Proof

rn-apple-healthkit

native-seam only — upstream constants merge and method export run from the bundle; initHealthKit reports HealthKit data is not available, saveSteps/saveMindfulSession default a missing endDate to now, ISO8601 dates parse as yyyy-MM-dd'T'HH:mm:ss.SSSZ, and nil NSError maps to Unknown error from a native module / E(null)0
