+    confidence: low
+    basis: No longitudinal consumer reliability measurement established by this review.

+Assessment: CUST-WP-0081, 2026-10-14. Relations identify interfaces to compose; they do not certify native integration. Existing external evidence levels are retained where present. New entries use conservative C1/R0 until consumer assessment exists.
