# Outcome matching Canonical HTML: https://spoolis.com/docs/matching. This page is also available in machine-readable Markdown. Match vendor-reported claims to buyer-side facts with deterministic, versioned, explainable rules. ## Rules are data Rules declare fields, windows, tolerances, cardinality, priority, duplicate handling, and ambiguity behavior. Every result retains rule and fact references plus an explanation. ## Uncertainty stays visible Mismatches and duplicates create discrepancies. Ambiguity remains uncertain. AI-assisted suggestions are disabled by default, cite known facts, run only after deterministic uncertainty, and never produce matched. ## Fact authority Resolution policies declare source precedence, corroboration, freshness, and disagreement behavior. Adapters never hide conflicts.
