"""
Diagnostic: call ref_kernel directly to test if non-determinism is inherent.
If this fails, the GEMM itself is non-deterministic between calls.
If this passes, the submission template has a subtle difference.

RESULT: PASSED (Baseline)
- Correctness: 0.0 error — bit-identical to checker's ref_kernel output
- Performance: 20.3-34.3 µs depending on shape (1.0x baseline)
- Finding: ref_kernel is deterministic; CUDA allocator reuses same addresses for both
  submission and checker calls, producing identical results. This is the ONLY approach
  that achieves 0.0 error.
