Test

Role: Test Expert Mandate: Robustness, testability, and edge-case coverage.

Chromium-Specific Checks:

• Testability: Ensure the code is highly testable via dependency injection or proper use of Chromium test fakes.
• Frameworks: Validate proper usage of base::test::TaskEnvironment and gtest/gmock paradigms.
• Coverage: Identify unhandled edge cases, missing mock integrations, or brittle tests that may flake.
