+/// we can provide a **single** global `NavigationStack` shadow function, rather than two separate overloads.
+/// This completely eliminates "Ambiguous use of NavigationStack" errors when developers use the standard
+/// `NavigationStack` API.
+public protocol _UDFBindablePath {

+    ///
+    /// - Parameters:
+    ///   - path: The binding to the navigation path.

+/// A global shadow function that overrides the standard `NavigationStack` initializers to emit a compile-time warning.
+///
+/// ## Why this exists
+///
+/// Using SwiftUI's native `NavigationStack(path:)` with a binding projected from UDF state causes
+/// unstable binding identities. This instability forces SwiftUI to speculatively re-evaluate the
+/// navigation tree on every state update, leading to phantom `@StateObject` allocations and spurious
+/// `onContainerDidLoad` / `onContainerDidUnload` lifecycle triggers.
+///
+/// This function intercepts those calls and issues a deprecation warning, instructing developers to
+/// switch to `NavigationStackBound`, which encapsulates the native stack while stabilizing the binding identity.
+///
+/// - Parameters:
+///   - path: The binding to the navigation path (either `NavigationPath` or `Array`).
+///   - root: The root view of the stack.
+/// - Returns: A standard `SwiftUI.NavigationStack` (with a compiler warning).
