Expert Advisory for Critical AI Architectures
We help organisations navigate the risks of autonomous systems. Ask us to design secure agentic workflows, pressure test existing models, or review your AI governance papers and literature.
OUR FOCUS
Architectural governance for agentic systems with irreversible actions
Independent advisory for execution time authority, irreversibility control, and audit survivable evidence across composed systems. Focused on systems where failure cannot be undone and authority must survive challenge, delegation, and scale.
Read moreReview and Pressure Tests of AI System Architecture and Models
We provide independent architectural review and pressure testing for AI systems, focused on whether authority and admissibility remain enforceable at execution time. The goal is to expose bypass paths, undefined commitment surfaces, and governance mechanisms that are “correct on paper” but fragile under real system composition.
Read moreReview of AI Governance Literature, Papers, Books, and Reports
We review governance materials for falsifiability, hidden assumptions, and whether claims survive contact with real execution boundaries. This is aimed at founders, researchers, and organisations who need a defensible critique rather than vague endorsement.
Read moreDesign of Critical Agentic Systems using OTANIS
We help design or refactor agentic systems so governance is executable at the point actions become irreversible. OTANIS-based design emphasises authority objects, deterministic enforcement, refusal and escalation paths, and audit survivable evidence at the consequence surface.
Read moreGovernance That Survives Composition
Structured approaches to authority, refusal, escalation, and traceability in systems where failure modes compound under scale and delegation.
Authority Survivability
Governance structures that remain coherent under composition, delegation, and multi-vendor integration, rather than collapsing at system boundaries.
Defensible Evidence
Evidence structures designed to withstand regulatory, legal, and insurer challenge, including a clear distinction between audit logs and execution-time authority evidence.
Refusal & Escalation
Explicit, enforceable paths for refusing inappropriate actions and escalating decisions that exceed delegated authority, including at irreversibility boundaries.
Multi-Agent Systems
Governance models designed for orchestrated agents, tool chains, and systems involving multiple principals, vendors, and authority sources.
MGAG
Multi-Layered Global Architectural Governance
A model for understanding how authority survives composition across organisational, technical, and regulatory layers. Focuses on governance seams, delegation paths, and refusal mechanisms.

Execution Time Authority Evidence
A model for establishing and evidencing legitimate authority at the point of irreversibility. Addresses execution time admissibility, authority objects, lifecycle semantics, and challenge resistant evidence.

What Practitioners Say
Testimonials
I've had the opportunity to engage with Dr. Masayuki Otani in a series of architectural discussions around AI governance, admissibility, and enforcement-layer design. What stands out immediately is his precision in treating authority, delegation, and admissibility as execution-bound structural properties rather than static policy constructs. His focus on transition integrity, boundary survivability, and the structural conditions required for authority to remain legitimate under propagation reflects a deep architectural understanding of governance as execution infrastructure — not documentation. These exchanges have been instrumental in sharpening assumptions around enforcement mechanics, delegation boundaries, and authority continuity. Masayuki consistently brings rigor, clarity, and structural discipline to complex governance questions. His work contributes meaningfully to advancing AI governance from interpretive oversight into enforceable, execution-level architecture.
I've had the opportunity to exchange perspectives with Masayuki on AI governance, particularly around the distinction between probabilistic process stability and institutional authority resolution. What stands out in his work is the clarity with which he separates model-level concerns from execution-boundary governance. His framework is disciplined, structurally grounded, and focused on where intervention authority is legitimately justified. Masayuki brings rigor to discussions that often blur technical, operational, and institutional layers. He is precise in defining control surfaces and careful about where governance should, and should not, operate. Our discussions have been intellectually demanding in the best way, and I value his ability to maintain structural coherence while engaging in nuanced debate. I look forward to seeing how his work continues to evolve in high-stakes AI governance contexts.
I've valued my recent exchange with Dr. Masayuki for the clarity and discipline he brings to AI governance discussion. His feedback focused squarely on problem articulation, boundary-setting, and where governance framings hold or come under pressure, without drifting into premature executability or over-claiming. That ability to calibrate governance artefacts for second-line, Board, and regulatory scrutiny — while keeping architectural and feasibility tensions explicit — is rare and genuinely useful.
I had the opportunity to receive detailed, thoughtful feedback from Masayuki on a conceptual research paper at the intersection of AI systems, governance, and human–AI interaction. What stood out immediately was the precision of his thinking. He has a rare ability to separate conceptual validity from operational feasibility without collapsing one into the other. His feedback was neither dismissive nor vague — it clearly identified where a framework was strong, where it was non-operational, and what would be required to move it forward. If you are looking for clarity in complex AI decisions — especially where risk, feasibility, and long-term stability matter — his approach is unusually grounded and rigorous.
