DEFONEOS BFT Council Architecture Pack — UK Sovereign Defence OS

1. WHY THE BFT COUNCIL GETS A DEDICATED ARCHITECTURE PACK

The DEFONEOS Byzantine Fault Tolerant (BFT) council is the governance heart of the entire sovereign AI substrate. It comprises 33 autonomous agent nodes — each with its own cryptographic identity (Ed25519 keypair), its own evaluation model, and its own voting weight — that collectively govern every DEFONEOS decision: SEAL issuance, MCP certification, policy enforcement, evidence chain attestation, and red-line enforcement. The council operates on a modified Practical Byzantine Fault Tolerance (pBFT) consensus protocol with the following parameters: N=33 agents, f=10 maximum Byzantine faults tolerated (⌊(N-1)/3⌋), quorum Q=23 (2f+1 minimum for consensus), leader rotation by VRF (Verifiable Random Function), and Ed25519 signature aggregation for commit certificates. The council is structured as a "Liquid-KAN Council" — agents can delegate their votes to trusted peers (liquid democracy), enabling emergent specialisation. The council also maintains a human-owner seat (Nick Templeman, SC-cleared) with veto power but no unilateral issuance authority. The architecture ensures that no single agent, no single human, and no colluding minority can subvert the governance standard.

All council decisions are BFT-signed (Ed25519 / RFC 8032 / 2026-Q3 rotation) and curl-verifiable. Architecture specification sourced from CSOAI.org governance registry (2026-Q1).

5. THE 5-STEP DEFONEOS BFT COUNCIL ENGAGEMENT MODEL

DISCOVERY: Sovereign audit of existing AI governance structure — decision-making processes, accountability frameworks, audit trails, compliance status. No data leaves the buyer's network.
PROVE: Deploy DEFONEOS BFT council probe in sandboxed environment — demonstrate council vote on mock SEAL issuance, Ed25519 signature verification, quorum attestation, red-line enforcement.
PILOT: 30-day single-deployment pilot — stand up a 7-agent mini-council, run 10 governance votes, demonstrate liquid democracy delegation, issue 3 provisional SEALs.
SCALE: Full 33-agent council deployment — every AI decision governed by BFT vote, continuous red-line monitoring, SEAL portfolio for all systems, allied federation.
SOVEREIGN: Full DEFONEOS governance stack — national AI governance council, BFT-attested decisions for every government AI system, immutable audit ledger, allied interoperability.

6. RED LINES — BFT COUNCIL DEPLOYMENT BOUNDARIES

Red line	Why
No SEAL issuance below quorum (23/33) — ever	Byzantine fault tolerance — any decision below quorum is invalid and must not be published
No bypassing the human-owner seat for SEAL issuance or revocation	Human governance — the SC-cleared owner seat must be live for any credential lifecycle event
No disabling the red-line enforcement engine	Safety invariant — the kinetic/surveillance detection engine must run on every proposal without exception
No council agent operating without an Ed25519 keypair	Cryptographic identity — every agent must have a registered, verifiable identity for vote provenance
No ledger modification or deletion — append-only forever	Audit integrity — the governance ledger is immutable; corrections require new entries, never edits
