/**
 * RMSSD HRV from HealthKit (#1110), against real Postgres: iOS / watchOS 27
 * added `HKQuantityTypeIdentifierHeartRateVariabilityRMSSD`. Both ingest
 * paths, the live batch and the `export.zip` import, read the one mapping;
 * each must store it as `HRV_RMSSD`, apart from SDNN, and keep a reading
 * above the old 200 ms ceiling instead of skipping it for good.
