narrowHint property
How to get from many matches to one, flavored per host.
A scenario author edits the app and retypes the call, so a Key and a
Finder are the right answers. An agent driving a live app can do
neither — it cannot add a key to a running app and has no Finder to
pass — so the default advice was a refusal that told it to do the one
thing it could not do. It has nth and item; the message says so.
Implementation
final String narrowHint;
