Integration checkpoint for epic-no-access-screen-ui
epic-no-access-screen-ui-integration-task — Integration Task
Integration Purpose
Verify integration with dependent epics: epic-no-access-screen-foundation, epic-no-access-screen-access-control
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 live region (SemanticsProperties.liveRegion) announcement may be delayed or swallowed by the OS accessibility engine if the Semantics tree is not fully built when the screen mounts, causing screen-reader users to miss the denial announcement.
Mitigation & Contingency
Mitigation: Trigger the live region announcement from a post-frame callback (WidgetsBinding.addPostFrameCallback) to ensure the Semantics tree is committed before the announcement fires. Test on both VoiceOver (iOS) and TalkBack (Android) physical devices.
Contingency: If live region timing is unreliable, fall back to using SemanticsService.announce() directly in the initState post-frame callback, which provides more deterministic announcement timing.
The organisation logo may fail to load (network error, missing asset) leaving a broken image in an otherwise functional screen, degrading the professional appearance and potentially confusing users.
Mitigation & Contingency
Mitigation: Wrap the logo widget in an error builder that renders a styled fallback (organisation name text or a generic icon) when the logo asset or network image fails to load.
Contingency: If logo loading is persistently unreliable across organisations, remove the logo from the no-access screen entirely in favour of a text-only header using the organisation's display name from the design token system.
