Public-health interpretation boundary
SCC Air Quality keeps emissions, ambient concentrations, exposure and health outcomes separate. health-based reference-value contexts are used only as health-context prompts; they do not identify the source of pollution.

Manual review requiredBenchmark cards are public-health context only. They are not source-attribution findings.
Source-attribution caution
The automated site must not collapse these evidence classes into a single causal claim.
UKHSA-style balance
The public output is framed to support evidence review and challenge. It does not override regulator, public-health or permit determinations, and it does not assert that a modern regulated facility is or is not a significant public-health risk.
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.
