Broker (all need redeploy):
- sweepOrphanMessages: DELETE undelivered message_queue rows older
than 7 days; hourly sweep. Stops unbounded growth when a sender
typos a name (queued forever, never claimed).
- Per-member send rate limit: TokenBucket(60/min, burst 10) keyed on
memberId so reconnecting can't bypass. Surfaces as queued=false,
error='rate_limit: ...'.
- Pre-flight size cap: reject at handleSend if nonce+ciphertext+
targetSpec exceeds env.MAX_MESSAGE_BYTES with a clear error
instead of silent WSS frame-level kill.
- No-recipient reject: for direct sends, check any matching peer
is connected BEFORE queueing. Kills the self-send silent drop
(sending to your own pubkey when you only have one session
connected) and typo-to-offline-peer silent drops.
- WSAckMessage.error field added for structured failure reasons.
CLI:
- ws-client ack handler reads msg.queued and msg.error; surfaces
rate_limit / too_large / no_recipient to callers instead of
returning ok:true with a dummy messageId.
