Deflake a flaky test

A deflake: issue names ONE test that has been observed failing and then passing on a rerun of the same commit — the definitive flaky signature. Your job is to make that test deterministic without changing what it verifies.

The issue body carries the test identity (file + name) and the observed failure signature (e.g. Test timed out in 5000ms, Timed out waiting for …, an order-dependent assertion, a wall-clock/random-dependent value). Read the test, reproduce the mechanism in your head, and apply the SMALLEST fix from the allowed set below that removes the nondeterminism.
