`update_app_config()` now called on fast path in `_swap_database()`, so preference changes (e.g. READ_ACCESS) propagate immediately across workers. See [[Design/Resolver]].

### Admin UI cleanup (otterwiki fork)
-
- **Mail preferences tab** still visible in PLATFORM_MODE — should be hidden (no SMTP in platform mode)
-
- **"Email" column label** on User Management page should say "Handle" in PLATFORM_MODE
-
- **"Approved" checkbox** semantics unclear in platform context — investigate what APPROVED access level means for per-wiki users and whether the checkbox is relevant
All three items were completed during Phase 2 User Management work: mail tab hidden (`@platform_mode_disabled` + nav guard), "Email" → "Handle" conditional in templates, "Approved" checkbox replaced by Role dropdown (Admin/Editor/Viewer) with `is_approved` auto-set. Tests cover all three.
### No navigation from wiki to dashboard
No way to get from within a wiki back to the platform dashboard. **Plan at [[Plans/Wiki_To_Dashboard_Navigation]].** One template change in otterwiki fork.
