REWIND

REWIND watches you assemble furniture and checks each step against the manual, live. A two-stage gate runs SAM 3.1 segmentation plus local part checks, then Muse Spark Open (open weights, via Baseten) audits the frame against the manual step. It fails closed: when unsure it says STOP or 'can't tell', never a fake pass. When a step passes, Muse Wonder ticks it off the manual checklist. Demoed live on a real Zinus bed frame: the bracket with its blank face up is stopped, and the correct face passes and ticks step 7. Inputs: phone camera, photo/video upload, or test images. Everything was built during the hackathon (Oct 26 onward; repo created Oct 28).
