Release Notes

Fixed

  • Single-header parsing rejects extra headers instead of silently returning
    only the first. Lowering consumes a complete HeaderFragment that owns the
    selected node and its source; folded content and LF/CRLF remain accepted.
  • Standalone header and dependent-tier parsing derive diagnostic coordinates
    from their owned synthetic source rather than separately supplied prefix
    lengths. Header lookup failures carry the caller's text and document origin
    instead of empty context. Existing malformed-header diagnostics are retained.
