How a record is made — and what it cannot prove.
How STREETS verifies condition records and handles recurrence, scoring, provenance, uncertainty, and public reporting.
Documentation
A condition is photographed at a location on a date and described in plain terms. Locations are generalized to block face when an exact address is not operationally necessary.
Human review
A person checks that the condition is visible, the location is accurate, identifying details are absent, and any recurrence judgment is defensible. Records that fail review are held.
Recurrence versus duplicate
Two reports about the same pile on the same day are duplicates. A new pile at the same location weeks later is a recurrence. Borderline judgments are documented so another reviewer can disagree and recount.
Provenance
Where public case IDs or source records exist, STREETS retains their provenance and distinguishes source facts from operator interpretation. Missing access is stated as a limitation.
Limits
Photographs can show that a condition existed at a place on a date. They do not prove cause, duration, or responsibility. A blank corridor means nobody documented it; it does not mean the corridor is clean. Scoring rules are versioned, and earlier outputs retain their original version marker.
