+# Sentinel AI Governance Engineering Roadmap & Technical Plan (2026–2035)
+
+**Target Audience**: Senior Engineering Leadership, AI Safety Officers, Regulatory Auditors
+**Version**: 2.4.0 (Aligned with G-SIFI Roadmap)
+
+## 1. Feature Prioritization & UX Architecture
+High-density, expert-centric React 19 dashboard utilizing a "Cockpit" design pattern for high-frequency intervention.
+
+### Phase 1: Operational Foundation (Q3 2026)
+- **WORM Audit Logging**: Immutable append-only fabric using Kafka and S3 Object Lock.
+- **RBAC Enforcement**: Fine-grained access control via OPA/Rego sidecars.
+- **Hardware Attestation UI**: Real-time vTPM/TEE status indicators (PCR_MATCH=TRUE).
+- **Cognitive Attestation Gates**: Multi-step verification for high-risk model deployments.
+
+### Phase 2: Intelligence & Visualization (Q1 2027)
+- **AI-Driven Workflow Recommendation Engine**: Gemini-powered routing for optimal compliance workflows.
+- **Global Variable Map**: D3.js visualization of cross-agent dependencies and causal lineage.
+- **ComplianceDashboard v1**: Recharts-based telemetry for EU AI Act and NIST AI RMF.
+- **Web Speech API Integration**: Hands-free audit querying and voice-driven emergency overrides.
+
+### Phase 3: Assurance & Simulation (Q4 2027)
+- **EAIP Simulator Tooling**: Virtual sandbox for testing Agent Interoperability Protocol (EAIP) mesh stability.
+- **ZK-Proof Auditing (Groth16/SnarkJS)**: Generating privacy-preserving proofs for regulatory submission.
+- **PDF-Exported Reports**: Cryptographically signed evidence bundles (Annex IV / OSCAL).
+- **Global Variable Map Enhancements**: Real-time prompt injection detection and drift propagation mapping.
+
+### Phase 4: AGI/ASI Resilience (2028+)
+- **Global Kill-Switch Workflows**: "OmegaActual" decentralized multi-sig intervention protocols.
+- **Existential Risk Simulation**: Modeling catastrophic misalignment scenarios and mitigation effectiveness.
+- **Autonomous Compliance Router (ACR)**: Self-healing governance mesh for agentic systems.
+
+## 2. Compliance & Risk Monitoring (OSCAL Framework)
+Standardized mapping to global regulatory regimes using **OSCAL 1.1.2** for machine-readable compliance.
+- **EU AI Act**: High-risk system logging, risk management system (RMS) tracking.
+- **DORA / GDPR**: Resiliency monitoring and data sovereignty gates.
+- **NIST AI RMF / ISO 42001**: Mapping technical controls to organizational risk appetites.
+- **Export Capabilities**: Dynamic OSCAL/YAML generation for regulator-ready submissions.
+
+## 3. Cryptographic & Privacy Stack
+Implementing a multi-layered defense for audit integrity and institutional privacy.
+
+### PQC-WORM Audit Plane
+- **Integrity**: Audit events are hashed and signed using ML-DSA-65 (NIST FIPS 204) before being committed to an
+  S3 Object Lock bucket.
+- **Audit Traceability**: Hybrid signatures (ML-DSA + CRYSTALS-Dilithium) ensure long-term evidence durability
+  against post-quantum adversaries.
+- **Immutable Log Exports**: Cryptographically signed report exports (PDF/OSCAL) with embedded ML-DSA signatures.
+
+### Zero-Knowledge Compliance (zk-SNARKs & zk-STARKs)
+- **Groth16 Efficiency**: Primary ZK-circuit for real-time compliance attestations (e.g., verifying model
+  training data sanitization).
+- **Circom Toolchain**: Use SnarkJS/Circom for circuit design and proof generation in the browser/FastAPI sidecars.
+- **zk-STARK Migration**: High-throughput systemic risk reporting using zk-STARKs for trustless, transparent
+  scalability.
+
+### Confidential Computing & TEE Attestation
+- **Runtime Protection**: Sensitive governance logic (e.g., SARA alignment routing) executes within AMD SEV-SNP
+  or Intel TDX enclaves.
+- **Remote Attestation**: The Dashboard verifies the vTPM PCR (Platform Configuration Register) state of all
+  connected cockpit agents (PCR_MATCH=TRUE).
+- **Data Protection**: All telemetry and audit logs are encrypted using keys managed within the HSM-backed enclave.
+
+## 4. Policy Management & Formal Verification
+- **EAIP Policy Engine**: OPA (Rego) used for run-time permissioning and message filtering.
+- **TLA+ Specification Export**: Exporting operational policies to TLA+ for formal verification of safety properties.
+- **SARA (Self-correction Agent)**: Real-time alignment routing based on resonance metrics ($C_{res} \ge 0.85$).
+
+## 5. AGI/ASI Governance & Systemic Risk
+Ensuring alignment and containment for frontier models through multi-layered systemic risk controls.
+
+### AI Safety Council & Governance Roles
+- **Council Charter**: Define multi-sig approval chains for frontier model training and deployment ($> 10^{26}$ FLOPs).
+- **Digital Governance Roles**: AI Safety Officer (ASO), Lead Ethics Auditor, Systemic Risk Quant, and
+  Independent Third-Party Watchdog.
+- **Governance Enclaves**: Execution of high-impact decisions (e.g., model release) requires cryptographic
+  signatures generated within TEE enclaves.
+
+### Existential Risk Scenarios & Mitigations
+- **Emergent Autonomy Detection**: Real-time monitoring for non-sanctioned agent recursive self-improvement using
+  routing entropy ($H_{sh}$) and ingress token density ($H_{token}$).
+- **Misalignment & Reward Hacking**: Continuous resonance monitoring ($C_{res}$) against baseline constitutional
+  values; automated throttling if alignment drops below 0.85.
+- **Hardware-Rooted Kill-Switches**: Network-level containment and "OmegaActual" hardware kill-switches integrated
+  with AMD SEV-SNP/Intel TDX attestation.
+
+### Alignment & Stability Strategies
+- **StaR-MoE Stabilization**: SARA (Self-correction & Alignment Routing Agent) for real-time stabilization
+  of MoE routing layers.
+- **Constitutional Guardrails**: Immutable OPA/Rego policies governing cross-agent interactions and model outputs.
+- **Zero-Knowledge Systemic Risk Proofs**: Groth16-based ZK proofs for G-SRI reporting, enabling regulatory
+  oversight without institutional data leakage.
+- **International Frameworks**: SIP v3.0 telemetry sharing for collective defense within the Global
+  Intelligence Enforcement Network (GIEN).
+
+## 6. Technical Report Plan (Proposed Structure)
+A formal technical report to accompany the dashboard rollout for board-level and regulator review.
+1. **Executive Summary**: Vision for G-SIFI AI safety and governance maturity.
+2. **Architecture Deep-Dive**: React 19 Frontend, FastAPI Backend, and TEE/vTPM Execution Plane.
+3. **Assurance Methodology**: Formal verification (TLA+), ZK-proof generation, and WORM integrity analysis.
+4. **Regulatory Crosswalk**: Detailed mapping of technical controls to EU AI Act, DORA, and NIST.
+5. **Systemic Risk Evaluation**: Results from "Red Dawn" chaos engineering and drift simulation.
