 Status: in_progress
 
 DoD:
-- repeated O(n) filtering in hot render paths is removed
-- tab counts and similar derived UI metrics use cached/derived snapshots instead of recomputing the same filters
-- existing UI e2e coverage stays green after the performance polish
+- UI modules expose stable hooks for diagnostics and targeted testing where the current DOM is ambiguous
+- console/runtime failures on critical pages are easier to attribute to a concrete page module
+- existing UI e2e coverage stays green after the observability/testability pass
 
 ## Next
 
-- `feat/frontend-observability-and-testability`
+- `feat/id-display-support`
