Bulk Address Screener

Takes a list of addresses — pasted, uploaded, or pulled straight off the page you are looking at — and checks each one: is it a contract or a wallet, how large is the code, and how many days ago was it deployed, found by binary search rather than scanning. It also cross-references a known-bad list you supply. Nothing is bundled, because a stale built-in sanctions list gives false confidence. The check that only works in bulk is lookalike detection: two addresses sharing their first four and last four characters is how a poisoned address gets copied instead of the real one, and that pattern is completely invisible when addresses are checked one at a time. Runs four at a time with progress, and reports age as a signal rather than a verdict.
