Public Verification Registry: Three Live Cadence Records

Registry state verified: 2026-11-12 · Key ID: grai-seal-1 (ECDSA P-256).

Why no draft text appears on this page. Every receipt at grai.page/verify/:hash stores the SHA-256 commitment of the draft, the measured cadence score, the sentence-length burstiness (CV), the rule pass count, and the ECDSA P-256 signature status. Zero client prose is stored on our servers. That privacy boundary is the product.

1. The Three Public Reference Records

These three records live in the production Cloudflare KV registry and can be inspected by any client or agent at their permanent SHA-256 URLs.

Note: Record 01 is a synthetic reference sample written in a short declarative register, not a direct quotation from Paul Graham.

2. How Zero-Prose Verification Works

When a ghostwriting studio or executive team seals a draft under the Agency Verification Protocol, the worker audits the text in volatile memory against the eight structural rules and the CV ≥ 0.32 sentence-length burstiness floor.

If the draft passes, the server signs the metadata commitment with ECDSA P-256 and writes only the SHA-256 hash, the score, the CV, the rule count, and the agency reference to the registry. If a draft fails the gate, the server refuses to issue a cryptographic signature (not_issued_failed_gate). In both cases, the client prose is discarded immediately after the hash is computed.

Issue client-verifiable cadence receipts on every retainer deliverable.
