The upscale_model input was at index 5 instead of index 12, causing all
widget parameters to be misaligned. Fixed by:
- Updating link target index from 5 to 12 for upscale_model
- Adding explicit entries for widget parameters in inputs array
- Maintaining correct parameter order per custom node definition

Added example images for testing workflows:
- input_image.png (512x512) - for general upscaling workflows
- input_portrait.png (512x768) - for portrait/face upscaling workflows
Sound Lab's Musicgen_ node outputs AUDIO format that is only compatible with Sound Lab nodes like AudioPlay, not the built-in ComfyUI audio nodes (SaveAudio/PreviewAudio).
SaveAudio was erroring on 'waveform' key - the AUDIO output from
Musicgen_ node has a different internal structure than what SaveAudio
expects. PreviewAudio is more compatible with Sound Lab's AUDIO format.
Files are still saved to ComfyUI output directory, just through
PreviewAudio instead of SaveAudio.

Fixed medium, small, and melody workflows:
- Replaced non-existent nodes with Musicgen_ from Sound Lab
- Added missing links arrays to connect nodes properly
- Updated all metadata and performance specs
Note: Melody workflow simplified to text-only as Sound Lab doesn't
currently support melody conditioning via audio input.

Changed from non-existent nodes to actual Sound Lab nodes:
- Replaced MusicGenLoader/MusicGenTextEncode/MusicGenSampler with Musicgen_
- Replaced custom SaveAudio with standard SaveAudio node
- Added missing links array to connect nodes
- All parameters: prompt, duration, guidance_scale, seed, device
Node is called "Musicgen_" (with underscore) from comfyui-sound-lab.

SD3.5 checkpoint doesn't contain CLIP encoders. Now using:
- CheckpointLoaderSimple for MODEL and VAE
- TripleCLIPLoader for CLIP-L, CLIP-G, and T5-XXL
- Standard CLIPTextEncode for prompts
This fixes the "clip input is invalid: None" error.

Replaced CheckpointLoaderSimple with UNETLoader + DualCLIPLoader.
Replaced CLIPTextEncode with CLIPTextEncodeFlux.
Added proper VAELoader with ae.safetensors.
Added ConditioningZeroOut for empty negative conditioning.
Removed old negative prompt input (FLUX doesn't use it).
Changes match FLUX Dev workflow structure.

Added FLUX VAE (ae.safetensors) to model configuration and updated
workflow to use it instead of non-existent pixel_space VAE.
This fixes the SaveImage data type error (1, 1, 16), |u1.

Node 3 (CLIPTextEncodeFlux) output feeds both KSampler (link 3) and
ConditioningZeroOut (link 8), so the output links array must include
both links.

FLUX models require negative conditioning even though they don't use it.
Added ConditioningZeroOut node to create empty negative conditioning from
positive output, satisfying KSampler's required negative input.

Both CLIP-L and T5-XXL come from the same repo, so they should
be in one entry with multiple files, not two separate entries.

Add CLIP-L and T5-XXL entries with type: clip so they get
linked to /workspace/ComfyUI/models/clip/ directory for
FLUX model usage via DualCLIPLoader.

FLUX models need to be in /workspace/ComfyUI/models/unet/ directory

Remove format-specific parameters from widgets_values array.
Only base parameters should be in widgets_values:
- frame_rate, loop_count, filename_prefix, format, pingpong, save_output
Format-specific params (pix_fmt, crf) are added dynamically by ComfyUI.

- CogVideoX-5b-I2V requires specific resolution (720x480)
- Cannot generate videos at different resolutions
- Update placeholder image to match model requirements
- Add enable_sequential_cpu_offload=true to DownloadAndLoadCogVideoModel
- Reduces VRAM from ~20GB to ~12GB at cost of slower inference
- Widget values: [model, precision, quantization, cpu_offload] = ['THUDM/CogVideoX-5b-I2V', 'bf16', 'disabled', true]
- Necessary for 24GB GPU with other services running
- Create 1024x1024 white placeholder with 'Input Frame' text
- Allows workflow validation without external image upload
- Will be replaced by API input in production use
- Add THUDM/CogVideoX-5b-I2V model entry (20GB, I2V-specific model)
- Add T5-XXL FP16 text encoder for CogVideoX (9GB)
- Add CLIP-L text encoder for CogVideoX and SD3 (1GB)
- Add CLIP-G text encoder for SD3 (3GB)
Note: CogVideoX models are auto-downloaded by DownloadAndLoadCogVideoModel node
Text encoders already linked manually to /workspace/ComfyUI/models/text_encoders/
- Change checkpoint from 'diffusers/stable-diffusion-xl-base-1.0' to 'sd_xl_base_1.0.safetensors'
- Change IPAdapter weight_type from 'original' to 'style transfer' (valid option)
- Fixes validation errors: invalid checkpoint name and invalid weight_type
- Change from 'source venv/bin/activate' to direct venv/bin/python execution
- Use exec to replace shell process with Python process
- Fixes issue where supervisor doesn't properly activate venv
- Ensures all extension dependencies are available
Added setup/comfyui-extensions-deps script that:
- Iterates through all custom_nodes directories
- Installs requirements.txt for each extension into ComfyUI venv
- Provides count of installed/skipped extensions
- Ensures all extension dependencies are met
This makes deployment reproducible and ensures all extensions
load without import errors.
