Profiles, Preferences & User Data
Split the user record into identity, profile and preference data, and say why the three have different durability and privacy rules.

The User Lifecycle State Machine
Draw the states a user moves through - anonymous, registered, verified, active, dormant, suspended, deleted - and name what each transition must do to sessions and grants.
- 03.03
Account Changes, Merging & Recovery
Handle an email change, a duplicate account and a merge without losing ownership of the objects the old identity created.
- 03.04
Privacy, Data Export & Deletion
Enumerate everywhere one user's data lives - primary tables, derived tables, caches, logs, analytics, backups - and say which of those a deletion request can and cannot reach.
