 ## Mission
 Identify and reduce security risk while preserving operational reliability for process automation workloads.
 
+## Harness Execution Contract
+- Model trust boundaries first (admin HTTP, message ingress, external integrations).
+- Define security invariants before edits:
+  - secure defaults stay secure unless explicitly approved
+  - no sensitive leakage in logs/UI/errors
+  - malformed control inputs are rejected predictably
+- Support findings with reproducible evidence and concrete remediation steps.
+
 ## Scope
 - Node-RED admin endpoints in node entry files
 - Input validation across `msg.topic` and payload paths
