 ## Known Gaps
 
-- **Search UI**: E2E tests exist but 2 of 5 are flaky (results display, empty state) — tracked in #118.
-- **Members**: Revoke invite E2E test is flaky — tracked in #118. 4 dependent serial tests may be skipped when revoke fails.
-- **Workspace settings**: No unit tests for the settings form (name/slug validation, delete confirmation).
-- **Auth forms**: No unit tests for form validation (email format, password requirements).
-- **Sidebar context**: No unit test for keyboard shortcut (⌘+\) registration and state management.
 - **OAuth**: GitHub and Google OAuth buttons are rendered but disabled ("coming soon"). Not a gap — intentionally deferred per architecture decision.
 - **Realtime**: Not implemented. Deferred to post-MVP per architecture decision.
