 Agent control plane for Pearcord — send the same IPC messages the UI sends, read `view` snapshots, and run scripted journeys against a **live worker** or an in-process **headless** session.
 
+**Phase 805 (v0.8.772):** `runGuildMeshTriplePinsJourney` (3-peer pins). Bundle: `npm run test:ci-phase805`.
