      "description": "Convert a document locally, bind the conversion into a receipt, and independently verify the receipt. Stage 1 converts Markdown to HTML and plain text (art-189), or tabular data across CSV, JSON, and Markdown tables on the tabular branch (art-190). Stage 2 binds the input digest, converter identity, parameters, and output digest into a canonical receipt (art-191). Stage 3 recomputes the binding and re-hashes the files to return a valid, binding_mismatch, digest_mismatch, or malformed verdict (art-192). Every stage produces a SHA-256 execution hash. Zero network, zero PII.",
