Lands sections 6 and 8 of relocate-brouter-to-dedicated-host on top of the host compose in #291. ## Observability (section 6) - **Prometheus**: new `brouter-cadvisor` job scraping `10.0.1.10:8080` over the vSwitch, labeled `host="brouter"`. - **cAdvisor sidecar** on the dedicated host's compose (`--docker_only --whitelisted_container_labels=trails.cool.service`) so metrics only cover trails containers, never the operator's unrelated workloads on the shared box. - **Promtail sidecar** on the dedicated host, Docker SD with relabel- drop on missing `trails.cool.service` label, pushing to flagship Loki at `http://10.0.0.2:3100/loki/api/v1/push`. - **Flagship compose**: Loki now publishes port 3100 on the vSwitch IP only (10.0.0.2:3100) — Hetzner Cloud firewall blocks it from the public internet. - **Grafana dashboard**: `brouter.json` — scrape up/down, request rate (from Planner-side `brouter_request_duration_seconds`), p50/p95/p99, container memory/CPU, Loki logs panel. - **Alert**: `brouter-scrape-down` fires on `up{job="brouter-cadvisor"} < 1 for 2m`; `noDataState: Alerting` so a total scrape failure still pages. Operator needs one UFW rule on the dedicated host for the cAdvisor port — documented in `infrastructure/brouter-host/README.md`. ## Documentation (section 8) - `CLAUDE.md` — hosts table + updated deployment table with SSH targets per workflow; BRouter host SSH is `-p 2232 trails@...`, different key. - `docs/architecture.md` — Hosting section rewritten to cover both hosts, vSwitch boundary, and the observability-scoping rationale for the shared dedicated host. - `docs/deployment.md` (new) — full operator runbook: host layout, first-time BRouter provisioning, SOPS rotation (including the macOS `SOPS_AGE_KEY_FILE` gotcha), cutover procedure with rollback, manual workflow triggers. Task 8.4 (infrastructure/README.md) skipped: that file doesn't exist and the ground is covered by brouter-host/README.md + docs/deployment.md. ## Validation - `docker compose config` on both the flagship and brouter-host compose files — both validate. - `pnpm typecheck`, `pnpm lint`, `pnpm test` — all clean (full turbo cache hits; no code changes in this commit).
