Multiple workspaces can share one checkout directory. Agent and terminal
status, sidebar tabs, and ownership now attribute strictly by workspace ID,
so a running or blocked agent in one workspace no longer shows up on its
same-directory siblings.
A one-time startup migration backfills workspace IDs onto legacy agents, and
every agent and terminal is created with one thereafter. Directory lookups
remain only for genuinely folder-derived git facts (branch, diff) and the
archive-by-path adapter.
Two breakages surfaced when CI started running desktop tests:
- Root vitest.config.ts replaced default exclude with `["**/.claude/**"]`,
losing `**/node_modules/**`. Desktop has no local vitest config, so
vitest scanned into `node_modules/zod/src/v4/classic/tests/*.test.ts`
and failed on missing peers (`@web-std/file`, `recheck`). Spread
`configDefaults.exclude` so node_modules stays excluded.
- window-manager dark titlebar color changed from #18181c to #181B1A in
963c7926 (white-flash fix) but the test was not updated. Update the
expected color to match the new intended behavior.
message-input.tsx imports ./composer-height-mirror, which only exists
as .web.ts / .native.ts / .d.ts. Metro picks the right variant at build
time, but vitest was using Vite's default extension list and failing to
resolve the import — breaking app tests in CI.
Prepend `.web.*` variants to `resolve.extensions` in both the root and
app vitest configs so test runs (which already alias react-native →
react-native-web) pick the web implementation, matching what Metro
does for the web bundle.
Route all git checkout queries through WorkspaceGitService instead of
shelling out to git on every call. This makes fetch_agents_request
instant when warm (cached in-memory snapshots) and deduplicates
concurrent cold-start refreshes via ensureWorkspaceTarget.
- buildProjectPlacementForCwd now uses workspaceGitService.getSnapshot()
- worktree-session call sites use WorkspaceGitService
- Deleted getCheckoutStatusLite and its 4 return types from checkout-git
- Fixed cold-start thundering herd: getSnapshot deduplicates via
ensureWorkspaceTarget instead of spawning parallel git processes
- Extracted checkout-diff logic into WorkspaceGitService
