longrtt failed against aioquic with "Expected at least 2 ClientHellos. Got: 1" because our client started sending Initials before the sim's ns3 + tcpdump capture finished initializing. Only the PTO retransmit hit the wire — the original ClientHello was sent during the sim's ~1s readiness window and never captured. aioquic, picoquic, and quic-go all gate their client launch on /wait-for-it.sh sim:57832. We didn't. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
