Harvest integrity
Passed
Confirms current-data acquisition, provenance and quality-stage mechanics only.
Current publication gates
Scientific episode release
Blocked
18 screening event(s); required missing dimensions: competing source assessment, official meteorology, regional model context.
Harvest integrity passed; scientific episode release remains blocked pending required corroboration.
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.
Current observatory position
Evidence platform active; scientific release constrained
AQ26 is now API-led. Official measurements are harvested before the Google Drive evidence archive is inventoried. Every displayed number is generated from the latest validated workflow output and is withheld when its source stage is insufficient.

Mandatory stream limitations
- met_office_land_observations: observed Credential Present; required Records Downloaded.
- cams: observed Credential Present; required Metadata Only.
A listed limitation means the relevant stream has not yet reached the required validation stage. It is shown openly rather than replaced with stale data or a false success state.
Current particulate intelligence
Screening candidates identify unusual observations for review. They do not identify a pollution source and are not facility rankings.

Episode bundles report observed facts, contrary/competing context and missing gates. They do not name a source.
Evidence and archive integrity
Google Drive is used as an evidence archive, provenance inventory and backup. It is not the primary source of environmental measurements.
Scientific boundary
This status describes acquisition, validation and evidence-integration readiness. It is not source attribution, a permit-compliance finding, an exposure estimate, a health-risk assessment or a legal determination.
