An org owner links a server by inviting one radio bot through that bot's
own OAuth2 invite (owner decision Q1). The state is a single-use, 10-minute
nonce bound to org + user (stored only as its sha256); the server linked is
the one Discord's code exchange names, never the redirect query.
- routers/discord_oauth.py: GET /discord/oauth/options, POST /start,
POST /complete. 404 while discord_oauth_redirect_uri is empty or no
usable bot has a secret. Bot order: explicit token_id, the node system's
preferred bot, the org's own bot, least-full pool bot under the cap.
- internal/discord_oauth.py: state mint/consume transaction (login-CSRF:
state.uid must be the caller; any presentation burns it), code exchange,
revoke, client-credentials secret check. Through discord_rest's shared
client and breaker; secrets/codes/tokens never logged or in errors.
- discord_guild_link: one link transaction body (_apply_link) and one
settle step that stops a server's streams when the org it acted for
changes (plan finding 3). /drb link redeem, the admin PUT link and OAuth
all use it; the previous org is now read inside the link transaction.
- tokens: GET /tokens is an allowlist (+ oauth_enabled, server_count,
server_cap); PUT/DELETE /tokens/{id}/oauth (admin) checks the secret with
Discord before storing it in bot_oauth/{id}, never echoes it.
- firestore.rules: explicit deny for bot_oauth and discord_oauth_states.

Node-page picker and the admin Add form now show, per voice channel, whether
a radio bot can stream there, from S3's voice-check routes:
- Badge per channel: Ready / Needs fix (names the missing permission) /
Couldn't check / Bots busy / No radio bot / Not a voice channel / Limit N.
- The chosen channel shows "<bot> can't Speak in #dispatch: <what removed it>"
plus c2-core's fix sentence, and an expandable per-bot list.
- Footer: "Permissions checked 40s ago · Re-check" (refresh=1, rate limited
server-side; a limited re-check says so). Invite links when no bot fits.
- Start is disabled only on a definite refusal (needs_fix, bad_channel);
unknown fails open. A channel this system already plays in is judged by
the bot that carries it, so Update/move is never blocked by the other bots.
- Admin Add form disables bots that are definitely denied in the bot list.
- 409 refusals (missing_permissions, preferred_busy, preferred_other_node,
bad_channel) are shown verbatim, multi-line.
Org owners (owner decision Q2) get "Radio bot per system" on
Settings > Organization: their own systems, their own BYO bots, set/clear
through S3's PUT /tokens/{id}/prefer/{system}. New GET /tokens/org/preferred
lists only the caller org's systems and bots (no pool bots, no token
strings; a pool bot an admin chose is flagged, not named).
The prefer route now drops the 5-minute doc_get_cached entry for every
system it rewrites, so a new preference applies to the next start.
Stacked on feat/225-s3-perm-check: must merge after S3.

start_stream now asks Discord (cached REST snapshots, S2) whether each bot
it could pick may View, Connect and Speak in the voice channel, before the
lease. Covers all four entry points: bot POST /discord/streams, web picker,
nodes discord_join, and the reconciler's re-place.
- pick_token: denied bots skipped; confirmed-ok sorts before unknown;
unknown is allowed (fail open); all denied -> missing_permissions naming
each bot, missing permission, trace reason and fix. The reuse branch
falls through when its token is denied.
- Bounded: discord_perm_check_concurrency at once, within
discord_perm_check_budget_seconds; unanswered = unknown.
- Non-voice channel -> 400 bad_channel (not missing_permissions).
- systems/{id}.preferred_token_id is now read (plan finding 1), as a hint.
- Pool bots at discord_pool_bot_guild_cap are never offered as invites;
pool_full when nothing else is left (owner Q3).
- handle_actual drops cached access on missing_permissions, channel_full,
not_in_guild, bad_channel.
- New GET /discord/nodes/{node_id}/guilds/{guild_id}/voice-check (org
member, names only) and GET /discord/guilds/{guild_id}/voice-check
(service key or admin).
- PUT /tokens/{id}/prefer/{system_id}: org owners for their own systems
and own BYO bots; shared systems and pool bots stay admin-only (owner Q2).
Keeps both pointers single-valued; audited.
- Kill switch: DISCORD_PERM_CHECK_ENABLED=false.
- tests/conftest.py: autouse fixture so no test ever reaches discord.com.

New app/internal/discord_rest.py: one shared httpx client with the
DiscordBot User-Agent, per-token rate-limit buckets (X-RateLimit-Bucket +
guild), one retry on a 429 of <=3s, global-429 pause per token, and a
process-wide breaker at 4000 401/403/unshared-429 responses per 10 min so
C2 can never get the shared egress IP banned. Tokens are never logged.
inspect_token / refresh_membership / leave_guild / TokenRejected move off
discord_leases onto it. /users/@me/guilds now follows after= pages (it read
one page of 200 and silently dropped the rest); a failed page is unknown,
never a truncated list.
guild_snapshot(token_doc, guild_id): cached, single-flight read of
/guilds/{g}, the bot's own member and /channels for S3's permission check.
401 marks the token invalid; 10004/10007 drop the server from guild_ids;
50001 is confirmed with one membership read and never changes guild_ids
on its own. TTLs: ok 120s, not-member/invalid 600s, unknown 30s.
config.py gets every setting the #225 slices use (perm-check kill switch,
TTLs, breaker budget, OAuth redirect URI, discord_pool_bot_guild_cap=90).
No behaviour change beyond pagination, User-Agent and the breaker.

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.

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
Correlator
- Raise fast-path idle gate 30 → 90 min (tg_fast_path_idle_minutes)
- Fix disambiguate always-commits bug: run _call_fits_incident on winner
before committing; fall through to new-incident creation if it fails
- Add unit-continuity path (path 1.5): matches all_active by shared unit
IDs with a reassignment guard, bridges calls past the idle gate
- Add tag-based incident_type inference (_TAG_TYPE_HINTS) as GPT fallback,
rescuing tagged calls that would have been dropped (616 observed orphans)
- Add master/child incident model: _create_master_incident, _demote_to_child,
_add_child_to_master; new incidents stamped incident_type="master"
- Add cross-system parent detection (_find_cross_system_parent): two-signal
scoring (road overlap=0.4, embedding≥0.78=0.3, proximity=0.3, threshold=0.5)
wired into create-if-new path; creates master shell on first cross-system match
- Add maybe_resolve_parent: auto-resolves master when all children close;
called from upload pipeline (LLM closure) and summarizer stale sweep
- Add signal-based auto-resolve via units_active/units_cleared tracking:
GPT now extracts cleared_units per scene; _update_incident moves units
between active/cleared lists and resolves the incident when active empties;
stored on call doc for re-correlation sweep reuse
- Add _create_incident initialization of units_active/units_cleared fields
Re-correlation sweep
- Add corr_sweep_count + MAX_SWEEP_ATTEMPTS=3: orphans get 3 attempts
then are tombstoned as corr_path="unlinked", ending the re-sweep loop
(previously hammering each orphan 29-31 times per shift)
Intelligence extraction
- Add cleared_units to GPT prompt schema and rules
- Extract and propagate cleared_units per scene; merge across scenes;
store on call doc for re-correlation sweep
Token management
- Fix token release bug: remove release_token call on discord_connected=False
in MQTT checkin (transient Discord drops were orphaning bots mid-shift)
- Add PUT /tokens/{id}/prefer/{system_id} endpoint: lock a bot token to a
system; pass _none as system_id to clear; stored bidirectionally on both
token and system documents
- discord_join handler resolves preferred_token_id from system doc and passes
system_name in MQTT payload
app/internal/storage.py Replaced make_public() + public_url with a v2 signed URL (1-year expiry, no public bucket needed)
app/main.py Releases all in-use tokens at startup — tokens from previous sessions are cleared automatically
app/routers/tokens.py Added POST /tokens/flush to force-release orphaned tokens on demand
