Confirmed = pulled plans on this letting (revealed interest, from the agency portal). Likely = firms that bid SC signals work in the last 5 years, ranked by frequency. Win rate is historical — the share of bids that firm entered and won, not a prediction of this letting.
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 →
