fix(server): queue explicit steer between provider turns - #23559
An explicit Steer sent while a run is starting or between provider turns fails with “No running provider turn found” and leaves the follow-up undelivered. Reproduced on current main by starting a real Claude run and immediately dispatching an explicit Steer through the authenticated web connection.
Change
Apply the existing provider-turn gap check before resolving explicit Steer. Follow-ups in those gaps use the durable queue; steering a running provider turn and explicit Restart retain their existing behavior.
Red: six policy cases failed on main because explicit Steer returned steer_active rather than queue_after_active.
Green: vp test run apps/server/src/orchestration-v2/CommandPolicy.test.ts apps/server/src/orchestration-v2/runtimeLayer.test.ts apps/server/src/orchestration-v2/SteeringCompletion.integration.test.ts — 106 tests passed across three files on the final head.
Scoped lint and server typechecking passed. Two independent reviews returned MERGE.
Runtime: Linux web dev server, Chrome headless, Claude Code 2.1.303 / claude-opus-5-5. Before, explicit Steer was rejected; after, both requests succeeded, the follow-up queued, and Claude consumed it and returned the expected marker. Both runs completed.
Before: 8d3b061121; after: 2d0622b17b. Server-only change; no render paths changed and the capture matrix is empty. Tests cover preparing/starting, absent/pending/completed provider turns, and a running turn from a previous attempt. Controls preserve automatic delivery, Restart, and steering a matching running turn.
The reporter’s native Windows surface was not run; the reproduced failure and fix are in shared server policy. Runtime provider verification covers Claude; other adapters are covered by the shared policy tests and review.
Models: Claude Opus 5.5 and GPT-6.1-Sol. Harnesses: Claude Code and Codex through T3 Code.
Proof audit
Independent proof audit: SUFFICIENT (fixture matrix · audit pass 2). Runtime transcripts cover explicit Steer in the early gap (rows 1–3), no active run (row 12), and the new regression control: explicit Steer into a running provider turn still steers the live run on both builds (row 7: before · after). Driver: apps/server/scripts/verify-steer-running-turn.ts (c990ba1b46).
Verification log
Audit pass 1 (claude-opus-5-5): SUFFICIENT; row 7, explicit Steer while the active attempt's provider turn is running, flagged as the uncovered runtime control.
New captures (real server, isolated home, real Claude turns on claude-sonnet-5-5, no tools), same driver for before 8d3b061121 and after 2d0622b17b:
Row 7: the provider turn was running at dispatch. Steer was accepted and delivered into run 1 (inputIntent: steer), with one run in total and ROW7_STEERED returned. Identical on both builds.
Row 9: explicit Restart during a running turn was rejected on both builds with "Claude cannot redirect an active run". That is the Claude capability check, which this PR does not change (before · after).
Audit pass 2 (claude-opus-5-5): SUFFICIENT. All SHAs match, and c990ba1 changes only the driver script. The auditor rebuilt row 7 from the committed script and got a matching result (rebuild).
Unit-test-only rows: 4, 6, and 8 (a pending provider turn or a previous attempt's running turn needs synthetic projection state or narrow races), 5 (completed turn while the run is still active; the timing window is tight), and 10–11 (auto-delivery controls, path unchanged). Rows 1–3 share one transcript that does not record which gap state the run was in; each row has its own unit test.
Unverified: none. Not covered: a unit test for Restart during a running turn (this gap predates the PR), and providers other than Claude at runtime.
Model/harness: Claude Opus 5.5 (lead, auditors, capturer) through Claude Code in T3 Code; captures ran Claude Sonnet 5.5 as the provider.
Macroscope's review found this PR requires human approval — The server policy change is a focused bug fix, but the PR adds a live verifier with file-level static-analysis suppressions and unresolved paths that can report success without proving delivery or leave a detached server running. These review-sensitive issues require human assessment before approval.

Walkthrough
Explicit steering now queues after an active run when the run is preparing or starting, or when its active attempt has no running provider turn. Restart delivery remains unchanged. Tests and a host-side verifier cover delivery behavior.
Changes: Steer delivery policy
Layer / File(s)
Summary
Steer delivery during active-run gaps apps/server/src/orchestration-v2/CommandPolicy.ts, apps/server/src/orchestration-v2/CommandPolicy.test.ts
The policy checks for an active-run gap before selecting steer_active. In preparing or starting states, or when the active attempt has no running provider turn, explicit steering resolves to queue_after_active. Tests cover these cases and confirm that restart still resolves to restart_active.
The verifier starts a server in an isolated home, dispatches a second message after observing a running provider turn, and records the dispatch result, final projection, and event timeline. It writes a failed result and exits with a nonzero code on verification errors, then stops the server. Knip includes the verifier script as an entry point.
pingdotgg/t3code#23403: Explicit steering can now enter the durable queue when no provider turn is running. The PR does not change queue visibility.
pingdotgg/t3code#26546: The PR routes explicit steering through the queued state described in the issue. It does not add the missing UI label or Send now control.

Explanation
Issue #23271 requires explicit Steer to queue when the active run is preparing or starting, or when its active attempt has no running provider turn. CommandPolicy.ts checks those gaps before resolving steer and returns queue_after_active. The check includes absent, pending, completed, and previous-attempt turns. restart remains resolved before the gap check. CommandPolicy.test.ts covers all required gap states, explicit Steer, Restart, and steering a running turn. The reported 106-test run supports the implementation.

Spawns an isolated server from any checkout, starts a real Claude turn, and
sends an explicit Steer or Restart once the active attempt's provider turn is
running. The JSON transcript records the observed state at dispatch, where the
message landed, and every run, so two builds can be compared directly.

Make delivery part of the verifier’s success condition.
The script documents that Steer or Restart must reach the active run. The current completion condition only checks that a dispatch was attempted and that all runs became terminal. A rejected dispatch is converted to { ok: false, error }, so it can still produce status: "finished" and exit zero. The final code also records the run association without validating it.
‼️IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Wrap the transcript write in try/finally so stopServer() always runs.
The finally block runs git(...), uname, and writeFileSync before it calls stopServer(). Each of these calls can throw:
git rev-parse throws when --server-root is not a git checkout.
execFileSync("uname") throws when uname is missing.
writeFileSync throws when the --out directory does not exist.
When one of them throws, stopServer() never runs. The server was started with detached: true and keeps running. It holds the port and the isolated home directory, so the next run can fail on the port or the home directory. The new exception also replaces the original failure, and no transcript is written.
Run stopServer() in a nested finally. Also make the environment probes non-fatal, so a failed probe does not discard the result.

Preserve the Stop guard for explicit gap steering.
When an active run has no running provider turn, explicit steer now resolves to queue_after_active and bypasses dispatchSteerIntoRun’s stopReachedRun check. The queue path sets Stop-held runs to queueHeld: false for client messages, so this steer can resume work after Stop.
Before releasing held runs, reject an explicit steer when its active run satisfies stopReachedRun, using the existing stopping error. Add a regression test for an active run with a failed provider turn, a recorded Stop, and an explicit steer.
SteeringCompletion.integration.test.ts covers a failed continuation, but its steer is dispatched while the provider turn is still running and it does not issue Stop. It does not cover this combined state.

Messages sent while the agent was busy each got their own turn, and steers
that missed the end of a turn were re-sent one turn each. Now, like Claude
Code, everything that piles up goes to the agent together.
- When a turn ends, compatible queued messages start as one turn (adapted
from pingdotgg#26072). Notifications, slash commands, scheduled
tasks and messages for another model still get their own turn.
- Just before a provider turn starts, queued messages fold into it, so
several steers that miss a turn land in one follow-up turn.
- Missed steers re-send as "auto", joining a running follow-up. Explicit
steers between provider turns queue instead of failing (from pingdotgg#23559).
- Settings > Chat > "Send queued messages together", on by default.
- Composer: with Enter to send, Enter continues a bullet list; Enter on an
empty bullet removes it and sends.
- Shorter Meeseeks status labels so the sidebar timer stays visible.

Problem
An explicit Steer sent while a run is starting or between provider turns fails with “No running provider turn found” and leaves the follow-up undelivered. Reproduced on current main by starting a real Claude run and immediately dispatching an explicit Steer through the authenticated web connection.
Change
Apply the existing provider-turn gap check before resolving explicit Steer. Follow-ups in those gaps use the durable queue; steering a running provider turn and explicit Restart retain their existing behavior.
