- c2-core: POST /discord/link-codes (org owner/admin) mints a single-use,
10-minute code; minting revokes the org's older codes. The bot redeems it
via POST /discord/guilds/{id}/link/redeem (service key) inside one
Firestore transaction, so two servers racing for one code cannot both win
and a server linked to org A refuses org B's code. GET/DELETE
/discord/linked-guilds lists/unlinks the caller's org's servers; unlink
stops that server's streams. Rate-limited (mint per user, redeem per
server and per Discord user); every mint/link/refusal/unlink audited.
- resolve_guild_org: an explicitly unlinked server no longer falls back to
DISCORD_UNLINKED_GUILD_ORG_ID. Linking away from the fallback org stops
the streams it had running for that org.
- Discord bot: /drb link code: (Manage Server, enforced at runtime too);
GatedTree answers every other command in an unlinked server with how to
link (autocomplete returns nothing). With the default fallback org set,
nothing is gated — unchanged behaviour.
- Frontend: "Linked Discord servers" card on Settings -> Organization —
generate code with countdown + copy, polls for the new link, unlink.
- 16 tests: single-use, two-server race, one-server/two-org race, expiry,
revoked/malformed codes, wrong-org takeover, idempotent relink, rate
limits, fallback stop, scoped list, unlink without fallback.

c2-core
- discord_streams/discord_leases wired in: POST /discord/streams,
POST /discord/guilds/{id}/stop, GET /discord/guilds/{id}/overview,
GET /discord/streams/{id}, PUT /discord/guilds/{id}/link (admin),
GET /discord/node/{node}/tokens/{id} (node key, lease holder only).
- Retained nodes/{id}/discord/desired (token ids, never token strings),
nodes/+/discord/actual subscribed and handled; per-node publish lock keeps
the retained list the newest; failed publishes retried by the reconciler.
- Tokens freed only after the node acks logout (or offline past
discord_lease_offline_release_seconds) - sweeper and C2 startup no longer
release leases.
- /nodes/{id}/command discord_join/leave map onto streams; CommandPayload
keeps preferred_token_id. /tokens: admin-only list, validate on add against
Discord, refresh, flush via transactional force release.
- Guild -> org via discord_guilds, unlinked guilds fall back to
DISCORD_UNLINKED_GUILD_ORG_ID (default "founding").
- tests/fake_firestore.py: optimistic-transaction fake; 27 lease/race tests.
discord bot
- /join, /leave, /status, autocomplete scoped to the calling guild; /leave
never touches another server; Manage Channels default permission;
/join edits its reply with the node's real result; /help copy fixed.
