fix(web): settling the open thread advances immediately - #27309
Settling or snoozing the open thread waited for the server reply before opening the next one. The row left the list right away (the optimistic preview from #11408), but the route stayed put. #11408 kept that wait on purpose, so a quick second press could act as undo.
That broke rapid clearing. The second Ctrl+Shift+S landed on the still-open, already-settled thread and un-settled it. It jumped to the top of the active list, the next settle advanced from there, and the sidebar scrolled all the way up.
Fix
Settle (hotkey, row action and drag-to-settle) and snooze now start the command, open the next thread straight away, and then wait for the reply. Each press now settles the next thread. Undo is Ctrl+Z, from the "Settled N threads" notice.
If the server rejects the action, the thread rolls back into the list and the error toast shows as before. You stay on the thread you moved to.
shouldNavigateAfterThreadPark and its test table are gone, since nothing calls it anymore. The hotkey still un-settles a thread that is already settled, for threads opened from the Settled shelf.
Surfaces: web and desktop share this code. Mobile and client-runtime have no "advance to the next thread" step, so web is the only surface that needed the change.
#26661 touches the same handlers. Whichever lands second will be rebased.
12 Ctrl+Shift+S presses at 250ms, starting partway up the active list, using the same seeded database for both runs. On the left (main), the third thread is un-settled, the list jumps to the top, and the next threads flip between settled and active. On the right, each press settles one thread and moves down the list in place.
No new test. The behavior lives in the Sidebar handlers, and no existing test mounts the full Sidebar, so a test would mean heavy UI wiring for a few lines of ordering. vp run check:changed passes.

Macroscope's review found this PR approvable — Settling or snoozing the open thread now advances immediately, skipping threads whose actions are still pending. Existing error reporting and undo support remain, keeping the change limited to a recoverable navigation interaction.

Walkthrough
Sidebar settle and snooze actions now start forward navigation before awaiting operation results. Forward-navigation candidate selection excludes threads that are settling or snoozing. The shouldNavigateAfterThreadPark helper and its tests were removed.

Merge Risk: Low · up to 18da1
Settling the open thread now advances immediately in the common case. In the narrow case where the next destination is a new draft that opens slowly, a rapid repeated shortcut could briefly undo the settle. This is a small edge case, and the change is otherwise mergeable.

the prior-approval rule applies because this pr changes an intentional interaction. the description states that #11408 deliberately kept the route in place so a second press could undo. this diff advances before acknowledgment and leaves navigation advanced after a rejection. the rapid-clearing failure is a useful report, and the comparison supports it, but replacing the existing undo and failure behavior needs maintainer approval of direction and scope. please obtain that approval and request reconsideration, preserving the reproduction and comparison.
Merged current main again in 18da10ae48 (merge commit, no rebase). The only conflict was in Sidebar.logic.ts: main now exports THREAD_JUMP_HINT_SHOW_DELAY_MS. I kept that export and this PR's removal of shouldNavigateAfterThreadPark. The PR diff against main is unchanged: 3 files, +25/-109.
vp run check:changed passes on the merged head: format, lint, knip, typecheck, 7 test files (131 tests), react compiler.
Re-checked in Chrome against a dev server on the merged head, using six Replay (dev) threads. Three Ctrl+Shift+S presses 250 ms apart moved delta → charlie → bravo → alpha. The Settled count reached 3, and the "Settled 3, Ctrl+Z to undo" notice showed.
CodeRabbit asked for a Sidebar test that holds settleThread pending. I added none. No existing test mounts the full Sidebar, and the browser run above covers the ordering.
On the CodeRabbit risk note: a repeat press on a thread whose settle is still pending returns early through settlingThreadKeysRef, so it cannot un-settle that thread.

Exclude pending parks from forward navigation
If A’s settle leaves its optimistic shell unchanged, settling B before A acknowledges can navigate back to A. Another settle shortcut on A then does nothing until its pending settle completes.

Prevent the shortcut from reversing a settle while the draft opens.
The new pending-thread filters can select this fallback while another thread is still settling. handleNewThread can wait for a project-file query before it navigates. If the current thread settles first, another settle shortcut can un-settle it while the draft is still opening. Navigate away immediately or suppress that reversal until the draft route is ready.

Test that navigation skips pending candidates.
Add a regression case for a settling candidate and a snoozing candidate. Keep each candidate in the ordered list and otherwise eligible, then settle the open thread and assert that navigation skips it. This covers a different condition from advancing before the open thread’s settle completes.

verified 2f6b147f249df3958804f7c3e24086d8097d3cab on this linux vm with the real dev server, repo Playwright, /usr/bin/google-chrome, and Codex gpt-6.1-sol through the web composer. created the project and conversations through the app, with no mocks or seeded fixtures. ran main first in a separate worktree, then the exact pr head, then the fix after reinstalling and restarting.
main reproduced the bug: three Ctrl+Shift+S presses 250 ms apart stayed on delta and un-settled it. the final head advances delta → charlie → bravo → alpha and persists all three settlements. the recordings use the same app-created conversations. to test the acknowledgment boundary deterministically, i briefly paused only the task server process while sending shortcuts, then resumed it; every command still went to the real server.
the original pr also reproduced a pending-turn regression: with Codex executing a shell command, settling bravo then alpha returned to pending bravo, where the next press was ignored. the six-line fix excludes pending settle and snooze targets. re-verification advances bravo → alpha → a new draft. the real server rejection of settling a running thread restores bravo and shows its error toast while retaining the draft route.
also passed on the final head: snooze advances before acknowledgment, Ctrl+Z restores snoozed and settled threads, background settlement preserves the current route, and the shortcut un-settles a thread opened from the settled shelf. vp run check:changed d1909d68f8a8864d13fcb214c116777a651e6684 passed through blacksmith-check. all 37 pr checks passed. two independent reviews approved the final sha.
before: main stays on delta with zero threads settled.
after: the final head reaches alpha with three threads settled.
