Evidence claims:
- [upstream_claim] README: V8.0 and later no longer install Impact-Subpack (needed for UltralyticsDetectorProvider) automatically; Python requirements include segment-anything, scikit-image, piexif, opencv-python, scipy, numpy<2, dill, matplotlib; V8.24 requires ComfyUI 0.3.63 or higher. · source: https://github.com/ltdrdata/ComfyUI-Impact-Pack
- [upstream_claim] Since V7.6 automatic dependency installation is no longer supported; manual installs run pip install -r requirements.txt in ComfyUI's own Python environment (python_embeded for Windows portable); install downloads sam_vit_b_01ec64.pth unless an empty skip_download_model file exists in custom_nodes. · source: https://github.com/ltdrdata/ComfyUI-Impact-Pack
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.

- model_weights: license=unknown hosting=unknown redistribution=unknown modification=unknown training=unknown · Downloads a SAM checkpoint at install; detector models for the Subpack are separate. Model files these nodes load or download carry their own licenses; the node code license does not cover them. Not assessed here.
