Problem

A usage-limit failure holds a thread's queued messages only until any later run on the thread executes. When provider A hits its limit with A-selected messages still queued and the user then completes a turn on provider B, the queue starts on its own. Each queued A message runs against A's still-active limit, fails with usageLimitExceeded, is consumed, and flips the thread back to A. Reported in #21705 and reproduced twice there with native provider errors and run timestamps.

The gate in usageLimitHoldsQueue reads A's latest session error but passes every run on the thread to usageLimitBlockedRun, which looks only at the thread's latest executed run. After B's success that run is B's completed run, so the gate returns false even though A's own latest run is still the usage-limit failure.

Change

usageLimitHoldsQueue now evaluates only the runs of the provider the queued message selects. When A's limited run is still the thread's latest run, the queue stays held as before. When another provider has run since, the queue stays held only while the reported reset time is still ahead, so a limit that has reset no longer pins messages queued for A (the stuck case @mkantautas found in the first review). The same helper guards both the automatic queue start in startNextQueuedRun and the explicit queue.resume command, so both paths follow the same rule. Each queued message keeps the account it was saved with, as the issue asks.

Scope and approval

Fixes #21705, accepted as a bug by @juliusmarminge in https://github.com/pingdotgg/t3code/issues/21705#issuecomment-6267394925. That comment confirms the latest-run check as the cause and notes that #21314, now merged, makes the hold provider-specific but still calls usageLimitBlockedRun on all runs, so it does not cover this sequence. One underlying problem, server only, no contract or UI change.

Not in this PR: delegated-completion wakes queued while the thread was on A still sit first in delivery order and hold the messages behind them until A's reset. That ordering predates this change and wants its own fix.

Verification

Regression test holds a limited provider's queue through another provider's turn until %s passes (one row for a known reset, one for an unknown reset) in apps/server/src/orchestration-v2/runtimeLayer.test.ts. It queues an A message behind a running A run, fails that run with a usage_limit error whose reset is an hour out, completes a B run, calls resumeQueuedRuns, and asserts the A message is still queued and that queue.resume is refused. It then advances the clock an hour and asserts the A message starts on A when the reset was known, and stays queued when it was not.

On main (fix reverted, test kept): fails with expected 'starting' to equal 'queued'.
With the fix: passes.
vp test run apps/server/src/orchestration-v2/runtimeLayer.test.ts apps/server/src/orchestration-v2/testkit/ProviderSwitch.integration.test.ts: 2 files, 145 tests passed on current main.
vp run check:changed: format, lint, knip, typecheck and the tests beside the change pass.

Not changed: after B succeeds, the thread's latest run is B's, so the usage-limit banner, Continue, and auto-resume for A's run no longer show. A held A message starts with the next queue start after its reset passes (a run ending, a cancel, or a send); nothing wakes the queue at the reset time itself. A limit with no reported reset stays held until the user sends on A or cancels the message, matching the recovery worker and banner, which also treat an unknown reset as a manual retry.

Not checked: a live two-account Codex reproduction. The fix changes only which runs the existing helper reads and when, so the end-to-end path is the one the test drives through the persisted orchestrator and fake provider.

Model and harness: Claude Fable 5.1 in Claude Code, reviewed independently by GPT-6.1 Sol (Codex) and Claude Opus 5.5. Reset-aware hold and its test contributed by @mkantautas.

Approvability

Verdict: Approved at 5335e95

Macroscope's review found this PR approvable — This is a narrowly scoped server bug fix that keeps a provider’s queued work held when a different provider completes successfully. It changes only the existing provider-specific usage-limit check and adds regression coverage for the reported sequence.

Walkthrough

The usage-limit queue check now evaluates runs for the selected provider and uses the current time to assess reset conditions. Queue-start and queue-resume paths pass that time to the check. Tests cover work on another provider and known, unknown, and invalid reset times.

Changes: Provider-specific queue holds

Layer / File(s)	Summary
Provider-scoped hold check and regression coverage `apps/server/src/orchestration-v2/Orchestrator.ts`, `apps/server/src/orchestration-v2/runtimeLayer.test.ts`	`usageLimitHoldsQueue` filters runs to the selected provider. It holds the queue when the limited run is the latest executed run, or when the latest provider failure has no valid reset time or its reset is in the future. Queue-start and queue-resume paths pass the current time. Tests cover work on another provider, reset-time cases, and queued-run state.

Merge Risk: External image Minimal · previous review f42e7

Queued work remains held for an unknown reset after another provider runs. No actionable merge-blocking risk remains.

Security architecture risk: External image Minimal · up to 5335e

The fix strengthens an existing queue hold rather than creating a new execution path. Activity on another provider can no longer release work held by the limited provider. No material security risk was identified in the change.

Retained concerns No architecture-level concerns identified.

Security review details

Security Blast Radius

observed — The changed decision consumes one thread projection and a requested provider-instance identifier. It selects that instance's latest session and filters candidate runs to the same identifier; it does not introduce a credential or execution-target selection mechanism.

Security Findings and Attack Paths

inferred — For the same projection and requested provider, filtering before latest-run classification cannot remove a hold that the previous implementation enforced. The changed predicate therefore does not create a new queue-release bypass through activity on another provider; it closes the previously demonstrated release sequence.

Trust Boundaries and Controls

observed — Usage-limit classification remains tied to the selected executed run's failed root-node error and compatible session error. Queued runs and cancellations that never started do not replace the executed-run outcome. Provider filtering does not remove these existing conditions.

Explanation

The reviewed changes modify server-side usage-limit queue gating and add a regression test for #21705. The provider-specific reset check and queue-resume behavior relate directly to the issue. No unrelated changes are evident in the reviewed diff.

Full details: Linked Issues check

Explanation

#21705 requires the A-selected message to remain queued after provider B succeeds, while preserving its saved account. usageLimitHoldsQueue filters by provider and uses the reset time. The regression test verifies that the queue stays held and that the message keeps its selection. However, #21705 also allows the user to explicitly retry or resume the work. The test confirms that queue.resume is rejected during the hold, and the shared gate applies the same hold to this explicit command. The available evidence does not establish another explicit retry path that satisfies this requirement.

Resolution

Allow an explicit retry or resume to release the usage-limit hold, while keeping automatic queue starts blocked until the limit no longer applies. Preserve the message’s saved provider selection.

Two cases this leaves stuck. Both checked with a runtime test against this diff.

1. A limit that has already reset keeps holding. With only A's runs read, A's latest run stays the usage-limit failure until A itself runs again. So once the user carries on with B, a message queued for A never starts, even after A's reset has passed. Example: A stops at 18:00 with a reset at 22:50 and a message still queued for A. The user continues on B. The next day the A message is still queued. The thread reads as idle, with no limit banner and no Resume, because the guard returns without setting queueHeld. It leaves the queue only if the user cancels it or sends on A themselves. On main it would have started and failed right after the first B turn.

Keeping the old rule and adding only the known-reset case avoids that:

1	const limited = usageLimitBlockedRun(
2	projection.runs.filter((run) => run.providerInstanceId === providerInstanceId),
3	projection.turnItems,
4	latestSession?.lastError ?? null,
5	);
6	if (limited === null) return false;
7	// Nothing ran after the limit: hold, as before.
8	if (latestExecutedRun(projection.runs)?.id === limited.id) return true;
9	// Another provider ran since: hold only while the reported reset is ahead.
10	const resetAt = latestRootProviderFailure(limited, projection.turnItems)?.resetAt;
11	return resetAt != null && Date.parse(resetAt) > DateTime.toEpochMillis(now);

Both callers pass yield* DateTime.now. A message held this way becomes eligible at the reset and starts with the next queue start, such as a run ending or a cancel. Nothing wakes the queue at resetAt itself, since resumeQueuedRuns has no production caller.

Commit with this change and its test: https://github.com/mkantautas/t3code/commit/6f5caae60974759600beab0465fa635cbb685a83. The test holds the A message after a completed B turn, refuses queue.resume, then advances the clock past the reset and expects the message to start on A. With this PR's version it fails at that last step (expected 'queued' to equal 'starting').

2. Delegated-completion wakes now block the whole queue. ProviderContinuationService queues them with no model, so each takes the thread's selection at queue time. queuedRunsInDeliveryOrder always puts them first, and reordering cannot move anything ahead of them. A wake queued while the thread was on A now holds every message behind it until A runs again, including prompts the user sent for B. With the change above, it holds them until A's reset. That probably wants its own fix, for example letting these wakes follow the current conversation as monitor updates do since #21314. This PR is what makes the case reachable.

Keep the queue held when the provider reports no reset time.

A usage-limit failure can carry resetAt: null. When provider B becomes the latest run, the provider-A-specific lookup still finds A’s limited run, but line 814 returns false for the unknown reset. The next automatic queue start can therefore retry A before recovery is known. The recovery worker and banner both treat an unknown reset as requiring manual retry.

Keep the queue held for an omitted or null reset time. Preserve release after a known reset has passed.

fix(server): an unknown usage-limit reset keeps the provider's queue held67d41c6

Mmaria12d ago

Note

Written by gpt-6.1-sol on behalf of Maria

Verified in a real dev environment

checked 67d41c66adf2ffce5de9d775e9c4328dce560d50 on this linux boat vm. this is partial runtime verification, not confirmation of the usage-limit fix.

installed and ran github/main (32ecd71726) in a separate worktree first. a real codex gpt-6.1-sol turn completed with MAIN_PROVIDER_OK.
stopped main, checked out the exact pr head, installed dependencies, and ran the dev server against isolated .t3 state. created a real git repo and project through the app cli. used repository playwright with /usr/bin/google-chrome.
on the pr, a real codex turn completed with PR_PROVIDER_OK. while another turn was running, t3 thread send reported the next message as queued. web composer steering reached the active provider. after it completed, the queued turn started automatically and returned QUEUED_TURN_OK.
added codex_2 through settings, selected it in the web composer, and completed SECOND_INSTANCE_OK in the same thread. persisted runs 1–3 retain codex; run 4 uses codex_2. both instances use the same proxy credentials.

29 checks report success on this head, with none failing or pending. no source changes, commits, pushes, or new test files. the evidence below shows neighboring behavior only. the 27-second recording was inspected, and uploaded playback and seeking passed. the animated image is a 17-second excerpt of that recording.

ordinary queue completed after active codex turn

real codex steering followed by automatic queue delivery

short runtime transcript

Not verified

the original bug could not be reproduced on main: no genuinely exhausted codex account was available, and the local proxy successfully completed the real turns. i did not inject quota errors, modify persisted events, use mocks, or burn quota to manufacture exhaustion.

therefore the changed hold after another instance succeeds, refusal of queue resume under that hold, known-reset expiry, and unknown-reset retention remain unverified end to end. they still need an exhausted instance a and an available instance b. this pass cannot certify the fix.

native desktop, ios/android, other providers, and remote/relay/tunnel connections were not exercised.

Takeover update

merged github/main into the branch with a merge commit (9370baf610). one conflict in Orchestrator.ts: main added queueTailModelSelection next to usageLimitHoldsQueue. kept both. no other source changes.
f42e7da93e: a resetAt that does not parse now keeps the hold, matching an unknown reset. added a row to the existing parameterized test. it fails without the guard.
vp run check:changed passed on blacksmith: format, lint, knip, typecheck (3 packages), tests (5 files, 144 tests). runtimeLayer.test.ts passed separately: 124 tests.

Review findings

coderabbit: an unparseable resetAt released the queue. fixed in f42e7da93e.
coderabbit: an unknown resetAt released the queue. fixed in 67d41c66ad, where resetAt == null keeps the hold.
mkantautas point 1: a reset that has passed kept holding. the current code holds only while nothing ran after the limit or the known reset is still ahead. this matches the suggested rule.
mkantautas point 2: delegated-completion wakes queued on the limited provider hold the queue behind them. that needs its own fix. it is out of scope here.
coderabbit linked-issue check: "explicit queue.resume should override the hold". main already refuses queue.resume under a usage-limit hold. this PR keeps that rule, so the suggestion is out of scope.

Not verified

the hold after another provider succeeds is verified only by runtimeLayer.test.ts. it was not exercised end to end. that needs a genuinely exhausted provider instance.

Treat an unparseable resetAt as an unknown reset.

The comment above the function says "an unknown reset never does" lift the hold. A resetAt string that Date.parse cannot parse returns NaN. NaN > now is false, so the hold lifts immediately once another provider has run. Other code in this file guards with Number.isFinite(Date.parse(...)) (see holdStoppedThread). Apply the same guard here.

Proposed fix

diff

1	- return resetAt == null \|\| Date.parse(resetAt) > DateTime.toEpochMillis(now);
2	+ if (resetAt == null) return true;
3	+ const resetMs = Date.parse(resetAt);
4	+ return !Number.isFinite(resetMs) \|\| resetMs > DateTime.toEpochMillis(now);

Add a resetAt value that is not a date to the existing parameterized test if you want this case covered.

Evidence

Real web client and server, fresh isolated databases, Chromium at 1280×800, light theme. Synthetic provider responses entered through the real adapter; no database rows were inserted.

Start Account A and queue another A message while it runs.
Fail A with a usage limit and future reset; confirm the message waits.
Select B, send immediately, and let B succeed.
After the reported reset passes, complete another B turn.

Before	After
c82e1ba515	e0382359a3
Before: B success consumes A's queued message and returns to Limited	After: B succeeds while A's message stays queued
Before recording	After recording, including reset recovery

Head preserves the saved account: after reset and another successful B turn, the waiting message starts on A and completes.

After: queued message completes on Account A after reset

Not shown:

Actual subscription exhaustion and renewal were not exercised because first-party OAuth accounts are unavailable; usage-limit responses were synthetic.
Explicit queue resume and Send now overrides were not exercised; this proof covers automatic queue holding and release after reset.
