Excludes Kaggle datasets, US DoL H1B records, newsletter snippets, and manual drops — sources that arrive thin by design and have no canonical URL to fetch from. The composite quality score (D3) is computed against this surface so the rating reflects actual pipeline operations, not data origin.

Methodology: scripts/data-quality-snapshot.py runs daily, queries volume + coverage + freshness across jobs, intel_jobs, intel_papers, intel_news_events and intel_salary_benchmarks, then writes the result into the data_quality_snapshot table with snapshot_date + snapshot_version as the unique key. The composite score is a weighted average of D1-D6 (D3 quality 25%, D4 substrate 25%, D5 UI 20%, D1 architecture 15%, D2 engineering 10%, D6 security 5%). Source code is committed to the repository.
