Integration checkpoint for epic-receipt-capture-and-attachment-ui-accessibility
epic-receipt-capture-and-attachment-ui-accessibility-integration-task — Integration Task
Integration Purpose
Verify integration with dependent epics: epic-receipt-capture-and-attachment-foundation, epic-receipt-capture-and-attachment-core-logic
This integration checkpoint ensures proper coordination and compatibility between different epics. It verifies that all interfaces, data flows, and dependencies are correctly implemented before proceeding.

Flutter's accessibility live region support (SemanticsProperties.liveRegion) has known inconsistencies between iOS VoiceOver and Android TalkBack, and between Flutter versions. Threshold-crossing announcements may fail to fire or double-fire, breaking the accessibility contract for Blindeforbundet users.
Mitigation & Contingency
Mitigation: Test live region announcements on physical devices with VoiceOver and TalkBack enabled from the first iteration. Use the AccessibilityLiveRegionAnnouncer component pattern already established in the project. Verify announcement timing relative to Bloc state emissions to avoid double-fires.
Contingency: If Flutter live regions prove unreliable, implement a platform-channel fallback that calls UIAccessibility.post(notification:) on iOS and AccessibilityManager.sendAccessibilityEvent() on Android directly, bypassing Flutter's abstraction.
The org-configurable threshold must be available at form-render time. If the threshold configuration is fetched asynchronously and not cached, the indicator may briefly show the wrong state (e.g., 'optional' before the threshold loads), confusing users and potentially allowing invalid submissions.
Mitigation & Contingency
Mitigation: Ensure the receipt threshold validator loads and caches the org configuration at app startup or organization selection time, not lazily on form open. Use a loading state in the indicator widget rather than defaulting to 'optional' while configuration is pending.
Contingency: If startup caching is not feasible, treat an unknown threshold as 'receipt required' (fail safe) and surface a clear loading indicator until the configuration resolves, preventing invalid submissions while the config loads.
