End-to-end verified on the dedicated host:
- All 4 containers up (brouter 1.7.9, caddy, cadvisor, promtail)
- Planet segments seeded (~10 GB in 1 min, not hours)
- Auth enforced: 403 without header, 200 with header from flagship
- Planner live with BROUTER_AUTH_TOKEN wired (module-level guard passed)
Remaining:
- 7.4 Flip BROUTER_URL in SOPS (the actual cutover)
- 7.5 Remove flagship brouter after 48h soak
- 7.6 Document rollback in final PR description
