Module document 

Public, fallible DOM layer over the internal panic-contract Ast.

Document is the single public, editable tree entry point. It wraps an internal crate::ast::Ast, exposes read access through NodeRef handles, and edits through fallible methods returning EditError – no panic from the Ast layer ever reaches a Document caller on user-input-driven paths.

Structural validity vs semantic completeness

The wrapped Ast is always structurally valid. Whether the tree contains crate::ast::Node::Error placeholders is a separate, O(1) property exposed by Document::has_errors. A Document produced from a partial parse (containing Error nodes) is read-only.
