A persisted engine-owned document failed its shape parse — the stored
field tree does not match what this engine's data model declares for the
doc type. Distinct from ModelVersionAheadError (a declared,
governed fence: upgrade the engine); this is UNGOVERNED corruption — a
document no conforming engine wrote — and the read fails hard instead of
letting the malformed value corrupt behavior downstream. The issues name
every offending field path.
