   - inspector boards and context-aware lower pane behavior
   - default-shell UX work
 - TUI v2 remains available via `seedpass tui2`, but is no longer the active UI development target.
-- Remaining v3 parity/hardening gaps still visible from the shipped code:
-  - context-aware action strip should continue being tightened per entry kind
-  - restore / import guidance and final visual polish still need iteration
-  - additional legacy utility and maintenance affordances should continue moving into v3 screens where they improve discoverability
-  - profile-management flows now exist in-app, but still need broader polish around naming, confirmations, and operator guidance
-  - maintenance screens now have shared styling/status helpers, but still need final mockup-level polish and any future screens should adopt the shared pattern from the start
+- Recent v3 hardening shipped (2026-03-10):
+  - **Bug fixes:** replaced `sys.exit(0)` with `os._exit(0)` to prevent SIGSEGV on graceful exit; added TTY check to guard against non-interactive stdin preflight/password loops in tui3; fixed missing Binding import in pubkey screen.
+  - **Action strip rename:** "Seed" -> "Profiles" button for clarity.
+  - **Restore/import guidance:** more explicit warning messaging and mode guidance surfaced before recovery paths execute.
+  - **Profile management polish:** improved visual hierarchy, clearer success/failure summaries, and status icon treatment on profile and maintenance screens.
+  - **Maintenance screen visual polish:** status icons, bordered intro cards, stronger visual hierarchy across all maintenance screens.
+  - **Search graph navigation:** `multi_hop_neighbors` and `filtered_neighbors` added to `SearchService`; `LinkedItemsPanel` enhanced with keyboard navigation, kind filtering, and atlas context display.
+  - **Sort/filter controls:** keyboard shortcuts `s`/`f`/`\` for cycling sort/filter/clear; active-state toolbar highlighting; Clear All button on the main grid surface.

 2. Continue TUI v3 utility/maintenance carryover:

 ## 5) Next Slice Definition (Recommended Immediate Work)
 
-### Slice A: “Search Graph Navigation”
+### Slice A: “Search Graph Navigation” — COMPLETED (2026-03-10)
+
+All exit criteria met:
+- `SearchService.linked_neighbors`, `multi_hop_neighbors`, `filtered_neighbors`, and `relation_summary` are implemented
+- v3 exposes explicit sort/filter/clear affordances via `s`/`f`/`\` keyboard shortcuts and toolbar highlighting
+- linked items can be viewed, filtered by kind, and opened via keyboard from the inspector panel
+- focused search/atlas/v3 suites green at `181 passed`
+
+### Slice B: “Deep Graph + Atlas Handoff”
 
 Deliverables:
-- 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.
+- Deepen multi-hop graph traversal with richer pivot UX (breadcrumb trail, back navigation, grouped by relation type).
+- Extend atlas/search handoff so graph-pivot results flow through the unified `SearchService` result model.
+- Continue expanding inspector linked-items panel with atlas context and relation-type labels.
 - Keep the atlas/search/graph plan and control center synchronized with shipped behavior as this slice lands.
 
 Exit criteria:
-- one service-layer path can return linked neighbors and relation summaries for an entry
-- v3 exposes explicit sort/filter affordances instead of relying only on command-state
-- linked items can be viewed and opened from the inspector
+- multi-hop graph navigation is accessible from the inspector without leaving the main workspace
+- atlas context is surfaced alongside linked items in the inspector panel
 - focused search/atlas/v3 suites stay green
