      description: 'Creates an unguessable, revocable bearer token (fdrsh_…) over a

        TERMINAL intent receipt (CONFIRMED, FAILED, or REJECTED — in-flight

        receipts are rejected with 409). Only the SHA-256 of the token is

        stored; the token is returned once and cannot be recovered. The served

        projection is sanitized (credential-shaped fields stripped recursively

        and every stripped path disclosed), digest-bound (SHA-256 full + public

        digests), outcome classified, and Ed25519-signed. Requires session

        ownership of the receipt''s parent intent.'

      summary: Resolve a public receipt share (agent JSON or human page)
      description: 'Public, keyless, TOLL-FREE proof-of-outcome endpoint. Returns the sanitized

        receipt, outcome classification with retry guidance, dual integrity

        digests, and the Ed25519 signature block containing the detached

        signature bytes and the exact signed envelope — verify independently

        against /.well-known/farmdash-receipt-key.json. Responds JSON by

        default and a retro no-JS HTML card when Accept includes text/html.

        Revoked shares return 410. Responses are no-store (revocation is

        immediate); a `valid:true` signature flag is a server self-check —

        third parties MUST verify the signature themselves.

        Verification reads are never payment-walled but share the caller''s

        daily booth budget and 429 past it, so spam burns its own bucket.

        Share tokens are unguessable 256-bit bearer secrets with no listing

        endpoint, so enumeration is infeasible. Minting (POST

        /api/v1/agent/receipts/share) remains session- and toll-gated.'
