Architecture Overview

Code Editor Land is structured as 15 independent Elements - self-contained Rust crates and TypeScript packages that each handle a specific concern.

Layer 1 - Native Shell

Element	Role
Mountain	Window, file system, and process management (Tauri)
Air	Update, download, and crypto signing daemon

Element	Role
Vine	gRPC protocol definitions and implementation
Mist	WebSocket communication layer

Element	Role
Cocoon	Runs VS Code extensions via Effect-TS
Grove	Native WASM and Rhai extension host
Worker	Web Workers for frontend tasks

Element	Role
Wind	Re-implementation of the VS Code Workbench
Sky	Astro UI component layer

Element	Role
Rest	JS bundler for VS Code platform code (OXC-based)
Output	Bundled JS artifacts produced by Rest
SideCar	Pre-built Node.js binaries for cross-platform use
Maintain	CI/CD and maintenance scripts

User interaction
  → Mountain (native window event)
  → Vine (gRPC IPC)
  → Cocoon (extension host)
  → Wind (workbench state)
  → Sky (render)
