How to read this. Plan‑pull counts come straight from agency portals. Patterns and confidence scores are derived from comparable lettings (same county, same category, three‑year basis). Confidence is a calibration of past correctness on signals of this shape — not a guarantee of this bid’s outcome. We never round up. More on what Cassandri does →
