Backstep is a memory for hands-on work, the rewind button for the real world. The problem: anyone who repairs or maintains their own gear knows the moment. You took something apart weeks ago, and the knowledge of how it goes back together has already evaporated. Today's workaround is scrubbing forty minutes of phone footage by hand, hunting for the frame where the tiny screw went. Film a teardown once. Backstep watches the recording and builds an object-state memory: every part, the order it came out, and the state of the assembly at each step. Later, standing over the pile of parts, you ask "Where did I put the drive bay screw?" and the timeline scrubs to the exact frame, with the part's region painted on it. Ask "How does this go back together?" and the manual assembles itself in reverse from your own footage. Guide mode then walks you through reassembly step-by-step, and Check My Work compares a photo of your bench against the target state. Every answer is a citation, validated deterministically against the memory before it is shown. If it wasn't seen in the footage, Backstep refuses instead of guessing.
