/**
* .what = does a domain object class declare `static unique` key(s)?
* .why =
* two independent graph walks decide "recurse into this nested dobj's own unique ref" off the
* same fact: `refByUnique` (walks live instance values) and `buildKeyContract` (walks schema
* shapes). they once drifted on the *condition* that gates that recursion. this one predicate is
* the single source of truth for that gate, so the two walks cannot silently diverge on it.
* .note = accepts a nullish class so callers can pass `value.constructor` directly (a live value's
* constructor may be absent); a class with no `static unique` and a nullish class both read false.
