UDP datagram truncation
An AI wrote this C UDP receive loop for a telemetry collector. Large datagrams come through 'corrupted'. Find the bug, the datagram size that triggers it, and the fix.

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it (tests, edge cases, reading critically), and how you’d re-prompt or decompose to get it right.

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
Run or narrate your approach, then ask the coach.
