Use when a teaching or study artifact must get plainer across repeated cold reads; when the same reader stalls keep recurring page after page (a term used before it is defined, a number with no origin, a 40-word sentence, a picture that decorates instead of carrying the mechanism); when a rewrite must keep code, figures and tables frozen while only the prose changes; or when cold reads and Feynman-style rewrites are being delegated to cheaper models and each read should start from what the last one found instead of re-deriving it.
