Test coverage gaps

[harperreed]

Problem

While there are unit tests, there are significant gaps:

• Many components lack meaningful test coverage
• Core utilities like storage have only basic happy path tests
• Missing tests for error conditions and edge cases
• No end-to-end or integration tests for critical user flows

Impact

Higher risk of bugs, harder to refactor with confidence, poor development velocity.

Acceptance Criteria

• Achieve 80% test coverage across all components
• Add comprehensive tests for storage utilities
• Implement tests for error conditions and edge cases
• Add integration tests for critical user flows
• Set up automated test coverage reporting

Priority

Medium - affects code quality and maintainability
