fix: recover from 2026-07-12 power-event fallout + efficiency cleanup

Browse Source 
- gitea: LevelDB queues -> local /var/lib/gitea-queues (stale NFS lock, 7,972-restart loop)
- semaphore-db: data -> local /var/lib/semaphore-db (stale ibdata1 NFS lock, 975 restarts)
- sonarr: config -> local /var/lib/sonarr (SQLite-on-NFS migration crash)
- nzbhydra2: mem_limit 768M -> 1G (was pinned at limit, unhealthy)
- jellyfin: deploy pending VAAPI device passthrough (i965/renderD128)
- openvas: disable Watchtower (latest major pull forced pg_upgrade crash-loop)
- onyx: fully decommissioned (down since ~June 8 unnoticed)
- remove duplicate monitoring/traefik/guacamole stacks from .100, failover guacamole from bart
- synapse: raise rc_message (alertmanager receiver was 429-limited; alerts silently dropped for weeks)
- prometheus: UniFi probe 8443 -> 11443, solo.hobbs.farm via 401-tolerant module, drop onyx target
- frigate restart cron: unwritable /var/log path meant it never ran; now 4x daily to ~glyptic
- CLAUDE.md: document all of the above + AdGuard broken/unconfigured since 2026-05-17

9. **Guacamole schema**: App image pinned to `guacamole/guacamole:1.6.0` + `guacd:1.6.0` with Watchtower disabled. DB schema was reset to fresh 1.6.0 on 2026-05-20 (old schema was non-standard). Recreate connections after any DB reset.
10. **Gitea image**: Pinned to `gitea/gitea:1.26.1` with Watchtower disabled (2026-05-20). Watchtower previously pulled broken `:latest` images causing missing git binary errors.
11. **Home Assistant reverse proxy**: Config at `/mnt/docker-data/configs/homeassistant/configuration.yaml` (no hyphen). Must have `http: use_x_forwarded_for: true` + `trusted_proxies: [172.16.0.0/12, 127.0.0.1]` or proxied requests return 400.
12. **hf-pdocker-01 memory pressure (2026-07-05, retrimmed 2026-07-11)**: Node runs hot (~15-18/23GB, chronic swap). Mitigations applied: `vm.swappiness` lowered 60→10 (persisted in `/etc/sysctl.d/99-swappiness.conf`), and VoiceCoach (v1+v2, ~10 containers) fully removed (replaced by FRIDAY Voice on .150). Frigate is the main consumer. **2026-07-11:** Frigate's built-in AI features (`semantic_search: large`, `face_recognition`, `lpr`, `classification.bird`) were found *enabled* (contradicting the intended baseline) and re-disabled — dropped the embeddings CLIP model ~1.2GB→168MB and cut CPU inference; host mem 18→~9GB, swap 3.9→1.3GB right after. Config `/mnt/docker-data/configs/frigate/config/config.yml` (backup `.bak.20260711-aitrim`). Recognition is instead handled externally by clip-service + frigate-notify v2. NOTE: recording ffmpeg processes still leak 4-14GB over hours (daily 4am restart-frigate cron mitigates); `memswap_limit` is 16G.

Config `/mnt/docker-data/configs/frigate/config/config.yml` (backup `.bak.20260711-aitrim`). Recognition is instead handled externally by clip-service + frigate-notify v2. **2026-07-12 — WHOLE-NODE CRASH:** .192 froze hard (~14:15, sshd/HA/DNS all dead, required hard reboot). Cause: Frigate `memswap_limit` had drifted to **16G** vs `mem_limit` 12G, letting it spill ~4GB into host swap; with the ffmpeg leak pinning it at 12G all day (cgroup OOM every ~45min), the host swap-thrashed to death. **Fix: node compose `memswap_limit: 12G` (= mem_limit) so Frigate can never use host swap** — a hit now trims its own ffmpeg (contained cgroup OOM), not the host. Repo already had 12G; node had drifted (never redeployed). NOTE: recording ffmpeg still leaks ~0.8GB/h atop ~6GB baseline (fills 12G in ~7.5h); twice-daily 4am+4pm restart-frigate cron mitigates but doesn't fully beat it — consider every-6h restart + fixing broken cameras (gate_camera, garage_2). Always keep `memswap_limit == mem_limit` on this node.
13. **Docker Desktop vs UniFi OS Server pipe conflict (Windows box .150, 2026-07-05)**: Both fight over `\\.\pipe\docker_engine`; Docker Desktop's backend nil-panics ("backend exited before becoming ready") if Podman wins. Fix: let Docker Desktop (auto-starts at login) claim the pipe first, launch UniFi OS Server manually after. Full detail in memory `docker-desktop-unifi-podman-conflict`.
14. **MySQL InnoDB corruption on NFS**: `semaphore-db` (mysql:8.0 on NFS) hit system-tablespace page corruption and crash-looped 3789× (2026-07-11), same class as the Guacamole-on-NFS issue (#9). Recovered in-place via `--innodb-force-recovery=1` → mysqldump → fresh volume → reimport (DB was empty, no data lost); admin recreated with `semaphore user add`. Any MySQL DB on NFS is at risk — prefer LOCAL storage like guacamole-db. See memory `semaphore-db-nfs-corruption`.
15. **litellm hangs after DB blip**: litellm does NOT self-recover from a transient `litellm-db` disconnect — it loops on "Prisma DB reconnect failed" forever; needs manual `docker restart litellm`. Its healthcheck was fixed from `curl` (absent from image, permanent false-unhealthy) to a python urllib check (2026-07-11).
16. **Stale NFS locks after unclean reboot/power loss (2026-07-12 power event)**: NFS file locks held by pre-reboot client identities survive on the Synology and block relocking — gitea crash-looped 7,972× on its LevelDB queue lock, semaphore-db 975× on `ibdata1`. Fix applied 2026-07-13: lock-prone data moved to LOCAL disk (gitea queues → `/var/lib/gitea-queues`, semaphore-db → `/var/lib/semaphore-db` on .100; sonarr config → `/var/lib/sonarr` on bart). **Rule: anything holding long-lived file locks (MySQL, SQLite, LevelDB) goes on local disk, never NFS.**
17. **Synapse rate-limited Alertmanager notifications**: default `rc_message` (0.2 msg/s) made every matrix-alertmanager-receiver send fail with M_LIMIT_EXCEEDED 429 — **no alerts reached Matrix for weeks** while outages accumulated (Onyx down 5 weeks, AdGuard dead 2 months, unnoticed). Fixed 2026-07-13: `rc_message: {per_second: 5, burst_count: 50}` in homeserver.yaml (backup `.bak-20260713-ratelimit`).
18. **AdGuard Home unconfigured since 2026-05-17**: its conf dir (`/mnt/docker-data/configs/adguardhome/conf`) is empty — container runs the first-launch wizard and serves NO DNS. No AdGuardHome.yaml backup exists anywhere. LAN DNS has been coming from elsewhere (router) since May. Needs manual re-setup at http://192.168.86.192:3000.
19. **Duplicate failover stacks removed from .100 and bart (2026-07-13)**: .100 ran a second monitoring stack (prometheus/grafana/alertmanager/influxdb/blackbox), an idle traefik (shared acme.json with .192 — ACME conflict risk), and a stray guacamole; bart ran a failover guacamole. All removed (~2GB RAM reclaimed). Compose dirs kept for reference; data volumes untouched.
20. **UniFi OS Server probe port**: `unifi-os-server` on .100 serves HTTPS on host port **11443** (container 443), not 8443. Blackbox probe fixed 2026-07-13. solo.hobbs.farm returns 401 (Traefik basicAuth) when healthy — probed via `http_2xx_or_401` module.
