+
+Immutable system core - minimal Ubuntu 24.04 with essential services.
+
+## Components
+- Linux kernel 6.8+
+- Systemd init
+- NetworkManager
+- PipeWire audio
+- Basic filesystem utilities
+
+## Stability Promise
+5-6 year LTS support. Base layer changes only for security patches.

+# Linux Development Runtime
+
+Tools for running Linux development tasks without polluting base OS.
+
+## Components
+- Docker CE
+- VSCode (or VSCodium)
+- Git
+- Build tools (gcc, make, cmake)
+- Node.js, Python, Rust
+- Podman (alternative to Docker)
+
+## Isolation Strategy
+Dev workspace runs in containers, pinned to specific Gen-1 version.
+Base OS stays clean and stable.

+
+Compatibility layer for running Windows .exe applications.
+
+## Components
+- Wine 9.0+ (stable)
+- Proton (for games)
+- DXVK (DirectX to Vulkan)
+- Windows fonts (Arial, Times New Roman, etc.)
+
+## Execution Policy
+1. Try Wine (fast, no Windows license)
+2. Fall back to VM if needed (QEMU/KVM)
+3. Remote host as last resort
+
+## File Associations
+.exe, .msi, .bat → wine-launcher
