Evidence

Fingerprint

Represent a deterministic fingerprint used to reference content or data without requiring PAR to custody the source file.

Purpose

One function. Explicit trust boundaries.

Evidence is represented as verifiable technical and provenance material, not merely as uploaded content.

Every material state transition should remain attributable to an authenticated actor, an authority context, a timestamp and the evidence required to reconstruct what happened.

Operational flow

Fingerprint lifecycle.

Acquire source reference

Canonicalize / fingerprint

Timestamp evidence

Bind provenance

Preserve verification metadata

Object model

Minimum verification context.

The exact schema can vary by object class and policy version, but the verification layer should be able to resolve these core dimensions.

Status modelDefined

Production status must always be sourced from the deployed service and published through System Status; this static package does not claim backend activation.
