Contacts

Contacts are the primary operational entity around which every peer mentor's day revolves - activities, notes, assignments, and reports all link back to a contact. Without fast, reliable contact list, search, and edit capabilities, the entire activity registration flow collapses, because mentors cannot find the person they are logging an interaction for. Basic search across contact and notes was flagged as a MUST in the prioritization matrix by all four organizations plus Norse Test. Merging list/search with detail/edit into a single feature also reduces UI fragmentation and accelerates MVP delivery, since these screens share the same contact data model, terminology overrides, and offline sync paths. A coherent contacts experience is the foundation that activity registration, notes, and proxy reporting depend on.

Implement on Flutter mobile using Riverpod for state and Drift+SQLCipher for offline-first persistence, with optimistic mutations and automatic rollback on failure. The contact list uses paginated queries against the REST API (`/api/v1/contacts`) with local cache fallback when offline. Search runs against the local Drift index first for instant results, then reconciles with backend results when connectivity returns. Display strings ("Contact", "My Contacts") MUST resolve through the Organization Labels system so per-tenant terminology overrides (e.g. NHF's "Familie") render correctly. All interactive elements must meet WCAG 2.2 AA: 24x24 touch targets, 4.5:1 contrast, semantic labels for VoiceOver/JAWS, keyboard navigation. Edit screens validate inputs, surface clear error messages with remediation hints, and queue mutations into the sync outbox when offline.
