/**
 * src/gates/output-contracts.ts — output contract data + validation gates,
 * ported verbatim from the ZOB harness delegation output contracts.
 *
 * Contract data and validation logic are PURE. `readReferencedArtifacts`
 * performs fs reads (STATEFUL) but only when a `repoRoot` is supplied, keeping
 * the pure validation path fs-free and testable. `applyChildGates` mutates the
 * ChildResult in place, matching the harness exactly. Zero @earendil-works/*.
