Verification paths
One question — four honest outcomes
The schema and period differ between snapshots, so the automatic diff is not interpreted.
Sources
Source PassportA versioned source record describing ownership, legal basis, coverage, freshness, risk and collection-admission state. and version
Source admission is separate from found material; this source exists only as a test fixture.
Synthetic fixtureA deterministic record created for repeatable testing that represents no real person or event.source:public-data-change
Synthetic versioned register
- Owner
owner:reference-methodology- Access method
- fixture
- License
- CC0-1.0-synthetic
- Risk tierA category determining the required authorization, isolation, review and human oversight for a source or operation.

Coverage
Two immutable snapshots, bounded pagination and a deterministic diff.
Rights basis
Synthetic public fixture; no real person, organisation or event.
Source versionA source state fixed at a point in time with a digest, locator and change description.source-version:public-data-change-001
