The B20-only rug vector: a token can launch clean and later attach a sender blocklist (PolicyUpdated) — silently becoming seizable via burnBlocked. This reads the token's full policy/pause event timeline (CDP-indexed onchain events) plus the live policy state, and tells you if — and exactly WHEN — it turned seizable.
