Evidence
We publish the method before the result.
Every claim on this site that carries a number is backed by a study you can inspect. Each one is pre-registered and hash-locked before any evaluation data is opened, and reported with its denominator, its confidence interval, and its failures.
Published studies
Method
Pre-registration
Thresholds, metrics, denominators, and rule logic are frozen and hashed before any evaluation data is retrieved. The lock file refuses execution if anything changed.
Held-out separation
Calibration, validation, and held-out sets are split by organisation, not by sampling. The held-out set is opened exactly once.
Reported failures
Aborted cases, unmet targets, and under-powered axes are published with their reason codes. A study that misses its planned sample size says so.
