Covers gost#911 at the wire level: four UDP source sockets send through one RUDP reverse tunnel bound on a relay server, and every datagram must come back byte-identical to its own endpoint. A frame torn by an interleaved writer shows up twice — as a corrupted payload, and as the torn frame leaving half a header in the stream, which the far end reads as "unexpected EOF" and answers by rebuilding the whole tunnel. So the suite asserts both: no endpoint sees a corrupted datagram, and no endpoint sees a receive gap long enough to be a teardown and rebind. Verified against a binary built before the fix (4 endpoints, 35% loss, 1.4s gaps, suite fails) and after it (0% loss, no corruption, 0.2s gaps, passes).

# The rudp listener opens no local port — it binds the UDP port remotely through
