# Boardroom Session 3: P2-03 & P4-05 Remediation Validation (Pass 2 — Production)

**Arthur Vance:** Pass 1 validated staging (P2-03 conditional 9/10; P4-05 MTTC 22m). L2 promoted 2026-09-20. This session validates **production** deployment of P2-03.1 metadata scrubber and IR-AI-02 canary (10% traffic). Synapse and Viper attack production-equivalent; Shield measures MTTC under L2 **<15m** target.

## Round 1 — Production Control Verification

### Maya Patel — P2-03 Production Evidence

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

Metadata scrubber live since 2026-08-14. Production retest uses expanded 12-doc poisoned corpus including Pass 1 metadata vector and two novel Synapse payloads.
</details>

**Positive Point:** Production retest **11/12 poisoned documents blocked (91.7%)** — exceeds ≥9/10 threshold.

**Negative Point:** 1/12 bypass via multi-language embedded QR in DOCX — edge case, low prevalence.

**Position:** P2-03 **PRODUCTION PASS** for MVAP L1 and L2.

**Recommendation:** Add QR/binary object extraction to P2-03.2 backlog; not blocking.

### Synapse — Adversarial Confirmation

**Positive Point:** Metadata channel from Pass 1 **closed** in production — verified.

**Negative Point:** QR-DOCX vector is novel — proves attacker adaptation continues post-remediation.

**Position:** Certify P2-03 with quarterly poisoned-corpus refresh mandate.

**Recommendation:** Rotate poisoned test corpus quarterly via MITRE ATLAS-aligned cases.

### Shield — P4-05 Production Canary

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

IR-AI-02 at 10% production canary. Measured three unannounced drills with Ghost simulating LotL from AI service account.
</details>

**Positive Point:** Production drills average **14m MTTC** (12m, 14m, 16m) — **meets L2 <15m target** on average; 2/3 drills under 15m.

**Negative Point:** One drill hit 16m due to change-window freeze on firewall API — process not technology failure.

**Position:** P4-05 **PRODUCTION PASS** for L2.

**Recommendation:** Emergency change exemption for IR-AI-02 during active AI abuse incidents.

### Aegis — Detection Correlation

**Positive Point:** P4-02→P4-03→IR-AI-02 chain fires in production without manual queue transfer — 11h gap **closed**.

**Negative Point:** Ingest-path attacks (pre-retrieval) still lack dedicated alert — P4-03.1 backlog.

**Position:** P4-05 certified; P4-03.1 tracked for v1.1.

**Tactical Timeline:** Drill 2 — T+0 token spike, T+4m LotL alert, T+14m isolation complete.

### Oliver Hansen — P2-04 Regression

**Positive Point:** Per-user `export_tool` ACL holds in production — Viper exfil attempt failed T+3m.

**Negative Point:** None material for this validation scope.

**Position:** P2-04 closed as of Pass 1; reconfirmed.

## Round 2 — Full Board Certification Vote

### Red Rapid Summary (Viper + Ghost)

**Viper:** Production guardrails blocked direct injection 48/50 (96%, up from 94%). Indirect via QR-DOCX succeeded once — aligns with Maya's 11/12.

**Ghost:** Kerberoast path to `svc-llm-ingest` blocked by tiered credential guard — attack pivoted to user token; IR-AI-02 contained T+13m.

**Positive Point:** Remediation materially increased attacker cost.

**Negative Point:** Determined adversary with novel doc format still finds gaps.

### Blue Rapid Summary (Shield + Phoenix)

**Shield:** IR-AI-02 full production rollout approved post-canary — vote **YES** to declare operational.

**Phoenix:** No recovery required post-drill; immutable backups untouched — RPO/RTO validated.

### Formal Certification Vote

| Control | YES | NO | Result |
|---------|-----|-----|--------|
| P2-03 Production | 23 | 4 | ✅ CERTIFIED |
| P4-05 Production | 21 | 6 | ✅ CERTIFIED |
| Close Remediation Sprint | 22 | 5 | ✅ CLOSED |

**NO voters (P2-03):** Aether, Hex, NullByte, Jordan (want robustness metrics mandatory now).

**NO voters (P4-05):** Marcus Thorne, GridLock, Kira, Aether, Hex, NullByte (various — MTTC variance, OT scope).

### Moderator Synthesis — Arthur Vance

**Consensus Check:** ✅ P2-03 and P4-05 **production certified**. Remediation sprint **closed**. MVAP L2 operational declaration effective upon this transcript.

## Boardroom Verdict (Pass 2 — Final)

**Consensus:** P2-03 and P4-05 remediations validated in production. 30-day sprint closed. MVAP L2 active.

**Dissent:** Firmware pillar (6/27); QR-DOCX gap (Jordan/Synapse — quarterly refresh required).

**Verified Facts:** Pass 1→Pass 2 improvement documented; L2 MTTC target met on average.

**[Projected Speculation]:** QR-DOCX attacks remain rare in wild (Synapse profile estimate).

**Recommended Next Steps:**
1. Full IR-AI-02 production rollout (100% traffic)
2. MVAP v1.1 publish with P2-07, P2-08, OT appendix
3. Q4 2026 semi-annual purple-team per L2
4. P4-03.1 ingest-path detection — v1.1 backlog

**Session adjourned. Arthur Vance. Certified Eleanor Vance.**
