First 8-pack on vllm/tess-dual-nvfp4 (both modes, same-night GGUF comparator 116/117). Gap is cli-40-concentrated (−8 off); deterministic packs tie or better (RM-off 14/15 best-ever Tess). Per the pre-registered rule the huginnfork NVFP4A16 weights-only A/B + FP8 precision arm are the next gates. BENCHMARKS vLLM subsection + registry note + compose Quality line; Grok-§3 discriminator results recorded in learnings.
