mamba2_scan_backward kernel reads d_h_enriched [B, SH2] but was passed self.grad_buf [TOTAL_PARAMS] — wrong buffer, wrong size. At batch_size=4096 the kernel read 1M floats from a 582K buffer → 2749 OOB reads. Fixed: use self.bw_d_h_s2 [B, SH2] which is the actual trunk activation gradient from the cuBLAS backward pass. Also increased smoke test batch_size to 4096 to catch scale-dependent OOB. compute-sanitizer: 0 errors at batch_size=4096. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
