Root Operational Bottleneck
Net FX exposure is measured in a treasury workbook that re-keys entity balances and hedge notionals, so coverage is whatever last week's paste produced.
Control Hazard & Audit Exposure
Unhedged currency exposures hit the P&L after a rate move because the coverage matrix was not refreshed to current balances and hedge trades.

Position Telemetry Monitor that Flags FX Exposure Against Policy Limits
Position telemetry that reads entity balances and hedge notionals, computes net exposure by currency, and flags any pair above the policy limit.
Continuous Assertion Rule
Exposure assertion: each currency's net exposure must equal booked balances minus hedge notionals from the trade register, and a pair above the limit is escalated before the next session.
