Receipt Families

Assay compiles selected external outcomes into portable evidence receipts and bounded Trust Basis claims.

The current public claim-visible families are:

Source surface Receipt family Trust Basis claim
Promptfoo assertion component result eval outcome receipt external_eval_receipt_boundary_visible
OpenFeature boolean EvaluationDetails runtime decision receipt external_decision_receipt_boundary_visible
CycloneDX ML-BOM machine-learning-model component inventory / provenance receipt external_inventory_receipt_boundary_visible

Mastra score events and Pydantic case results are importer-only receipt lanes in this line. They do not expose public Trust Basis claims.

Use the machine-readable receipt family matrix for the source-of-truth family paths, schema names, included fields, excluded fields, non-claims, and importer-only status.

Use the receipt schema registry for the bounded JSON Schema contracts exposed through assay evidence schema.
