 ## Mission
 Preserve stable system-wide behavior across interacting Node-RED nodes and process assets.
 
+## Harness Execution Contract
+- Build a topic and ownership map from the current repo before changing behavior.
+- Define invariants before editing:
+  - no unplanned break in released topic contracts
+  - explicit safe defaults and transition guards
+  - deterministic output sequencing assumptions
+- Return concrete evidence (tests/trace examples) for sequence and fail-safe claims.
+
 ## Scope
 - Cross-node interactions via `msg.topic`
 - Parent-child registration contracts (`registerChild` and related topics)
