Build programmes safely as graphs
Plan new deliveries from one or more Tocco programmes as versioned graphs, validate them and materialise them in a controlled way.
Status: in acceptance. Shared deliveries are created exactly once; node-level rules govern billing items, grading structures, learning objectives, questions, answers and relatively rescheduled appointments. Registrations and lecturer bookings are never copied. The instance calendar belongs to the studio; the global calendar remains a separate module.
