A message whose acknowledgement never arrives can leave the composer busy indefinitely even while the socket answers heartbeats. Pressing Enter on a second draft during that send is ignored; the draft remains visible but is not submitted.
Bound message-dispatch and first-message launch acknowledgements to two minutes. Report that an unanswered message may still arrive, without automatically retrying it.
Remember one pending submission in the web composer and send the unchanged draft after its preceding send succeeds. Keep the draft and show a notice if that send fails or a new approval or question appears. Scope completion to the originating thread and preserve content typed before the earlier draft clears.
The deadline covers message and launch acknowledgements, not attachment uploads or earlier settings/projection requests. Existing slow-request reporting remains in use. Native mobile receives the shared deadline; deferred composer submission uses the web path shared with desktop.

The evidence below is from its reviewed implementation parent; the final merge added upstream changes and did not alter the bug-fix diff.

Full capture report and request logs, fixture matrix, fault-injection driver, seeding and protocol.
Linux fs-34, real isolated web app and server, Chromium collaborative preview, DPR 2, CSS 1440×900 or 390×844 as labeled. Narrow captures cover responsive web. Codex/GPT-6-Astra, harmless literal-answer prompts, no tools. Before is fef851bee0; after is 887f485adf.
For delivery, press Enter on FIRST, delay its selected request 10 seconds, type SECOND and press Enter during the delay. The desktop case also repeats Enter. Before leaves SECOND unsent; after sends it exactly once as queue_after_active. For timeout, suppress only the selected message request, keep heartbeats flowing, submit SECOND during the wait, and record beyond 125 seconds. Before remains busy; after shows the uncertain-delivery error and unsent notice, preserves SECOND, releases the composer and does not retry. Outgoing suppression proves the client-visible no-answer behavior; the focused tests separately prove a server-received request that never answers. The reporter's heavy host load was not recreated.

What else changed between captures: conversation history grew, timestamps/sidebar recency advanced, and historical/current git summaries differed as commits were switched. These backgrounds were not frozen or restored to identical database snapshots; the comparison does not establish pixel isolation or absence of other visual changes. Invalid footage from a stale Vite transform was excluded, and the full runner was restarted before valid fixed-head recordings.
Unverified matrix rows: editing/clearing/resubmission; simultaneous cross-thread navigation and stale completion; restoration of the original draft into an empty composer and manual recovery; arrival of an approval or question; attachments/model bookkeeping; special callers and blockers; late commit/reconnect behavior; relay/tunnel and other providers. Native iOS and Electron runtime were not exercised. The shared deadline and mobile restore classification were source-reviewed, while these browser recordings cover local web only. Two amplified/threshold difference images per pair and independent pixel reproduction are not complete.
Proof audit: PASS2 report inspected all nine valid recordings and supports the core outcomes, but returned INSUFFICIENT for the uncovered rows above, repeated-Enter input-event provenance and pixel isolation. Those verification items remain pending; this is not a complete evidence-matrix pass.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — The PR changes existing message-send behavior across the web and shared client runtime by adding deferred submission coordination and a two-minute acknowledgement deadline. The hardcoded deadline is a product-wide default and the async state machine has a broad enough runtime surface to merit human review.
You can add or adjust custom eligibility rules. Learn more.
The PR adds queued follow-up submissions to the composer and a two-minute timeout for unanswered message dispatches and thread launches. It also adds tests for queue resolution, draft changes, and unanswered requests.

Explanation
The title "fix(web): stalled sends fail and preserve the next message" matches the main change. The PR makes unanswered message-dispatch and first-message launch acknowledgements fail after two minutes with an uncertain-delivery error. It also makes the web composer keep and send one pending follow-up submission after the preceding send succeeds. The title names both parts, uses a conventional commit prefix, and stays under 60 characters.
Explanation
The description follows the template. It has Problem, Change, Scope and approval, and Verification sections. The Problem section states the stalled composer and the ignored Enter press. The Change section covers the two-minute deadline, the deferred submission, and the draft preservation. Scope links issue #23661 and notes the triage source. Verification lists the focused test command and results, typecheck and lint status, and a browser pass with recordings. It also names unverified rows and the pending proof audit. Some points are weak. The Scope section gives no maintainer approval comment, and the evidence section is long and partly unverified. The core template requirements are still met.
Explanation
The reviewed changes stay within issue #23661. The client-runtime timeout and error support the stalled-send behavior. The web composer queue, draft-preservation logic, thread and generation checks, notices, and focused tests support deferred submission and loss prevention. No unrelated change is established by the available whole-PR evidence.
Explanation
The changes satisfy two concrete requirements from issue #23661: commands.ts applies a two-minute deadline to message dispatch and first-message launch acknowledgements, and useComposerSend.ts retains one unchanged follow-up draft and settles it by thread and send generation. The added tests cover timeout behavior and queued-submit cases. The issue also requires reporting a stalled command pipeline while the socket remains healthy. The reviewed changes report only an unanswered individual message or launch through MessageDispatchUnansweredError; they do not add a command-pipeline stall report or longest-outstanding-command tracking.
Resolution
Implement the command-pipeline stall reporting required by #23661. It must detect and report an outstanding command pipeline independently of socket heartbeat activity, or provide equivalent reviewed behavior that identifies the stalled pipeline rather than only timing out the individual message.

External image Minor · Functional Correctness · Quick win
A new Enter is silently discarded when the queued submit is already ready.
When queued.ready is true, queueComposerSubmitBehind returns the existing queued object. That object includes draft, dispatchMode, and submissionIntent. The ...behind spread on Line 1500 comes last and overwrites the fields captured from the new Enter.
A ready submit can stay blocked for a while. For example, queuedSubmitBlocked stays true while isSendBusy is true.
Sequence:
onSend re-queues the old draft B instead of B2.resolveQueuedComposerSubmit sees draftUnchanged: false and returns "drop". The drop is silent.B2 stays in the composer, is never sent, and shows no notice. The not-ready case does not have this problem, because there the new Enter replaces the queued draft.
Put the spread first so the latest Enter wins and keeps ready.
