Governing ratifications (written first):
- docs/analysis/problem-solving-lift-strategic-deep-dive-ratification-2026-06-16.md
- docs/analysis/gsm8k-derivation-reader-recognizer-lift-workstream-a-ratification-2026-06-17.md
- generate/derivation/extract.py: lexeme EX passes for fractions/comparatives + refined incidental-only age hygiene (preserves pinned tests + helps proxy cases).
- teaching/admissibility_exemplars/*_v1.jsonl: 30+ new phase_b_seed entries (dcs/rwc/ma/ca/ta/dsnq) with full schema + Workstream A provenance.
- evals/gsm8k_math/train_sample/v1/report.json: rebaselined via runner; 6/44/0 (wrong=0).
- docs/analysis/*ratification*.md + lookback-2026-06-17.md included.
Scope per ratif: reader + exemplar growth + rebaseline + lookback. No sealed, no CLOSE (deferred per posture), 0 wrong preserved.
See ratifs + lookback for full verification obligations, evidence, and test plan.
