+# infra-run/ansible/inventory
+
+This directory is intended for Ansible inventory definitions. It separates shared variables from host-specific values to support clean environment modeling and safer automation.
+
+## Diagram
+
+```mermaid
+flowchart TD
+  A["inventory"] --> B["group_vars"]
+  A --> C["host_vars"]
+  B --> D["Shared environment variables"]
+  C --> E["Per-host overrides"]
+```
+
+## Scope
+
+- `group_vars` - variables applied at group or environment level.
+- `host_vars` - variables tailored to individual nodes.
+
+## Notes
+
+- The structure is present even though the repository currently keeps this area sanitized and mostly empty.
+- This is the natural companion to future playbooks and roles under `infra-run/ansible`.
