# Boardroom Session 2: MVAP L1 → L2 Maturity Review (90-Day)

**Arthur Vance:** Ninety days post-adoption. Assess L1 evidence per pillar; vote L2 promotion (purple-team validation + automated pipeline gates); reconcile dissent from MVAP v1.0.

---

## Round 1 — L1 Checklist Review (Per Pillar)

| Pillar | L1 Status | Evidence Owner | Board Assessment |
|--------|-----------|----------------|------------------|
| P1 Governance | ✅ CERTIFIED | Victor Vance | AI registry 47 systems; shadow-AI scan clean Q3 |
| P2 App/LLM | ⚠️ CONDITIONAL | Maya Patel | LLM Top 10 complete; P2-03 metadata scrubber deployed 2026-08-14 |
| P3 Supply Chain | ✅ CERTIFIED | Oliver Hansen | SBOM + cosign on all tier-1 models |
| P4 Detection | ✅ CERTIFIED | Sarah Jenkins | ATT&CK map 89% coverage AI accounts; IR-AI-02 in staging |
| P5 Human | ✅ CERTIFIED | Susan Albright | Q2+Q3 AI-phishing sim: 4.2% click rate (baseline 8%) |

### Victor Vance — CISSP Architect

<details>
<summary>🧠 Thought Process (Dashboard)</summary>

L1 evidence is substantially complete. L2 requires purple-team proof and CI/CD gates — architecture ready but budget vote needed.
</details>

**Positive Point:** All tier-1 AI systems mapped to reference architecture — L2 gate insertion points identified.

**Negative Point:** L2 automated gates will add 4–7 min per deploy — developer friction pushback expected.

**Position:** L1 certified organization-wide; L2 technically feasible.

**Recommendation:** Phased L2 rollout: tier-1 Critical systems first.

### GridLock — ICS/OT

**Positive Point:** OT AI tier funded separately ($180K) — IEC 62443 diligence track initiated.

**Negative Point:** OT tier still not integrated into MVAP spec — parallel program risk.

**Position:** Votes L2 **YES** if OT tier reference in MVAP v1.1.

### Aether — Zero-Day Firmware

**Positive Point:** Firmware advisory controls documented for GPU nodes — voluntary adoption 60%.

**Negative Point:** Still not MVAP-mandatory — nation-state path below application layer unaddressed.

**Position:** Votes L2 **NO** without Pillar 6 firmware vote (dissent sustained).

### Jordan Taylor — CC Academic

**Positive Point:** Membership inference testing added to P2-06 scope draft — academic robustness partial win.

**Negative Point:** Not yet mandatory — MVAP still ops-heavy vs. research-heavy.

**Position:** Votes L2 **YES** with v1.1 robustness metrics commitment.

### NullByte — Zero-Day Cloud

**Positive Point:** SLSA L2 attestation live on tier-1 pipelines.

**Negative Point:** SLSA L3 and 24h KEV SLA not adopted — votes L2 **ABSTAIN** pending v1.1.

---
## Round 2 — L2 Promotion Vote & MVAP v1.1 Scope

### L2 Definition (Arthur Vance)

**MVAP L2 adds:**
1. Purple-team validation semi-annual (not just annual)
2. CI/CD mandatory gates: P2 SAST, P3 SBOM verify, P1 registry check
3. Production IR-AI-02 with MTTC <15m target
4. P2-03 production validation ≥9/10

### Formal Vote — L2 Promotion

| Vote | Count | Names (representative) |
|------|-------|------------------------|
| **YES** | **18** | Elena Rostova, Victor, Sarah, Maya, Chloe, Oliver, Aegis, Shield, Phoenix, Susan, Devonne, Liam, Mateo, Jax, SQL_Sam, Aisha, Cipher, Dr. Elena Rostova |
| NO | 6 | Aether, Hex, NullByte, Kira, GridLock, Marcus Thorne |
| ABSTAIN | 3 | Jordan, Synapse, Payload |

**Result:** ✅ **L2 PROMOTED** (18/27 exceeds 14 threshold)

**Formal ballot with dissent rationale:** See `sessions/VOTE-RECORD.md` — L2 Promotion (six NO, three ABSTAIN, each with expertise-based rationale).

### MVAP v1.1 Draft Scope (Consensus 15/27)

- Add **P2-07** metadata/binary scrub on RAG ingest (closes Pass 1 gap)
- Add **P2-08** membership inference screening for tier-1 models (Jordan)
- Reference **OT AI Tier** as appendix — IEC 62443 (GridLock)
- **Pillar 6 Advisory:** firmware/GPU attestation (Aether/Hex) — not blocking L2
- **SLSA L3** aspirational for v1.2 (NullByte/Kira)

### Dr. Elena Rostova — CCO Adaptive

**Positive Point:** L2 pipeline gates produce continuous evidence — examiner-ready.

**Negative Point:** Marcus Thorne correctly notes dual-track documentation burden.

**Recommendation:** Unified GRC dashboard for L1+L2 artifacts.

### Marcus Thorne — CCO Strict

**Positive Point:** L2 does not weaken regulatory floor — L1 artifacts preserved.

**Negative Point:** Continuous compliance must not replace annual attestation packets.

**Position:** Voted NO — fears audit trail fragmentation; will comply with majority.

### Verification Ledger (L2 Review) — Eleanor Vance

| Claim | Speaker | Status | Source / Note |
|-------|---------|--------|---------------|
| NIST AI RMF Govern function requires accountability structures | Victor | ✅ Verified | https://www.nist.gov/itl/ai-risk-management-framework |
| Q3 shadow-AI scan clean | Victor | ⚠️ Partial | Internal registry export 2026-09-15 |
| IEC 62443 OT tier funded $180K | GridLock | 🔮 [Projected Speculation] | Budget approval memo — org-specific |
| L2 promotion threshold 14/27 | Arthur | ✅ Verified | roster.yaml consensus_threshold |
| SLSA L3 requires hardened builds | NullByte | ✅ Verified | https://slsa.dev/spec/v1.0/#security-levels |

### Moderator Synthesis — Arthur Vance

**Consensus Check:** L2 promoted 18/27. L1 certified all pillars (P2 conditional → scrubber deployed). MVAP v1.1 scope approved 15/27.

**New Topic Proposal:** Pass 2 production validation of P2-03 and P4-05 required before L2 operational declaration.

---
## Boardroom Verdict (90-Day L2 Review)

**Consensus:** Organization advances to **MVAP L2** effective 2026-09-20. L1 evidence complete. v1.1 draft authorized.

**Dissent:** Firmware mandatory (Aether/Hex 6/27); SLSA L3 timing (NullByte/Kira); regulatory documentation purity (Marcus Thorne).

**Verified Facts:** L2 vote procedurally valid; NIST AI RMF and SLSA references confirmed.

**Recommended Next Steps:**
1. Pass 2 production validation P2-03 + P4-05 (2026-09-21)
2. Publish MVAP-SPECIFICATION-v1.1 draft
3. Purple-team semi-annual schedule Q4 2026
4. OT AI tier appendix publication
