Major additions to the NIP specification:
- Gift wrap expiration: documented that outer gift wraps MUST
include expiration tags so relays can garbage-collect signaling
- Event structures: added full JSON examples with all required
fields (pubkey, id, sig, expiration, alt tags)
- ICE candidate buffering: documented that candidates MUST be
buffered while ringing and NOT cleared on accept
- Staleness and deduplication: documented 20s staleness check
and event ID dedup as spam prevention requirements
- NAT traversal: added TURN server guidance for same-WiFi and
restrictive network fallback (~20% of cases)
- Audio routing: documented MODE_IN_COMMUNICATION, earpiece/
speaker/Bluetooth SCO cycling, ringback tone, ringtone
- Platform integration: foreground service (microphone type),
proximity wake lock, PiP mode, runtime permissions
- Error handling: SDP creation failures, ICE_CONNECTION_FAILED,
session creation errors
- JSON escaping: noted that ICE candidate SDP strings MUST be
properly escaped in the content JSON
