Abstract:

   This document defines the Cedulon Protocol, an audit layer for agent-
   to-agent commerce.  Payment rails such as HTTP 402 flows (x402) and
   mandate protocols (AP2) already move value.  They do not, by
   themselves, produce a fail-closed policy check and a signed spend
   receipt that a verifier can reconcile against a rail extract.
   Cedulon specifies a Trade Manifest (signed offer before payment), a
   Policy Decision Point with default deny, a Spend Receipt (COSE/CWT
   claim set after a gated payment), epoch checkpoints, and rail-extract
   reconciliation.  The reconciliation shows that no settlement on the
   extract lacks a receipt and no settled receipt is absent from the
   extract.  That result is unconditional only when the verifier pins
   the rail key out of band and states the period under audit; otherwise
   the document requires it to be reported as conditional.  It also
   defines a Dispute Evidence Bundle (evidence, not an award) and
   optional SCITT anchoring.  Cedulon is not a competitor to x402 or
   AP2; it sits above them.
