+# [DEF:Std:Architecture:Standard]
+# @TIER: CRITICAL
+# @PURPOSE: Core architectural decisions and service boundaries.
+# @LAYER: Infra
+# @INVARIANT: ss-tools MUST remain a standalone service (Orchestrator).
+# @INVARIANT: Backend: FastAPI, Frontend: SvelteKit.
+
+## 1. ORCHESTRATOR VS INSTANCE
+*   **Role:** ss-tools is a "Manager of Managers". It sits ABOVE Superset environments.
+*   **Isolation:** Do not integrate directly into Superset as a plugin to maintain multi-environment management capability.
+*   **Tech Stack:** 
+    *   Backend: Python 3.9+ with FastAPI (Asynchronous logic).
+    *   Frontend: SvelteKit + Tailwind CSS (Reactive UX).
+
+## 2. COMPONENT BOUNDARIES
+*   **Plugins:** All business logic must be encapsulated in Plugins (`backend/src/plugins/`).
+*   **TaskManager:** All long-running operations MUST be handled by the TaskManager.
+*   **Security:** Independent RBAC system managed in `auth.db`.
+
+## 3. INTEGRATION STRATEGY
+*   **Superset API:** Communication via REST API.
+*   **Database:** Local SQLite for metadata (`tasks.db`, `auth.db`, `migrations.db`).
+*   **Filesystem:** Local storage for backups and git repositories.
