Each starts from lilcheaty's minimax_h3_fl2va_pruned_nvfp4.safetensors and copies, from the matching Ref2VA NVFP4 file, only the FP16 adaln_proj.linear weight and bias for an inclusive, zero-based block range: b15-49 (70 tensors replaced), b20-49 (60), b25-49 (50) or b30-49 (40). Everything else stays FL2VA: the adaln_t_table, final-layer AdaLN and output heads, attention, MLP, normalisation, embeddings, token refiners and all 200 NVFP4 layers. There is no interpolation, dequantisation, requantisation or fine-tuning. A lower start block gives more Ref2VA conditioning; a higher one keeps more FL2VA. b25-49 reproduces the selection in smhfacct's INT8 hybrid, which the author checked tensor by tensor (exactly 50 AdaLN tensors from Ref2VA). This differs from block hybrids that copy whole Ref2VA blocks.\n\nValidation: all four were checked structurally and per tensor and generated video in ComfyUI; b25-49 was tested on both FL2VA first/last-frame and Ref2VA reference workflows with video and audio.
