- --pp with gpt-oss now fails with a clear message instead of a
cryptic missing-weight panic inside the Qwen3-only PP engine.
- Sparse GEMV wrappers assert K%16==0 (FP8) / K%32==0 (MXFP4) — the
uint4-vectorized kernels would silently drop a tail otherwise.
- Document the topk_ids buffer holding i32 under an F32 dtype label
(DType has no I32).
- Drop unused imports/locals and the cuBLASLt scale-mode constants
orphaned by the strided-batched FP8 rework (e631a71).
