Answer
How should AI use project memory?
A direct answer about context scope and project memory for AI assistants.
Answer
AI should use the narrowest memory scope that answers the question. A general request may need no saved memory. A transcript question may need one source record. A client, patient, site, property, matter, or operation question may need one project. A pattern question may need broader saved work.
