+// Known-answer check for MXFP4 weights on HRX: GET_ROWS of MXFP4 rows must equal ggml's dequantize_row_mxfp4
+// bit for bit (the E8M0 half scale is a power of two and every E2M1 value is exact). Rows use the exponents
+// 120, 127, 134 and the edges 0, 1, 2, 254; every block holds all 16 codes in both nibbles. Exponents 0 and 1
+// have f32 subnormal scales (2^-128 and 2^-127), which the GPU kernels flush to zero, so those rows' values
+// (at most 12 * 2^-127) may come back as zeros of the same sign; every other value must match exactly. The graph runs on the HRX device itself (no scheduler, so no CPU fallback), and the HRX
+// dispatch plan for it must contain the get_rows kernel.
