CAT-K6: a version is reviewed in parts: the head and each section, a part judged again only when its text or what it names changes

One judgement per part with no tools, at most two at once; a section is read with its frame (the clauses and records it
names and the digest of its Context), so a usual revision judges only what changed. The latest approval of each part is
kept in the head and carried to the next version; a part that could not be judged keeps the others' verdicts and is the
only one asked again; reviewed is said once per version and each verdict as part-reviewed on the stream reviews. A part
in flight is a key of the state asked. A version is accepted when every part approves; findings name their part.

Issue 1966.
