BloodKetones identifier does not match HealthKit; BloodKetone cannot be queried

[sfourdrinier]

Summary

Verified against Apple's current HealthKit SDK (Xcode iOS 26.5 HKTypeIdentifiers.h) and against @kingstinct/react-native-healthkit 14.1.0 on device (iOS 26.6.1).

Blood ketones: this package advertises a type Apple does not ship

Apple's current HKTypeIdentifiers.h declares HKQuantityTypeIdentifierBloodGlucose, HKQuantityTypeIdentifierBloodAlcoholContent, and the blood-pressure quantity types. It does not declare HKQuantityTypeIdentifierBloodKetone or HKQuantityTypeIdentifierBloodKetones.

This package's generated schema and Nitro enums still include HKQuantityTypeIdentifierBloodKetones.

On device, queryQuantitySamples("HKQuantityTypeIdentifierBloodKetones") fails with:

Failed to initialize unrecognized quantityType with identifier HKQuantityTypeIdentifier(_rawValue: HKQuantityTypeIdentifierBloodKetones)

That matches HKQuantityType.quantityType(forIdentifier:) returning nil for a string that is not an Apple identifier.

Passing Apple's historical singular spelling HKQuantityTypeIdentifierBloodKetone fails earlier in Nitro:

Cannot convert "HKQuantityTypeIdentifierBloodKetone" to enum QuantityTypeIdentifier - invalid value!

Please drop HKQuantityTypeIdentifierBloodKetones from the public identifier union, or only expose identifiers that exist in the current HealthKit SDK headers.

Environmental audio exposure event: this identifier is real

The same SDK header still declares:

HKCategoryTypeIdentifierEnvironmentalAudioExposureEvent API_AVAILABLE(ios(14.0), watchos(7.0), ...)

Apple's docs: https://developer.apple.com/documentation/healthkit/hkcategorytypeidentifier/environmentalaudioexposureevent

On the same device, queryCategorySamples for that identifier failed with unrecognized categoryType (categoryType(forIdentifier:) nil). That looks like a Kingstinct initialization bug, not a missing Apple type. Apple Watch noise notifications write this type; it is read-only.

Please check initializeCategoryType for HKCategoryTypeIdentifierEnvironmentalAudioExposureEvent on current iOS.
