"fuzzy" (default): checks each name against the primary SDN_Name field, OFAC's own a.k.a./f.k.a. aliases (both the structured alias export AND aliases embedded in the remarks field), using exact matching, common transliteration folding (c/k, v/w, y/i/j, and more), and a one-to-one per-token typo-tolerant score (see fuzzyThreshold). Live-benchmarked recall 97.6%, false-hit rate 3.5% (see README). This is additive over the old behavior - every match "exact" mode would have found, it still finds, plus new alias/transliteration/near-miss matches. "exact": restores the original, literal case-insensitive substring-only matching against SDN_Name alone (no aliases, no fuzzy scoring) - use this if you need output identical to this actor's pre-2026-09-24 behavior.
