Receipt checking reference

The full document validator chooses the receipt family before a family-specific verifier runs. Do not substitute a parsed object for original wire bytes when investigating duplicate fields, escaped discriminators, malformed JSON or canonicalization.

Reference	Owner and role
Protect v2	Seal’s normative whole-receipt contract
Decision receipt schema	Decision-family schema; retain its version-specific and historical distinctions
Document and family parser	Actual intake and discriminator rules
Protect verifier	Commitment, signature and local replay checks
Spine verifier	Older signature/binding checks without replay

For a refusal, retain the exact diagnostic, format, source revision and key provenance. A commitment mismatch suggests altered or inconsistently constructed contents; a signature mismatch can also mean the wrong public key. Neither should be repaired by editing the original receipt until the check passes.

Results explains authority and occurrence limits. Formats records the decimal compatibility gap at these revisions.
