# Variable: weightMeasurementSchema

Defined in: [packages/core/src/domain/schemas/health/weight.ts:12](https://github.com/pablo-albaladejo/kaiord/blob/3eacbe62ef72342d970523967cc5155b5935bb85/packages/core/src/domain/schemas/health/weight.ts#L12)

Zod schema for `extensions.health.weight` — a scalar weight measurement
captured at a point in time. Body-composition fields (fat percent, lean
mass, water, BMI) live in the separate `body_composition` payload so
scales that only report scalar weight produce a valid payload without
partial fields.
