Emi Griffith	64b4eae217	daemon: let the conversational agent own @mentions in server channels ... THERMOGRAPH_DISCORD_BOT_MENTIONS=0 makes the gateway bot silent on guild mentions. Default on, and unset counts as on, so every env file that predates the knob behaves exactly as before. The reason is a second responder. The operator's desktop now runs a conversational agent that replies as this same bot account (discord-voice-bot, AGENTS.md) and grades through the same API we do, so with both live a single "@Thermograph Phoenix" gets answered twice — once as a card, once as a reply. Only one of us can own that surface, and the agent is the one that can also hold a conversation. Scoped to guild mentions on purpose. DMs stay here: the agent polls guild channels only, so staying silent in a DM would just drop the message. And /grade is a signed HTTP interaction that never touched this path, so it keeps answering from prod while the desktop is asleep — which is what stops this from trading an always-on surface for a sometimes-on one.

emi	2d3f37c474	daemon: move the Discord gateway and scheduler out of the web process into Go (#21) ... The gateway bot and APScheduler were long-lived stateful I/O loops running inside the async web app under a leader election. They move into a single Go binary that owns ONLY that I/O -- websocket, RESUME, heartbeat, backoff, timers. It owns no grading logic. Anything needing data calls back over a new internal-only surface (/internal/discord/grade, /internal/jobs/*). Grading depends on polars and the parquet cache; reimplementing it in Go would let the bot's grades drift from the API's. The grade route returns gateway-ready JSON and Go relays the bytes verbatim. The binary ships in the backend image and runs as a second compose service off the same tag, so the two ends of the /internal/* contract can never skew. deploy.sh rolls daemon alongside backend -- without that the service would never be created, since a single-service deploy uses --no-deps. It also probes the image first and skips the daemon when rolling a tag that predates the binary: infra tracks main while image tags are env-staged, so a host can legitimately be asked to roll an older backend image, and creating the service anyway would leave a container crash-looping on a missing binary. replicas: 1 with order: stop-first replaces the leader election -- Discord permits one gateway connection per bot token. THERMOGRAPH_INTERNAL_TOKEN is optional: both ends derive it from THERMOGRAPH_AUTH_SECRET via HMAC under a domain-separation label, so this needs no new vault entry. The derivation is pinned to a shared cross-language test vector asserted on both sides, so drift fails CI instead of 401ing every call. Fail closed when neither secret is set. Improvements over the Python: a close intended for RESUME uses 4000 rather than 1000 (Discord invalidates a session closed 1000, so the old default defeated its own resume); MESSAGE_CREATE runs on a bounded worker pool; and a malformed HELLO returns an error rather than a clean reconnect, which would otherwise reset backoff and hot-loop against the gateway. 365 Python tests pass; Go build/vet/test -race clean; shellcheck 0 findings.	2026-07-23 22:49:54 +00:00
