quantized duplicated precisions.json, which is authoritative for the
quantized/non-quantized partition. default expressed a per-repository
recommendation nothing consumed: the library resolves its own per-platform
default. Both are gone from the schema.
Match the vulkan config to the canonical exporter spec
The published config dropped int8's default flag and declared the encode
input as -1. The canonical schema marks one default per quant-group, and the
other whisper backends declare the encode length as its 480000 maximum.
Exported with the conv1d-as-conv2d lowering, the slice-based STFT magnitude,
hoisted cross-attention K/V and a head-major KV layout. Requires the ExecuTorch
1.4.1 Vulkan runtime from the v0.10.0-libs-1.4.1 artifacts (gelu clamp, reduce
barrier and Adreno local-work-group fixes).
