A sensor or chemometric model cannot support a broader classification, age, authenticity, or quality claim than its product-specific calibration and validation set can justify.
A strong, representative multi-product calibration can generalize within a defined domain. The boundary must be demonstrated rather than assumed.

Promoted to Established after SRC-111 added explicit calibration, independent-validation, prediction-error, and outlier requirements plus separate rye-, barley-mash, and molasses models at a working distillery.
Atomic idea
A sensor or chemometric model cannot support a broader classification, age, authenticity, or quality claim than its product-specific calibration and validation set can justify.
Reasoning
Sample state, instrument setup, preprocessing, composition, operator procedure, uncertainty, and reference-set coverage all affect model output. A fast signal is evidence only within the domain that was actually tested.
Counterpoints
A strong, representative multi-product calibration can generalize within a defined domain. The boundary must be demonstrated rather than assumed.
Fresh source review
Fresh chapters8 and13 support bounded model interpretation; repeated calibrations are not independent sample replication, and age-model error is not universal authentication performance.
