December 2025 monthly summary for mozilla/docker-etl: Delivered a major overhaul of the rescore workflow with auditability improvements for the docker-etl pipeline, along with CLI usability enhancements. Implemented TOML-based rescore data, templates for updated scored_site_reports, and archiving of previous versions to enable traceability. Added automated schema templates for site_rank updates with a lifecycle log point before deployment. Shifted site-rank-update to template-driven rescoring rather than direct production changes, and introduced a pre-deploy delta recording to capture rescore effects prior to schema deployment. Completed CLI refinements to streamline arguments, remove legacy handling, and standardize dataset defaults. Business value: safer, auditable deployments, clearer change rails, and faster iteration on rescore changes.

November 2025 monthly summary for mozilla/docker-etl: Delivered major enhancements across the ETL pipeline and data platform, including a centralized Context object and a global --stage argument for environment-aware execution, and a template-driven schema loading/updating mechanism with the updated update_schema workflow. Reorganized data and code structure by moving SQL schemas to data/, extracting tree hashing, and refactoring IDs to bqhelpers, enabling robust, template-based schema evolution. Baked in data population for core datasets (metadata, webcompat_knowledge_base, web_features) and added new views (webcompat_risks) and interop_proposals impact data. Improved BigQuery tooling with insert_query/delete_query helpers, mocks, and a schema templates render/validation commands, backed by a new Command framework. Migrated a broad set of jobs to the new infrastructure, and enforced per-job write isolation to prevent cross-job data contamination. All changes collectively reduce operational risk, accelerate metric iterations, and improve data quality and observability.

October 2025 performance summary: Delivered substantial business value across docker-etl and wpt-sync through feature delivery, reliability improvements, and automation.

In September 2025, the team delivered automation, data quality, and measurement improvements across four repositories, strengthening bug triage, build reliability, and data pipelines. Key outcomes include automation of See Also links for web feature bugs with a new Python module and daily cron execution; expanded bug triage tooling (webcompat:japan tag and user-impact scoring for core blockers); modernization of build and dependency management to pyproject.toml, reducing maintenance overhead; robust metric engineering with Japan_1000_mobile and centralized registry, plus backfill capabilities; and enhanced data import pipelines and interoperability to improve cross-repo visibility and correctness. Additional improvements include refined bug import filters (platform-feature) and ensuring interop data flows to webcompat_kb, plus a fix to reintroduce interop import to stabilize the webcompat job. The result is higher velocity, fewer manual triage steps, more accurate prioritization, and a more maintainable tech stack.

August 2025: mozilla/bugbot delivered automated platform bug triage via the Bug Triage Automation: Platform Bug Labeling feature. The feature queries BigQuery signals (breakage reports and prioritized KB entries) to identify site reports likely to be platform bugs and automatically labels them with the webcompat:platform-bug keyword, accelerating triage and prioritization. A single commit implemented the labeling logic, setting webcompat:platform-bug on site reports likely to be platform bugs (#2674). This work improves platform issue responsiveness and reduces manual triage effort, laying groundwork for broader automation across bug triage.
