Addressed the one review item; it was correct. waitsOnPendingRequest counted every pending runtime request, including user_input requests answered by a message (async Codex questions, and open questions converted to 'message' by ProviderRuntimeRecoveryService after a restart). These have no provider callback for a steer to abort. They stay pending across turns, and ProjectionStore, EventSink and the Orchestrator settle check all treat them as non-blocking. So one ignored question turned every later steer and promote-to-steer on the thread into a queue, which origin/main does not do. The guard now counts only requests that are pending and whose responseCapability.type is not 'message', matching the existing blocking definition. The unit test now seeds blocking requests and adds a pending 'message' request that must still steer; it fails on the previous guard (2 of 15) and passes now. The integration test seeds a blocking ('live') request instead of a 'message' one. Everything else the fix does is unchanged: steers queue behind a blocking request, promoted messages go to the front, and explicit restart still interrupts, including for /goal. The new commit's message ends with a Co-Authored-By line naming the model, which the privacy rule forbids; it could not be removed without a force-push, so it needs a reworded squash commit at merge.

Fixes #26841

Supersedes #26842. The change is @immakermatty's; their commits are kept.

Reproduction on main

These steps were read, not executed: In a Claude thread, select Steer as the follow-up behavior and ask the agent to use AskUserQuestion. Leave the question unanswered, then send another message from the composer. On main the steer can cancel the question; with this change the message queues and the question remains pending. Repeat by promoting a queued message, sending t3_thread_send with mode auto from another thread, and triggering a tool approval instead of a question. Answer the request and let the active turn finish to verify queued delivery.

Evidence

Environment: real web app, Chromium on Linux, 1280 × 800, light theme; separate fresh databases, synthetic CLI/MCP seed data, Replay (dev), supervised mode.

Steps on both commits: leave a question or approval pending, queue two follow-ups, then click Send now on the second. Base shows Superseded attempt / Cut off by a steer and starts a replacement request. Head preserves the original request and moves the selected message first.

	Before	After
Commit	fa8949a28c	a5649bac5f
Pending question	Before recording	After recording
Pending approval	Before recording	After recording

Head continuation: question answers and queued delivery; approval answer and promoted delivery.

Seed script, MCP driver, matched-thread seed, auto-send driver, driver instructions.

Attempted scenario could not execute the composer reproduction and is not proof. Supporting recordings and redacted logs.

Proven scope: queued-message promotion through the shared server guard using replayed questions and approvals. Native Claude composer and cross-thread auto-steering remain unverified.

Not shown:

• Native Claude AskUserQuestion and priority-now callback cancellation were not run; replay exercises ACP interrupt/restart steering through the shared server guard.
• A separate composer follow-up during a pending question was not reproduced: the replay question is choice-only and disables the composer. Evidence exercises queued-message promotion instead.
• Auto send from a real second agent thread remains unverified. An external MCP mode:auto send queued on both replay builds, so it did not reproduce Claude's automatic active-steering path.
• Nonblocking questions answered by later messages remaining steerable were not covered by the replay fixtures.

Tests

vp test run src/orchestration-v2/CommandPolicy.test.ts src/orchestration-v2/SteeringCompletion.integration.test.ts (apps/server): 79/79 pass. With the previous CommandPolicy.ts restored, CommandPolicy.test.ts fails 2/15 (the new non-blocking case), confirming the test catches the regression. vp run check:changed: format, lint, knip, graphql, typecheck (3 packages) and test (6 files) all pass.

Not in this change

• Not verified: how a promoted message is ordered against deferred steers (steerWhenReadyRunId) already waiting for the same run when a request becomes pending; left as main has it.
• Orchestrator.ts:4105's settle check also treats non-user_input 'message' requests as blocking (kind !== 'user_input' ||). The steer guard uses the simpler ProjectionStore/EventSink definition, and the two were not aligned.

Walkthrough

Steering now queues while a pending runtime request requires a response. Queued-message promotion preserves that request, while goal restart can still interrupt the run and cancel it. The composer guide documents the queue behavior.

Changes: Pending request dispatch

Layer / File(s)	Summary
Pending-request dispatch policy apps/server/src/orchestration-v2/CommandPolicy.ts, apps/server/src/orchestration-v2/CommandPolicy.test.ts	Dispatch policy queues steering when a pending runtime request has a non-message response capability. Tests cover pending requests, resolved requests, and message-response requests.
Orchestration and route validation apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/SteeringCompletion.integration.test.ts, docs/user/composer.md	Orchestration preserves pending requests during steering and queued-message promotion. Goal restart can still interrupt and cancel the request. Integration tests cover the routes, and the composer guide describes the behavior.

Merge Risk: Moderate · up to a5649

Steering now queues behind pending questions and approvals, but providers that rely on interrupt/restart can still cancel a pending question on an automatic send. Separately, multiple queued steers can be delivered in reversed order once a blocking request is pending. Both should be fixed before merge unless explicitly accepted.

Full details: Title check

Explanation

The title names the main change: steering no longer cancels a pending question or approval. The raw summary and objectives confirm the change adds a guard so that pending blocking runtime requests cause steers to queue. The title follows the conventional commit format from the template and is specific enough for a teammate scanning history.

Full details: Linked Issues check

Explanation

Requirements from #26841: a pending question or approval must stay open, and a new message must queue behind the active turn. At head, CommandPolicy.ts adds waitsOnPendingRequest, which returns true for a pending runtime request whose responseCapability.type is not "message". resolveMessageDispatchIntent maps a resolved steer_active intent to queue_after_active when this returns true. This applies to all steer paths named in the issue (composer steer, deliveryIntent "auto"/"steer", promote-to-steer, sendToThread). Orchestrator.ts applies the same guard to goal stops and to queued-message promotion, where the promoted run is placed first and waits. Explicit restart (restart_active) still interrupts, including for goal commands. The requirement is met by code evidence. The unit and integration tests are described in the PR and were not re-run here. Non-blocking 'message' requests are excluded by design, which the issue does not address directly; the PR justifies this because those requests have no provider callback for a steer to abort. The unaligned condition at Orchestrator.ts:4105 is outside the issue's stated requirements.

Full details: Out of Scope Changes check

Explanation

All changed areas relate to #26841. CommandPolicy.ts adds the guard. Orchestrator.ts applies it at the steer, goal, and promotion paths named in the issue. The tests cover the guard and the steer/promote routes. docs/user/composer.md documents the new queuing behavior. No unrelated change is evident from the summary and the inspected diff. The commit message Co-Authored-By issue is a repository policy matter, not a code scope change, and does not affect this assessment.

Full details: Description check

Explanation

The description states the problem, the change, the linked issue (#26841), the superseded PR, and extensive verification: unit and integration test results, a regression check, and check:changed results. It also records reproduction steps, evidence links, and unverified areas. Every template section is filled in. The author also discloses a commit-message compliance problem and an attribution note. The description is thorough and specific. Its length and the number of links exceed the template's needs, but no required section is missing.

Protect automatically selected restarts from pending requests.

If active steering and queued messages are unsupported, but interrupt/restart steering is supported, resolveDeliveryIntent returns restart_active for "auto" at Lines 202-204. Line 112 then returns before this guard runs. Orchestrator.ts, Lines 6966-6994, dispatches that message with forceRestart: true, despite the pending live request.

Apply the pending-request protection to automatically selected restarts too. Keep the bypass for an explicitly requested restart.

Major · Data Integrity & Integration · Heavy lift

Keep deferred steers in their original order when a request is pending.

When a blocking request is pending, deliverDeferredSteers dispatches each queued steer in queue order (Orchestrator.ts:15230-15248). Each dispatch takes the pending branch, which sets its run to queuePosition: 1 (Orchestrator.ts:10900). stopRunForQueuedCommand then renumbers the other queued runs to index + 2 (Orchestrator.ts:13127-13139).

For deferred steers A then B, the first dispatch sets A to position 1. The second dispatch sets B to position 1 and moves A to position 2. queuedRunsInDeliveryOrder sorts by queuePosition (QueuedRunOrder.ts:28), so B runs before A. The send order is reversed.

Preserve the relative order of the deferred steers in the pending branch. Do not promote each steer to position 1 independently.
