Start by reading the linked Auto-Photoshop-StableDiffusion-Plugin file at typescripts/controlnet/entry.ts to understand the expected /controlnet/version, /controlnet/settings, and /controlnet/filter behavior. Then locate the corresponding server entry points in this repository; the work is done when those endpoints support the plugin's required ControlNet API.
