- viz_routes: run verify_search_results before returning results. After the
accessible_owners expansion the viz can surface OTHER users' shared docs, so
it must drop ones the caller can no longer access (revoked share) — same as
the nc_semantic_search tool path. (Blocking review item.)
- access_filter: cache list_accessible_owners per user for 30s to keep the OCS
shares round-trip off the search hot path (failures aren't cached); document
the single-page OCS limitation; add a clear_accessible_owners_cache() test
helper. Comment the empty-accessible_owners MatchAny([]) edge case.
- verification: comment why cross-user eviction is a deliberate no-op (eviction
is scoped to the querying user's id, so a recipient's revoked access never
deletes the owner's points; the recipient self-heals via accessible_owners).
- algorithms: declare SearchResult.original_score (set by the viz route) so the
now-precisely-typed result list type-checks.
- tests: cross-user eviction-no-op safety test; autouse owners-cache reset in
the access_filter + shared-search tests; replace async-no-await qdrant fakes
with AsyncMock (clears SonarCloud S7503).
