoints. Developer messages remain in the system prompt; the cut skips orphan historical results and retains a current result's originating call. Checkpoints are at most 20k characters apart; the cut can also discard the boundary message and any leading orphan tool-result blocks. The soft cap counts history characters, excluding the current input and truncation notice; retaining the current tool group's originating call can exceed it.
+
+Canonicalization accepts only plain JSON, preserves arrays/literal values, and sorts object keys, including schema object keys and historical tool arguments. Instruction changes intentionally invalidate that prefix. Tools and schema object keys serialize deterministically, preserving catalog membership, MCP aliases, tool choice, and array order. Object-key sorting intentionally changes model-visible property order while preserving JSON values; integer-like keys follow JavaScript's numeric-key ordering. Invalid non-JSON history supplied by an internal caller fails at the runner's stdin projection as a 502, after launch, and the owned child is terminated. Ordinary HTTP JSON requests cannot carry cycles, accessors or undefined properties.
+
+## Tool capture
+
+A request that carries tools gets the shared capture-only MCP bridge (`src/adapters/codebuddy/tool-bridge.ts` and its server). `--tools ""` and `--strict-mcp-config` stay on, `--allowedTools` lists only the exact `mcp__opencodex__*` names of the selected catalog, and `tool_choice: none` advertises nothing. The runner returns the first assistant tool batch to the client and terminates the CLI at `message_stop`; the MCP handler never executes a call. Historical tool calls are replayed under the MCP names advertised in the current turn. With `acceptWireToolNames`, a tool_use that names an exact selected wire tool is accepted as that tool; the alias is output-only and never enters `--allowedTools`, and any other name ends the turn with `undeclared_tool_call`.
+
+Claude Code controls actual cache breakpoints, so stable replay alone is not a measured savings claim. `tests/providers/claude-cli-efficiency.test.ts` checks replay stability against the legacy negative control, checkpoint behavior, catalog ordering and instruction authority; `tests/providers/claude-cli-tool-capture.test.ts` and `tests/providers/claude-cli-client-http.test.ts` cover capture ownership through the adapter and through real Responses and Chat Completions requests.

Subject: [PATCH 36/72] feat(claude-cli): refuse launches when the Claude
 subscription is exhausted (carry #6566) (#7166)

* feat(claude-cli): stable conversation replay and capture-only client tools (carry #6566)

Replay each message as a byte-stable text block (current input formatted like its later
history form, canonical tool schemas and arguments, whole-message history checkpoints), so
repeated Claude Code turns keep a stable prefix for the CLI's own prompt cache.

A request that carries tools now gets the shared capture-only MCP bridge: built-in tools and
other MCP servers stay disabled, --allowedTools lists only the selected catalog, and the
captured call returns to the client for approval and execution. Native installs under
~/.local/bin are found when a service PATH misses them.

Carried from #6566 (source head e5b367a6d) by @foodcel.

* feat(claude-cli): refuse launches when the Claude subscription is exhausted (carry #6566)

Before a claude-cli launch, check the local Claude Code subscription quota through Anthropic's
usage endpoint. An exhausted 5-hour, weekly or in-scope model window returns 429
claude_subscription_cooldown with Retry-After from the Responses executor (before headers) and
from the adapter, instead of a CLI turn that fails as a generic 502. A reset the CLI itself
reports is remembered until that time.

The check reads the CLI's own sign-in in memory (Keychain without blocking the event loop),
caches identity and quota for a minute under OPENCODEX_HOME (percentages, reset times and a
hashed account key only), fails open on every error, never reads the real sign-in from a test
process, and hands the web-search sidecar's probe lease back on refusal or failure.
CLAUDE_CONFIG_DIR is forwarded to the child so the CLI and the check read one profile.

Carried from #6566 (source head e5b367a6d) by @foodcel.

* test(claude-cli): keep the usage-admission cache case inside a home it creates

The real-home write guard scan rejects removing a path inside a home the test did not create. The case now points OPENCODEX_HOME at its own temporary home, checks the cache lands there, and cleans up only that directory.

Child-internal retries/tool turns are not separately counted; reported actual usage settles in full, including amounts above the seed estimate.

 A request that carries tools gets the shared capture-only MCP bridge (`src/adapters/codebuddy/tool-bridge.ts` and its server). `--tools ""` and `--strict-mcp-config` stay on, `--allowedTools` lists only the exact `mcp__opencodex__*` names of the selected catalog, and `tool_choice: none` advertises nothing. The runner returns the first assistant tool batch to the client and terminates the CLI at `message_stop`; the MCP handler never executes a call. Historical tool calls are replayed under the MCP names advertised in the current turn. With `acceptWireToolNames`, a tool_use that names an exact selected wire tool is accepted as that tool; the alias is output-only and never enters `--allowedTools`, and any other name ends the turn with `undeclared_tool_call`.
 
 Claude Code controls actual cache breakpoints, so stable replay alone is not a measured savings claim. `tests/providers/claude-cli-efficiency.test.ts` checks replay stability against the legacy negative control, checkpoint behavior, catalog ordering and instruction authority; `tests/providers/claude-cli-tool-capture.test.ts` and `tests/providers/claude-cli-client-http.test.ts` cover capture ownership through the adapter and through real Responses and Chat Completions requests.
+
+## Usage admission
+
+`src/adapters/claude-cli/usage-admission.ts` gates every `claude-cli` launch on the local Claude Code subscription quota. The adapter checks it before spawning the CLI, and the Responses executor checks it before dispatch so an exhausted plan returns 429 `claude_subscription_cooldown` with `Retry-After` instead of a generic 502; Chat Completions keeps that code. Admission and cache invalidation share one window selection (plan windows plus custom windows in scope for the requested model family) and one `>= 100` threshold, so an expired window of another family never forces a re-read. A limit the CLI itself reports with a parseable reset ("resets 3pm (Zone)") is remembered until that time.
+
+A probe re-reads the account before it commits: an account switch mid-probe discards the answer (`unknown`, nothing persisted), and the newest refusal is merged at commit time with no await between that read and the write, so a CLI-reported reset is never overwritten. The file has one writer per `OPENCODEX_HOME`, the same single-owner topology as the spend ledger. The check reads the CLI's own sign-in in memory (`detectClaudeCodeTokenAsync`: Keychain without blocking the event loop, or `<CLAUDE_CONFIG_DIR>/.credentials.json`), caches the resolved identity for one minute, and sends the access token only to Anthropic's usage endpoint through `src/providers/claude-cli-usage.ts`, the same reader the account-pool quota probe uses. `CLAUDE_CONFIG_DIR` is passed to the child so the CLI and the check read one profile. The cache file `<OPENCODEX_HOME>/claude-usage-admission.json` stores only percentages, reset times and a hashed identity key. Every failure (no sign-in, malformed credential, unreachable endpoint) fails open as `unknown`, and a test process (`OCX_TEST_HOME_GUARD`) never resolves the real sign-in. If the executor's check throws or refuses, it releases the web-search sidecar's probe lease first; `tests/responses/responses-claude-preflight-lease.test.ts` and `tests/providers/claude-cli-usage-admission.test.ts` cover both.

Subject: [PATCH 37/72] feat(oauth): code-display login mode for hosts with no
 reachable localhost (carry #6239) (#7170)

* feat(oauth): code-display login mode for hosts with no reachable localhost (carry #6239)

Anthropic's code-display redirect lets a login complete from a container or
remote host: the user approves in any browser and pastes the displayed
code#state, and no callback port is bound. POST /api/oauth/login accepts
mode:"code" and returns a flowId and expiresAt; POST /api/oauth/login/code
answers with the token-exchange outcome for a code flow. Login flow state
is keyed by flow id so concurrent code logins stay separate, with a
10-minute paste window and a 64-row per-provider cap. The CLI spelling is
`ocx login <provider> --headless`.

Carried onto current dev from #6239 (head 0192c2e4b). Changes from the
source: code mode is wired through the shared anthropicOAuthDefinition so
anthropic and anthropic2 both support it; the CLI flag is --headless
because --code carries a secret value elsewhere in the CLI and its operand
is scrubbed from stderr; a code flow is single-use once a paste reaches
the token exchange.

Co-authored-by: Vadym O. <11277453+vadymhimself@users.noreply.github.com>

* fix(oauth): answer code-flow pastes with the flow's own account and keep flow ids scoped

Independent review fixes for the carried code-display login:
- the paste route reports the account this flow persisted, and a flow
  cleared during its exchange answers no_pending_login instead of success
- a flowId is honoured only for a code flow of the same provider, in both
  the paste route and getLoginStatus, so only single-use code flows hold
  a waiting request
- a paste that races the start is refused instead of spending the flow
- ocx login --headless prints only fixed text on failure, never the
  provider error body

Co-authored-by: Vadym O. <11277453+vadymhimself@users.noreply.github.com>

* fix(oauth): take a code flow's account from the store write receipt

Matching the returned refresh token against the account set missed the row
when a concurrent login for the same account rotated the token before the
earlier flow settled, so that flow answered without its account.
saveCredential now returns the write receipt it already produced, and
runLogin reports the persisted account id to startLoginFlow.

Co-authored-by: Vadym O. <11277453+vadymhimself@users.noreply.github.com>

* fix(oauth): report a reauth's account only when its row was written

saveAccountCredential resolves false when the account vanished before the
queued write, and runLogin reports the persisted account only after a real
write. Test stubs of saveCredential now return the write receipt.

 Device-code providers never open a browser from the proxy in either case: they show a code and a
 verification URL to open wherever you are signed in.
 
+### Headless Claude login (code-display mode)
+
+For Anthropic there is a cleaner path than pasting a dead redirect: the **code-display** login.
+Anthropic redirects to its own page and shows a `code#state` string instead of calling back to the
+proxy, so nothing needs to reach `127.0.0.1` on the proxy's host.
+
+```bash
+ocx login anthropic --headless
+```
+
+Over the management API, start with `POST /api/oauth/login` and `{"provider":"anthropic","mode":"code"}`;
+the response carries a `flowId` and an `expiresAt` (10 minutes). Submit the pasted string to
+`POST /api/oauth/login/code` with that `flowId`. The answer is the result of the token exchange —
+`{"ok":true,"account":…}` or `{"ok":false,"error":…}` — so a hosted caller with a single paste box
+knows whether the login actually worked. A paste with the wrong state, or with no code in it, is
+refused before any token request and leaves the flow open for another try; a paste that reaches the
+token exchange uses the flow up, so start a new login if that exchange fails.
+
+Only `anthropic` and `anthropic2` support this mode; other providers answer `code_mode_unsupported`. Several code
+logins can be in flight at once, each pinned to its `flowId`, but they all write the same account
+store: the most recent successful one becomes the active Claude account. This is meant for one
+operator on a headless host, not for isolating unrelated users on a shared instance.

+`--headless` runs the **code-display** login for hosts whose browser cannot reach the proxy's loopback
+callback (containers, remote servers). The command prints an authorization URL; approve it in any
+browser, and the provider shows a `code#state` string to paste back at the prompt. No callback port
+is bound and no browser is launched. Only `anthropic` and `anthropic2` support it today; any other provider exits
+with the list of providers that do. For Codex accounts use the device-code login instead,
+`ocx account login codex --device` — `ocx login codex --headless` is refused rather than passed on.
+The paste window is 10 minutes, and each login accepts one code: if the exchange fails, start a new login. A successful login becomes the provider's active account, exactly
+like a browser login.

+  `src/oauth/index.ts`); today that is `anthropic` and `anthropic2`, which share one OAuth client
+  (`https://platform.claude.com/oauth/code/callback`, set in
+  `src/oauth/anthropic-oauth-definitions.ts`). Any other provider is refused with
+  `400 {"error":"code_mode_unsupported"}`. The Codex spellings of `ocx login` (`codex`, `openai`,
+  `chatgpt`) refuse `--headless` and point at `ocx account login codex --device`
+  (`src/cli/dispatch.ts`). The flag is not called `--code` because that name carries a secret value
+  elsewhere in the CLI and `src/cli/secret-args.ts` scrubs the word after it from stderr.
+- **Flow identity and ownership.** A code-mode start returns `{ mode: "code", flowId, expiresAt }`.
+  Flows are keyed by `flowId` in `src/oauth/login-flow-state.ts`, so several code logins for one
+  provider can be in flight at once; a callback-mode flow still serialises per provider. Every
+  lookup is provider-scoped (`loginFlowKeys` matches `(state.provider ?? key) === provider`), so
+  status, cancellation, clearing and the admission cap never see another provider's flows. A
+  cancel naming a `flowId` that belongs to a different provider is refused.
+- **Expiry and limits.** A code flow's paste window is `CODE_LOGIN_TTL_MS` (10 minutes); an expired
+  flow is reaped as `no_pending_login` the next time that provider starts a login. At most
+  `MAX_LOGIN_FLOWS_PER_PROVIDER` (64) rows per provider are kept; settled rows are evicted first
+  and a flow still in progress is never evicted.
+- **Paste contract.** `POST /api/oauth/login/code` with a `flowId` (or while the provider's newest
+  flow is code-mode) answers with the **outcome of the token exchange**, not merely acceptance:
+  `{ ok: true, account }` or `{ ok: false, error }` where `error` is one of `state_mismatch`,
+  `invalid_or_expired_code`, `no_pending_login` (409), `provider_unreachable`, `malformed_input`.
+  `account` is the row this flow wrote (recorded when it settles), which need not be the active
+  account; a flow cleared or dropped while its exchange runs answers `no_pending_login`. A
+  `flowId` that is not a code flow of the named provider answers `no_pending_login` without
+  waiting, so only a single-use code flow ever holds a waiting request.
+  A paste rejected before the exchange (state, shape) leaves the flow alive for another attempt,
+  as does one that races the start before the flow's state is registered.
+  A code flow is single-use after that: once a paste is handed to the token exchange, further
+  pastes answer `no_pending_login`, and a failed exchange settles the flow. `provider_unreachable` is reserved
+  for a network failure (`TimeoutError`/`AbortError`, or a fetch `TypeError` carrying a `code`);
+  any other error falls to `invalid_or_expired_code`, with the original message kept on the flow.
+  Without a `flowId` and with no code-mode flow, the legacy accept-only contract is unchanged.
+- **Status.** `GET /api/oauth/status` reports the provider's newest flow, including `mode` for a
+  code flow. An explicit flow id is honoured only for its own provider. A caller running several flows tracks each one through its own paste response.
+- **Account store semantics: single operator.** A successful code login writes the same credential
+  store as any other login, and the store has one active account per provider. Two concurrent code
+  logins that both succeed leave the **later** one active. This is a single-operator convenience
+  for headless hosts, **not** tenant isolation: do not use it to host several unrelated users on
+  one instance.
+
+Tests: `tests/oauth/oauth-code-login.test.ts` (flow keying, cross-provider isolation, error
+classification, paste contract) and the `--headless` cases in `tests/cli/cli-provider.test.ts`.

 Turn on the CLI switch in Connect → Claude, or run `ocx claude config set --first-party on`; use `off` to disable it. The switch is immediate and refuses `{enabled:false, cliFirstParty:true}` before any field is saved; it may also refuse to turn on if the local intercept is unavailable, the CA cannot be prepared, settings cannot be read, or a foreign proxy setting owns the keys. Off persists even when the intercept is unavailable; disabling Claude routing alone leaves an owned settings env untouched. For fully native terminal traffic with only Desktop first-party on, set `NO_PROXY='*'` in the shell. This still carries the first-party account risk stated above.
 Disabling Claude routing leaves the owned settings env untouched. While the bound listener still runs, every Messages request relays unchanged; after it stops, plain `claude` cannot connect until OpenCodex runs or Desktop/CLI first-party is turned off. Native `ocx claude` sets `NO_PROXY=*` only for an owned env without a foreign inherited `HTTPS_PROXY`/`https_proxy`. With a foreign proxy it preserves that value and warns that the settings-owned intercept still applies; turn Desktop/CLI first-party off or unset the setting.
-The UI distinguishes uncertainty about whether settings still point at its proxy (unknown), a token-bearing opencodex proxy with a foreign CA (foreign: fix HTTPS_PROXY / NODE_EXTRA_CA_CERTS manually), and a tokenless loopback proxy beside a foreign CA (local: ownership is unconfirmed; remove HTTPS_PROXY if unused). With matching applied settings and a bound listener but Claude routing off, disabled means requests relay unchanged while it is bound; turn first-party off to remove settings. An owned URL with no listener is stopped; a bound listener with an owned CA but mismatched port or token is broken even when routing is off. With an intent on, stopped or broken plus ineligible interception displays routingOff: Claude routing or the intercept is off, or this machine is a client of another opencodex hub; enable interception on this machine or turn first-party off to remove the settings. When interception is stopped, use **Start interception** or `ocx claude intercept start` to retry within the running OpenCodex service. Saving first-party settings also starts it automatically. A refusal reports disabled routing, client role, an ephemeral public port, an occupied port, or a startup failure. For an occupied port, free it or set `claudeCode.intercept.port`. If a pair is already bound on a different port, the response names both ports; use the bound port or restore the configured value. CLI intent with no proxy is not applied; one intent with a live proxy gets the shared-relay notice; any remaining proxy with neither intent is residual, unless unknown, foreign, or local takes precedence.

 Claude Code reaches the pair through an authenticated `HTTPS_PROXY` URL plus `NODE_EXTRA_CA_CERTS` in its settings env
 (`src/claude/intercept/settings.ts`), so no `ANTHROPIC_BASE_URL` rewrite is involved and the client
 still believes it talks to Anthropic. The proxy splices `CONNECT api.anthropic.com:443` onto the TLS
-listener, relays every other CONNECT target blind, and refuses unauthenticated clients, plain proxied HTTP (a 405 whose body names the NO_PROXY fix), and loopback targets. Because it can never serve loopback, the same env carries a `NO_PROXY` loopback bypass (`127.0.0.1,localhost,::1,0.0.0.0`); without it Claude Code sent local HTTP MCP traffic to the proxy and every such server failed (#6936). Apply appends only the missing entries to a user value and leaves a covering value (including `*`) alone; an owned block without the bypass classifies stale so the startup migrate repairs it, and a non-string value other than null is refused as `foreign_env` rather than rewritten. Because the key is shared, apply records `{ hadKey, previous, written }` in `<claudeConfigDir>/opencodex-no-proxy.json` (`src/claude/intercept/settings-no-proxy.ts`, no token), and removal restores `previous` only while NO_PROXY still equals `written`, preserving anything else. Restoration needs that receipt: one that could not be written leaves none, and removal then keeps the appended entries (the harmless direction); a removal whose settings write fails before committing tries to put the receipt back. The receipt lives exactly as long as its ownership episode: an apply from an absent block and every removal invalidate it first and fail closed (`unreadable`) when they cannot, and rollback restores it with the captured value. The per-install proxy token is stored owner-only under `<OPENCODEX_HOME>/claude-intercept/` (0600 plus a real per-user NTFS ACL on Windows, via `src/lib/windows-secret-acl.ts`, and re-pinned on every read-through `ensure`), and the settings file carrying it is written through the same hardened atomic writer. Every start runs `migrateClaudeInterceptSettings` (`src/claude/intercept/settings.ts`), which rewrites an owned env that no longer matches — e.g. a pre-auth URL left by an upgrade — while never creating an absent env or touching a foreign one, so a service restart cannot strand clients on 407s. Status/inspection reads the token without minting it; only apply and intercept startup create it.

Because it can never serve loopback, the same env carries a `NO_PROXY` loopback bypass (`127.0.0.1,localhost,::1,0.0.0.0`); without it Claude Code sent local HTTP MCP traffic to the proxy and every such server failed (#6936). Apply appends only the missing entries to a user value and leaves a covering value (including `*`) alone; an owned block without the bypass classifies stale so the startup migrate repairs it, and a non-string value other than null is refused as `foreign_env` rather than rewritten. Because the key is shared, apply records `{ hadKey, previous, written }` in `<claudeConfigDir>/opencodex-no-proxy.json` (`src/claude/intercept/settings-no-proxy.ts`, no token), and removal restores `previous` only while NO_PROXY still equals `written`, preserving anything else. Restoration needs that receipt: one that could not be written leaves none, and removal then keeps the appended entries (the harmless direction); a removal whose settings write fails before committing tries to put the receipt back. The receipt lives exactly as long as its ownership episode: an apply from an absent block and every removal invalidate it first and fail closed (`unreadable`) when they cannot, and rollback restores it with the captured value. The per-install proxy token is stored owner-only under `<OPENCODEX_HOME>/claude-intercept/` (0600 plus a real per-user NTFS ACL on Windows, via `src/lib/windows-secret-acl.ts`, and re-pinned on every read-through `ensure`), and the settings file carrying it is written through the same hardened atomic writer. After a successful CONNECT bind, startup runs `migrateClaudeInterceptSettings` (`src/claude/intercept/settings.ts`), which rewrites an owned env that no longer matches — e.g. a pre-auth URL left by an upgrade — while never creating an absent env or touching a foreign one, so a service restart cannot strand clients on 407s. Migration uses the bound handle's port; a failed bind leaves settings bytes unchanged. `StartServerDeps.startClaudeInterceptProxy` forwards the runtime binder seam through `src/server/index/optional-listeners.ts`, letting tests bind real proxies on port 0 without probe-and-release races while production retains stable ports. Status/inspection reads the token without minting it; only apply and intercept startup create it.
 The TLS listener rewrites `POST /v1/messages` and `POST /v1/messages/count_tokens` to a loopback origin and dispatches them under the `claude-intercept` ingress; other paths relay to the configured upstream. One relayed path is extended: for the standalone CLI's picker catalog, the listener's `cliCatalog` hook (`src/claude/intercept/cli-catalog.ts`) merges opencodex rows into `GET /api/organizations/<org>/model_selector/cc` (or `/api/model_selector/cc`), touching only the `cc` surface and leaving Desktop's `ccd`/`code` surfaces to picker mode, and into the fallback `additional_model_options` of `GET /api/claude_cli/bootstrap`. Eligibility: the `cc` catalog is rewritten only for a CLI-classified `User-Agent` with `claudeCode.cliFirstParty` on, because Claude Code caches it on disk for every process and a Desktop-spawned process must not seed rows a plain `claude` cannot route; the bootstrap request carries no entrypoint and follows CLI intent alone. Rows come from `buildCliPickerModels` (`src/claude/intercept/picker-models.ts`), which uses Desktop 3P registry aliases because the CLI offers only Claude-shaped ids (an `ocx-claude-*` row renders "Update Claude Code"), and advertises only an alias the registry decodes back to the same route. `src/claude/intercept/cli-picker.ts` supplies them lazily on the first eligible request, persists the snapshot at `<OPENCODEX_HOME>/claude-intercept/cli-picker-models.json`, re-checks each persisted row against the live registry (its alias must still decode to its recorded route; a cold registry after a restart is awaited first, and a snapshot whose rows still do not decode, for example after a provider change, is rebuilt within the same bound), and bounds a cold build at 2.5 s while awaiting the shared registry build in `src/claude/desktop-3p-startup.ts` that startup also uses (a failed or empty on-demand build is not retried for 30 s). Both CLI catalogs obey the shared [picker rewrite bounds](clients/claude-desktop.md#picker-catalog-rewrite-bounds), preflighting row growth before copying and keeping the final JSON within 16 MiB. The rewrite fails open: a provider error, non-2xx status, unparsable body, or no added row relays the upstream bytes unchanged; a body over the 16 MiB cap is cut off while streaming and answered 502 rather than buffered. Claude Code trusts its cached `<claudeConfigDir>/cache/model-catalog/*-cc.json` for about an hour, so `writeSettings` in `src/claude/intercept/settings.ts` and every successful `reconcileClaudeFirstPartySettings` drop those files (leaving Desktop's `*-ccd.json`); running sessions keep their list until restarted.
 The pair is on by default on a hub (`claudeCode.intercept.enabled`); its proxy port defaults to public port + 100 (`claudeCode.intercept.port`). The lifecycle records bind failure, and stop joins both sockets. Its serialized `ensure()` joins pending startup, reuses the live config and dispatch wrapper, and can start a previously unbound pair. `stop()` refuses future ensure calls and awaits an in-flight start. Local management applies and `ocx claude intercept start` (`POST /api/claude-intercept/start`) use this seam through `src/server/index/optional-listeners.ts`; hub-management ingress and data-plane credentials cannot start interception. Status reports `interceptReason` (with `interceptFailurePort` for a CONNECT bind failure) and optional `pickerReason` (with `pickerFailurePort` when the Desktop picker relay port is occupied), distinguishing disabled routing, client role, ephemeral public ports, occupied CONNECT ports and other failures. A changed configured port never rebinds a running pair: apply reports `port_mismatch` with both ports. With an ephemeral public port (`startServer(0)`), an explicit intercept port is required. The lifecycle makes a best-effort legacy picker-key cleanup attempt before checking client role, disabled routing/interception, or an ephemeral public port. Each new unbound lifecycle `ensure()` attempt retries cleanup; management requests rejected before that seam do not invoke it. Cleanup failures do not change the eligibility result or block startup. Direct `startClaudeIntercept` callers retain the same cleanup defense. Mock-only regression coverage lives in `tests/claude-integration/claude-intercept-cleanup.test.ts`.
 This ingress honours first-party model bindings (`claudeCode.intercept.modelMap`); see [Claude Desktop](clients/claude-desktop.md#first-party-model-bindings). Picker mode and the primitive's optional `allowedTargets` restriction are described under [Desktop egress proxy](clients/claude-desktop.md#picker-mode-the-desktop-egress-proxy). The macOS picker reuses an exportable signing identity protected by the OS credential store across normal restarts, without a plaintext key in the config directory. Restore verifies the constrained CA and current OS trust without installing trust; explicit picker `on` or `trust` grants missing or revoked trust. Legacy migration cleanup may still require consent, and native keychain unlock or application-access prompts are separate. Windows and Linux start no picker CA, credential-store or proxy work; the main intercept pair and best-effort legacy-key cleanup remain available.

Subject: [PATCH 41/72] fix(oauth): bound refresh consumers and retain stale
 owners (carry #7117) (#7136)

* fix(oauth): bound refresh consumers and preserve retryable capacity

Bound unresolved OAuth refresh consumers while preserving stale-flight ownership evidence across refused replacement admission. Report retryable capacity separately from authentication failures, and preserve cancellation priority and lease-release assertions.

(cherry picked from commit b722d746f10dafb7eeea2aabcf8b94aec6a6a5db)

* fix(oauth): retire stale owners before admitting replacements

Keep stale registry ownership through definitive-result cleanup and durable retirement regardless of spare consumer capacity. Recheck the installed flight when concurrent replacements resume.

Co-authored-by: Epinephrine <luvs01@hanmail.net>

* fix(responses): preserve cancellation at refresh capacity

Observe both independent cancellation signals at initial refresh refusal and document retry behavior for OAuth capacity.

Co-authored-by: Epinephrine <luvs01@hanmail.net>

* fix(responses): link both client signals through runTurn recovery

Address the hosted Codex P2: request-only cancellation takes priority during refresh refusal, including committed SSE. Remove both listeners on cleanup.

Co-authored-by: Epinephrine <luvs01@hanmail.net>

* fix(oauth): report deferred refresh retirement without identity

Address the CodeRabbit observability finding with one bounded diagnostic per retained flight, a closed failure reason, and no account or credential fields.

Co-authored-by: Epinephrine <luvs01@hanmail.net>

* refactor(oauth): move refresh-flight retirement into its own module

Pure move of retireSettledOAuthRefreshFlight, the refresh-waiter gate and OAuthRefreshFlightEvidence out of src/oauth/index.ts, so this branch merged with current dev stays under the 2000-line file-size ratchet. The registry map is passed explicitly; behavior is unchanged.

+## OAuth refresh capacity reached
+
+If a Responses request reports `OAuth token refresh capacity reached`, wait at
+least one second before retrying. The proxy limits pending OAuth refresh work
+to 256 consumers per process, including requests waiting on the same refresh.
+A disconnected request keeps its refresh reservation until that work settles;
+requests using fresh cached credentials can still proceed.
+
+Before a response starts, this temporary refusal returns HTTP 503 with
+`Retry-After: 1`. A stream that has already started instead ends with a server
+error. Capacity refusal does not mark the account as needing reauthentication,
+so signing in again is unnecessary for this error. A refresh that never settles
+can continue occupying capacity; the limit does not impose a refresh deadline.

 Catalog HTTP acquisition follows the [proxy-routing contract](catalog.md#remote-catalog-http-proxy-routing). CLI model lists expose shared catalog estimates as `price`; `models price` retains the saved override in `cost` and adds `effectiveCost`. Explicit zero overrides win; unknown prices remain null, and automatic defaults are never persisted to `modelCosts`. Covered by `tests/cli/cli-models.test.ts` and `tests/cli/cli-models-price.test.ts`. Ordinary model discovery, startup sync, and explicit sync apply the [new-arrival catalog contract](catalog.md#shared-catalog) before publishing rows. The scoped persisted decision also updates the live config merge baseline, so subsequent visibility writes preserve manual re-enablement. A file-loaded inventory that already differs from disk can publish HTTP rows through a detached policy projection without adding unsaved live disables; retained catalog writes still refuse stale inventory, and its load provenance follows the [config contract](config.md).
 
-OAuth refresh coordination follows the [refresh-lock identity contract](catalog.md#accounts-namespaces-and-pool-rotation): a fresh unreadable lock remains held, and release requires matching descriptor identity. A failed path-identity probe preserves the refresh callback outcome. Cooperating lock metadata changes serialize through the existing SQLite mutation transaction; release keeps the descriptor open through identity comparison and any unlink, then closes it. Failed metadata writes remove only a matching owned path after successful coordination; unknown identity, failed probes or unavailable coordination retain the path for stale recovery. Async refresh work holds no metadata transaction.
+OAuth refresh resolution in `src/oauth/index.ts` admits at most 256 pending consumers across the process, including callers joining an existing refresh. The separate 32-flight ceiling remains. Consumers retain their admission until the shared promise settles, even if their client already cancelled; fresh credential snapshots do not take this admission. Exhaustion raises the existing retryable, account-free refresh-capacity error, and initial Responses preparation and upstream-401 forced-refresh consumers answer 503 with a short Retry-After before response commitment; cancellation takes priority. An already-committed runTurn stream emits retryable capacity rather than an authentication failure. Stale owners are aborted even under waiter pressure; rejected admission retains their registry evidence, and admitted replacements wait for settlement and durable retirement before taking the registry slot. Post-dispatch uncertainty remains retryable without replay or false reauthentication; pre-dispatch intent can be cleared exactly. Retirement IO failure retains the bounded slot for a later retry, including after a backward clock adjustment. Deferred durable retirement logs once per flight with a closed reason and provider only; no account or credential identity is emitted. Retirement waits for definitive provider-result cleanup, preserving late successful rotation or explicit rejection. This bounds pending resolution count, not request bytes, refresh duration, or arbitrary cancelled work. The release-on-cancel turn contract is unchanged. `tests/oauth/oauth-refresh-generic-lock.test.ts` covers cancelled consumers, rejection cleanup and cached credentials under pressure. `tests/oauth/oauth-refresh-stale-capacity.test.ts` covers saturated and unsaturated stale-owner retirement and late settlement; transport coverage is in `tests/responses/responses-oauth-refresh-capacity.test.ts`. OAuth refresh coordination follows the [refresh-lock identity contract](catalog.md#accounts-namespaces-and-pool-rotation): a fresh unreadable lock remains held, and release requires matching descriptor identity. A failed path-identity probe preserves the refresh callback outcome. Cooperating lock metadata changes serialize through the existing SQLite mutation transaction; release keeps the descriptor open through identity comparison and any unlink, then closes it. Failed metadata writes remove only a matching owned path after successful coordination; unknown identity, failed probes or unavailable coordination retain the path for stale recovery. Async refresh work holds no metadata transaction.
 
 The configuration-only [plaintext V2 contract](subagents.md#plaintext-v2-agent-messages)
 is scoped to canonical ChatGPT Responses forwarding; other source-area behavior described here is unchanged. Cursor's localized native-shell names follow the [routing-commentary guard contract](providers/cursor.md#cursor-native-exec).

 `src/server/responses/run-turn-execution.ts` handles a structured pre-output 401 for `isOAuth401ReplayProvider` runTurn routes with one generation-fenced forced refresh and an `auth-recovery` hop. A terminal refresh may admit a surviving account; otherwise the client gets the login instruction. Devin quota `permission_denied` (429) and plain permission denial (403) do not trigger this path.
 An `oauth`-source Devin key rejected with 401 needs reauthentication because Cognition has no refresh endpoint. A `local-cli` slot with a stored account ID or email can adopt a changed CLI key after host and bounded identity validation; [OAuth/Devin ownership](../providers-and-adapters.md) defines the locked store check across aliases. An identity-less CLI import instead needs an explicit `ocx login devin` after rotation. Unreadable files and transient probes leave the account unflagged. A pause during refresh returns 403 without retry, reauth, or replacing the stored key. Kiro's terminal alternate requires `OAuthLoginRequiredError`; transient refresh failures do not enter it.
-Tests: `tests/responses/responses-devin-401-replay.test.ts` and `tests/server/server-kiro-refusal-e2e.test.ts`.
+Forced-refresh capacity exhaustion on adapter, passthrough and runTurn paths is a local retryable refusal: before response commitment it returns 503 with Retry-After: 1, and cancellation from either the request signal or the option signal wins with 499. The runTurn controller links and cleans up both signals. It does not rotate an account or require login. A runTurn readiness heartbeat that already committed SSE leaves HTTP 200 in place but emits a retryable server-error capacity event without the rejected credential's authentication code. Tests: `tests/responses/responses-devin-401-replay.test.ts`, `tests/responses/responses-oauth-refresh-capacity.test.ts` and `tests/server/server-kiro-refusal-e2e.test.ts`.

+# Meta Muse login
+
+Meta Muse management login in `src/server/management/oauth-account-routes.ts` requires a
+server-resolved `gui-session` before starting credential acquisition, including local import,
+device login, add-account and reauthentication. This principal is not a checkbox receipt;
+forged GUI headers and raw management credentials do not substitute for it. Direct CLI login
+and other OAuth providers retain their existing policies. `src/oauth/meta-muse-device.ts`
+cancels unparsed authorization/mint failures, including mint429, without reflecting their bodies.
+`src/oauth/meta-muse-keychain.ts` reads the measured macOS service/account through `/usr/bin/security`
+with a cancellable 120-second approval deadline. The importer publishes a dashboard hint before waiting,
+reaps the prompt on timeout/cancellation, and distinguishes missing, denied, interaction-disallowed
+and unknown failures without retaining stderr. `src/oauth/meta-muse-errors.ts` provides fixed
+reason-based import/validation diagnostics; public error projection reconstructs those messages
+from their kind and bounded HTTP status, never mutable messages, OS errors or credential text.
+Invalid pointer/secret JSON shapes are refused before property access. Import failures keep
+the existing credential and offer explicit key paste recovery when available, without silently
+initiating a second login. Import and paste validation use `x-api-version: 1.0.0` and reject redirects.
+Management discovery and changing device/manual instructions follow the
+[OAuth continuation contract](../gui-and-management-api.md#oauth-login-continuations); discovery
+filters the current principal without changing the direct CLI roster or relaxing login admission.
+
+`src/oauth/meta-muse.ts` imports only the verified macOS pointer/Keychain shape.
+Successful import takes precedence over device login; add-account and reauthentication
+skip import. Missing local identity falls through to device login. Existing but unreadable
+credentials never trigger an automatic grant: an explicit paste may recover the login.
+Neither the OAuth account token nor an imported email is reused by a manual-key recovery.
+`src/oauth/login-cli.ts` prints instruction-only hints without announcing or launching a browser.
+
+`tests/providers/meta-muse-keychain.test.ts` exercises the subprocess deadline and cleanup
+without invoking the real Keychain. `tests/oauth/oauth-meta-muse-login-diagnostics.test.ts`
+covers public projection, shape refusals, cancellation and explicit paste recovery.

Subject: [PATCH 43/72] feat(oauth): pin generic pool conversations to
 request-local accounts (#7150)

* refactor(oauth): share conversation identity extraction

* feat(oauth): retain generic pool conversation affinity through recovery

Keep automatic affinity-mode choices request-local while preserving the operator selection revision and credential generation fences. Rebind admitted recovery accounts, retain configured new-session strategies, and bound process-local ownership by home, provider and caller. Refs #3375.

It requires `pool.kernel` and proactive preference; other strategies retain their existing rules. `reset-first` also requires `pool.kernel`: among eligible accounts that are not exhausted, the first attempt (while the proactive preference is on) and a 429 rotation both prefer the account whose quota resets soonest (the weekly window when one is reported, otherwise the 5-hour window), with more headroom breaking ties.

-Deliberately narrower than `anthropicAccountPool`: no session affinity, no quota-ranked

+Set `providers.<name>.oauthAccountFailover.sessionAffinity` to `"conversation"` together with
+`enabled: true` to keep a conversation on its admitted account. Session identity uses the client
+thread marker, session headers, thread header, then `prompt_cache_key`; a shared Desktop cache
+cohort is excluded. Bindings are isolated by provider, configuration home and authenticated caller
+principal. Unauthenticated local callers share the local scope. No session marker means no binding.
+
+New sessions use the existing strategy (`pool.kernel` still gates round-robin/fill-first).
+Existing sessions stay pinned even when another account has more quota. A pause, reauthentication
+requirement, family cooldown or incompatible model roster releases the binding; existing bounded
+failure recovery binds the admitted replacement. Kiro's concurrency cap still waits or refuses
+rather than moving a healthy bound conversation merely to balance load.
+
+In this mode automatic choices, including unkeyed requests and failovers, stay request-local:
+the dashboard's selected account remains the operator's selection. Request history still attributes
+the serving account. Manual selection, same-account reselection and roster/policy revision changes
+invalidate provider bindings, including writes from another process. An ordinary refresh keeps the
+same account. Fill-first retains its current account in memory without changing the saved selection.
+Bindings expire after 24 hours without admission, are bounded to 2,000 entries process-wide
+(including fill-first cursors), and are lost on restart. Set `sessionAffinity: "none"` or disable
+proactive preference to release them. Codex and Anthropic retain their own affinity contracts.
 
 The Codex pool and the Anthropic pool are excluded and keep their own rotation; enabling this
 changes neither. A provider with a single stored account is a strict no-op, and no cooldown is

 A shared-quota Anthropic 429 or classified pre-output account 403 records the served account's cooldown even when the request has used its allowed retry sends.

Exact revoked-token 401s persist generation-fenced reauthentication under [the Anthropic recovery contract](providers/anthropic-account-pool.md#revoked-oauth-access-token-recovery).
 
 The Anthropic helper sends share the same routing authority: `getAnthropicSidecarAccessToken` resolves the vision-describe and web-search sidecars' helper model through the same first-match route decision, so a routed send authenticates as the route's own account rather than whatever pool account happens to be active. A strict route with no eligible account fails the helper locally instead of silently falling back to the active outsider, matching the primary-traffic contract; callers without a pool config keep the plain stored-credential path.

+# Generic OAuth Account Pool
+
+## Conversation affinity
+
+`src/oauth/generic-session-affinity.ts` owns opt-in generic-pool conversation bindings. Provider-local
+`oauthAccountFailover.sessionAffinity: "conversation"` requires proactive enablement; it does not
+change reactive failover activation. Bindings are scoped to configuration home, provider and caller
+principal, store only a hashed session key, account ID and selection receipt, and expire after 24 idle
+hours within a process-wide 2,000-entry bound. Pause, reauth, model/family ineligibility and persisted
+selection-revision changes release them. Cross-process revisions are checked on every lookup.
+`src/oauth/session-affinity-key.ts` supplies the existing client-thread/header/cache-key precedence
+for both generic and Anthropic callers; shared Desktop cache cohorts do not establish identity.
+
+`src/server/responses/request-transport.ts` admits every automatic generic affinity-mode choice
+without persisting an active-account change, including new/unkeyed sessions and failovers. The
+operator's saved selection/revision fences queued sends independently of each conversation's serving
+snapshot and credential generation. An unchanged selection with a renewed credential re-resolves
+that same account; a changed selection follows the operator. Off-active 401 refresh remains bound
+to the sent account. Admitted replacements rebind; affinity hits do not advance round-robin.
+Fill-first has a bounded process-local cursor and prefers below-threshold alternatives without
+moving the persisted selection. Kiro capacity retains wait/refusal semantics. Codex and Anthropic
+are excluded. `tests/oauth/generic-session-affinity.test.ts` and
+`tests/server/server-generic-oauth-affinity.test.ts` exercise these boundaries with synthetic accounts.
+
+`src/types/provider.ts` declares the optional `sessionAffinity` mode; omission keeps existing behavior.

 pool entries (#7144)

* feat(codex): preserve the signed-in identity as pool fallback

* fix(codex): retain preservation evidence across conflicting observations

* fix(codex): report signed-in quota use independently of policy state

+### `ocx account preserve-signed-in openai [on|off|status] [--apply-to-bound] [--json]`
+
+Opt in to **use other eligible accounts first and keep the signed-in ChatGPT/Codex Desktop
+identity as fallback**. A bare invocation or `status` reads the running proxy's policy, affected
+entry IDs, manual pin and next unbound choice. `on` persists `codexPreserveSignedInAccount: true`;
+`off` restores your existing custom account order without rewriting any priorities.
+
+The reserved group includes native `__main__` and ordinary pool entries with the same selected
+ChatGPT account/workspace **and** normalized member email. Sharing a workspace alone is insufficient.
+The group follows the latest physical login observed by the proxy's native-login lifecycle;
+no incoming request credential can define it. If member/workspace evidence is unavailable,
+`identityKnown: false` reports that only main can be identified. Status obtains a fresh owned
+observation; a busy or unreadable native profile returns 503 without applying the change.
+
+All four Codex strategies prefer other identities with quota headroom, preserving custom order
+within each group. Reserved entries remain fallback when preferred tiers drain. **Fallback can
+consume the signed-in quota**, subject to existing model access, pause, cooldown, reauthentication,
+hard-lock and paid-credit consent checks. This policy does not grant paid-credit consent.
+
+Healthy existing bindings stay in place, and manual pins and exact account-qualified model routes
+override the preference. To apply it to ongoing work, run:
+
+```bash
+ocx account preserve-signed-in openai on --apply-to-bound
+```
+
+This explicitly releases only affected bindings and any affected manual pin for the **next request**;
+in-flight requests keep their captured account. Unrelated bindings and pins remain. Moving work may
+lose its warm prompt cache, and account-scoped uploads or continuation state can prevent a move.
+`codexAccountPriorityFailback` remains a separate opt-in, with its existing quota-strategy,
+positive-threshold and fresh-observation conditions; it can also move work toward a preferred group.
+
+For **never use this identity through the pool**, use `ocx account pause openai main` instead:
+linked pause excludes main and matching pool entries without changing the desktop login file.
+Only requests that reach OpenCodex are controlled. This does not unlock an already-disabled
+desktop composer or promise to fix client-side quota gating.

 Reads or sets one Codex pool account's selection order: **higher is used earlier**, the default is
 `0`, and the range is `-100` through `100`. Only the `openai` Codex pool is ordered, so other

+account. `ocx account priority openai main last` lowers only that entry; use
+`preserve-signed-in` above to reserve its matching ordinary pool entries too.
 
 Preset words stand in for small integers: `first` is `+2`, `earlier` is `+1`, `normal` is `0`,
 `later` is `-1`, and `last` is `-2`. `reset` returns the account to the default and drops its stored

 | `activeCodexAccountId?` | `string` | — | Manually selected Pool account for the next request. Selection clears thread affinity; in-flight requests keep captured credentials. |
 | `codexAccountPriorities?` | `Record<string, number>` | — | Per-account selection order for the Codex pool: account id → integer from `-100` to `100`, **higher is used earlier**, absent means `0`. This is an ordering boundary, not an eligibility one: selection narrows the already-eligible accounts to the highest tier that still has quota headroom, and `accountPoolStrategy` then picks within that tier. A tier is skipped only when every member is at or above its own nonzero effective usage threshold (account override or global default), cooling down, soft-avoided, paused, or needs reauthentication — unknown quota never drains a tier. Ordering never makes an ineligible account selectable and by default, never re-binds a thread that already has an account. The main `__main__` account participates on equal terms, which is how the Codex Desktop login can be set to drain last. With no entries the pool behaves exactly as before. A malformed map is ignored with a console warning (ordering off, no config repair). Managed by `ocx account priority` and the Codex Auth page. |
 | `activeCodexAccountPinned?` | `string` | — | Account id the operator last selected by hand. While set, a higher `codexAccountPriorities` tier cannot preempt it until the pin is released by drain, exclusion, deletion, or an explicit failover/promotion away. Ordinary round-robin movement inside the capped tier does not release it. Writing any `codexAccountPriorities` entry also releases the pin, so a pin made before an order existed cannot outrank one set afterward. `GET /api/codex-auth/active` reports both whether the effective account is pinned (`pinned`) and the account carrying the ceiling (`pinnedAccountId`). |

Existing custom priorities are preserved inside each group. Healthy bindings and manual pins remain; exact account routes and Direct mode are unchanged. Fallback may consume signed-in quota under all existing guards. Use [account preserve-signed-in](/reference/cli/providers-accounts/#ocx-account-preserve-signed-in-openai-onoffstatus---apply-to-bound---json) for status or an explicit next-request binding transition. |
 | `codexAccountPriorityFailback?` | `boolean` | `false` | Opt-in return of ongoing Codex Pool tasks to a usable higher-priority account under the `quota` strategy. Requests trigger a background quota refresh at most once every five minutes, including failed refresh attempts. When recent quota observations show headroom, the next request may rebind even if its current account is below the threshold. This explicit preference can discard a warm prompt cache; it does not change default cache affinity. No requests means no polling. Manual pins, model access, cooldowns, pauses and reauthentication exclusions still apply; in-flight requests keep their captured account. Requires the current source account's effective threshold to be positive (an override of 0 disables it; a positive override works with global 0); exact account routes and Direct mode are unchanged. |
 | `autoSwitchThreshold?` | `number` | `80` | Usage threshold for placing new/unbound work. `quota` can re-evaluate unbound tasks on their next request once usage crosses this threshold. Bound tasks keep their account past the threshold by default (`pool.cacheAffinity`); they leave only when that account is exhausted or otherwise cannot serve, and then only for an account with genuine quota headroom and strictly lower usage. Set `pool.cacheAffinity: false` to re-evaluate bound tasks at this threshold, still only onto such a destination. `fill-first` uses it only as the drain point for unbound assignment; normal `round-robin` selection does not use it. The score uses the hottest known 5h, weekly, or 30d quota window. `0` disables usage-based proactive switching only, not unbound assignment or failure recovery. |
 | `codexAccountAutoSwitchThresholds?` | `Record<string, number>` | — | Per-account overrides for `autoSwitchThreshold`: account id → integer from `0` to `100`. An absent entry inherits the global value; `0` disables usage-driven switching only when that account is the source. `quota` uses the current source account's effective threshold for bound-task re-evaluation and unbound switching. Fill-first drain and selection-order tier headroom are evaluated against each account's own effective threshold; main-account pins and subagent fallback also use the relevant account's effective threshold. Supports the main `__main__` account. A malformed map is ignored with a warning. Managed by each account card on the Codex Auth page; disabling an override removes its entry. Enabling the override copies the current global threshold into a fixed account value. The override, including `0`, takes precedence over later global changes. Disabling it sends `threshold: null`, removes the entry, and restores inheritance of the current global threshold and future global changes. |

+# Preserve Signed-In Codex Quota
+
+`codexPreserveSignedInAccount` defaults off. `src/codex/account-preservation.ts` gives native main
+and matching ordinary pool entries a lower effective priority band; stored per-ID priorities
+remain unchanged inside each band. Eligibility, model evidence, quota headroom, manual pin ceilings
+and every strategy still use the shared selection path. Unbound quota preemption compares these
+same effective priorities; healthy bindings remain unless existing priority-failback rules apply.
+Exact account routes bypass the preference. Fallback may spend reserved quota, never bypassing
+pause, reauth, model access, hard lock or paid-credit consent.
+
+`src/codex/signed-in-identity.ts` requires matching selected workspace and normalized member email.
+Its process-local observation is published by existing physical-login lifecycle reads and the
+owned linked-group read; request routing reads only memory, even during native profile drain.
+Unknown/conflicting evidence never links a new ordinary row; transient failures and conflicting claims retain the last verified observation. Startup seeds the observation; later
+owned observations follow login changes, and confirmed transitions clear stale observations.
+Pool replacements are matched from their current credentials. Existing lifecycle transitions
+purge main bindings. No credential or member identity is persisted by the policy.
+
+`src/codex/auth-api/account-preservation.ts` exposes GET/PUT policy status under native-main
+ownership and reports affected entry IDs and the actual unbound preview. A validated PUT saves
+before releasing runtime state. Explicit application releases affected affinity scopes and manual
+preference/pin only for subsequent requests; already-materialized requests retain their account.
+The CLI (`src/cli/account-preservation.ts`) drives this API; linked pause remains the absolute
+exclusion alternative.

Subject: [PATCH 45/72] fix(gui): fold Advisor into the Subagents row and
 collapse its notices (#7196)

Advisor no longer takes a sidebar row. It joins Subagents as a section-switcher member, the same pattern Usage & Logs uses, and keeps its #advisor route. The three cost and data-sharing warnings fold into one collapsed disclosure; the consent checkbox and its required notice stay visible.

Claude has no sub-tabs; it shows the Claude Code settings directly. Claude Desktop is a separate Connect tab at `#claude/desktop`. Connect has no section switcher. **Usage & Logs** opens Usage and groups Usage, Logs & Debug, and Storage with a pill-shaped section switcher. The last row, **Remote Link**, groups Remote Link (`#remote`) and Remote Workspace (`#remote-workspace`, when available) with the same switcher. **Codex** is the renamed **Codex Set** row; the preserved URLs include `#codex-set`, `#claude`, `#claude/code`, and `#claude/desktop`; the former `#claude/settings` bookmark opens Code. The former `#claude/account` bookmark redirects to `#providers?provider=anthropic&tab=accounts`. Startup (`#startup`) stays outside the sidebar.

-On the dashboard **Advisor** page, choose the expert model from the catalog selector. It saves the exact catalog identifier, including native, provider, account-qualified, custom and combo selectors. Disabled models and models awaiting initial selection are not offered as new choices. A saved identifier missing from the selectable catalog remains visible with a warning and is preserved until you choose another model or clear it. Catalog loading failures preserve the selection and provide Retry. Choose a model that can return text advice: the catalog does not guarantee consultation compatibility.

Subject: [PATCH 46/72] feat(vertex): accept credential JSON with secure marker
 lifecycle (carry #6843) (#7139)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat(vertex): accept pasted GCP credential JSON in the API-key slot (#6821)

Let the provider's API-key field take a Service Account JSON directly:

- gcp-adc: a `gcp-sa:<account>` marker resolves the credential from the OS
  keychain (same service + entry factory as `keychain:` references) and runs
  the existing service_account JWT / authorized_user flow. The marker sits
  above GOOGLE_APPLICATION_CREDENTIALS in the source priority; everything
  downstream (token cache, refresh skew, in-flight dedup) is untouched.
- api-keys: addProviderApiKey detects a pasted credential JSON (single,
  pretty-printed, or comma-separated for future pool rotation), verifies the
  "type" field, stores the secret in the OS keychain with a read-back check,
  and persists only the marker to config. File paths are rejected with
  paste guidance; unrecognized types are rejected before anything is stored.
- router: usableResolvedApiKey registers the active `gcp-sa:` marker with
  the ADC resolver, so a marker in any pool entry becomes the active source.
- adapters/google: vertex's API-key fast path skips `gcp-sa:` markers —
  they are not API-key material and must reach the ADC branch instead.

Markers keep resolveProviderApiKey synchronous (no signature changes) and
work naturally with the existing 429 key-pool failover: each pool entry can
independently hold a raw key, an ${ENV} ref, a keychain: ref, or a gcp-sa:
marker, and per-key cooldown rotation applies unchanged.

Closes #6821 (partially — live model discovery for vertex mode is a
separate discussion).

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(vertex): pass the marker account per request; review fixes (#6842)

Address CodeRabbit findings:

- gcp-adc: remove the process-global activeMarkerAccount/registration
  (a module-level marker would race across concurrent requests for
  different providers and could resolve one call with another provider's
  credential). The marker account now travels per request via
  getVertexAccessToken(options.markerAccount) and flows through
  currentAdcSourceKey/loadAdcCredentials as an argument. The reconcile
  sweep passes no marker (no request context) — marker entries are
  pruned by expiry instead.
- adapters/google: pass gcpCredentialMarkerAccount(provider.apiKey)
  per request. router: drop the registration; the routed provider
  config carries the marker verbatim.
- api-keys: delete a just-written keychain entry ONLY when the write
  created it — on a failed commit, an upsert must keep the credential
  the previous reference still names.
- tests: narrow the adapter assertion to the ADC-shaped request (URL +
  Bearer header + no x-goog-api-key, with a stubbed fetch), and
  isolate the marker-source tests from host ADC state (empty
  CLOUDSDK_CONFIG, no GOOGLE_APPLICATION_CREDENTIALS, 404 fetch stub).

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(vertex): preserve the marker through routing; harden paste handling (#6842)

Address CodeRabbit round-2 findings:

- router: usableResolvedApiKey returns gcp-sa: marker values UNCHANGED —
  replacing a marker with undefined (it resolves to no key material) would
  silently drop it from the routed config and send the vertex adapter to
  host ADC instead of the configured service account.
- api-keys: storeGcpCredentialJson takes existedBefore and deletes the
  keychain entry after a read-back mismatch only when the entry did not
  exist before the write — a re-paste targets an account an existing
  marker already names, and deleting it would destroy the live credential.
- api-keys: splitCredentialPaste honors the parseGcpCredentialJson contract
  (a single-line brace-leading literal is never eaten — it falls back to a
  plain key row), tracks JSON string/escape state in the brace scanner (a
  } inside a string field no longer splits early), and rejects
  non-separator content before/between objects instead of discarding it.
- tests: router-level pass-through test (routedProviderConfig preserves
  the marker), end-to-end test (routed config feeds buildRequest, ADC
  branch wins), literal-key fallback + gap-rejection tests. Markers keep
  resolveProviderApiKey synchronous.

* docs: attest review readiness checklist (4/4 ticked)

* docs: attest readiness 4/4; trigger gate re-evaluation

* fix(gcp-adc): suppress the GOOGLE_CLOUD_API_KEY fallback for named markers; strict paste validation (#6842)

Address Prana review findings:

- adapters/google: a `gcp-sa:` marker means the operator named ONE credential
  explicitly — the GOOGLE_CLOUD_API_KEY env fallback no longer fires. Without
  this guard, a marker + env key would silently route the provider's inference
  through the ambient env key instead of the configured service account.
- providers/api-keys (capture): a parseable JSON object with an unrecognized
  "type" field (e.g. external_account) is REJECTED with guidance, not saved as
  a plaintext literal key — saving it would send it to the wire verbatim.
  Non-JSON brace values ({abc:def}) keep their key-compat behavior.
- providers/api-keys (tail): content after the LAST object's close up to EOF
  is validated like the mid-gaps — trailing garbage is rejected, not silently
  kept. (Covers captureTrailing otherwise.)

Registrations: per-finding regression tests added (explicit-credential-wins
for markers, JSON-with-unknown-type rejection, tail-gap rejection).

Reject wrapped or malformed credential material before literal persistence or restore, and prevent keychain aliases exposing GCP JSON as wire keys. Revalidate marker readability before cached-token use. Capture deletion candidates and persist CLI/management removal under one mutation lock, preserving post-commit shared-reference cleanup. Cover mixed SA/key failover and DTO redaction with synthetic credentials.

* fix(vertex): classify JSON-escaped credentials before alias resolution

Decode structured JSON before credential classification so escaped field and type names cannot enter literal key resolution or keychain restore.

* fix(vertex): refuse structured JSON carriers as literal keys

Reject object, array and quoted-string carriers directly so nested or escaped GCP credential material cannot bypass alias, ingestion or restore validation. Preserve non-JSON literal token handling and dedicated supported GCP-object ingestion.

* refactor(management): extract GCP credential route handling

Move credential-input rejection responses and locked provider deletion into a cohesive sibling module. Preserve validation responses, mutation ordering, save callback and post-commit cleanup behavior while keeping provider-routes.ts below the fixed 2000-line limit after dev integration.

 ## Storing keys in the OS keychain
 
+For Vertex, the dedicated API-key pool input (`POST /api/providers/keys`) accepts complete GCP
+`service_account` or `authorized_user` credential JSON after the provider has been created.
+The provider create/edit form and `ocx provider add --api-key` refuse credential JSON before
+saving: create the provider without a key, then add the JSON through its key pool. Paste the
+JSON contents, not a Windows, Unix, or relative file path. Multiple
+JSON objects separated by commas or whitespace are stored together as separate pool entries;
+the first becomes active. Configuration contains only `gcp-sa:<account>` references, never the
+credential JSON. Mixed JSON/literal-key bulk pastes are rejected as a whole; add literal keys
+separately. Storage failures leave the configuration unchanged and report a fixed error without
+echoing credential material. Empty marker accounts are invalid and do not fall back to host credentials.
+Paste one credential object or a sequence of objects, without an enclosing array or quoted string.
+Malformed credential text is rejected. If a selected stored credential is removed or becomes unreadable,
+Vertex refuses the request even when it previously cached an access token for that credential.
+Removing a key or provider, or replacing a provider with `ocx provider add --force`, deletes its unreferenced GCP credentials after the configuration is
+saved; a credential referenced by another provider is retained. If OS-store cleanup fails, a
+warning requests manual inspection without undoing the committed configuration removal.
+Ordinary keychain store/restore actions leave GCP markers and JSON in the OS store. Restoring
+credential JSON through a `keychain:` alias is refused, and cleanup preserves accounts still
+referenced through either marker spelling.
+Using a `keychain:` alias containing GCP JSON as an API key also refuses the request; select its
+`gcp-sa:` reference for Vertex authentication instead.
+Literal API keys must be plain token text: JSON objects, arrays and quoted JSON strings are refused
+in literal-key resolution and restore, including wrappers containing escaped credential text.
+Credential writes and marker persistence share the cleanup transaction lock, so concurrent
+removal cannot delete the stored JSON between read-back and the marker commit.
+
 By default a provider's `apiKey` and `apiKeyPool` sit in `config.json` (mode 0600, atomic writes).
 If you would rather keep the key material out of the file, move it into the OS credential store:

 ## Provider live operations and bounded editor input
 
+Offline removal in `src/cli/provider.ts` snapshots GCP marker references before deletion and runs
+the [post-commit credential cleanup](providers/google.md#vertex-credential-markers) only after saving;
+live and latest durable rows are captured under the same mutation lock as deletion persistence.
+
 `src/cli/provider.ts` selects explicit --live lifecycle operations before local configuration calls. `src/cli/provider-lifecycle-runtime.ts` pins the management target for roster/preset reads and one add/default/remove mutation, refuses redirects and never falls back to local state. Add is an upsert with an observed no-force check, not atomic create-only protection. Default is a standalone patch; live removal requires --yes and leaves dependency/default/account cleanup to the server. Local add keeps its default target and actually performs requested --sync before JSON output; configApplied and catalog convergence are separate, and an unchanged existing catalog can converge without new writes; saved-but-unavailable/refused/failed sync is nonzero, while policy skips retain truthful needsSync. Known catalog ownership and saved-config removal warnings reach human output and the local `sync.warning` receipt; only the owner's fixed path-free guidance and namespace count are projected, so appended arbitrary diagnostics remain private. Explicit local authentication/path overrides pass the management owner's completed-candidate validation before registration, saving, discovery or sync; unflagged local behavior is unchanged.
 
 `src/cli/provider-settings.ts` consumes only the three additional edit fields and owns pacing rules/status. Configured rules come from config, observations from the separate pacing endpoint. Scalar writes preserve observed model rules but replace the entire block without CAS; numeric changes do not implicitly enable pacing. Complete-file replacement is exclusive with scalar flags and uses the canonical pacing validator. `src/cli/provider-runtime.ts` propagates the safe provider edit result's numeric outcome and the connectivity test outcome. Failed connectivity remains exit 1 through the outer provider dispatcher; successful and non-applicable static-catalog observations remain exit 0.

 # Config Surface
-
+Pasted GCP JSON persists only as `gcp-sa:<account>` references in one pool transaction in `src/providers/api-keys.ts`; post-commit deletion follows [Vertex credential markers](providers/google.md#vertex-credential-markers).
 `src/config/schema/leaf-validators.ts` accepts only boolean `apiKeys[].allowMeteredComboTargets`; malformed entries are dropped rather than promoted. `src/types/config.ts` and combo validation define optional boolean target `metered`, normalized false when omitted, and optional per-combo `allowMeteredTargets` (default false, literal boolean validation shared by config schema and management API). Explicit consent is required under the [combo runtime contract](runtime.md#request-local-target-compatibility). Model-price overrides follow the [pricing contract](pricing.md). Quota activation reuses the existing next-reset fields without adding a polling configuration key. See the [quota activation contract](providers/openai-tiers.md#public-provider-contract). `src/types/config.ts` defines `anthropicAccountPool.routes` as ordered model rules. `src/oauth/anthropic-model-routes.ts` validates bounded names, full case-sensitive globs and stored account IDs; `src/config/diagnostics.ts` rejects malformed candidate writes. Load retains a malformed hand edit so unrelated providers survive, while the enabled Anthropic selector refuses it locally before dispatch. Saved rules remain inert when the pool is disabled; affinity is process-local. Request logs use only the rule’s 1-based `route:#<n>` position, never its configured name. `src/cli/hub-disable.ts` removes interdependent hub/loopback/role/hostname settings through `mutatePersistedConfig` and `validateConfigCandidate` in one commit. Top-level deletion intent uses `src/config/rebase-provenance.ts` and authoritative disk provenance in `src/config/live-reconcile.ts` to preserve removed hub bindings through later live saves, `src/config/live-topology.ts` keeps an independent active-topology baseline and merges desired next-start settings into a separate persistence projection, retaining actual socket identity and live hub/client topology during guarded saves and OAuth disk adoption. Client connections and runtimeRole remain one topology unit through connect/disconnect, including fresh disk-only connections. Disk additions/value updates and deletions all survive repeated saves without changing active topology. `src/config/api-key-reconcile.ts` merges key rows by stable ID under the existing save lock; either side's revocation defeats stale edits while disjoint names and rotations merge; unchanged live key membership/order adopts persisted ordering. `tests/config/hub-disable-live-save.test.ts` exercises disable followed by live key creation, rename, rotation, unrelated settings and repeated saves. Saved API keys have no immutable enrollment marker; explicit exact-ID revocation preserves all unselected keys.
 
 Native function-result injection follows [the separate opt-in control contract](transports/streaming-health.md#experimental-native-function-result-injection); this surface does not infer upstream support or alter its defaults.

+Provider PUT, POST and DELETE in `src/server/management/provider-routes.ts` run [GCP credential cleanup](providers/google.md#vertex-credential-markers) only after saving. `src/server/management/provider-gcp-credential-routes.ts` owns credential-input rejection responses and the locked deletion callback, which snapshots live and valid durable markers under the persistence lock. Rejected mutations and failed saves preserve secrets; other persisted references retain them. Route response shapes remain unchanged.
 `GET/PUT /api/codex-auth/preserve-signed-in` and CLI `account preserve-signed-in` expose the [signed-in quota policy](providers/openai-signed-in-preservation.md); strict boolean writes can explicitly release affected bindings/pins for the next request after persistence. The GUI retains its existing account controls. `src/server/management/combo-routes.ts` retains omitted `metered: true` metadata by trimmed provider/model identity during dashboard-shaped saves. Explicit false clears the flag; false defaults are omitted from persisted targets. Omitted combo `allowMeteredTargets` survives saves and renames; explicit false clears it and stays sparse. The CLI exposes `--allow-metered-targets on|off`, and receipts preserve the boolean. Key and loopback operator consent follow the [runtime contract](runtime.md#request-local-target-compatibility). Model-price APIs and receipt validation follow the [pricing contract](pricing.md). Anthropic OAuth account DTOs include `autoSwitchThresholdOverride` (integer or null),
 `autoSwitchThreshold` (pool default) and `effectiveAutoSwitchThreshold`. The dedicated
 `PUT /api/oauth/accounts/auto-switch` accepts `{ provider: "anthropic", accountId, threshold }`;

 Combo target `metered` metadata and configured-key opt-in follow the [runtime consent contract](runtime.md#request-local-target-compatibility). Subscription-to-Cursor-to-key regression coverage in `tests/adapters/anthropic/anthropic-subscription-chain.test.ts` checks unchanged healthy subscription wire bodies, effort, key authentication and cache controls, and structured runTurn 429 propagation. Configured spend ceilings bind adapter inference executors to the [seed and physical-start contract](transports/responses-spend.md#historical-pool-continuity-and-rollback). Zed completion and auth-recovery replays claim separately; token acquisition stays outside inference accounting. Claude CLI, CodeBuddy and Qoder each count one invocation toward the frozen request limit, seed before spawn and retain a producer through completion. Child-internal retries/tool turns are not separately counted; reported actual usage settles in full, including amounts above the seed estimate.
 Devin combines only [consecutive same-ID tool results](adapters/registry.md#devin-consecutive-tool-results), using linear accumulation while preserving intervening message slots, image parts and error markers without mutating the parsed request.
 Claude CLI replay, client tool capture and usage admission follow [Claude CLI replay](providers/claude-cli-replay.md). Anthropic account pause, model routes, quota labels, and the separate `anthropic2` pool (its helpers, quota, reset grants and management surfaces) follow the [Anthropic account-pool contract](providers/anthropic-account-pool.md). Devin Messages follows the [per-turn output ordering contract](clients/claude-desktop.md#devin-messages-output-ordering), preserving late signatures before text/tools without changing Responses or Chat ordering. The DeepSeek Harness account provider follows the [DSH account contract](providers/dsh-account.md).

 # Google Provider
 
+## Vertex credential markers
+
+`src/lib/gcp-adc.ts` resolves an explicit `gcp-sa:<account>` through the OS credential store.
+An empty or whitespace-only account is rejected before token resolution; it never selects host ADC.
+Marker payload readability is checked before returning a cached token; removing or locking the stored
+credential fails closed. Errors omit the marker account. Wrapped or malformed credential-shaped input
+is refused at ingestion and keychain restore, so it cannot become a literal config value.
+The leaf classifier in `src/lib/gcp-credential-input.ts` rejects structured JSON carriers (objects,
+arrays and quoted strings) and malformed GCP text reached through
+`keychain:` aliases before normal or quiet API-key resolution can return wire-header material.
+Post-commit cleanup skips empty or whitespace-only GCP marker accounts in both persisted references and captured removal candidates, so one malformed marker cannot block valid-account retention or cleanup. Request-time marker validation remains strict.
+`src/providers/api-keys.ts` stores pasted credential JSON as markers, including multiple JSON objects
+in one atomic pool update. Verified OS writes and marker persistence share the cleanup mutation
+lock. Rebased callbacks repeat idempotent writes before committing; failed batches remove only
+newly created, unreferenced secrets.
+The dedicated key-pool endpoint owns JSON ingestion. Provider POST/create/overwrite and CLI add
+reject raw JSON in active keys or submitted pool entries before saving; mixed JSON/literal-key
+bulk pastes are rejected before any store writes. OS-store failures return a fixed error without
+credential material. `src/server/management/provider-gcp-credential-routes.ts` and `src/cli/provider.ts` enforce
+this admission through `providerCredentialInputError` in `src/providers/api-keys.ts`; CLI registry input is checked before forward/OAuth branches can discard `--api-key`.
+The management helper also owns the locked provider-deletion callback, preserving fallback-default
+selection, custom-model/context-cap removal, persistence and subsequent marker cleanup order.
+`src/providers/gcp-credential-cleanup.ts` cleans removed markers after config persistence, including CLI `provider add --force` overwrites, under the
+  config mutation lock, retaining credentials still referenced by any persisted provider. CLI overwrite captures both live and latest durable rows under that lock. Management overwrite reuses `snapshotProviderGcpCredentialMarkers`; CLI and management deletion use `commitProviderGcpCredentialRemoval` to capture live and valid durable markers and persist removal without releasing the lock. Failed saves and refused CLI additions do not clean credentials.
+Reference retention compares OS account identities across both `gcp-sa:` and `keychain:`
+spellings. `src/providers/key-store.ts` leaves GCP markers stored during ordinary keychain
+store/restore and refuses to restore GCP JSON through a keychain alias; the shared classification
+in `src/providers/api-key-resolve.ts` reports those markers as OS-stored credentials.

Subject: [PATCH 47/72] fix(service): bind Linux health sentinel recovery to
 pidfd (#7133)

* fix(service): bind Linux sentinel recovery to a pidfd

* docs(service): correct the pidfd syscall-number comment

* test(service): count pidfs-backed pidfds on Linux 6.9+

* fix(service): settle a throwing pidfd kill as failed

* test(service): compare the pidfd leak check with a pre-spawn baseline

Bun can hold its own pidfd for a spawned child and close it when the child exits, so a count taken after spawning ends one lower. The final leak assertion now uses the count from before the fixture exists.

Subject: [PATCH 48/72] fix(codex): keep the desktop app open on codex-restart
 when its picker is current (#7149)

* fix(codex): keep the desktop app open when its picker is current on codex-restart

The desktop shell builds its model picker at launch, so it only needs a restart when it launched before the current catalog was written. Otherwise restart the app-servers alone; the desktop respawns its own child and keeps drafts, picker selections and pending approvals. Unreadable evidence falls back to the full restart.

Refs #4761

* fix(cli): report whether codex-restart kept the desktop app open

Refs #4761

* docs: describe the picker-aware codex-restart scope

Refs #4761

* fix(codex): judge the desktop picker against the bound catalog and report the reading

Address review on #7149: the catalog mtime only dates the catalog config.toml binds through model_catalog_json, so an unbound config is unknown and a binding changed by the request's own sync is stale. The response now carries desktopApp.pickerState so the CLI no longer claims a picker predated the catalog when the evidence was merely unreadable.

Refs #4761

* docs(codex): describe closed desktop restart outcomes

* docs(codex): name rebinding as a desktop restart trigger

* docs(cli): include rebinding in Codex restart help

+`ocx system codex-restart --yes` restarts Codex app-servers through the same module as
+`ocx sync --restart-codex`. It quits and relaunches the Codex desktop app when the app launched before the current model catalog was written or this request changed
+its `model_catalog_json` binding, because the model picker is built at
+launch. Otherwise the app stays open, respawns its own app-server, and keeps unsaved drafts and
+pending approvals. If the app or catalog state cannot be read, it takes the full restart. When
+the proxy itself is running inside the Codex app, the desktop restart refuses with an actionable
+message instead of promising a handoff it cannot complete.
+
+A `model_catalog_json` binding changed by this request also forces the desktop restart, even when the shell started after the catalog file was written.

Desktop-приложение Codex полностью закрывается и запускается заново, если оно было запущено до записи текущего каталога моделей или этот запрос изменил привязку `model_catalog_json`, потому что выбор модели строится при запуске. Иначе приложение остаётся открытым, само перезапускает свой app-server и сохраняет неотправленные черновики и ожидающие подтверждения. Если состояние приложения или каталога прочитать нельзя, выполняется полный перезапуск. Если сам proxy запущен внутри приложения Codex, перезапуск Desktop отказывается с actionable-сообщением вместо handoff, который он не может завершить.

+ *
+ * `ocx system codex-restart` used to quit and relaunch the desktop shell every time, which
+ * discards everything that lives only in the client: composer drafts, an unsent picker
+ * selection, a pending approval prompt. Upstream's own restart (`codex app-server daemon
+ * restart`) restarts only the app-server and lets clients reconnect, and the desktop app
+ * already respawns its own app-server child when it exits.
+ *
+ * The one thing an app-server restart cannot refresh is the picker: the renderer builds
+ * the roster once when the shell launches, and `model_catalog_json` is startup-only. So
+ * the shell has to restart only when it launched before the catalog it should show was
+ * written. The catalog writer skips byte-identical rewrites to keep this mtime honest
+ * (`src/codex/catalog/retained-sync.ts`), which is what makes the comparison usable.
+ *
+ * The mtime only means something for the catalog `config.toml` actually binds. With no
+ * `model_catalog_json` the shell shows Codex's own roster, which no local file dates, so
+ * an unbound config is `unknown`. `config.toml`'s own mtime is no substitute: injection
+ * rewrites it on every sync even when the bytes are identical. A binding changed by THIS
+ * request's sync is caught by the caller comparing it across the sync; one changed by an
+ * earlier sync over a byte-identical catalog file is not observable here.
+ *
+ * Anything we cannot read answers `unknown`, and the caller falls back to the full
+ * desktop restart: a stale picker the operator asked us to fix is the failure this
+ * command exists to prevent, so missing evidence never skips it.

 ## Explicit restart
 
-`ocx system codex-restart` requests a full Codex app and app-server restart through
-the management endpoint. `src/cli/capabilities.ts` and `src/cli/system-command.ts`
-warn that unsaved drafts, picker selections and pending approvals may be lost.
+`ocx system codex-restart` requests a Codex app-server restart through the management
+endpoint. `src/codex/app-server-restart-service.ts` also quits and relaunches the desktop
+app only when `src/codex/desktop-app/picker-freshness.ts` reports that a root shell started
+at or before the mtime of the catalog `config.toml` binds through `model_catalog_json`,
+because the picker is built at shell launch and an app-server restart cannot refresh it.
+A shell that started strictly later is left running (`desktopApp.reason: "picker_current"`),
+so its unsaved drafts, picker selections and pending approvals survive while it respawns its
+own app-server. An unbound config, an unreadable shell list, start time or catalog mtime, or a
+binding the request's own sync changed all take the full restart; `desktopApp.pickerState`
+reports which reading decided. `config.toml`'s own mtime is not evidence, because injection
+rewrites identical bytes. A binding changed by an earlier sync over a byte-identical catalog
+is not observable.
+`src/cli/capabilities.ts` and `src/cli/system-command.ts` warn that unsaved client state
+may be lost and report which outcome happened.
 The unconfirmed path sends no restart request; JSON output preserves refused outcomes.
+`tests/codex-integration/codex-app-server-restart-service.test.ts` and
+`tests/clients/desktop-app-restart.test.ts` cover the decision.
 
 Under the test preload's `OCX_TEST_HOME_GUARD=1`,
 `src/codex/desktop-app-restart.ts` skips real restart without an injected executor.

Subject: [PATCH 49/72] fix(providers): carry Zed, Qoder, and OpenCode Gemini
 compatibility (#7210, #7066, #7099, #7155) (#7216)

Carried from #7210, #7066, #7099, #7155 (one commit per source PR, original authors preserved). Closes #7097.

Remote exact-head validation (hosted GitHub Actions stalled; local tests not run by maintainer rule): union candidate codex/prr-integ-6 (368006f, tree 27fdc37) on mini (Windows) and lidge (Linux), typecheck + full suite, compared with base-dev 4ae49360b on each host.

   ([Global](https://qoder.com/account/integrations), [CN](https://qoder.cn/account/integrations)) and paste it as the provider's API key. The stored key reaches the CLI only as `QODER_PERSONAL_ACCESS_TOKEN` (Global) or `QODERCN_PERSONAL_ACCESS_TOKEN` (CN) in a scoped child environment.
 - **Region Isolation:** Each preset accepts only its canonical destination (`https://qoder.com` or `https://qoder.cn`) and resolves its own executable. Credentials, model cache, usage, and health are independent; neither region falls back to the other. An older custom provider named `qoder` with a different destination keeps its existing adapter and URL.
 - **Model Discovery:** `qoder --list-models` is the authoritative entitlement roster for the current PAT. The cache is bound to an irreversible fingerprint of the token, so switching accounts never reuses another account's roster. If discovery fails, the provider degrades to a stale cache and then the documented static seed.
+- **Token usage:** Qoder CLI reports zero token counts unless its usage switch is on, so each preset turns it on in its scoped CLI child environment: `QODER_EXPOSE_TOKEN_USAGE=true` for Global and `QODERCN_EXPOSE_TOKEN_USAGE=true` for CN, which reads only its own prefix.
 - **Tool Ownership:** The CLI runs single-turn `stream-json` with `--tools ""`, `--strict-mcp-config`, setting sources disabled, and session persistence disabled, so Codex keeps exclusive tool ownership. Client-declared tools are exposed through an isolated request-scoped MCP server.
 - **Image Input:** Qoder Global accepts image input through the Qoder CLI. OpenCodex forwards supported image inputs that reach the Global adapter to the CLI without maintaining a per-model vision capability allowlist there. Image compatibility and any model-specific preprocessing or routing are handled by Qoder. OpenCodex does not use the static discovery fallback roster to classify per-model vision capability. Qoder CN keeps its existing sidecar classification, and any residual raw-image request that reaches the CN adapter is rejected as `unsupported_input_modality`. OpenCodex serializes history before the current turn, but Qoder does not persist sessions, so prior images are replayed on later turns. In observed multi-turn image conversations, replayed images can become unreliably associated or effectively ordered relative to the historical text they originally accompanied.
 - **PAT recovery:** For both Qoder presets, a multi-key API-key pool can switch to another PAT on a supported authentication rejection or account-level quota exhaustion, but only before response content or an event that makes replay unsafe. Recovery requires Qoder-specific classification and respects credential-hop and send budgets; an HTTP 401/429 or quota message alone is not permission to replay. Single-key configurations do not rotate. Sharing the CLI runner does not enable this API-key recovery for CodeBuddy or self-authenticated Claude CLI.

Assistant reasoning replays as ChatMessagePrompt #11 thinking, #12 signature and #18 signature type (`src/adapters/devin/reasoning-signature.ts`): the #10/#21 pair arrives after the visible answer and becomes its own signature-only reasoning item, so a single unsigned thinking block plus exactly one signature-only block is replayed as one signed prompt, and a signature-only turn (GPT, Gemini) is replayed rather than dropped. An Anthropic signature is replayed, but because the streamed thinking is a summary the signature may not cover, a turn Cognition refuses with `invalid_argument` before any visible output (reasoning alone does not count) is retried once with Anthropic signatures withheld and the thinking text kept. `GetChatMessage` uses the Responses provider executor and shared physical-send budget; catalog, JWT, and `src/web-search/devin-executor.ts` native search support RPCs remain outside inference-send accounting. Provider-stated pre-output 429 reset delays are surfaced immediately by default, releasing shared active-turn capacity. A positive `OPENCODEX_DEVIN_STATED_RESET_WAIT_MS` explicitly enables bounded waiting and up to two replays on standalone turns, which hold that capacity until completion or cancellation. Combo children bypass that wait and surface a pre-output 429 so the next target can run. During an opted-in standalone wait, safe heartbeats commit the response preflight and keep the stream's stall watchdog fed. Invalid values fail closed to the immediate-refusal behavior. A recorded tenant host is used only for the stored account whose credential owns the transmitted key, searched in the configured provider id and then its deprecated alias; a configured, forwarded, or unmatched key uses the configured base URL or the US default. Native search previews the current route by effective adapter without mutating combo selection state, pins one admitted active-account snapshot for the request, and calls `GetWebSearchResults`, so it starts no CLI or second model. The wire model UID comes from the catalog's family metadata (`ClientModelConfig` #23/#30/#31): a family id with no effort anchors on the family's default member and selects the nearest enabled rung, rounding up first; an effort moves only the effort axis, to the lowest rung at or above it (else the highest below) while Fast Mode, 1M Context and the other axes stay at the anchor's values unless the caller asked for `fast` or a `1m` value; not lowering a requested effort outranks keeping those axes (an unranked member counts as lower), a disabled row the caller named is kept when the request still selects it so the preflight names that refusal, and resolution never leaves the family. Rows without family metadata fall back to suffix resolution, whose variant scan matches the collapsed base rather than a string prefix. With no caller or configured output cap, the selected row's catalog `maxOutputTokens` fills CompletionConfiguration #2; #3 is `max_newlines` and is sent at a fixed value, never a context window. The leading system text is sent as `GetChatMessage` #2, a failed tool result sets ChatMessagePrompt #9 and keeps an in-band `ERROR:` marker, and Gemini uids have JSON-Schema type arrays expressed as type-only `anyOf` branches in tool parameters. Shared constraints remain on the surrounding node, so nested schemas have one wire representation while outer enum/const, boolean constraints (including `not`, `oneOf`, and `allOf`) on null, and existing null-branch restrictions retain their conjunctive meaning. A null-only type keeps its null constraint even when an outer enum/const excludes null, preserving an unsatisfiable schema without producing an empty anyOf. Schema resource identifiers, anchors, definition maps, and existing anyOf branches remain on their original node. The type constraint is appended to existing allOf entries without shifting their indices, so JSON Pointer targets and reference scopes remain unchanged. A pre-output `invalid_argument` on a history whose word-piece estimate, using the sanitized and truncated tool descriptions actually sent on the wire, reaches 95% of the selected UID's catalog input window, capped by configured provider and model limits (512 KiB of text only when no window is known) is surfaced as `context_length_exceeded` so Codex compacts; a small request with the same code stays a plain 400. Known limit: a malformed schema on a history already at or above that 95% threshold is also reported as overflow because the upstream returns the same `invalid_argument`. The `COGNITION_BLOCKLIST_REWRITES` sanitizer rewrites exact phrases Cognition refuses with `permission_denied`; it runs only on instruction surfaces — tool descriptions and the #2 system prompt — while message text, replayed thinking (#11), and tool-call arguments stay byte-exact, because a rewrite there would silently change literal content such as patches or quoted file bytes; a trigger inside a data field surfaces as the upstream `permission_denied` instead (the Codex `<permissions instructions>` escalation boilerplate is the recorded #2 case). |

Subject: [PATCH 50/72] fix(catalog): carry Ultra Fast discovery, vision
 sidecar, model alias ids and auto-review override (#7115, #7126, #7173,
 #6867) (#7220)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Carried from #7115, #7126, #7173, #6867 (one commit per source PR, original authors preserved).

Remote exact-head validation (hosted GitHub Actions stalled; local tests not run by maintainer rule): union candidate codex/prr-integ-6 (368006f, tree 27fdc37) on mini (Windows) and lidge (Linux), typecheck + full suite, compared with base-dev 4ae49360b on each host.

 Image routing is capability-aware. Before an image-bearing upstream send, opencodex resolves the selected model's effective input modalities from runtime provider evidence, explicit operator declarations, backend/registry metadata, and generated vendor metadata. A target positively known to be text-only goes through the Vision Sidecar first; the image is described **before** the main call and replaced inline with text. A target positively known to support images receives the image directly. Unknown custom models keep the existing compatibility behavior rather than being guessed text-only.

+Vision-sidecar attachment metadata is projected after provider discovery/cache reads in `src/codex/catalog/routed-gather.ts`. The gather captures `visionSidecar.enabled !== false` before awaiting discovery, and `src/codex/catalog/gather-capture.ts` includes that effective flag in the flight key. Provider TTL/stale rows exclude synthetic sidecar image input; custom rows and synthesized combo members use the same captured switch. Explicit/native image modalities remain intact, and enabled advertisement retains the existing config-based consumer predicate without probing credential availability. An effective Vision switch change through `src/server/management/config-routes.ts` invokes the catalog-only management funnel after persistence to publish both catalog and cache; incomplete work is exposed as `catalogRefreshPending` without claiming client reload.

Live `/v1/models?client_version=...` discovery and both writers use current exact routed slugs; conflicting duplicates, templates, native/account rows and combos cannot grant capability.

 Separately, `src/codex/catalog/operator-tiers.ts` preserves a hand-supplied Ultra Fast tier from the exact persisted routed row only when `ultraFastTier` is enabled. Baselines and native templates cannot supply it. Current configured capability takes precedence; previously generated tiers cannot become operator evidence. Both overlays run after admission, preserve Fast policy and never create rows. Disabling `ultraFastTier` removes only independently supplied operator tiers; disabling the wire declaration removes generated ones. Operator defaults are retained only alongside an independently supplied tier declaration. Coverage: `tests/codex-integration/ultrafast-tier-honesty.test.ts`.
 Native rows are the one place the `ultraFastTier` flag itself adds a tier. `src/codex/catalog/native-ultrafast.ts` appends the documented `{ id: "ultrafast", name: "Ultrafast" }` descriptor to `service_tiers` and `"ultrafast"` to `additional_speed_tiers` on bare and trusted account-bound `gpt-6-astra` and `gpt-6.1-sol` rows, after the existing Fast tier and only when no Ultrafast entry is present. Codex reads the picker from `model_catalog_json` instead of ChatGPT's plan-aware live list, so without it Desktop never offers the choice. Each field it fills is recorded in the row's `opencodex_generated_service_tiers` marker, and disabling withdraws only marked fields (and only the unedited descriptor), so an operator-written native entry survives even when its text matches. Aliases, combos, reserve projections and other models are untouched, and the default tier never changes. Coverage: `tests/codex-integration/native-ultrafast-picker.test.ts`.

+ *

From: JUN <jun@lidgeai.com>
Date: Thu, 15 Oct 2026 20:43:49 -0700
Subject: [PATCH 51/72] fix(service): carry log rotation identities, Windows
 lock folder and remote-list RFC (#7186, #7203, #6157) (#7215)

Carried from #7186, #7203, #6157 (one commit per source PR, original authors preserved). #7154 and #7184 held out.

Remote exact-head validation (hosted GitHub Actions stalled; local tests not run by maintainer rule): union candidate codex/prr-integ-6 (368006f, tree 27fdc37) on mini (Windows) and lidge (Linux), typecheck + full suite, compared with base-dev 4ae49360b on each host.

+
+## Proposed decision
+
+Prefer a narrowly scoped, operator-opt-in policy in **native Codex app-server**
+for remote `thread/list` requests that do not supply a provider array. Keep the
+normal default-provider behavior, all existing authorization, and history intact.
+The mobile client's explicit all-provider request remains the simplest upstream
+client correction. Compare both with the previously tested local backend relay;
+do not turn that experimental relay into an installed feature in this PR.
+
+The current OpenCodex runtime and [ADR-5848](../../../structure/decisions/ADR-5848-provider-table-remote-history-visibility.md)
+remain unchanged. This proposal does **not** close #5848.
+
+## Work remaining
+
+- [x] Identify the native remote-connection boundary and existing provider predicate.
+- [x] Specify precedence and test the native-policy proposal offline.
+- [x] Retain and rerun the isolated loopback relay alternative.
+- [ ] Obtain upstream agreement on the native configuration/API contract.
+- [ ] Implement config/schema, trusted-origin plumbing, and Rust regressions upstream.
+- [ ] Verify native pagination, managed policy, account changes, and actual mobile resume.
+- [ ] Establish released-version/capability detection before adding any OpenCodex toggle.

+# Design comparison and proposed native contract
+
+This is an RFC, not an accepted architecture change or a released setting.
+`probes/native_policy.py` is an executable specification, **not native Rust code**.
+No probe is imported by OpenCodex or registered in its runtime/CLI/test suite.
+
+## Evidence and scope
+
+The source baseline is OpenAI Codex
+`1cc7e2361237ce7244430ee1d581c77f95c57ac8` and OpenCodex `dev`
+`eb7f0f0970c2298f8b2d66d170c4d4be869f301b`.
+
+- [Native list predicate](https://github.com/openai/codex/blob/1cc7e2361237ce7244430ee1d581c77f95c57ac8/codex-rs/app-server/src/request_processors/thread_processor.rs#L5456-L5530): explicit nonempty arrays filter to those ids; `[]` removes the provider predicate; omission defaults to the configured provider, except for related-thread queries.
+- [Remote connection origin](https://github.com/openai/codex/blob/1cc7e2361237ce7244430ee1d581c77f95c57ac8/codex-rs/app-server-transport/src/transport/remote_control/client_tracker.rs): native remote sessions open with `ConnectionOrigin::RemoteControl`; messages become native transport events.
+- [Original rationale, #5658](https://github.com/openai/codex/pull/5658): provider annotations/filtering address cross-provider resume/decryption failures. Visibility is not proof that a conversation is safe to resume under a different provider.
+- [OpenCodex mitigation, #6007](https://github.com/lidge-jun/opencodex/pull/6007): warnings and documentation without rewriting native history or intercepting native RPC.
+
+## Alternatives
+
+| Approach | Can leave official mobile app unchanged? | Additional ownership | Recommendation |
+| --- | --- | --- | --- |
+| Mobile explicitly sends `modelProviders: []` (or a chosen list) | No | Client's list behavior and resume UX | Simplest client correction; continue upstream tracking. |
+| Native, opt-in, remote-only default list policy | Yes, once a compatible native build ships | Native config and request policy, no extra service | **Preferred implementation proposal** when the host needs explicit control. |
+| Local relay selected through `chatgpt_base_url` | Potentially; live service not verified | Shared backend traffic, token forwarding, connection lifecycle | Research fallback, not a default or currently supported remedy. |
+| Globally change omitted filter to all providers | Yes | Changes behavior for every caller | Do not use: loses the existing default isolation behavior. |
+| Rewrite `openai` history tags to `opencodex` | Yes in some observations | Native SQLite/rollout state | Do not use: violates the retained history-writer boundary. |
+
+The native proposal minimizes new connection and credential handling; this is an
+engineering recommendation, not evidence of upstream acceptance or deployment.
+Neither upstream route can be delivered by modifying OpenCodex's `/v1` inference
+proxy alone. This PR publishes the comparison rather than disguising a probe as a fix.
+
+## Proposed native setting (name subject to upstream review)
+
+**Illustrative only; do not add this to current Codex/OpenCodex configuration.**
+
+```toml
+[remote_control]
+thread_list_model_providers = ["openai", "opencodex"]
+```
+
+Absent setting means opt-out. An explicitly empty array means all providers;
+a nonempty array means exactly those ids. Do not automatically infer equivalence
+from provider names, model names, or a shared URL. The setting changes listing,
+not authentication, permission checks, routing, compaction, or resume semantics.
+An operator who only needs two provider ids need not opt into every provider.
+
+### Precedence
+
+1. Existing authentication and managed remote-control policy still run first.
+2. A request's explicit provider **array**, including `[]`, always wins.
+3. With no array, parent/ancestor queries retain their current no-default-filter behavior.
+4. Only a server-identified remote connection may use the operator's configured policy.
+5. With no policy, and for every non-remote connection, preserve the existing default.
+
+Typed Rust `Option<Vec<String>>` treats omission and JSON `null` alike. This
+proposal deliberately applies its default to both. The raw relay probe preserves
+all present JSON keys, including null; that difference is documented and must not
+be mistaken for identical behavior between the two alternatives.
+
+Use the native `ConnectionOrigin` attached to the connection. Never infer remote
+origin from clientInfo.name, a user-agent, JSON fields, or a caller-supplied header.
+The Python enum tests only model this trusted input; they do not prove authentication.
+
+### Native implementation boundary
+
+The upstream change must add and validate the config contract, snapshot it with
+the native app-server's effective configuration, carry the trusted connection
+origin to the `thread/list` handler, and resolve the provider predicate before
+calling the existing store pagination. A new RPC layer is unnecessary.
+
+Conceptual selection, **not a drop-in patch**:
+
+```text
+if request supplies provider array: use that array
+else if parent/ancestor query: use existing related-thread behavior
+else if trusted origin is RemoteControl and operator policy is configured:
+    use the configured array
+else: use existing configured-default behavior
+```
+
+Do not add a global exception to `list_threads_common` for all callers. Do not
+change `thread/start`, `thread/resume`, `turn/start`, stored provider metadata,
+or request error handling. Keep source/cwd/archive/project filters and ordering.
+The new configuration's trust/precedence should prevent project content from
+silently opting an operator into a broader default; upstream must choose and test
+the appropriate configuration layers and any managed restrictions.
+
+Hold one effective policy throughout a listing/pagination sequence. A changed
+policy requires a fresh listing cursor; do not combine pages obtained under
+incompatible filters. Native tests must pin behavior with actual cursor semantics.
+The fixture tests here use integer pagination, not native opaque cursors.
+
+## Local relay alternative: what was and was not shown
+
+[Native startup](https://github.com/openai/codex/blob/1cc7e2361237ce7244430ee1d581c77f95c57ac8/codex-rs/app-server/src/lib.rs)
+uses `config.chatgpt_base_url` for remote control. The
+[URL protocol](https://github.com/openai/codex/blob/1cc7e2361237ce7244430ee1d581c77f95c57ac8/codex-rs/app-server-transport/src/transport/remote_control/protocol.rs)
+accepts loopback URLs. A host-side relay is therefore a concrete design alternative:
+
+```text
+unchanged mobile <-> existing ChatGPT backend <-> local relay <-> native app-server
+```
+
+Connection establishment starts on the host. Enroll/pair/refresh can be forwarded
+rather than reimplemented. However, `chatgpt_base_url` is shared with
+[authentication configuration](https://github.com/openai/codex/blob/1cc7e2361237ce7244430ee1d581c77f95c57ac8/codex-rs/core/src/config/auth_keyring.rs)
+and other backend consumers. A WebSocket-only implementation is insufficient.
+[Enrollment persistence](https://github.com/openai/codex/blob/1cc7e2361237ce7244430ee1d581c77f95c57ac8/codex-rs/app-server-transport/src/transport/remote_control/enroll.rs)
+also keys state by URL/account/client, so changing the URL can affect enrollment
+selection; whether live re-pairing is required remains unverified.
+
+The retained relay fixture accepts only literal `127.0.0.1` HTTP upstreams and
+synthetic credentials. It is not a production service and cannot be configured
+for ChatGPT. It handles regular and single-chunk frames; multi-chunk messages are
+passed unchanged. Actual protocol-v3 segmentation, native reconnect/ACK/cursors,
+account changes, managed network policy, and full backend compatibility remain
+release gates, not claims supported by these tests. See native
+[WebSocket handling](https://github.com/openai/codex/blob/1cc7e2361237ce7244430ee1d581c77f95c57ac8/codex-rs/app-server-transport/src/transport/remote_control/websocket.rs).
+
+No global base-URL mutation, token-pool integration, production listener,
+configuration migration, history write, or authentication bypass is proposed here.
+
+## Upstream and downstream follow-through
+
+An upstream implementation needs Rust config/schema, origin-scoping, explicit/null/
+related-query, pagination, and managed-policy tests. Keep existing defaults intact.
+Document the omitted/default behavior and regenerate affected schema/TS fixtures.
+
+After an accepted implementation is released, OpenCodex may consider an opt-in
+integration with positive capability/version evidence and precise configuration
+ownership/restoration. Merely writing an unknown TOML key is not a feature test.
+Until then, retain #6007's warnings and keep #5848 open. Do not suppress the warning
+because an experimental setting was written or a fixture passed.

+# Verification
+
+Status: local evidence for an RFC. The probes are executable specifications that
+run on demand; no CI workflow runs them, and nothing in the OpenCodex build, test,
+or runtime path imports them. All inputs, accounts, tokens, thread ids, and
+database rows are synthetic. No native Codex process, user home, installed
+config, or real service is accessed.
+
+## How to run
+
+From the repository root:
+
+```sh
+cd devlog/_plan/260928_remote_thread_provider_policy/probes
+python3 -m unittest -v test_native_policy test_probe
+```
+
+The socket suite needs aiohttp. Install it into a scratch directory, not the
+repository or a system site-packages:
+
+```sh
+python3 -m pip install --target "$SCRATCH_DIR" aiohttp
+PYTHONPATH="$SCRATCH_DIR" python3 -m unittest -v test_native_policy test_probe test_loopback_bridge
+```
+
+## Inventory
+
+63 tests across three suites:
+
+- 23 tests (`test_native_policy`) specify the proposed native policy: opt-out,
+  trusted-origin scoping, explicit arrays, null semantics, parent/ancestor
+  exceptions, immutable policy, exact ids, UUID thread-id validation, and
+  synthetic paginated fixture reads.
+- 29 raw-frame tests (`test_probe`) cover the relay alternative's
+  ordinary/single-chunk rewrites, byte-identical pass-through, limits, and
+  unsupported inputs.
+- 11 localhost HTTP/WebSocket tests (`test_loopback_bridge`) use a mock host and
+  mock backend, checking two-way traffic, fixture auth/headers, explicit filters,
+  enrollment, unrelated HTTP, fixture endpoint restrictions, and both directions
+  of close-code forwarding.
+
+The first 52 use the Python standard library only.
+
+The synthetic database has 5,200 `openai` rows, one `opencodex` row, and one
+`other` row. Default filtering yields one; the two-id opt-in yields 5,201; all
+providers yields 5,202. Page sizes 1, 37, and 1,000 are exercised. The fixture
+dump hash stays unchanged after reads. This demonstrates the specification, not
+native SQLite schema compatibility or actual mobile results.
+
+## Recorded runs
+
+| Date | Environment | Suites | Result |
+| --- | --- | --- | --- |
+| 2026-09-28 | author, local | native policy + raw frame | 52 passed |
+| 2026-10-13 | Linux, Python 3.12.14, aiohttp 3.14.4 | all three | 63 passed |
+| 2026-10-15 | macOS, Python 3.9.6, aiohttp 3.13.5 | all three | 63 passed |
+
+Each run reflects the probe source at that time; a later edit to a probe needs a
+fresh local run.
+
+## Not executed / not established
+
+- Native Rust implementation, compilation, config/schema generation, or native tests.
+- Actual ChatGPT mobile pairing, full pagination, resume, token renewal, or reconnect.
+- Production multi-segment relay support or management/security review of a relay.

 # Test Sandbox Cleanup
 
+## Windows runtime namespace
+
+`src/codex/user-identity.ts` keys runtime namespaces on the effective SID and environment-independent
+LocalAppData. `src/codex/windows-local-appdata.ts` calls `SHGetKnownFolderPath` in-process on Windows
+x64, loading Shell32/Ole32 from the OS-resolved system directory. It uses `KF_FLAG_DEFAULT_PATH`
+and a null token, bounds UTF-16 decoding, and frees the allocation even when the API fails.
+Unsupported FFI retains the bounded trusted PowerShell helper; native API failures refuse.
+`USERPROFILE` and `LOCALAPPDATA` never choose this root. Runtime canonicalization/reparse checks
+and the Bun test lock's required ACL hardening remain separate admission checks.
+
+## Sandbox lifecycle
+
 The batch runner's per-process home isolation and live-home/service-manager guards remain active
 because the preload installs them before the lock boundary. `tests/preload.ts` resolves cleanup
 dependencies after home/lock admission and before test cases. Teardown awaits native-main startup

Date: Thu, 15 Oct 2026 20:44:08 -0700
Subject: [PATCH 52/72] fix(responses): carry incomplete reasons, terminal
 refusals, offline continuation tests and MiMo envelope repair (#7122, #7152,
 #7068, #7214) (#7218)

Carried from #7122, #7152, #7068, #7214 (one commit per source PR, original authors preserved). #7095 held out.

Remote exact-head validation (hosted GitHub Actions stalled; local tests not run by maintainer rule): union candidate codex/prr-integ-6 (368006f, tree 27fdc37) on mini (Windows) and lidge (Linux), typecheck + full suite, compared with base-dev 4ae49360b on each host.

 | `src/oauth/` | OAuth providers, token storage, refresh, and auth-token resolution. Meta Muse device authorization, polling, and key-mint JSON responses share the 64 KiB bounded-body ceiling and the request's deadline; oversized declared or streamed bodies are rejected before JSON parsing. The login callback listener binds a per-provider FIXED loopback port, so consecutive logins reuse the same number; every response it sends ends its connection (`Connection: close`, including non-callback paths such as a stray `/favicon.ico` 404). Stopping the listener does not close an established socket, so without that a pooled client would deliver the next login's callback to the retired flow, which rejects the unknown state as a CSRF mismatch while the live flow waits. Command Code manual callback JSON remains opaque to the shared `code#state` parser and is state-validated by its provider parser. A raw Command Code paste with an explicit `#state` suffix must match the flow state on the direct prompt as well. Kiro add-account identity prefers same-session `whoami` over a leftover SQLite state profile, and never persists the Builder ID service profile ARN as `accountId`. Because an organization profile ARN is shared by its users, `src/oauth/kiro-account-identity.ts` keys Kiro rows by ARN plus the same-session `whoami` email (#6641): a login without a user keeps the legacy ARN identity but never replaces an identified user of the same profile unless the refresh token proves the same CLI session; reauth of a row with a user and rotated-CLI recovery require that same user (a row without a user recovers only while no other row shares its profile, and explicit reauth may record its user unless that user owns another row of the profile), an unmatched login claims an identity-less active slot only as the same session while the profile has other rows, and Add account records the current CLI user on ARN-only rows through a fenced same-session bind. ChatGPT token exchange and refresh in `src/oauth/chatgpt.ts` compose caller cancellation with a fresh 30-second per-fetch deadline covering headers and body. Error bodies are capped at 16 KiB bytes and success JSON at 64 KiB; each settled call detaches its caller listener and clears its timer. The registration in `src/oauth/index.ts` preserves that signal and uses the shared Codex classifier through `ChatGptTokenError`: terminal grant refusals require an explicit allowlisted terminal OAuth code and mark only the matching generation `needsReauth`; free-text descriptions never establish terminality; transient failures remain retryable. HTTP-derived errors expose only status and allowlisted code. Cancellation and deadline errors use fixed AbortError/TimeoutError messages; transport and parsing failures also use fixed messages, without raw reasons or causes, and never mark reauthentication. The registry preserves its own stale-flight error. `tests/oauth/chatgpt-token-expiry.test.ts`, `tests/oauth/chatgpt-token-boundaries.test.ts` and `tests/oauth/oauth-refresh-generic-lock.test.ts` cover these boundaries with synthetic responses. |

An upstream that mints an id from the call's position in its response repeats `call-0-0` on every turn; a Messages client has already paired that id, drops the duplicate, and is left with a call that has no result, so the turn reads as empty and the model re-issues it indefinitely. Only a **repeat** is rewritten — the first occurrence stays byte-identical, leaving prompt-cache keys, reasoning-replay lookups and already-unique upstreams untouched. The ids to avoid come from the caller's history, captured in `buildRequest` (the only point that sees it) and applied at emission, never at ingestion: ingestion matches streamed deltas against the id upstream sent, so rewriting there would strip a pending call of its identity mid-stream. A repeat takes a `-<n>` suffix, never `_<n>`, because `<earlier>_<digits>` reads as a batch sub-call of `<earlier>`; occupied-set search resumes by suffix width and retained base prefix, including when siblings converge as `-9` becomes `-10`. Covered by `tests/adapters/openai/openai-chat-tool-call-id-remint.test.ts`. |

It copies only changed `incomplete_details.reason` metadata, leaving output content and all other response fields intact.

The web-search and image sidecar loops (`src/web-search/loop.ts`, `src/images/loop.ts`) check `isTerminalRefusalIncomplete` before looping, on every inbound wire: a refused iteration that carried a sidecar call ends the turn instead of running the call and re-asking the model with the refused context (`tests/web-search/web-search-terminal-refusal.test.ts`, `tests/images/loop-terminal-refusal.test.ts`); `src/web-search/run-turn-loop.ts` already stops on any incomplete.

+Responses WebSocket terminal frames normalize known `incomplete_details.reason` aliases under the [incomplete reason contract](responses-wire-shapes.md#adapter-incomplete-reasons), including native control chains.

 ## Heartbeat and stall deadline
 
 RunTurn search interception forwards adapter heartbeats immediately and emits progress for buffered semantic events. Its bridge uses the search plan's stall deadline so a bounded sidecar search fits the watchdog budget.

Subject: [PATCH 53/72] feat(advisor): carry bounded retention and adaptive
 consultation (#7134, #7124) (#7219)

Carried from #7134, #7124 (one commit per source PR, original authors preserved).

Remote exact-head validation (hosted GitHub Actions stalled; local tests not run by maintainer rule): union candidate codex/prr-integ-6 (368006f, tree 27fdc37) on mini (Windows) and lidge (Linux), typecheck + full suite, compared with base-dev 4ae49360b on each host.

+`adaptive` ajoute à la consultation initiale une consultation lorsque la même vérification, dans le même répertoire, échoue, qu’une modification de fichier ultérieure réussit, puis qu’une nouvelle exécution échoue encore. Une réussite efface l’échec ; une vérification démarrée avant la modification ne compte pas comme une nouvelle tentative après réparation. Les étapes initiale et réparation ont des revendications distinctes. Une identité de conversation stable est requise pour l’automatisation. Les appels/résultats doivent être appariés avec un code de sortie explicite. Scripts complexes, lots, modifications shell et sorties ambiguës ne déclenchent rien.
+
+Configurez `ocx advisor set --policy adaptive --max-consultations 2`. Les tentatives manuelles et automatiques partagent un budget de 1 à 3 par tâche, réservé avant envoi dans `OPENCODEX_HOME/advisor-budget.sqlite`. Un redémarrage ou un changement de worker ne le remet pas à zéro. Seuls les condensats, compteurs et expirations sont conservés, pendant 24 heures après la première tentative (512 tâches au maximum). Si le budget est inaccessible ou épuisé, le worker continue. Les appels envoyés puis échoués ou annulés restent réservés car ils peuvent coûter. Sans identité stable, seuls les appels manuels limités par requête restent disponibles.
+
+La page Advisor et `ocx advisor activity --json` (`GET /api/advisor/activity`) montrent jusqu’à 100 entrées de métadonnées du processus sur 24 heures ; la page visible s’actualise toutes les cinq secondes. Elles incluent motif, état, modèles, durée, tokens d’entrée/sortie signalés et efforts demandé et traduit par l’adaptateur. Aucun texte, commande, conseil ou identifiant de conversation n’est conservé ; un redémarrage efface ces entrées. La traduction décrit les paramètres envoyés et ne garantit pas le raisonnement interne. Les données absentes restent inconnues ; adoption et coût exact ne sont pas déduits.

+
+`adaptive`는 초기 상담 외에 같은 작업 디렉터리의 같은 검증이 실패하고, 이후 파일 편집이 성공한 뒤 새 검증 실행도 실패했을 때 상담합니다. 검증 성공은 실패 상태를 지웁니다. 편집 전에 시작한 검증은 수정 후 재시도가 아닙니다. 초기 상담과 수정 실패 상담은 별도로 중복을 방지하며 자동 상담에는 안정적인 대화 식별자가 필요합니다. 짝지어진 도구 호출/결과와 명시적 종료 코드가 필요합니다. 복잡한 스크립트, 일괄 호출, shell 편집 및 모호한 출력은 트리거하지 않습니다.
+
+`ocx advisor set --policy adaptive --max-consultations 2`로 설정합니다. 수동 및 자동 시도는 작업별 1–3회 예산을 공유하며 전송 전에 `OPENCODEX_HOME/advisor-budget.sqlite`에 예약합니다. 프록시 재시작이나 Worker 변경으로 초기화되지 않습니다. 작업 다이제스트, 횟수, 만료 시간만 보관하며 첫 시도 후 24시간에 만료됩니다(최대 512개 작업). 예산을 사용할 수 없어도 Worker는 계속합니다. 전송된 실패·취소 호출도 비용이 발생할 수 있으므로 예약을 돌려주지 않습니다. 안정적인 식별자가 없으면 요청별 수동 상담만 가능합니다.
+
+Advisor 페이지와 `ocx advisor activity --json`(`GET /api/advisor/activity`)은 이 프로세스의 최근 24시간 상담 메타데이터를 최대 100개 표시합니다. 화면이 보일 때 5초마다 갱신합니다. 이유, 상태, 모델, 시간, 보고된 입력/출력 토큰, 요청 및 어댑터 매핑 추론값을 포함합니다. 작업 본문, 명령, 조언, 대화 식별자는 저장하지 않으며 재시작 시 사라집니다. 매핑은 전송 파라미터의 증거일 뿐 내부 추론을 보장하지 않습니다. 미보고 값은 알 수 없음으로 유지하며 정확한 비용이나 조언 채택을 추정하지 않습니다.

+
+The adaptive task budget counts manual and automatic **attempts**, across requests and worker
+model changes. The server reserves an attempt before dispatch in a private
+`advisor-budget.sqlite` file in `OPENCODEX_HOME`; proxy restarts do not reset it. A task is
+identified by a digest of conversation identity and the latest user-task boundary. Reservations
+expire 24 hours after the first attempt, so this is a bounded task-lifetime approximation,
+not a permanent session or daily monetary budget. Only digests, counts and expiry times are
+stored. There is room for 512 live tasks; a full, unavailable or locked budget skips the expert
+call while the worker continues. Failed or disconnected dispatched calls retain their reservation
+because they may have incurred usage. Revoked consent before dispatch spends no allowance.
+Clients without a stable identity keep manual, request-bounded access but receive no automatic
+adaptive consultation. Legacy `manual` and `preflight` retain their previous task-dedup behavior.
+
+The collector recognizes paired shell calls with explicit numeric exit status, including
+`exec_command`, `shell_command`, `shell`, `Bash`, and terminal `write_stdin` polls. Supported
+commands include common Bun/npm/pnpm/yarn test, typecheck, lint, check and build commands,
+`pytest`, `python -m pytest`, `tsc`, `eslint`, `cargo test/check/clippy/build` and `go test/vet`.
+File edits use successful `apply_patch`, `Write`, `Edit`, `write_file` or `edit_file` results.
+Single Code Mode helpers with literal JSON arguments (bare keys accepted) are recognized;
+arbitrary JavaScript, batches, shell pipelines/substitutions, shell-based edits, ambiguous
+output and error prose alone provide no trigger. At most the latest 512 messages since the

 - `on` does not grant consent. Without current consent it refuses and prints the disclosure. `on --ack-context-sharing` records consent v1 and enables. `consent --revoke` removes consent and stops task-context transfer.
 - The advisor model may be any routable model string: a bare native model, an explicit `provider/model`, or an account-qualified native model.
 - `policy: preflight` makes OpenCodex attempt one automatic consultation per task with a stable conversation identity once the task shows orientation evidence (an assistant tool call or a tool result after the latest user message). Without a stable identity, each eligible request may trigger another consultation. `policy: manual` consults only when the worker calls the synthetic `advisor` tool. Neither path sends task context without current context-sharing consent.
+- `policy: adaptive` adds evidence-based failed-repair consultation after the same validation fails, a file edit completes, and validation fails again. Automatic calls require a stable conversation identity. `set --max-consultations <1-3>` caps adaptive task attempts, including manual calls, in a durable 24-hour budget. No semantic stuck detection is claimed.
+- `activity` reads up to 100 recent consultation metadata records (trigger, status, models, requested and mapped effort, duration, reported tokens); no task or advice content is retained. Records are process-local and expire after 24 hours. Missing mapped effort means unreported, not successful application.
 
 ### `ocx agent status`

+  request cap and four-continuation cap remain hard bounds.
+
 ## Observability
 
 Every consultation writes one structured `[advisor]` log line (trigger, worker model, advisor
 model, duration, status, usage) and the loopback call lands in usage accounting as its own
 request under the advisor model. Consultation usage is never merged into the worker's terminal
 usage; intercepted worker legs are, via the same usage-merge rule the terminal guard applies.
+
+`src/advisor/activity.ts` holds config-scoped process memory: at most 100 records, at most 24
+hours old, with pruning on access and no timer. `GET /api/advisor/activity` and `ocx advisor
+activity` expose trigger, status, models, requested/mapped effort, duration and reported tokens.
+There are no task bodies, commands, advice, conversation identifiers or provider error bodies
+in these records. Dashboard polling runs only while its page is visible. Restart clears activity,
+independently of the durable budget; no adoption score or exact monetary cost is inferred.
+
+`src/server/inference/advisor-diagnostics.ts` carries bounded serialization evidence in the
+loopback response only for the process-capability-authenticated Advisor caller. Translated
+paths use adapter-owned `effectiveEffort`; native Chat observes the finalized request body.
+No requested value is substituted for missing wire evidence. The activity UI displays unknown
+when unreported and does not claim verification of a provider's internal reasoning.

Carried from #6718.

Remote exact-head validation (hosted GitHub Actions stalled; local tests not run by maintainer rule): union candidate codex/prr-integ-6 (368006f, tree 27fdc37) on mini (Windows) and lidge (Linux), typecheck + full suite, compared with base-dev 4ae49360b on each host.

 Antigravity catalog rows carry the observed complete effort map from `src/providers/antigravity-models.ts` through the in-memory cache. `src/providers/antigravity-effort-families.ts` uses that evidence to group public rows and project suffix allowlists into the base selection, including both final catalog merge callers. Internal retained suffix rows remain available to combo resolution. Authoritative new-model reconciliation normalizes both the prior baseline and policy input before detecting arrivals: an existing suffix family is not a new model. All-disabled tiers transfer a base disable once; a known base keeps the operator's later choice. Genuinely new families still follow new-model policy. Saved defaults, combo targets, suffix disables and provider selections remain unchanged. A discovered ladder advertises only its wire-backed efforts unless explicitly overridden; unknown single-wire models gain no invented ladder.
 
 Known Claude Sonnet and Opus 5.5 base and low/medium/high IDs share a deterministic usage identity in `src/providers/antigravity-models.ts`, independently of live discovery. This accounting map does not migrate saved routing selections; Claude 4.6 and unknown suffix identities remain unchanged. Antigravity model entitlement is per account: one account may list Claude 4.6, another only the Claude 5.5 suffix families, and Gemini 4 Argon only on Ultra/Enterprise. `ANTIGRAVITY_MODELS` is therefore a static superset (Gemini 3.8 Flash, Gemini 4 Argon, Claude Opus 5.5, Claude Sonnet 5.5), and `ANTIGRAVITY_KNOWN_PICKER_MODELS` keeps dropped bases known to routing, discovery collapse and usage identity. The catalog exposes only what the active account's authoritative discovery returns. `src/providers/antigravity-account-roster.ts` records each account's discovered roster (in memory, six-hour freshness, scoped to config home); `src/oauth/generic-account-failover.ts` ranks Antigravity accounts by it the way it ranks Kiro listings: a listing account wins, a known non-listing account is skipped while another remains, and an account without a fresh roster is unknown and stays usable. Gemini 4 Argon requests and Antigravity model discovery send the Antigravity CLI User-Agent; every other model keeps the IDE User-Agent.
-
+When the `retrieveUserQuotaSummary` endpoint has no usable result, `src/providers/quota/antigravity.ts` preserves bounded per-model `quotaInfo` measurements from `fetchAvailableModels` alongside the existing first-seen Gem/Cla family summaries. Model windows carry the exact CCA wire ID and distinct labels of at most 128 characters for display and diagnostics; GUI summaries and native compact rows preserve the discriminator, retain details, and exclude model readings from headline and severity selection; account and provider routing ignore these rows and continue to use family summaries, and `src/quota/window-mapping.ts` keeps them out of quota-reset observation so one pool reset notifies once. A missing model row or failed probe is unknown evidence, not a model eligibility verdict. Per-account cache entries are bound to the current credential and project identity. Paused reads retain only current last-good measurements without probing; `src/providers/quota/account-row.ts` preserves private currentness callbacks through account-row projection until management publication.

Subject: [PATCH 55/72] feat(providers): carry opt-in API key round-robin and
 per-key pacing (#6937) (#7135)

Carried from #6937.

Remote exact-head validation (hosted GitHub Actions stalled; local tests not run by maintainer rule): union candidate codex/prr-integ-6 (368006f, tree 27fdc37) on mini (Windows) and lidge (Linux), typecheck + full suite, compared with base-dev 4ae49360b on each host.

 it unless `enabled: false`.
 
+When round-robin key selection is enabled, queued requests recheck key cooldowns before sending and acquire pacing capacity for any replacement key. This applies to native Chat, Messages, Responses and compact. Waiting for replacement-key capacity does not consume the upstream response-header timeout. Per-key pacing and round-robin use guarded HTTP/SSE even when upstream WebSockets are enabled; WebSocket-only steering and injection require a route without those key policies. This does not change the saved active key. An established upstream turn keeps its credential; later sends are refused if that key cools. Pre-output key rejection can recover to a healthy key within the existing request limit. Direct Images and compact requests record genuine 401/429 cooldowns without replaying that paid POST.

 ### Anthropic API-key credit exhaustion
 
 Anthropic API-key pools with at least two keys automatically try a sibling key when a complete HTTP `400` or `402` error states that the credit balance is too low to access the Anthropic API. This applies to `invalid_request_error`, `billing_error`, and `permission_error` before any text or tool output. Key rotation and pool strategies skip the failed key for one hour, because an empty balance only clears when credits are added; when every key is out of credit, requests still use the active key and return Anthropic's original error; choosing the key as active in the dashboard, or restarting the proxy, clears that hold after a top-up. Replacement sends share the request's send limit. Ordinary `400` errors stay terminal, and this does not enable same-key retries or change OAuth account routing. A header override that sends a different credential cannot cool or rotate the selected pool key.

An explicit pin requires an HTTPS target and fails locally when it cannot be honored. Set `http1.1` when a provider's HTTP/2 SSE stream stalls instead of delivering events — the symptom is a long-running streaming request that produces nothing and eventually times out.

Google can still detect, rate-limit, suspend, or ban the account you signed in with, and you alone carry that risk. It is off by default and accepted only with the Google adapter, Cloud Code Assist mode, and Google's canonical HTTPS Antigravity hosts. Redirects stay manual. The provider's own `proxy`/`noProxy` route is carried by the TLS transport; a route it cannot keep fails the request instead of leaving by another path, which includes any direct route while `HTTP_PROXY`, `HTTPS_PROXY`, or `ALL_PROXY` is set. `GET /api/providers` reports the profile state as `pending`, `active`, or `failed`.

 The concurrency slot stays occupied until the upstream request finishes, including the final streamed response bytes. Requests above the applicable provider and model limits wait in the pacing queue; when a slot is released, the next eligible request is admitted. Queue waiting does not consume the upstream response-header timeout.
 
+For multiple API-key pool entries, opt into normal-request distribution separately from the existing failure-selection `apiKeyPoolStrategy`:

+```json
+{
+  "requestPacing": {
+    "enabled": true,
+    "keySelection": "round-robin",
+    "maxConcurrentRequests": 10,
+    "keys": { "requestsPerMinute": 15, "maxConcurrentRequests": 1 }
+  }
+}
+```
+
+This admits at most ten active requests across the provider and one per credential reference, with starts on each reference at least four seconds apart. These are local upper bounds, not a promise of upstream capacity. A provider-wide RPM setting, when present, remains an aggregate limit and does not multiply with key count. Key limits span models; model rules remain additional restrictions. Projects sharing quota need an appropriate aggregate limit; TPM and daily quotas are not tracked here.
+
+Round-robin selects keys per request without saving a new active key. Known 401/429 cooldowns are skipped; when none remains eligible, new requests receive a retryable 429 instead of repeatedly sending. Already queued work normally retains its selected key and may wait behind that key even when another is idle. If that selection becomes cooled or invalid, the request selects an eligible key again and reacquires pacing admission for it; the bounded queue expires rather than waiting forever. Selection and diagnostics are process-local, reset on restart, and do not equal balanced token usage or billing. Starts count pacing admissions, including work cancelled before dispatch. OAuth and forwarded credentials keep their existing selection. The dashboard shows key handles, starts, in-flight work, queued work and known cooldowns, never secret key values. These limits cover the inference pacing executor, not the standalone Images relay's direct fetch.

Turn-scoped adapters follow the same rule before invocation.

Native Messages revisits mixed distributed 401/429 outcomes with its existing counters. Native Chat and Messages require the physical outgoing credential to match the selected distributed key before pooling a rejection; Messages honors the configured `x-api-key` or Bearer transport while rejecting a conflicting credential header; configured credential overrides cannot cool unused entries.

Native Responses captures distributed-key ownership after connection-policy rewrites in `src/providers/api-key-response-ownership.ts`; terminal 401/429 responses settle cooldown only after same-key retry policy, and a failed replay admission or synthetic replay refusal retains the last genuine refusal. Failure ownership accepts an already cooling, still-configured credential so concurrent late 401s extend earlier short cooldowns; physical-send eligibility still refuses cooling credentials. Reused responses, credential/destination overrides, stale revisions and synthetic refusals cannot confer ownership. Local pacing errors retain 429 and Retry-After at the passthrough catch boundary.

Subject: [PATCH 56/72] refactor(proxy): share opaque transport with desktop
 relay (#7120)

Contributed by @lcxhh521.

Remote exact-head validation (hosted GitHub Actions stalled; local tests not run by maintainer rule): union candidate codex/prr-integ-6 (368006f, tree 27fdc37) on mini (Windows) and lidge (Linux), typecheck + full suite, compared with base-dev 4ae49360b on each host.

 Choosing an account-qualified model does not enable credit spending. Stored accounts obey **Use credits after limit** during authentication, when credentials are prepared, and before Responses HTTP or WebSocket dispatch after pacing or retry waits. A held request reports the credit policy, not an authentication failure; wait for the reset, choose another account, or explicitly enable that account’s credit spending.
 
 Stored-account vision and web-search helpers also recheck this policy before sending, including retries. If consent changes or a limit is reached after helper selection, the helper reports the policy refusal without sending that attempt. The standalone search relay returns a reset-bound 429.

+The Desktop relay's existing HTTP/HTTPS CONNECT transport now rejects malformed

+Decoded credential pairs are limited to 4096 UTF-8 bytes. If your selected proxy

 Only the proxy handshake carries proxy credentials. The raw upgraded socket remains opaque;

 before TLS-over-TLS negotiation. Test fixture CA trust is confined to child processes or
 injected test socket options, never the user's OS trust store.

+## Single-route opaque proxy transport
+
+`src/lib/opaque-proxy-tunnel.ts` establishes one HTTP/HTTPS CONNECT or SOCKS5/SOCKS5h
+route selected by `src/lib/desktop-upstream-tunnel.ts`. It returns a paused socket;
+the caller owns target selection and TLS, cancellation after establishment,
+backpressure, half-close and final destruction. The dialer has no proxy discovery,
+alternate-route list, direct fallback, listener, route version or session manager.
+The existing relay retains connection lifecycle ownership.
+
+The handshake is bounded by a timeout and optional caller signal. Proxy credentials
+are request-local and excluded from diagnostics. HTTPS proxy identity is verified
+against its configured host. HTTP Basic usernames with colons and malformed CONNECT
+response headers are rejected. Header size remains bounded even when a delimiter
+and early target bytes arrive together; remaining bytes are handed to the caller.
+
+`src/lib/socks5-handshake.ts` owns RFC 1928/1929 framing. Both SOCKS spellings use its
+remote-DNS behavior and existing zero-to-255-byte credential-field limits, including
+colon usernames. Bounded reads preserve coalesced opaque bytes after CONNECT.
+There is no retry or replay before or after establishment. The caller retains the
+fixed target, explicit DIRECT selection and whole-connection deadline described above.
+`tests/lib/opaque-proxy-tunnel.test.ts` and
+`tests/lib/opaque-proxy-tunnel-protocol.test.ts` cover framing, TLS, authentication,
+timeout, cancellation and half-close; `tests/lib/optional-desktop-upstream.test.ts`
+checks all four proxy schemes close cleanly when the production consumer sees EOF.
 
 Generic OAuth conversation ownership and request-local selection receipts follow [generic OAuth affinity](../providers/generic-account-pool.md#conversation-affinity).

From 6ccb47abea19b86889115d6bd81fcf1fa18181ef Mon Sep 17 00:00:00 2001
From: JUN <jun@lidgeai.com>
Date: Thu, 15 Oct 2026 23:29:16 -0700
Subject: [PATCH 57/72] fix(combos): carry OAuth combo cooldown, account
 rotation and health evidence fixes (#7191, #7204, #7187, #7209, #7175, #7185,
 #7193, #7197, #7198) (#7224)

Carried from #7191, #7204, #7187, #7209, #7175, #7185, #7193, #7197, #7198 (one commit per source PR, original author preserved). Security review follow-up: the Anthropic 402 combo cooldown now validates the sending credential's ownership before cooling an account.

Remote validation (hosted GitHub Actions unreliable; local tests not run by maintainer rule): union candidate codex/prr-integ-8 = dev c03eafd + #7224 + #7223 + #7225 + #7217 + #6454 + #6594 plus a Gentle Shell import-cycle fix (integ-9 e1f289c: typecheck + full suite on mini (Windows) and lidge (Linux), compared with the same host's dev runs) and a test-only Windows path-escaping fix for the reasoning-retention routing test (integ-10 0d4cba7, tree a2b309a: that file re-run on both hosts).

Async readers wait for the build; the routing-time sync entry never does and throws `RequestHistoryIndexBusyError`, which health scoring reads as unknown evidence. Health scoring (`src/routing/health.ts`) counts physical sends only: a request answered locally or refused before any send is no evidence for any target, and a row's terminal status and close reason score its last physical send, so a 200 stream cut mid-flight after a failover counts against the target that dropped it (`tests/server/health-scoring.test.ts`). A close discards the build, rejects waiting readers with `RequestHistoryIndexClosedError`, and removes the build files only after the worker thread exits. For 30 s after a worker build fails (other than on a replaced ledger), async readers and manual rebuilds rebuild inline instead, while routing-time reads keep reporting busy.
 Ledger revisions in `src/usage/log.ts` capture device/inode identifiers from bigint descriptor stats as exact decimal strings; history metadata, ingestion, cooperative scans and retention compare them without narrowing to Numbers, preserving distinct NTFS identifiers above 2^53. An older index containing a rounded identifier fails the identity check and rebuilds once. `src/usage/summary.ts` turns that file into the `/api/usage` shape — totals, daily zero-filled
 grid, model and provider breakdowns, and `measured / reported / unreported / unsupported / estimated` counts. Each scope also aggregates end-to-end output throughput (#6309): measured output tokens and wall-clock `durationMs` are summed over attempts reporting both, exposing `throughputTokensPerSec` — a token-sum-over-duration-sum, never a mean of per-request rates. `throughputSamples` counts qualifying attempts (legacy rows without attempts contribute one); nonpositive or nonfinite tokens/timing are excluded. The Usage summary and Models/Providers tables display the rate and sample basis, or unavailable when none qualify.
 All three throughput displays use the same finite-number guard as their tooltip; malformed or nonfinite rates are unavailable rather than formatted.

Cooldown entries in `src/combos/failover.ts` retain the failure status. The quota-only snapshot query records target/expiry pairs for unexpired 429/402 cooldowns using only cooldown map lookups. Its config-aware wrapper in `src/combos/resolve.ts` applies the picker's provider availability and cached quota checks before dispatch; request eligibility runs lazily only when exhaustion considers a 503, with throwing checks treated as ineligible. Responses exhaustion uses this evidence under the [failover contract](transports/responses-failover.md); ordinary cooldown selection and timing stay unchanged. A zero-attempt `combo_unavailable` names why each target was skipped. `comboExclusionReasons` in `src/combos/resolve.ts` derives one coarse label per target from the picker's own checks, in picker order: `provider missing`, `provider disabled`, `quota exhausted`, `cooldown <n>s`, then `ineligible for this request` when the caller's eligibility predicate refuses it or throws. `NoAvailableComboTargetsError` and `comboUnavailable` append them to the message; the label carries only the configured provider/model, never account, credential or request data. Coverage: `tests/responses/responses-combo-exhausted-error.test.ts`.

 # Responses Failover And Replay
 
 Combo `metered` eligibility follows the [runtime consent contract](../runtime.md#request-local-target-compatibility), including recovery selections. In `src/server/responses/run-turn-execution.ts`, streaming and buffered pre-output failures retain structured adapter status/type/code via `adapterFailureFromEvent`, and `formatErrorResponse`'s `classified` option keeps that verdict in the child body instead of re-deriving it from the status, wherever its type and message add nothing to what the status alone says; a verdict read from the message (quota, credentials, cyber policy, context overflow, catalog size) still outranks a generic adapter code, and spend-ledger, cyber-policy and replay-refusal overrides still win, and `consumeComboFailure` re-applies the client allowlist. Spend-ledger storage refusal remains 503. This preserves an exhausted subscription chain’s 429 response, a child's `insufficient_quota`, and the cool-free hop on `unsupported_input_modality` in `src/combos/failover.ts`. Coverage: `tests/adapters/anthropic/anthropic-subscription-chain.test.ts` and `tests/responses/responses-combo-run-turn-classified-failure.test.ts`.  `src/server/responses/request-transport.ts` resolves the final Anthropic model ID once for each enabled-pool request and holds its model route through admission. The three account-refusal retry sites in `adapter-dispatch.ts`, `adapter-continuation.ts` and `sidecar-execution.ts` use the same route, keep the original refusal if no replacement exists inside it, and preserve existing send and output replay limits. A local cooldown returns 429 with the earliest known Retry-After among accounts the route can use when they recover, and answers a usage limit when every held account is on spent quota ([quota exhaustion answer](../providers/anthropic-account-pool.md#quota-exhaustion-answer-and-fresh-read-recovery)); explicit fallback includes usable ordinary-pool accounts even when the saved route IDs have been removed, while a strict route stays route-scoped. Selection, refusal and 429-rotation logs use the rule’s 1-based `route:#<n>` position, never its name.

Classified account-entitlement 403 recovery and combo 402 credit-refusal cooldowns follow the [Anthropic account-pool contract](../providers/anthropic-account-pool.md#account-entitlement-refusal-recovery); combo error normalization preserves the original physical-send proof, and a stale credential cannot cool its replacement.

After an admitted Anthropic OAuth pool rotation, `adapter-dispatch.ts` rebinds reasoning replay to the committed credential snapshot; `adapter-continuation.ts` rebinds both its continuation clone and the outer request that persists the response. The replacement send strips the previous account's private state, while persisted ownership and the next turn follow the serving account. Codex alternate-account sends in `core-codex-account.ts` record `oauth-account-429` for quota recovery and `transient-5xx` for transient recovery, preserving the first response's wire status when sealing its attempt; gated-model moves keep their existing unattributed kind.
 Adapter construction remains with the existing registry; `fetch-helpers.ts` remains a leaf. For Kiro OAuth with load settings, `request-transport.ts` acquires a lease on the admitted account and transfers it before a reactive replacement send; cancellation permanently fences the request holder so recovery cannot install a late lease after abort cleanup. `core.ts` and `core-lifetime.ts` release the lease on returned-body completion, error, or cancellation, outside the inner admission `finally`.

From a8d1bb8d14e075aadc638d238f3e2da6ef2c588c Mon Sep 17 00:00:00 2001
From: JUN <jun@lidgeai.com>
Date: Thu, 15 Oct 2026 23:29:34 -0700
Subject: [PATCH 58/72] feat(gui): carry Combo visibility, workspace panes,
 Windows picker and Gentle Shell (#7195, #6767, #6691, #7213) (#7223)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Carried from #7195, #6767, #6691, #7213 (one commit per source PR, original authors preserved). #4649 held for security review. Security review follow-up: the Windows picker relay binds only when picker activation or selected-profile recovery needs it.

Remote validation (hosted GitHub Actions unreliable; local tests not run by maintainer rule): union candidate codex/prr-integ-8 = dev c03eafd + #7224 + #7223 + #7225 + #7217 + #6454 + #6594 plus a Gentle Shell import-cycle fix (integ-9 e1f289c: typecheck + full suite on mini (Windows) and lidge (Linux), compared with the same host's dev runs) and a test-only Windows path-escaping fix for the reasoning-retention routing test (integ-10 0d4cba7, tree a2b309a: that file re-run on both hosts).

+```bash

+ocx integration client enable --client gentle-shell
+ocx integration client disable --client gentle-shell
+```
+
+Gentle Shell has a separate destination and rollback history from Pi. Only
+`providers.opencodex` is managed; other providers and preferences stay intact.
+Catalog changes refresh an already connected, unchanged block. An existing manually
+copied block is a conflict, not permission to overwrite it: inspect the preview and
+use the explicit overwrite confirmation only if you intend to replace it.
+
+The saved `home` in `~/.gentle-shell/config.json` selects the destination. A saved
+custom path wins; isolated/default mode uses `GENTLE_SHELL_HOME` or
+`~/.gentle-shell/agent`. `GENTLE_SHELL_CONFIG` selects an alternate launcher config.
+These environment variables must be set on the **OpenCodex process**, not just in a
+later shell. Selectors must be absolute paths; literal `~` and relative paths refuse.
+One-off `gentle-shell --home` flags cannot be discovered by a background proxy.
+
+Link mode or a home aliasing Pi refuses with a Pi-integration remedy; use **Connect → Pi**
+for that shared file instead. OpenCodex does not change launcher preferences. An
+unreadable/unsafe launcher config refuses; malformed JSON falls back to isolated,
+matching the launcher. If you move a connected home, disable it using its original
+selectors before reconnecting the new one. Restart Gentle Shell after a catalog update.

+axis-specific arrow keys and Home/End bounds. At viewport widths up to 760px, panes stack
+without separators or horizontal scrolling while the saved desktop split tree remains intact.

 Hub runtime admission counts pending create/resume starts as well as live handles against global and per-device limits; every outcome releases its reservation. Stop and shutdown reclaim late resumed handles before clearing ownership. Coordinator result size limits normalize both response text and success, so bridge and MCP callers receive consistent errors.
 
 Prompt HTTP admission returns 202 with the existing session/event cursor; tracked operations publish terminal status for polling and attach a rejection observer immediately. Reconnect/resume cannot publish ready while a turn is active. The dashboard prefers newer local event cursors over stale polling, favors authoritative polling on ties, retains unconfirmed draft text with an uncertainty notice, and never retries prompt POSTs automatically.

 listener, relays every other CONNECT target blind, and refuses unauthenticated clients, plain proxied HTTP (a 405 whose body names the NO_PROXY fix), and loopback targets. Because it can never serve loopback, the same env carries a `NO_PROXY` loopback bypass (`127.0.0.1,localhost,::1,0.0.0.0`); without it Claude Code sent local HTTP MCP traffic to the proxy and every such server failed (#6936). Apply appends only the missing entries to a user value and leaves a covering value (including `*`) alone; an owned block without the bypass classifies stale so the startup migrate repairs it, and a non-string value other than null is refused as `foreign_env` rather than rewritten. Because the key is shared, apply records `{ hadKey, previous, written }` in `<claudeConfigDir>/opencodex-no-proxy.json` (`src/claude/intercept/settings-no-proxy.ts`, no token), and removal restores `previous` only while NO_PROXY still equals `written`, preserving anything else. Restoration needs that receipt: one that could not be written leaves none, and removal then keeps the appended entries (the harmless direction); a removal whose settings write fails before committing tries to put the receipt back. The receipt lives exactly as long as its ownership episode: an apply from an absent block and every removal invalidate it first and fail closed (`unreadable`) when they cannot, and rollback restores it with the captured value. The per-install proxy token is stored owner-only under `<OPENCODEX_HOME>/claude-intercept/` (0600 plus a real per-user NTFS ACL on Windows, via `src/lib/windows-secret-acl.ts`, and re-pinned on every read-through `ensure`), and the settings file carrying it is written through the same hardened atomic writer. After a successful CONNECT bind, startup runs `migrateClaudeInterceptSettings` (`src/claude/intercept/settings.ts`), which rewrites an owned env that no longer matches — e.g. a pre-auth URL left by an upgrade — while never creating an absent env or touching a foreign one, so a service restart cannot strand clients on 407s. Migration uses the bound handle's port; a failed bind leaves settings bytes unchanged. `StartServerDeps.startClaudeInterceptProxy` forwards the runtime binder seam through `src/server/index/optional-listeners.ts`, letting tests bind real proxies on port 0 without probe-and-release races while production retains stable ports. Status/inspection reads the token without minting it; only apply and intercept startup create it.
 The TLS listener rewrites `POST /v1/messages` and `POST /v1/messages/count_tokens` to a loopback origin and dispatches them under the `claude-intercept` ingress; other paths relay to the configured upstream. One relayed path is extended: for the standalone CLI's picker catalog, the listener's `cliCatalog` hook (`src/claude/intercept/cli-catalog.ts`) merges opencodex rows into `GET /api/organizations/<org>/model_selector/cc` (or `/api/model_selector/cc`), touching only the `cc` surface and leaving Desktop's `ccd`/`code` surfaces to picker mode, and into the fallback `additional_model_options` of `GET /api/claude_cli/bootstrap`. Eligibility: the `cc` catalog is rewritten only for a CLI-classified `User-Agent` with `claudeCode.cliFirstParty` on, because Claude Code caches it on disk for every process and a Desktop-spawned process must not seed rows a plain `claude` cannot route; the bootstrap request carries no entrypoint and follows CLI intent alone. Rows come from `buildCliPickerModels` (`src/claude/intercept/picker-models.ts`), which uses Desktop 3P registry aliases because the CLI offers only Claude-shaped ids (an `ocx-claude-*` row renders "Update Claude Code"), and advertises only an alias the registry decodes back to the same route. `src/claude/intercept/cli-picker.ts` supplies them lazily on the first eligible request, persists the snapshot at `<OPENCODEX_HOME>/claude-intercept/cli-picker-models.json`, re-checks each persisted row against the live registry (its alias must still decode to its recorded route; a cold registry after a restart is awaited first, and a snapshot whose rows still do not decode, for example after a provider change, is rebuilt within the same bound), and bounds a cold build at 2.5 s while awaiting the shared registry build in `src/claude/desktop-3p-startup.ts` that startup also uses (a failed or empty on-demand build is not retried for 30 s). Both CLI catalogs obey the shared [picker rewrite bounds](clients/claude-desktop.md#picker-catalog-rewrite-bounds), preflighting row growth before copying and keeping the final JSON within 16 MiB. The rewrite fails open: a provider error, non-2xx status, unparsable body, or no added row relays the upstream bytes unchanged; a body over the 16 MiB cap is cut off while streaming and answered 502 rather than buffered. Claude Code trusts its cached `<claudeConfigDir>/cache/model-catalog/*-cc.json` for about an hour, so `writeSettings` in `src/claude/intercept/settings.ts` and every successful `reconcileClaudeFirstPartySettings` drop those files (leaving Desktop's `*-ccd.json`); running sessions keep their list until restarted.
 The pair is on by default on a hub (`claudeCode.intercept.enabled`); its proxy port defaults to public port + 100 (`claudeCode.intercept.port`). The lifecycle records bind failure, and stop joins both sockets. Its serialized `ensure()` joins pending startup, reuses the live config and dispatch wrapper, and can start a previously unbound pair. `stop()` refuses future ensure calls and awaits an in-flight start. Local management applies and `ocx claude intercept start` (`POST /api/claude-intercept/start`) use this seam through `src/server/index/optional-listeners.ts`; hub-management ingress and data-plane credentials cannot start interception. Status reports `interceptReason` (with `interceptFailurePort` for a CONNECT bind failure) and optional `pickerReason` (with `pickerFailurePort` when the Desktop picker relay port is occupied), distinguishing disabled routing, client role, ephemeral public ports, occupied CONNECT ports and other failures. A changed configured port never rebinds a running pair: apply reports `port_mismatch` with both ports. With an ephemeral public port (`startServer(0)`), an explicit intercept port is required. The lifecycle makes a best-effort legacy picker-key cleanup attempt before checking client role, disabled routing/interception, or an ephemeral public port. Each new unbound lifecycle `ensure()` attempt retries cleanup; management requests rejected before that seam do not invoke it. Cleanup failures do not change the eligibility result or block startup. Direct `startClaudeIntercept` callers retain the same cleanup defense. Mock-only regression coverage lives in `tests/claude-integration/claude-intercept-cleanup.test.ts`.
-This ingress honours first-party model bindings (`claudeCode.intercept.modelMap`); see [Claude Desktop](clients/claude-desktop.md#first-party-model-bindings). Picker mode and the primitive's optional `allowedTargets` restriction are described under [Desktop egress proxy](clients/claude-desktop.md#picker-mode-the-desktop-egress-proxy). The macOS picker reuses an exportable signing identity protected by the OS credential store across normal restarts, without a plaintext key in the config directory. Restore verifies the constrained CA and current OS trust without installing trust; explicit picker `on` or `trust` grants missing or revoked trust. Legacy migration cleanup may still require consent, and native keychain unlock or application-access prompts are separate. Windows and Linux start no picker CA, credential-store or proxy work; the main intercept pair and best-effort legacy-key cleanup remain available.
+This ingress honours first-party model bindings (`claudeCode.intercept.modelMap`); see [Claude Desktop](clients/claude-desktop.md#first-party-model-bindings). Picker mode and the primitive's optional `allowedTargets` restriction are described under [Desktop egress proxy](clients/claude-desktop.md#picker-mode-the-desktop-egress-proxy). The macOS and Windows picker reuses an exportable signing identity protected by the OS credential store across normal restarts, without a plaintext key in the config directory. Restore verifies the constrained CA and current OS trust without installing trust; explicit picker `on` or `trust` completes the missing trust step, including the Windows confirmation when needed. Windows trust subprocesses are terminated on timeout or output-read failure; those failures remain distinguishable. Legacy migration cleanup may still require consent, and native macOS keychain unlock or application-access prompts are separate. Linux starts no picker CA, credential-store or proxy work; the main intercept pair and best-effort legacy-key cleanup remain available.
 
 `src/claude/intercept/client-class.ts` classifies each request by its Claude Code `User-Agent` entrypoint: `claude-desktop`, `claude-desktop-3p`, and `local-agent` are Desktop; other well-formed `claude-cli/<v> (external, <entrypoint>)` values are CLI; absent or malformed values are unknown.
 Only a client with its own first-party intent enabled (Desktop mode or `claudeCode.cliFirstParty`) enters the router for Messages paths; other paths use the configured upstream relay.

From 300e4265694530a75d27b994eb2206a309b7e7e7 Mon Sep 17 00:00:00 2001
From: JUN <jun@lidgeai.com>
Date: Thu, 15 Oct 2026 23:29:53 -0700
Subject: [PATCH 59/72] fix(claude): carry translated-lane server tools,
 refusal/cap/TTL fixes and usage metering (#7194, #7201, #7176, #7177, #7178,
 #7179, #7199, #7202, #7189, #7190, #7200) (#7225)

Carried from #7194, #7201, #7176, #7177, #7178, #7179, #7199, #7202, #7189, #7190, #7200 (one commit per source PR, original author preserved). #7205 held: replay can relocate server-tool exchanges into an earlier assistant turn.

Remote validation (hosted GitHub Actions unreliable; local tests not run by maintainer rule): union candidate codex/prr-integ-8 = dev c03eafd + #7224 + #7223 + #7225 + #7217 + #6454 + #6594 plus a Gentle Shell import-cycle fix (integ-9 e1f289c: typecheck + full suite on mini (Windows) and lidge (Linux), compared with the same host's dev runs) and a test-only Windows path-escaping fix for the reasoning-retention routing test (integ-10 0d4cba7, tree a2b309a: that file re-run on both hosts).

 | `maxUpstreamBodyBytes?` | `number` | `0` | Opt-in ceiling, in bytes, on a serialized native Responses **passthrough** body. `0` or omitted disables it — no limit is inferred for any destination. When set, a built body above the ceiling is refused locally before the send: streaming turns receive a terminal `response.failed` / `context_length_exceeded` so the client compacts instead of resending, and non-streaming turns receive a `413` naming the size, the number of embedded `input_image` items, and roughly how many megabytes of image data they represent. Checked at every build and rebuild point, including OAuth-refresh replay and alternate-account retry. Translated adapter paths are not covered. There is deliberately no default: the only measured ceiling here belongs to the WebSocket transport, which already falls back to HTTP for oversized turns, so a default would refuse requests that currently succeed. Set it when your gateway has a known request-size limit and you would rather see an actionable local error than an opaque upstream failure. |
 | `maxInboundBodyBytes?` | `number` | `0` | Opt-in ceiling, in bytes, on a decompressed **inbound** data-plane request body — the mirror of `maxUpstreamBodyBytes` above. `0` or omitted keeps the built-in 256 MiB default. Raise it when a large-context session can no longer compact: Codex replays the whole history to the compaction model, so on the 922k-token opt-in window the compaction request is itself the one that crosses the limit, and the session is stuck at the only operation that would have shrunk it. Clamped to 1 MiB–512 MiB. The ceiling is not negotiable: the reader materializes the body several times over (wire bytes, decoded bytes, the decoded string, and the parsed object graph), so peak memory is a multiple of whatever is admitted, and an unbounded value would be a memory exhaustion lever. Applies to `/v1/responses`, `/v1/responses/compact`, `/v1/chat/completions`, and `/v1/messages`. The listener's accept size is fixed when the proxy binds, so a change takes effect on restart. A body above the limit is refused locally with HTTP 413 and `code: "inbound_body_too_large"`, which is deliberately distinct from the `context_length_exceeded` 413 a provider size refusal produces. |

The same module's `declaredAnthropicServerTools` reads the caller's typed `web_search_*` / `web_fetch_*` declarations unchanged; `src/server/claude-messages.ts` hands them to the Responses core out of body, like the native reasoning replay, and the core keeps them on `parsed._anthropicServerTools` only for `inboundWire: "anthropic"`, so the translated body and every non-Anthropic leg stay as before. `tests/claude-integration/claude-translated-server-tools.test.ts` covers the Anthropic wire, a third-party Anthropic-compatible endpoint and a GPT leg. The translated Messages lane preserves the caller's output cap for non-canonical Responses gateways; canonical ChatGPT parameter stripping remains in its adapter. An explicit operator `cacheRetention` wins; otherwise `src/claude/inbound.ts` selects long retention only when every declared caller breakpoint requests one hour, including nested content and top-level automatic caching. Mixed TTLs retain the default.
 
 `src/claude/outbound.ts` carries a Responses provider's own `encrypted_content` in an `ocxr1:` `nat` envelope (`src/responses/reasoning-envelope.ts`) only when the serving attempt has committed and `src/server/responses/core-replay.ts` supplied a durable destination and credential owner. The `nat.tag` HMAC binds the exact blob to that owner and the installation's persisted salt. `src/claude/inbound.ts` restores the blob and item id only for the same client-facing model; each route binding verifies the tag against its effective endpoint, including `responsesPath`, and generation-bearing credential, then removes a mismatch from both the raw reasoning item and the parser's thinking-signature carrier before send. Missing owner or tag fails closed, including direct-forward credentials and OAuth generation changes. Native Anthropic ingress projects away every `nat` on both native branches, dropping blob-only blocks and leaving signed or visible-text fields intact. A thinking block that closes before serving commit has no `nat`. Translated bodies that reason request `include: ["reasoning.encrypted_content"]`; a body without reasoning does not. Anthropic `sig` and `red` envelopes keep their existing behavior. `tests/claude-integration/claude-native-reasoning-provenance.test.ts` covers route ownership and native projection.

+A missing `usage.jsonl` returns a zeroed summary with 200 because a fresh install has no usage. Unmeasured requests remain distinct from measured zero through `measured / reported / unreported / unsupported / estimated` counts and their coverage totals. Cost estimates in `src/usage/cost.ts` price only `reported` or `estimated` usage, so a partly measured row is never given a confident, understated cost; per-row `pricedRequests` / `unpricedRequests` count a request once, unpriced when any attempt is unpriceable, while a usage-less attempt that made no physical send (`sendCount === 0` or `locallyAnswered`) or was refused with an HTTP status >= 400 before any output (no `streamAborted`, no `firstOutputMs`) is a known zero. A usage-less attempt whose response began, aborted, or has no error status may have been billed and stays unpriced.
 Normal dashboard pages use the document as their vertical scroller. In `gui/src/styles.css`, body horizontal overflow is clipped without creating a second scrollport; the mobile open-drawer state also locks document overflow. The shared sidebar stays viewport-height through the end of Codex and Claude account pages. `gui/tests/shared-scroll-browser.ts` checks the built entry and App styles with short/long content, both themes, desktop chrome, collapsed navigation and mobile widths. The Usage tab renders that shape and the main Dashboard shows its 30-day summary. The 200-entry in-memory `requestLog` is not the aggregation source; the JSONL ledger is. Usage table scrollports in `gui/src/styles-usage-workspace.css` contain absolute screen-reader captions so long tables do not extend the outer document beyond the report; `gui/tests/usage-scroll-browser.ts` measures that boundary and last-row reachability at desktop and mobile widths.
 Ledger read failures instead return `500 { error: "read_failed" }`. Shared GUI usage admission reads that body before classifying HTTP failure and also rejects the legacy HTTP-200 envelope, so every shared cache retains its last valid report rather than fabricating zero totals.

No beta header is added: both tools are GA. Each streamed `web_search_tool_result` becomes a `web_search_call_begin`/`web_search_call_end` pair (the query of its `server_tool_use` in the same response, hit URLs and titles, or `failed` for an error result), which the Claude outbound renders back as the same block pair; a search Anthropic defers beside a client `tool_use` has no result in that response and surfaces nothing, and the replayed pair is dropped by the inbound translation, so a result without `encrypted_content` never reaches Anthropic. A streamed `web_fetch_tool_result` opens and closes the same cell with `fetch` set (the fetched URL and Anthropic's result content, verbatim); the bridge records it as an `open_page` `web_search_call` carrying `fetch_result`, and the Claude outbound renders it back as `server_tool_use` `web_fetch` + that `web_fetch_tool_result`, not counted in `web_search_requests`.

Dotted Bedrock ids do not parse as a family, and the Messages-native passthrough forwards caller fields unchanged. `tests/adapters/anthropic/anthropic-sonnet-5-5-contract.test.ts` and `tests/adapters/anthropic/anthropic-haiku-5-5-contract.test.ts` pin the family table. |

The final wire compiler owns [endpoint-scoped tool-schema loss policy](providers/google.md#google-tool-schema-loss-reporting): compatible mode changes no request bytes, strict initial loss creates no physical send, and strict non-direct repair creates no changed repair send. A caller-declared strict tool selects `functionCallingConfig.mode: "VALIDATED"` in place of the absent-choice default; `NONE`, `ANY` and a forced-name choice are stronger constraints the caller asked for and are never overwritten. |
 | `src/adapters/unique-tool-call-ids.ts` | Request-scoped tool-call-id uniqueness for every `openai-chat` provider. An upstream that mints an id from the call's position in its response repeats `call-0-0` on every turn; a Messages client has already paired that id, drops the duplicate, and is left with a call that has no result, so the turn reads as empty and the model re-issues it indefinitely. Only a **repeat** is rewritten — the first occurrence stays byte-identical, leaving prompt-cache keys, reasoning-replay lookups and already-unique upstreams untouched. The ids to avoid come from the caller's history, captured in `buildRequest` (the only point that sees it) and applied at emission, never at ingestion: ingestion matches streamed deltas against the id upstream sent, so rewriting there would strip a pending call of its identity mid-stream. A repeat takes a `-<n>` suffix, never `_<n>`, because `<earlier>_<digits>` reads as a batch sub-call of `<earlier>`; occupied-set search resumes by suffix width and retained base prefix, including when siblings converge as `-9` becomes `-10`. Covered by `tests/adapters/openai/openai-chat-tool-call-id-remint.test.ts`. |

 Both search loops keep `web_search` declared after the search budget is exhausted. Further calls receive a paired limit-reached result without another physical search; at most `maxSearches + 3` model iterations run before a terminal error. Ordinary caller tools and cancellation still end the loop. Empty-answer recovery alone removes all tools. `src/web-search/loop.ts` makes at most one extra answer attempt after a clean forced-answer terminal with no visible output or tool call, only while an iteration remains. The recovery has no tools and reuses gathered search results. Malformed calls fail before refusal/truncation passthrough, and well-formed recognized refusal/truncation terminals pass through unchanged, including empty or partial answers. The extra generation may incur provider usage. `src/web-search/run-turn-loop.ts` shares this recovery and checks the ceiling before dispatch so it cannot start an unused request; below the search cap, `emptyCompletionRetry` permits one identical empty-answer retry per request with current tools and results. Errors and invalid terminals never authorize another search. Batched results from one call share one 8,000-character budget in `src/web-search/format-result.ts`, planned per query before serialization (#6621): every query keeps its label and status, shortened answers and unlisted sources carry markers with their original counts outside the untrusted boundary, structured output stays one valid JSON document, and a batch whose fixed parts alone overflow is condensed to status lines with a per-status count of any query that still did not fit.
 
 `src/web-search/loop.ts` uses `src/web-search/header-deadline.ts` to suspend the cumulative response-header deadline while each physical send awaits local pacing admission. Ordinary fetches, adapter executors, reset retries and pool-key rotations retain the remaining budget after admission; same-target 429 backoff still clears and restarts that budget. The default remains 200,000 ms. Client cancellation remains linked during queued admission and after final headers, and the existing pacing slot wrapper retains leases through body completion or cancellation. Streaming retry heartbeats and body inactivity deadlines keep their existing ownership. `tests/web-search/web-search-pacing-deadline.test.ts` covers queued success, real header stalls, queued cancellation, retry admission and cumulative rotation time. OpenAI sidecar 429 replays run only when their backoff fits the remaining sidecar deadline; otherwise the original 429 remains the routing-health outcome rather than becoming a timeout. Reset recovery and 429 replays share one three-send budget per search, so the two layers cannot multiply physical sends. Direct vision/search helpers and the alpha/search relay retain the resolver's live [stored-account credit policy](codex-account-controls.md#stored-account-authentication-policy) through physical sends and retries; a local hold prevents the send without becoming an upstream connection failure.
+
+### Loop usage accounting
+
+Every iteration re-sends the full context, so `src/web-search/loop.ts` adds the usage of each iteration whose terminal the client never sees (search-calling passes and the discarded empty answer) to what `onUsage` reports for the request log, including on an in-stream or translator-budget error; token and cache counts add, while `contextTotalTokens` and `rawUsage` come only from the final terminal, never an earlier iteration's. The client-facing terminal keeps the last iteration's usage, because Codex and Claude Code size the context window from it (`tests/web-search/web-search-loop-iteration-usage.test.ts`). A pass that ends in an adapter `error` event was billed too: `parseStreamWithProgress` hands that event's usage to `onErrorUsage` before failing, so `src/web-search/loop.ts` and `src/images/loop.ts` (which already puts its hidden iterations' usage on the failed terminal) add it to the usage they report, while the turn still fails with the same error (`tests/web-search/web-search-loop-error-usage.test.ts`, `tests/images/loop.test.ts`).
+
+A 429 rotation inside either loop splits the request into one attempt row per account, so the hidden usage already gathered belongs to the account the loop is leaving. Right after a rotation each loop offers it through `onRotatedUsage`; `src/server/responses/sidecar-execution.ts` accepts only when the next send will open a new attempt (`attemptAccountChanged`), binds it to the still-open attempt, and the loop drops it from what `onUsage` later reports, so the surviving attempt carries only its own rounds and nothing is counted twice. The image loop still puts the whole turn on the client terminal (`tests/web-search/web-search-rotation-usage-attribution.test.ts`, `tests/images/loop.test.ts`).

Subject: [PATCH 60/72] feat(responses): carry compaction capabilities and
 reasoning retention (#6759, #6930, #6603, #6758) (#7217)

Carried from #6759, #6930, #6603, #6758 (one commit per source PR, original authors preserved). Retention across account/model switches is opt-in and defaults off.

Remote validation (hosted GitHub Actions unreliable; local tests not run by maintainer rule): union candidate codex/prr-integ-8 = dev c03eafd + #7224 + #7223 + #7225 + #7217 + #6454 + #6594 plus a Gentle Shell import-cycle fix (integ-9 e1f289c: typecheck + full suite on mini (Windows) and lidge (Linux), compared with the same host's dev runs) and a test-only Windows path-escaping fix for the reasoning-retention routing test (integ-10 0d4cba7, tree a2b309a: that file re-run on both hosts).

+- `supportsNativeCompactEndpoint: true` opts key/local/forward routes into the separate v1 endpoint.

+- `decodesNativeCompactionBlobs: true` preserves native blobs on subsequent turns when there is
+  no known serving-provider mismatch. Neither generation flag implies this replay capability.
+
+Custom native v1 also honors `preserveResponsesReasoningContent: true` for plaintext reasoning
+input, just like ordinary custom Responses requests. Absent or `false` keeps content blank;
+OpenAI-operated compact destinations keep blanking even if the flag is set. Internal `ocxr1:`
+envelopes are always removed. Plaintext preservation is independent of the generation flags,
+native blob replay capability, and serving-identity checks.
+
+If the custom provider also requires adjacent tool results (`requiresAdjacentResponsesToolResults: true`),
+both ordinary Responses and native v1 remove opaque reasoning ciphertext and require plaintext replay.
+Missing `reasoning_text` is filled from the item's `summary_text`, or a minimal placeholder if no
+usable summary exists. Existing plaintext is preserved. OpenAI-operated compact keeps its own policy.
+
+For a gateway whose **v2 generation and replay** have both been verified, merge these fields into
+its existing provider configuration, retaining its real URL and configured authentication:

+```json
+{
+  "adapter": "openai-responses",
+  "supportsNativeCompactionTrigger": true,
+  "decodesNativeCompactionBlobs": true
+}

+### Reasoning retention during compaction
+
+Readable reasoning retention is an advanced, explicit opt-in and is **off by default**.
+Only `reasoningRetention.enabled: true` enables it; an omitted block, `enabled: false`,
+or legacy limits without `enabled: true` leave ordinary compaction behavior unchanged.
+When enabled for routed v1 `POST /v1/responses/compact` and routed v2 `compaction_trigger` requests, readable reasoning stays local while the selected
+model summarizes other context. After a readable summary succeeds, exact retained text returns
+alongside it in framed historical context messages, not as new assistant reasoning or instructions.
+Repeated compaction withholds those messages again. Ordinary subsequent turns replay them as history.
+
+```json
+{
+  "reasoningRetention": {
+    "enabled": true,
+    "maxContextPercent": 20,
+    "maxTokens": 100000
+  }
+}
+```
+
+Both limit fields are optional and, **when enabled**, default at runtime to `20` percent and `100000` estimated tokens.
+The effective limit is the smaller of the percentage of the compacting model's context window
+and the absolute token cap; when the context window is unknown, only the absolute cap applies.
+The estimate includes each retained message's historical-context frame, not just its reasoning text.
+Above the limit, readable text is written verbatim under the resolved OpenCodex home's
+`reasoning-archive/` (normally `~/.opencodex/reasoning-archive/`). The summarizer receives a
+path note instead of the text, and the finished readable summary includes a notice naming that file.
+New archives are private to the user on POSIX. An archive is provisional until a readable summary
+returns its path: failures, cancellation, invalid summaries, and opaque compaction responses remove
+the current attempt's file. Internal retries reuse it; previously successful archives are preserved.
+Failed compaction returns no replacement history.
+
+The percentage/token limits bound reasoning returned in context, **not cumulative archive storage**.
+Each archive contains only readable reasoning admitted in that request; request admission is bounded
+by `maxInboundBodyBytes` (256 MiB by default, configurable up to 512 MiB), plus small block separators.
+There is **no aggregate archive byte/file limit, automatic expiry, or background archive cleanup**.
+Successful archives remain until you manually delete their files, including after disabling retention
+or resetting the setting. They are plaintext, contain potentially sensitive conversation reasoning,
+and share the resolved OpenCodex home of that proxy instance. Deleting an archive makes any existing
+path notice unable to recover its contents; save anything you need first. A process crash or failed
+filesystem write/cleanup can also leave a provisional file requiring manual cleanup.
+
+**Dashboard → Overview → Advanced settings → Reasoning retention** provides the explicit switch
+and both limits; **Reset and turn off** removes the override and switches retention off. GET/PUT `/api/settings` exposes `reasoningRetention`: null clears the block,
+and omission preserves it. `enabled` must be a boolean when present. Percentages must be greater than 0 and at most 100; token caps must
+be positive integers, and unknown fields are rejected. Invalid hand edits disable only this
+block with a warning, keeping unrelated providers and settings.
+
+Private provider ciphertext and signatures are not decrypted or copied into portable retained
+messages. An upstream native opaque compaction response retains its exact output item and
+ciphertext, without added retained messages or a rewritten summary. Native compact endpoints
+keep their existing behavior.
+
+Routed v2 still returns exactly one compaction item. Its proxy-owned `ocx2:` envelope stores
+the summary and retained historical reasoning separately as JSON/Base64; this is encoding,
+not provider encryption. Subsequent requests restore separate historical messages, and
+repeated compaction withholds the reasoning again. Old `ocx1:` summaries remain supported.
+Opt-in emergency compaction recovery also preserves this separation for JSON and SSE.
+Explicit native-history recovery restores separate summary and historical reasoning messages too.

+## Codex-native ordinary Lite hosted-search history
+
+Ordinary requests retain structural hosted-search history by default, including Responses Lite requests. To opt in to lossy reference notes, set `providers.openai.projectResponsesLiteHostedSearchHistory: true` in `config.json` (an actual boolean, not the string `"true"`). The per-provider setting defaults to off; omission or `false` keeps structural history. Even when enabled, projection applies only to ordinary requests whose final destination is exact canonical ChatGPT Codex `/responses` and whose effective request intent explicitly selects Responses Lite. It converts unreferenced remaining `web_search_call` history into labeled assistant reference notes. The final `x-openai-internal-codex-responses-lite` header selects Lite only when its value is exactly `true`; an explicit `false` overrides frame metadata. Without a recognized header value, a valid string-map `client_metadata.ws_request_header_x_openai_internal_codex_responses_lite` value of `true` is used, matching the existing WS metadata handling. Non-Lite or unrecognized effective intent retains structural history; malformed metadata does not override an explicit HTTP `true`. Model names, subscription authentication, missing hosted declarations and `additional_tools` alone do not select this policy; no header or metadata is rewritten to make it apply. Once enabled, it applies to new threads/forks, cross-model continuations and cache misses/restarts, without diagnostic settings. Only a valid same-scope bridge memo proves an original function call/result that can be restored first; an ID prefix, model name or missing memo cannot determine the issuer. A hosted cell exactly referenced by a same-input `item_reference.id` is retained. `store:false` removes references earlier, and its remaining hosted history can be projected. Tool declarations/Lite `additional_tools`, choices, client call/result pairs, reasoning/native ciphertext, non-hosted order and caller raw history retain their existing contracts.
+
+Within that opted-in Lite boundary, this is an explicit **lossy history policy**, not a claim that hosted calls are invalid schema or that all upstream errors are fixed. Notes carry untrusted status/action metadata and allowlisted URL/title/type from both action and top-level sources, never instructions or fetched page bodies: 2,048 UTF-16 units per string, 20 entries per list, 65,536 serialized bytes for all projected notes, then an omission note. IDs and unknown fields are dropped from converted cells. HTTP/SSE and WS share the final ordinary builder.
+
+Public OpenAI API and other destinations do not gain ordinary or native-compact projection. Native `/responses/compact` remains its existing endpoint/account-scrub/official opaque-output path and retains structural hosted history. Portable/routed summaries reuse their existing projection trigger and default reference behavior; the shared renderer additionally retains allowlisted top-level sources there. No new retry, source classification or compaction summarizer is introduced.

 重放的推理項攜帶的 `encrypted_content` 只有產生它的供應商與憑證才能讀取。若 opencodex 知道該對話上一次由另一個供應商處理，它會在送出前移除這個 blob，並保留該項的摘要。若那個供應商還使用了不同的 endpoint 或憑證，該項的 `rs_…` id 也會被移除，因為它指向新目標查不到的項目。若 opencodex 無從得知，例如代理重新啟動之後，新目標會拒絕這個 blob：OpenAI 與 Azure OpenAI 回傳 `400 invalid_encrypted_content`。此時 opencodex 會去掉上一個供應商的推理狀態（blob 與 `rs_…` id）後只重送一次請求；保留 id 會導致 `Item with id 'rs_…' not found`。
 
 這項復原適用於所有使用 Responses 協定的 adapter，因此 `openai-responses` 與 `azure-openai` 的行為相同。復原成功後，該對話在同一目標上的後續輪次會在接下來五分鐘內於首次送出前移除這些狀態。重送計入請求的一般傳送預算。一般的 400 與 429 不會以這種方式重送，5xx 也不會，只有一個狹窄的例外：對於攜帶加密工具輸出的請求，回應本文恰好是該解密拒絕的 502 會得到同樣的一次重送。第二次拒絕會原樣回傳給客戶端。遇到這種情況，請在目標供應商上開始新的對話。

 Pasted GCP JSON persists only as `gcp-sa:<account>` references in one pool transaction in `src/providers/api-keys.ts`; post-commit deletion follows [Vertex credential markers](providers/google.md#vertex-credential-markers).
 `src/config/schema/leaf-validators.ts` accepts only boolean `apiKeys[].allowMeteredComboTargets`; malformed entries are dropped rather than promoted. `src/types/config.ts` and combo validation define optional boolean target `metered`, normalized false when omitted, and optional per-combo `allowMeteredTargets` (default false, literal boolean validation shared by config schema and management API). Explicit consent is required under the [combo runtime contract](runtime.md#request-local-target-compatibility). Model-price overrides follow the [pricing contract](pricing.md). Quota activation reuses the existing next-reset fields without adding a polling configuration key. See the [quota activation contract](providers/openai-tiers.md#public-provider-contract). `src/types/config.ts` defines `anthropicAccountPool.routes` as ordered model rules. `src/oauth/anthropic-model-routes.ts` validates bounded names, full case-sensitive globs and stored account IDs; `src/config/diagnostics.ts` rejects malformed candidate writes. Load retains a malformed hand edit so unrelated providers survive, while the enabled Anthropic selector refuses it locally before dispatch. Saved rules remain inert when the pool is disabled; affinity is process-local. Request logs use only the rule’s 1-based `route:#<n>` position, never its configured name. `src/cli/hub-disable.ts` removes interdependent hub/loopback/role/hostname settings through `mutatePersistedConfig` and `validateConfigCandidate` in one commit. Top-level deletion intent uses `src/config/rebase-provenance.ts` and authoritative disk provenance in `src/config/live-reconcile.ts` to preserve removed hub bindings through later live saves, `src/config/live-topology.ts` keeps an independent active-topology baseline and merges desired next-start settings into a separate persistence projection, retaining actual socket identity and live hub/client topology during guarded saves and OAuth disk adoption. Client connections and runtimeRole remain one topology unit through connect/disconnect, including fresh disk-only connections. Disk additions/value updates and deletions all survive repeated saves without changing active topology. `src/config/api-key-reconcile.ts` merges key rows by stable ID under the existing save lock; either side's revocation defeats stale edits while disjoint names and rotations merge; unchanged live key membership/order adopts persisted ordering. `tests/config/hub-disable-live-save.test.ts` exercises disable followed by live key creation, rename, rotation, unrelated settings and repeated saves. Saved API keys have no immutable enrollment marker; explicit exact-ID revocation preserves all unselected keys.

+Custom Responses providers may declare independent boolean `supportsNativeCompactionTrigger` and `supportsNativeCompactEndpoint` capabilities in `src/config/schema/leaf-validators.ts`; absence remains off. They do not imply `decodesNativeCompactionBlobs`, official identity, or credential authority; custom native v1 key/local/forward replay enforces the separate blob capability and known serving-identity changes, while OAuth retains routed credential resolution. The native gateway contract and regression are in [Responses transport](transports/responses.md) and `tests/responses/native-compaction-gateway.test.ts`.
 `src/config/schema/config-schema.ts` validates the optional `preferModelAliasIds` flag as a boolean; malformed disk values disable this raw-list projection without rejecting providers. It defaults off. Custom Responses providers can explicitly enable `preserveResponsesInputItemIds` and `preserveResponsesMessageMetadata`; both default off and accept only booleans. The [replay sanitization contract](transports/responses-wire-shapes.md) keeps ordinary destinations unchanged and preserves xAI custom-call ID repair. `src/config/schema/compaction-recovery.ts` strictly validates opt-in `compactionRecovery`; invalid disk values disable it with a warning, while candidate writes reject them. `src/config/schema/blocked-model-redirects.ts` applies the same read-degrade/write-reject boundary to malformed `blockedModelRedirects` maps. The [failure-only contract](transports/responses-failover.md) leaves provider identity, accounts and client compaction unchanged. Optional `desktopCompatibility: { startOnProxyStart: boolean }` likewise rejects invalid writes and degrades invalid disk values to off; it saves neither certificate consent nor correction mode. Its field-scoped dashboard writer adopts committed state into the live comparison baseline; see [Codex Desktop startup](clients/codex-desktop.md#proxy-startup-preference). `src/cli/config-command.ts` accepts one leading UTF-8 BOM when parsing validate/import input from a file or stdin. JSON syntax and schema validation still run before persistence; BOM characters inside string values remain data.

The former retains received skills instructions for a conversation; the latter passes through the current catalog.

This is separate from Codex's `skills.include_instructions` TOML switch and does not change the live dashboard probe. See the [Responses snapshot contract](transports/responses.md#responses-httpsse). Optional `reasoningRetention` is advanced and off by default: only explicit boolean `enabled: true` activates it, so omitted/false/malformed and legacy limit-only blocks stay off. When enabled, it accepts `maxContextPercent` (>0, <=100; default 20) and `maxTokens` (positive integer; default 100000), using the smaller limit for [routed v1/v2 compaction](transports/responses-failover.md#compaction-routing-overrides). An unknown context window uses the absolute cap only. Malformed disk values degrade only this block with a value-free warning; candidate writes reject them before the load schema's catch. Absence remains unpersisted, and native/opaque protocols are unchanged.
 
 Google providers may persist `googleToolSchemaPolicy` as `compatible` or `reject-lossy`.
 `ocx provider add --google-tool-schema-policy` is one authoring path and is accepted only when the effective adapter is `google`. Omission remains absent in `config.json`; the adapter resolves it to `compatible` in memory. Provider live lifecycle, pacing and public editor CAS are described in [CLI management](cli-management.md#provider-live-operations-and-bounded-editor-input); local auth/path additions retain canonical OpenAI validation before saving.

Absent is the default and means observe-only accounting: spend is still journaled and nothing is refused, so observe-only and enforced servers take the same state-directory writer lease. One live process may write one directory; explicit sibling instances need separate `OPENCODEX_HOME` directories. There is no default figure for any scope — the ledger is on by default, so a shipped ceiling would refuse real traffic on upgrade against a number nobody chose. Strictly validated and positive-integer only, because 0 would read as a budget and refuse everything; a malformed section degrades to no ceiling, which is why the write path rejects it and load diagnostics report it. Top-level `spendPoolAliases` is preserved verbatim on load; malformed mappings leave ceilings intact and refuse pool admission, while candidate writes reject them. Current provider IDs automatically own their ordinary salted pool buckets at read time; other historical labels need explicit mappings or remain conservatively unbound. Neither self-bindings nor explicit mappings persist as journal links. Padded destinations and destinations absent from the provider roster are rejected on write and warn/refuse pool admission on load. `src/lib/spend-pool-alias-validation.ts` checks the existing home salt without creating it and rejects a configured provider’s own pool alias mapped to a different provider, including when providers are added later. Live provider and full-config adoption call `reconcileLiveStateStores` in `src/lib/state-store-registrations.ts` to refresh this policy from the active roster; detached config reads do not change it. It stays outside the legacy strict `spend` object. Resolution and application live in `src/lib/spend-reservation-ledger.ts`; see [historical continuity and rollback](transports/responses-spend.md#historical-pool-continuity-and-rollback). |

 | Combos | Rail, detail panel, and an add flow (`gui/src/components/ComboWorkspace.tsx`). |
 | Add provider | Catalog browser plus form and OAuth panes (`gui/src/components/provider-catalog/`, `gui/src/components/AddProviderModal.tsx`). The catalog browses four tabs — Accounts, Free, Local, Paid — where Local is a catalog-only bucket peeled out of `bucketPresets` after `presetTier` has classified; the workspace `providerTier` stays three-way, so the rail, the free-paid sort and the Free count still treat a local runtime as free. Search sits above the tabs and reaches every tab at once: while a query is live the list renders all four groups with headings and the strip becomes jump chips with counts rather than a tablist, because moving the selected tab would change the row kind under the user (a preset-select button becomes a login row). ArrowDown from the search input focuses the first enabled result action; if none is available, focus stays in the input. The tab strip wraps within narrow modals. Every nonempty note has a full-text button so narrow rows never hide content permanently; the native note dialog closes during teardown and restores focus to its trigger. Provider notes clamp to two lines and open in full in a stacked native `<dialog>` owned by `AddProviderModal`, which also owns the search text so its `window` Escape handler can unwind popup, then query, then dialog. |
 | Codex accounts | Account pool cards, add-account flow, switch and reset modals (`gui/src/components/CodexAccountPool.tsx`, `gui/src/components/AddCodexAccountModal.tsx`), plus the generic account-targeting picker opt-in on `gui/src/pages/codex-set-multiauth.tsx`. Add/delete/login completion is projected to one boolean before presentation; pending catalog work is a warning, not a failed account mutation. The main card's native-main device reauth (#3898) is owned by `gui/src/components/use-main-device-reauth.ts`: the dedicated `/api/codex-auth/main/reauth-device` namespace only — never the pool login route — with flowId-owned polling, an allowlisted verification URL, and no token fields accepted from payloads. The main-device reauth hook retains flow ownership from the Cancel click, while DELETE is unresolved and after retryable failure; polling normally continues. A concurrent GET HTTP error cannot expose a replacement login POST before DELETE settles. If a retryable DELETE failure races with a non-2xx GET while the flow is pending or committing, either response order preserves same-flow Cancel retry, restores the last server-provided device code, verification URL, and phase when needed, and keeps the existing poll cadence so a later terminal result remains observable. Outside same-flow cancellation ownership, a GET HTTP failure still stops polling without starting a second login POST. The cancellation-failure indication survives pending status updates until a trusted terminal result releases ownership. A successful DELETE with a terminal `failed` DTO releases it and uses the same closed failure-code mapping as polling; only `succeeded` notifies login completion. Unrecognized or nonterminal DTO status values remain retryable. A DELETE response with HTTP 404 and code `unknown_flow` releases the expired flow and shows the existing generic failure state so device re-login is available again; it claims neither login success nor confirmed cancellation. Confirmed cancellation also makes device re-login available. Start, polling and cancellation completions verify their controller or flow ownership after asynchronous response reads; replaced flows and unmounted hooks cannot update a newer flow or notify completion. Effect setup restores mounted state after the StrictMode development cleanup cycle. |

Its scope is the [routed v1/v2 compaction contract](transports/responses-failover.md#compaction-routing-overrides); opaque output stays unchanged. `tests/config/settings-reasoning-retention.test.ts` and `gui/tests/reasoning-retention-panel.test.tsx` cover the API and controls. Inputs expose invalid state and reference the validation alert only for the failing field. |

+# ADR-6930 — decision recorded under "Hosted-search continuation binding"
+
+- Contract owner: [providers-and-adapters.md](../providers-and-adapters.md#hosted-search-continuation-binding)
+
+## Decision record
+
+- Purpose and intent: Let an explicitly selected Codex Responses Lite continuation carry useful metadata from old hosted-search history when there is no same-scope bridge call/result to restore.
+- Prior constraints and evidence: Official Codex 0.161.0 omits hosted model tools on its Lite path and can expose client-executed `web.run` through standalone search. It still defines and replays `WebSearchCall` history. The report in [openai/codex#51962](https://github.com/openai/codex/issues/51962) records a successful default new Sol conversation, failure compacting restored hosted history, success after removing those hosted cells, and a raw hosted-history request that succeeds when the matching hosted tool is declared. This supports a Lite/history compatibility problem, not a universal hosted-schema ban or proof that every ordinary Lite request fails. Public Responses documentation continues to describe [hosted web-search output](https://developers.openai.com/api/docs/guides/tools-web-search#output-and-citations).
+- Alternatives considered: Keep the original all-canonical ordinary projection; infer Lite from model names, subscription authentication or absent hosted declarations; require a separate provider opt-in; or narrow the existing policy to explicit current-request Lite intent. A narrower action/query repair would retain more structure but cannot represent an old hosted call as a client-executed Lite tool.
+- Chosen approach: The contributor narrowed ordinary projection to the existing exact canonical ChatGPT `/responses` destination and explicit Lite intent after bridge restoration and normalization. The final HTTP header's literal `true`/`false` wins; otherwise literal `true` in valid string-map frame metadata is the fallback, matching existing WS preparation. Missing, non-Lite or unrecognized effective intent keeps structural hosted history. No transport signal is created or rewritten by this decision.
+- Reason for this choice: The current request supplies a protocol-specific boundary without guessing where historical cells originated or assuming every model/account uses Lite. Keeping non-Lite and unknown requests structural avoids imposing a lossy policy on compatible hosted-tool continuations. Compared with a new provider switch, the existing Lite signal ties the repair to the client's selected protocol; it does not prove that loss is necessary for every Lite request.
+- Consequences and limitations: Lite still defaults to lossy, bounded, untrusted reference notes for unreferenced remaining hosted cells. Same-input references and same-scope bridge restoration keep their existing exemptions/order; public API, native compaction and portable/routed summary triggers are unchanged. The original renderer enhancement preserves allowlisted top-level sources in portable summaries as well. This record explains the contributor's authorized narrower implementation, not project-owner acceptance or readiness. Fixture tests establish serialization behavior only; live ordinary HTTP/WS acceptance, all upstream errors and backend policy remain unverified.
+- Fixed-source references: [Lite hosted-tool exclusion](https://github.com/openai/codex/blob/979011409de0a60b52f179721948e65531d26144/codex-rs/core/src/tools/spec_plan.rs#L622-L651), [native WS Lite metadata](https://github.com/openai/codex/blob/979011409de0a60b52f179721948e65531d26144/codex-rs/core/src/client.rs#L822-L835), [HTTP Lite header](https://github.com/openai/codex/blob/979011409de0a60b52f179721948e65531d26144/codex-rs/core/src/client.rs#L2345-L2354), and [hosted history replay](https://github.com/openai/codex/blob/979011409de0a60b52f179721948e65531d26144/codex-rs/core/src/context_manager/history.rs#L1015-L1036).

+# ADR-6931 — decision recorded under "Hosted-search continuation binding"
+
+- Contract owner: [providers-and-adapters.md](../providers-and-adapters.md#hosted-search-continuation-binding)
+
+## Decision record
+
+- Purpose and intent: Require an explicit provider opt-in before ordinary Codex Responses Lite requests lose structural hosted-search history.
+- Prior constraints and evidence: ADR-6930 records the contributor's earlier Lite-intent boundary and its unverified live acceptance. The [project owner's review requirement](https://github.com/lidge-jun/opencodex/pull/6930#issuecomment-6188875868) requires default-off configuration before review because that lossy ordinary behavior must not become the default before live acceptance.
+- Alternatives considered: Keep projection on for all explicit Lite requests; remove ordinary projection entirely; or add a provider switch without retaining the existing destination and Lite gates.
+- Chosen approach: Add optional strict boolean `providers.<name>.projectResponsesLiteHostedSearchHistory`, default off. The final ordinary builder projects only when its selected provider value is exactly boolean `true`, the final URL is exact canonical ChatGPT Codex `/responses`, and the final request explicitly selects Lite under the existing literal-header/valid-string-map-metadata precedence. Omission, `false`, and malformed runtime values do not enable projection.
+- Reason for this choice: Operators can explicitly evaluate the existing lossy policy while ordinary Lite requests keep structural history by default. Provider intent supplements the current protocol and destination boundaries without inferring historical issuer, model capability, or live acceptance.
+- Consequences and limitations: Bridge restoration still runs first; same-input references still exempt their hosted cells after existing `store:false` handling. Opted-in notes retain the existing untrusted bounded metadata contract. Native compact, public API and other destinations remain unchanged; portable/routed compaction projection retains its existing triggers and defaults. The switch neither selects Lite nor changes headers, metadata, transport, diagnostics, retries, or the summarizer. Fixture validation does not establish ordinary live HTTP/WS acceptance or resolve all upstream errors. ADR-6930 remains historical and is not rewritten.

Its client delivery shapes in `src/chat/outbound.ts` and `src/server/chat-native-sse.ts` relay the upstream `service_tier` echo on non-stream, folded-stream, and synthesized-SSE bodies, never inventing the key when the upstream omits it. |
 | `src/adapters/anthropic.ts` | Anthropic Messages bridge. A `refusal` or `content_filter` stop reason yields an explicit `incomplete` event with `retryable: false` rather than `done` with that stopReason (#4312); `max_tokens` remains `done`. For a Responses client the bridge delivers that event, and the same one from the Kiro adapter, as a terminal `response.failed` ([Adapter-to-Responses bridge](transports/responses.md#adapter-to-responses-bridge)). It is the wire that defines `tools[*].strict` and `tools[*].allowed_callers`, so a rebuilt declaration carries both: an explicit `strict: true` and any `allowed_callers` the caller declared. An absent `strict` stays absent, because the Messages inbound records it as `false` and a `false` on the wire would read as an opt-out nobody asked for. Anthropic Fast uses the native `anthropic-speed` FastWire: a set decision sends `speed: "fast"` with `fast-mode-2026-02-01` in one case-insensitively merged, deduplicated `anthropic-beta` header that preserves OAuth betas. Stream and buffered `usage.speed` echoes confirm fast or downgrade to standard; no echo leaves the request assumed. `tests/adapters/anthropic/anthropic-fast-speed.test.ts` pins the wire and echoes. Anthropic Fast is opt-in: the registry marks both Anthropic entries `fastOptIn`, and `src/providers/fast-opt-in.ts` (`providerFastSwitchOff`) keeps Fast off until `providers.<name>.fastEnabled` is `true`. An off switch is provider capability `false`, applied in the FastPolicy authority (`service-tier.ts`), `resolveModelPolicy`, and router registry enrichment, so no model-level Fast toggle, `--fast` row, or proxy-generated `speed` field is produced. Native Claude Messages passthrough still forwards a `speed` field the caller sends itself, outside the proxy Fast policy. `tests/adapters/anthropic/anthropic-fast-opt-in.test.ts` pins the default, the switch, and the management PATCH/GET. For `api.anthropic.com` only, the Claude client's typed web tools (`parsed._anthropicServerTools`) follow the function tools unchanged, minus the caller's `cache_control`; a function tool of the same name wins, so the web-search sidecar's `web_search` keeps priority and `web_fetch` is still carried. No beta header is added: both tools are GA. Each streamed `web_search_tool_result` becomes a `web_search_call_begin`/`web_search_call_end` pair (the query of its `server_tool_use` in the same response, hit URLs and titles, or `failed` for an error result), which the Claude outbound renders back as the same block pair; a search Anthropic defers beside a client `tool_use` has no result in that response and surfaces nothing, and the replayed pair is dropped by the inbound translation, so a result without `encrypted_content` never reaches Anthropic. A streamed `web_fetch_tool_result` opens and closes the same cell with `fetch` set (the fetched URL and Anthropic's result content, verbatim); the bridge records it as an `open_page` `web_search_call` carrying `fetch_result`, and the Claude outbound renders it back as `server_tool_use` `web_fetch` + that `web_fetch_tool_result`, not counted in `web_search_requests`. Citations are not relayed. `tests/claude-integration/claude-translated-server-tools.test.ts` pins the wire, the sidecar priority, the bridge's client stream and JSON, and the direct encoder's stream. |

+The Codex-native ordinary Lite-history policy in `src/adapters/openai-responses/passthrough.ts` is off by default: it projects unreferenced remaining `web_search_call` cells through `src/adapters/openai-responses/compaction-search-history.ts` only when the selected provider has `projectResponsesLiteHostedSearchHistory === true`, after bridge restoration, query backfill and schema normalization. The optional setting is a strictly validated boolean; omission, `false`, and malformed runtime values never enable projection. Exact canonical ChatGPT `/responses` still requires explicit Responses Lite intent: final `x-openai-internal-codex-responses-lite` header `true`/`false` is authoritative, otherwise an exact `true` in a valid string-map `client_metadata.ws_request_header_x_openai_internal_codex_responses_lite` selects the existing WS metadata intent. This reads the final request without changing headers, metadata or transport behavior. Non-Lite or unrecognized effective intent keeps structural hosted history; models, subscription auth, missing hosted tools and `additional_tools` alone are not a gate. The policy remains independent of diagnostic controls; only a same-scope bridge memo proves a restorable call/result, never an id prefix, model name or cache miss. Same-input `item_reference.id` matches retain their hosted cell; `store:false` removes references earlier. Notes are untrusted metadata, not instructions/page content: action and top-level `sources` copy only url/title/type, strings cap at 2,048 UTF-16 units, lists at 20, projected notes at 65,536 bytes with an omission note. Tool declarations/Lite wrappers, choices, non-hosted order, call/results, reasoning and caller raw input keep their contracts. Native `/responses/compact` stays unchanged, including account scrubbing and opaque output; portable/routed summaries keep their existing triggers/default projection (now preserving allowlisted top-level sources), not the ordinary reference exemption. `tests/adapters/openai/openai-native-hosted-search-history.test.ts` and `tests/responses/responses-native-compact-search-history.test.ts` pin these boundaries. This is an explicit lossy policy, not issuer inference, retry, or a claim that Codex rejects valid hosted schema.

Invalid disk blocks disable retention with a warning without discarding unrelated config; candidate writes reject invalid fields and unknown keys. Runtime scope and recovery precedence follow [native reasoning retention](#runtime-boundary).
+
+`native-reasoning-retention-live-cli` owns the deferred dedicated live CLI verb for `PUT /api/native-reasoning-retention`. The dashboard and management API apply it live today; `ocx config set/unset nativeReasoningRetention` edits the same block on disk without live convergence, so restart after those local edits. The route registry records this follow-up rather than granting a mutating local-transport exemption.
+
+`src/server/management/native-reasoning-retention-routes.ts` owns `GET/PUT /api/native-reasoning-retention`. GET returns resolved `modelSwitch` and `accountSwitch` booleans. PUT accepts a strict partial boolean object, preserving omitted fields, or JSON `null` to remove the block and restore defaults. Invalid writes and failures before publication leave live state unchanged; a failure after publication keeps the committed state authoritative. `gui/src/components/NativeReasoningRetentionPanel.tsx` exposes the two opt-ins on the dashboard overview; it requires a valid read before saving and fences stale server responses. Runtime scope and rejection precedence follow [native reasoning retention](#runtime-boundary).
+
+## Runtime boundary
+
+`src/types/request.ts` declares trusted parsed policy fields; `src/responses/reasoning-replay-cache.ts` reports known durable identity deltas without widening cache keys. `src/adapters/openai-responses/passthrough.ts` applies reasoning and compaction stripping independently.
+
+`src/server/responses/request-prepare.ts` snapshots the resolved policy into trusted parsed state. `src/server/responses/core-replay.ts` applies it to the selected concrete route, including each fresh Combo candidate. Retention is eligible only on the canonical ChatGPT Responses forward destination, with an unchanged provider, adapter and durable endpoint. A known model change requires `modelSwitch`; a known credential change requires `accountSwitch`; simultaneous changes require both. It does not widen the serving identity used for reasoning caches or strict plaintext Combo eligibility. Unknown or expired serving provenance retains the existing destination-only behavior rather than inventing a compatibility match.
+
+Account retention is experimental forwarding permission, not evidence that the backend accepts or reuses another caller's reasoning. `src/server/responses/account-change-state.ts` continues removing account-bound continuation references and foreign reasoning item ids; uploaded-file refusal stays independent. Opaque-blob rejection recovery and its rejection memo override retention. When retention actually kept ciphertext across a change, `src/server/responses/passthrough-dispatch.ts` also inspects the zero-output stream prelude, so a refusal ChatGPT sends inside a 200 stream (a Codex WebSocket `error` frame or `response.failed`) takes the same single sanitized rebuild as an HTTP 4xx refusal. Previously stripped ciphertext is never restored in a later recovery leg. Claude-native per-blob replay tags remain authoritative: retention never permits a blob whose durable endpoint or generation-bearing credential fails its tag check.
+
+Only reasoning `encrypted_content` is covered. Native compaction cleanup has its own internal flag and preserves the existing identity-change behavior. Direct native `/v1/responses/compact` sanitization is unchanged. API-key providers, arbitrary forward aliases and translated destinations receive no new permission. The configuration and management surface is described above.

Only explicit `reasoningRetention.enabled: true` (default off, including legacy limit-only blocks) makes routed v1 `/responses/compact` and direct routed v2 `compaction_trigger` use `src/responses/reasoning-retention.ts` to withhold readable reasoning from its summarizer; exact text including its historical-context frame within the smaller configured percentage/token cap is restored as framed historical context only after a readable summary succeeds. Repeated compact removes that frame locally again; ordinary requests replay it as a user context message, not a fresh reasoning item. Overflow is provisionally archived once per routed turn and kept only when the returned readable summary names its path; failed, cancelled, invalid, or opaque outcomes remove that attempt's file without deleting earlier successful archives. The percentage/token cap bounds retained context only; each overflow file is request-admission bounded under the resolved OpenCodex home’s `reasoning-archive/`, with no aggregate quota or automatic expiry. Successful archives require manual deletion; switching off or resetting does not delete them. Crash or filesystem cleanup failure can leave provisional files. Failure yields no replacement history. Opaque compaction returns only its unchanged item (no added retained message or rewritten ciphertext); native compact keeps existing behavior. Direct routed v2 remains a single compaction output item: `src/responses/retained-compaction.ts` encodes summary and framed reasoning separately as versioned `ocx2:` JSON/Base64 (encoding, not encryption). Replay expands them into separate historical messages; repeated v1/v2 compaction withholds the reasoning again. Existing `ocx1:` summaries remain readable. `src/codex/ocx-compaction-history.ts` also lowers `ocx2:` into separate summary and reasoning messages for explicit native-history recovery, so later proxy compaction still withholds reasoning. `src/server/responses/compaction-retention.ts` owns provisional archives and request-budget retention; failure or body cancellation releases the attempt. Emergency recovery preserves the structured envelope for JSON and SSE instead of flattening reasoning into the summary. `tests/responses/reasoning-retention-v2.test.ts` and `tests/responses/responses-compaction-recovery.test.ts` cover v2 replay and recovery; `tests/responses/reasoning-retention-routing.test.ts` covers these public contracts; `tests/responses/reasoning-retention.test.ts` covers envelopes, limits and archive failures.

+Custom `openai-responses` gateways declare native v2 triggers with `supportsNativeCompactionTrigger` and native v1 endpoints with `supportsNativeCompactEndpoint`; neither flag implies blob replay or OpenAI identity. `src/adapters/openai-responses/transport.ts` shares normal URL/auth/header construction with custom native v1 key/local/forward routes; generic OAuth retains routed compaction so the existing credential selection, refresh and dispatch fence own authentication. Native v2 remains an independent declaration. Custom native v1 honors `preserveResponsesReasoningContent: true` in both sanitizer passes only for custom destinations; absent/false and OpenAI-operated compact destinations blank raw reasoning content. Proxy-owned `ocxr1:` envelopes are always stripped, and plaintext preservation grants neither native generation nor ciphertext replay. Both custom v1 sanitizer passes omit non-array reasoning content channels and reuse `requiresPlaintextReasoningReplay` from `src/adapters/openai-responses/passthrough.ts`: custom providers with plaintext preservation and strict tool-result adjacency strip opaque reasoning ciphertext and backfill missing `reasoning_text` from `summary_text` or the existing minimal placeholder, while preserving available plaintext. Each physical send applies `dropResponsesReasoningItems: true` and strips private input message metadata unless `preserveResponsesMessageMetadata: true`, using the ordinary adapter policy; OpenAI-operated compact metadata, reasoning items and null channels retain their established policy. Custom v1 scrubs compaction ciphertext, reasoning ciphertext and foreign reasoning ids after each serving bind, using ordinary turns' parent-thread-first replay scope; provenance commits require a successful HTTP response and a validated replacement history with replayable compact ciphertext or nonblank message text, absent/completed status and absent/null error (`nativeCompactResponseSchema` in `src/responses/schema.ts`). Invalid or empty bodies preserve the prior identity; validation never rewrites the relayed body or request-log metadata. Daybreak endpoint restrictions remain canonical-only. A native 404 handoff preserves User-Agent and allowlisted provider-opted-in metadata through `src/server/responses/core-auth.ts` without widening credential forwarding. Every custom native v1 send carries only the gateway transport's headers, and Codex pool recovery (401 refresh replay, quota and transient alternates) and pool outcome recording skip gateway sends, so recovery cannot put a stored ChatGPT credential on a gateway wire (`tests/responses/native-compaction-gateway-credentials.test.ts`). Readable reasoning retention also bypasses native v2-capable gateways; the capability predicate controls local retention as well as dispatch. V1 fallback remains portable even for v2-capable gateways; cross-provider overrides still force portable summaries. `tests/responses/native-compaction-gateway.test.ts`, `tests/responses/native-compaction-gateway-policy.test.ts` `tests/responses/native-compaction-provenance.test.ts` and `tests/responses/native-compaction-oauth.test.ts` pin these boundaries.

 ## Decoded checkpoint continuation

 The note is a prompt contract and grants no authority. Completed requests remain history unless a later user message asks to repeat them. Unfinished work continues only under existing authorization and within its scope, without asking for that authorization again while it still applies. Permission and confirmation gates remain authoritative: a pending decision or required permission must resolve before the dependent action. Checkpoints and delegations, including those from another thread, neither grant authority nor expand scope. Later user messages take priority, including pause, cancellation, replacement and scope changes.

Both shadow-intercept sites use `shadowCallPreservesSelectedModel` in `src/lib/shadow-call.ts`: explicit `request_kind: "turn"` plus `thread_source: "user"`, or spawned-child provenance, preserves the selected model. `x-openai-subagent: collab_spawn` is a connection header on both transports (a child session opens its own connection); turn metadata comes from the HTTP `x-codex-turn-metadata` header or, on WebSocket, only from each frame's `client_metadata["x-codex-turn-metadata"]` (including `subagent_kind: "thread_spawn"`), never from stale upgrade metadata. Kind-only `turn` helpers and missing/malformed metadata retain interception; concrete self-targets remain no-ops and helper combos retain failover. `tests/responses/responses-shadow-intercept.test.ts` covers both sites and frame precedence. xAI OAuth model-scope admission previews the billed Fast lane using the serialization decision shared with Chat, Messages and routed compact admission; final normalization rechecks the actual wire destination. |
 | `shadow-target-availability.ts` | Shadow-call target resolution for `request-prepare.ts`: an unavailable target fails once with `409 intercept_target_unavailable` instead of reaching the native source model or the default provider. |

Subject: [PATCH 61/72] refactor: break config-facade import cycles (189 -> 59
 static cyclic modules) (#6454)

Contributed by @lcxhh521; refreshed onto dev by the maintainer (dev merge, deferred quota account-row edge to keep the cycle baseline from growing).

Remote validation (hosted GitHub Actions unreliable; local tests not run by maintainer rule): union candidate codex/prr-integ-8 = dev c03eafd + #7224 + #7223 + #7225 + #7217 + #6454 + #6594 plus a Gentle Shell import-cycle fix (integ-9 e1f289c: typecheck + full suite on mini (Windows) and lidge (Linux), compared with the same host's dev runs) and a test-only Windows path-escaping fix for the reasoning-retention routing test (integ-10 0d4cba7, tree a2b309a: that file re-run on both hosts).

+/**
+ * Import-cycle ratchet for the proxy runtime (issue #6386, INV-LAYER-01).
+ *
+ * The runtime import graph once held one strongly connected component of 222 modules, so an edit
+ * in nearly any domain could reach nearly any other, and the three files INV-LAB-01 protects sat
+ * inside it. Breaking that component is incremental work. This scanner keeps the progress: the
+ * baseline lists every module that is still on a cycle, and the test beside it fails when a module
+ * outside that list joins one, or when a listed module leaves without the list shrinking with it.
+ *
+ * Edges are load-time value imports parsed by Bun: static imports, side-effect imports,
+ * and runtime re-exports. Resolution follows Bun's local module precedence.
+ * \`import type\` is erased and a dynamic \`import()\` is a deferred edge that only loads when its
+ * branch runs, which is the sanctioned way to break a cycle, so neither forms an edge here.
+ *
+ * Importing this module scans nothing. \`bun scripts/import-cycles.ts\` prints the current count and
+ * \`--update\` rewrites the baseline, which only ever removes members.

 Known Claude Sonnet and Opus 5.5 base and low/medium/high IDs share a deterministic usage identity in `src/providers/antigravity-models.ts`, independently of live discovery. This accounting map does not migrate saved routing selections; Claude 4.6 and unknown suffix identities remain unchanged. Antigravity model entitlement is per account: one account may list Claude 4.6, another only the Claude 5.5 suffix families, and Gemini 4 Argon only on Ultra/Enterprise. `ANTIGRAVITY_MODELS` is therefore a static superset (Gemini 3.8 Flash, Gemini 4 Argon, Claude Opus 5.5, Claude Sonnet 5.5), and `ANTIGRAVITY_KNOWN_PICKER_MODELS` keeps dropped bases known to routing, discovery collapse and usage identity. The catalog exposes only what the active account's authoritative discovery returns. `src/providers/antigravity-account-roster.ts` records each account's discovered roster (in memory, six-hour freshness, scoped to config home); `src/oauth/generic-account-failover.ts` ranks Antigravity accounts by it the way it ranks Kiro listings: a listing account wins, a known non-listing account is skipped while another remains, and an account without a fresh roster is unknown and stays usable. Gemini 4 Argon requests and Antigravity model discovery send the Antigravity CLI User-Agent; every other model keeps the IDE User-Agent.
 When the `retrieveUserQuotaSummary` endpoint has no usable result, `src/providers/quota/antigravity.ts` preserves bounded per-model `quotaInfo` measurements from `fetchAvailableModels` alongside the existing first-seen Gem/Cla family summaries. Model windows carry the exact CCA wire ID and distinct labels of at most 128 characters for display and diagnostics; GUI summaries and native compact rows preserve the discriminator, retain details, and exclude model readings from headline and severity selection; account and provider routing ignore these rows and continue to use family summaries, and `src/quota/window-mapping.ts` keeps them out of quota-reset observation so one pool reset notifies once. A missing model row or failed probe is unknown evidence, not a model eligibility verdict. Per-account cache entries are bound to the current credential and project identity. Paused reads retain only current last-good measurements without probing; `src/providers/quota/account-row.ts` preserves private currentness callbacks through account-row projection until management publication.
 
+Account-row projection is loaded with `import()` after each account probe in `src/providers/quota.ts`; its cache dependencies do not create a static return edge into the quota facade.

 ## Combo model refusal evidence
 
 `src/combos/failover.ts` recognizes a bounded, exact HTTP 400 plan/model refusal, not credential or entitlement evidence.

Only a `FAIL`-level condition records a doctor failure — a degraded-but-working install must not break a green pipeline. `collectDefaultModelExposure` compares Codex's root `model` pin against the exposed set, which it READS rather than recomputes: the running proxy's `/v1/models` through the byte-capped direct-local transport when one answers, otherwise the on-disk catalog's `visibility: "list"` slugs.

 | `src/codex/shim.ts` | Codex autostart facade: dispatches Unix private PATH overlays to `src/codex/shim-overlay.ts` and retains Windows in-place script wrapping. `src/codex/shim-migration.ts` owns explicit legacy Unix restoration. Legacy Unix shim migration rejects symlink, foreign-owned, and group/world-writable state files. The writable-mode refusal prints a shell-quoted `chmod 600` hint; it clears only that mode refusal, leaving file-type and ownership checks intact. `tests/codex-integration/codex-shim-migration.test.ts` executes the hint through `/bin/sh` with a space and apostrophe in the state path, then verifies mode `0600` and schema-2 migration. `src/codex/shim-diagnostics.ts` owns diagnosis/status, distinguishes runnable from active overlays and states the unhealthy verdict for a damaged in-place (Windows) wrapper. `src/codex/shim-templates.ts` uses `src/lib/self-launch-argv.ts` to invoke standalone executables with `ensure` directly in Unix, CMD and PowerShell wrappers, without a virtual source entrypoint; management subcommands bypass startup even after value-taking global flags. Discovery resolves fnm’s temporary `fnm_multishells` directory to the durable installation directory through `src/codex/shim-path-resolution.ts`, taking the directory realpath while retaining the command basename; unresolved temporary entries refuse installation. The injected path flavour governs join and separator. The shared PATH scanner follows npm/fnm symlinks and POSIX target execute access, skips non-executable and special-file entries, and reads only the first 16 KiB of regular files through a descriptor with nonblocking POSIX open and a post-open type check. An unreadable executable still shadows later commands. Overlay activation requires the selected executable to identify the recorded private wrapper or the same file through an alias; another marker-bearing shim does not prove activation. Shell functions/aliases and empty PATH components are outside this scanner’s guarantee. `src/cli/codex-shim-readiness.ts` retains connect’s advisory exit policy. `tests/codex-integration/codex-shim-path-readiness.test.ts` covers POSIX shell lookup parity, FIFO replacement, symlinks and bounded reads. Windows retains PATHEXT lookup without POSIX execute-access checks. |

On Windows, `src/service/windows-process-priority.ts` raises the process that binds the proxy to ABOVE_NORMAL just before `startServer` (best-effort; `OCX_DISABLE_PRIORITY_BOOST=1` opts out), because the NORMAL task priority (`<Priority>4</Priority>`) still let a saturated host hold `/healthz` past the 750 ms CLI liveness ceiling; spawned children fall back to NORMAL since Windows does not inherit ABOVE_NORMAL. The Task Scheduler batch wrapper (`src/service/windows-taskxml.ts`) checks bundled Bun against `REAL_BUN_MIN_BYTES` before each launch: npm's placeholder, or a file that vanished before its size was read, is logged and re-checked every five seconds instead of executed, while a Bun path missing at the exist check keeps the backup-restore then exit-3 path ([wrapper contract](ops/docs-and-release.md#windows-service-wrapper-and-incomplete-updates)). |

From: lcxhh <lcxhh521@gmail.com>
Date: Thu, 15 Oct 2026 23:31:07 -0700
Subject: [PATCH 62/72] refactor(oauth): break the ChatGPT OAuth and auth-api
 import cycles (59 -> 35) (#6594)

Contributed by @lcxhh521 (stacked on #6454); refreshed onto dev by the maintainer.

Remote validation (hosted GitHub Actions unreliable; local tests not run by maintainer rule): union candidate codex/prr-integ-8 = dev c03eafd + #7224 + #7223 + #7225 + #7217 + #6454 + #6594 plus a Gentle Shell import-cycle fix (integ-9 e1f289c: typecheck + full suite on mini (Windows) and lidge (Linux), compared with the same host's dev runs) and a test-only Windows path-escaping fix for the reasoning-retention routing test (integ-10 0d4cba7, tree a2b309a: that file re-run on both hosts).

From: JUN <jun@lidgeai.com>
Date: Fri, 16 Oct 2026 00:47:59 -0700
Subject: [PATCH 63/72] feat(cli): carry usage comparison, log history, restart
 and Codex controls (#7211, #7212, #6381, #7172, #6152) (#7222)

Carried from #7211, #7212 (both opened against main; carried onto dev), #6381, #7172, #6152 (one commit per source PR, original authors preserved). Custom provider routing consent defaults to No and the CLI update plan is read-only.

Remote validation (hosted test shards passed on the head; local tests not run by maintainer rule): exact head b4d6376 (contains dev 7a42860) typecheck + full suite on lidge (Linux) and mini (Windows), compared with the same host's dev 7a42860 runs. Security review of the #7172/#6152 carries: PASS.

 Les commandes de gestion communiquent avec l’API de gestion du proxy actif. Elles s’appuient sur le port d’exécution enregistré et sur des contrôles d’identité, plutôt que sur un second chemin de configuration. Un proxy arrêté ou inaccessible est représenté par une réponse HTTP 503 et entraîne un code de sortie CLI non nul. Les commandes explicitement documentées comme des opérations de configuration hors ligne peuvent, quant à elles, valider et modifier le fichier de configuration sans proxy actif.
 
-`ocx system codex-cli-update check` ne nécessite aucun proxy actif et n’interroge aucun registre de paquets. La commande inspecte, dans des limites strictes, les métadonnées de provenance du candidat d’installation configuré, notamment l’emplacement expurgé de l’exécutable et les preuves de propriété. Le contexte de confiance du lanceur publié authentifie uniquement cet instantané du candidat, et non l’exécution réussie de Codex. Comme cette commande ponctuelle n’exécute jamais Codex, les candidats issus de l’environnement ou de l’état persistant restent purement informatifs (`managed: false`, normalement `selection_unattested`) et `selectionAttested` reste `false`. La sortie JSON contient `candidateAvailable`, `candidateVersion`, `candidateSource` et `selectionAttested: false`. Une exécution directe via Bun ou depuis les sources ne fournit pas la preuve du lanceur, ignore les candidats issus de l’environnement ou de l’état persistant et peut signaler `candidate_unavailable` sous POSIX ou `windows_inspection_deferred` sous Windows. Sous Windows, cette première étape n’effectue aucune E/S de système de fichiers sur les chemins du candidat ou de configuration. Seul un candidat d’environnement absolu capturé par le lanceur de confiance peut recevoir une étiquette lexicale de bundle d’application ou de gestionnaire de versions ; tous les autres candidats Windows échouent de manière fermée. La commande n’installe ni ne répare de logiciel, n’exécute ni Codex ni npm, ne contrôle aucun processus actif et n’écrit aucun état de configuration ou de cache.
+`check` ne consulte aucun registre et n’exécute pas Codex. Sur POSIX, `selectionAttested` peut être `true` si le résolveur choisit le même chemin canonique que le candidat d’environnement capturé par le lanceur publié. Un manifeste npm-global lié peut alors établir `managed: true` s’il prouve la propriété et, lorsqu’une version candidate est signalée, si elle correspond à celle du manifeste ; les candidats persistants restent non attestés. Windows diffère l’inspection sans lire les fichiers du candidat ni la configuration. Une exécution directe via Bun ou les sources n’a pas de preuve du lanceur. `plan` consulte le registre officiel avec une configuration, un cache et des journaux npm temporaires isolés, et refuse les sessions actives ou une observation incomplète des processus. Il n’installe rien et n’envoie aucun signal. Voir [les commandes et motifs de refus complets (en anglais)](/reference/cli/agents/#read-only-codex-cli-update-plan).
 
 Pour observer une installation Windows x64, consultez [`attest`](/fr/reference/cli/agents/). Sans chemins explicites, la commande observe le candidat sélectionné identifié par l’instantané du lanceur lié à la preuve ; aucune autorité de mise à jour ni sélection du runtime n’est attestée.

Comme cette étape ne consulte jamais l’état persistant, une exécution Windows pour laquelle aucun candidat d’environnement n’a été capturé signale `windows_inspection_deferred` plutôt que `candidate_unavailable` : la commande ne peut pas observer si une CLI Codex est installée, elle signale donc le report de l’inspection au lieu d’affirmer qu’aucun candidat n’existe. La commande n’exécute ni Codex ni aucun gestionnaire de paquets, ne répare aucun shim, n’écrit ni dans la configuration ni dans le cache, n’arrête aucun processus et n’installe rien.

+`check` ne consulte aucun registre et n’exécute pas Codex. Sur POSIX, `selectionAttested` peut être `true` si le résolveur choisit le même chemin canonique que le candidat d’environnement capturé par le lanceur publié. Un manifeste npm-global lié peut alors établir `managed: true` s’il prouve la propriété et, lorsqu’une version candidate est signalée, si elle correspond à celle du manifeste ; les candidats persistants restent non attestés. Windows diffère l’inspection sans lire les fichiers du candidat ni la configuration. Une exécution directe via Bun ou les sources n’a pas de preuve du lanceur. `plan` consulte le registre officiel avec une configuration, un cache et des journaux npm temporaires isolés, et refuse les sessions actives ou une observation incomplète des processus. Il n’installe rien et n’envoie aucun signal. Voir [les commandes et motifs de refus complets (en anglais)](/reference/cli/agents/#read-only-codex-cli-update-plan).
 
 Sous Windows, une commande simple capturée comme `CODEX_CLI_PATH=codex`, un chemin distant ou un chemin de périphérique produit plutôt `candidate_path_unavailable`. Le candidat a été capturé, mais son chemin ne convient pas à cette inspection.

+## Opt in a custom provider to managed local routing
+
+A custom provider such as `chatgpt-http` may use `supports_websockets = false`
+to keep HTTP transport. OpenCodex leaves custom providers untouched by default.
+To delegate only that provider's URL to OpenCodex, run:
+
+```sh
+ocx codex-provider allow chatgpt-http
+ocx start
+```
+
+The first command explains the scope and asks for confirmation, defaulting to No.
+For an explicitly approved scripted operation, use `allow chatgpt-http --yes`.
+Consent applies to this provider ID in the selected `CODEX_HOME`; it does not
+approve other providers or other homes. Start and sync update only its `base_url`
+to the local proxy. Its identity, WebSocket setting, other TOML fields and history
+remain unchanged. Keep the proxy running while using this route.
+
+This mode supports explicit Responses provider tables with `requires_openai_auth = true`
+and no custom credentials or headers. Non-loopback targets, authless Desktop mode
+and client compaction require the existing dedicated integration instead.
+
+`ocx stop` and `ocx restore` restore recorded URLs while keeping consent for a later
+start. Run `ocx codex-provider status` to list approvals, or
+`ocx codex-provider revoke chatgpt-http` to restore its managed URL and remove consent.
+A URL changed outside OpenCodex is preserved and requires revoke followed by a new
+approval; OpenCodex does not silently adopt the replacement as a new baseline.
+The original URL assignment is retained in private recovery metadata under
+`OPENCODEX_HOME`, separately from the native config journal.
+
+Startup safety recognizes an approved provider's recorded managed URL as OpenCodex routing.
+This does not install restart protection: a manually started proxy still needs a viable
+background service to recover automatically after a restart.

+Run through the published Node launcher with the intended `CODEX_CLI_PATH` in the shell environment.
+The plan requires an attested POSIX npm-global installation and a linked package manifest version.
+It queries the official npm registry for an exact version, SHA-512 integrity and same-origin tarball,
+using the launcher's captured PATH and isolated temporary npm configuration, cache and logs. Proxy
+settings and `NODE_EXTRA_CA_CERTS` remain supported; cleanup is best-effort. No Codex command runs.
+
+An applicable plan reports `applicable: true` and a deterministic `planId` binding platform,
+installation-root digest, installed version, channel and target version/integrity. The plan is never
+persisted. It refuses downgrades, already-current versions, active Codex sessions and incomplete
+process observation. Windows returns `windows_inspection_deferred` before registry/process queries.
+A refusal exits 0: inspect `applicable` and `refusal`. The printed install argv is indicative; this
+command installs nothing, changes no application state and never signals a session. No apply command
+is exposed, and a plan ID is not installation authorization.

 ## Bounded display selections and per-key quota
 
+`src/cli/log-history.ts` pages `GET /api/request-history` and reads one canonical row by id. It is distinct from the recent `/api/logs` ring and from `ocx logs explain`. JSON is the management payload; JSONL emits entries and prints `nextCursor` on stderr when `hasMore` is true. Bounds reuse the usage timestamp parser. Invalid options fail before the request.
+
 `src/cli/log-view-filter.ts` owns the additive logs-filter snapshot, separate from existing follow/event transport. It fetches only the fixed log endpoint with a scan limit of at most 2000, applies GUI-equivalent local selectors, then returns the newest matches in source order without deduplicating. Model/provider matching covers resolved/served/attempt identities; protocol and conversation matching reuse their actual owners. Speed bounds accept observed value-kind metrics only. The versioned JSON view separates loaded, matched and returned counts from configured scan/output limits; JSONL is rows only. Neither a match count nor a cursor claims historical completeness or resumable search. Invalid options fail before discovery; malformed windows never become empty success.
 
+`src/cli/usage-compare.ts` reads `GET /api/usage` twice: the named range at now, then the same range shifted back one equal window. `--range all` is refused. Both responses must acknowledge the derived custom bounds. Key-scoped reads keep redirect-error transport and echoed `apiKeyId`. Connected clients reuse the existing hub usage path and refuse caller `--api-key-id`. Default range is 30d. The two reads are sequential, not an atomic snapshot.
+
 `src/cli/usage-model-search.ts` applies optional substring search only after the existing usage target/scope acknowledgment. A copied model list sorts stably by total tokens, searches model/provider/resolvedModel and caps at 100 by default. The report's other fields remain intact; explicit modelView metadata distinguishes a view miss from no usage. `src/cli/usage-report.ts` retains the legacy renderer when no view is supplied and renders the selected rows when one is supplied. `--top` accepts 1–1000 human model rows (default 10 without search, 100 with search), applies after search and is never sent to the API. JSON ignores `--top`, including the existing 100-row search view and its metadata. Search never becomes a server attribution query or widens connected-client/key scope.
 
 `src/cli/companion-usage.ts` reads settings and two usage ranges sequentially on a pinned management target through `src/cli/observe-stream.ts`. Its safe projection follows the saved model/provider filters and measured-totals rules in `gui/src/pages/tray-data.ts` without importing GUI runtime code. It retains unknown/incomplete metrics, valid server defaults with null update time, and explicit corrupt/fallback flags. Malformed settings stop before usage reads. Range failure retains the other observed range, labels unavailable data, and returns partial/nonzero; signal cancellation emits no late report. The observation owner supplies a separate 10-second fetch/body deadline after discovery and 32 MiB cap for each fixed GET, not a command-wide budget. Snapshot context supplies truthful retry wording without altering default follow behavior.
 
 `src/cli/account-api.ts` forwards explicit quota/refresh intent to the existing per-key owner; ordinary key listing omits both. Opt-in requests reject redirects. `src/cli/account-key-quota.ts` rebuilds the public ProviderQuota projection, including custom windows and credits, with finite-field validation and no credential or private publication fields. Missing mode evidence is unverified/nonzero. Human rendering separates probe/passive/unsupported, unavailable and unmeasured from actual zero; Codex/OAuth rendering remains separate. This read can invoke upstream quota work but does not change key selection or provider aggregate caches. Account list/current rows additionally project, through `src/cli/account-next-actions.ts`, only an allow-listed server health label, a locally generated recovery command built from shell-safe selectors (never server summary/action text), and the Codex boolean `creditsAfterLimit` as read-only consent readback; empty listings add a fixed next-action note to human output and JSON `notes`.

 Remote Link enrollment is shared with the dashboard through `src/server/management/link-enrollment.ts` and `src/cli/link-enrollment.ts`. `ocx link probe <alias>` returns a temporary SSH fingerprint/key type/version offer. `ocx link add <alias> --expect-fingerprint SHA256:…` confirms exact trust and applies under loopback admin authority, with TTY explicit confirmation when the flag is omitted. Non-TTY omission fails before discovery. One Home URL and a 360-second deadline cover all requests and bodies; redirects are refused, credentials are never printed, and post-connect residual failures retain fixed recovery. `tests/cli/cli-link-enrollment.test.ts` verifies these boundaries. Child `link status` fallback uses the shared projector with persisted client connection and `clientLinkTunnelStatus`, plus validated client-owned sidecar/marker initiation identity; ambiguous evidence never invents direction. An unobserved Home-owned tunnel is conservatively idle. Link-mode `status` reads supported Hub projections via the local Child without sending a credential; a standalone Home role-based 404 explains absent Hub state rather than recommending an upgrade.
 
 `ocx account preserve-signed-in openai` reads or updates the runtime-owned [signed-in quota policy](providers/openai-accounts.md#preserve-signed-in-quota), with affected entries, next choice and explicit next-request binding release. It never reads a local account roster.

+An explicit `sync --restart-codex` (or app-server-only scope) also reloads after a committed configuration-byte change, even when no catalog/cache was written. Without an explicit restart scope, configuration-only changes do not restart clients. Existing catalog/cache-write restart behavior remains unchanged; success alone is not proof of changed configuration.

+# Codex CLI Update Plan
+
+`src/codex/cli-update-plan.ts` constructs the read-only update plan;
+`src/codex/app-server-processes.ts` supplies its process observation.
+Installation inspection follows the [runtime inspection contract](runtime.md#lifecycle),

+
+Explicit Codex CLI installation observation does not discover a Codex home or read/write its state. See the [read-only observation contract](runtime.md#explicit-codex-cli-installation-observation).
+
+The read-only CLI update plan binds npm executable selection to the inspected launcher PATH.
+Registry integrity requires a canonical base64 SHA-512 digest of exactly 64 bytes; malformed or truncated tokens refuse the target.
+Selection observation uses the runtime resolver with provenance's bounded no-follow, nonblocking state reader and local executable-path policy. Windows returns before invoking the resolver; its deferred inspection performs no candidate or configuration I/O.
+Its child environment drops npm configuration overrides, named Node startup/output controls,
+and the `LD_*`/`DYLD_*` loader families; proxy settings and `NODE_EXTRA_CA_CERTS` remain supported.
+Distinct npm config files, cache and logs stay under the owned temporary root with best-effort
+cleanup; a cleanup error does not replace the computed plan/refusal. The POSIX update
+scan includes all readable users by default, retaining an explicitly injected UID scope.
+Linux per-process `status`/`cmdline` read failures invalidate a complete observation except for `ENOENT`
+(a process that disappeared); incomplete observation refuses with `blocked_process_state_unknown`;
+the restart/kill path skips unreadable entries while retaining independently verified same-user app-server targets. This plan neither installs a runtime nor signals
+an existing Codex session. Windows enumeration/installation limits remain unchanged.

 different home than the operator named would write provider state where nobody is looking for it. A proven missing home (including explicit `CODEX_HOME`) resolves lexically; native restore, remove and journal reconcile succeed without creating a directory or acquiring the config write lock. Dangling links do not prove absence, and existing homes retain ownership checks. Lock-path resolution never creates parents; unresolved parents yield a typed, handled refusal. Scalar and multi-agent feature edits refuse missing homes; prompt commits and native feature commands retain their directory creation before locking. The management native feature toggle resolves and retains the spawn invocation before preparing a home; unavailable executables return the toggle failure without creating it. Failed native toggles and prompt commits keep a home they created (`src/codex/prepared-home.ts`): a pathname-based removal cannot prove it still names that directory, and an empty home is what Codex itself creates. A fresh install can have that directory but no `config.toml` yet; applying the integration then creates an empty `config.toml` there (never overwriting an existing file) and continues, while a missing home directory is refused with instructions to start Codex once or set `CODEX_HOME` (issue 5422).
 On macOS, `src/codex/runtime.ts` tries the system then user ChatGPT.app bundle after environment, persisted selection, shim, PATH, established installs and a runnable bare fallback, preferring `Contents/Resources/codex-cli/bin/codex` over `Contents/Resources/codex`. Bundle membership compares the normalized and canonical (symlink-resolved) forms of the path and bundle with a segment boundary, including backing executables; candidate ordering keys on the generated app commands, so an established install path that links into the app keeps its precedence. Discovery and probe prechecks require exactly one top-level `CFBundleIdentifier` equal to `com.openai.codex` in a regular XML `Contents/Info.plist`, read in-process with a 64 KiB limit; the whole document must be valid plist XML, so binary, malformed (anywhere, not only in the identity pair), oversized or unavailable metadata fails closed. App candidates never supersede a runnable persisted selection, including legacy/discovered records and the fast path, but full discovery can report them in `newerAvailable`; invalid selections retain `replacedConfigured` recovery. When a verified app candidate exists, deferred discovery skips the bare fallback as a candidate and retains it only as the no-candidate sentinel.
 `src/codex/home.ts` imports path expansion directly from `src/config/paths.ts`, so a fresh WSL process can resolve its Codex home without re-entering the config facade before the resolver initializes.

+# Custom Codex provider routing consent
+
+`src/codex/provider-routing.ts` stores explicit, home-bound provider-ID approvals in
+private OpenCodex-home recovery records. Default external-provider preservation remains
+unchanged. The approved path manages only the provider table's URL assignment, preserving
+provider identity, HTTP/WebSocket settings and history. It uses the shared config write
+lock and destination guards; recovery evidence precedes URL publication and retains the
+previous and candidate local URL across an interrupted write. Changed foreign URLs refuse
+injection and survive restore. Native restore completes its existing preflight before
+restoring approved URLs. Foreground signal/exit cleanup delegates to the same native restore, which restores approved URLs and preserves unapproved external configurations. Partial native outcomes remain partial, and recovery failures are reported in the config artifact. Consent survives stop/restore; explicit revocation removes it. Successful URL publication returns a committed configuration-change receipt through injection/sync; validation-only and unchanged URL operations report no change, so explicit config-change restarts retain the same authority.
+Only Responses/OpenAI-auth provider tables without separate credentials or headers are
+eligible, and only ordinary loopback routing is admitted. Authless, client-compaction and
+admission-token targets are refused rather than silently changing authentication policy.
+
+`src/cli/codex-provider.ts` owns the default-No allow prompt, explicit `--yes` acknowledgment, status and revoke commands.
+
+Startup routing observation credits a custom provider as OpenCodex-local only when its
+actual loopback URL matches a URL recorded as published for that approved provider.
+Consent alone, an unapproved provider, or an independently changed local URL does not
+establish ownership. Existing service/shim availability still determines restart safety.

Subject: [PATCH 64/72] fix(gui): restore keep-native-v1 qualifier placement
 (#7237)

Restore the keep-native row that #7220 removed, while keeping its uniform settings rows and the auto-review override. Standard rows span the grid. Only the v2 qualifier sits in the right column, with a single-column fallback below 1160px. The four keep-native-v1 GUI tests that fail on dev 4ed45e9516 pass on this head.

Subject: [PATCH 65/72] fix(providers): charge API-key cooldown to the
 credential sent (#7240)

API-key cooldown from a 401/429 is now charged only to the distributed key that was actually sent. Ownership is captured at the physical fetch on native Responses, compact, Chat and Messages. Requests whose credential was changed after selection no longer cool down a pooled key. Configured same-key 429 retries are unchanged.

Subject: [PATCH 66/72] test: fix Windows default-home isolation fixtures
 (#7242)

On Windows, homedir() follows USERPROFILE. The owner-registry and service-state isolation fixtures changed that variable to a worker home while still expecting the registry and mirror seeded in the startup home. The fixtures now keep the default home stable while switching OPENCODEX_HOME, and every existing assertion is retained. Product behavior is unchanged.

Subject: [PATCH 67/72] fix(config): preserve legacy OpenCode Go configs after
 native wire pins (#7238)

#7216 added native wire pins for OpenCode Go Gemini and Qwen models. An existing config with a formerly valid override, such as modelAdapters["qwen3.7-plus"] = "openai-chat", then failed validation, and the whole saved config fell back to defaults. Both the runtime load path and diagnostics now normalize these overrides before validation, so the native pin wins and providers, accounts and routing survive. Strict validation still applies to new writes and malformed values.

Subject: [PATCH 68/72] fix(ci): preserve import cycles through macOS path
 aliases (#7241)

The import-cycle scanner now canonicalizes its root before scanning. Bun resolves import targets to physical paths, so on macOS (/var -> /private/var) and under any symlinked root, cycle edges pointed at missing nodes and directory-index cycles went unreported. Adds symlinked-root coverage for ts, tsx and mts directory indexes.

Subject: [PATCH 69/72] fix(compact): preserve retained reasoning across native
 combo failover (#7239)

When a translated combo compaction fails over to a canonical native target, the readable reasoning withheld before compaction is now returned after the native compaction item, or as an archive notice whose file survives a successful replacement. Previously it was dropped and its archive deleted. Cleanup on failure and cancellation is unchanged.

 The portable Responses summarizer in `src/adapters/openai-responses/passthrough.ts` uses `src/adapters/openai-responses/compaction-search-history.ts` to render remaining top-level `web_search_call` items, after bridge restoration, as assistant reference notes labeled untrusted historical metadata (not instructions or fetched page content). The allowlist keeps string status and action fields (type, query/queries, URL, pattern, source URL/title/type); opaque state, IDs, unknown fields and malformed values are omitted. Strings are cut at 2048 code units, lists at 20 entries, and one request carries at most 64 KiB of notes; later hosted cells collapse into a single omission note reserved inside that budget. Tool declarations stay absent, bridge-restored call/result pairs and existing messages/citations stay intact, and this portable path changes only compact summary input, never stored history or native compaction. Ordinary Codex continuation policy is separate: see [hosted-search-continuation](../providers-and-adapters.md#hosted-search-continuation-binding). A failed summary publishes no replacement history. Lite requests retain `parallel_tool_calls=false`, which the upstream requires even without tool declarations.

-validation, native and routed handlers, credential retention, portable summaries and replay, and combo failover. Only explicit `reasoningRetention.enabled: true` (default off, including legacy limit-only blocks) makes routed v1 `/responses/compact` and direct routed v2 `compaction_trigger` use `src/responses/reasoning-retention.ts` to withhold readable reasoning from its summarizer; exact text including its historical-context frame within the smaller configured percentage/token cap is restored as framed historical context only after a readable summary succeeds. Repeated compact removes that frame locally again; ordinary requests replay it as a user context message, not a fresh reasoning item. Overflow is provisionally archived once per routed turn and kept only when the returned readable summary names its path; failed, cancelled, invalid, or opaque outcomes remove that attempt's file without deleting earlier successful archives. The percentage/token cap bounds retained context only; each overflow file is request-admission bounded under the resolved OpenCodex home’s `reasoning-archive/`, with no aggregate quota or automatic expiry. Successful archives require manual deletion; switching off or resetting does not delete them. Crash or filesystem cleanup failure can leave provisional files. Failure yields no replacement history. Opaque compaction returns only its unchanged item (no added retained message or rewritten ciphertext); native compact keeps existing behavior. Direct routed v2 remains a single compaction output item: `src/responses/retained-compaction.ts` encodes summary and framed reasoning separately as versioned `ocx2:` JSON/Base64 (encoding, not encryption). Replay expands them into separate historical messages; repeated v1/v2 compaction withholds the reasoning again. Existing `ocx1:` summaries remain readable. `src/codex/ocx-compaction-history.ts` also lowers `ocx2:` into separate summary and reasoning messages for explicit native-history recovery, so later proxy compaction still withholds reasoning. `src/server/responses/compaction-retention.ts` owns provisional archives and request-budget retention; failure or body cancellation releases the attempt.

Subject: [PATCH 70/72] fix(claude): activate Windows picker after dormant
 startup (#7243)

A Windows Claude Desktop picker that started with intent off previously returned 503 picker_proxy_unavailable on a later enable. The controller now stays dormant and binds the picker relay under its enable lock after the mode, integration and preference checks. Startup stays relay-, timer- and credential-free while intent is off. Concurrent enables share one relay, and shutdown closes it.

 Claude Desktop first-party routes its Code tab and subagents through OpenCodex. The standalone Claude Code CLI has a separate first-party switch. Both clients read the same `~/.claude/settings.json` proxy and CA settings: if only one switch is on, the other client still transits the local proxy, where TLS terminates, but its Messages requests relay to Anthropic unchanged. Other Anthropic paths relay unchanged and unrelated hosts remain blind tunnels. With the CLI switch on, the standalone `claude` also lists routed models in `/model`; see [Model picker in the CLI](#model-picker-in-the-cli).
 
 :::note[Windows system proxy (Clash, v2rayN, corporate proxies)]
+When picker intent is off at OpenCodex startup, its Windows relay stays unbound. Turning picker
+mode on later starts it within the running service; OpenCodex does not need a restart.
 For picker-off installs or pending installs with no applied picker profile, a Windows system proxy
 is handed to the Code tab as `HTTPS_PROXY`, and
 that value takes precedence over the OpenCodex proxy in `~/.claude/settings.json`. The Code tab

Subject: [PATCH 71/72] fix(desktop): use Waker::noop for the Rust 1.99 clippy
 lint (#7246)

Rust 1.99 clippy (-D warnings) rejects the hand-written no-op waker in the desktop process_spawn test, which failed the desktop shell job on main and dev. The test now uses std::task::Waker::noop(), stable since Rust 1.85, under the crate's Rust 1.88 minimum.

Subject: [PATCH 72/72] fix(cli): preserve Codex opt-out and usage comparison
 ownership (#7244)

Approved custom Codex provider injection now rechecks the persisted integration intent under the Codex/config locks, so it can no longer undo integration OFF. Approval-record inspection, stale native-journal cleanup and URL publication share one write section, which fixes an unlocked read that #7222 added. The shared Codex config write lock now records the destination inode after acquiring the lock. Before, a writer that replaced the file just ahead of acquisition left a stale witness, and concurrent syncs failed. ocx usage compare binds both windows to one connection, usage owner, destination and credential fingerprint, and aborts with a retry message when they differ.

Connected clients reuse the existing hub usage path and refuse caller `--api-key-id`. Default range is 30d.

 `src/cli/usage-model-search.ts` applies optional substring search only after the existing usage target/scope acknowledgment. A copied model list sorts stably by total tokens, searches model/provider/resolvedModel and caps at 100 by default. The report's other fields remain intact; explicit modelView metadata distinguishes a view miss from no usage. `src/cli/usage-report.ts` retains the legacy renderer when no view is supplied and renders the selected rows when one is supplied. `--top` accepts 1–1000 human model rows (default 10 without search, 100 with search), applies after search and is never sent to the API. JSON ignores `--top`, including the existing 100-row search view and its metadata. Search never becomes a server attribution query or widens connected-client/key scope.

 previous and candidate local URL across an interrupted write. Changed foreign URLs refuse
 injection and survive restore. Native restore completes its existing preflight before
 restoring approved URLs. Foreground signal/exit cleanup delegates to the same native restore, which restores approved URLs and preserves unapproved external configurations. Partial native outcomes remain partial, and recovery failures are reported in the config artifact. Consent survives stop/restore; explicit revocation removes it. Successful URL publication returns a committed configuration-change receipt through injection/sync; validation-only and unchanged URL operations report no change, so explicit config-change restarts retain the same authority.
+Approval-record inspection, stale native-journal cleanup and URL publication share one Codex write section, so a cooperating concurrent sync cannot replace the record during its bounded read. The shared lock witnesses the config inode after acquisition, so a preceding writer’s completed publication does not invalidate the next holder. URL injection rechecks the current integration intent under both the Codex write lock and config mutation lock, after the client-write guard. Integration OFF skips URL and recovery-record publication without revoking provider consent. Validation-only inspection does not acquire the config mutation lock or create its persistent coordination metadata.
 Only Responses/OpenAI-auth provider tables without separate credentials or headers are
 eligible, and only ordinary loopback routing is admitted. Authless, client-compaction and
 admission-token targets are refused rather than silently changing authentication policy.
