fix(server): preserve usage-limit recovery across notification wakes - #32454
Fixes#32286. A usage-limited thread can already have automatic recovery armed when a later background notification starts a run that completes before the reset. Selecting only the latest executed run hides the original failure, so recovery never dispatches. The same underlying failure is described in #16815.
This PR now includes the production fix; it is no longer a test-only, intentionally failing draft.
Change
Preserve the most recent usage-limit failure through notification-started runs that complete at or before its reset. User-started completions and completions after the reset remain authoritative.
Apply the same selection rule to SQL recovery candidates, shell projections, shared runtime state, and continuation validation. Updating SQL alone would leave the continuation rejected by the orchestrator.
Keep manual Resume and Stop aligned with that recovery source, including a Stop before automatic arming. Preserve request identity and duplicate-dispatch protection.
Retain bounded recovery evidence in history snapshots so a long notification sequence does not silently hide the resumable run from clients.
Extend the existing recovery scenario table with notifications before and after arming, Stop before and after arming, explicit rearming, and idempotent continuation. The original wake-after-arm assertions remain covered; no test was disabled or weakened to obtain a passing result.
No provider protocol, failure-classification, database migration, or UI layout change is included. Notification dispatch itself is not blocked by this change.
The production implementation is adapted from @yspreen's #31219, pinned at 5de22fa1f8ea2b3d03c73e9bfe40641cce1e41f7, which builds on #22775. Credit for that implementation remains with its original contributors. It was applied to this branch's current 38e7eec391ff400e2b268a6da68a78308fa5ff4a baseline with three-way integration, preserving newer upstream changes and this PR's regression coverage. This branch no longer needs to wait for another PR to merge before its tests pass.
The fork-only validation workflow and helper scripts are not included in this PR. The actual PR contains nine changed source/test files and no CI configuration changes.

The negative-control command intentionally selects four scenarios with -t; the other 117 cases are unselected in that diagnostic run only. The following fixed-source run executes and passes all 121 cases. This is not a change to CI skip rules or test expectations.
The run's recovery-integration-evidence artifact includes the exact candidate SHA, patch, source snapshot, and baseline/fixed/check logs. Earlier upstream CI also independently reproduced the original regression: failing pre-fix run.
Not verified: a live Claude quota-exhaustion incident, macOS/desktop/mobile runtime behavior, or visual UI rendering. Validation uses synthetic persisted events and test doubles; no paid provider calls were needed. Full upstream CI on the newly pushed head is separate from the successful focused and changed-file verification above.
Retained as a draft pending upstream CI and maintainer review; nothing has been merged.
Adapt the recovery selection, command validation, client Resume and bounded snapshot changes from yspreen/t3code PR pingdotgg#31219 (5de22fa), based on the earlier work in pingdotgg#22775. Keep the independently added wake-after-arm regression intact.

Extend the existing recovery matrix without disabling assertions: notifications before and after arming, Stop before and after arming, explicit rearm and idempotent continuation.

test(server): reproduce armed usage-limit recovery lost after notification wake
fix(server): preserve usage-limit recovery across notification wakes
Nov 7, 2026
Usage-limit recovery now accounts for completed notification-started runs when selecting a blocked run and recovery candidates. Windowed projections retain evidence used to identify the blocked run. Orchestration and client runtime use that run when validating recovery, handling stops, and deriving resumable runs.
Changes: Usage-limit recovery
Layer / File(s)
Summary
Filter qualifying notification wakes packages/shared/src/orchestrationV2ThreadError.ts, apps/server/src/orchestration-v2/ProjectionStore.ts, apps/server/src/orchestration-v2/ProjectionStore.test.ts, apps/server/src/orchestration-v2/runtimeLayer.test.ts
The shared selector and server queries exclude completed notification-started runs that finish at or before the usage-limit reset when selecting blocked runs and recovery candidates. Tests cover shell selection, recovery scenarios, and query-plan lookups.
Retain recovery evidence in bounded projections apps/server/src/orchestration-v2/ProjectionStore.ts, apps/server/src/orchestration-v2/ProjectionStore.test.ts, apps/server/src/orchestration-v2/threadHistoryPaging.ts, apps/server/src/orchestration-v2/threadHistoryPaging.test.ts
Windowed projections add the blocked run, its root error, and evidence from later runs. History paging retains compact recovery items within its byte budget. Tests check blocked-run selection and retained item sizes.
Use the blocked run in recovery consumers apps/server/src/orchestration-v2/Orchestrator.ts, packages/client-runtime/src/state/threadExecution.ts, packages/client-runtime/src/state/threadExecution.test.ts
Orchestration and client runtime select the usage-limit-blocked run before falling back to the latest executed run. Tests cover notification wakes before and after recovery is armed, stop handling, and resumability.
pingdotgg/t3code#16815 — The issue reports completed background-notification runs hiding a usage-limit failure and preventing recovery. This change updates recovery selection for those notification wakes.
pingdotgg/t3code#24895 — The issue concerns the recovery candidate query changed here, although this change addresses selection behavior rather than the reported read-performance objective.

Merge Risk: Low · up to e9352
Usage-limit recovery now survives notification-started runs. Stop and command paths on long-lived threads with many notifications may load more data than necessary, adding some latency. This is a bounded follow-up rather than a merge blocker.

Explanation
[#32286] The SQL candidate and shell queries exclude completed notification-started runs that finish by the latest usage-limit failure reset (ProjectionStore.ts). The shared usageLimitBlockedRun rule applies the same filter, and the orchestrator uses it for continuation validation and Stop (orchestrationV2ThreadError.ts, Orchestrator.ts). Snapshot loading retains the limited run and notification-start evidence for bounded client projections. Added regression tests cover wake/Stop scenarios and snapshot recovery evidence. This addresses the reported lost-recovery case. The issue's separate observation about a wake being recorded as completed is not an acceptance requirement to change notification dispatch or run status.

Avoid loading all notifications in command projections
On threads that accumulate provider or delegated notifications, this makes every readCommandProjection call select and decode every notification row, including the unbounded detail field in OrchestrationV2Notification. This helper is used by message dispatch and queued-run startup, so routine commands now become O(total notification history) and can repeatedly read many megabytes on long-running agent threads; load only compact run-start evidence, or restrict it to the relevant runs, instead of widening this global projection.
The reason will be displayed to describe this comment to others. Learn more.
Scope Stop's recovery read to relevant runs
Whenever Stop or a held interrupt runs on a long thread, this unconditional read fetches and decodes all historical user messages, errors, and notifications before checking whether any failed run needs recovery. The previous path only read errors for the latest failed run, so the user's Stop action can now be delayed by the entire transcript, even for an ordinary active or completed run; determine the candidate first and query only its error plus the relevant wake starts.
The reason will be displayed to describe this comment to others. Learn more.
Stub notification evidence before decoding full payloads
For a usage-limited thread with many wake notifications, this reads and schema-decodes the complete payload_json for as many as 200 retained starts, even though limitRecoveryItems later removes each notification's unbounded detail to honor the page budget. Opening such a thread—or even the rowLimit: 1 snapshot used by guest-message intake—can therefore allocate and read many megabytes before producing a bounded result; construct compact stubs in this query or enforce a byte cap before decoding full payloads.
1294-1294: Trivial · Performance & Scalability · Heavy lift
Consider bounding the new unbounded notification read on hot paths.
readCommandProjection runs in every command transaction. This change adds every notification item of the thread to that read, and each item is fully decoded. The code already read all user_message and error items. PR-watch, monitor, and delegated-task wakes can produce hundreds of notifications on a long-lived thread. Delegated-completion notifications also carry detail. Every command on that thread then pays for the read.
holdStoppedThread (lines 11116-11120) adds the same thread-wide read to every Stop.
Selection only needs the first user_message or notification item of each run root, plus the root errors. Consider a dedicated ProjectionStore read for this evidence. It would work like the SQL first-input subquery in isLimitedWake. readCommandProjection and holdStoppedThread could then skip loading all items.

@saiananth1 thanks for picking this up. I checked whether anything from here should go into #31219, and I don't think anything should.
The production changes are #31219 at 5de22fa, line for line. Since then #31219 got one more commit, 88d3d6a, which makes Stop read only the turn items that can hide a limited run instead of every user_message, error and notification item in the thread. This branch doesn't have it. It also drops the near-miss cases in ProjectionStore.test.ts (a wake completed after the reset, a run a user message started). Those are the only tests that catch the rule hiding real work.
The new piece is the after-arm ordering (wake-after-arm, stop-after-arm-wake). I ported wake-after-arm into #31219's scenario table to try it. It passes with the fix and fails without it, but it repeats wake-hidden. Three reasons:
Writing a run.created / run.updated never touches limitRecovery, and arming never touches runs. After arming, both orderings leave the same rows.
The shell query, getLimitRecoveryCandidates and the continuation check in Orchestrator.ts all pick the latest run at read time, so event order can't change what they see.
Reverting only the arm-validation part of the fix makes wake-hidden and stop-before-arm-wake-hidden fail while wake-after-arm still passes. No partial revert fails wake-after-arm by itself.
So the armed-then-woken case from #32286 is already caught by wake-hidden. I'd suggest closing this in favor of #31219 so #16815 and #32286 have one PR to review. If you see an order-dependent path I missed, point me at it and I'll add a case.
merged current main (merge commit, no rebase). one conflict in ProjectionStore.ts: kept main's presentedShellRunId join and this PR's latestFailureJoins.
checks on a testbox: format, lint, knip, typecheck (35 packages) pass; runtimeLayer, threadHistoryPaging, threadExecution and the other changed-file tests pass (252). ProjectionStore.test.ts "reads a fixed SQL turn-item window" fails there only because the box runs Node 24 without StatementSync.stat; it is main's test and CI runs Node 26.
Earlier verification
Verified in a real dev environment
partial verification of e23f8498d83e1ab6d0f0350246f837f5b6a752db on linux. this does not establish that the quota-reset fix works end to end.
installed and ran github/main (fa2f4ff2a2) in a separate worktree, stopped its server, then installed and ran the exact pr head with isolated state. drove the web app with repository playwright and /usr/bin/google-chrome. created the project/thread through the app and used real codex gpt-6.1-sol turns through the local proxy, with no injected events, mocks, fixtures, or demo scenario.
normal message completion worked on both revisions. on the pr, stop interrupted an active provider tool call; clicking "resume thread" dispatched "Continue where you left off." and the real provider completed with STOP_CHECK_COMPLETE.
blacksmith checks also passed: 24 selected recovery/runtime cases, plus all 112 cases in ProjectionStore.test.ts, threadHistoryPaging.test.ts, UsageLimitRecoveryWorker.test.ts, and threadExecution.test.ts. these automated cases use their existing test doubles and are separate from the real-provider evidence above. no source changes were made.
Not verified
the original bug could not be reproduced on main. the healthy proxy did not produce a genuine usage-limit failure with an exhausted rate-limit window and future resetAt. that is required to exercise this fix. i did not manufacture the event or exhaust the account.
therefore recovery after a pre-reset notification wake, automatic continuation at reset, stop/rearm in that limited state, and the after-reset/user-completion supersession cases remain unverified in the running app. desktop/native mobile clients and other providers were not exercised. this is a partial result, not a merge-readiness claim.
Stop read every user message, error and notification in the thread. It now
reads the latest failed run's errors, then the inputs of runs completed
before that failure resets. The limit-evidence query drops notification
detail, which paging strips anyway.
Limit the wake-input read in holdStoppedThread to runs that can hide the failure.
wakeRunIds holds every completed run whose completedAt is at or before resetMs. A run that ended before the failed run cannot replace it as the latest executed run, because runRanAfter orders by completedAt. The read at Line 11340 still loads user_message and notification items for those runs. If the newest failure is old, or the thread has a long history before the reset, Stop loads the full text of every earlier user message and the full detail of every notification. This read runs inside the Stop command transaction.
Add a lower bound so that only runs completed at or after the failed run's completedAt are read. Use POSITIVE_INFINITY when failed.completedAt is null: an unfinished run counts as latest, so no wake can hide it.
As per coding guidelines: "Make sure all changes are considerate of performance impact."

Keep #31219 as the single review candidate. Its current head has a clean conflict check against current main and all 30 reported checks passing. Direct diff comparison shows identical production additions in the orchestrator, shared selector, client continuation selector, and history paging; the recovery SQL is also equivalent apart from this PR stripping notification detail before decoding retained evidence. The competing PR additionally covers user-started completions and notification completions after reset in both SQL and memory shells, protecting the boundaries where real work must supersede recovery. This PR's explicit before/after-arming scenarios cover the same persisted-state selection rule. Its notification-detail optimization is useful to carry into the retained PR, but does not warrant a second implementation of the same recovery fix. Main still lacks the change.

Problem
Fixes #32286. A usage-limited thread can already have automatic recovery armed when a later background notification starts a run that completes before the reset. Selecting only the latest executed run hides the original failure, so recovery never dispatches. The same underlying failure is described in #16815.
This PR now includes the production fix; it is no longer a test-only, intentionally failing draft.
Change
wake-after-armassertions remain covered; no test was disabled or weakened to obtain a passing result.No provider protocol, failure-classification, database migration, or UI layout change is included. Notification dispatch itself is not blocked by this change.
Scope and attribution
One underlying recovery problem: #32286 / #16815. See the existing maintainer discussion.
The production implementation is adapted from @yspreen's #31219, pinned at
