Traceable citation+10 / 10
A direct link to the primary reporting is published with the record.
Location resolved+8 / 8
The event is resolved to coordinates, allowing geospatial cross-checking.
Analyst verification (L6)0 / 12
Awaiting analyst desk verification; the record stands as collected.
Integrity deductions-10
Confidence reduced because the originating feed declares the report unconfirmed.
