fix(web): refresh the current branch when opening the picker#22807

Problem

After switching branches with git switch or git checkout in a terminal, the branch picker can keep showing the previous branch as current, even after it has been deleted. Opening the picker does not currently request fresh local status.

Change

Refresh local Git status when the branch picker opens, including through its keyboard shortcut. Add a local-only option to the existing status refresh RPC so this does not initiate a fetch or PR lookup. The existing client command invalidates cached refs afterward, updating the list and its current marker too.

When the checked-out branch changes, publish a snapshot that also clears the previous branch's cached remote counts and PR. Coordinate this update with in-flight remote reads using the existing per-repository lock. The local refresh may wait for an existing remote read, but starts no new remote work.

Scope and approval

This is a focused fix for an obvious stale-state bug in the existing branch picker. It adds no polling or settings. It covers the shared web and desktop picker; mobile behavior is unchanged.

vp test run apps/server/src/vcs/VcsStatusBroadcaster.test.ts: 11 tests passed. Regression coverage verifies branch updates without new remote reads, clears stale remote data for cached reads and existing/new subscribers, covers an in-flight PR refresh, and preserves cached remote fields in the response when the branch is unchanged.
vp test run packages/client-runtime/src/state/vcs.test.ts: 7 tests passed, including the existing ref-cache invalidation behavior.
vp run --filter t3 typecheck: passed after the RPC optional-field fix.
Initial vp run check:changed HEAD: format, lint, knip, generated GraphQL checks, and adjacent tests passed. Web typechecking failed in the unchanged MermaidDiagram.tsx because pele/lazy could not be resolved locally. CI build and typechecking subsequently passed at a1503cb.
Review follow-up vp run check:changed HEAD against a1503cb: all checks passed, including formatting, lint, knip, generated GraphQL checks, server typechecking, and the 10 broadcaster tests.
Response-consistency follow-up vp run check:changed HEAD against 67123a6: all checks passed, including server typechecking and all 11 broadcaster tests.

Model: gpt-6.1-sol. Harness: Codex in T3 Code.

Approvability

Verdict: Approved at 6584e01

Macroscope's review found this PR approvable — This is a focused fix for stale branch-picker state that adds an optional local-only refresh while preserving the existing refresh behavior by default. The new path is limited to picker opening, avoids fetch and PR lookup work, and has targeted regression coverage.

📝 Walkthrough

The branch selector requests a local-only VCS status refresh when its menu opens. The WebSocket handler forwards the option. The broadcaster updates local status and manages cached remote data across branch changes and concurrent refreshes.

Changes: Local-only VCS status refresh

Layer / File(s)	Summary
Define and handle local-only refresh `packages/contracts/src/rpc.ts`, `apps/server/src/vcs/VcsStatusBroadcaster.ts`, `apps/server/src/ws.ts`, `apps/server/src/vcs/VcsStatusBroadcaster.test.ts`	The RPC schema and WebSocket handler support the optional `localOnly` flag. The broadcaster skips remote reads for local-only refreshes, clears remote data after branch changes, preserves cached remote data on same-branch refreshes, and handles concurrent refreshes. Tests cover these behaviors.
Refresh status when opening the branch menu `apps/web/src/components/BranchToolbarBranchSelector.tsx`	The branch selector creates a refresh command and requests a local-only refresh when the menu opens for a valid working directory.

Review details

Systems and components

observed — apps/server (service) was modified; 3 changed files map to changed impact.
observed — apps/web (ui) was modified; 1 changed file maps to changed impact.
observed — packages/contracts (library) was modified; 1 changed file maps to changed impact.

Before / after behavior

observed — Modified behavior in apps/server/src/ws.ts: The vcsRefreshStatus WebSocket handler now passes input.localOnly ?? false to refreshStatus; previously it passed only the working directory.
observed — Modified behavior in apps/web/src/components/BranchToolbarBranchSelector.tsx: Adds a non-reporting vcsEnvironment.refreshStatus command for refreshing branch status.
observed — Modified behavior in apps/web/src/components/BranchToolbarBranchSelector.tsx: When the branch picker opens and was previously closed, refreshes local-only VCS status for the current branch working directory.
observed — Modified behavior in packages/contracts/src/rpc.ts: WsVcsRefreshStatusRpc replaces the direct VcsStatusInput payload with an inline schema containing its fields and optional localOnly: boolean.

Clear stale remote status when the branch changes.

If Git switches branches outside the application, this path updates the cached local branch but leaves the previous branch’s remote status in the cache. A later getStatus call or new streamStatus subscription can pair the new branch with the old branch’s PR and remote counts, even though this call returns pr: null. Clear or reconcile the cached remote part when the ref changes. Keep that update coordinated with in-flight remote refreshes.

🟢 Low vcs/VcsStatusBroadcaster.ts:527

A localOnly refresh on an unchanged branch returns hasUpstream: false, zero ahead/behind counts, and pr: null even when the cache contains real remote status. This path merges with null instead of previous.remote.value; merge the cached remote value so the RPC response matches the retained cache.
