Bug 9: padded_x_sf was sized for num_experts*128 rows, but with 8192 tokens and top_k=6, the actual padded row count can exceed 6144. Also: - Pass top_k and max_num_tokens from deepseek_v4.py (was defaulting to 8/8192) - Phase 2 of scale assembly now handles experts with >128 tokens (multiple 128-row chunks) - Remove debug prints
