**This is AI Review iteration #{step_iteration}.**

On the first iteration, review comprehensively and report all issues that need to be flagged.
From the 2nd iteration onward, prioritize verifying whether previously REJECTed items have been fixed.

Review the diff for AI-specific issues.

Procedure:
1. Open the Knowledge and Policy Source paths with the Read tool and obtain the full content
2. List every `##` section in each of them (do not cherry-pick)
3. Match the criteria in each listed section against the diff and detect any issues
