01🪟A Window, Not a Second Pippa
0/5 lessonsThe first app whose user is Pippa, and the four things it refuses to become
Oriel turns the usual family-app relationship around: its user is Pippa, and Dad oversees. This track sets the boundary before any camera is opened. Oriel is a window, not a second Pippa: no brain, no memory, no conversation of its own, nothing written into Master Chief, one narrow kind of sound and hands that never play on their own. It lives in Pippa's own macOS account because a camera grant belongs to a signed program in a GUI session; its engine is the single writer whether Pippa's door or Dad's page pressed the button; and its defaults were decided by measuring the real Mac, not by guessing.
