Contact Detail & Edit

Accurate contact records are foundational to Bufdir-compliant activity reporting - every logged activity references a contact, and incorrect data propagates into organizational reports. The in-app edit capability lets coordinators correct contact information in the field without routing changes through the admin portal, reducing administrative bottlenecks and improving data quality. NHF's duplicate-activity detection and Barnekreftforeningen's caregiver workflows both depend on contacts being precisely maintained. Optimistic mutations with rollback also directly support the offline-first architecture requirement described in the mobile app specification.

Two coordinated Flutter screens sharing a ContactRepository Riverpod provider backed by Drift. The detail screen uses read-only widgets built from the design token system for consistent WCAG-compliant styling. The edit screen applies FormField-level validation with inline error text satisfying WCAG 3.3.1. Optimistic mutations write to the local Drift database immediately and enqueue a PATCH to the mutation outbox; on API error the local record is rolled back and a toast shown. Role guards built with the Role Guard Service prevent peer mentors from accessing coordinator-only fields. All fields must have semantic accessibility labels and ≥24×24 px touch targets.
