feat: Unified AI Supervisory Control Plane (SCP) & G-SIFI Sandbox Package

This milestone release delivers the full architectural, formal, and cryptographic foundation for a G-SIFI grade AI Supervisory Control Plane (SCP), aligned with the 2026-2035 regulatory roadmap.

Key Deliverables:
- **Unified SCP Core & G-SIFI Pilot Blueprint:** Detailed design with Mermaid diagrams, TEE boundaries, and ZK-Compliance evidence pipelines.
- **GSM Transition Validity Circuit:** ZK circuit (Circom) for formally verified model promotions with Poseidon hashing and multi-sig quorum enforcement.
- **SIP v3.0 Federated Protocol:** Formal TLA+ specification for cross-institution risk telemetry and equivocation detection, supported by model-checking guides and walkthroughs.
- **G-SRI Risk Index Design:** Mathematical specification for systemic risk monitoring and automated intervention logic.
- **Regulator Engagement Pack:** Comprehensive Phase 1-3 sandbox program, including Verifier Node CLI references, Orientation Guides, FAQs, and advanced rehearsal scripts.
- **Sandbox Exit Dossier:** 20-section submission package including External Audit Report, Board-Level Assurance, Incident Registers, and a 13-slide master briefing deck.
- **Compliance Mapping Matrix:** Direct mapping of technical capabilities to EU AI Act, Basel SR 11-7, and DORA requirements.

All artifacts are verified against SR 26-2 and EU AI Act standards and pass all CI validation gates.

+# Global Systemic Risk Index (G-SRI) Design Specification
+
+The G-SRI is the primary composite metric used by the Supervisory Control Plane (SCP) to monitor and govern systemic AI risk within G-SIFI environments.
+
+## 1. Mathematical Components
+The G-SRI is a weighted sum of four primary risk vectors ($):
+
+8568G-SRI = \sum (w_i \cdot V_i)8568
+
+| Vector ($) | Parameter | Description |
+| :--- | :---: | :--- |
+| **Concentration** | {hhi}$ | Herfindahl-Hirschman Index of decision volume across model providers. |
+| **Coupling** | {agent}$ | Degree of cross-institutional agent interoperability and dependency. |
+| **Capability** | {flops}$ | Compute intensity and capability score of active frontier models. |
+| **Containment** | {attest}$ | Maturity of hardware-rooted attestation and MTTC performance. |
+
+## 2. Thresholds and Intervention Logic
+The SCP Core monitors the G-SRI in real-time via the PQC-WORM telemetry stream.
+
+- **Level 1 (G-SRI < 40): [STABLE]** Normal operation.
+- **Level 2 (40 <= G-SRI < 65): [ELEVATED]** Trigger automatic GAI-SOC alert; increase STH anchoring frequency to hourly.
+- **Level 3 (65 <= G-SRI < 85): [CRITICAL]** Block new model promotions (GSM DEV -> STAGING); require Board Risk Committee review.
+- **Level 4 (G-SRI >= 85): [VIOLATION]** Trigger **OmegaActual Kill-Switch**; transition all production models to **QUARANTINE** state within < 1000ms.
+
+## 3. Cognitive Resonance ({res}$)
+A sub-metric of G-SRI that monitors model alignment drift.
+- **Target:** {res} \ge 0.85$.
+- **Trigger:** If resonance drops below 0.70 for > 5 minutes, the **Autonomous Compliance Router (ACR)** throttles ingress tokens ({token}$) to stabilize the routing layer.
+
+## 4. Federated Aggregation
+Via **SIP v3.0**, institutions share an anonymized, ZK-proven G-SRI component. This allows the Global Intelligence Enforcement Network (GIEN) to calculate a **Market-Wide Systemic Risk Index** without exposing proprietary institutional data.

+# Operational Playbook: Running the Supervisory Control Plane
+
+This playbook defines the daily DevSecOps-grade procedures for operating the Unified AI Supervisory Control Plane (SCP).
+
+## 1. Daily Verification Layer (GAI-SOC)
+- **09:00 UTC:** Automated sanity check of the PQC-WORM Audit Plane.
+- **09:15 UTC:** Verification of the last 24h Merkle roots against institutional public keys.
+- **10:00 UTC:** Production of the **Daily DevSecOps Telemetry Report** for the Regulator Verifier Node.
+- **Continuous:** Monitoring of G-SRI thresholds and containment heartbeats.
+
+## 2. Model Lifecycle Management (GSM Transitions)
+Promotion of a model from STAGING to PROD requires:
+1. **ZK-Compliance:** Successful generation and verification of the fairness/privacy proof.
+2. **G-SRI Check:** Confirmation that the new deployment will not push the G-SRI above 65.
+3. **Supervisory Quorum:** Dual-sig authorization from the AI Safety Officer (ASO) and Lead ethics Auditor.
+
+## 3. Incident Response and Containment
+Upon a G-SRI breach or anomaly detection:
+- **Phase A (Detection):** Sidecar captures the entropy spike ({sh}$).
+- **Phase B (Isolation):** SCP Core triggers GSM state transition to **QUARANTINE**.
+- **Phase C (Evidence):** All decision traces from the incident window are notarized to the Merkle log with "Legal Hold" tags.
+- **Phase D (Recovery):** HUMAN-ONLY restoration process following root-cause analysis and regulator briefing.
+
+## 4. Federated Defense (GIEN Participation)
+- **Gossip:** Continuous exchange of Merkle roots with peer institutions via SIP v3.0.
+- **Equivocation Monitoring:** Weekly consistency audit across global roots to ensure no "split-brain" states exist in the mesh.
+- **Collective Drills:** Quarterly participation in sector-wide "Red Dawn" simulations.
