Implement the 031-quality-gates-hygiene feature that strengthens automated quality gates by adding pnpm audit to the check script, v8 coverage thresholds with per-directory auto-ratchet (domain 96%, adapters 71%, persistence 87%), Biome cognitive complexity enforcement (max 15), and keyboard accessibility for the combatant row, while cleaning up all blanket biome-ignore comments, refactoring 5 overly complex functions into smaller helpers, and codifying the early-enforcement principle in the constitution and CLAUDE.md
