feat(codex): window-aware main-account hard-lock thresholds and outside-usage warning - #6363
Merged
Merged
Conversation
…de-usage warning The main-account hard lock now compares each governing window with its own threshold: the 5-hour window locks at 90% and the weekly/monthly window at 98% by default, both configurable through codexMainAccountHardLockThresholds (integers 80..100, short <= long, malformed values fall back to defaults). Evidence retention keeps any reading at or above 80% so a lower configured threshold cannot be silently unlocked by an elapsed reset or partial update. A process-local detector compares fresh main-account quota observations and flags a rise inside the same reset episode while opencodex has not used the main account, so the dashboard and ocx status --json can warn that usage is being consumed outside opencodex. The human ocx status line reuses the OAuth health read instead of fetching the accounts endpoint a second time. Refs #6196, #4878

Merge Risk: 🔵 Low · up to Some outside-usage warnings can be missed after cooldown refusals or an account identity change. The hard lock remains in place, but users should not rely on this advisory as a complete signal; the merge risk is bounded. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The lower default short-window threshold provides more headroom, while configuration changes retain existing access controls. Two activity-accounting gaps can hide outside-usage warnings after account changes or refused requests. Neither gap bypasses the hard lock. Retained concerns

…status in admission tests structure/config.md, runtime.md and dashboard-and-usage.md fold the new notes into existing paragraphs so each stays at the 600-line budget; the threshold contract stays in providers/openai-accounts.md. The native-main admission test now asserts the complete status with thresholds and the blocking window.

A confirmed A-to-B switch calls
purgeMainCodexAccountRuntimeState()andforgetMainAccountUsage(). That function clearsbaselinebut leaves the module-globallastActivityunchanged. If B receives a baseline reading and then a same-reset increase within 30 minutes of A's activity, the quiet-period check suppresses B's warning even though B had no recent activity. This leaks A's activity into B's identity-scoped detector state.Suggested fix

Both hard-lock surfaces now pass the management payload's thresholds through hardLockThresholds, which falls back to the server defaults unless both values are finite percentages. Adds focused tests for projectMainAccountPolicyHealth's rejection branches and external-usage whitelisting.
A hard-lock refusal used to note main-account activity before the policy check, so repeated refused requests suppressed the outside-usage warning exactly while the lock held. Activity is now noted after the request is admitted. The settings route also rejects an empty codexMainAccountHardLockThresholds object instead of storing {}. Both found by the independent security review of a747130.

On macOS tmpdir() is under /var, a symlink to /private/var. The no-follow writer resolves the registry's parent, so the icacls stub saw /private/var paths, failed its root-prefix assertion inside the swallowed registration and left the registry empty. #6375's CI never ran the macOS shards; this PR does, and macos 1/2 failed at owner-registry-acl.test.ts:72. Test-only fix.

lastActivityis global, butbaselineis identity-scoped. After the A→B transition, activity from A can remain within the quiet window when B records its baseline. A same-reset increase of at least one point for B can then suppress the warning, even when B has no recent activity.
purgeMainCodexAccountRuntimeState()already clears the main usage baseline throughforgetMainAccountUsage(). ClearlastActivitythere as well. Do not address this only by excluding cooldown refusals from activity recording; that does not remove activity recorded for A.Suggested fix

Summary
The main-account hard lock (default on since #5694) stops opencodex from sending new main-account requests at 98% on either the 5-hour or the weekly window. That keeps opencodex-driven usage from reaching the 100% reading at which the Codex desktop app disables Send (#6196, #4878), but two gaps remain: a long turn on a small Plus 5-hour window can cross 98% before the next observation, and usage outside opencodex (ChatGPT web or mobile, Codex cloud, another machine) can exhaust the account where the lock cannot see it.
This PR narrows both gaps without changing the lock's shape:
codexMainAccountHardLockThresholds: { short, long }(integers 80–100,short ≤ long).PUT /api/settingsvalidates the object before writing, accepts a partial update, and restores it on rollback. A malformed value on disk falls back to the defaults.src/codex/quota.tsnow keep any reading at or above 80%, so a configured threshold below 98 cannot be silently unlocked by an elapsed reset or a partial WHAM update. Retaining a reading below the active threshold only keeps the percentage visible; it never blocks.src/codex/main-account-external-usage.ts, no persistence and no timers) compares fresh main-account observations. If usage rises inside the same reset episode while opencodex has not used the main account, the dashboard shows "Possible usage outside opencodex. The lock may not prevent exhaustion.", andocx statusprints the same note. The warning expires after 6 hours or at the window reset, and an identity change clears it.ocx statusprotection line show the effective thresholds instead of a fixed 98% in all ten locales.ocx status --jsongains a whitelistedmainAccountHardLockprojection. The human report reuses the existing OAuth health read, so it does not query the accounts endpoint twice.Default behaviour change to note in the release: an account whose 5-hour window reaches 90% is now held off the main account (other pool accounts and providers stay available). Set
codexMainAccountHardLockThresholds.shortto 98 to restore the previous behaviour.This is the first item of the split roadmap in
devlog/_plan/261001_quota_send_lock_split/(included here). The app-server shim, the local-CA intercept, and the PAC fallback from #5947 are separate PRs and are not part of this change.Refs #6196, #4878
