- **CONFIRMED:** node 337 splits RGB/CMY/B/W masks from node 338; MaskToImage nodes expose mask previews/consumers.
- **CONFIRMED:** people masks originate from Florence2 550 → coordinates 114 → SAM2 115 → grow 144 → blur 146. Cut/Paste nodes 449/429 perform the first composite; 499–510 separate components and perform inpaint composite.
- **CONFIRMED:** architectural detail mask originates from prompt 591 → Florence2 580 → coordinates 584 → SAM2 585. Node 775 composites the selected base/source using this mask; nodes 747/749 plus 754 produce conservation masks.
- **NOT CONFIRMED:** no explicit `InvertMask` node is active in this graph; inversion inside third-party node implementations cannot be established from JSON.
