Merge Risk: 🟡 Moderate · up to Approval can lose a concurrent project edit, and switching chats during a turn can leave a proposal unresolved. These paths should be fixed before merging; a slow earlier save can also make an unattempted proposal impossible to retry. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to A reply can be presented for approval in the wrong conversation if the user switches conversations while it runs. A saved edit can also disagree with the review status shown in chat. The identified exposure is the open local project, not a demonstrated wider account or service boundary. Retained concerns

Keep completed turns in their captured session.
If the user selects another session while runAgentTurn is pending, the success path appends the assistant message to the currently displayed messages. chatRun persists that message in the captured session, but the retained review can appear in the newly selected session. Applying or discarding it then calls chatSetEditStatus with the wrong session ID, leaving the original proposal unresolved.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Do not report a slow save as failed.
waitForDocumentSaves() returns "timeout" when an earlier save takes longer than the timeout. In that case, this code returns "save-failed", and createAgentEditReview changes the status to "failed". That status is terminal: apply() returns the stored status, so the user cannot retry. The user then sees "saving failed" for a proposal that was never attempted, and the proposal is lost.
Map the timeout to a result the user can retry. Another option is to leave the review in proposed so the user can apply it again.

Invalidate the approval save when a live edit starts.
applyAgentDocumentIfCurrent checks revision before awaiting saveDocument. A user edit through useEditorSettings or useCaptions then calls setDocument, which changes the live document but does not change the write epoch. The approval save can therefore pass its post-save epoch check, replace the user edit, and record the older document as its undo base.
Suggested fix
setDocument(document, opts) {
+ supersedeInFlightWrites();
// No await to sit above: this write cannot fail, so recording it up front isImport supersedeInFlightWrites from ./undoStack with the existing undo-stack imports.
