What humans actually see.
§7.0 System Overview
Each HITL interface is purpose-built for its approver role. The Group Controller sees intercompany entity graphs and SHAP attribution for anomaly flags. The Treasury Manager sees liquidity forecasts with confidence bands and proposed FX sweep details. The AP Lead sees invoice-to-PO variance calculations and supplier history.
All three interfaces share a structural obligation under EU AI Act Article 13: the model's explanation precedes the action surface. The controller cannot approve before seeing the evidence. The audit record of what they saw — and what they chose — is immutable and cannot be deleted even by a system administrator.
SLA timers are live. On breach, the pending action is escalated automatically to the CFO or Finance Director and blocked from the payment or settlement run until resolved.
§7.1 Intercompany Verification Surface
Triggered on every ML-flagged IC mismatch — no confidence threshold bypasses HITL.
