    description: >-
      GenAI reporting API over canonical analytics rollups. Accepts a metric
      name, time range, grain, group-by, and filters; returns a typed time
      series and optional totals.
  - name: ReportingService
    description: |-
      ReportingService exposes a single QueryReport RPC that maps allowlisted
       analytics payloads onto safe rollup queries. Callers never send SQL;
       the backend picks the rollup family and grain from the metric
       catalogue, the requested range, and the requested grouping.
