+- CouchDB: :5984 -- Obsidian LiveSync backend. DB `secondbrain`; admin creds in Vaultwarden ("CouchDB - Obsidian LiveSync"). LAN-only (no Traefik route). Data on LOCAL disk `/var/lib/couchdb` (NFS breaks CouchDB file locking). **`local.ini` must be mounted READ-WRITE** -- with `:ro` CouchDB exits 1 and logs nothing. Auth required on everything except `/_up` (left open for the blackbox probe). Vault repo: git.hobbs.farm/jeremy/second-brain (private); vault lives at `C:\Users\Jeremy\second-brain` on the Windows box.

 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.

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).

+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.
 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).
