Apply both corpus findings to the schema

criterion.parent_id — a score commits at any criterion with NO WEIGHTED
CHILDREN. Derived from the rubric, never configured, and neither corpus
document is special-cased: Tarrant's five flat criteria are all leaves;
Friendship's 'Method of Approach' 30 is not scoreable while its 15/10/5
children are. A criterion whose sub-items carry no points stays scoreable
at its own level, because those are requirements mapped through
criterion_requirement rather than children.

requirement.determinable_from_response — false where satisfaction cannot be
established from the response document at all. Gate evaluation excludes
these rather than failing them; treating Friendship's 'two bid copies' as
not_answered disqualifies two of three bidders over a packaging detail.

The scoring rule is mirrored in corpus/validate-truth.py so the corpus and
the code cannot silently disagree. Against Friendship it yields 10 scoreable
criteria of 12, summing to exactly 100.
