# Concepts

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

- **[Architecture](/docs/scaigrid/scaimind/concepts/architecture)** — How the REST endpoint, the gRPC bridge, the local cache, and the external MindCoordinator fit together.
- **[Training jobs](/docs/scaigrid/scaimind/concepts/training-jobs)** — The five-config submission shape, the lifecycle of a job, lifecycle controls (cancel, pause, resume, retry), and where checkpoints fit.
