In this extended 50-minute technical session, we explore why institutional regtech must move toward falsifiable lineage.

For bank CROs and Group Tax Directors, the challenge is no longer just the calculation—it is the provenance.

We break down the OrbaOS doctrine ("Admitted Before Calculated") and its application across two of the most complex regulatory regimes today: the Fundamental Review of the Trading Book (FRTB) and OECD Pillar Two (GloBE).

Key Technical Topics:

• The Merkle DAG Architecture: Why every capital or tax figure must be a node in a hash tree to prevent "silent drift".
• FRTB Standardised & Internal Models: Handling sensitivities, default risk, and liquidity horizons with regulator-template exports.
• GloBE Article 5 Walks: Navigating the jurisdictional top-up process from book profit to GIR XML export.
• QDMTT / IIR / UTPR Routing: How the engine uses OECD-published facts to determine exactly which jurisdiction collects top-up tax.
• Self-Hosted Governance: Deploying Postgres + FastAPI + React within your own network to ensure data residency and security.

• For FRTB: frtb.orbaos.com
• For GloBE: globe.orbaos.com

"Your regulator can replay our exports offline with a single Python file. No backend access required."

• 05:00 – 12:00 | The Reconciliation Crisis: Why FRTB and Pillar Two Programs Fail: A deep dive into the operational failure modes where Risk, Finance, and Audit cannot agree on input rows. Discussing why "most FRTB programmes don’t fail on the math — they fail on reconciliation".
• 12:00 – 22:00 | The Doctrine: Admissibility Before Calculation: Technical breakdown of the Merkle DAG and the hash-echo commit flow. Explaining why "admitted before calculated" is the core governing principle of the engine.
• 22:00 – 32:00 | FRTB Specialist Segment: SA, IMA, and Regulator-Ready Exports: Walkthrough of the SBM, DRC, and RRAO modules, alongside the Internal Models (IMA) pipeline including Expected Shortfall and RFET. How exports map to PRA, EBA, and APRA templates.
• 32:00 – 42:00 | Pillar Two Specialism: Article Walks and Top-Up Routing: Detailed navigation of the Article 3.2 and 4.1 walks, Article 9 safe harbors, and the deterministic routing of QDMTT, IIR, and UTPR based on OECD Central Record facts.
• 42:00 – 47:00 | Operational Governance: The Warn-Gate-Block Path: How to deploy the system without breaking legacy paths. Moving from observational logging to strict four-eyes control and eventually "fail-closed" production.
