Implements a three-phase hierarchical audit architecture: Phase 1 fans out to 200+ agents reading 5-8 files each for detailed findings, Phase 2 detects cross-cutting patterns by analyzing Phase 1 outputs, and Phase 3 synthesizes ranked recommendations. Deployed as a Claude Code slash command that writes structured findings to individual `.md` files in real time, avoiding context compression losses. Scales transparently from 100 to 10,000+ file codebases by pre-filtering relevant files and keeping slice count proportional to audit scope rather than total repo size.
