The review item was correct. Working-section membership (isThreadWorking in packages/client-runtime/src/state/threadInbox.ts) is wider than isRunning (= !threadRuntimeCanArchive): it also covers runtime waiting, idle (a finished turn with held background work) and queued with no active run. resolveSidebarThreadStatus (Sidebar.logic.ts) maps those to 'Working'/'Waiting', and that status outranks the 'Done' unread marker in SidebarThreadRow, so 'Mark unread' still had no visible effect on them. ThreadActionMenuState now has a separate isWorking flag, computed with the existing isThreadWorking predicate at both builder call sites (Sidebar.tsx and useThreadActionMenu.ts). The mark-unread item is disabled when isRunning || isWorking, and Archive still uses only isRunning. Keeping isRunning in the condition keeps the repro test from factory/repro-24934 passing unchanged. The existing builder test gained a row for a thread that is Working but not running. No new regex or parser.

Fixes #24934

Reproduction on main

Commit 1a1f9ac (origin/main). Ran the web app with T3CODE_DEV_SEED=0 vp run dev (fresh database, Working section on by default) and added a small git project via t3 project add. Put two threads into the Working section with a scratch copy of the dev Replay ACP agent whose turns wait 10 minutes: (A) a thread on its first run, so it has no completed run; (B) a thread whose first turn completed and whose second turn was still running. Expanded the Working section in the sidebar and right-clicked thread A: the menu listed 'Mark unread' (while 'Archive thread' was disabled because the thread was running). Clicking 'Mark unread' closed the menu and nothing changed: the row still read 'Working', no unread marker, no toast or error. Did the same on thread B with the same result: no visible change. The client sends thread.mark-unread with reportFailure:false; for A the server rejects it ('has no completed run to mark unread'), and for B the Working status outranks unread in the sidebar.

Tests

vp test run apps/web/src/components/threadActionMenu.logic.test.ts: 4/4 passed. vp run check:changed: format, lint, knip 1/2 and 2/2, typecheck (2 packages), test (9 files) and react compiler (3 files) all passed.

Not in this change

• The sidebar multi-select bulk menu (Sidebar.tsx, 'Mark unread (n)') still marks every selected thread, including running ones; it applies to mixed selections, so whether to filter or disable it is a separate decision.
• Open PR fix(web): hide ineffective mark unread actions during active runs #25060 proposes hiding the action during active runs; this fix disables it instead, matching Archive.
• The sidebar multi-select bulk 'Mark unread (n)' (Sidebar.tsx) still marks every selected thread, including Working ones; it applies to mixed selections.
• Threads whose status is Approval, Input, Request, Failed or Limited also outrank the 'Done' marker, so Mark unread shows nothing visible there either; those are outside the Working section this issue covers.

Approvability

Verdict: Approved at 6684cac

Macroscope's review found this PR approvable — Mark unread is disabled while a thread is running or belongs to the Working shelf. The change is confined to menu availability and does not alter stored data or thread execution.

Walkthrough

The thread action menu now receives whether a thread is working. Mark unread is disabled when the thread is running or working. Tests cover running, working, and idle thread states.

Full details: Title check

Explanation

The title "fix(web): running threads no longer offer Mark unread" matches the main change: the Mark unread action is now disabled for running and Working-section threads in the thread action menu. It follows conventional commit format and is specific. The title names only running threads, while the change also covers Working threads that are not running. This is a minor narrowing, not a mismatch.

Full details: Description check

Explanation

The description covers the problem, the change, scope with a linked issue (#24934), and verification with focused tests and a reproduction on main. It follows the template's sections. The Evidence section is a placeholder and says before/after screenshots are still being captured, which the template requires for UI changes. Because of that gap, the description is not fully complete, but it is mostly complete.

Resolution

Attach the before and after screenshots (or a short recording) of the sidebar thread menu, as the template requires for UI changes, and replace the placeholder text in the Evidence section. The description also contains a duplicate bullet about the sidebar multi-select bulk Mark unread action in the Not in this change section, which should be removed. The description should also end with the model and harness that did the work, as the template requests.

Full details: Out of Scope Changes check

Explanation

The changed files are threadActionMenu.logic.ts, threadActionMenu.logic.test.ts, Sidebar.tsx, and useThreadActionMenu.ts. Each change adds or uses the isWorking flag for the single-thread Mark unread gating, or tests that gating. The changes are small (about +23 lines in total, per the summary). The PR states that the multi-select bulk action and non-Working statuses are not changed. No unrelated code change appears in the summary. The Evidence section is a placeholder and is not a code change. Uncertainty: the summary is AI-generated, and the full diff was not read, so the absence of other changes is inferred from the summary.

Full details: Linked Issues check

Explanation

[#24934] The issue requires that no "Mark as unread" option appear for threads in the Working section. The PR keeps the item and sets it to disabled when isRunning || isWorking is true. The isWorking flag uses isThreadWorking, so the Working-section membership is covered. The item still renders, so the stated expected outcome is not met. The PR description and the PR summary both state that the fix disables the action rather than hiding it. The added builder test asserts a disabled state for a Working thread, not an absent item. The reproduction on main shows the item present and clickable for Working threads. Disabling the item is a partial fix. The code evidence for the gating itself is consistent with the Working-section scope (Sidebar.tsx and useThreadActionMenu.ts both pass isWorking: isThreadWorking(thread)). The sidebar multi-select bulk action is outside the single-thread menu and is not addressed, which the PR states explicitly.

Resolution

Omit the "Mark unread" item from the thread action menu when isWorking is true, instead of disabling it. Keep Archive gated only by isRunning, as the PR intends. Update the builder test so that a Working thread asserts the item is absent. Update the repro test from factory/repro-24934 so it asserts absence for running threads too, if it currently asserts a disabled item. Re-run the affected test file.
