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.

Third-Party Services & Dependencies

HEOSSI solutions integrate with and depend on third-party services including blockchain networks, cloud infrastructure providers, cryptographic libraries, identity providers, and certificate authorities.

HEOSSI is not responsible for:

  • Availability, performance, or security of third-party services
  • Changes to third-party APIs, protocols, or standards
  • Third-party service outages, breaches, or failures
  • Costs associated with third-party services
  • Compliance of third-party services with applicable laws

Performance metrics and capabilities may be affected by third-party service limitations. Customers are responsible for evaluating and accepting risks associated with third-party dependencies.

Deployment

XIIS deploys where others cannot

Sovereign, air-gapped, hybrid, and cloud-native deployment patterns are first-class concerns in the XIIS architecture - not afterthoughts.

Sovereign / Air-Gapped

Full XIIS stack deployable in disconnected environments. No external dependencies at runtime. Designed for defense, critical infrastructure, and classified operations.

Hybrid Cloud

Control plane on-premises or in a sovereign cloud. Data plane spans cloud and edge. Policy and telemetry flow through a unified fabric regardless of where compute runs.

Cloud-Native

Full deployment on AWS, Azure, GCP, or sovereign cloud providers. Kubernetes-native with OpenTelemetry instrumentation, health endpoints, and fleet-wide observability.

Edge / Industrial

Lightweight XIIS runtime for edge nodes, industrial controllers, and autonomous fleets. Supports 30+ hour autonomous operation cycles with human oversight checkpoints.

Multi-Tenant SaaS

Isolated tenant boundaries with shared platform services. Policy-aware identity mesh propagates trust and permissions across tenant domains without cross-contamination.

On-Chain / Hybrid Web3

XIIS control plane integrates with 24+ blockchain networks via WAHH and QSIG. Cryptographic identity and settlement fabric with PQC-aware attestation layers.

Production Readiness

Release validation is part of the platform

XIIS does not rely only on package-local tests. Production readiness includes build, smoke, end-to-end, and release-verification gates that validate deployability and assurance posture.

  • Repository-wide build, lint, typecheck, and unit coverage
  • 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

Solution Consumption Surface

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.
