Plan-time methodology contract for survey/review/report projects. Forces an audit-grade survey instead of a paper-trust summary. Distilled from ~240 reviews (2024-2026) across 9 domain clusters — physics/RMP/Living Reviews, chemistry/materials, biology/medicine narrative + Cochrane SRs, CS/ML/AI, math/Acta Numerica, earth/environment, economics/JEL, engineering/Annual Reviews, plus PRISMA/GRADE/Cochrane protocol literature. Empirical A-grade rate by domain ranges 7% (biology narrative) to 86% (math/Acta Numerica); the discriminator is structural, not stylistic. **Read this BEFORE writing notes/plan.md for any survey-style RESEARCH.md.**
