Provenance and exclusions

This snapshot was curated on 2026-08-12 from an H3 optimization worktree. It preserves source and compact measurements while removing host-local and bulky artifacts.

Upstream revisions

Component Upstream Revision License note
ComfyUI https://github.com/Comfy-Org/ComfyUI.git 6db4fa2fcd38a92d4e0364c917cd8503620e2a74 GPL-3.0; source overlay includes modified upstream files.
comfy-kitchen https://github.com/Comfy-Org/comfy-kitchen.git 5aab6c4bdb2bb73f4021277a58cc62d6185a7aed Apache-2.0; native NVFP4 packing/layout follows v0.2.27 CUDA code.
SageAttention https://github.com/thu-ml/SageAttention.git d1a57a546c3d395b1ffcbeecc66d81db76f3b4b5 Apache-2.0; the promoted Q deployment includes a narrow source patch and the earlier source overlay retains its license.

Copies of the ComfyUI and comfy-kitchen upstream license texts are under third_party_licenses/. They describe upstream portions; they do not declare a new repository-wide license for original campaign work. No LICENSE file is added because ownership and redistribution terms for that original work were not provided.

Included

  • The modified H3 ComfyUI source overlay and tests.
  • Custom H3 attention/profiler nodes and a path-neutral timing runner.
  • Triton and CUDA kernel source, loaders, build files, and structural tests.
  • Promoted Q deployment patches/manifests and compact qualification receipt.
  • Five-attribute static hook-certificate source/tests and an explicitly held cross-block candidate.
  • Small correctness/timing JSON and text profiler summaries.
  • A serving-default configuration with no credentials.

Intentionally excluded

  • Model checkpoints, weights, quantization sidecars, safetensors, and hashes that reveal machine-local storage layout.
  • Native .so files, cubins, objects, CMake caches, and JIT/build trees.
  • Raw profiler traces, caches, generated contact sheets, images, audio, videos, public-site assets, prompts, and reference concepts.
  • Calibration artifacts bound to a specific private concept or source path.
  • Queue receipts, paused queue state, absolute host paths, shell history, credentials, tokens, and environment secrets.
  • Full third-party source checkouts; exact upstream URLs/revisions are recorded above instead.

The source queue file paused_h3_queue_20260810.json was not read, modified, or copied into this repository.
