Consumes the Python tracker's /ws/live firehose (subscribed to rare+chat),
classifies rares common/great, posts embeds + relays allegiance chat.
- classify.go: the 74-name common-rares set, extracted verbatim from the Python
COMMON_RARES_PATTERN (not hand-transcribed). go test runs at build time; a
server-side dump-rares vs the Python regex confirms the sets are IDENTICAL.
- poster.go: a `poster` interface with a real discordgo impl (REST sends by
channel id; gold/blue embeds, location/time fields, icon attachment) and a
dry-run log impl.
- ws.go: coder/websocket client to /ws/live with subscribe, ping keepalive,
exponential-backoff reconnect; rare/chat dispatch incl. vortex-warning + the
MONITOR_CHARACTER filter.
- SAFE BY DEFAULT: dry-run unless a token AND DRY_RUN=0 are set, so it can never
double-post to production. Deployed via the compose override
(discord-rare-monitor-go), running dry-run against the same live firehose.
Validated on the server: connects, subscribes, relays a real chat in dry-run;
classifier parity 74/74 vs the Python regex.
