Use when a user needs to: (1) audit an inherited or undocumented project before migration, (2) compare old and new repositories across tooling, architecture, routing, state, request, styling, CI/CD, or release flow, (3) produce migration deliverables such as audits, maps, diff matrices, plans, pilot scopes, adapter plans, risk lists, or verification checklists, (4) execute or update a specific migration phase such as intake, audit, map, diff, plan, pilot, execute, verify, or cleanup.
