get_signal

Fetch one signal by its id, when you already know which one you want. Every other read tool returns a set and bounds it, so re-reading a single row through them means re-running a query and hoping the row survives the row budget a second time; this returns that row and nothing else. Takes either the full correlation id or the short handle in column 2 of any CWF row — cite the handle, pass it back here. The live window turns over in about two minutes, so a signal read several calls ago may have aged out; the error says which of the two happened rather than leaving you to look for a typo. To find signals rather than re-read one, use search_signals or scope_signals; to reach the ones about the same subject, use get_related_signals.
