+
+Implemented:
+
+- Replaced transient false missing-source states with explicit bootstrap
+  loading and propagated loading/error state to the map and source panels.
+- Added keyboard-correct analysis tabs, reliable skip-link focus, accessible
+  map/status regions and stable focus handling across workspace changes.
+- Added measured four-second coverage and fifteen-second map-analysis budgets
+  with visible completion and over-budget feedback.
+- Hardened 390-pixel mobile, 1366-pixel desktop and 2560-pixel ultrawide
+  layouts without changing map-first behavior.
+- Added a Playwright UX audit for every workspace, accessible control names,
+  delayed bootstrap, keyboard behavior, layout overflow and timing feedback.
+
+Validation:
+
+- Repository readiness passed backend compilation, 1,015 backend tests,
+  16 frontend tests, frontend typecheck/build and Alembic head
