- **CONFIRMED:** upscale model `4x-UltraSharp.pth`; user factor node 154 = 3.
- **CONFIRMED:** Ultimate SD Upscale node 833 is bypassed (`mode=4`). Stored settings: upscale factor 2, steps 4, CFG 1, `euler`, `beta`, denoise 0.22, mode `Linear`, tile 1024×1024, padding 16, mask blur 32, seam fix `None`, seam denoise 0.25, seam width 64, seam padding 16, seam mask blur 16.
- **CONFIRMED:** associated sizing/overlay nodes 832–851 are also bypassed. **INFERRED:** current graph therefore does not perform this upscale section; output resolution follows the upstream FLUX decode unless bypass handling of a third-party node differs. Runtime resolution is **NOT CONFIRMED**.
