 `Save Image Dumas` leaves `folder` empty to use ComfyUI's output directory. `name` feeds `%input%` and `name_2` feeds `%input2%`, so a pattern like `project/%input%_%input2%_%counter%` can combine two upstream strings into the saved filename.
 
+`Dumas Strip Iteration Suffix` only strips a final numeric suffix. Names like `my_asset_final.png` are left untouched, while `my_asset_012.png` becomes `my_asset.png`.

 ## Roadmap
 
 This repo is intended to grow into a broader set of Dumas-branded generic utility nodes, including JSON helpers and adjacent data-manipulation tools.
