• data.json-repair

  Repair caller-supplied malformed JSON by safely removing an outer Markdown fence, comments, single-quoted strings, unquoted identifier keys, Python literals, and trailing commas, with transformation hashes and strict rejection of duplicate keys or non-finite numbers.

• data.schema

  Create and generate a nested JSON Schema Draft 2020-12 contract by inferring field types and required fields from representative JSON, CSV, TSV, JSON Lines, or YAML records, with equivalent CSV/TSV numeric and null inference, input evidence, and non-enforcing observed bounds.

• data.schema-validate
