Evidence-readiness gates and public-claim limits for This Air Quality Project reporting.
Passed
Confirms current-data acquisition, provenance and quality-stage mechanics only.
Coverage Gap
108 of 129 governed PM sites represented through SOS; 83.7% against a 85.0% live-source threshold.
This governs the live/current SOS route only; it is not the England 30-day AURN review completeness metric.
Operational screen complete
Adjusted PM2.5 candidate count: 0; eligible station assessments: 125; not eligible or not assessed: 3; required missing dimensions: none reported.
Acquisition status distinguishes primary monitoring evidence from mandatory contextual sources. A degraded context harvest may support a clearly labelled data-availability release, but not an environmental episode, source, compliance, exposure or health finding. No England-wide current environmental assessment is published because the governed monitoring coverage and freshness gate was not met. No episode was available for corroboration. Cross-source convergence was not applicable to an episode in this run.
A green harvest gate is not a pollution-source finding. Source attribution, causation, permit breach, exposure and health conclusions remain prohibited unless the separate scientific gate passes.
1 mandatory stream gate(s) remain constrained. The public site reports verified acquisition and readiness without converting incomplete data into scientific claims.

A gate marked partial, context-only, needs-review, missing or not-ready must not be used as proof. It is a prompt for follow-up review and expert challenge.
Measurements, station and regional coverage, descriptive calculations, source records and stated limitations are the evidence available for review.
Automated checks confirm that the pipeline followed its declared rules. They do not constitute peer review, accreditation, regulatory approval or institutional endorsement.
Adjusted PM2.5 candidate count: 0; eligible station assessments: 125; not eligible or not assessed: 3. A count of zero means only that no eligible assessment crossed every current operational criterion. It does not establish absence of pollution, harmless concentrations, assessment of every station or screening of all pollutants.
Formal false-discovery-rate control has not been established. The live screen does not identify a source and is not a health assessment or regulatory determination.
