R1 (critical): _prune_stopped_containers no longer calls containers.prune().
The unfiltered API call removes EVERY non-running container, ignoring
RestartPolicy and compose labels — that is what deleted ollama@solaria 19 s
after an operator `docker stop`. No filter argument can fix it (`until` filters
on creation time, not stop time). Replaced with explicit enumeration over
containers.list(all=True, filters={"status": "exited"}), skipping anything with
restart policy unless-stopped/always/on-failure or a com.docker.compose.project
label. A stopped managed service is recorded operator intent and now belongs to
the module's NEVER TOUCHED list; only one-off leftovers are removed. Dangling
image and build cache prune are unchanged.
R2 (high): _sd_card_rate_ok → _cleanup_rate_ok, applied to every cleanup-
eligible node type. ai_node and standard pruned every 60 s (1440/day, "0 MB
reclaimed" in practically every cycle) with no rate limit at all; they now share
sd_card's CLEANUP_INTERVAL_SECS (24 h) and mark the cleanup timestamp.
R3 (medium): removals are named in the log — WARNING with the container names
when the list is non-empty, INFO otherwise. The old line reported megabytes
only, which is why ollama's deletion looked identical to every no-op cycle.
Tests: services/node-agent/tests/test_safe_cleanup.py (22 cases) — the ollama
regression (exited + unless-stopped survives, prune() never called), all three
restart policies, compose-label protection, disposable-leftover removal, sweep
continues past a failed remove, WARNING-level naming, and the rate limit for
ai_node/standard/sd_card plus lte_node still doing nothing.

Homelab Codex
GitOps-lite orchestration for a distributed homelab environment.
Architecture
The homelab consists of several nodes connected via a Tailscale internal mesh.
| Host | Role | Description |
|---|---|---|
| SATURN | Primary Node | Development, orchestration, and git source of truth (commit node). |
| SOLARIA | Compute Node | GPU, inference, and heavy compute workloads. |
| PIHA | Infra Node | Core infrastructure services, automation, and monitoring. |
| VPS | Edge Node | Public ingress, reverse proxy, and edge services. |
Agent System
The homelab uses a multi-agent orchestration model with human-in-the-loop for destructive actions:
| Agent | Node | Role |
|---|---|---|
| stability-agent | all nodes | Per-node watchdog — monitors Docker, disk, Tailscale, MQTT; emits events |
| node-agent | all nodes | Publishes container health events to Redis pub/sub |
| observer | VPS | Synthesizes world state from events into /opt/homelab/world/*.json |
| supervisor | VPS | Detects drift between desired and actual state; writes pending actions |
| planner-agent | SOLARIA | LLM-powered diagnosis — listens to Redis, proposes remediation actions |
| executor | VPS | Executes actions only after operator approval |
| operator-ui + telegram-bot | VPS / PIHA | Operator reviews and approves/rejects pending actions |
Action approval flow: pending/ → operator approves → approved/ → executor runs.

Getting Started
- Standardization: Follow the Infrastructure Standards.
- Deployment: See Deployment Conventions for how to roll out changes.
- SATURN: Remember that SATURN is the only node where commits should be made.
