- W16.3 (陈风): F-11.1-2 CLOSED — confirmed W12.1 fix, strdup OOM protection already in place
- W16.4 (胡桐): Integrate check_agents_metadata into refresh_status.py as pre-gate (error→exit 1)
- W16.5 (周岩): Add Findings Summary to W13.3 network audit, register 3 findings
- W16.6 (赵码): Add Findings Summary to W13.1+W13.2 AI audits, register 8 findings (4 already W14-fixed)
