-1. Advance Nostr resilience validation with optional real-relay soak lane after deterministic suites.
-2. Finish supply-chain readiness evidence and release-protection policy.
-3. Expand operational runbooks and staged rollout evidence for security readiness closure.
+1. Continue feature-development parity polish in TUI v2 with user-driven UX gaps.
+2. Raise TUI v2 critical-path coverage beyond current gate floor (target >82% for `src/seedpass/tui_v2/app.py`).

 4. Execute a tagged release integrity run and attach evidence URLs in readiness checklist.

+- Discoverability parity improved in TUI v2:
+  - added full palette command reference (`help-commands`, alias `commands`)
+  - `help` now also renders in-app command reference in entry detail pane
