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, so nothing holds it. Settle-on-merge passes whenever the PR merged after the last user-authored message, which is common when PR-watch or system wakes keep a thread working without a new user message. Inactivity settling hits the same thread when the reset is further out than the inactivity window. Settled threads are excluded from limit recovery, so "Resume at reset", "Snooze until reset" and an armed auto-resume all stop working, and the thread 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.
  • isAutoSettlementCandidate applies the same rule to shell threads (status: "failed", lastErrorClass: "usage_limit"), so the candidate and the shell agree. Subagents are the exception: they reach the sweep only once their parent is put away, so abandoned limited subagents still settle for cleanup.

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

Why "never settle" rather than "settle after the reset"

A limited thread waits on the user, like a pending request, so it is handled the same way: it stays visible until someone acts, and the user can still settle it by hand. Exempting it only until the reset would need the reset time in both the SQL and shell candidates, plus a grace window so the sweep cannot settle the thread in the minute before auto-resume fires. That is more code for the case of a limited thread nobody returns to.

Scope

Fixes pingdotgg/t3code#28362 (auto-settle on PR merge settles a usage-limited thread, so "Resume at reset" and "Snooze until reset" always fail) and pingdotgg/t3code#18928 (inactivity auto-settle cancels a pending usage-limit auto-resume). This is one bug: the settle sweep defeats the existing usage-limit recovery. It adds no setting and no new behavior beyond keeping these threads unsettled. The banner and error-message side of #28362 is #28360.

Verification

  • ProjectionSettlement.test.ts › sql: discovers settlement work with the same activity and background semantics as the shell 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 (97cfc07759) and passes here.
  • vp run check:changed origin/main: format, lint, knip, graphql, typecheck and 107 tests pass.
  • Live, through the real Codex adapter: the real codex CLI pointed at a localhost stub that answers 429 usage_limit_reached, on an isolated server home, with the server clock moved so the 1-day inactivity window applies. On main both threads auto-settle (one on PR merge, one after 3 idle days). On this branch neither does, and both keep auto-resume armed. The transcript and the script are in the comments.
  • Not checked: an armed auto-resume firing at a real reset time, and a first-party Claude or ChatGPT account hitting a real limit. On main, limitRecoveryCommand returns nothing for a settled thread, so the armed resume cannot fire there; this is from the code, not observed.

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.

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.

Full details: Description check

Explanation

The description has strong content on the problem, change, scope, and verification. It fails the template in two places. First, the Verification section lists focused tests and a repo check with results, but the live test evidence is only referenced as comments that are not in the description. Second, the title line is missing, and the template asks for a conventional commit title, which the description does not supply. The Problem, Change, and Scope sections are complete. The description is mostly complete, but these gaps keep it from a pass.

Resolution

Add a conventional commit title in plain language, such as "fix(server): a usage-limited thread no longer auto-settles". Move or copy the live-verification transcript and script into the PR, or summarize the observed results in the Verification section, because the referenced comments are not part of the description. Keep the existing Problem, Change, Scope, and Verification content. The model and harness line is already present.

External image Unverified finding Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Check the latest root error, not any root error.

If one failed run has an earlier usage_limit root error and a later provider_error root error, this EXISTS excludes the thread. The shell selects the later error and treats the thread as provider-failed, so the two settlement paths disagree. Apply the shell’s error ordering before comparing the failure class.

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.

CcoderabbitaiBot14d 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.

🤖 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.

CcoderabbitaiBot14d ago

@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.

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.

The automated pipeline stopped on this pull request and will not merge it:

the fix is written and reviewed, but proving it needs something no worker has:

  • Permanent blocker: the reproduction needs a provider usage-limit interruption with scheduled recovery. The scenario runner explicitly cannot create a usage-limited run, and first-party Claude or ChatGPT OAuth usage, limit, and renewal flows are unavailable on this VM. Both inactivity-based and merged-PR settlement behavior remain unverified.

It stays open for a person to finish or close.

Note

🤖 T3 Code agent responding on behalf of EhsanulHaqueSiam

The usage-limited run can be created without first-party OAuth, and with it both settle paths reproduce on main and are fixed here.

The real codex CLI pointed at a localhost Responses stub that answers 429 usage_limit_reached (with x-codex-primary-* headers) fails the run through CodexAdapterV2 as usage_limit with a resetAt, and auto-resume arms. A test-only --import preload shifts the server's Date.now(), so the limit hits 3 days in the past and the 1-day inactivity window then applies. Each run uses a fresh, isolated T3 home. The merged-PR thread sits on the head branch of a same-repo PR that merged in the last 2 days, after the thread's message.

Same script, both checkouts:

main: both threads auto-settle. The merged-PR thread is settled before auto-resume can arm.

12auto-settle commands in trace: 0

Not watched live: the armed auto-resume firing at the real reset time. On main, limitRecoveryCommand returns nothing for a settled thread, so it cannot fire there.

The branch is updated with main. The only conflict was the new PR-watch check in isAutoSettlementCandidate, which is kept alongside the usage-limit check. vp run check:changed origin/main passes. ProjectionSettlement.test.ts fails on main (14 candidates vs 10 expected) and passes here.
