Architectural Layers & Protocols

Agent Action Telemetry Ingest (Low-Latency Kernel / Wasm Runtime Hook): Capturing every tool invocation, API request, file modification, and external message generated by an agent.
Cryptographic Hash-Chaining (Sequential SHAKE-256 & ML-DSA State Trees): Chaining action receipts into an immutable chronological ledger where modifying past actions invalidates all subsequent proofs.
Real-Time Governance & Alignment (Policy-as-Code / OPA Agent Policy Engine): Evaluating proposed agent actions against constitutional AI rules before permitting physical execution.
Quantum-Resilient Long-Term Audit (FIPS 205 SLH-DSA Notarized WORM Archives): Preserving legal and regulatory accountability records for autonomous systems across multi-decade lifespans.

Key Metrics: < 100 µs (Telemetry Logging Latency) | 100% (Action Traceability) | Immutable (Hash-Chained Audit Ledger) | EU AI Act (Regulatory Alignment Ready)
