Fixes #15611. Also reported in #15717. Replaces #15612.

Problem and change

A queued message can send its original text while you are editing it. This PR holds that message until Save or Cancel. Save sends the revised text; Cancel keeps the original. The active response continues normally.

The hold preserves queue order and independent Stop, restart, and failure pauses. Web, desktop, and mobile share the commands. Editors track ownership so a stale client cannot overwrite another edit, and unsaved drafts remain recoverable.

Original recordings

These show the original bug and earlier fix, not verification of the November 1 integration.

Andrew tested this earlier Android build and reported that it worked. A separate before-fix Android recording and current-build close/reopen verification are still outstanding.

November 1 integration

Updated against main at 23075af981, preserving the contributor history. Resolved the web, mobile, shared-client, and server conflicts. Reused main's sequence tracking and kept its attachment-only prompt handling, child-agent approval UI, and unattended queue recovery.

Current local verification:

  • 220 focused tests passed: web queue/editor/draft tests (26), mobile draft/edit/permission tests (99), server edit holds (9), and shared commands/ownership/execution tests (86).
  • 21 React compiler cases passed across the changed web and mobile files.
  • Shared-client, web, mobile, and server typechecks passed. Changed-source lint and formatting passed.
  • check:changed passed dependency-patch, formatting, both unused-code, and GraphQL checks. Its first typecheck found automatic-merge duplicates; those were corrected and the affected typechecks rerun successfully. The broad test step was interrupted; the focused results above are separate runs, not a claim that the entire command passed.

Current-head CI must still complete. No new APK or manual native runtime verification is claimed. T3's Browser and Device verification tools are unavailable in this session.

Scope and attribution

This retains Julius's composer-chat-19 rebuild and the existing contributor history. Credit to @Andrew-Forster for the original implementation, @GLDRoger for failure-pause and reordered-queue analysis, and @juliusmarminge for the ownership and recovery rebuild.

The server advertises an additive capability so older hosts remain connectable, but those hosts do not provide the durable hold. Attachment restoration and recovery are part of preserving the edited message, not separate features.

Earlier rebuild verification and evidence

Previous rebuild verification

  • Before implementation, eight server hold cases and two client ownership/presentation regressions failed against the base. The rebuilt head passes 716 tests in 15 focused suites. The first final run passed 714 cases and timed out on two workspace-launch tests during severe machine contention; both passed in a focused rerun. Coverage includes the existing runtimeLayer, ProjectionStore, commands, threads-sync, threadExecution, web queuedMessageEdit/composerDraftStore/composerContextRecords, native queued-run-edit/use-composer-drafts/attachmentUpload/composerContext, and ServerEnvironment/ThreadLaunchService/ThreadStop suites.
  • Scoped web, mobile, server, client-runtime, contracts and shared typechecks passed after integration; affected scopes were rechecked after the attachment fix. Changed-source lint has no errors. No repository-wide checks were run locally.
  • Independent full-diff reviews: Claude Opus 5.5 and GPT-6 Sol. Rounds 1–4 found ownership, compatibility, Resume, stale-draft, attachment integrity and asynchronous cleanup issues; those were fixed. Round 5: both reviewers found no code blockers. Two optional recovery UX nits remain: undoing a removal can retain an otherwise unchanged draft, and a failure toast does not name the visible recovery location. On the published head, Native fingerprint diff, PR Vouch and PR Size checks passed; the label-definition sync was skipped. CodeRabbit reports “Review skipped: draft pull request.” No full CI run or current-head configured code review has reported, so those remain gates.
  • Live isolated Linux web/server: Save/Cancel, takeover confirmation, recovery beside an occupied main draft, navigation and page reload, persisted ownership across an actual server restart, holding two queued successors after interrupting a preparing run, and Resume preserving the edit hold. Normal UI image/file upload, text-only edit, removal, reload and Save produced bound references or no references as appropriate. A text-only edit reused the original image ID with no image data in the command. Failed attachment restoration plus an actual isolated server stop retained ownership across restart and page reload; Save refused incomplete content and Cancel released the hold while keeping the server attachment. A delayed image fetch failed after the user typed while the server stayed online; successful cleanup retained that text beside the unchanged main draft. Clearing the retained draft removed its chip. A simulated missing persisted image triggered a visible refusal while retaining the server image and edit token; the browser's actual storage quota was not filled.
  • Fixtures used normal server commands and disposable state; no provider was started. Natural provider completion/failure races were covered by deterministic runtime tests, not a live provider run. Capability negotiation was test-verified; no live mixed-version, relay or tunnel pair was exercised.

Web evidence

Same disposable message and 1280×800 viewport. Appearance is similar; the behavioral proof is the persisted server hold and lifecycle checks above.

Before (main):
Before: local queue editor

After (rebuilt head):
After: queue editor backed by a durable hold

Save and Cancel recording

Simulated missing persisted image: Save refuses and retains the server attachment:
Missing attachment guard

Recovered text typed during a failed image load, beside the main draft:
Recovered text after failed attachment restoration

Remaining review

Still draft, as requested by Julius, pending current native evidence and human review. The original videos above do not replace testing the rebuilt mobile Save/Cancel, close/reopen, takeover, and attachment-recovery flows.

Models used in the earlier rebuild: GPT-6 Astra (tests), GPT-6.1 Sol (implementation), Claude Opus 5.5 and GPT-6 Sol (review). Earlier harnesses: T3 Code through Codex and Claude Agent. November 1 maintenance: OpenAI Codex desktop harness; exact model identifier unavailable.

Note

This comment is posted by Julius' dot

The native mobile edit, Save and Cancel flow changed, but the PR explicitly leaves it manually unverified. Please add before/after mobile evidence and a short recording showing an edit held through turn completion, then Save or Cancel, as required by the verification guide. Keep this in draft until that evidence is added.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a cross-platform queued-message editing workflow with persisted server holds, new commands, event-sequence coordination, and changes to queue scheduling and presentation. Its broad runtime impact and an unresolved queue-lifecycle risk require human review.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Preserve the dirty edit when another client takes ownership.

When queuedRunEditOwnership reports "lost", recoverQueuedMessageEdit moves the edit only if the thread composer is empty. Otherwise, it clears the edit draft. The warning toast does not provide recovery.

Use the existing undo-backed discard flow for this conflict.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Preserve the edit when the thread draft is occupied.

When another client changes the queued run's edit owner, this client can enter the "lost" branch. If the thread draft already has text or attachments, keepable is false. endQueuedRunEdit then deletes the separate edit draft and cleans up its attachments. The edit cannot be restored after a restart because queued-edit keys are excluded during draft hydration.

Merge the edit into the thread draft before ending edit mode. Preserve attachments beyond the send limit so the user can trim them later.

Suggested fix
-    const keepable =
-      editDraft.text.trim().length > 0 &&
-      threadDraft.text.trim().length === 0 &&
-      threadDraft.attachments.length === 0;

Taking over this one for maintainer batch composer-chat-19. I will rebuild the queue edit hold against current main, preserve the original commits, and verify the server lifecycle and shared clients before publishing changes. Native mobile evidence and human review remain explicit readiness gates. Credit to @Andrew-Forster and @GLDRoger for the original implementation and failure/reordering analysis.

Updated this branch with main in 48fcc41045 and a navigation follow-up in d8e9db9f0d. This keeps Julius's ownership/recovery rebuild and the existing contributor history.

The integration preserves Send now without letting it bypass an edit hold. I also reused main's shared edit lifecycle after reproducing two navigation regressions; both now pass, including keeping newer text when an older save finishes.

Current-head CI is green, and GitHub reports no merge conflicts. Local checks passed except an installation-detection test that also fails on unchanged main on Windows and a browser-start timeout; both browser suites passed separately.

Keeping this draft for current native-device evidence and maintainer review. The older recordings are still linked, but aren't being presented as validation of this updated build.

Resolved the new main conflicts in 7de0ad1 and 766a98b. GitHub now reports no conflicts. Kept the updated queue layouts and preserved the edit holds and draft recovery. Typechecks, lint and formatting pass; all 7 browser regressions and 9 server hold tests pass. The changed-file run has one unrelated Windows install-detection failure, reproduced against main. Keeping this draft for current native evidence and maintainer review.
