XIIS: the architecture behind
trusted intelligence infrastructure
HEOSSI engineers secure, autonomous, and governable systems for high-consequence environments. XIIS is HEOSSI's internal governed substrate solution within that stack, standardizing cognition, execution, trust, control, assurance, and interoperability.
Built for regulated, adversarial, sovereign, industrial, and mission-grade environments.
What XIIS Is
The eXtended Intelligence Infrastructure System
XIIS is HEOSSI's internal intelligence substrate solution: a live governed control plane and runtime foundation that standardizes cognition, execution, trust, assurance, interoperability and operator visibility across the portfolio.
BEE - The Progressive Quantum-Native Intelligence Engine - and QNSI - Quantum-Native Security Infrastructure - are the two currently available HEOSSI solutions on XIIS. Other solutions remain staged across alpha, development, staging, or research and will be introduced by HEOSSI only as their readiness is established.
XIIS expands through four horizontal packs - revenue, enterprise operations, technology, and research - plus seventeen industry and critical-infrastructure packs spanning satellite, defense, biotech, healthcare, agriculture, energy, nuclear, quantum, financial services, government and public sector, telecom and communications, transportation systems, marine, manufacturing, chemical and materials, water and wastewater, and emergency services.

XIIS Core
Six layers. One governed substrate.
XIIS is organized into shared foundation, control and trust, cognitive substrate, execution substrate, assurance and observability, and the solution-consumption surface. The design target is bounded autonomy under audit.
Layer 01
Shared Foundation
Common contracts, durable persistence, and shared patterns that make the rest of XIIS composable.
- Shared contracts and schemas
- Persistence patterns and storage adapters
- Durable state handling
- Cross-platform package boundaries
Layer 02
Control and Trust
Governance, risk, identity, security, and QNSI-backed trust posture for bounded autonomy under audit.
- Identity and policy controls
- Governance and approval paths
- Risk scoring and release controls
- QNSI-backed trust and verification
- Security boundaries and runtime protection
Layer 03
Cognitive Substrate
Memory, context, knowledge, reasoning, and simulation systems that give XIIS bounded intelligence.
- Long-term memory and retrieval
- Context fusion and state modeling
- Knowledge systems
- Reasoning and confidence scoring
- Simulation and rehearsal
Layer 04
Execution Substrate
Inference, workflows, orchestration, tools, agents, and data fabric that turn intelligence into controlled action.
- Inference and model routing
- Workflow checkpoints and orchestration
- Agent and tool execution
- Data fabric and execution traces
- Replayable runtime behavior
Layer 05
Assurance and Observability
Telemetry, evaluation, grading, replay, and release validation to keep autonomous behavior measurable and auditable.
- Observability and runtime telemetry
- Evaluation and trace grading
- Failure analysis and replay
- Release validation gates
- Production-readiness assurance
Layer 06
Solution Consumption Surface
The SDK, MCP server/runtime, and domain packs that expose XIIS to the rest of the HEOSSI portfolio.
- Node SDK consumption
- MCP server and remote tool execution
- Cross-solution interoperability
- Domain-pack consumption model
Engineering Doctrine
The four principles that run through every layer
NIST-finalized quantum-safe primitives anchor every layer
ML-KEM-768/1024 key exchanges, ML-DSA/SLH-DSA signatures, and hybrid crypto pipelines secure control planes, data planes, and device identities. OpenSSL 3.5+ integration with FIPS 203/204/205 compliance and HQC backup algorithm support.
Agent-native runtime with MCP and A2A protocols
AI agents run as first-class citizens via semantic IPC, Model Context Protocol (MCP) for context access, Agent2Agent (A2A) for multi-agent coordination, and authenticated capability tokens. Governed automation with 30+ hour autonomous operation capability.
Zero-trust connectivity with quantum-resistant overlay
Sovereign mesh networking with PQC-secured tunnels, programmable enclaves, and policy-aware gateways. SASE integration with continuous verification, real-time posture assessment, and sub-5s incident response across clouds, industrial estates, and on-chain systems.
Deterministic governance with immutable telemetry
Every workflow emits Merkle-anchored audit artifacts, policy decisions with cryptographic attestation, and recovery hooks. OpenTelemetry instrumentation provides fleet-wide observability and evidence-grade audit trails for regulated teams. HEOSSI's planned assurance programme covers ISO/IEC 27001:2022, ISO/IEC 42001:2023, and evaluation of applicable cryptographic modules against ISO/IEC 19790:2025. Tentative timing is Q4 2026 or Q1 2027, subject to funding. No certification or validation is currently represented as complete.
Current Platform Surface
What XIIS includes now
XIIS is already a governed runtime, not a speculative label. These are active platform surfaces shaping how HEOSSI systems learn, operate, and release.
Trust Stack
How trust is enforced across XIIS
The Trust Stack is the trust and governance model that runs across the XIIS architecture. It is not the whole architecture - it is the enforcement model inside it. Four layers, each hardening the one above.
Observability
Runtime telemetry, agent monitoring, cost tracking, reliability analytics
Security & Privacy
Threat detection, abuse detection, trust boundaries, HMAC verification
Risk & Assurance
Risk scoring, guardrails, evidence gates, audit trails, rollback, kill switches
Governance
Policy engine, approval gates, change control, compliance rules
Identity & Access
Identity graph, roles, delegation, secrets, access policies
Trust enforced bottom-up: Identity → Governance → Risk → Security → Observability
Layer 4
Autonomous Control & Coordinated Decision-Making
Autonomous orchestration steering mission-critical systems with coordinated intelligence and runtime policy enforcement.
Layer 3
Cryptographic Security, Key Fabric, Runtime Integrity
Quantum-safe cryptography, key orchestration, and runtime integrity hardening to withstand adversarial pressure.
Layer 2
Distributed Identity & Policy Fabric
Policy-aware identity mesh propagating trust, permissions, and telemetry across sovereign and enterprise domains.
Layer 1
Verifiable Compute & Data Provenance
Deterministic compute, data lineage, and verifiable reasoning anchoring every system action in cryptographic proof.

- Dependency verification, audit checks, and tracked-secret scanning before push
- Smoke validation for SDK, MCP, and control-plane health
- End-to-end auditable rehearsal with failure injection
- Release-gate readiness, attestation-chain validation, and assurance reporting

How solutions consume XIIS
Solutions use XIIS in-process through the SDK and cross-process through the XIIS MCP server surface. That keeps governed capabilities reusable without exposing private implementation details.
