This document describes the current wire contract between native Schist and Schist Cloud so that independent providers and clients can interoperate. MUST denotes a requirement for the described operation; SHOULD denotes recommended behavior. Optional extensions do not become mandatory merely because Schist Cloud implements them. Service limits, screening decisions, billing, storage vendors and hosting choices are provider policies, not requirements to use a particular implementation.
