+title: Infrastructure architecture
+description: The decentralized orchestration model and deployment structure.
+weight: 10
+---
+
+The Root framework operates on a decentralized orchestration model designed for independent, self-contained projects. It enforces a strict separation between the orchestrator (the "brain") and the automation tasks (the "muscle").
+
+## Core philosophy {#philosophy}
+
+The framework is built on the **Smart Root, Stupid Actions** principle. This design ensures that individual automation scripts remain declarative and unaware of the global system state, while the central dispatcher handles environment resolution and library initialization.
+
+### Smart Root (The Dispatcher)
+
+The `root` entrypoint is the sole interface for users. It is responsible for:
+
+- **Environment resolution** → Locating the `commons` and `configs` repositories.
+- **Library warming** → Sourcing namespaced modules exactly once.
+- **Context establishment** → Defining the target [Node](/root/glossary#node) and its associated paths.
+
+### Stupid Actions (The Tasks)
+
+[Actions](/root/glossary#action) are declarative scripts located in `scripts/actions/`. They are "stupid" because:
+
+- They do not calculate paths or detect repositories.
+- They depend entirely on the `ROOT_` environment variables.
+- They focus exclusively on a single atomic task (e.g., `compose`, `ufw`).
+
+## Deployment model {#deployment}
+
+The framework is typically deployed as a shared [Commons](/root/glossary#commons) repository mounted as a Git submodule within a configuration repository. The engine powering this shared infrastructure is hosted at [GitHub: ermnvldmr.com-root-commons](https://github.com/deytenit/ermnvldmr.com-root-commons).
