reviewer: - **[P1] Commit the gate artifacts referenced by the receipts** — `docs/masterplan/dispatch-subagent-reconcile/gate-plan-receipt.json:5`  
  The new receipts reference `spec.md`, `plan.md`, and `plan.index.json`, but none are included in this new directory. A clean checkout cannot verify the recorded hashes or reproduce/load the reviewed plan. Commit those artifacts, or remove/adjust the receipts and event entries.
