// The Docker set's "first seen" is stamped by the evaluate tick, not by a page view: two healthy night Docker steps that
// happen while nobody opens the System page count. Before 2026-10-05 the stamp was taken only by DockerStatus on the
// page, so nights before the first view were lost (and the page test flaked on a second boundary).
// Red-proof: drop the DockerStatus call from Evaluate — the final status still waits ("0 of 2" / "1 of 2").
