Methodology
We treat Polymarket as the market-implied prior, then update with official KBO schedule, team hitting, team pitching, expected runs, home field, and public news. Each event keeps the same finance-article structure: explicit market disagreement, causal chain, key factors, Bayesian adjustment, alternative explanation, and a wrong-case test. The result is stored for post-game calibration.
Conclusion
The highest-information checks before first pitch are lineup confirmation, starting-pitcher confirmation, bullpen availability, and whether any injury item changes the expected-run baseline. The article should be judged after settlement by whether the hypothesis identified the right side of the market disagreement, not by whether every low-confidence pick won.
