April 2025 performance summary: Delivered two high-impact changes across mozilla/bigquery-etl and mozilla/bedrock, delivering measurable business value through improved data quality, cross-channel reporting, and enhanced user assistance. In mozilla/bigquery-etl, the Unified Broken Site Report now aggregates multi-channel data (Fenix, Fennec, Firefox beta/live) into a single live view with standardized app_name and deterministic row ordering. In mozilla/bedrock, added a discoverable Matrix support file (.well-known/matrix/support) with administrator/security contacts and a dedicated support page URL to improve user assistance and incident response. These changes improve data completeness, reporting reliability, and readiness for incident response.
