Missing deferred MOSC cleanup when CleanupMCPOnly is used. Both tests create the MOSC through the shared environment but register only CleanupMCPOnly, and delete the MOSC inline later in the test body. If any assertion before that deletion fails, the MOSC survives, OCL stays enabled on the infra pool, secrets and the machine-os-builder deployment leak, and SkipTestIfOCBIsEnabled skips the remaining OCB tests in the same run.

  • test/extended-priv/mco_ocb.go#L28-L31: replace defer env.CleanupMCPOnly() with defer env.Cleanup(), or add defer env.MOSC.CleanupAndDelete().
  • test/extended-priv/mco_ocb_longduration.go#L278-L281: add defer env.MOSC.CleanupAndDelete() after defer env.CleanupMCPOnly(), matching Lines 340-342.
