Ticket #61 PR #21 Review: pass_audit approved (resubmission) Security issue fixed: - Added `before_action :require_human_agent, only: [:approve, :reject]` - Checks `current_agent.agent_type == "human"` - Returns 403 Forbidden with clear message for unauthorized attempts - Added tests verifying non-human agents cannot approve/reject All acceptance criteria met: - ask_for_memory_deletion tool creates request record ✓ - Request includes memory_id, agent_id, reason, timestamp ✓ - Human can view/approve/reject deletion requests ✓ - Only approved deletions actually remove memory ✓ - All deletion attempts are logged (audit trail) ✓ - Agents cannot bypass this flow (authorization enforced) ✓ Test results: 300 examples, 7 failures (feature specs requiring Chrome - not code issues)
