   Title:   The Vaara Receipt: A Recomputable Receipt Format for Decisions About Autonomous Actions

Abstract:

   This document specifies vaara.receipt/v1, a signed and independently
   recomputable record that binds a decision about an autonomous action
   to the evidence the decision was made on, and optionally to one or
   more external timestamp anchors.  The format is canonicalized with
   the JSON Canonicalization Scheme (JCS) so that any third party can
   recompute its digests and verify its signature without access to the
   issuer.  A decision and the execution receipt that answers it form
   one recomputable pair through the envelope's back link.

   The receipt's trust is root-agnostic: the same record is verifiable
   with or without a hardware trusted execution environment and is re-
   expressible as an IETF RATS Entity Attestation Result.  Downstream
   specifications (a payment rail, a compliance regime, a framework
   integration) define profiles that pin to a version of this document
   and add only their own evidence schema; they do not redefine the
   envelope.  The format described here is deployed, and its receipts
   are independently recomputable from public conformance vectors that
   ship with standalone checkers importing no issuer code.  The minimal
   profile is a governance decision over a single autonomous action,
   bound to the action's own intent with no external rail; it is the
   floor of the format, and a reference library offers a matching
   adoption floor at the API layer as a one-line decorator over the
   governed function.
