When a proxy lets neither WebSocket nor SSE through, the app opens a
poll connection: the server buffers its events (an SSEClient without a
stream), each GET waits up to 25 s, and room joins work like for SSE.
Tasks and lists now update live there too, and note sync takes its
notifications from it instead of a second long poll. Idle connections
close after two minutes. The profile shows such a connection as limited.

- Every login is a session (device, IP, last use); the token's jti is its ID.
Sessions end on logout, per device from the profile, or after 30 idle days.
- Tokens older than a day are renewed via the X-Session-Token header.
- Changing password or login e-mail needs the current password; a new
password logs out all other devices and mails the old address.
- Demo reset keeps the demo visitors' sessions.
- revoked_tokens is replaced by sessions (migration 4); everyone is logged
out once after the upgrade.

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.
