pub fn defeater_fingerprint(q: &NQuin) -> u64Expand description
Produces the defeater-matching fingerprint for any Quin (norm or defeater).
Two Quins share a fingerprint iff they bind the same party (subject),
the same contract graph (context), and the same property-path
(predicate[8..62] — the portion above the opcode byte and below the
defeater bit). The opcode byte and defeater bit are masked out so that a
q42:unless node correctly matches the norm it defeats.
