Abstract:

   This document specifies the Attestation Reconciliation Protocol
   (ARP), a deterministic, bilateral, minimum-disclosure mechanism for
   reconciling verification claims against a plurality of sovereign
   authoritative registers without raw register records leaving their
   data-residency jurisdiction.  ARP extends the SCITT (Supply Chain
   Integrity, Transparency, and Trust) architecture to cross-sovereign
   claim reconciliation.  A reconciliation server canonicalises a
   structured claim, binds the identity of the requesting principal --
   including, where the requester is an autonomous agent, a friend-or-
   foe determination of that agent's verifiable principal binding --
   projects the claim through register-specific controlled projection
   functions producing the nearest permitted ancestor predicate
   supported by each addressed register, transmits register-specific
   ciphertexts, receives partial attestations whose payload discloses,
   of the subject, only a verdict, an optional divergence axis, the
   applied profile parameters and a query binding digest, aggregates
   those attestations under a verdict arithmetic the deployment's policy
   resolves, committing each register's contribution to a Merkle tree,
   and seals the resulting reconciliation output against a policy-
   version hash.  An append-only cross-jurisdictional settlement-layer
   ledger records digests and structural metadata, with no claim,
   register-record or principal content.  The protocol supports
   retroactive re-evaluation of historical reconciliations under updated
   pattern libraries or policy versions without bilateral renegotiation,
   and a cryptographic-primitive-upgrade path including post-quantum
   primitives.  This revision adds a normative binding to the SCITT
   Reference APIs, register data-format profiles for beneficial-
   ownership, corporate-registry, customs and consolidated-sanctions
   formats, and a source-data version binding that makes a change in a
   historical verdict attributable to a change in policy or to a change
   in the underlying published corpus.
