Evidence
Timestamp
Record verifiable time evidence and renewal/migration metadata where applicable.
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
Timestamp lifecycle.
01
Acquire source reference

05
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.
- Evidence ID
- Fingerprint / digest
- Algorithm profile
- Timestamp
- Source
- Provenance
- Chain links
- Status

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.
