Problem

The command palette kept its open state in a component reducer. Every way in (sidebar buttons, Cmd+N, PR links) went through a window CustomEvent that an effect passed on to the reducer. Its shortcuts were one window listener that re-attached whenever the theme, keybindings, terminal or preview state changed. An open intent ("Add project", "New thread in...") was applied by a layout effect that dispatched back to the parent to clear itself.

GitActionsControl ran its own focus/visibility listener plus an interval and a timeout effect. BranchPicker measured its scroll fades two frames after opening and scrolled to the top from a previous-value effect.

Change

• Palette state store. commandPaletteStore is a zustand store driven by the existing reduceCommandPaletteUiState, and openCommandPalette dispatches to it directly. With no palette mounted (for example on /pair) the request is dropped, as the unheard window event was on main. The palette, theme and usage shortcuts are now one dispatcher scope (shortcuts/commandPaletteCommands.ts), installed in appInit. It is live only while a palette is mounted (useCommandPaletteMount, an explicit mount effect, since leaving the route calls no close handler) and reads the route, panels and theme when the key is pressed. Unmounting the last palette resets the store.
• Intents start a session. Each intent bumps session, and the palette view is keyed by it, so the view starts in the intent's submenu on its first render. The "Add project" and "New thread in..." submenus build their items while rendering (resolveAddProjectEntry), so they update as environments and projects load. Before, they kept whatever existed when the palette opened.
• GitActionsControl.
  • Elapsed time reads the shared second clock (useNowSecond).
  • The inline success row hides at a deadline (useDeadlinePassed).
  • The focus/visibility status refresh is one shared atom per checkout (vcsStatusRevalidation). As on main, every window focus and every switch to a visible tab refreshes, with the same 250ms debounce. This restores the subscribeWake option in createVcsStatusRevalidationAtomFamily, which https://git.cafe/pingdotgg/t3code/pulls/25152 removed while it had no consumer.
• BranchPicker. The fades update from a ResizeObserver attached in the list's ref callback. Typing scrolls the list to the top from the input's change handler. The resultsQuery prop is gone.
• AddProjectToMachineDialog. Instead of an effect, each request subscribes to its project and ends when the project goes away, even before the dialog shows. openAddProjectToMachine ignores a project that no longer exists. Each request remounts the dialog.

What this improves

• Sync removed. The palette no longer relays window events into a reducer, and its intent is no longer applied and then cleared from a layout effect. The git status refresh, elapsed timer and success timeout no longer each run their own effect. The branch picker no longer runs a previous-value effect.
• Renders avoided. The CommandPalette shell no longer subscribes to the theme, keybindings, terminal UI store, right-panel store or location. Theme, terminal or preview changes no longer re-render it or re-attach a window listener.
• Bugs fixed. None claimed. I found no regression test that fails on main for a user-visible bug here (see Behavior changes).

Behavior changes

• "New thread in..." with no projects loaded now opens the empty Projects submenu, which fills in as projects load. On main the intent waited for at least one project. Until then the palette opened at the root, and when projects arrived it jumped into the submenu and reset the query. CommandPalette.browser.test.tsx "opens New thread in..." passes here and fails on main for this reason.
• "Add project" with no connectable environment opens a "Connect an environment" row. Before, it closed the palette and went straight to Settings -> Connections. With one environment it opens the source list directly, as before.
• When an intent arrives while the palette is open (for example a PR link search), the palette view remounts from that intent instead of resetting its fields one by one.
• Typing in a branch picker scrolls the list to the top right away, not after the deferred results render.
• If its project disappears, the Add-project-to-machine dialog animates closed instead of unmounting. Before, a request for a project that no longer existed was set and then cleared by an effect; now it is ignored.
• An expired inline git success row stays in component state but is hidden; nothing reads it after that.

Not included

These are from the original unit. Removing the branch-default write in BranchToolbarBranchSelector and the live-branch draft sync in GitActionsControl needs the send path (useComposerSend, plus status plumbing in ChatComposer) to work out the branch itself. That is a change to the core send path, so both effects stay as they are on main.

Effects

• CommandPalette.tsx: 5 -> 1 (browse-navigation cleanup kept)
• GitActionsControl.tsx: 4 -> 1 (live-branch draft sync kept)
• BranchPicker.tsx: 2 -> 0
• AddProjectToMachineDialog.tsx: 1 -> 0
• BranchToolbarBranchSelector.tsx: 1 -> 1

Total: 13 -> 3. Other touched files have none.

Verification

• vp test run on CommandPalette.logic.test.ts, CommandPalette.browser.test.tsx (new: the intent path focuses the search input, not the Back button, which guards the https://git.cafe/pingdotgg/t3code/pulls/25072 class of regression), CommandPaletteContent.browser.test.tsx, shortcuts/commandPaletteCommands.browser.test.tsx (new), UsageToggleShortcut.browser.test.tsx and client-runtime vcsStatusRevalidation.test.ts: all pass.
• vp run check:changed: format, lint, knip, typecheck (7 packages) and tests (7 files, 56 tests) all pass.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This PR rewires command-palette lifecycle and global shortcuts while also changing production VCS refresh behavior and picker/dialog state management across several components. It additionally adds a directive suppressing an Effect static-analysis diagnostic, so the changes warrant human review.

Notes:

• No code objects were reviewed. Approvability was decided on eligibility alone.

Walkthrough

The changes centralize command-palette state and shortcut handling, update add-project dialog and branch-picker behavior, and add debounced wake-based VCS status revalidation with related Git action display updates.

Changes: Command Palette

Layer / File(s)	Summary
Palette state and intent handling apps/web/src/commandPaletteStore.ts, apps/web/src/commandPaletteBus.ts, apps/web/src/components/CommandPalette.logic.ts, apps/web/src/components/CommandPalette.logic.test.ts	The store tracks palette state and mounted instances. Open intents increment a session, and add-project entry resolution selects a connection, environment, or source view.
Palette views and intent rendering apps/web/src/components/CommandPalette.tsx, apps/web/src/components/CommandPalette.browser.test.tsx	The palette reads shared state and initializes its view and search context by session. It renders add-project and new-thread groups. Browser tests cover input focus and search text.
Shortcut registration and app wiring apps/web/src/shortcuts/commandPaletteCommands.ts, apps/web/src/hooks/useTheme.ts, apps/web/src/appInit.tsx, apps/web/src/shortcuts/commandPaletteCommands.browser.test.tsx, apps/web/src/components/UsageToggleShortcut.browser.test.tsx	App startup installs palette commands. The installer registers actions while the palette is mounted, and browser tests cover route and mount behavior.

Add Project Dialog

Layer / File(s)	Summary
Project request and dialog lifecycle apps/web/src/components/AddProjectToMachineDialog.tsx, apps/web/src/state/entities.ts, apps/web/src/components/AddProjectToMachineDialog.browser.test.tsx	Requests for absent projects are ignored. Accepted requests subscribe to project changes and increment a session. The dialog closes when its project disappears.

Branch Picker

Layer / File(s)	Summary
Branch query and list behavior apps/web/src/components/BranchPicker.tsx, apps/web/src/components/BranchToolbarBranchSelector.tsx, apps/web/src/components/WorktreeBaseBranchPicker.tsx	The picker replaces resultsQuery with query, resets list scrolling when the input changes, and observes list resizing for scroll-fade updates. Callers no longer pass the deferred result query.

VCS Status Refresh

Layer / File(s)	Summary
Revalidation contract and wake handling packages/client-runtime/src/state/vcsStatusRevalidation.ts, packages/client-runtime/src/state/vcsStatusRevalidation.test.ts	The revalidation atom family supports optional connection and wake inputs. Wake signals trigger a debounced refresh, and cleanup removes pending timers and subscriptions. Tests cover debounce and unmount cleanup.
Document wake and Git actions integration apps/web/src/lib/documentActivity.ts, apps/web/src/lib/documentActivity.browser.test.ts, apps/web/src/state/vcs.ts, apps/web/src/components/GitActionsControl.tsx	The web app signals revalidation on focus and visible-tab events. The Git actions control mounts revalidation for the active environment and working directory, and success messages expire by deadline.

- Around line 16-29: Update dispatchCommandPalette, used by openCommandPalette,
to return without changing Zustand state when no CommandPalette is mounted; use
the existing mounted-state check so actions dispatched on routes without a
palette cannot remain stale.

Review comments at @apps/web/src/components/AddProjectToMachineDialog.tsx:
- Around line 206-207: Update AddProjectToMachineDialog’s request handling to
clear the pending request when the project becomes null, rather than relying
only on onOpenChangeComplete(false); preserve the existing close behavior when
the dialog does complete closing.

- Around line 7-9: Add a reset operation to the hoisted `project` mock that
clears its value and listeners, and define a `setup()` helper that resets the
mock and sets `PROJECT`. Call `setup()` at the start of each test in the
`AddProjectToMachineDialog` suite instead of setting the project directly, so
tests do not retain listeners across runs.
