A statistical estimate from our own model of past outcomes — an insight, not a guarantee. Policymaking is volatile.

Not enough signal yet to read this bill's trajectory — we surface a likelihood only once there's real movement (stage, sponsorship, committee, or votes) to point to.

Based on stage, sponsorship breadth, committee status, recorded votes, and cross-state momentum — a description of the observable signals, not a prediction.
