0. Scope & Method
This page answers 38 due-diligence questions that buyers (MOD, NATO, AUKUS primes, allied procurement offices, regulated enterprises) ask when evaluating DEFONEOS for procurement. Each answer carries a 1:1 evidence pointer to a public artefact on csoai.org, with SHA-256 anchor and last-FRESH tick.
Categories: §A Governance (Q1-10) · §B Security & Integrity (Q11-20) · §C Compliance & Audit (Q21-30) · §D Procurement & Operations (Q31-38). Cross-walk: EU AI Act Art. 9/15/17 · GDPR Art. 22/35 · NCSC CAF · ISO 27001 A.5-A.18 · ISO 42001 · JSP 936 · NIST AI RMF.
§A — Governance (Q1-10)
Q1. Who owns DEFONEOS? What is the legal entity?
DEFONEOS is built and certified by CSOAI Ltd (UK Companies House 16939677), trading as MEOK Sovereign AI Labs. Single founder/owner: Nicholas Templeman. UK-sovereign, no offshore holding. Owner-seat cosign is constitutional doctrine.
Q2. How is the 33-agent BFT Council composed?
33 agents across 5 rings — R1 owner-seat (1, Nick, cosign-gate) · R2 founders (4) · R3 senior council (8) · R4 standard council (12) · R5 observers (8). 5 motion classes with quorum thresholds STD 23/33 · REDLINE 27/33 · CONST 30/33 · UNANIMOUS 33/33 · EMERGENCY 17/33.
Q3. What authority does the Council have over AI behaviour?
Council can issue red-line vectors (binding scope exclusions), revoke DEFONEOS-SEAL credentials, ratify SBOM policy, and approve pen-test cycles. 142 motions to date — 100% approval rate, +5.4 avg margin, 0 owner vetoes ever exercised.
Q4. What is the owner-veto / kill-switch mechanism?
R1 owner-seat holds a constitutional cosign-gate (every motion requires owner signature). Additionally, EMERGENCY motions (17/33) carry a 24h sunset clause. Owner can also issue a unilateral owner-veto motion that supersedes any prior motion (0/142 ever exercised).
Q5. Are Council members independent of vendor?
R5 observers (8 agents) are deliberately non-employee and may include external buyer representatives, regulator liaisons, and academic observers. R2-R4 are CSOAI employees or contracted agents under NDA. R1 is sole owner.
Q6. How is Council voting audited?
Every motion is anchored to a SIGIL with Ed25519 signature, BLAKE3 hash, R1 cosign, 3-witness fingerprint, and pointer to red-line vector coverage. Audit trail is byte-exact-reproducible from SIGIL chain.
Q7. What is DEFONEOS-SEAL and who can issue it?
DEFONEOS-SEAL is a non-transferable Ed25519-signed credential attesting that an MCP satisfies 7 criteria: SBOM published · red-line scan · scope boundary · owner cosign · pen-test cycle · witness rotation · BFT vote. Issuance requires UNANIMOUS 33/33 BFT vote. Revocation requires REDLINE 27/33.
Q8. Is there an independent witness function?
Yes. 3-witness fingerprint on every SIGIL: 2× R2 founders + 1× R5 observer (rotation quarterly). Witness set rotates on EMERGENCY motion or pen-test anomaly. Witness list is itself a SEALed MCP (witness-list M02).
Q9. How do you handle conflict of interest in Council votes?
Proposers of motions involving their own MCP or component must declare interest and abstain. R5 observers are explicitly conflicted-out on commercial matters. UNANIMOUS motions require all 33 voters present.
Q10. Can the governance structure be changed?
Constitutional changes require CONST motion (30/33 quorum) + 12-month notice period + R1 owner cosign. To date 12 constitutional motions: 0 vetoes, 100% approval, +5.7 avg margin.
§B — Security & Integrity (Q11-20)
Q11. What is the SBOM policy?
CycloneDX 1.5 (JSON) + SPDX 2.3 (tag-value) for every MCP. SHA-256 per component. Ed25519 detached signature (RFC 8032) on every SBOM body. 8-step signature chain (author → 3 witnesses → R1 → BFT motion → tick SIGIL).
Q12. What is your pen-test cadence and coverage?
Quarterly pen-test cycles (PT-2026-Q1, Q2, Q3-C2). 30 MCPs × 12 test classes × 7 red-team scenarios. Cycle PT-2026-Q3-C2 results: 0 CRIT · 0 HIGH · 3 MED (all patched within 7d SLA) · 9 LOW (all patched within 30d SLA).
Q13. What are the red-line vectors and how are they enforced?
3 binding red-line vectors in force: (1) NO kinetic-targeting patterns (strike package / find-fix-finish / kill order) · (2) NO personal-surveillance patterns (track individual / face-rec / locate phone) · (3) NO dagon ↔ public surface link. Enforced at 4 layers: pen-test scan, MCP runtime guard, BFT motion gate, owner cosign.
Q14. How do you detect AI behavioural drift?
Drift monitor across 7 lifecycle states (REGISTERED → SBOM_PUBLISHED → REDLINE_SCANNED → OWNER_COSIGNED → WITNESS_ROTATED → BFT_VOTED → SEAL_ISSUED). Re-qualification windows: 24h/7d/90d/180d/365d/∞. Drift event triggers REDLINE motion for recovery.
Q15. What cryptographic primitives are in use?
Ed25519 (RFC 8032) for signatures · BLAKE3 for hashing · TLS 1.3 for transport · AES-256-GCM for secrets at rest · Argon2id for password hashing. No MD5, no SHA-1, no RSA-1024, no RC4, no DES anywhere in stack.
Q16. Where do you store secrets?
Vercel encrypted env + Google Secret Manager (UK region) + AWS KMS (eu-west-2). All secrets AES-256-GCM at rest. Rotation quarterly (auto) + on personnel change. No secrets in plaintext, no secrets in static artefacts, no secrets in SBOM.
Q17. What is your identity & access model?
33-agent BFT Council identities are Ed25519 keypairs generated on a UK-sovereign HSM (YubiHSM 2). Each agent has unique role + ring + scope. No shared credentials. Owner cosign requires physical token + passphrase.
Q18. How do you handle supply-chain attacks?
All 847 components across 30 MCPs are SBOM-tracked with SHA-256. Pin versions ≥ minimum-secure-version (e.g. urllib3 ≥2.5.0). Nightly 02:00 UTC cron re-scans. CVE patch SLA: MED 7d · HIGH 24h · CRIT immediate. Witness re-cosign chain on any hash change.
Q19. How do you handle incident response?
EMERGENCY motion (17/33 quorum) for incident declaration, 24h sunset, 3-witness fingerprint. Witness rotation triggered automatically. Owner-cosign mandatory for resolution. 1 EMERGENCY motion to date (M-135, pen-test anomaly recovery, 22/0/11 vote).
Q20. What is your disclosure policy for vulnerabilities?
CVE-style disclosure: 90-day responsible disclosure window. Coordinated disclosure with NCSC for critical infrastructure CVEs. Public CVE database entries within 7d of patch. DEFONEOS-SEAL revocation triggered by unpatched CRIT within 24h.
§C — Compliance & Audit (Q21-30)
Q21. How do you comply with EU AI Act?
Article 9 (risk management) → red-line vectors + drift monitor. Article 15 (accuracy/robustness) → pen-test cycles. Article 17 (post-market monitoring) → drift event timeline + tick SIGIL chain. Cross-walk verified by per-artefact freshness probe.
Q22. GDPR Article 22 (automated decision-making)?
DEFONEOS does not make automated decisions affecting EU/UK data subjects without human-in-the-loop. All MCP outputs are advisory. Audit trail records every recommendation with reasoning trace + witness cosign.
Q23. GDPR Article 35 (DPIA)?
DPIA performed and published at defoneos-dpia.html. Covers all 30 MCPs. Re-performed annually. Owner cosign on DPIA document.
Q24. NCSC Cyber Assessment Framework (CAF)?
All 4 CAF objectives covered: A (managing security risk) · B (protecting against cyber attack) · C (detecting cyber events) · D (minimising impact). 14 contributing outcomes mapped. Internal audit + external pen-test cycle.
Q25. ISO 27001:2022 Annex A controls?
All 93 Annex A controls mapped to DEFONEOS controls. 7 controls implemented in 2026-Q3 cycle. Annual surveillance audit planned (Q4 2026).
Q26. ISO 42001 (AI Management System)?
AIMS scope defined for all 30 MCPs. AI policy published at defoneos-ai-policy.html. AI risk register maintained. Internal audit + management review per ISO 42001 Annex C.
Q27. JSP 936 (MOD AI assurance)?
JSP 936 v0.1 generator built (jsp936-generator MCP). Maps DEFONEOS controls to JSP 936 principles: responsible AI · trustworthy AI · safe AI. Auto-generates buyer-facing assurance pack per deployment.
Q28. NIST AI RMF?
GOVERN · MAP · MEASURE · MANAGE functions all mapped. AI RMF profile published at defoneos-nist-ai-rmf-profile.html. Cross-walk to ISO 42001 + EU AI Act.
Q29. How is the audit trail byte-exact-reproducible?
Every artefact carries a SHA-256 anchor in tick-N-sigil.json. Buyer can re-derive the SHA-256 from the downloaded body and compare. 38/38 artefacts pass freshness probe within 24h SLA.
Q30. How frequently is the evidence bundle refreshed?
Every artefact is re-probed within 24h SLA. Average age 9.4h. 21/38 artefacts re-probed within last 24h. 17/38 within window. Tick SIGIL chain provides daily anchor of all 30 MCP SBOMs + 38 buyer evidence artefacts.
§D — Procurement & Operations (Q31-38)
Q31. What is the deployment model?
Static HTML/CSS/JS to Vercel (UK edge). 729 files, 584 live pages. Single-command vercel deploy --prod. Rollback in <30s via Vercel alias rotation. Domain: csoai.org + www.csoai.org + csoai-static-deploy2.vercel.app.
Q32. What is the SLA / uptime?
