Reference tools for trustworthy agentic AI.

The artefacts below are designed to be used, not just read. The Board Briefing is the executive entry point. The Agentic AI Capability Stack™ is the canonical reference. The CDO Mandate translates the architecture into an organisational design. The library grows as each new artefact in the series is published.

Board Briefing

Agentic AI Liability and the Executive Mandate. Version 1.0. 21 May 2026. 2 pages.

The shortest path into the architecture, written for boards and C-suite. Frames agentic AI as a Halterhaftung problem (the organisation is strictly liable for what its agents do, independent of how the underlying model reasoned), explains why the traditional three lines of defence break at machine speed, and provides the five questions boards must put to the executive team today. Use this as the conversation opener with audit committees, risk committees, and chairs evaluating AI exposure. → Download PDF

The Agentic AI Capability Stack™

A Framework for Trustworthy Agentic AI. Version 3.0. 21 May 2026. 3 pages.

The canonical eleven-layer reference for the capabilities required to deploy autonomous agents under enforceable governance. Each layer is named to a W3C open standard. Each is mapped to an accountable role. Two structural gates (Ingestion and Deployment) sit between four zones of authority, with one grammar: the role accountable for the source attests; the role accountable for the destination approves. The framework inherits its structural pattern from the IO Capability Stack developed by Tony Edwards at bp (2006) and extended by the Norwegian IO Centre with five operators from 2010 to 2014. Mesh structure surfaced by JeanPaul Goldschmidt's pre-publication review. → Download PDF

The CDO Office: Mandate, Organisation, and Operating Modes

Version 1.0. 21 May 2026. 3 pages.

Translates the Capability Stack into an executive mandate. Names the four functions the CDO owns (ontology, knowledge graph, SHACL constraints, PROV-O provenance) by direct structural parallel with the CFO's chart of accounts, general ledger, internal controls, and audit trail. Specifies the reporting line (CEO), the counterpart role of Process Owner, the gate grammar, the six capability groups required inside the office, and three deployment modes that scale with the scope of autonomous operation. → Download PDF
