Waiting for the first score

As soon as you move a rail, this panel shows the survival odds, the single largest risk factor and the date the projection turns.

Every score on this page comes from model pact-survival@2026.10.0, fitted on 8,040 placements across 24 cities with real weather, and running entirely inside the serverless function. There is no external model API in this request path.
