fix: voice_recognition uses constants for credentials and paths

The cog did its own netrc read from a hardcoded /home/pi/.netrc at import
time, crashing on any other host. Now:

- constants.py: ASSEMBLYAI_API_KEY resolved like every other token
  (env ASSEMBLYAI_API_KEY -> netrc machine 'assemblyai' at
  CONJURER_NETRC_FILE); new TRANSCRIPTS_PATH (env
  CONJURER_TRANSCRIPTS_PATH, defaults next to the log file, created by the
  runtime layout)
- voice_recognition_commands.py: drop the hardcoded netrc read and
  transcript dir; when the key is missing raise a clear RuntimeError so
  the guarded loader disables ONLY this cog with a readable reason
- bot.env.example: document ASSEMBLYAI_API_KEY

 """
 Module of a python bot named Conjurer - used to work on BDSM discord servers.
+
+Startup is defensive by design:
+
+* every cog is loaded independently - one broken/missing dependency disables
+  that cog only, never the whole bot,
+* cogs that need a sibling service (musician / librarian) are only enabled
+  after a positive health check; a watchdog keeps re-checking and enables them
+  the moment the service comes alive,
+* fatal misconfiguration (missing Discord token) exits loudly on stderr with a
+  clear message instead of dying silently into a log file.

+| **Librarian** | VM-librarian | `conjurer-librarian` | 5001 | `docker/Dockerfile.librarian` |
+| **Musician** | VM-musician | `conjurer-musician` | 5000 (+ radio) | `docker/Dockerfile.musician` |
+
+The three talk to each other over HTTP on the Proxmox LAN. Direction of calls:
+
+```
+   bot  --(/mp3,/get_music,/add_to_priority,...)-->  musician
+   bot  --(/query)-------------------------------->  librarian
+musician --(/prepped_tracks)-------------------->    bot
+librarian --(/conjurer results)----------------->    bot
+```
+
+Everything is configured through `CONJURER_*` environment variables (see the
+`docker/env/*.env.example` files). Nothing is hardcoded to a host path anymore.
+
+---
+
+## 0. Prerequisites (per VM)
+
+Create a small Linux VM in Proxmox (Debian 12 / Ubuntu 22.04+ is fine), then
+install Docker:
+
+```bash
+sudo apt-get update && sudo apt-get install -y ca-certificates curl git
+curl -fsSL https://get.docker.com | sh
+sudo usermod -aG docker "$USER"   # log out/in afterwards
+```
+
+Clone the repo on each VM (they build from it):
+
+```bash
+sudo mkdir -p /opt && cd /opt
+git clone https://github.com/migatu/conjurer.git
+cd conjurer
+```
+
+> All `docker compose` commands below are run **from the repo root** (`/opt/conjurer`),
+> because the compose files use `context: ..` relative to `docker/`.
+
+---
+
+## 1. Main bot (VM-bot)
+
+### 1a. Prepare host directories
+
+```bash
+sudo mkdir -p /srv/conjurer/data /srv/conjurer/secrets
+```
+
+### 1b. Preserve existing command history  ⭐
+
+The bot's conversation memory and settings live in JSON files. Copy them from
+your current deployment (e.g. the Pi's `/home/pi/Conjurer/`) into the data
+volume so the history carries over:
+
+```bash
+# run on the Pi, or scp the files across, then place them here:
+sudo cp pamiec.json            /srv/conjurer/data/   # AI conversation history
+sudo cp pamiec_muzyki.json     /srv/conjurer/data/   # music-DJ memory
+sudo cp settings.json          /srv/conjurer/data/   # word/cyclic reactions
+sudo cp system_gpt_settings.json /srv/conjurer/data/
+sudo cp accident_log.json      /srv/conjurer/data/   # if present
+```
+
+If you skip this, the container starts with the (empty) template files baked
+into the image and history begins fresh.
+
+### 1c. Tokens
+
+Drop your existing netrc (the one with `discord`, `openai`, `spotipy`,
+`youtube` entries) into the secrets dir:
+
+```bash
+sudo cp ~/.netrc /srv/conjurer/secrets/.netrc
+sudo chmod 600 /srv/conjurer/secrets/.netrc
+```
+
+(Alternatively skip netrc and set `DISCORD_TOKEN` / `OPENAI_API_KEY` in the env
+file — those take precedence.)
+
+### 1d. Configure and launch
+
+```bash
+cp docker/env/bot.env.example docker/env/bot.env
+# edit docker/env/bot.env: set CONJURER_FILE_SERVICE / _LIBRARIAN_SERVICE to the
+# other VMs' IPs, and CONJURER_API_KEY (same value on all three) if you want auth.
+
+docker compose -f docker/compose.bot.yaml up -d --build
+docker logs -f conjurer-bot
+```
+
+Look for `Extension loaded: …` for each cog and `All systems: operational`.
+
+### 1e. Startup model: core cogs vs service-gated cogs
+
+The bot **always** starts with the cogs that depend on nothing but itself
+(administration, AI, other, latex, voice, conanjurer). Cogs that need a
+sibling service are **health-gated**:
+
+| Group | Cogs | Enabled when |
+|-------|------|--------------|
+| musician | `music_commands`, `radio_commands`, `file_search_commands` | `GET {FILE_SERVICE}/mp3` answers |
+| librarian | `librarian_commands` | librarian answers HTTP at all |
+
+When a service is down its cogs stay disabled (commands simply don't exist)
+and the log says so. A watchdog re-checks every 5 minutes and enables the
+cogs the moment the service starts answering — no bot restart needed.
+A single broken cog (missing pip package, bad import) is skipped with a full
+traceback in the log; it never takes the whole bot down.
+
+### 1f. Troubleshooting a crash-looping container
+
+`docker logs conjurer-bot` now shows the real reason (the bot logs to stdout
+as well as the rotating file). The most common cases:
+
+- **`FATAL: Discord token missing`** — the secrets mount is missing/empty or
+  `CONJURER_NETRC_FILE` points elsewhere. Check:
+  `docker inspect -f '{{json .Mounts}}' conjurer-bot | jq` and
+  `docker exec conjurer-bot ls -la /secrets/` (after a manual
+  `docker run … sleep infinity` if it crash-loops too fast).
+- **Missing state files** — not fatal anymore: missing dirs are created and
+  missing JSON state is seeded from the repo templates baked into the image
+  (existing files are never overwritten). Fix the mount at your leisure.
+
+**About files "disappearing" from `/srv/conjurer/...`:** nothing in this stack
+deletes host files — the entrypoint and the bot only ever *create* missing
+files. With a bind mount, `/srv/conjurer/data` **is** the live state (not an
+installation staging area): don't delete it after a successful install.
+If files vanished, the usual suspects are `docker compose down -v` (only
+affects *named* volumes, not binds), a re-provisioned VM, or copying the files
+to a different path than the one in the compose `volumes:` line — verify with
+`docker inspect -f '{{json .Mounts}}' conjurer-bot`.
+
+---
+
+## 2. Librarian (VM-librarian)
+
+### 2a. Mount the DOI database
+
+The librarian checks keyword hits from Crossref against a local database of
+DOI chunk files (`0_chunk.txt … N_chunk.txt`). Put that database on the VM and
+point the volume at it:
+
+```bash
+sudo mkdir -p /srv/librarian/doi /srv/librarian/secrets
+# copy/replicate your chunk files into /srv/librarian/doi/
+```
+
+> The old Windows path `C:\Database\chunks\` is now `CONJURER_LIBRARIAN_DB_PATH`
+> (defaults to `/doi/` in the container). `CONJURER_LIBRARIAN_MAXTHREADS` (41)
+> and `CONJURER_LIBRARIAN_CHUNK` (`_chunk.txt`) are configurable too.
+
+### 2b. Configure and launch
+
+```bash
+cp docker/env/librarian.env.example docker/env/librarian.env
+# edit: CONJURER_MAIN_BOT=http://BOT_VM_IP:5000, CONJURER_CROSSREF_MAILTO, CONJURER_API_KEY
+
+docker compose -f docker/compose.librarian.yaml up -d --build
+docker logs -f conjurer-librarian
+```
+
+---
+
+## 3. Musician (VM-musician)
+
+The web service is container-ready (`docker/Dockerfile.musician` +
+`compose.musician.yaml`). It containerises the **Flask file/playlist service
+only** — the Liquidsoap radio (`radio_conjurer.liq`), `script.params` and any
+Samba/NFS share tooling are separate and typically stay on the host or a
+dedicated setup (you'll adapt those yourself).
+
+### 3a. Two volumes: the library and the writable state
+
+| Mount | Container path | Holds |
+|-------|---------------|-------|
+| `/srv/musician/music` | `/music` (`CONJURER_MUSIC_FOLDER`) | your mp3 library (indexed/served) |
+| `/srv/musician/data` | `/data` (`CONJURER_MUSICIAN_BASE`) | playlists, logs, `radio_log.log`/`persistence.log` |
+
+```bash
+sudo mkdir -p /srv/musician/music /srv/musician/data
+# point /srv/musician/music at (or copy in) your mp3s
+```
+
+### 3b. Preserve existing playlists/state (optional)
+
+If you already run the musician, copy its working playlists into the data
+volume so nothing is regenerated from scratch:
+
+```bash
+sudo cp all_playlist.playlist hit.playlist request.playlist \
+        priority_queue.playlist playlist.json  /srv/musician/data/ 2>/dev/null || true
+```
+
+The container's entrypoint (`docker/entrypoint.musician.sh`) creates any
+missing playlists and touches `radio_log.log` / `persistence.log` empty so the
+track-forwarding thread waits instead of crashing when the radio runs
+elsewhere. It never overwrites files you copied in.
+
+### 3c. Configure and launch
+
+```bash
+cp docker/env/musician.env.example docker/env/musician.env
+# edit: CONJURER_MAIN_BOT=http://BOT_VM_IP:5000 and CONJURER_API_KEY (match the bot)
+
+docker compose -f docker/compose.musician.yaml up -d --build
+docker logs -f conjurer-musician
+```
+
+### 3d. Radio coupling (if you keep Liquidsoap separate)
+
+The musician only forwards "now playing" to the bot by tailing the radio's
+`radio_log.log` / `persistence.log`. To wire them up, have Liquidsoap write
+those two files into the same `/srv/musician/data` directory (or set
+`CONJURER_RADIO_LOG` / `CONJURER_PERSISTENCE_LOG` to wherever it writes). The
+`/stream` page template is served from the baked-in `/app/stream.html`
+(override with `CONJURER_STREAM_TEMPLATE` if you customise it).
+
+---
+
+## 4. Networking & auth
+
+- Open the ports between VMs on the Proxmox LAN: **bot 5000**, **librarian 5001**,
+  **musician 5000** (+ radio harbor 54321 if used). A simple `ufw allow from
+  <lan-subnet>` per port is enough; do not expose them to the internet.
+- **Auth:** set the same `CONJURER_API_KEY` in all three `*.env` files. Then
+  every internal call carries `X-Conjurer-Api-Key` and each service rejects
+  requests without it (HTTP 401). Leave it empty everywhere to disable auth
+  (fully backward compatible). ⚠️ Setting it on only one side breaks the link.
+- The addresses point at each other by VM IP (or a DNS name). Set:
+  - bot: `CONJURER_FILE_SERVICE`, `CONJURER_RADIO_HARBOR`, `CONJURER_LIBRARIAN_SERVICE`
+  - librarian & musician: `CONJURER_MAIN_BOT`
+
+---
+
+## 5. Verify
+
+```bash
+# bot is up and reachable from another VM:
+curl http://BOT_VM_IP:5000/conjurer            # -> "ALIVE"
+# librarian answers:
+curl http://LIBRARIAN_VM_IP:5001/ -I           # service reachable
+docker ps            # all containers "Up"
+docker logs conjurer-bot --tail 50
+```
+
+In Discord, exercise a command that round-trips through a service (e.g. a music
+search that hits the musician, or a librarian query) to confirm the wiring and
+the API key.
+
+---
+
+## 6. Updates
+
+```bash
+cd /opt/conjurer && git pull
+docker compose -f docker/compose.bot.yaml up -d --build   # rebuild + restart
+```
+
+Data in `/srv/.../data` and `/doi` / `/music` volumes survives rebuilds, so
+history and databases persist across updates.
+
+---
+
+## 7. Rollback / coexistence
+
+- The native (Raspberry Pi / systemd) deployment is unaffected — none of the
+  defaults changed; the container behaviour is opt-in via `CONJURER_DATA_DIR`
+  and the other env vars. You can run both during migration.
+- To roll back a VM: `docker compose -f docker/compose.<svc>.yaml down` and
+  restart the previous deployment. The JSON state in `/srv/.../data` is plain
+  files you can copy back to the Pi if needed.
+
+---
+
+## Notes on the images
+
+- **Bot** uses the vendored `yt_dlp/` and `spotify_dl/` forks (they win over the
+  pip packages because `/app` is first on `sys.path`), so your patches stay
+  active without the old `sed` hacks from `install_main_bot.sh`.
+- **Tectonic** (LaTeX `$latex` command) is installed best-effort; if the build
+  step fails the bot still runs, just without LaTeX. Remove that layer from
+  `Dockerfile.bot` if you don't need it.
+- Voice needs `ffmpeg` + `libopus0` (both in the image). No microphone/pyaudio
+  is required — voice is received over Discord and transcribed via AssemblyAI.
