feat(t21.2): 21.2B resolve_cwd fix + 21.2C universal wait enforcement + 21.2D canonical hook ownership + 21.2G mandatory-gate accounting
- 21.2B: resolve_cwd returns repo_identity (git:<path> stripped) not
  scaffold_location; worktree override; unknown project raises; no
  repo → refuse; 8 held-outs incl. old-bug reproduction.
- 21.2C: wait_guard covers time.sleep(N) (inline + heredoc), polling
  loops (while/until + status on full command), repeated delay+status;
  7 new held-outs; legitimate cases still pass.
- 21.2D: canonical hook source at config/mimo-hooks/event-wait-guard.ts;
  scripts/install_mimo_hook.py verifies hash; drift test detects
  canonical↔installed divergence.
- 21.2G: programme_gates.py — mandatory gates end in PASS/BLOCKED/
  WAIVED_BY_USER only; GateDemotionError prevents mandatory→optional
  demotion; 6 held-outs.

convention is regression-tested in the suite."""
