Versioned public record
Opportunity Evidence Briefs
Each verified data release keeps its citywide research lead, underlying measurements, source ledger, and interpretation boundary. New evidence adds a version; it does not erase the record that came before it.
The boundary
A lead is not a conclusion
These briefs organize aggregate public evidence for further research. They do not establish causation, identify the same young people across datasets, predict individual outcomes, or automatically determine what the Advocate will publish.

Every signal version remains inspectable
