Merge PR #71 after commander review. Rebaselines DEV live evidence to 16666/16667, removes stale edge/frp blocker classification, keeps DB live and M3 patch-panel runtime as real blockers. Complies with HWLAB #78 / DC-DCSN-P0-2026-003 by preserving DEV-LIVE evidence boundaries and not treating Gate/UI as MVP success.
