wren leaves unnamed areas to the assistant; assistant targets take a closed set of values

wren drops a call on an area the command does not name (other than the
user's or, with none named, the living room): "switch on the appliances"
turned on the bathroom light at 0.97. The assistant's `values` setting gives
a str target its only values, explains them in the tool and confirms in the
word set for each ("Canopy open.").

 never the tools the chat's assistant uses. Its instructions list the context
