Summary

Lane E of the simplification program: the Rust core runtime, settings and CLI in rust/src (providers, locale, usage_snapshot, wayfinder and the lane F cost/JSONL files excluded). The change is behavior-preserving. Persisted settings formats, serde names, aliases and defaults, CLI flags and output text, bridge DTOs, and settings tab ids are unchanged. Before risky levers, new pin tests were added first: hooks help text, the dashboard icon table, hook timestamps, forecast series, the token account table, and settings parse-error strings.

Deleted (one module per commit)

  • RCO-01 orphan modules: shortcuts.rs, status/indicators.rs, core/credentials.rs, core/widget_snapshot.rs (RCO-09) and core/session_quota.rs (RCO-10). I checked the port ledger first. None of them has a caller outside its own file and re-export.
  • settings/status.rs, the legacy settings setters and accent-color helpers, and the test-only per-provider setters.
  • RCO-02/03 hard-dead and test-only items:
    • in core: redactor redact_email, provider_state::is_problem, http_proxy validation_error, and the codex_accounts model helpers
    • in updater: the pending-installer scan and the never-read prerelease field
    • in wsl: windows_path_to_wsl
    • in tray: the BadgeType remnants
    • both RollingBuffer copies (tty_runner and host)
  • RCO-07: the never-read requires_api_key / config_file_path fields on ProviderConfigInfo.
  • RCO-08: the test-only Codex host-cost renderer copy in cli/cost.rs. The live renderer is codex_costs/host_costs.rs.
  • RCO-13: the unused forecast copy of persist_recorded_windows, and the never-constructed AccountKeyMismatch burndown error.

Unified

  • RCO-11: TokenAccountSupport::for_provider builds its rows from cookie and API-key constructors.
  • RCO-12: hook timestamps format with chrono. The output is byte-identical: Z suffix, no fraction, pre-epoch clamp kept.
  • RCO-13: the forecast session and weekly series are driven from one table.
  • RCO-26: the dashboard icon table is generated by a macro and pinned against the icons dir.
  • RCO-27: CLI pass-throughs are dropped and test-only helpers are gated.
  • RCO-28: tty_runner shares the DSR and elapsed helpers.
  • RCO-30: CLI FetchContext literals use ..FetchContext::default().
  • RCO-31: one print_json helper serves all CLI commands.
  • RCO-32: repeated patterns in cost, account, usage, serve and guard are deduped. Hooks share one set of JSON output args and one test-result push.
  • TST-03 (settings tests):
    • The language, theme and clamp tests are table-driven. Every former input and expected value is a row.
    • test_settings_load_missing_language_field_defaults_to_english now actually omits ui_language.
  • The module-level #![allow(dead_code)] lines are removed from browser, cli, openai_dashboard, host/command_runner, login, notifications, settings, sound and status, and so is the item allow in tray/icon and updater. Fixed what that surfaced:
    • ensure_aumid_registered is cfg'd out of tests.
    • MINIMUM_WAV_SIZE moved into the sound tests.

Split (every file named in the brief is now under 800 lines)

  • settings.rs 1387 -> 750 lines. It is split into settings/persistence.rs (load, save and migrations), settings/start_at_login.rs and settings/provider_accessors.rs.
  • settings/tests.rs -> 701 lines. Split out: settings/tests/language_theme.rs, settings/tests/provider_configs.rs and settings/start_at_login/tests.rs.
  • cli/serve/tests.rs -> 234 lines. Split out: tests/head_bound.rs and tests/dashboard_routes.rs.
  • core/session_equivalent_forecast.rs -> 516 lines. The history store moved to session_equivalent_forecast/history.rs.
  • cli/tty_runner.rs -> 680 lines; the options moved to tty_runner/options.rs.
  • managed_process.rs -> 768 lines; the command-line encoding moved to managed_process/command_line.rs.
  • Inline mod tests blocks of 10 large files moved to sibling <stem>/tests.rs. Test paths are unchanged.

Splits are line-range extractions, not git mv. To review them as moves, use git show --color-moved=dimmed-zebra and git blame -C -C.

Skipped

  • RCO-05 (RawSettings legacy-only shim), skipped by its own gate.
    • A flattened legacy struct moves the serde error position for a bad legacy field. For example, "codex_cookie_source": 5 reports "line 2 column 26" today and would report "line 3 column 1" with the shim. settings_parse_errors_are_pinned now pins those strings.
    • Hiding the legacy fields would also force them to be pub, because 107 ..Settings::default() literals sit outside the module, including the desktop crate.
  • RCO-12 spawn reuse, not done. emit_quota_threshold_hooks runs one thread for several events and ignores spawn errors with .ok(). spawn_hook_dispatch spawns one thread per event and uses .expect, so reusing it would change behavior.
  • Not in lane E: RCO-04/04b (lane D, or a tooling decision), RCO-06 (call sites in providers and shell), RCO-29 (a feature decision), and RCO-14..25 (lane F).

LOC (loc.py, origin/main 522699d -> HEAD)

All of the change is in the lane E area of rust/src.

Test inventory (cargo test -- --list)

crate before after
codexbar 3752 (at 3226d2f) 3722 before rebase; 3733 after rebase (diff of the two: only the 11 new providers::kilo::* tests from main)
codexbar-desktop-tauri 639 639 (identical names)
  • In codexbar, 95 names are gone and 65 are added. Every gone name is justified case by case in the lane ledger (inv-E-removed.md): a test of deleted dead code, a table-row merge, or a path rename from a split.
  • The added names are the moved paths plus 8 new pins.

Commands run (after rebase on origin/main 522699d)

  • cargo fmt --all: clean.
  • cargo clippy --workspace --all-targets -- -D warnings covers both crates (the root workspace holds both manifests): clean.
  • cargo test -p codexbar: 3731 passed, 0 failed, 1 ignored, plus 1 and 0 in the other targets. The count includes 11 kilo tests that came in with main; before the rebase it was 3720.
  • cargo test -p codexbar-desktop-tauri: 639 passed, 0 failed.
  • grep -rn "rust/src" apps/desktop-tauri/src: the frontend tests read only core/provider.rs and locale/*, and both are untouched.
  • scripts/local-check.ps1 -Slice ci was not run: the workstation's no-permanent-delete hook blocks its cleanup step. Its Rust slice was run piece by piece as listed above.
  • Builds used a C: target dir for this process only, because W: is full.

Behavior-risk notes

  • No UI-visible change: the tray and settings edits are dead-code removal and file splits only, so CUA proof does not apply.
  • Hook timestamps for years above 9999 would now get chrono's sign prefix. This is unreachable: every caller passes the wall clock.
  • updater no longer deserializes prerelease. serde ignores the unknown key.
  • The one edit outside lane E is in rust/src/codex_costs.rs (lane F): it drops the now-unused CodexHostCostWindow re-export.

Cross-lane follow-ups

  • Lane F could port the unknown-dash assertions of the deleted cli::cost host-text test to host_costs.
  • Lane F: there are dead items in the jsonl and cost_scanner files.
  • Lane C: launch_block_reason is used only by src-tauri tests.
  • usage_snapshot most_restrictive / any_exhausted belong to the Serialize Wayfinder snapshot as camelCase for the bridge #791 owner.
  • locale tray_tooltip belongs to lane D.
  • Lane E files still over 800 lines that the brief did not name:
    • cli/serve/mod.rs 810
    • core/quota_burndown.rs 816
    • coordinator/tests.rs 877
    • core/models_dev_pricing.rs 897
    • core/hooks.rs 903
    • browser/cookies.rs 930
    • agent_sessions.rs 936
    • agent_sessions/pi_family_tests.rs 850

Validation fix round

An adversarial validator reviewed 1541dc9 and returned SHIP. This round fixes its low-severity findings in five commits, with no change in behavior:

F1, porting the host-cost assertions, is not part of this round.

Checks at b28869b:

  • cargo fmt --all --check: clean.
  • cargo clippy --workspace --all-targets -- -D warnings: clean.
  • cargo test -p codexbar: 3731 passed and 1 ignored, plus 1 bin test.
  • cargo test -p codexbar-desktop-tauri: 639 passed.

Merged main (603681a, #793)

Merged origin/main with a normal merge commit (no rebase). Main had already advanced to b84e797 (#791, Wayfinder camelCase snapshot) when fetched, so that is included too. Conflicts: settings.rs took the branch side (the accessor block lives in settings/provider_accessors.rs), and main's Groq "auto" cookie-source default plus doc comment went into provider_accessors.rs::cookie_source. settings/api_keys.rs took main's new Groq help text, minus the config_file_path field the branch removed. Main's two Groq tests auto-merged into settings/tests.rs next to their neighbours. Checks: fmt, workspace clippy -D warnings, cargo test -p codexbar 3770 passed / 1 ignored, cargo test -p codexbar-desktop-tauri 641 passed.

Priority: ⬇️ Low

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to 4cf9d

This refactor reorganizes Rust settings, CLI, and core modules. No user-facing regression has been shown. The open items are weak tests: some can pass without detecting the behavior they guard, and some could hang CI instead of failing. The change can merge, but tightening these tests is worthwhile follow-up.

Full details: Provider Data Stays Siloed

Explanation

No changed behavior leaks provider or account identity data. The new forecast store keys in-memory history by ForecastScope { provider_id, account_key }, and persisted history uses provider-specific files plus hashed account keys (rust/src/core/session_equivalent_forecast/history.rs, rust/src/core/quota_burndown.rs). Dashboard identity and account attachment code is unchanged. The provider-specific branches in rust/src/cli/cost.rs, rust/src/core/token_accounts.rs, and the split settings files preserve the base behavior; the token-account match arm set is identical between base and head. The only cost-branch change is tuple construction and shared result assembly, not cross-provider data routing.

Full details: Secrets Handled Safely

Explanation

No changed production path exposes a secret. Config dump already had the explicit --show-secrets behavior before this pull request, while the new tests verify default redaction. Changed credential paths use secure_file; the new settings save path calls secure_file::write_string. The deleted credential module had no runtime caller, and no changed code deletes another application's credential file or keyring entry. New logging records only non-secret errors, paths, or timing data. Credential-bearing test data is moved into test modules and is not a snapshot.

Full details: No Unapproved Dependencies

Explanation

No dependency manifests changed in the reviewed range. The base and head contain the same Cargo.toml, package.json, pnpm-lock.yaml, yarn/npm lockfile set, and pnpm workspace files. The PR adds no npm or yarn lockfile and does not change a pinned pnpm packageManager version.

Full details: Ui Changes Include Windows Proof

Explanation

The PR changes rust/src/settings.rs and adds rust/src/settings/persistence.rs, provider_accessors.rs, and start_at_login.rs; the check therefore applies. The available PR description reports Rust and desktop test results but shows no screenshots or fresh-Windows proof note. The description is explicitly truncated, so the omitted text could contain the required proof.

Resolution

Provide the complete PR description, or add screenshots or a proof note from a fresh Windows build.

Inline comments:
Review comments at @rust/src/cli/serve/tests/dashboard_routes.rs:
- Around line 398-410: Move the shared request/response roundtrip logic from
request_roundtrip_dashboard into a pub(super) helper in head_bound.rs that
accepts a ServeConfig. Update request_roundtrip in head_bound.rs and the
dashboard route tests to call that helper, removing the duplicated
implementation while preserving the existing timeout and response-drain
behavior.

Review comments at @rust/src/cli/tty_runner/tests.rs:
- Around line 242-248: Remove the redundant assertion in `test_enriched_path`,
since its non-empty fallback makes it pass regardless of the path contents. Keep
the existing non-empty assertion; only replace the redundant check if adding a
meaningful path-content assertion.

Review comments at @rust/src/codex_workspaces/indexer/tests.rs:
- Line 284: Extend the test around `snap.redact_for_privacy()` to assert that
`snap.sessions[0]` has its title and `cwd` redacted, in addition to the existing
assertions for `snap.projects[0].top_sessions[0]`.
- Line 49: Update the dated fixtures in all three tests to use the date derived
from the cost bucket scan zone, and pass the same fixed `now` to each
`load_snapshot_at` call so the fixture date is within the scan range.

Review comments at @rust/src/core/hook_transition/tests.rs:
- Line 325: Update the suppression test containing HookProviderStatus::Unknown
so usage rises from below 80% to 100% while resets_at advances; assert that only
QuotaReset fires, ensuring the test exercises suppression of upward QuotaLow and
QuotaReached events.
- Line 276: Update the second observation in this test to keep usage at 100%,
matching the first observation, so the test verifies reset-boundary advancement
without a usage drop triggering QuotaReset. Preserve the existing lane key,
timestamp, and other arguments.

Review comments at @rust/src/core/session_equivalent_forecast/tests.rs:
- Around line 271-275: Update the nearby-reset and out-of-order cases around
SessionEquivalentBurnEstimator::estimate to start from a history with at least
three completed groups that produces an estimate; then alter only the reset
times for each case and assert the expected estimate or rejection, so each
assertion tests grouping or ordering rather than the minimum sample count.
- Line 429: In the test loop, insert more than the ring capacity of 56 samples,
then assert that only 56 are retained and that the first retained sample is the
expected post-eviction sample.

Make the grouping assertions distinguish valid and invalid histories.

The nearby-reset case expects None because it has only one completed group. The later out-of-order case also has fewer than the required three groups. Both assertions can pass without testing the intended grouping or ordering behavior. Start with a history that produces an estimate, then vary its reset times and assert the resulting estimate or rejection.

Update the nearby-reset and out-of-order cases around
SessionEquivalentBurnEstimator::estimate to start from a history with at least
three completed groups that produces an estimate; then alter only the reset
times for each case and assert the expected estimate or rejection, so each
assertion tests grouping or ordering rather than the minimum sample count.

Fixed on simplify/rust-core-cli (head bfb85179e). The grouping test now starts from a history that produces an estimate (three distinct session groups), then moves group 2 inside the 120s tolerance and asserts rejection, and separately asserts the ordering reject for backward resets beyond tolerance.

@Finesssee, I inspected bfb85179. The nearby-reset case now starts from a baseline with three samples.

The ordering case still uses a separate history with only two session entries at Line 278–279. It can return None from insufficient samples even if the ordering check is removed.

Please derive the ordering case from the passing three-group history, then introduce backward resets beyond the tolerance. This part of the finding remains open.

Assert fields from the production JSON payload.

This test serializes a JSON object that it constructed itself. It passes even if build_json_payloads stops emitting historyCoverageIsEstablished or modelPricingCompleteness. The test at Line 70 has the same problem for the Claude null value. Build both payloads with build_json_payloads, then assert the field values on its results. These fields are part of the output compatibility this PR aims to preserve. Based on learnings, exact assertions on serialized values provide stronger regression coverage than substring checks.

Add an outer timeout to the deadline tests' read_to_end calls.

roundtrip_with_config says that strict outer timeouts turn a hang into a test failure. Three tests read without that bound:

  • incomplete_head_eof_gets_pinned_400 at Line 161.
  • silent_client_is_closed_at_total_deadline at Line 178.
  • trickling_bytes_do_not_reset_total_head_deadline at Line 222.

These tests guard the total head deadline. Suppose a regression stops the server from enforcing that deadline. The server then never sends FIN, so read_to_end blocks forever. The elapsed < 2s and elapsed < 2.5s assertions never run, and the test stalls CI instead of failing with a clear message.

Wrap each read in tokio::time::timeout. Use the same pattern as roundtrip_with_config.

♻️ Proposed fix
-    client.read_to_end(&mut response).await.unwrap();
+    tokio::time::timeout(Duration::from_secs(10), client.read_to_end(&mut response))
+        .await
+        .expect("client read timed out")
+        .unwrap();

For Line 222:

-    let _drained = client.read_to_end(&mut response).await;
+    let _drained = tokio::time::timeout(
+        Duration::from_secs(10),
+        client.read_to_end(&mut response),
+    )
+    .await
+    .expect("server never closed the trickling connection");

Count dispatched toasts in the refresh-loop test.

If the session call clears the weekly key and the weekly call sends another toast, before and after are both true. weekly_fires stays at 1 across all 30 cycles, so this test passes during the repeated-toast regression described at Lines 477–478. Assert that manager.toasts contains one weekly toast after the loop instead of counting key transitions.
