Problem

When a run stops on a usage limit, the auto-settle sweep can settle the thread in the same second. The run that kept the thread active has ended, and settle-on-merge passes whenever the PR merged after the last user-authored message. That is common when PR-watch or system wakes keep a thread working without a new user message. Settled threads are deliberately excluded from limit recovery, so "Resume at reset" and "Snooze until reset" then always fail, and the thread silently drops out of the active list right when it needs attention.

Seen in a real thread: run 4 failed with usage_limit at 20:46:13Z, and ThreadSettlementServiceV2.sweep dispatched thread.auto-settle at 20:46:13Z. Four recovery attempts at 20:49 to 20:51Z were all rejected. The user never sent a thread.settle.

Change

A usage limit interrupts work rather than finishing it, so the sweep now leaves such a thread alone, the same way it already does for pending runtime requests and link requests.

getSettlementCandidates (ProjectionStore.ts) skips a thread whose latest executed run failed and whose latest root error is usage_limit. It uses the same run selection as the shell's blocked join and getLimitRecoveryCandidates, so a message queued behind the limit does not hide it. Like threadErrorSummary, a newer session error that differs from the failure message replaces the limit, so the thread is then treated like any other failed thread. A cheap EXISTS on usage-limit error items runs first, so other threads skip the per-thread run sort; on a real 834-thread database the clause costs about 3 ms of CPU.
isAutoSettlementCandidate applies the same rule to shell threads (status: "failed", lastErrorClass: "usage_limit"), so the candidate and the shell keep agreeing. ProjectionSettlement.test.ts asserts that parity.

Only an interrupted thread is affected. A thread that failed for any other reason still settles as before, and once the user sends a message or recovery resumes the thread, the latest run is no longer a usage-limit failure, so it becomes eligible again.

Scope and approval

Fixes pingdotgg/t3code#28362. A small fix for an obvious bug: the settle sweep defeats the existing usage-limit recovery feature. It adds no setting or new behavior beyond keeping these threads unsettled. The banner and error-message side of the same report is a separate PR.

Verification

ThreadSettlementService.test.ts › never settles a thread stopped by a usage limit: fails on main (expected true to be false) and passes here.
ProjectionSettlement.test.ts › sql: discovers settlement work with the same activity and background semantics as the shell now seeds a usage-limited thread, a thread with a message queued behind its limit, and a usage limit that ended after a newer failed run, all excluded, plus a provider_error thread and a limit superseded by a differing session error, both eligible. It fails on main, and the queued, out-of-order and session-error cases each fail on the revision before their fix. It passes here, with the shell and the SQL candidates agreeing.
ThreadSettlementService, ProjectionSettlement, SubagentProjection, PeerLinkRequests and runtimeLayer tests, plus ProjectionStore.test.ts: 212/212 pass.
vp run check:changed upstream/main: format, lint, knip, graphql, typecheck and tests pass.
Not checked: a live provider hitting a real limit after the fix. The trace above is from before it.

getSettlementCandidates returns usage-limit-blocked threads as settlement candidates when a newer queued or cancelled run is selected as r; this lets settlement hide the recovery controls that the shell displays for the blocked run. The exclusion checks only r, while shellThreadStateFromRow can present the usage-limit failure from an earlier blocked run. Apply the exclusion to the same blocked-run selection used by the shell.

Confirmed and fixed in 54eada734f. The exclusion only checked the newest run by ordinal, so a message queued behind the limit (status queued, ordinal 2) became r, and the sweep could settle a thread the shell still presents as limited through its blocked join.

The exclusion now uses the same selection as the shell's blocked join and getLimitRecoveryCandidates: the latest executed run (skipping queued and never-started cancelled, ordered as in runRanAfter), status failed, whose latest root error item is usage_limit. A cheap per-thread EXISTS on usage-limit error items runs first, so other threads skip the run sort.

ProjectionSettlement.test.ts now seeds a queued-behind-limit thread (a failed usage_limit run plus a queued run). On the previous SQL it is wrongly eligible (9 vs 8 expected). With the fix it is excluded on both the candidate and the shell side, and 212/212 tests pass across the settlement, projection and runtime-layer suites.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Usage-limited threads are excluded from automatic settlement to preserve recovery controls, changing their default lifecycle behavior. Human review must confirm that policy; the unresolved finding also reports a newer-run scenario that can still hide those controls.

Walkthrough

The projection query excludes qualifying usage-limit failures from settlement candidates. The auto-settlement predicate also rejects failed threads whose lastErrorClass is usage_limit. Tests cover provider errors, provider-session errors, queued runs, and run completion order.

Changes: Usage-Limited Settlement Exclusion

Layer / File(s)	Summary
Filter projection settlement candidates `apps/server/src/orchestration-v2/ProjectionStore.ts`, `apps/server/src/orchestration-v2/ProjectionSettlement.test.ts`	The projection query excludes qualifying usage-limit failures based on the latest executed run and provider-session error. Tests cover queued runs, completion-time ordering, and provider-session errors.
Exclude usage-limited auto-settlement candidates `apps/server/src/orchestration-v2/ThreadSettlementService.ts`, `apps/server/src/orchestration-v2/ThreadSettlementService.test.ts`	The auto-settlement predicate rejects failed threads with `lastErrorClass` set to `usage_limit`. Tests distinguish this case from `provider_error`.

Explanation

The title "fix(server): a usage-limited thread no longer auto-settles" states the main change. The change keeps threads stopped by a usage limit from being auto-settled by the settle-on-merge sweep. It uses a conventional commit prefix and plain language, and the scope (server) matches the changed files under apps/server.

Full details: Linked Issues check

Explanation

Issue [#28362] requires the auto-settlement defect to be fixed for usage-limited threads. ProjectionStore.ts excludes threads whose latest executed failed run has root error usage_limit, including queued and out-of-order runs. ThreadSettlementService.ts applies the matching lastErrorClass: "usage_limit" rule. Tests cover recovery eligibility and preserve settlement for other failures. The banner and error-message defects are separate scope identified in the issue.

Full details: Out of Scope Changes check

Explanation

The changes remain within the settlement objective in [#28362]. The SQL candidate query, shell candidate check, and focused tests keep usage-limit behavior consistent. Tests for provider failures and superseding session errors support the required unchanged behavior. No unrelated product change is shown.

Match the shell’s usage-limit run before allowing settlement.

Held queues can execute out of ordinal order. If a lower-ordinal usage-limited run completes after a higher-ordinal provider-error run, the shell presents the usage limit because it selects by completion order. getSettlementCandidates selects by ordinal, so it can miss the exclusion, return lastErrorClass: null, and allow auto-settlement once the other eligibility conditions pass.

Select the effective failed run with the shell’s completion-order rule before applying the usage_limit exclusion.

🤖 T3 Code agent responding on behalf of EhsanulHaqueSiam

Valid against 3e69b685b9, which this review covered, and already fixed in 54eada734f. The exclusion now selects the latest executed run with the shell's completion-order rule (completed_at IS NULL DESC, completed_at DESC, ordinal DESC, skipping queued and never-started cancelled), then checks that run's latest root error for usage_limit. It no longer uses ordinal order.

b2c9981a74 adds your exact case to the ProjectionSettlement.test.ts parity test: a lower-ordinal usage_limit run that ends an hour after a higher-ordinal provider_error run. On 3e69b685b9 the test fails (10 eligible vs 8 expected; this case and the queued-behind-limit case leak through). On the current head it passes, with the SQL candidates and the shell agreeing.

CcoderabbitaiBot9d ago

@EhsanulHaqueSiam The supplied current code confirms the fix. The usage-limit exclusion now uses the shell’s completion-order rule, skips queued and never-started cancelled runs, and checks the selected run’s latest root error.

This addresses the original finding. The reported regression test covers the out-of-ordinal completion case and SQL/shell parity. I did not independently run the test.

Align settlement SQL with session-error normalization.

A usage_limit terminal followed by a differing provider-session last_error does not force any other settlement hold. The thread can have no active run, pending request, waiting link, queued turn start, background hold, guest message, or active snooze. The shell then derives lastErrorClass: null, so isAutoSettlementCandidate allows settlement. The SQL still excludes the thread because it compares the root error directly to usage_limit.

Apply the same session-error normalization to the SQL predicate. Keep the exclusion when the session error is absent or matches the usage-limit failure, and allow the mismatch case to reach settlement.

Note

🤖 T3 Code agent responding on behalf of EhsanulHaqueSiam

Valid, and fixed in 1b7badf4fd. threadErrorSummary drops the failure when the provider session's lastError differs from its message, so the shell shows no usage limit, the banner and getLimitRecoveryCandidates skip it, yet the SQL still held the thread.

The predicate now evaluates the blocked run's latest root error as failure.class = 'usage_limit' AND COALESCE(sessionLastError = failure.message, 1), using the same session lookup (newest session bound to the thread's provider instance) as the shell and the recovery query. The exclusion stays when there is no session error or it matches, and lapses when it differs.

ProjectionSettlement.test.ts adds a session-error-after-limit thread (a usage_limit failure plus a bound session with a different lastError). On b2c9981a74 it is wrongly excluded (8 eligible vs 9 expected). With the fix it is eligible on both the SQL and the shell side. 212/212 pass across the settlement, projection and runtime-layer suites.

@EhsanulHaqueSiam The supplied ProjectionStore.ts confirms the fix. The predicate uses the newest bound session for the thread’s provider instance. It retains the usage-limit exclusion when lastError is absent or matches failure.message. When lastError differs, this predicate no longer blocks settlement.

This addresses the finding. The reported session-error-after-limit regression case covers the mismatch. I have not independently run the reported 212 tests.

fix(server): a differing session error lets a usage-limited thread settle1b7badf

Add coverage for a matching provider-session error.
createFailure sets the usage-limit failure message to "usage_limit". The test covers an absent session error and a different error ("Session crashed."), but not a session error equal to "usage_limit". If the SQL condition regresses to absent-only, that regression passes the current assertions. Add a matching-error fixture and keep it out of the expected eligible set.

_Nitpick Cover the reverse completion order in the SQL fixture.

298-318: External image Trivial · Functional Correctness · Quick win
Cover the reverse completion order in the SQL fixture.
The fixture covers a lower-ordinal usage_limit run that completes after a higher-ordinal provider_error run. It does not cover a lower-ordinal provider_error run that completes after a higher-ordinal usage_limit run. Add this case and assert that the thread remains eligible. This distinguishes completion-time selection from ordinal selection.

8 Extend the ProjectionSettlement SQL fixture with the reverse completion-order
9 case: have a higher-ordinal usage_limit run complete before a lower-ordinal
10 provider_error run, then assert that the thread remains eligible. Keep the
