Review finding on the #332 fix: rendering --folds from the fold-registry roster removed fold_vocabulary()/FoldSchema's last production consumer, leaving a second, unsurfaced source of fold docs whose wording had already diverged from the registry. The table and its two tests are gone; the discipline they carried moves onto the surviving surface: the registry tests now doc-gate every roster entry (C29 entry seam) and pin the bind/output prose inside each doc line against the entry's executable binds_at/output rules, so the roster cannot drift from what the wiring enforces. refs #332
