Provider usage and rate limits currently appear as generic failures in V2. This ports the Limited state from #10550 onto V2’s structured provider failures and current-run projections.

Stacked above #2829, targeting t3code/codex-turn-mapping. The diff contains the provider-limit port and reset metadata needed by the recovery layers.

Codex, Claude, and Grok classify explicit native limit signals at the adapter boundary. Other adapters retain their existing failure behavior.
Shell and detail state derive the classification from the current failed root turn. Recovery, replacement failures, new attempts, and new runs clear stale classifications.
Web, desktop, and mobile show Limited with warning styling while preserving the provider explanation and attention notifications.

Adapted from Vitalii Yehorov’s original work in #10550, #7165, #10321, and #10473. The commit retains his co-author attribution. Reset times are normalized at the Codex and Claude adapter boundaries and carried in persisted failures and shell/detail state. Unknown reset times remain nullable. Auto-resume is a separate layer in #12686.

Validation: 637 focused tests passed across 13 files; scoped server, contracts, shared, client-runtime, web, and mobile typechecks passed; scoped lint, formatting, and whitespace checks passed. After the review fix for recovered retry markers, both affected suites passed again (104 tests), with web/mobile typechecks and scoped lint. Coverage includes native limit signals, superseding errors, recovery, root/child isolation, SQL/memory projection parity, and client notifications. The maintainer subsequently authorized browser verification. The integrated stack passed 466 focused tests across eight files, with scoped typechecks and lint. An isolated live browser using a deterministic Codex protocol peer confirmed Limited presentation and reset-based recovery. Native mobile was typechecked, not exercised on a device.

Summary by CodeRabbit

New Features
- Added a Limited status for threads stopped by provider usage or rate limits.
- Usage-limit errors now show “Usage limit reached,” warning styling, provider details, and reset information when available.
- Limited threads remain visible in the sidebar and work history, including after retries or recovery.
- Notifications identify limited threads.
Bug Fixes
- Improved error handling to display current root-run failures accurately without stale errors.
Documentation
- Documented the Limited status and retry or provider-switch guidance.

Integration verification: refreshed against current v2 without including its PR into main. Focused tests cover provider limits, recovery, snooze, scheduler behavior, contracts, and transcript presentation. The latest v2 turn-start history query now uses the existing SQL parameter helper; an empty run selection returns no history.

Latest v2’s targeted startup read omitted checkpoint scopes owned by an earlier root and reused by a queued turn. The same provider-switch failure reproduced on v2 without this stack. The integrated read now selects scopes through the current root’s checkpointScopeId. The SQL/memory regression, both failed queued-provider flows, and all six replay cases that failed in CI pass; scoped server typecheck and lint pass.

Fixed in 4daa4466ceb. Completed usage-limit retries no longer receive runtime.warning in the web work log, and mobile shows a recovery check instead of a warning marker. The focused web/mobile suites passed (104 tests), along with scoped typechecks and lint.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This is a broad runtime behavior change that classifies provider failures, persists reset metadata, changes thread state and notifications, and updates both web and mobile presentation across 39 files. The cross-layer provider and projection changes make this unsuitable for automatic approval despite the accompanying tests.

📝 Walkthrough

Walkthrough

The change classifies provider usage-limit failures, propagates their status and reset metadata, and presents them as limited with warning styling across web and mobile interfaces.

Changes

Usage-limit classification

Layer / File(s)	Summary
Error contract and runtime derivation `packages/contracts/...`, `packages/shared/...`, `packages/client-runtime/...`	The contracts and runtime state retain `usage_limit` and select the latest root-provider failure for the current thread run.
Provider failure classification `apps/server/src/orchestration-v2/Adapters/...`, `apps/server/src/orchestration-v2/ProviderFailure.ts`, `apps/server/src/provider/...`	Claude, Codex, and Grok classify supported rate-limit failures as `usage_limit` and preserve failure details and reset timestamps through retries and terminal events.
Classified shell projection `apps/server/src/orchestration-v2/ProjectionStore.ts`, `apps/server/src/orchestration-v2/ProjectionStore.test.ts`	SQL and memory projections combine root-provider and provider-session errors, expose `lastErrorClass` and `usageLimitResetAt`, and test replacement, recovery, isolation, and new-attempt behavior.
Web status and error presentation `apps/web/src/components/...`, `apps/web/src/session-logic.ts`, `docs/user/thread-sidebar.md`	Web status logic, banners, timelines, notifications, retry messages, tests, and documentation distinguish limited threads from ordinary failures.
Mobile status and activity presentation `apps/mobile/src/features/threads/...`, `apps/mobile/src/lib/threadActivity.ts`, `apps/mobile/src/lib/threadActivity.test.ts`	Mobile lists, work logs, and activities display limited statuses, warning styling, usage-limit labels, and recovery behavior.

Reuse the retained failure when the completion code matches.
When turn/completed supplies failureCode, the current guard always rebuilds the failure. A preceding non-retryable error notification can contain richer additionalDetails, so terminalization replaces that provider explanation with the generic completion message.
Reuse previousFailure when both the native message and failure code match.

🟠 Major · Preserve the reset time captured for deferred terminal events. · CodexAdapterV2.ts:4714

Preserve the reset time captured for deferred terminal events.
makeRootTerminalEvent already records failure.resetAt for the stopped turn. This line recalculates it every time emitRootTerminal runs. If a failed root terminal waits for an active descendant, a later account/rateLimits/updated event can replace the original reset time before emission. Reuse event.failure.resetAt when present, and calculate a value only when it is absent.

fix(v2): preserve captured Codex limit failures6922e6e

JJulius MarmingeSep 20, 2026

Fixed both verified outside-diff findings in 6922e6ef4c0: matching terminal message/code preserves the detailed non-retryable failure, and deferred root emission preserves the reset captured before a child drains. Two native replay regression cases cover these paths; all 92 Codex adapter tests and scoped server typecheck/lint pass.

A subagent's later turn does not clear its prior entry in limitedTurnItems, so a subsequent account/rateLimits/updated notification re-emits the stale usage-limit error even after the child recovers; the entry also remains for the rest of the session. Apply the same cleanup when creating subagent turn contexts, or centralize it for every new turn.

Verified against finalizeCodexTurn: only contexts with subagent === null call emitOrDeferRootTerminal, and only emitRootTerminal inserts into limitedTurnItems. Subagent failures never enter this map, so their later turns cannot re-emit a stale mapped failure. No cleanup change is needed.
