TSON (Typed Schema Object Notation) is a schema system with immutable, hash-pinned schemas where definitions are themselves data. A single hash can verify an entire chain from document to meta-schema. It is a Unicode-first superset of JSON that is enjoyable to write and includes a compact grammar for schemas. Schemas and data share the same lexer and tooling. Implementations include a Java CLI tool.
