Proof Evidence Model

Status: draft
Version: 0.1.0

Purpose

Define the canonical control-repo language for Meridian Proof evidence metadata, aggregate links, and export-ready evidence bundle composition over replayable Meridian state.

Proof model

• evidence records store governed metadata for one institutional artifact without storing the raw blob in this runtime
• evidence links attach one evidence record to one replayable aggregate
• evidence bundles group evidence ids for one workflow such as onboarding, settlement, distribution, audit, or dispute review
• replayable Proof state reconstructs from evidence.recorded, evidence.linked, and evidence-bundle.created events

Core records

• evidence
• evidence link
• evidence bundle
• bundle member
• bundle readiness state

Required evidence references

• evidence id
• evidence type
• hash
• storage URI
• controller id
• disclosure policy
• aggregate id
• bundle id
• bundle type

Current runtime boundary

• Meridian Proof currently stores governed metadata, links, and bundle composition only
• raw document blobs, secret storage, and encrypted disclosure flows remain outside this reference runtime
