  "description": "FablePool milestone-2 canonical encoding vectors. An implementation MUST produce byte-for-byte identical canonical encodings: UTF-8, object keys sorted by Unicode code point, no insignificant whitespace, minimal string escaping (non-ASCII characters emitted as raw UTF-8, not \\uXXXX escapes), arrays in source order. The 'expected' field is the exact canonical text; compare its UTF-8 bytes against your encoder output.",
