调研方向
Start with the TCP and UDP server entry points at modules/network/src/server/tcp.server.network.ts and modules/network/src/server/udp.server.network.ts, then trace the packet and candidate queues in peer-host.ts and packet.ts. Read how the existing signaling server sets maxPayloadLength and check for network tests covering frames and queue behavior. Done means frame size and per-peer queues, including pendingCandidates, are bounded, with tests demonstrating the limits.

Issue description
The TCP and UDP Bun.serve calls keep Bun's default maxPayloadLength (about 16 MB); only SignalingServer sets one (signaling.server.network.ts:77). Per-client packet queues and pendingCandidates have no cap on count or bytes, and there is no rate limit. Each frame is copied twice and every typed packet is JSON.parsed even when nothing listens. One connected peer can exhaust server memory and CPU.
Where:
modules/network/src/server/tcp.server.network.ts:98modules/network/src/server/tcp.server.network.ts:134modules/network/src/server/udp.server.network.ts:174modules/network/src/server/peer-host.ts:315modules/network/src/shared/packet.ts:238
Evidence:
client.packets.get(frame.channel)?.push(frame.data);
webSocket.data.pendingCandidates.push(data.candidate);
if (payload) state.packets.push(payload);
grep -rn maxPayloadLength modules/network/src → only signaling.server.network.ts:77.
Suggested fix: Set maxPayloadLength (e.g. 64 KiB) on TCP and UDP, and cap per-peer queue length or bytes (drop the oldest or close the peer) and pendingCandidates.
Found during a code audit of main at be72076.
