WebSocket and EventSource put the 30-day session token into the URL,
where proxies log it. The app now gets a one-time ticket right before
connecting (POST /auth/stream-ticket, 60 s, bound to the token version);
?token= is no longer accepted for streams, non-browser clients may use
the Authorization header.
With BASE_URL set, CORS allows only that origin and WebSocket upgrades
only it or the requested host; credentials are off (no cookies exist).
Logout, ending all sessions, a new password and deactivation close all
live streams of the account; clients with a valid session reconnect
with a fresh ticket.

Phase 4 of the collaboration plan:
- The sync engine listens for DOC_SEQ in the note's realtime room and syncs
right away. Without WebSocket/SSE it long-polls /docs/{id}/changes (25 s);
after three failures it falls back to polling every 3 s and retries long
polling when the browser comes back online.
- With push or long polling the engine only syncs every 7 s while holding
leases (renewal), otherwise every 30 s as a safety net. Focusing a block
announces its lease immediately (otherwise it could take up to 30 s).
- Realtime connection: SSE counts as connected only after its first event;
a stream that stays silent for 5 s (buffering proxy) switches SSE off for
the tab. App-level PING/PONG detects WebSockets that are accepted but
forward nothing and switches to SSE after 35 s.
- The editor shows the active channel for shared notes.
- Tests: engine channel tests (push, heartbeat, lease on focus, long
polling, interval fallback, switching), realtime fallback tests with fake
WebSocket/EventSource, Go tests for PONG and DOC_SEQ delivery, and
e2e/channels.e2e.mjs measuring latency behind six simulated proxy setups
(0.2-0.3 s on all live channels, ~3 s with plain polling).

Phase 0 of the collaboration plan:
- Remove BroadcastToAll; task, task list and workspace folder events now
only reach users who can see the resource. Task list events carry only
the list ID, clients reload with their own permissions.
- Reject unauthenticated WebSocket/SSE connections (401). Every room join
(URL room, JOIN_ROOM, SSE rooms) is checked via a room authorizer;
/events/rooms requires login and only accepts the caller's own sseId.
- Reorder rejects tasks the caller cannot access or edit (IDOR).
- Lift the server WriteTimeout for SSE streams so they are not cut after 30s.
- Fix folder share removal sending DOC_DELETED to the share ID.
- Tests for all of the above; docs and flaw list updated.
