All 28 die to the suite as it stands. The seven tests #76 proposes were written and probed against the same 28: between them they kill 23, none of which the suite misses, and they miss the four no-allocation mutants and HASH_NIL. No test added. main has since moved to 092293e by a README-only commit and a NatSpec-only commit: test/ is byte-identical to the scanned commit and src/ differs from it only in /// lines, so every mutated line is unchanged."
