Concepts

Core ideas worth modelling before you write code. Each topic is self-contained — skim the one you need.

• Architecture — How the ScaiGrid wrapper sits over the ScaiCore language runtime — what the wrapper owns, what the language owns, where the seam is.
• Checkpoints — The data model behind ScaiCore's human-in-the-loop pauses — what a checkpoint is, who it's assigned to, how it expires, and how it resolves.
