I'd like to work on this task. As a software engineer experienced with end-to-end testing, backend workflows, and reliability validation, I can build comprehensive E2E coverage for the notification lifecycle.

I will implement tests covering notification creation, delivery processing, retry behavior, and failure handling scenarios. The test suite will validate core workflows, edge cases, and ensure critical regressions are detected before release.

The PR will include the E2E tests, CI validation, test documentation, and execution results.
