Project method and boundary

Data quality

Publication is fail-closed when required real data, source attribution, legal status, privacy safety, or source schema cannot be established.

Automated gates

Required sources must be present and non-empty, snapshots fresh, record-count changes within reviewed bounds, identifiers deterministic, regulatory statuses explicit, and public fields privacy-safe.

Limits of validation

A passing report validates the pipeline contract and published representation. It does not establish that an official source is complete or that an underlying event occurred as reported.
