 - **Workstation:** Beelink SER9 Pro+, 32 GB, Windows 11 Pro. Backup: ThinkPad X13 Gen 3
 - **Editors:** VS Code for everything except QBI, which needs Visual Studio for the Windows Forms designer
-- **Build VM:** a complete Windows 11 build environment in VirtualBox, exported and backed up to several drives (`devdocs/build/DEV-VM-SETUP.md`)
+- **Builds:** releases are built on the workstation; the backup laptop is the fallback. A VirtualBox build VM (`devdocs/build/DEV-VM-SETUP.md`) was set up in early 2026 but is deprecated: going fully virtual could not cover QBI and some other parts
 - **Source control:** Git on a self-hosted Gitea on DigitalOcean. Moved from SVN in early 2026
 - **Location:** off-grid, Starlink internet, solar power. The workstation is not left running overnight in winter, so do not plan work that depends on overnight runs on it
