A.16:5.8 - Short compound histories

notice -> stabilize -> route -> projection into U.AbductivePrompt and endpoint admission -> reopen -> sketchBackoff -> route can be summarized only when each intermediate move, changed rule, loss, and independent status claim remains reconstructible. Retreat preserves the earlier endpoint result in the history. When comparing histories, do not treat route -> projection and an unsupported cue -> requirement leap as one “formalization speed”; compare the moves, forms, applicable rules, and independent status claims.
