The Phase C1 keystone asset (Story B). Publishes the infra case study:
- architecture: 3 hosts / 162 containers / 78 compose stacks with the per-host split

- how the numbers are re-derived (verify_infra.py) rather than remembered
- no uptime percentage: availability is not measured, so the post says 'monitored'
- hire CTA (case-study convention)
