migrate
Migrate a Gemini AI Studio prototype into the substrate kernel. Expects prototype/ (Gemini Build export) alongside a scaffolded substrate project. Spawns domain/backend/frontend architects in parallel to analyze the prototype against substrate doctrines, drafts Convex schema + functions from inferred data shapes, moves components into src/ with doctrine alignment, wires Clerk+Convex providers, and presents a migration plan for approval before executing. Invoke after /substrate:init + Gemini handoff, before /substrate:deploy.
