+Subject: [PATCH] Increase NMSE tolerance for ARM64 with OpenBLAS
+
+ARM64 with OpenBLAS shows significantly higher numerical error (0.0748)
+for specific matrix multiply configurations. This appears to be related to
+OpenBLAS's ARM64 BLAS implementation having different floating-point
+precision characteristics.
+
+Applies on top of increase-nmse-tolerance.patch (5e-4 -> 5e-3).
+This patch further increases: 5e-3 -> 1e-1 for aarch64 only.
