 ## Project N.O.M.A.D.
- 10 containers running via `start_nomad.sh` / `stop_nomad.sh`
- `/opt/project-nomad` → symlinked from `/mnt/hdd-1/project-nomad`
+- Core compose project lives at `/opt/project-nomad` → symlinked from `/mnt/hdd-1/project-nomad`
+- Main compose file: `/mnt/hdd-1/project-nomad/compose.yml`
 - Docker data-root: `/mnt/hdd-2/docker`
 - Based on Crosstalk Solutions offline survival/knowledge server
+- Current runtime is split between:
+  - the base `project-nomad` compose stack
+  - `project-nomad-managed` app containers launched/managed by the N.O.M.A.D. admin layer
+  - a few extra non-compose / non-NOMAD containers on the host
+
+## Docker Audit — 2026-05-14
+
+### Compose files found on NOMAD
+- `/mnt/hdd-1/project-nomad/compose.yml` (same project as `/opt/project-nomad/compose.yml` via symlink)
+- `/opt/newt/docker-compose.yaml`
+
+### Running containers tied directly to compose files
+**`project-nomad` compose (`/mnt/hdd-1/project-nomad/compose.yml`)**
+- `nomad_admin`
+- `nomad_mysql`
+- `nomad_redis`
+- `nomad_dozzle`
+- `nomad_disk_collector`
+- `nomad_updater`
+
+**`newt` compose (`/opt/newt/docker-compose.yaml`)**
+- `newt`
+
+### Running containers managed by Project N.O.M.A.D. itself
+These are labeled `com.docker.compose.project=project-nomad-managed` and `io.project-nomad.managed=true`, but no standalone compose files for them were found on disk during this audit.
+- `nomad_cyberchef`
+- `nomad_flatnotes`
+- `nomad_kiwix_server`
+- `nomad_kolibri`
+- `nomad_ollama`
+- `nomad_qdrant`
+
+**Operator decision (John, 2026-05-14):** this layer stays exactly as-is. It is self-maintained by Project N.O.M.A.D. Document it, but **never manually touch, rebuild, migrate, or “clean up” these containers** unless John explicitly overrides that rule.
+
+Known storage paths discovered from mounts / project storage:
+- Flatnotes data: `/opt/project-nomad/storage/flatnotes`
+- Kiwix ZIM library: `/opt/project-nomad/storage/zim`
+- Kolibri data: `/opt/project-nomad/storage/kolibri`
+- Ollama data/models: `/opt/project-nomad/storage/ollama`
+- Qdrant storage: `/opt/project-nomad/storage/qdrant`
+
+### Running containers not tied to discovered compose files
+**Likely host-managed / manually launched / app-managed elsewhere**
+
+#### `whisper` — `fedirz/faster-whisper-server:latest-cpu`
+**Operator decision (John, 2026-05-14):** this can go away. Do not preserve it as a required service, but keep enough detail here to rebuild it if removing it causes issues.
+- Purpose: ad-hoc Faster Whisper API endpoint
+- Network mode: `bridge`
+- Container IP during audit: `172.17.0.2`
+- Port publish: host `8786/tcp` → container `8000/tcp` (IPv4 and IPv6)
+- Restart policy: `unless-stopped`
+- Entrypoint: image default
+- Command:
+  - `uv run uvicorn --factory faster_whisper_server.main:create_app`
+- Environment:
+  - `WHISPER__MODEL=Systran/faster-distil-whisper-small.en`
+  - `WHISPER__INFERENCE_DEVICE=cpu`
+  - `UVICORN_HOST=0.0.0.0`
+  - `UVICORN_PORT=8000`
+- Mounts: none
+- Compose labels: none found
+- Rebuild-equivalent `docker run`:
+  ```bash
+  docker run -d \
+    --name whisper \
+    --restart unless-stopped \
+    -p 8786:8000 \
+    -e WHISPER__MODEL=Systran/faster-distil-whisper-small.en \
+    -e WHISPER__INFERENCE_DEVICE=cpu \
+    -e UVICORN_HOST=0.0.0.0 \
+    -e UVICORN_PORT=8000 \
+    fedirz/faster-whisper-server:latest-cpu \
+    uv run uvicorn --factory faster_whisper_server.main:create_app
+  ```
+
+#### `node-exporter` — `prom/node-exporter:v1.9.0`
+**Operator decision (John, 2026-05-14):** this can go away. Do not preserve it as a required service, but keep enough detail here to rebuild it if removing it causes issues.
+- Purpose: host Prometheus metrics exporter
+- Network mode: `host`
+- Restart policy: `unless-stopped`
+- Entrypoint: `/bin/node_exporter`
+- Command:
+  - `--path.procfs=/host/proc`
+  - `--path.sysfs=/host/sys`
+  - `--path.rootfs=/rootfs`
+  - `--collector.filesystem.mount-points-exclude=^/(sys|proc|dev|host|etc)($$|/)`
+- Read-only bind mounts:
+  - `/proc` → `/host/proc`
+  - `/sys` → `/host/sys`
+  - `/` → `/rootfs`
+- Compose labels: none found
+- Rebuild-equivalent `docker run`:
+  ```bash
+  docker run -d \
+    --name node-exporter \
+    --restart unless-stopped \
+    --network host \
+    -v /proc:/host/proc:ro \
+    -v /sys:/host/sys:ro \
+    -v /:/rootfs:ro \
+    prom/node-exporter:v1.9.0 \
+    --path.procfs=/host/proc \
+    --path.sysfs=/host/sys \
+    --path.rootfs=/rootfs \
+    '--collector.filesystem.mount-points-exclude=^/(sys|proc|dev|host|etc)($$|/)'
+  ```
+
+**Pelican/Wings-managed game containers**
+**Operator decision (John, 2026-05-14):** this is the game server stack. It stays. Document it; do not remove or migrate it unless John explicitly says so.

+
+These are expected to be managed by Wings/Pelican rather than a local compose file.
+
+### Dormant compose files found but not currently represented in running containers
+- None found during this audit in searched paths.
+- Search scope: `/opt`, `/srv`, `/home/fizzlepoof`, and `/mnt` for `docker-compose.yml`, `docker-compose.yaml`, `compose.yml`, and `compose.yaml`.
+
+### Decisions captured from this audit
+- Project N.O.M.A.D.-managed app containers stay exactly as-is and are **hands-off** unless John explicitly says otherwise.
+- `whisper` and `node-exporter` are not protected services; they can be removed, but their exact runtime has been documented above for rebuild/recovery.
+- Pelican/Wings-managed game containers are part of the permanent game-server stack on NOMAD and stay in place.
+
+### Safe to remove / how to restore
+#### Safe to remove now
+- `whisper`
+- `node-exporter`
+
+Removing them should not be treated as a Project N.O.M.A.D. change or a Wings/Pelican change. They are standalone host-level containers from this audit’s point of view.
+
+#### Restore checklist if removal causes trouble
+1. Confirm what broke:
+   - speech/transcription endpoint dependency → restore `whisper`
+   - Prometheus scraping / host metrics gap → restore `node-exporter`
+2. Recreate the container using the documented `docker run` command in this file.
+3. Verify it came back cleanly:
+   - `docker ps --filter name=whisper`
+   - `docker ps --filter name=node-exporter`
+   - `docker logs --tail 50 whisper`
+   - `docker logs --tail 50 node-exporter`
+4. Re-check any dependent dashboards, scrapers, or automations.
+5. If the recreated container needs to persist long-term again, document *why* before leaving it in place.
+
+#### Restore intent
+- Restore `whisper` only if something still expects a local Faster Whisper HTTP endpoint on port `8786`.
+- Restore `node-exporter` only if something still depends on host Prometheus metrics from this box.
+- Do **not** fold either one into Project N.O.M.A.D. or Wings/Pelican casually; if they come back, they come back as deliberate standalone services unless John says otherwise.
