Stat Block Validator

Audit and validate D&D 5e 2024 monster stat blocks for mechanical correctness, format conformity, and internal consistency. Five sequential checks: (1) format compliance against MM 2024 layout, (2) arithmetic validation (modifiers, saves, attacks, AC, HP), (3) CR math audit (offensive DPR × 3 rounds + defensive effective HP + AC), (4) action economy audit (multiattack, recharge, legendary/lair/regional/mythic actions), (5) trait vocabulary audit (2024 phrasing, official conditions, no 2014 syntax). Produces a structured defect report with severity (Critical / High / Medium / Low) and corrected stat block. Use on "validate this stat block", "audit my monster", "check the CR on this", "is this stat block legal 2024", "verify monster math", "audit homebrew creature", "valide ce bloc de stats", "audite ce monstre", "vérifie le CR". Boundary: VALIDATES existing stat blocks (use monster-creator to design new ones). Targets D&D 5e 2024 exclusively (not 2014, not PF2e, not OSR — those need different audit patterns once warranted). One stat block per call. NOT for PC builds, NOT for pure-narrative NPCs with no statblock, NOT a balance review ("your CR 5 monster has CR 7 math" yes; "your CR 5 monster is no fun to fight" — that's editorial, use ttrpg-supplement-reviewer).
