New Designation Screening Test Generator

This skill produces a spreadsheet that compliance teams can run through their sanctions screening system to verify two things at once:

1. Coverage — the screening list is current (catches names added in the most recent designations).
2. Fuzzy tuning — the screening engine is tuned to catch realistic name variations (transliterations, transpositions, alphabet swaps), not just exact strings.

Each row in the output is a single test entry: a designated name or a deliberate variation of one, plus the metadata an analyst needs to interpret a hit (or a miss).

When to run

Run when the user asks for:

• New designation test data / screening regression set
• Validation that their sanctions list is up to date
• A fuzzy-match calibration test set
• Anything matching "test my screening" or "check our [SDN/OFSI/EU] coverage"

If the user doesn't specify a lookback window, default to the trailing 7 days. If they say "since last run" and provide a prior date, use that.
