Critical: broker HTTP auth via cli_session bearer token on all /cli/*;
file download requires auth+membership; v2 claim gated; duplicate
claimInviteV2Core removed; grant enforcement tries member then
session pubkey; audit hash uses canonical sorted-keys JSON.

High: rate limit args fixed (burst 10, 60/min) + both buckets swept;
BROKER_ENCRYPTION_KEY fail-fast in prod; migrate uses pg_try + lock_
timeout; hello validates sessionPubkey hex; blocked DMs rejected pre-
queue; watch timers cleaned on disconnect.

Medium: inbound pushes serialized; reconnect jitter + timer guard;
hardcoded URLs through env; v2 claim path configurable.

Low: WSHelloMessage optional protocolVersion+capabilities.
