 checks and bounded smoke tests; it is not an acceptable full-training path when Metal is
 available.
 The completed Metal run stopped after epoch two and selected epoch one at 94.42%
 fake-quant validation accuracy and a 95.59% teacher-aware selection score. Its selected
 float checkpoint improves frozen v1 to **95.09% (891/937)**, two correct decisions above
 the accepted baseline's float checkpoint. That gain does not survive export: the matched
 23,148,500-byte int8-QDQ graph scores **94.66% (887/937)**, 94.66% macro recall, and
 94.17% scored-hard accuracy. It is five correct decisions behind the accepted int8
 baseline and fails the 95% shipping gate. Preserve the artifact as a rejected experiment;
 `purpose-lite-v1-distilled-qat-mlx-4e` remains the candidate of record.

 Core ML Tools no longer maintains the legacy ONNX converter, so the Apple artifact is
