Start by reading related issues #9325, #10989, and #10397, then inspect FluxLoraLoaderMixin's unloading behavior for the cited Flux Canny LoRA. The expected handling of shape expansion and unloading must be clarified before implementation; done should be defined by the agreed behavior and a validating test.
