Steps completed (per abstract-painting-kitten.md): 1. FIX edge_blur_amount float truncation: int→float in MaskParams + removed int() casts 2. Wire invert_mask: INPUT_TYPES, method signatures, Pydantic validation, alpha inversion applied in both AutoGrabCutRemover and GrabCutRefinement success paths 3. Add [B,6] bbox_metadata tensor output to AutoGrabCutRemover RETURN_TYPES 4. nodes.py: @torch.no_grad() on remove_background + batch_remove_background; all .float()→.to(dtype=torch.float32) 5. Structured tests/ suite: conftest.py, test_grabcut_processor.py, test_grabcut_nodes.py, test_nodes.py, test_validation.py Verification: - 48/48 new tests pass - 6/6 original test_grabcut.py tests pass - 4/4 node import test pass - 0 flake8 E9/F63/F7/F82 errors - edge_blur_amount=1.7 correctly stores as float (not truncated to 1) BREAKING: AutoGrabCutRemover RETURN_TYPES changed from 5→6 (bbox_tensor added)
