Expert, once
The reference recording.
Film an expert doing a hands-on task. Apprentice turns it into a procedure, then watches anyone's attempt and points at the exact fold, part or edge that went wrong.
Muse Spark watches the expert once and writes the procedure: every step, what done looks like, the usual mistake.
It logs what the learner actually did before it sees the procedure, so it can't talk itself into steps that never happened.
SAM 3.1 masks the exact part to fix, side by side with the expert. Or go live and get coached out loud.
