Per-node checkpoint now stores the last-processed event TIMESTAMP (int epoch) instead of a file path compared lexically. A file is "new" iff its timestamp (parsed from evt-<node>-<unixts>-<type>-<svc>.json, mtime fallback) exceeds the node's checkpoint; processing is ordered by timestamp, not path. Root cause (PIHA dead ~34d, 2026-07-12): a stray evt-unknown-<ts>-… file landed in events/piha/, lexically greater than every evt-piha-… name. The lexical checkpoint pinned there, so every genuinely newer piha event sorted "before" it and was skipped forever. Event backlog grew to 7344 files, last_seen frozen, shadow-read logged false SHADOW_LIVENESS_MISMATCH event=dead prom=up. - _event_ts_from_path: filename epoch, mtime fallback; NEVER returns 0 for an existing file (0 == "older than checkpoint" == the poison). - _checkpoint_ts_from_value: graceful migration of pre-fix path-string checkpoints (and the older last_processed_file format) to int epochs; unparseable → 0 (reprocess all — safe, process_event is idempotent on last_seen/world_state; bias to reprocess, never to skip). - Preserved: quarantine of bad events, observer-source re-ingest guard. - Regression tests (test_incident_lifecycle.py section 9): lexically-smaller- but-newer processed, unparseable name falls back to mtime (not wedged), ts-not-path ordering, both checkpoint-format migrations, helper units. Separate bug filed in backlog (not fixed here): ha-diag-agent emits node= "unknown" events (config.py node_name default) into another node's dir when NODE_NAME reaches the compose volume path but not the app env — the source of the poison file.

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.
