# description
Input to a size recommendation. The REST API wraps this as {"chart": "<slug>", "input": <this document>}. Open Sizing Schema v0.1: versioned, subject to change until 1.0.

# $defs.RecommendInput.properties.height.description
demographic inputs used ONLY for anthropometric estimation, never for matching directly

# $defs.BodyMeasurement.properties.value.description
central value in integer mm (length) or g (mass)

# $defs.BodyMeasurement.properties.variance.description
symmetric spread in same unit; 0 for self-reported tape measurements

# $defs.BodyMeasurement.description
A body measurement as a distribution, not a point (Blueprint §4 Stage 2).

# $defs.MeasurementSlug.description
Mirrors measurement_definitions.slug in the schema. Body and garment measurements are distinct identifiers by design, never a flag.
