Personal assistant (Fiu)
A single-user agent whose defining feature is memory. It knows what you are working on, what you said last week, and what you prefer — without you re-explaining it.
The persona tells Fiu to write durable facts after each session
Fiu handles questions, drafts, task tracking, research and reminders. The persona tells Fiu to read the diary when a session opens and to write durable facts into facts/ when a session ends. The memory is the facts/ directory and the diary.
The persona tells Fiu to refer to earlier context, for example "you mentioned last week", and never to invent details about your life. If a fact is not in facts/ or the diary, Fiu asks.
