+  running containers, container restarts with health verification, post-update
+  verification of every critical service (LiteLLM proxy, SearXNG, Zulip, Gitea,
+  PM2 processes, Hermes gateways), and rollback on failure. Consolidates the
+  raw shell scripts that previously did this piecemeal. This contract owns the
+  HOST-LEVEL weekly maintenance loop on the primary host plus Docker image
+  pulls ONLY for .116 and .7, while infrastructure-update owns the FULL-FLEET
+  cluster-wide wave (apt across the full PVE cluster + CTs/VMs AND its Docker
+  image Wave 3 across all stacks). Runs Sunday 2am ET. Owner:
+  ops (firstmate secondmate). Blast radius: an unverified image pull can break
+  LiteLLM (all agents lose inference) or SearXNG (search-stack down); a bad apt
+  upgrade can leave the host in a half-upgraded state. Pre-update backup check
+  and rollback are mandatory for this reason.

+
+Primary host is the maintenance host where apt updates apply. Docker image pulls
+span the two Docker ecosystems that run critical services. infrastructure-update
+runs the full-fleet cluster-wide wave (including its Wave 3 Docker pulls across
+all stacks/hosts); this contract runs a narrower host-level weekly pull limited
+to .116 and .7. Topology, CT IDs, and IPs are live-state fields — verify against
+`infrastructure-control.prose.md` (the source of truth) and the live system
+before mutating.

+
+## Requires
+
+- SSH/exec access to CT 116 (.116) and VM 109 (.7) for Docker operations
+- `apt`, `docker`, `docker compose` available on target hosts
+- LiteLLM master key available (Infisical vault, `LITELLM_API_KEY`) for health verification
+- `infrastructure-monitoring` run completed within the last 30 minutes — provides the pre-update health baseline used by the regression check
+- Writable backup directory `/tmp/infra-maintenance-backup-<date>/` on each mutated host
+- Proxmox snapshot of the primary host available (or confirmed not required) before apt phase
+
+## Continuity
+
+- Self-driven: weekly cron `0 2 * * 0` (Sunday 02:00 ET)
+- Also wakes on: explicit "infra maintenance" trigger from ops/abiba
+- Depends on `infrastructure-monitoring` for the pre-update health baseline — do not run if the last monitoring run is stale (>30 min) or RED; abort and escalate instead
+
+## Execution
+
+### Phase 0 — Preflight (snapshot/backup check + health baseline)
+
+1. **Capture health baseline** — run the `infrastructure-monitoring` postcondition checks (LiteLLM, Zulip, Gitea, SearXNG, Proxmox API) and record results as `health-baseline`. If any critical service is already down, **abort**: maintenance must not run on a degraded fleet.
+2. **Backup check** — confirm a Proxmox snapshot of the primary host exists OR `/tmp/infra-maintenance-backup-<date>/` was created this run. Snapshot critical config files into the backup dir:
+   - `/opt/inference-harness/docker-compose.yml`, `/opt/inference-harness/litellm_config.yaml` (CT 116)
+   - `/opt/search-stack/searxng/docker-compose.yml`, `/opt/search-stack/firecrawl-source/docker-compose.yaml` (VM 109)
+3. **Record image baseline** — `docker inspect --format '{{.Image}} {{.Config.Image}}' <container>` for every running container on .116 and .7; store digests in `image-baseline` so rollback can restore them.
+4. **Disk check** — `df -h` on each mutated host; abort if free space <20% (apt upgrade + image pulls need headroom).
+
+### Phase 1 — OS package updates (primary host)
+
+```bash
+# On the primary host only (VERIFY host against infrastructure-control first)
+apt update
+apt upgrade -y
+```
+
+- Capture `apt list --upgradable` before and after → store in `apt-state`.
+- If apt reports held/broken packages (`apt-get -s upgrade | grep -i broken`, or non-zero exit), **stop** — do not force. Record `held_broken` and go to rollback/escalate.
+- If `/var/run/reboot-required` exists after upgrade, flag `kernel_reboot_required: true` in `apt-state` but **do not reboot automatically** — that's a separate coordinated action (see infra-update Wave 4). Note it in the report.
+
+### Phase 2 — Docker image pulls
+
+Pull latest stable tags for every running container. Do NOT pin to `:main`/`:nightly` — use stable tags where the compose file specifies them; otherwise `latest`.
+
+```bash
+# CT 116 (.116) — inference harness
+cd /opt/inference-harness && docker compose pull
+
+# VM 109 (.7) — search + home stacks
+cd /opt/search-stack/searxng && docker compose pull
+cd /opt/search-stack/firecrawl-source && docker compose pull
+# any other running stacks on .7 (home stack, audiobookshelf) — pull per their compose files
+```
+
+- LiteLLM and SearXNG are the two explicitly required pulls; "any other running containers" means every stack with a compose file on .116 and .7.
+- Record pulled tag + digest per service in `image-baseline`.
+
+### Phase 3 — Container restarts with health verification
+
+Restart one stack at a time, verify health before moving to the next. Do not restart everything at once — a failure mid-wave must leave the rest running.
+
+```bash
+# CT 116
+cd /opt/inference-harness && docker compose up -d
+# VM 109
+cd /opt/search-stack/searxng && docker compose up -d
+cd /opt/search-stack/firecrawl-source && docker compose up -d
+```
+
+After each stack comes up, wait for health (max 120s):
+- `docker ps` shows the container `Up` (and `healthy` if a healthcheck is defined)
+- Service-specific probe passes (see Phase 4 probes)
+
+If a stack fails to come up within 120s, **stop the wave** and go to rollback for that stack only; do not proceed to the next.
+
+### Phase 4 — Post-update service verification
+
+After ALL updates (apt + images + restarts), verify every critical service is back up and matches the pre-update baseline. This is the regression gate.
+
+| Service | Probe | Expect |
+|---------|-------|--------|
+| LiteLLM proxy | `curl -sf http://192.168.68.116/litellm/v1/models` | 200 OK, models returned |
+| LiteLLM MCP gateway | `curl -sf http://192.168.68.116:4000/mcp-rest/tools/list -H "Authorization: Bearer $MASTER_KEY"` | 90 tools (23 RA-H OS + 67 GitHub) |
+| SearXNG | `curl -sf http://192.168.68.7:8888` | 200 OK |
+| Zulip | `curl -sf https://chat.sysloggh.net/api/v1/server_settings` | 200 OK |
+| Gitea | `curl -sf https://git.sysloggh.net/api/v1/version` | 200 OK |
+| PM2 processes | `pm2 jlist` (CT 100) | all pi-agent processes `online` |
+| Hermes gateways | SSH to Mumuni CT 114, Tanko CT 112; `systemctl is-active hermes-gateway` | `active` for each |
+
+Regression check: every service that was GREEN in `health-baseline` must still be GREEN. A service that was already RED (and caused a preflight abort) is excluded — but Phase 0 should have aborted before we got here.
+
+## Rollback Protocol
+
+If ANY service in Phase 4 fails to come back up (or regresses vs baseline):
+
+1. **Image rollback** — for the failing stack, restore the previous image:
+   ```bash
+   # Restore from recorded image-baseline digest
+   docker compose down
+   # Pin the service image to the recorded digest in compose, then recreate
+   #   image: <name>@sha256:<previous_digest>
+   docker compose pull && docker compose up -d
+   ```
+2. **APT rollback** — restore the primary host from the Proxmox snapshot taken/confirmed in Phase 0. If no snapshot, `apt install <pkg>=<old_version>` per package using apt history (`/var/log/apt/history.log`).
+3. **Config rollback** — restore configs from `/tmp/infra-maintenance-backup-<date>/`.
+4. **Re-verify** — re-run the Phase 4 probes on the rolled-back service. If still failing, escalate (do not loop — circuit breaker below).
+5. **Escalate** — send a Zulip DM to abiba + mumuni with: failing service, phase, baseline vs current, rollback actions taken, backup path.
+
+## Circuit Breaker
+
+- `max_retries: 2` per failing phase — after 2 rollback attempts on the same service, stop and escalate.
+- `window: 7200` seconds — no more than 2 retries within a 2-hour window.
+- `trip_action: escalate_to_fatal` — when tripped, escalate to fatal (abiba + mumuni + kwame) and pause; a human must clear before the next scheduled run.
+
+## Report
+
+After completion (or on abort), emit a receipt (JSON) to `~/.hermes/runs/infrastructure-maintenance/` and send a Zulip DM summary:
+
+```
+🛠 Infrastructure Maintenance — YYYY-MM-DD
+
+Phase: apt | images | restarts | verify | rollback
+Primary host: <host>
+APT: <N> packages upgraded, <M> held/broken, kernel_reboot_required=<bool>
+Images pulled: LiteLLM <tag>, SearXNG <tag>, <others>
+Services: all GREEN | <service> FAILED (rolled back)
+Baseline regression: none | <details>
+Backup: /tmp/infra-maintenance-backup-YYYYMMDD/
+Escalation: none | warning | critical | fatal
+```
+
+## Verification Postconditions
+
+- All critical services running after update (Phase 4 all GREEN)
+- No regressions from pre-update health baseline (Phase 0 baseline)
+- Docker containers on latest stable tags (`image-baseline.pulled_tag` recorded)
+- APT packages up to date with no held broken packages (`apt-state.held_broken == 0`)
+
+## Related Contracts
+
+- `infrastructure-update.prose.md` — owns the full-fleet cluster-wide wave INCLUDING its Wave 3 Docker image updates across all stacks (SearXNG, Firecrawl, Inference Harness on .116, home stack, audiobookshelf); infrastructure-maintenance is a deliberately narrower host-level weekly pull scoped to .116 and .7.
+- `infrastructure-monitoring.prose.md` — provides the pre-update health baseline (depends_on).
+- `infrastructure-control.prose.md` — topology source of truth (CT IDs, IPs, hostnames).
+- `litellm-health.prose.md` — LiteLLM probe details.
+- `proxmox-monitor.prose.md` — Docker stats + monitoring stack health.
