ARCHITECTURE:
- Windows: dedicated WSL2 distro with fixed VHDX, Docker inside
- macOS: Lima VM with fixed disk, Docker inside
- Linux: sparse ext4 loopback image, Docker data-root inside
NEW FILES:
- vm-provisioner.js: core provisioning engine (create/start/destroy/export)
- Disk presets: Minimal(10GB), Balanced(30GB), Power(100GB), Custom
- Sparse images that grow on demand (start at ~0 bytes)
- Full lifecycle: provision → deploy DashCaddy → destroy (clean removal)
- Data export before uninstall for users who want to migrate
- vm-ipc.js: Electron IPC handlers connecting wizard to provisioner
- vm:provision, vm:destroy, vm:get-status, vm:export-data, vm:get-presets
- disk-budget-step.js: wizard UI step with preset cards + custom slider
- Real-time free space check against selected disk size
- Plain English description of what each tier handles
UPDATED:
- caddyfile-generator.js: docker-compose now includes disk safety env vars
(health retention, stats caps, memory limits) as defense-in-depth
even inside the VM sandbox
GUARANTEE: DashCaddy physically cannot exceed the storage budget.
The OS enforces the limit at the disk/image level, not our code.
