ai.newnal.illi.private ยท 3- ai.newnal.illi.private.custodyKey record not from the namespace authority The root admin's X25519 custody private key for one home (rkey = homeId), kept in their Private Sphere so logging out or reinstalling the app does not lose it; the app caches it in the Keystore/Keychain.
- ai.newnal.illi.private.parentCredential record Custody record kept by a home's root admin in their own Private Sphere: the credentials of one of the home's parent accounts, generated on the ILLI device and handed over through the Service Agent Node at link time. rkey <homeId>-<slot>. Used to restore a parent account on a replaced device.
- ai.newnal.illi.private.phoneKey record The author's own Private Phone account, kept in the author's Private Sphere so a reinstalled app, a reset device or a replaced device restores the same Matrix identity. One per person: rkey self (earlier records used rkey = homeId and carry home).
