-Version: 1.7.1 (Simplified Workflow)
+Version: 1.9.0 (Security & RBAC Mandate)
 Changes:
- Simplified Generation Workflow to a single phase: Code Generation from `tasks.md`.
- Removed multi-phase Architecture/Implementation split to streamline development.
+- Added Principle IX: Security & Access Control (Mandating granular permissions for plugins).
 Templates Status:
- .specify/templates/plan-template.md: ✅ Aligned (Dynamic check).
+- .specify/templates/plan-template.md: ✅ Aligned.

 ### VII. Everything is a Plugin
 All functional extensions, tools, or major features must be implemented as modular Plugins inheriting from `PluginBase`. Logic should not reside in standalone services or scripts unless strictly necessary for core infrastructure. This ensures a unified execution model via the `TaskManager`, consistent logging, and modularity.

+### VIII. Unified Frontend Experience
+To ensure a consistent and accessible user experience, all frontend implementations must strictly adhere to the unified design and localization standards.
+- **Component Reusability**: All UI elements MUST utilize the standardized Svelte component library (`src/lib/ui`) and centralized design tokens. Ad-hoc styling and hardcoded values are prohibited.
+- **Internationalization (i18n)**: All user-facing text MUST be extracted to the translation system (`src/lib/i18n`). Hardcoded strings in the UI are prohibited.
+
+### IX. Security & Access Control
+To support the Role-Based Access Control (RBAC) system, all functional components must define explicit permissions.
+- **Granular Permissions**: Every Plugin MUST define a unique permission string (e.g., `plugin:name:execute`) required for its operation.
+- **Registration**: These permissions MUST be registered in the system database during initialization or plugin loading to ensure they are available for role assignment in the Admin UI.
