Background-task wakes could start a completed turn after a usage-limit failure, hiding the failure from automatic recovery and clearing its snooze. Messages dispatched as queue_after_active now wait behind that failure during the reset window and preserve snoozed or settled state. After a known reset, new work starts when no eligible armed auto-resume remains pending. Automatic recovery and intentional immediate resumes still start ahead of held work.
The same usage-limit check now serves dispatch, queue startup, and queue resume. This applies to composer queue sends, MCP queue sends, and delegated/background deliveries through the shared server orchestrator; no client or wire-contract changes are needed.
Missing or malformed reset timestamps keep the usage-limit queue protection. Already-queued work keeps the existing queue gates; this changes dispatch of new arrivals. A wake held during the window without auto-resume still needs a later arrival or manual continuation. Bound scheduled tasks can accumulate queued runs during the window; those runs drain after a successful continuation.
Maintainer takeover of #20804, credited to @dev-ankit for identifying and fixing the recovery failure. Original commits are preserved; current main was merged rather than rebasing the contributor branch. The batch authorizes preparation only. Macroscope's separate human approval gate for usage-limit runtime behavior remains outstanding; this PR has not been merged.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — This production change alters whether queued messages start, how settled or snoozed threads recover, and when usage-limited work resumes. Because it directly affects plan usage-limit and entitlement behavior, its runtime impact warrants human review despite the focused scope and regression tests.

The orchestrator now identifies provider-specific usage-limit blockers during dispatch. It retains queued work during qualifying reset or auto-resume windows and preserves snoozed or settled state while a blocker remains. Tests cover same-provider and other-provider wakes, reset timing, snooze, and settlement.

7078cBackground wakes no longer block usage-limit recovery. One minor gap remains: after the reset time passes, an explicit Resume of the queue can still be rejected, and a new message can start ahead of earlier queued work. This is a small, bounded inconsistency to follow up on.

Explanation
The description provides detailed problem, change, scope, approval context, verification results, limitations, and linked issues. It omits the explicit Problem and Change headings, but the required information is present. Separate human approval remains outstanding, as clearly stated.
Explanation
The changes address [#32286] and [#16815]. Orchestrator.ts holds same-provider queue_after_active arrivals during an active usage-limit reset window. It preserves pending auto-resume, snooze, and settlement state. After the reset, it releases new work when no eligible auto-resume remains pending. The shared dispatch path covers background and delegated deliveries. runtimeLayer.test.ts covers snoozed recovery, settled recovery, provider differences, expired and unknown reset times, and post-reset dispatch.
Explanation
The changes are limited to usage-limit queue handling in apps/server/src/orchestration-v2/Orchestrator.ts and focused regression tests in apps/server/src/orchestration-v2/runtimeLayer.test.ts. These changes directly support [#32286] and [#16815]. No unrelated product behavior, client changes, or wire-contract changes are demonstrated.

Taking over this one as maintainer for batch usage-billing-05. I will preserve the original commits, rebuild and verify the focused usage-limit queueing behavior, and push additive fixes here. Thanks @dev-ankit for identifying the background-wake recovery failure. This batch will not merge the PR.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use one reset-expiry rule for dispatch, queue start, and queue.resume.
The reset-expiry release exists only in dispatchMessage, at Lines 4919-4928. usageLimitHoldingRun and usageLimitHoldsQueue do not check resetAt. The two other gates still call usageLimitHoldsQueue:
startNextQueuedRun at Line 1393.queue.resume handler.After a known reset, both gates still hold the queue. The PR describes one usage-limit check for dispatch, queue startup, and queue resume. This code does not implement that.
Here is how it fails when auto-resume is not armed:
limitedRun.queue.resume rejects it with "Continue the limited thread before resuming its queue."limitedRun and starts at once. It runs ahead of the earlier queued wake.The result is that queued work runs out of order, and the explicit Resume action fails where a new message succeeds.
Move the reset-expiry and autoResumePending logic into one helper that takes now. Then call that helper from all three gates.
| 1 | function activeUsageLimitHold( |
| 2 | projection: Pick< |
| 3 | OrchestrationV2ThreadProjection, |
| 4 | "thread" | "runs" | "turnItems" | "providerSessions" | "runtimeRequests" |

| 11 | const failure = latestRootProviderFailure(run, projection.turnItems); |
| 12 | const resetMs = Date.parse(failure?.resetAt ?? ""); |
| 13 | if (!Number.isFinite(resetMs) || resetMs > nowMs) return run; |
| 14 | return autoResumePending(projection, run, failure, resetMs) ? run : null; |
| 15 | } |
startNextQueuedRun and queue.resume must load runtimeRequests for this helper.
