  "description": "Reconciles an AML consent-order remediation lookback's order-scope population against the extract actually produced for re-screening, per historical period. Coverage is always measured against the caller-declared SOURCE-SYSTEM record count, never the extract's own self-reported count -- a lookback that reports zero gaps because it only counted what the extract already contains is indistinguishable from a clean lookback, and catching that blind spot is this node's purpose. A second axis reconciles versioned policy-list snapshot availability: any period whose sanctions/PEP list snapshot was not preserved is flagged unverifiable and excluded from the screened-coverage total rather than silently re-screened against today's list. Also flags duplicate records surviving dedup. Deterministic reconciliation arithmetic only. Zero network, zero PII.",
