Evidence class composition

Counts are evidence-inventory categories, not claim weights.

Location evidence status

No location-specific context was activated in this release.

The observatory has no standing location register. Locations appear only after a monitoring event fixes the time window and geography and official inventories supply relevant context. Empty zero-value cards are intentionally suppressed.

How to read this page

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.
