      summary: One safe action through the full governed NOMOS chain - signed, verifiable…
      description: 'Full-Chain Governed Verification: run one safe, read-only machine action through the complete NOMOS Machine Economy Trust Chain and get back a cryptographically verifiable execution proof. The call binds your payment, a stated intent, a pinned capability and offer, a NOMOS admission decision (which enforces current CISA-KEV-derived OracleNet security-freshness evidence), the execution and the response bytes into one Ed25519-signed execution receipt you can verify yourself against the public JWKS (https://feedoracle.io/.well-known/nomos-execution-jwks.json). Read-only; no asset movement besides the x402 payment itself. Request size limit (separate from schema validation): the request object is rejected when its re-serialised JSON exceeds 2048 UTF-8 bytes; this is measured on the parsed-and-re-serialised object, so whitespace and key order in the raw HTTP body do not count towards it. Claim boundary: EXECUTION_BOUND_PROOF (estate-signed evidence, not an independent third-party attestation, not a certification).'

It carries no caller authority - it neither selects nor widens the executed capability, and the value is discarded after validation; execution always uses the server-side capability constant.'
