Run live agent pipelines across three financial scenarios. Inspect SHAP explanations, make HITL decisions, and watch every step land in an immutable audit trail.

System Architecture

Three pipelines.
One control plane.

Each financial scenario routes through a dedicated agent pipeline — IC Reconciliation, Treasury/FX, and AP Exception — converging on a shared HITL gateway, write-guard layer, and immutable audit store. SHAP explanations are computed before any human checkpoint per EU AI Act Art. 13.

Interactive Simulation

Run a live pipeline
end to end.

Select a scenario and entity. Press Run. Watch data events arrive, the pipeline light up sequentially, and make the HITL decision when the agent pauses for your review.

Scenario Anatomy

Three domains,
one decision model.

Each scenario is a distinct event class with its own ingestion format, feature set, and write-back target — but all converge on the same SHAP → HITL → Audit pattern required by regulation.

Regulatory Compliance

EU AI Act —
Article 13 by design.

Every pipeline is architected so that SHAP feature attributions are computed and committed to the audit store before any HITL checkpoint is presented. No human decision is made without a machine-readable explanation. This is not retrofitted — it is the sequence.

M Model Inference t = 0ms S SHAP Explain t + 120ms A Audit Pre-Write t + 250ms HITL BOUNDARY ← MACHINE ZONE (SHAP written) HUMAN DECISION ZONE → HITL Decision Human reviews W Write Guard E ERP / SAP Write ✓ Audit Closed ART.13 WINDOW: SHAP committed before HITL checkpoint opens ✓
EU AI Act · Art. 13 Transparency & Explainability SHAP feature attributions are written to the immutable audit store before the HITL checkpoint is opened. The human reviewer sees the top-3 drivers of every model decision before acting.
Implemented · SHAP before HITL
EU AI Act · Art. 14 Human Oversight Every pipeline contains a mandatory HITL node. No write-back to SAP, the bank, or the ERP can occur without an explicit Approve signal from an authorised user. Override routes to a manual correction queue.
Implemented · All paths gate on HITL
EU AI Act · Art. 17 Quality Management & Logging Every simulation produces an immutable Audit Record with: agent ID, scenario, entity, model score, SHAP values, HITL timestamp, decision, override reason (if any), and write-guard result.
Implemented · Full audit trail per run
