- MobileUserSocket: cap new socket connections per IP at 30/min via
Aprsme.RateLimiter. Denials log and return :error at handshake.
Tests bypass the check (no real peer_data).
- MobileChannel: rate-limit the expensive client-initiated handlers
(subscribe_bounds, subscribe_callsign, search_callsign) at
30/minute per socket. Streaming packet delivery is unaffected.
- MobileChannel: historical packet loads now arrive as a batched
`packets` event (100 per frame) instead of one `packet` frame per
row. Live streaming still uses the single `packet` event.
- Updated docs/mobile-api.md with the `packets` event and rate-limit
semantics; migration note preserves compatibility for clients that
only handle live `packet` events.
- Create MobileChannel for geographic bounds-based packet filtering
- Add MobileUserSocket for mobile client connections
- Implement subscribe_bounds, update_bounds, and unsubscribe events
- Leverage existing StreamingPacketsPubSub infrastructure
- Add comprehensive mobile API documentation with Swift examples
- WebSocket endpoint: wss://aprs.me/mobile/websocket
- Channel: mobile:packets
This enables iOS/Android apps to receive real-time APRS packets
filtered by geographic viewport, with efficient bandwidth usage.
