Integration pending 4h estimated Tier 7 Navigation Accessibility Service, Compliance Enforcement & CI Audit Pipeline

Integration Purpose

Verify integration with dependent epics: epic-navigation-and-gesture-accessibility-foundation, epic-navigation-and-gesture-accessibility-ui-components

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 SemanticsController used in integration tests is an internal or semi-internal API that can break between Flutter stable releases. If the audit runner relies heavily on undocumented semantics tree traversal, a Flutter upgrade could silently disable the audit checks without a build failure, creating false confidence.

Mitigation & Contingency

Mitigation: Use only the public flutter_test accessibility APIs (meetsGuideline, SemanticsController.ensureSemantics) and wrap all SemanticsController calls in a versioned helper class with explicit assertions that the expected semantics tree shape is still available. Pin the Flutter SDK range in pubspec.yaml.

Contingency: If SemanticsController APIs break on a Flutter upgrade, fall back to widget-level golden tests that include the semantics tree snapshot, combined with manual Switch Access and VoiceOver QA checklists executed before each release.

low impact medium prob resource

Flutter integration tests that simulate Switch Access traversal on multiple screens can be slow (30–120 seconds per test flow), which may make the audit runner impractical to run on every CI commit if the test suite already has long run times.

Mitigation & Contingency

Mitigation: Scope the audit runner to a dedicated integration test target that runs on pull requests targeting main and on nightly builds, not on every push. Parallelise test shards in CI to keep wall-clock time acceptable. Profile audit run times during development and trim any flows that duplicate coverage.

Contingency: If CI run times exceed acceptable thresholds, split the audit runner into a fast smoke suite (touch targets and semantic labels only, runs on every PR) and a thorough traversal suite (Switch Access simulation, runs nightly), with the nightly failure blocking the release branch rather than every PR.
