🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winReconcile a lost queued-run edit lease.
When another client clears
queueEditIdwhile the run remains queued, the cleanup effect keeps the mobile edit active because it checks onlyrun.status. The visible cancel action then sends the staleedit.editId. The server rejects that ID, and the callback does not exit edit mode for the failure.Compare the local edit ID with
queueEditIdin the effect and treat anulllease as lost. Apply the same check before sending cancellation.Suggested fix

@coderabbitai review The stale-editor finding was fixed in cb149ac and you confirmed it resolved. The fix is still present on the latest head. Please re-review and update the review verdict. |

Retested head The server typecheck still fails at Reproduction: run The 93 focused queue-edit, mobile draft, shared execution/command, and web draft tests passed on this integration. Web, mobile, contracts, and client-runtime typechecks also passed. The earlier stale-edit lease guard is present on both web and mobile; this comment concerns the remaining typecheck failure, not that resolved finding. Browser reproduction: reopening a held message loses its editorOn the same integration, I reproduced a separate client failure in Linux Chromium using an isolated thread seeded with two held queued messages. Clicking the first message's pencil acquires a new edit lease, but the composer immediately becomes blank. The queue row says "Editing", with no Update or Cancel controls.
Expected: reopening the held message keeps its editor and Update/Cancel controls available. Please handle the projection lag when acquiring the lease and add a regression test for that ordering. This is a new acquisition race, distinct from the previously resolved stale-editor finding. The 93 passing focused tests do not cover this browser behavior.
Verification: GPT-6 Astra / Codex in T3 Code. Browser evidence uses isolated fixture data; no provider prompt was sent. Native mobile, Electron, and relay UI behavior were not freshly verified. |

@shivamhwp thanks for catching both. Fixed in bacd935, with the mobile test mock updated in f8c9469. The editor now keeps the acquisition receipt sequence and waits for the thread projection to catch up before checking ownership. Both clients use the same check, including immediate Cancel. A newer projection still closes an editor whose hold was cleared or taken over. The provider test now uses the current provider-core API. The server typecheck passes locally, 111 focused client tests passed, and CI is green on f8c9469. Removing the sequence guard made both acquisition regressions fail; restoring it passed. @coderabbitai review |

Note Written by Hi! We are cleaning up open PRs, and this one does not say which model or harness was used to create it. If this change is really important, we recommend rebuilding the PR with a newer model and noting the model and harness in the PR description. |
If the active turn finishes while a queued message is being edited, the original text can start before Save. Import [upstream pingdotgg#15612](pingdotgg#15612) to acquire a server edit hold before opening the editor, keeping queue order until Save or Cancel. Web, desktop, and mobile share the hold commands. Stale editors cannot overwrite a newer edit, and existing Stop/restart pauses remain held. Includes upstream regression tests and a fork surface assertion for the Editing indicator. Validation: draft push gate passed changed-file checks and workspace typecheck. Integrated browser verification passed edit hold acquisition, ending the active preparing run while editing (original stayed queued), Save dispatching revised text, Cancel keeping original text, reopening the editor, and Save/Cancel preserving a paused queue. Provider execution was unavailable in the isolated environment; orchestration regression tests cover provider turn completion. The full publish gate passed workspace lint/format, typecheck, and tests, including 6,330 server tests. Published through `pnpm pr:ready`; required GitHub checks are pending. Native mobile verification is unavailable because Device support is off; desktop uses the verified web flow without shell changes. Imported from Andrew Forster’s upstream PR, adapted with Codex (gpt-6.1-sol).

Fixes #15611. Also reported in #15717.
Problem
If a turn finishes while you're editing a queued message, T3 can send the original text before you save.
Fix
The server holds that message until Save or Cancel. Save sends the revised text; Cancel keeps the original. Neither interrupts the current turn or resumes a queue paused by Stop or a restart.
Queue order is preserved, stale editors cannot overwrite newer edits, and waiting on an edit no longer keeps the thread showing Working/Thinking. Web, desktop, and mobile use the same commands.
The author withdrew the overlapping draft-protection fix in #15911 in favor of this PR. Maintainer review is still pending.

Testing
Regression coverage includes dispatch during editing, Save/Cancel, queue order, stale edits, existing queue pauses, and completion status.
On
7e2d55741, all CI build, lint, typecheck, and test jobs passed. The two repaired suites also passed locally (37 tests):pnpm exec vp test run packages/client-runtime/src/operations/commands.test.ts apps/server/src/orchestration-v2/QueuedRunEditing.test.ts --maxWorkers=1Manually tested on Windows: leave an edit unsaved while the response finishes, then save and receive the revised response. Minimizing and returning also preserves the edit. Full app-close/reopen and native mobile flows have not been manually tested.
