Part-way through a run, the system decides what to build: which surfaces the answer needs, and how many.
Why you would want to see it
Left alone it decides and proceeds, which is usually what you want. But it is also the moment where a task can widen more than you intended, and the one point where a small correction saves the whole run.
Asking to be asked
Turn on Ask for permission at interface selection in directory settings. The run then pauses at that point and shows you what it intends to build before it builds it.
You can let it proceed, or stop it.
The gate offers a "Continue, don't ask again" action. Taking it turns the setting off for the directory — that is the same switch, not a one-off.
Why it chose what it chose
The choice is driven by the shape of the answer, not by your phrasing. A comparison becomes a table or cards; a sequence becomes a timeline or board; a model becomes a sheet.
If it picked badly, you can move a result to another surface afterwards — see Reviewing an interface.
