Summary:

Ulterior Motive

Unblock Swin V2's stored query/key/value biases and attention logit scales.

Rationale

What: Add aten.clone.default and aten.clamp.default to the existing stored-input prepack list.

Why: Clone expects a tensor rather than a TensorRef. Clamp also needs a bound input resource; leaving its stored input as a reference can leave the shader descriptor unwritten.

Details

  • Reuse the existing explicit prepack path without changing either kernel.
  • Cover both operators in the prepack pass and numerical engine tests.
  • Preserve the existing mutation guards and all nonstored-input paths.
