+`RepairGame` reads the active mission step from the store and writes transitions through generic actions such as `setMissionStep` and `completeMission`. Shared repair ids, mission steps, and runtime guards live in `src/types/gameplay/repairMission.ts` so static mission config does not depend on the Zustand store.

 Mission-specific behavior stays in `src/data/gameplay/repairMissions.ts`: each mission can define its broken nodes, placeholder targets, scan duration, and reassembly duration without adding mission branches to `RepairGame`.
