Per review feedback on ards-project#49 (litzki-systems): the detached JWS in §5.1.1 shares the RFC 8785 (JCS) canonicalization baseline with SOVP-v1's attestation payload (ards-project#48, §5.2.1). Note the shared signing primitive as a composition property — disjoint sections, no normative coupling. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Summary
Adds SOVP-v1 as a documented attestation type in §5.2.1 and §5.2.2, complementing TRACE-v0.2 (runtime governance) and install-manifest (install-time consent).
The layer SOVP-v1 occupies
The four-layer stack that converged in this repo this week:
Each attests a distinct axis. As @imran-siddique confirmed: "What SOVP addresses is the infrastructure the enclave sits on: cluster hardening, network topology, sovereign compliance of the broader environment. Those are distinct axes, not overlapping ones."
