📝 WalkthroughWalkthroughThe PR adds safetensors-based conditioning load and save nodes. It adds image-to-image velocity sampling for SD3 and AuraFlow. It adds Marigold V2 post-processing for normals, albedo, and depth predictions. The Marigold extension is registered during built-in extra-node startup. Priority: ➖ Normal Merge Risk: 🟡 Moderate · up to The new sampling mode is unavailable through the SD3 node, and saved conditioning can change shape when reloaded. These limitations affect intended workflows and should be resolved before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@comfy_extras/nodes_cond.py`:
- Around line 124-125: Update the SaveConditioning/ConditioningLoader handling
of tensor-list values so an empty reference_latents list is not silently lost;
either reject empty tensor lists consistently or persist an explicit marker and
reconstruct the empty list during loading. Preserve existing serialization for
non-empty tensor lists and use the relevant Conditioning symbols to keep the
change scoped.
In `@comfy_extras/nodes_model_advanced.py`:
- Line 132: Update ModelSamplingSD3.INPUT_TYPES to declare the optional sampling
selector already supported by ModelSamplingSD3.patch, matching the selector
exposed by ModelSamplingAuraFlow so “img_to_img_velocity” can be passed through.
