 ### 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.

 - Nostr relay actions mapped back through internal configuration via `app.services['nostr']`.

+## 6. Progress Log (2026-03-06)
+
+### Completed in this session
+- **Main grid reliability:**
+  - fixed v3 main-grid keyboard navigation by restoring focus ownership to `#entry-data-table` on workspace mount
+  - closing the command palette now restores focus to the main grid instead of leaving focus on a hidden input
+  - added focused regression coverage for default grid focus and post-palette keyboard navigation
+- **Search graph navigation baseline:**
+  - added `SearchService.linked_neighbors(...)` for deterministic incoming/outgoing link traversal
+  - added `SearchService.relation_summary(...)` for grouped relation counts
+  - v3 inspector now includes a linked-items panel with direct open-entry actions
+- **Grid control hardening:**
+  - v3 grid now persists the active search query across refresh/filter/sort changes
+  - added explicit in-app filter, search-mode, archived, and sort controls on the main grid surface
+  - palette command surface now includes `sort <...>` and routes search-mode changes through app actions for one consistent control path
