 # Completed slices
 
+## DFG-14 durable graph navigation
+
+### Changed
+
+- Released the fixed `graph-browser@5` template and DocForge 0.8.0.
+- Kept the loopback listener alive across short-lived MCP standard-input transactions with a
+  browser-renewed lease, while preserving explicit process termination and bounded abandoned-page
+  cleanup.
+- Added a visible disconnected state instead of leaving stale controls to fail silently.
+- Added pointer and keyboard resizing for both side panels.
+- Made the unblurred modal natively resizable and draggable by its constrained title bar.
+- Added generic topology-derived Primary focus, Children, and Edge & context navigation sections.
+- Arranged neighborhoods by shortest-hop rings and applied distinct role palettes that darken
+  progressively by hop distance, capped at fifty percent.
+- Kept all category and color decisions client-side without changing project graph facts.
+
+### Verification
+
+- Focused HTTP tests cover heartbeat renewal, bounded lease expiry, non-daemon listener ownership,
+  and the unchanged token/read-only boundary.
+- A deterministic JavaScript harness proves topology roles, hop rings, and distance shading.
+- Embedded JavaScript syntax and interaction-contract checks cover panel resizing, modal movement
+  and resizing, unblurred backdrop behavior, grouped navigation, and lease renewal.
+- Ruff, formatting, compilation, the complete warning-strict suite, and live project-bound viewer
+  checks pass.
+
+### Limits
+
+- Panel widths, modal geometry, viewport position, and open dialog state are not persisted.
+- Topology roles are presentation aids. They do not replace project-authored relationship meaning.
+- Background-browser timer throttling is tolerated by the three-minute lease but may delay cleanup.
+
+### Next gate
+
+No further gate is planned. Measure use before adding saved layouts, minimaps, or export.
