BUILT 2026-09-23: the Served tier runs NIGHTLY at 02:00 (GitLab schedule 1, Europe/Berlin), skipped on pushes (manual start possible). The job pauses the SPICE task, runs guard.ps1 -MinFreeMb 4500 (backup window 03:00-05:00 still enforced), runs the Served suite, and always resumes SPICE. Schedule created inactive; the one-time task "SPICE Nightly Served - activate" switches it on 2026-09-23 12:00, first run 2026-09-24 02:00 (the operator moves the PC out of the bedroom first). DONE WHEN the first nightly run is green and SPICE is back afterwards. Runbook: /sites/Projects/Pages/CICD-Runbook.
