 ## Review risks (know before submitting)
 
-- **Always-location (5.1.1)** — the #1 question. The feature is visible
-  (Alerts tab) and opt-in; the review notes above say so explicitly.
+- **Always-location (5.1.1 / 2.5.4)** — the feature is visible (Alerts tab)
+  and opt-in; the app does not declare persistent background location mode,
+  and the review notes describe region monitoring/significant-change rather
+  than continuous tracking.
 - **Reviewer outside the UK** — empty radius; mitigated by the empty-state
   task above + review notes.
 - **"Cheapest" claims (2.3.1)** — mitigated by the OGL/footnote task.
