# LTX-2.3 3-stage distill install manifest — consumable by apply_manifest (src/services/manifest.ts).
# Ground truth: jcd315/comfyui-mcp-muse workflows/ltx23_distill_3stage.json
#   (commits 63f3b2a feat, 6d2ccd2 rename, d087cdf resolution-defaults fix).
# Every model below is referenced by a loader node in workflow.json; URLs verified
# via HEAD request 2026-07-12. Sources: Lightricks (official), Kijai/LTX2.3_comfy
# (transformer-only fp8 split + taeltx preview VAE), Comfy-Org/ltx-2 (gemma +
# heretic LoRA), Aitrepreneur/FLX mirror (split VAEs + text projection, same
# files the sibling ltx-2.3 packs pull).

pip:
  - imageio-ffmpeg   # VHS_VideoCombine needs an ffmpeg for the mux

# Same node set as the sibling ltx-2.3 packs (the workflow derives from the same
# ULTRA ecosystem): LTXVideo (LTXV*/LTX2_NAG/SageAttention patch/ManualSigmas),
# KJNodes (ImageResizeKJv2/SimpleCalculatorKJ/VAELoaderKJ/INTConstant), rgthree
# (Power Lora Loader), VHS (LoadImagePath/VideoCombine), ComfyMath, plus the rest
# of the shared ULTRA toolchain (ResizeImagesByLongerEdge et al.).
