Proactive panels reopened a completed turn's diff on every thread visit, even after the user closed it, because the user-choice revision is re-read on entry and never persisted. Remember the last offered turn in the persisted panel state so each turn's diff is offered at most once. The trigger also trusted the turn's checkpoint, which absorbs pulls and branch switches made between turns, so read-only turns opened an empty working-tree diff. Only open when the working tree has changes.

Suggested reviewers: Merge Risk: ⚪ Minimal · up to The reported stale-status path does not prevent a completed turn’s diff offer. No actionable merge-blocking issue remains after normal checks. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The change adds controls against repeated and empty automatic diff panels. A remaining timing case can show later workspace edits as a completed turn’s diff, but the review found no demonstrated expansion of access or server authority.

- Line 4834: Update the completion flow in ChatView so `gitStatusQuery.data` is
not treated as current while `useWorkspaceMutationRefresh` is refreshing after a
checkpoint; preserve `previousRunningTurnId` until refreshed Git status has been
processed, so stale status cannot consume completion eligibility.
In `@apps/web/src/rightPanelStore.ts`:
- Line 514: Update the replacement states created by `openFile` and
`upsertSurface` to preserve the current `proactiveDiffTurnId`, while allowing a
later proactive turn to replace it. Add a regression test covering dismissal,
another panel action, reload, and a repeated offer to confirm the same turn is
not offered again.

Note This comment is posted by Julius' dot Closing because two independently useful fixes are combined. At The before/after captures, recordings, and focused regression results are useful. Please split the dismissal-memory fix and the empty-working-tree guard into focused PRs under one underlying problem per PR, retaining the relevant evidence and linking back here for reconsideration. |

Split as requested. The dismissal-memory fix is #14705. |

Problem
With Proactive panels on, the diff panel keeps opening on its own in two ways.
accepted. The cause is the user-choice revision: it is re-read on every thread entry and never persisted, so a close from a previous visit is invisible to the next one. fix(web): small desktop behavior and UI fixes #12422 fixes the same loop for the pull request path ([Bug]: Sidebar opens and/or focusses MR every time opening a thread #12040) but leaves the diff path untouched.git pull, branch switches, and other threads' edits made between turns count as the turn's changes. In one real thread the agent only read files, yet the checkpoint reported 58 files and 3,956 lines. The panel then shows the working tree, which is clean. fix(server): attribute V2 turn diffs to the turn-start snapshot #11528 fixes the checkpoint baseline on the server; until then the trigger cannot trust the checkpoint alone.Fix
proactiveDiffTurnId, the last turn whose diff was offered automatically.openProactivetakes the turn with a diff request and refuses a turn it already offered. It records the offer even when it refuses because the user picked another surface or a pull request has priority, so a revisit does not retry. The record survives hiding the panel, closing the last tab, and reloading. A new turn is still offered once, which keeps the on-entry behavior from fix(web): open proactive panels when entering threads #10610 for turns the client has not offered yet.resolveProactiveTurnDiffActionkeeps the 3-file/50-line checkpoint threshold and also requires the working tree to have at least one changed file. It counts files, not lines, because git status reports untracked files with zero line counts. The data comes from thegitStatusQueryChatViewalready subscribes to.The diff still opens on Working tree, per #12139. No server or contract changes.
Same read-only thread and entry path. The turn summary reports 7 changed files, but the working tree is clean.
Closing the diff, switching threads, and coming back:
proactive-diff-reopen-before.mp4
proactive-diff-reopen-after.mp4
Thread A has uncommitted changes, so its diff opens on entry in both builds. The Before build runs the three changed files reverted to
main, which is why they appear in its working tree.Verification

ChatView's "newly completed turn" bookkeeping (shouldOpenProactiveTurnDiff, the first-entry special case) could be replaced by the persisted offer. It shares state with the pull request deferral, so that cleanup is left for a follow-up.Refs #11636, #12040, #12422, #11528, #12139.
