feat(server): option to start queued messages together as one turn - #26072
When several messages are queued during a turn, each one starts its own turn. The agent re-plans after every message and can act on the first before it sees a later one that changes the picture. This is proposal 2 ("batched queue mode") in #15815.
Change
A server setting, Settings > Chat > Send queued messages together, next to Follow-up behavior and off by default. When it is on and a turn ends:
Every queued message that can share a turn starts together as one turn. The provider gets one message that opens with "These N messages were queued separately while you were working. They are listed in the order they were sent, with their senders. Handle each one accordingly.", followed by each message with its number and sender.
The timeline still shows each message on its own, all under that one turn.
Notifications, delegated task completions, scheduled tasks, /compact, /goal, and messages for a different provider or model still get their own turn. Batching stops at the first of these, which then runs next.
Sending one queued message now from the queue list still sends only that one. Steer is unchanged. At most 20 messages go into one turn.
A completed turn also releases held messages so they go out in the batch. An interrupted turn releases nothing.
The fold reuses the promote-to-steer pattern: folded runs are cancelled, and their messages and turn items move into the starting run.
Scope and approval
This is a new behavior behind a setting, so it needs maintainer approval. No maintainer has approved it yet. The direction is proposed in #15815, and this PR is there so the discussion can look at working code. Happy to close it or change scope based on that discussion.
Verification
Ran on a Linux server with the same change applied to our fork. I started a turn running a 2-minute command and queued three notes during it. With Claude Haiku 5.5 and with Codex on GPT-6 Astra, all three ran as one next turn, and the one reply answered each note. The wrapper text appeared in both providers' session logs. With the setting off, the same script gave three turns.
Existing tests near the change pass: runtimeLayer.test.ts, ThreadStop.test.ts and ProviderTurnStartService.test.ts (164 tests), plus the settings, contracts and client-runtime tests (716 tests). vp run check:changed passes format, lint, knip and typecheck. Its full test step stopped on an unhandled vi.mock error in a browser test unrelated to these files.
I did not add focused tests for the batching itself yet, and I'd like direction on where they belong.
Not checked: attachments on folded messages, a full batch of 20, and mobile, which has no row for this server setting. No screenshot of the new settings row is attached yet.

🟠 Highorchestration-v2/Orchestrator.ts:1485
When thread.stop runs after a completion is stored but before queue promotion, this block clears the queued runs’ queueHeld flags and starts them anyway if batchQueuedMessages is enabled, overriding the later Stop. The completed run’s status remains completed, so check that the completion still owns the queue—including the stop marker—before releasing the holds.

Fixed in 1765118. The batch-release path now checks the stop marker on the completed run before releasing held queued runs, so a Stop that lands after completion cannot start the queue. It also avoids reading the projection when batching is disabled. Focused server checks passed: typecheck and 164 existing orchestration/provider tests.

Restarting a queued turn resends its original prompt after the new steering message, so the provider receives stale instructions as if they were newer queued messages. Because restart preserves the run ID and the old item still has inputIntent: "queued_turn", this filter includes it; restrict folding to the current execution node/attempt or explicitly recorded batch members.

False positive on the current branch. Restart continuations create a new run ID with restartContinuationOfRunId set, and batchableMessage already excludes such runs. foldedQueuedTurnItems only selects queued-turn items with the current run ID, so the prior prompt cannot be folded into the continuation. No code change was needed.
Macroscope's review found this PR approvable — Adds an off-by-default option to combine compatible queued messages into one agent turn. The reported Stop, restart-prompt and settings-navigation issues remain subject to the separate blocking correctness gate.

The batchQueuedMessages setting defaults to false and is included in shared settings. The settings UI supports changing, searching for, and resetting the setting. The documentation describes the batching behavior.
Queued-run selection and transfer apps/server/src/orchestration-v2/QueuedRunBatch.ts, apps/server/src/orchestration-v2/Orchestrator.ts
The batch helper selects eligible queued runs and creates events to transfer their messages and turn items. When batching is enabled and a completed run meets the stated conditions, the orchestrator releases held runs. It adds transfer events when it starts an automatically selected run.
The provider turn service folds queued user items into the prompt and combines their attachments for handoff budgeting and root-run startup. A test verifies folding by node and ordinal.

queuedRunBatch, queuedRunBatchEvents, foldedQueuedTurnItems, and batchedProviderText in apps/server/src/orchestration-v2/QueuedRunBatch.ts are pure functions with no test file that names them. Add direct tests for:
the 20-message cap (the first run plus 19 members);
a stop at the first incompatible provider instance, model selection, workspace-preparation type, or excluded message;
member events for each included run: the cancelled run, its active attempt and root node, and the transferred message and turn item;
the single-part case in batchedProviderText, which returns the text unchanged.
Test scope
Direct helper tests give fast, deterministic checks of the selection and formatting rules, separate from orchestrator wiring.

Fold only queued turn items on the current user input node when preparing a provider turn after interrupt/restart.
Co-Authored-By: GPT-6.1 Sol via Codex
Found a bug in this PR's batching while testing. When a turn that started from a batch of queued messages is interrupted and restarted (a queued message promoted on a provider that restarts instead of steering), the restarted prompt included the batch's earlier messages again, next to the new one. foldedQueuedTurnItems picked every queued item on the run instead of the items for the current input.
Fixed in b3b9ae8: the folded items are now selected by the current input. I reproduced it with Codex by forcing the restart path: before the fix the provider got the new message plus the two earlier ones, after it only the new one. A normal batch at turn end still carries all its messages.
8a2691c adds a focused test in QueuedRunOrder.test.ts, "folds a completed batch but excludes its messages after the turn restarts on a new input node". It fails without the fix and passes with it, and vp run check:changed passes.
The current array matches ordinal order, so the test passes if foldedQueuedTurnItems returns projection-array order. Use [third, first, second] and keep the expected result [second, third].

@coderabbitai Good catch on the fixture order, thanks. Done in b356b80: the batch is now [third, first, second] with the expected result still [second, third]. With the toSorted call removed from foldedQueuedTurnItems the test now fails, and it passes with it.
For best results, initiate chat on the files or code changes.
@aneym Thanks for the update. The shuffled fixture [third, first, second] with expected output [second, third] checks ordering rather than preserving input order. Your reported failure without toSorted confirms that the test detects the missing sort.

thanks for trying to help improve t3 code. if you think this closure was a mistake, please open a fresh pr addressing the requirement above, and link back to this one.
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.
