waitForHealthy's 3 s settle / 5 s poll / 90 s timeout become package vars (production values unchanged, pinned by TestR488_HealthWaitDefaultsAreProduction); TestMain shortens them once. Measured before: 51 of 599 tests held 442 of 444 s, two not-running fixtures 279 s alone. newOffboxManager now installs a failing SSH fake: TestOffbox_ConfirmedReset was spawning a real 'ssh felhom@nas.local' and waiting out its 10 s ConnectTimeout.
