Scenario: Agent Screens, Then Designation

The freshness-race scenario - screen at sign, version every result.

The setup

Your agent screens a counterparty at 10:00 - clean. OFAC designates the wallet at 10:30. The agent signs the payment at 11:00 without re-screening.

The gap

• The screen result is stale - logged against an earlier list version
• The payment settles to a now-designated wallet
• Designations land between releases - this is the freshness race

The control

1. Screen at the moment of signing, not earlier in the flow
2. Record the list version with every result
3. Re-screen when the flow spans time (queue delays, approvals)
4. Hourly sync keeps the list current

The takeaway

A screen is a point-in-time result against a specific list version. Screen at sign, version every result, and re-screen when time passes.
