  "description": "Runs a caller-declared, versioned journal-entry testing ruleset over a caller-declared JE extract and flags each entry that trips one or more rules: weekend/holiday postings, round-number entries, suspense/manual-account postings, post-close entries, and unusual user/account pairings. Every firm-specific convention (which rules are active, what counts as a round number, the weekend day set, the holiday calendar, the suspense-account list, the period-close date, the authorized user/account pairing list) is a caller-declared policy input, never a silent default; the ruleset_version string is echoed verbatim in the output so the artifact records exactly which policy vintage produced the flags. Optionally binds to a caller-declared extract_population_hash for audit-trail linkage to a hashed JE population (soft coupling only, e.g. to an art-460-style extract-integrity record if that node has landed). First of three ARCB-K-1 substantive audit-recalculation kernels. NaN-safe. Zero network, zero PII.",
