Three facts the client cannot produce alone, kept deliberately separate: mtu.pmtud_down (largest datagram that arrives unfragmented — meaningful only because the server sets DF), mtu.frag_delivery (whether larger ones arrive once fragmentation is allowed), and train.udp_downstream (loss, reordering and arrival spacing in the download direction, which a round trip cannot separate from upstream loss). ServerMeasurement now runs them on the same ProbeSession as the echo train. It had to: a fresh session restarts client-side sequence numbers and the server's anti-replay window discards the lot, so the re-primed source is never recorded and every granted send goes to a socket that has already closed. That produced four confidently-wrong FAILED tests and a RED verdict on a healthy network. Live against fmr: path MTU 1500, fragments to 4000, 100/100 downstream, GREEN.
