# Session Handover: S-2026-0225-2016

## Where We Are

Completed the full 5-task Watchtower LXC migration pipeline (T-280 → T-284). Watchtower now runs on LXC 170 (192.168.10.170) with prod on :5050 and dev on :5051, both accessible via HTTPS FQDNs through Traefik. Swarm stack decommissioned. Pushed all commits to OneDev. Verified both prod and dev dashboards load in browser. 13 work-completed tasks from prior sessions await human browser 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 config)

## Things Tried That Failed

1. **SSH to Proxmox nodes directly** — Permission denied (publickey). Used Proxmox REST API via shared toolkit's proxmox_client.py instead
2. **First LXC creation without SSH key** — Couldn't access container. Deleted and recreated with `ssh-public-keys` parameter
3. **URL-encoding SSH key for Proxmox API** — Double-encoding broke validation. Pass raw key, 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 await human browser verification — consider batch review

## Gotchas / Warnings for Next Session

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

## Suggested First Action

Fix T-271 (budget-gate stale critical status trap) — the only real open engineering task. Alternatively, batch-close the 13 human-review tasks if already verified.

## Files Changed This Session

- Modified: deploy/traefik-routes.yml (Swarm .201/.202 → LXC .170)
