## Fixes Applied (2026-01-21)

1. Renamed `get_authenticated_user` → `find_authenticated_user` (returns `Option<User>`)
   - `repository/user/find.rs:127`
   - `services/user/mod.rs:50-51`

2. Renamed `get_with_sessions` → `find_with_sessions` (returns `Option<UserWithSessions>`)
   - `repository/user/list.rs:8`
   - `services/user/mod.rs:54-55`

3. Renamed `get_ban` → `find_ban` (returns `Option<BannedIp>`)
   - `repository/banned_ip/queries.rs:24`
   - Also updated caller: `entry/cli/src/commands/admin/users/ban/check.rs:26`

4. Extracted hardcoded `30` days to constant
   - Added `const ANONYMOUS_USER_RETENTION_DAYS: i32 = 30;` in `jobs/cleanup_anonymous_users.rs`
