Fix pending actions: node_exporter, zigbee2mqtt, chelsty-ha monitoring
node_exporter (new service):
- Add services/node_exporter/docker-compose.yml matching solaria deployment
(network_mode: host, pid: host, /:/host:ro,rslave mount)
- Add services/node_exporter/service.yaml
zigbee2mqtt chelsty-infra override:
- Fix network_mode: host (mosquitto runs on host network, port 1883 on localhost)
- Fix volume mount: ./configuration.yaml → absolute /opt/homelab/config/zigbee2mqtt/
(secrets stay in runtime config dir, never in Git)
- Remove MQTT_USER/MQTT_PASSWORD (mosquitto uses allow_anonymous true)
- Extend healthcheck start_period to 60s (z2m takes time on first start)
chelsty-ha/services.yaml:
- Remove node-agent entry entirely (never deployed, no plans to bootstrap now)
- Keep homeassistant with monitor: false (no node-agent = no health events)
supervisor: respect monitor: false in services.yaml
- Skip action generation for services where monitor=false
- Cleans up chelsty-ha entries from action queue without removing desired-state docs

feat(node-agent): implement health monitor and safe cleanup policy
scripts/monitor/health-monitor.sh (new):
- Standalone bash health monitor: disk/RAM/CPU checks + docker container health
- Per-node-type cleanup policy enforced:
lte_node (chelsty-infra, chelsty-ha): NO cleanup, no docker ops
sd_card (piha, saturn): dangling images + containers, rate-limited once/24h
ai_node (solaria): dangling + containers + build cache, NEVER -a
standard (vps): dangling + containers + build cache + CP filesystem rotation
- VPS filesystem rotation: completed/failed actions >7d, deploy logs >30d,
events >3d AND past observer checkpoint
- Emits structured JSON events (node_health, disk_pressure, high_memory, high_cpu,
containers_not_running, healthcheck_failed)
services/node-agent/ (new):
- Python daemon (node_agent.py): same policy as bash script, Docker SDK
for container checks and cleanup, /proc for system metrics
- Optional event shipping to VPS via rsync+SSH (VPS_EVENTS_HOST env var)
- Dockerfile: python:3.11-slim + openssh-client + rsync + docker>=6.0
- docker-compose.yml: mounts docker socket, /opt/homelab, repo read-only
observer.py:
- Handle node_health: update node status + disk/mem/cpu metrics, clear disk_pressure
- Handle disk_pressure: record severity on node, clear when healthy
- Handle high_memory / high_cpu: record pressure level for correlation
supervisor.py:
- Add NO_DISK_CLEANUP_NODES = {chelsty-infra, chelsty-ha}
- reconcile() step 3: generate disk_cleanup actions for nodes with high disk pressure
- _generate_disk_cleanup_recommendation(): stable ID disk-cleanup-{node},
checks all active states, risk=guarded (operator approval required)
executor.py:
- Handle disk_cleanup action type via _execute_disk_cleanup()
- Commands come from action payload; safety gate rejects any command touching
/opt/homelab/data/, /opt/homelab/config/, /opt/homelab/state/, or rm -rf /
hosts/*/services.yaml:
- Rename stability-agent -> node-agent on piha, vps, solaria, chelsty-infra
- Add node-agent to chelsty-ha (previously missing)
- Add cleanup policy notes to LTE node comments

refactor(hosts): split chelsty monolith into chelsty-ha and chelsty-infra
- remove legacy hosts/chelsty/ monolith
- chelsty-infra: add capabilities, networking, paths, runtime (mosquitto, zigbee2mqtt, stability-agent)
- chelsty-ha: add capabilities
- align with site/node model
