//! # metalcraft-flows
//!
//! Reference types and helpers for the **Flow** specification — a serializable,
//! human-authored DAG format for AI agent workflows.
//!
//! See [`SPEC.md`](https://github.com/rust4ai/metalcraft-flows/blob/main/SPEC.md)
//! for the formal wire-format specification.
//!
//! ## Modules
//!
//! - [`model`] — core types: [`FlowDefinition`], [`FlowNode`], [`FlowEdge`],
//!   [`SavedFlow`], [`FlowNodeType`], [`CoreNodeType`].
//! - [`nodes`] — typed views over each node type's `data` payload.
//! - [`walk`] — graph traversal: BFS reachability and handle-aware stepping.
//! - [`eval`] — deterministic predicate evaluation for `conditional` nodes.
//! - [`template`] — `{{path}}` interpolation for string fields.
//! - [`state`] — the running `variables` bag and dotted-path helpers.
//! - [`validate`](mod@validate) — spec conformance checks.
//! - [`store`] — directory-backed CRUD (enabled by the default `fs` feature).
//! - [`log`] — flow execution log entries (enabled by the `log` feature).
