Use the latest thread path for rendered blocking decisions.

When serverThread exists with worktreePath: null and the draft still has a non-null worktreePath, activeWorktreePath uses the draft path. The rendered row and notice then treat a default ref that resolves to the main checkout as a worktree change and disable it. The click handler reads the server thread and permits the same ref because its current and next paths are both null.

Use the server thread path for the rendered helper when a server thread exists, or otherwise apply the same latest-state read used by the handler.

ScottN-PV9d ago

Fixed in 4e4e8fb503. When a server thread exists, the selector now uses its worktreePath, including null for the main checkout, and falls back to the draft only when there is no server thread. BranchToolbarBranchSelector.test.tsx covers a running thread on the main checkout with a leftover worktree draft, in both picker layouts. main stays selectable, and picking it updates the thread without a stop. Both cases fail without the fix.

@ScottN-PV Thanks for the fix. The supplied code now preserves the server thread’s worktreePath, including null, and uses the draft path only when no server thread exists. This makes rendered blocking decisions consistent with the click handler for the reported case.

The reported regression tests cover both picker layouts. I have not run them independently.

Use the stored worktree path in the post-create guard.

When forceNewWorktree is true, createRefMutation targets the project root, but readLatestThreadState() reports the rendered activeWorktreePath (null) instead of the thread shell’s current path. If another client moves the thread and starts a run while ref creation is pending, the guard compares null with null and falls through to setThreadBranch, which submits worktreePath: null. The server can then detach the active provider session and interrupt the run. Read the latest shell path for currentWorktreePath here, while keeping activeWorktreePath as the intended next path.

Valid, and narrow. With multiple models selected, the selector treats the thread as having no worktree, so this guard compares null with null. Creating a ref in that mode needs a started thread, and multi-select is offered only on the draft route, which a started thread leaves right after its first send. The path sent worktreePath: null unguarded before this PR. I am leaving it out to keep this PR to one problem.

🟠 High components/BranchToolbarBranchSelector.tsx:451

Activating a base-ref row after another client assigns a worktree and starts a run calls setThreadBranch(refName.name, null), which stops that run because null differs from the latest worktree path. The latest-state guard comes after the stale isSelectingWorktreeBase early return, so it never runs on this path; recompute the base-selection condition from the latest thread state and check whether the worktree change is blocked before returning.

Include each ref’s worktree in row invalidation.

When a ref-only refresh changes VcsRef.worktreePath, the row item remains the ref name and extraData remains unchanged. The row can therefore retain an obsolete disabled value.

Fixed in d4d3df74ab: row invalidation now includes each ref's worktree path. The toolbar and panel tests now use the real list and cover a refs-only refresh in both directions. Both fail when this addition is reverted.

@ScottN-PV Thanks for the fix. The supplied code now includes each ref’s name and worktreePath in extraData, which addresses this finding. Your reported real-list tests cover refs-only refreshes in both directions for toolbar and panel modes.

Use the latest worktree path in the selection guard.

If another client moves the thread from worktree A to B after this render, the handler reads the latest runtime but still compares paths using A. Selecting a ref whose worktreePath is A can pass the guard, reuse A, and call setThreadBranch without reaching the post-checkout check. The metadata update can detach the active provider session and interrupt the run. Resolve the guard and selection target from the latest thread path.

Fixed in 76525dcd, unchanged in 371f9026. The selection guard and the selection target now read the thread's latest runtime and worktree path from the store when the handler runs, so a move from another client counts before the picker re-renders.

I could not reproduce the stale click in a running client. On both f827e4ae and 76525dcd the picker re-rendered about 0.4 s after the server accepted the move, and the list reloaded with the row disabled. This change is checked by reading the code only.

Preserve a present thread’s null worktree path after checkout.

For a non-default ref without an existing worktree, resolveBranchSelectionTarget retains the captured secondary path as nextWorktreePath. If another client moves the thread to the main checkout while checkout is pending and a run starts there, this fallback makes the recheck compare the stale path with the same target. The guard then allows the update. setThreadBranch skips its explicit stop because the target matches the captured path, but still submits the path through updateThreadMetadata. The server can move the thread back and detach the provider session, interrupting the run. Use the captured path only when latestThread is absent.

Fixed in 76525dcd. The post-checkout recheck now uses the latest thread's path, including null for the main checkout, and falls back to the captured path only when the thread is not in the store. setThreadBranch's session stop reads the same state. 371f9026 adds the same recheck after a ref creation, which had the same window.

Checked in a running client with a second client that moved the thread and started a run during a held checkout. On f827e4ae the picker moved the thread back and the run was interrupted. On 76525dcd the warning toast appeared, the client sent no metadata update and no stop, and the run completed. The ref-creation case interrupted the run on 76525dcd and completed on 371f9026. Captures are in the PR body.

The automatic base-branch defaulting effect can stop a newly started thread run, interrupting work that began after the effect was committed. Its captured threadStarted guard can be stale, and setThreadBranch then stops the runtime found by readLatestThreadState() before the expectedEmpty metadata update is rejected; skip stopping the runtime for automatic updates.
