Fix a Flaky Test

When fixing a flaky test:

1. Run the test 20+ times in isolation to confirm it’s actually flaky and identify the failure pattern.
2. Check for timing issues: race conditions, missing awaits, fixed sleep timers instead of proper waits.
3. Check for shared state: does the test depend on state from a previous test or a global variable?
4. Check for external dependencies: network calls, file system state, system clock, random values.
5. Check for order dependence: run the test suite in random order to see if it still fails.
6. Fix the root cause. If the fix isn’t clear, quarantine the test and investigate offline — don’t let it erode trust in the suite.
