Invariant enforcement
Study deterministic mechanisms that evaluate and enforce structural constraints as a system executes.

Structural safety during execution.
DUJ investigates how multi-agent AI systems can be kept within defined structural limits while they operate.
Technical definition:DUJ is a deterministic runtime governance substrate for multi-agent systems, designed to enforce structural safety invariants during execution rather than merely measure unsafe behavior after the fact.
Our purpose
Researching systems that remain structurally bounded as they evolve.
In practical terms, we are investigating whether complex groups of AI agents can be prevented from drifting outside predefined operating constraints.
The DUJ-FEITH Foundation is an independent research and stewardship organization advancing public-interest work on multi-agent coordination, invariant-based stability and runtime governance. Its central research question is whether complex agent systems can preserve defined structural conditions throughout execution—even as interactions, authority and internal state change over time.
Scientific status
An active research programme—not a finished safety claim.
DUJ is an experimental research framework. Its underlying mechanisms have produced promising results in controlled simulations, but they have not yet been independently validated or demonstrated in deployed multi-agent systems.
The next phase extends validation toward embodied, vision-to-action and heterogeneous multi-agent settings.
Evidence before claims
The Foundation publishes selected technical work, validation artifacts and limitations where disclosure is compatible with responsible stewardship. Results obtained in simulation do not, by themselves, establish general safety in open-world systems.
Research programme
From post-hoc evaluation to enforceable structure.
Multi-agent stability
Investigate how authority, state and coordination can remain bounded across changing agent relationships.
Reproducible evidence
Develop simulations, ablations and edge-based validation harnesses that expose both performance and failure boundaries.
Stewardship
Public-interest research with a clear institutional boundary.
The DUJ-FEITH Foundation stewards the public-interest research programme, including its theoretical framework, validation agenda and selected research publications.
DUJ-FEITH Labs inc. is a separate commercial vehicle intended for future implementation, tooling and deployment activity. Research claims and commercial development remain subject to the same evidence-first standard.

Isabelle Thivierge · Founder and Research Director
The DUJ-FEITH Foundation was founded and is independently led by Isabelle Thivierge, a Toronto-based researcher whose background spans strategic partnerships, business development and applied AI research. Her work focuses on deterministic runtime governance for multi-agent systems.
The Foundation was federally incorporated in Canada in 2025 as a not-for-profit organization. Technical documentation and ongoing work are available on GitHub.
