The `receipt_registry` field added after issue is not part of the hashed receipt.","matching_rule":"A row is on a receipt only if the source printed the exact official key supplied (UEI, NPI, EIN, CIK, CCN, registry number) or the exact printed name after whitespace collapse and case folding. No fuzzy, phonetic, partial or owner/affiliate matching.","absence_rule":"A source that was not read is listed in did_not_answer and its check carries state 'did_not_answer' and count null. 'No record' may only be stated for a source that answered.","verdict_rule":"A conforming receipt contains no score, rating, risk label, clearance, compliance badge, signal, anomaly or fraud statement. Sources' own published ratings may be printed if attributed to the source.","linkage_rule":"Every crosswalk edge cites the one official row that prints both identifiers together. Edges are never derived from name similarity, shared address, ownership or co-occurrence.","provenance_rule":"Every file-based check names the file, its SHA-256, its row count and read time; every API-based check names the endpoint's publisher and the read time; rescued or third-party-hosted copies state the custody chain and the originating publisher's current record.","conformance_levels":{"A":"schema valid + hash matches + absence rule + verdict rule","B":"A + linkage rule on every edge + provenance on every file check"}}
