API-led source coverage
This Air Quality Project considered 54 registered streams and observed 54 in this run. Each stream is labelled by its real validation stage rather than by whether a credential merely exists.
Source register summary
The canonical register tracks 54 current and planned sources through credential, connectivity, metadata, download, schema, quality and production stages. The unproven legacy Drive archive is disabled and has no scientific influence.

Scientific evidence and software assurance are different
Scientific evidence
Measurements, station and regional coverage, descriptive calculations, source records and stated limitations are the evidence available for review.
Engineering assurance
Automated checks confirm that the pipeline followed its declared rules. They do not constitute peer review, accreditation, regulatory approval or institutional endorsement.
