   Title:   Declared-versus-Observed Measurement Capsules: A Profile for Third-Party Measurement Statements in SCITT
   Author:  Nicholas Templeman
   Name:    draft-templeman-scitt-measurement-capsule-00.txt
   Pages:   16
   Dates:   2026-09-26

Abstract:

   This document defines the measurement capsule: a small, deterministic
   JSON record in which a party that is neither the subject of a claim
   nor a participant in the action it concerns records what the subject
   declared, what the measuring party observed, and the difference
   between the two.  A capsule carries digests of its evidence, a
   measurement state in which "could not be checked" is a first-class
   outcome, and no decision, approval or authorisation.  Capsules are
   identified by the SHA-256 of their JCS serialisation and batched
   under an RFC 9162 Merkle Tree Hash.  The document describes their
   registration as SCITT Signed Statements (RFC 9943), how they refer to
   rather than restate receipts issued under other profiles, and one
   implementation, including where it does not yet match this profile.
