the WORST letter — a contract is as strong as its weakest graded dimension (the safe value to GATE on).

@suluk/harden— schema hardening as a derived, scored contract facet. Audit a v4 'Suluk' document's INPUT schemas for the validations that keep malformed/oversized input from breaking the system, grade them A–F, surface the grade to incentivise the author, and gate CI on a minimum.import { auditDocument, assertGrade } from "@suluk/harden"; const report = auditDocument(doc); // { grade, score, byOperation, findings, bySeverity } assertGrade(doc, "B"); // throws if the contract is too weak (the hard incentive)
