      "description": "What this site holds about one address, in two independent halves. `listings` says what the token IS - the stock, its company, the issuer and the chain - and is present whenever the address is a listing we track. `matches` says what the CODE at the address is: its runtime bytecode hash, the implementation behind it if it is a proxy, and how many other addresses we track run byte-identical code; it is present only where we have read the code. The code half is reproducible: fetch eth_getCode and take its keccak256 and you get the same hash. Either half can be empty and both can be present; an address we hold nothing about returns found: false, which is an answer rather than an error. This never says an address is safe, genuine or correct, and there is no field that could: check it against the issuer before you act on it.",

THERE IS NO FREE-TEXT FIELD AND THERE WILL NOT BE ONE: a report is an enumerated kind plus a short subject, because the counts are what is useful and prose from an anonymous caller is a prompt-injection surface pointed at the people who read it. Nothing about you is recorded - no address, no header, no identifier - so a report cannot be joined to a caller and there is no reply.
