DOCUMENTATION
How ExactClose produces an explainable QC record
The system separates evidence extraction, deterministic computation, reviewer judgment, and immutable reporting so each layer can be tested and audited independently.
System boundary
ExactClose is workflow and analysis software. It does not make credit decisions, independently verify third-party facts, provide legal advice, or become the lender's QC plan. The lender controls scope, sampling parameters, severity, escalation, and final dispositions.
Ingestion
MISMO/ULAD, UCD, and ULDD XML is parsed directly with entity expansion disabled. PDFs use configured vision providers only for transcription into a strict field allowlist. Embedded document instructions are untrusted. Structured extraction stores SSN/TIN last-four only.
Deterministic review
- Regulation Z timing and tolerance
- Reproducible random/statistical sampling
- Configurable document completeness by product and channel
- Cross-document data reconciliation
- Reverification status and evidence workflow
Finding lifecycle
Automated findings begin open. An authorized reviewer confirms, remediates, clears with evidence, or accepts risk with a rationale. A loan cannot be completed while critical or major findings remain open.
Reports and provenance
Each PDF snapshot includes the engine version, loan facts, findings, dispositions, inventory hashes, reverification status, and primary rule references. The encrypted file receives its own SHA-256 integrity digest.
