The method adds GA4 site/property mapping, minimum read access, a data contract, a daily report template and an offline snapshot checker. Zeroes, empty results, failures, partial coverage, delays and stale data remain separate.
A report generated today does not prove the underlying data refreshed today. Retain the data date, original collection time and quality limits, and verify manual comparison, manual execution, scheduled triggers, artifacts and delivery separately.
The public Skill contains general methods and synthetic examples. Authorized public aggregate dashboards need a separately reviewed field allowlist. The checker does not collect data, create credentials or add recurring tasks.
