# Session Handover: S-2026-0225-2007

## Where We Are

Completed the full 5-task LXC migration pipeline for Watchtower (T-280 through T-284). Watchtower is now running on LXC 170 (192.168.10.170) with prod on :5050 and dev on :5051, accessible via HTTPS FQDNs through Traefik. The Swarm stack has been decommissioned. 13 work-completed tasks from prior sessions remain in active/ awaiting human verification.

## Inception Phases

**1 inception task(s) pending decision** — run `fw inception status` for details.

## Gaps Register

**2 spec-reality gap(s) being watched** — see `.context/project/gaps.yaml`

- **G-004** [low]: Multi-agent collaboration untested
- **G-011** [low]: PostToolUse hooks are advisory-only — cannot block actions

Run `fw audit` to check if any trigger conditions are met.

## Decisions Made This Session

1. **D-040: systemd timer over OneDev webhook for dev auto-update (T-283)**
   - Why: Simpler (no webhook endpoint to configure/secure on LXC), integrates with systemd logging
   - Alternatives rejected: OneDev webhook (requires HTTP endpoint, auth, firewall)

## Things Tried That Failed

1. **SSH to Proxmox nodes directly** — Permission denied (publickey). Used Proxmox REST API instead via the shared toolkit's proxmox_client.py
2. **SSH to new LXC without key** — First LXC creation didn't include SSH key. Deleted and recreated with `ssh-public-keys` parameter
3. **URL-encoding SSH key for Proxmox API** — Double-encoding broke validation. Pass raw key and let requests handle encoding
4. **Registry image deletion** — Registry doesn't have delete enabled. Images left in place (inert)

## Open Questions / Blockers

1. 13 work-completed tasks in active/ awaiting human browser verification — consider a batch review session

## Gotchas / Warnings for Next Session

- Proxmox nodes (.180/.185/.190/.195) don't accept SSH from this machine — use the API client at `/opt/claude-shared-toolkit/skills/proxmox/proxmox_client.py`
- LXC 170 uses Debian 13 with Python 3.13.5 (not 3.12) — all deps work but note the version
- Docker registry at .201:5000 still has watchtower images (can't delete, harmless)
- The dev auto-update timer runs every 5 min — after pushing to OneDev, wait up to 5 min for dev FQDN to reflect changes

## Suggested First Action

Push latest commits to OneDev (`git push onedev master`) — this session's 5 commits haven't been pushed yet, and the dev auto-update timer on the LXC needs them to sync.

## Files Changed This Session

- Modified: deploy/traefik-routes.yml (Swarm → LXC IPs)
- Modified: deploy/docker-compose.swarm.yml (marked SUPERSEDED)
- Modified: Dockerfile (marked SUPERSEDED)
- Created: .context/episodic/T-280.yaml, T-281.yaml, T-282.yaml, T-283.yaml, T-284.yaml
- Completed: T-280, T-282, T-283, T-284 (moved to .tasks/completed/)

## Recent Commits

- 70c12f3 T-284: Decommission Swarm watchtower stack — LXC is now the sole deployment
- d44da6d T-283: Dev auto-update — systemd timer polls every 5 min, pulls + restarts on changes
- 7e41f03 T-282: Remap Traefik routes from Swarm (.201/.202) to LXC (.170)
- 108a5a7 T-281: Deploy Watchtower to LXC — dev (:5051) and prod (:5050) services running
- 0a75b6d T-280: Provision Watchtower LXC on proxmox2 (CT 170, Debian 13, 192.168.10.170)
