Overview

This catalog page exposes the physical schema, coverage, and latest source rows without inventing a normalized grain for publisher-shaped snapshot fields. Use the documented key and event time when comparing revisions or vintages.

Query contract

Preserve one canonical row per (event_time, location_id) before aggregating.

Analysis rules

Group only after preserving the declared grain: event_time, location_id.
