Live symptom: the radio bot shows "Listening to <system>" but is not in the
voice channel.
- Presence was set once on the first successful join and never cleared, so a
bot whose voice dropped (or whose rejoin kept failing) still looked healthy.
Presence is now synced at the end of every reconcile: set only while a voice
connection for that bot is up, cleared otherwise.
- Pre-check the bot's permissions (View Channel, Connect, Speak) and the
channel's user limit before joining. Discord silently ignores a join the bot
may not make; discord.py then times out after 30s and the admin page read
"Could not connect to the voice channel (TimeoutError: )". Now: code
missing_permissions / channel_full with the missing permission named.
- A connect timeout gets its own code (connect_timeout) and readable text.
- requirements: discord.py[voice]>=2.7 — Discord has required DAVE E2EE voice
since 2026-03-01 and 2.7 is the first discord.py with it (the extra pulls
davey). Today's resolution was already 2.7.1 + davey 0.1.6; this stops an
older resolution from ever being accepted.

- Rewritten as RadioManager reconciling C2's retained
nodes/{id}/discord/desired (token ids) and publishing
nodes/{id}/discord/actual {applied_seq, sessions, streams}.
- One gateway session per leased token, one voice connection per
(token, guild); a token no stream needs is logged OUT (client.close()),
which is what lets C2 free it safely (item 1).
- Watchdog is a separate reconcile loop; recovering a dead session can no
longer cancel it (item 2). Presence kept across rejoins.
- No message-content intent and no @bot leave/join mention controls (item 3).
- Local dashboard: /api/discord/join returns 409 with an explanation instead
of a TypeError 500; /api/discord/leave pauses locally; GET /api/discord
shows state (item 4). Join/leave results are reported to C2 (item 5).
- Token strings fetched over HTTPS from C2 (lease holder only), memory only.
- MQTT-loss fail-safe: logs every bot out after
DISCORD_MQTT_LOSS_STOP_SECONDS (300, below C2's 600s lease grace).
- Legacy discord_join/discord_leave MQTT commands are ignored.
- Audio path unchanged: FFmpeg -f pulse on settings.pulse_source per
connection, never Icecast.

Pure formatting, no behaviour change: strip trailing whitespace from blank
lines, give top-level defs in system_cacher.py their two blank lines, wrap
the long discord_radio.join signature, and split the duplicated
active_config ternary in main.py and routers/api.py across lines.
Verified clean with flake8 --max-line-length=120, matching CI.

- RadioBot.join() accepts system_name parameter
- Sets bot activity to ActivityType.listening → system name on connect
- Clears presence (activity=None) on leave
- main.py passes system_name from MQTT payload to radio_bot.join()
docker-compose.yml: Added a pulse_socket named volume mounted at /run/pulse in both op25 and edge-node. Also set PULSE_SERVER=unix:/run/pulse/native in edge-node so libpulse (and ffmpeg's pulse input) finds the right socket.
discord_radio.py: Removed _icecast_url and changed _play_stream() to use -f pulse -i default.monitor. This reads directly from the PulseAudio sink monitor — zero buffer delay. The PULSE_SERVER env var is inherited by the ffmpeg subprocess.
Note: default.monitor captures whatever audio is playing on the default sink. If OP25 uses a named virtual sink, you may need to replace default.monitor with <sink_name>.monitor (run pactl list sinks short inside the op25 container to find the name).
Issue 2 — No audio URL / GCS credentials
storage.py: storage.Client() was using ADC but ADC isn't configured in the container. Now uses storage.Client.from_service_account_json(settings.gcp_credentials_path) when GCP_CREDENTIALS_PATH is set — same credential file Firebase already loads.
You also need to mount the key file into the server container in docker-compose.yml:
c2-core:
volumes:
- ./gcp-key.json:/app/gcp-key.json:ro
And set GCS_BUCKET=your-bucket-name in .env.
Issue 3 — Token orphaning
mqtt_manager.py: Every checkin now includes "discord_connected": radio_bot.is_connected.
mqtt_handler.py: On checkin, if discord_connected is explicitly False, calls release_token(node_id). Only fires on explicit false (missing field = unknown = no action).
node_sweeper.py: When a node is swept to offline, its token is released too. This covers the case where the node stops checking in entirely (crash/power loss).
