Evidence-driven dissection of an existing service, written plan, or codebase area. Interrogates every entity (table, field, component, endpoint, module, boundary) against ground truth from multiple sources at once, red-teams each verdict devil's-advocate style, and arrives at the minimal-build optimization plan. Runs…
