Non-Negotiable Evidence Rule
Use skills/model-optimization/model-pr-diff-dossier/SKILL.md as the production bar.
Every PR cited for this family must be based on diff reading, not only PR titles.

Current Main Summary
- Nemotron is a hybrid family: attention, Mamba, MoE, MTP, and VL all intersect.
- Because of that, graph execution, cache dtype, and quantized MoE correctness are the primary risk areas.
Key Landed PRs
- #18863
NemotronH support: Initial NemotronH landing in vLLM. - #25863
Add MoE support for NemotronH: Extended the hybrid family to routed experts. - #33726
Nemotron-H MTP and Mamba Speculative Decoding Support: Opened the MTP / spec-decode path. - #36803
E2E Nemotron-3-Super tests: Added direct Super-family regression coverage. - #37803
Enable NemotronHPuzzle + NemotronHMTP: Expanded hybrid and MTP coverage for the family.
Validation Lanes
- Startup on the current vLLM mainline checkpoint.
- Re-run the parser, quantization, MTP, or multimodal lane that matches this family.
- Re-check tests after touching loader or processor code.

Run an autonomous Humanize-governed vLLM SOTA performance loop for one LLM model: first perform the fixed fair vLLM/SGLang/TensorRT-LLM deployment search and benchmark, then start one RLCR loop that repeatedly decides the gap, profiles the current bottleneck, runs layer/kernel pipeline analysis, patches vLLM code, optionally uses ncu-report-skill for kernel evidence, and revalidates until vLLM matches or beats the best observed framework under the same workload and SLA.
