- Line 608: The RightRail remount key should be removed so toggles such as
showConfidenceDetails persist across selection-count changes; in
src/components/services/services-navigator-page.tsx lines 607-608, keep
RightRail mounted and explicitly reset only invalid selection-dependent panel
state. In tests/audit-content-services-regressions.test.ts line 75, replace the
key-string assertion with regression coverage that verifies this behavior.

In `@supabase/migrations/20260714180000_patch_rag_and_corrector_scalability.sql`:
- Around line 63-78: Update the document title word trigger logic around the
DELETE/UPDATE cleanup and INSERT/UPDATE indexing conditions to use NULL-safe IS
DISTINCT FROM comparisons for status and title transitions. Preserve cleanup for
indexed-to-NULL changes and insertion for NULL-to-indexed or NULL-to-title
changes, then add regression coverage for each NULL transition.

In `@supabase/migrations/20260714190000_document_table_facts_trgm_idx.sql`:
- Around line 2-11: Replace the CREATE INDEX statement for
document_table_facts_text_trgm_idx with a no-op so fresh installations do not
build an index immediately removed by the later scalability migration. Preserve
forward cleanup for environments where the index already exists by updating the
later migration’s cleanup around document_table_facts_text_trgm_idx to use a
runner-compatible nonblocking operation, such as a concurrent drop, while
retaining the existing conditional behavior.

In `@src/components/services/services-navigator-page.tsx`:
- Around line 297-309: Update the metrics setup in the service navigator
component to compute separate checklist counts from selected services while
retaining match-wide counts for confidence metrics. Use the selected-service
counts for the checklist rows and related checklist display logic, and use
matchCounts throughout the source-confidence section; locate the affected logic
around serviceNavigatorMetrics, the rows array, and confidenceTotal.

In `@src/lib/rag-candidate-sources.ts`:
- Around line 185-207: Thread args.signal through searchTextChunkCandidates and
all other candidate-loader helper signatures, forwarding it to
callVersionedRetrievalRpc and applying abortSignal(signal) to direct query
builders. Preserve existing retrieval behavior when no signal is provided, and
add a regression test covering cancellation while a query is pending.

In `@src/components/services/services-navigator-page.tsx`:
- Line 22: Move the invalid-selection panel reset currently performed in the
useEffect near the services navigator selection logic into the selection update
path. Update the handler or state transition that changes the selection to clear
the local panel state immediately when the new selection is invalid, then remove
the corresponding state update from useEffect while preserving valid-selection
behavior.
