model_name, sampler_name and scheduler were declared as COMBO outputs, so the
documented wiring failed at queue time with "Return type mismatch between linked
nodes". ComfyUI only accepts a COMBO output into a node that declares its
dropdown as COMBO/IO.Combo, while Load Checkpoint, KSampler and the LoRA Manager
loaders expose their options as a plain list; comfy_execution.validation rejects
any non-string input type there, and a STRING output is rejected the same way.
Declare the three sockets untyped ("*"), the type ComfyUI's own Primitive node
uses to feed widget inputs. Verified with execution.validate_inputs that they now
link into both classic list dropdowns and IO.Combo inputs.
Also corrects the wiring guide, which claimed COMBO was the supported type.
When metadata extraction succeeds but no recognized latent source
provides dimensions (e.g. img2img via VAEEncode), width/height now fall
back to the source image size from the loaded pixels instead of the
synthetic 1024x1024 starter preset. The starter preset for metadata-free
images keeps its fixed size, and explicit overrides still win.
Add Load Image Metadata (LoraManager) to extract reusable prompts,
model references, LoRA stacks, and sampling settings from images.
Prefer saved A1111-style parameters by default, with optional workflow
and subgraph sampler selection. Resolve local model and LoRA names,
report missing resources, and recover extraction failures with explicit
defaults and readable diagnostics.
Include parser, resource-resolution, and node regression tests, plus
usage documentation.
