The Calibration Ledger

Anyone can write a confident memo. The harder thing is to date the call, attach a probability, and let reality grade it. Every prediction below carries a conviction level and a resolution date.

Hit rate counts resolved calls (a partial counts as a half). The Brier score measures calibration — the squared distance between the stated probability and the outcome, where lower is better and a coin-flip scores 0.25. At 0.134 across the book, the calls are meaningfully better-calibrated than chance.
