System architecture and integration guides
Technical documentation for Project HGE and institutional evidence infrastructure. Documentation covers system architecture, experiment specifications, validation workflows, and integration patterns.
Project HGE documentation
Project HGE (Hypothesis Generation Engine) represents Northflow's automated scientific discovery infrastructure. The system operationalizes the scientific method through hypothesis-driven experimentation, executing on real instruments including remote quantum hardware used as a demanding validation environment. HGE provides instrument-grade validation workflows, uncertainty-aware reasoning, and comprehensive provenance tracking across experimental cycles.
This documentation covers the system architecture, experiment specification schemas, result data structures, and integration patterns for connecting instrument backends. The methodology emphasizes rigorous validation, drift detection, and evidence-based confidence updates throughout the discovery process.
Integration guidance addresses instrument backend interfaces, data flow patterns, and validation workflows that enable HGE to coordinate experiments across diverse physical systems while maintaining provenance and uncertainty quantification.

Documentation scope
Structured documentation enables institutional oversight, audit readiness, and long-term operational continuity.
Northflow Technologies maintains comprehensive documentation covering system architecture, operational procedures, governance frameworks, and compliance methodologies.
Documentation is organised into tiers based on institutional requirements and engagement level:
Public institutional materials
Framework overviews, validation summaries, and general system descriptions.
Structured engagement
Technical specifications, implementation guides, and operational procedures provided through structured engagement.
Controlled disclosure
Detailed architectural documentation and security specifications subject to qualification requirements.
Documentation lifecycle
Documentation follows a structured lifecycle ensuring accuracy, currency, and institutional transparency:
Documentation lifecycle: Design → Validate → Maintain → Govern (continuous improvement applied across all stages)
Development and validation
Documentation is developed in parallel with system design and validated through internal review processes.
Version control and change management
All documentation is subject to version control with clear change tracking and audit trail maintenance.
Distribution and access control
Documentation distribution follows access control protocols aligned with institutional engagement requirements.
Maintenance and updates
Regular review cycles ensure documentation remains current with system evolution and regulatory developments.
Access model
Documentation access is provided through structured engagement pathways appropriate to institutional requirements:
Access qualification criteria
- Institutional affiliation with government entities, regulatory authorities, or critical infrastructure operators
- Defined use case or procurement evaluation requirement
- Appropriate confidentiality and data handling protocols
- Formal engagement request through institutional channels
