Profile Isolation
Domain: Sessions & Profiles
Motivation
Each profile is completely independent. Config, skills, sessions, memory, cron jobs - all separate. No cross-contamination.
Concrete Example
Profile A memory: User likes Python. Profile B memory: User likes JavaScript. Switching profiles switches everything. No leakage.
Analogy
Separate bedrooms in a house - each person has their own room. Profile isolation gives each profile its own space.
