oskar 1666511475 feat(kb-mail): fundament — pgvector spine, koperta, archiwum, pakiet domeny
- services/kb-postgres: pgvector/pgvector:pg16 na SOLARIA (:5433), named
  volume, init/001_envelope.sql (CREATE EXTENSION vector + zamrożona tabela
  envelope: id/source/ts/geo/raw_ref/entities), service.yaml, healthcheck,
  README z poprawnym mechanizmem deploy (deploy-node.sh składa dwa -f)
- hosts/solaria/runtime/kb-postgres/docker-compose.override.yml: mem_limit 4g
- inventory/topology.yaml + hosts/solaria/services.yaml: kb-postgres wpisany
- packages/kb-mail: nowa konwencja shared lib (pip install /repo/packages/<lib>/)
  envelope.py — @dataclass Envelope, walidacja tz-aware ts
  db.py       — insert_envelope / get_envelope (asyncpg, ON CONFLICT DO NOTHING)
  archive.py  — save_eml append-only (asyncio.to_thread, FileExistsError na dup)
  tests: 15 unit pass + 5 integration (@pytest.mark.integration, wymaga KB_TEST_DSN)

Oskar Kapala 01b7758fe6 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
