The existing conformance suite compared the two driver styles on open
negotiation with HMAC and DSCP, no-test completion, and peer close. It said
nothing about failed-open rollback, multi-probe scheduling, or the errors
each driver promises for out-of-state operations.
Three tests close those gaps against externally observable behavior only:
a first open that times out against a deliberately mute peer, followed by a
retry that opens, probes, and closes with a fresh sequence; three
caller-paced probes against a real irtt-server, matched sequence for
sequence in both drivers; and equivalent errors for probing before open,
opening twice, and probing or closing after close.
No production code changed, and no divergence between the drivers was
found.
