 Architecture diagrams go stale because they are pictures. In radical.tools they are **views of one model**. Every element lives once, and the canvas, dependency matrix, sequence diagram, table and wiki all read from it. The decisions, requirements and fitness functions that explain the architecture live in the same model, linked to the elements they govern.

 - **C4 without the busywork.** Smart Layout places nodes, minimises crossings and fits groups for you.
 - **From a paragraph to a model.** Radical Forge turns a system description into requirements, fitness functions, Gherkin scenarios, UI mockups and a C4 model, one reviewable stage at a time.
 - **Bring your own AI.** OpenAI, Anthropic, Gemini, or a local model through Ollama.

-> The installers are not code-signed yet.
-> **macOS:** if the app "is damaged" or "can't be opened", run `xattr -cr /Applications/radical.studio.app` once.
-> **Windows:** SmartScreen may warn about an unknown publisher. Choose *More info → Run anyway*.
+**Desktop app:** there are no prebuilt installers yet. To run it as an Electron app, build it from source (see [Getting started](#getting-started)): `npm install && npm run dist` produces an installer for your OS in `dist/`.
 
 **VS Code:** an extension that opens `.radical` files right in the editor lives in [tools/vscode-radical](tools/vscode-radical).
