MCP server for a personal voice profile: corpus, fingerprint, and draft-checking tools.

Verified, citable world numbers right now, each with a public tick and SHA-256 fingerprint.

Enables vendors to run a declared check battery against their own MCP server, emit sealed Assay-format scorecards with evidence hashes and environment fingerprints, and have a local verifier re-run a random sample to issue counter-signed verification receipts.
