Establish the grammatical-coverage eval lane with 13 English v1
constructions (simple declarative, negation, conjunction, disjunction,
embedded clause, relative clause, quantification, tense, aspect).
- contract.md with scoring rubric and pass thresholds
- runner.py conforming to framework interface
- dev set: 41 cases (baseline: 24.4%, only C01/C10 pass)
- public v1: 36 cases (baseline: 19.4%, only C01/C10 pass)
- holdout and realizer engineering are next
The realizer currently handles only simple present-tense SVO declaratives.
Negation, conjunction, embedding, quantification, tense, and aspect all
need engineering work.
