Questions before architecture

What the principals establish first.

01
What material may be indexed, retrieved, quoted, or excluded?
02
How are matter, client, jurisdiction, and ethical-wall boundaries enforced?
03
Can every answer return to the source passage and access decision?
04
What happens when the system is uncertain, incomplete, or asked for a conclusion?
