Why: The approved model samples showed unsupported approval claims, repeated source input and no final answer before the run budget stopped.
Evidence: The design cites the preserved A01 provider usage, persisted findings and independent sample audit without claiming new model validation.
Impact: Define a reviewable source, claim and final-reserve revision while keeping code, paid trials and merge gated.
