Concepts#

Orchard has a small vocabulary. Learn these terms and the rest of the system follows naturally.

• Scenario — a top-level, runnable description of a desired state.
• Component — a reusable unit of state that scenarios compose.
• Provider — the runtime that turns a declaration into side effects (Postgres rows, HTTP calls, shell commands).
• Wiring — how outputs from one action flow into the inputs of the next, and how Orchard derives the execution order.
• Plan vs run — the two execution modes, why they exist, and what they guarantee.
• Lifecycle and teardown — run records, lifecycle { teardown { } } blocks, and orchard teardown.
