/**
 * Minimum requirements for each maturity level.
 *
 * RFC-001 v1.1 (effective 2026-04-12) splits the quality bar:
 * - experimental: 3/3/0 — low barrier for community contribution. OWASP,
 *   MITRE, evasion tests, and FP docs are encouraged but NOT required.
 *   The upgrade pipeline adds these during promotion to stable.
 * - stable: 5/5/3 — production-quality bar with verified provenance,
 *   OWASP + MITRE mapping, evasion tests, and wild validation.
 *
 * Rationale: VirusTotal doesn't reject "low quality" samples — everything
 * gets in. Sigma experimental is loose. A strict experimental gate kills
 * community contribution velocity. Data velocity > data purity at scale.
 *
 * See docs/proposals/001-atr-quality-standard-rfc.md §1 and §3.
