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.

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.

Clear requests when the dialog starts closed.

If readProject() accepts a request but the project disappears before the host renders, the dialog mounts with open={false}. Base UI does not mount its popup in that state, so onOpenChangeComplete(false) cannot clear the request. If the project returns, the stale dialog opens unexpectedly. Clear the request when the project becomes null; do not rely solely on the close-completion callback. (raw.githubusercontent.com)

✅ Confirmed as addressed by @juliusmarminge

JJulius Marminge14d ago

Confirmed. Main closed the request from an effect when the project went null; this PR's onOpenChangeComplete never fires for a dialog that mounts closed. Fixed in cf9aed4fb7 without an effect: openAddProjectToMachine subscribes to the project (subscribeProject) and the request ends when it goes null, so the dialog is back to open and onOpenChangeComplete is gone. Test: AddProjectToMachineDialog.browser.test.tsx "does not reopen for a project that vanished before the dialog showed" (fails on the previous head).

CcoderabbitaiBot14d ago

@juliusmarminge Thanks. The supplied code addresses this finding: subscribeProject clears the request when the project becomes null, even before the host renders. Cleanup no longer depends on onOpenChangeComplete. The reported regression test targets the original failure case.

Drop command palette actions when no palette is mounted.

installChatRouteCommands(router) registers chat.new globally without a route or mount guard. On routes such as /pair, this command can call openCommandPalette, while RootRouteBranch renders no CommandPalette. The action remains in Zustand and can open a stale palette when the user later enters the app shell.

JJulius Marminge14d ago

Confirmed, and this PR introduced it: on main the window event had no listener without a mounted palette, so it was dropped. Fixed in cf9aed4fb7: openCommandPalette returns early unless isCommandPaletteMounted(). Test: commandPaletteCommands.browser.test.tsx "drops a request made while no palette is mounted" (fails without the guard).

CcoderabbitaiBot14d ago

@juliusmarminge The supplied code confirms that openCommandPalette checks isCommandPaletteMounted() before dispatching any action. This prevents unmounted requests from leaving stale state in the store and addresses the finding.

Reset the shared project mock in setup().

project is module-level mutable state. Each test resets value, but neither test clears listeners. The browser-test guideline requires a setup() call at the top of each test for shared mock state. A retained listener can receive notifications from a later test.

87 - 9:
9Add a reset operation to the hoisted `project` mock that clears its value and
10listeners, and define a `setup()` helper that resets the mock and sets
11`PROJECT`. Call `setup()` at the start of each test in the
12`AddProjectToMachineDialog` suite instead of setting the project directly, so
13tests do not retain listeners across runs.

✅ Addressed in commit ac17d85

Fixed in ac17d85305: the mock gains a setup() that resets the project and clears its listeners, called at the top of each test.

@juliusmarminge Thanks. The confirmed setup() change addresses the shared mock state and listener cleanup concern.
