- 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.

Trip-level tags: admins configure available tags in the trip header (inline add/remove pills). The AI can also create new tags via the add_tag tool.
Event tags: selectable in the Add Event modal, shown as colored pills on event cards in the timeline, and on AI suggestion cards.
AI integration: sees available tags in its system prompt, applies them when proposing events, can create new ones with add_tag.
Discord: tags shown as inline code blocks under each event in /trip view.
Colors: auto-assigned from an 8-color palette by tag index, consistent everywhere.
auth.py
secrets.compare_digest replaces == for service key comparison (timing-safe)
Added require_service_key — bot-only endpoints (trip/event join/leave)
Added require_service_key_or_admin — node commands/config (bot via service key OR dashboard admin via Firebase)
Added _RateLimiter with three shared instances: trip_chat_limiter (20/5min per user), summarize_limiter (5/10min per incident), bootstrap_limiter (2/hr per system)
nodes.py
send_command and assign_system now require require_service_key_or_admin — the Discord bot can still call them via service key, but regular Firebase users are blocked
tokens.py
add_token, flush_tokens, set_preferred_system, delete_token all require require_admin_token
Token masking changed from token[:10] + "…" + token[-4:] to "•••" + token[-4:]
systems.py
All write endpoints (create, update, delete, ai-flags, ten-codes, vocabulary writes, bootstrap) now require require_admin_token
bootstrap_vocabulary also calls bootstrap_limiter.check(system_id)
incidents.py
POST /incidents/summarize (bulk) now requires require_admin_token
POST /incidents/{id}/summarize now calls summarize_limiter.check(incident_id)
trips.py
join_trip, leave_trip, join_event, leave_event require require_service_key — only the Discord bot can set Discord attendee identity
delete_trip, delete_event require require_service_key_or_admin
trip_chat rate-limited per caller UID, history stripped to user/assistant roles only, user message truncated to 2000 chars, Maps query strings capped at 200 chars
upload.py
Rejects files larger than settings.upload_max_bytes (default 100MB) with 413
storage.py
_safe_audio_filename() derives GCS object name from call_id + allowlisted extension, completely ignoring the client-supplied filename
config.py
Added upload_max_bytes: int = 100 * 1024 * 1024
Both Dockerfiles — python:3.14-slim → python:3.12-slim
New /trips router with full CRUD, attendee management, and nested
events. Events validate date is within parent trip range and inherit
trip location when not explicitly set. Leaving a trip cascades
removal from all its events.
New TripCommands cog with /trip create, list, view, delete, join,
leave and /trip event add, remove, join, leave. Event autocomplete
is scoped to the selected trip. Enforces must-be-on-trip rule for
event joins with a clear error message.
