Summary

• Replays the Cosmos3-Edge TensorRT-LLM Reasoner cookbook onto current main, after the generate-media skill migration in cosmos3-generate-media skill (cookbook → skill migration) with eval-derived fixes, cosmos3-skill-authoring guide, opt-in skill-eval CI #324.
• Cosmos3-Nano and Cosmos3-Super stay on nvcr.io/nvidia/tensorrt-llm/release:1.3.0rc22.
• Cosmos3-Edge is served from a TensorRT-LLM main build at or after 39a44fab (the merge of [None][feat] Add Cosmos3-Edge Reasoner support TensorRT-LLM#20307). Release images through v1.4.0rc1 do not include Cosmos3EdgeForConditionalGeneration.
• Keeps the cosmos3-generate-media skill (cookbook → skill migration) with eval-derived fixes, cosmos3-skill-authoring guide, opt-in skill-eval CI #324 distilled-reference link, the FP8 quantization note, and the separate TensorRT-Edge-LLM sections.
• Supersedes Add Cosmos3-Edge to the TensorRT-LLM Reasoner cookbook #299.

Testing

• The notebook content has been reviewed in Add Cosmos3-Edge to the TensorRT-LLM Reasoner cookbook #299. Its process, port, and Docker checks were already run locally.

Could we please make the linked source-build steps select a revision that actually includes Edge Reasoner support? This paragraph correctly requires 39a44fab or newer, but the linked TensorRT-LLM Generator instructions still run git checkout cc63e66daf52644f1441e117bb7ba67d20566016 (README line 202). I checked the upstream commit ancestry: cc63e66 is an ancestor of 39a44fab and predates the Edge Reasoner merge, so following that build block literally does not meet this prerequisite. An explicit Edge-specific checkout override at 39a44fab or newer, or corrected linked instructions, would avoid that contradiction while keeping the Nano/Super release-image path unchanged. Thank you!
