Use this when you have a company and need the reason and the proof. Costs 1 unit. `evidence` covers the last `lookback_days` days (default 365, max 1825); `last_event` is ALWAYS the most recent event on record whatever its age, with `within_lookback` saying whether it also appears in `evidence`. So an empty `evidence` with a populated `last_event` means the company is known and simply quiet — widen `lookback_days` to bring it in. `resolved:false` means we hold no such company at all, which is a different answer again. `resolution_confidence` (0-1) says how strongly the resolved name agrees with the domain asked about; treat anything below 0.67 as unconfirmed attribution.",
