```

Start by reading testing/integration/ess/fips_test.go, especially the setup around the status checks and the system-event assertions shown in the failure log. Reproduce TestFIPS through the linked Buildkite analytics run and compare the failure examples. Done means the test no longer flakes during repeated integration runs and still verifies FIPS agent behavior.
