# Sources and provenance

The build used snapshot `hmlr-public-metadata-v0.2.0`, observed
`2026-07-29T18:00:00Z`. Network acquisition is separate from this offline
build. Every record retains a canonical URL, source family, authority tier,
observation time and source URLs. Normalisation does not transfer authority.
