Root Operational Bottleneck
Commodity and counterparty exposure is tracked in a limit workbook refreshed from position exports, so a same-day trade can breach a limit the sheet has not seen.
Control Hazard & Audit Exposure
A counterparty limit is breached because the exposure sheet missed a same-day trade, and the next trade still clears against a stale remaining limit.

Exposure Telemetry Monitor that Blocks Trades When Counterparty Limits Are Breached
Exposure telemetry monitor that accumulates live positions by counterparty and blocks a new trade when the remaining limit would be exceeded.
Continuous Assertion Rule
Exposure assertion: a trade cannot book if it would put counterparty or commodity exposure above the policy limit in force on the trade date.
