extensions/robustness-evidence.md: a corpus named item by item by the SHA-256
of its samples, the attack battery as registered integer transforms with
parameters and seeds (synthesis §7.5.7's battery with its parameters free, and
gamma), the signed robustness record whose table the harness recomputes and
whose rates are exact fractions, and the robustness claim that holds only
where every item of a cited record's corpus survived the attack and no
negative was read as marked. wai-rs module robustness (feature robustness),
wai_robustness_vectors, the corpus with wai-mark:tent64's records over the
measurement sets and its claim, and robustness_verify.py, which reruns the
conformance battery end to end with _wai_mark.py.
