//! Explicit application-owned normalization and validation composition.
//!
//! This module does not perform database admission, persistence, retries, or
//! accepted-schema constraint evaluation.

/// Consuming normalize-then-validate convenience for application values.
///
/// The value is normalized first. Validation runs only if normalization
/// succeeds, and the normalized value is returned only after both traversals
/// succeed. The method consumes `self`, so it neither clones the value nor
/// creates a second callback owner.

    ///

    /// Returns a typed [`VisitorError`] from the first failing stage. Use
    /// [`VisitorError::operation`] to distinguish normalization from
    /// validation without inspecting diagnostic prose.
