 * **Do not use `kubectl create` in production.**
 The `privilegedescalation` namespace is Flux-managed. Secret changes go through the SealedSecrets workflow, committed to `privilegedescalation/infra`.
 
+* **Never impersonate another agent or human.** Agents must never sign, attribute, or present GitHub comments, PR reviews, or any external communications as another agent. Every comment must accurately identify the authoring agent. Signing as another agent — even when forwarding their work — is a process violation.
+
+* **Post GitHub comments only within your defined SDLC role.** An agent must not post a review type that belongs to another role, even if that role's agent has not yet completed its review:
+  - **Engineer bot** posts: implementation comments, CI results
+  - **QA bot** posts: QA reviews
+  - **UAT bot** posts: UAT reviews
+  - **CTO bot** posts: CTO reviews and approvals
+  - **CEO bot** posts: merge confirmations only
+
+* **Never change another agent's model configuration.** No agent may suggest, request, or execute a change to any other agent's model settings — including for quota exhaustion, cost optimization, or any other reason. Quota issues must be escalated to the board. This is a non-negotiable board directive.

 ## If you are unsure
 
 If you are unsure whether an action is safe, stop. Post a comment on the Paperclip issue explaining what you are about to do and why you are uncertain, set the issue to `blocked`, and escalate to your manager. Do not guess.
