Validate Kokoro Core ML
- Freeze the source revision, export configuration, package hashes, fixtures, dtypes, shapes, and threshold before observing results.
- Run
kokoro/coreml_numeric_validate.pyandkokoro/coreml_export_verify.pyor the narrow equivalent for the changed export. - Test the actual package on the target device when the claim concerns scheduling or deployment; separate numerical parity from audio/listening quality and performance.
- Run
scripts/validate_sdk_bundle.mjsfor hosted SDK bundle changes. - Fail closed on shape, dtype, output, fallback, package-identity, or fixture mismatches. Never loosen a preregistered threshold after seeing a result.
