* Let ngtcp2's handshake through a path that reorderseunhhu2026-09-291-1/+8
| | | | | | | | OpenSSL 3.5's ClientHello offers ML-KEM with X25519 and takes two Initials; when the path brought the second first, ngtcp2's server was asked for a Retry and the harness gave up. The client now offers X25519 alone, as Pure's links agree, and the server lets go of a connection it may not keep, so the client's next Initial begins another.
* Put ngtcp2 beside quinn in M6, as it is in M5eunhhu2026-09-291-45/+170
| | | | | | | | | drain.c takes a rate and seconds as quinn's client does (paced messages stamped with the time they were written, and no more written past the seconds), and its service writes quinn's line for each stream: the messages read in each 100 ms and how long they took. 020's run.py runs it as a third, on port 40005 behind the same bottleneck, and --who picks whom to run.
* Put ngtcp2 beside quinn in M5, as the design plannedeunhhu2026-09-292-0/+470
ngtcp2 1.25.0 with OpenSSL 3.5's QUIC TLS (its ossl backend), fetched and built into build/third by ngtcp2/build.sh; drain.c does in C what the quinn harness does: one connection, one stream, "pure" and then the messages each after its u32 length, counted by the service, packets in GSO bursts. Its stream bytes are a function of their offset, so what ngtcp2 keeps to send again points into a pattern that never changes. run.py's drain_ngtcp2 measures both sides' CPU as drain_quic does. Five rounds each, both sides' CPU a message: 61 B Pure 0.280, ngtcp2 0.270, quinn 0.310 us; 1 KiB 2.62, 3.54, 3.94; 16 KiB 40.2, 54.4, 60.2.
