//! # dpcs
//!
//! Reference implementation of the [Data Pipeline Contract Standard](../SPEC.md) (DPCS).
//!
//! Initial processing pipeline:
//!
//! ```text
//! DPCS Document -> Parser -> Canonical Object Model -> Validator -> Diagnostics
//! ```
//!
//! [`SPEC.md`](../SPEC.md) is the authoritative source of truth. When implementation
//! details are ambiguous, this crate prefers the smallest conservative behavior.
//!
//! # Example
//!
//! ```rust,no_run
//! use dpcs::{parse_yaml_file, validate};
//!
//! let contract = parse_yaml_file("pipeline.dpcs.yaml")?;
//! let report = validate(&contract);
//! assert!(report.is_valid());
//! # Ok::<(), dpcs::Error>(())
//! ```
