The fuzz harness swallowed the target's exit status through '|| true', so
a SIGSEGV counted as a pass; the status now propagates (a planted crash
yields 139) and payloads derive from a logged, replayable seed, with a
missing python3 failing the gate instead of generating zero mutations.
The Windows guard runner classified unknown exit codes as skips; the
contract is now explicit (0 green, 1 red, 2 precondition-skip, anything
else a failure) and an all-skip run fails as verifying nothing.
The smoke suite gains crash-class detection on the phase-9b tolerance
paths and phase 11 kill handling (rc >= 128 or a missing jsonrpc banner
fails), a free-port pick plus readiness poll for the UI phase, and a
phase-15b failure that actually exits nonzero.
The soak reader resynchronizes on late JSON-RPC responses by draining to
the matching id, and the analysis fails when fewer than 60 percent of
snapshot attempts produced rows — a vacuous analysis previously passed.
