Why: T2 acceptance requires a verification record in this repo before the Dev combo pin. Evidence: backend 14 pkgs ok incl. cardsvc suite; real-binary mock #upload e2e (2 cards, action receipt, pin, dismiss, idempotent re-action); ui 13/13; frontend 9/9; combo make test+build PASS. Impact: docs/records only. Refs: docs/proposals/2026-09-30-ui-inbox-command-workspace.md T2; task card feature/inbox-r2
