   - deterministic filter/sort pipeline added for keyword / hybrid / semantic search modes

   - focused regression coverage added in `src/tests/test_core_api_services.py` and `src/tests/test_tui_v3_smoke.py`
+- Phase B baseline landed:
+  - `SearchService.linked_neighbors(...)` and `relation_summary(...)` now provide explicit outgoing/incoming graph navigation data
+  - v3 grid now preserves active search query across refresh/filter/sort changes
+  - v3 grid now exposes explicit in-app filter/mode/sort controls instead of palette-only command flow
+  - v3 inspector now includes a linked-items panel with direct open-entry actions
+  - focused regression coverage expanded in `src/tests/test_core_api_services.py` and `src/tests/test_tui_v3_smoke.py`

-  - richer sort/filter controls in v3
-  - linked-item navigation service methods and inspector consumers
+  - deeper linked-navigation workflows and richer graph-oriented pivots
   - deeper atlas/search handoff and graph-aware result workflows

 ### Slice A: “Search Graph Navigation”
 
 Deliverables:
-- Add linked-neighbor and relation-summary methods above the current atlas/search foundations.
-- Expose explicit sort and filter controls in v3 on top of the existing unified `SearchService`.
-- Add inspector linked-item navigation so users can browse outgoing/incoming relationships without raw JSON inspection.
+- Extend the new linked-neighbor and relation-summary methods with deeper graph pivots above the current atlas/search foundations.
+- Continue iterating on the new explicit v3 sort/filter controls on top of the unified `SearchService`.
+- Expand the new inspector linked-item navigation so users can pivot through relationships more fluidly without raw JSON inspection.
 - Keep the atlas/search/graph plan and control center synchronized with shipped behavior as this slice lands.
