 ### 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.

+# Data Model: Frontend Navigation Redesign
+
+## Plugin Configuration
+
+The `PluginConfig` model is extended to support backend-driven navigation.
+
+```python
+class PluginConfig(BaseModel):
+    """Pydantic model for plugin configuration."""
+    id: str = Field(..., description="Unique identifier for the plugin")
+    name: str = Field(..., description="Human-readable name for the plugin")
+    description: str = Field(..., description="Brief description of what the plugin does")
+    version: str = Field(..., description="Version of the plugin")
+    ui_route: Optional[str] = Field(None, description="Frontend route for the plugin UI")
+    input_schema: Dict[str, Any] = Field(..., description="JSON schema for input parameters", alias="schema")
+```
+
+### ui_route
+
+- **Type**: `Optional[str]`
+- **Description**: Specifies the client-side route (URL path) where the plugin's custom UI is hosted.
+- **Behavior**:
+  - If `None` (default): The dashboard will open the plugin using the generic `DynamicForm` modal.
+  - If set (e.g., `"/tools/mapper"`): The dashboard will navigate (`goto`) to this route when the plugin card is clicked.
+
+## Backup Management (New)
+
+### Backup Types
+
+```typescript
+// frontend/src/types/backup.ts
+
+export interface BackupFile {
+    name: string;        // e.g., "prod-dashboard-export-2024.zip"
+    path: string;        // Relative path in storage
+    size: number;        // Bytes
+    created_at: string;  // ISO Date

+# Implementation Plan: Frontend Navigation Redesign
+
+**Branch**: `015-frontend-nav-redesign` | **Date**: 2026-01-26 | **Spec**: [specs/015-frontend-nav-redesign/spec.md](../spec.md)
+**Input**: Feature specification from `specs/015-frontend-nav-redesign/spec.md`
+
+**Note**: This template is filled in by the `/speckit.plan` command. See `.specify/templates/commands/plan.md` for the execution workflow.
+
+## Summary
+
+This feature redesigns the frontend navigation to shift from a Navbar-heavy approach to a Dashboard-centric model. Key changes include moving tool access (Mapper, Storage, Backups) to the Dashboard, simplifying the Navbar to global contexts (Tasks, Settings), removing deprecated features (Dataset Search, Environments), and implementing a dedicated Backup Management UI based on backend capabilities from feature 009.
+
+Additionally, the navigation architecture is refactored to be backend-driven. Plugins now expose a `ui_route` property, allowing the frontend to dynamically determine the correct navigation path without hardcoded mapping.
+
+## Technical Context
+
+**Language/Version**: Python 3.9+ (Backend), Node.js 18+ (Frontend)
+**Primary Dependencies**: FastAPI (Backend), SvelteKit + Tailwind CSS (Frontend)
+**Storage**: N/A (UI reorganization and API integration)
+**Testing**: Playwright (E2E - if available), Vitest (Unit)
+**Target Platform**: Web Browser
+**Project Type**: Web Application (Frontend + Backend)
+**Performance Goals**: Instant navigation (<100ms), fast dashboard load
+**Constraints**: Must maintain responsive design; Backup UI must interface with existing backend endpoints
+**Scale/Scope**: ~5-10 file modifications, 1 new major component (BackupManager)
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+- [x] **Semantic Protocol Compliance**: All new components will follow Svelte component header standards.
+- [x] **Causal Validity**: Contracts (props/events) will be defined before implementation.
+- [x] **Immutability of Architecture**: No core architectural changes; only UI reorganization.
+- [x] **Design by Contract**: New Backup component will define clear interface contracts.
+- [x] **Everything is a Plugin**: N/A (Frontend changes primarily, backend remains plugin-based).
+- [x] **Unified Frontend Experience**: All new UI components will use standardized components and internationalization (i18n).

+# Quickstart: Frontend Navigation Redesign
+
+## Overview
+This feature reorganizes the application navigation to be dashboard-centric and introduces a dedicated UI for Backup Management.
+
+## New Routes
+- `/tools/backups`: The new Backup Management interface.
+- `/`: Dashboard (updated with new tool links).
+
+## Removed Routes
+- `/tools/search`: Deprecated and removed.
+- `/settings/environments`: Deprecated and removed.
+
+## Development
+
+### Running the Backup UI
+1. Ensure the backend is running: `cd backend && uvicorn src.app:app --reload`
+2. Start the frontend: `cd frontend && npm run dev`
+3. Navigate to `http://localhost:5173/tools/backups`
+
+### Key Components
+- `frontend/src/components/backups/BackupManager.svelte`: Main container for backup operations.
+- `frontend/src/components/DashboardGrid.svelte`: Updated grid with new tool cards.
+- `frontend/src/components/Navbar.svelte`: Simplified navigation bar.
+
+## Verification
+1. Check Dashboard: Should see cards for Mapper, Storage, and Backups.
+2. Check Navbar: Should ONLY show Tasks and Settings.
+3. Check Backup Tool: Should load and display backup status/controls.

+# Research: Frontend Navigation Redesign
+
+## Decisions
+
+### 1. Backup Management UI Strategy
+**Decision**: Create a dedicated `BackupManager` component in `frontend/src/components/backups/`.
+**Rationale**: The requirement is to have a "full component" accessible from the dashboard. Separating it into its own directory ensures modularity and keeps the Dashboard component clean. It will consume the existing backup APIs (likely `/api/tasks` with specific backup types or a dedicated backup endpoint if one exists - *to be verified in Phase 1*).
+**Alternatives considered**: Embedding backup controls directly in the Dashboard (rejected: clutters the main view), reusing the TaskRunner component (rejected: need specific backup context/history view).
+
+### 2. Navigation State Management
+**Decision**: Use SvelteKit's layout system (`+layout.svelte`) and simple component props for Navbar state.
+**Rationale**: The Navbar changes are global. Removing items is a static change to the `Navbar.svelte` component. No complex state management (stores) is needed for this structural change.
+**Alternatives considered**: Dynamic config-based menu (rejected: overkill for this specific redesign).
+
+### 3. Deprecation Strategy
+**Decision**: Hard removal of "Dataset Search" and "Deployment Environments" components and routes.
+**Rationale**: The spec explicitly calls for removal. Keeping dead code increases maintenance burden.
+**Alternatives considered**: Hiding behind a feature flag (rejected: requirement is explicit removal).
+
+### 4. Dashboard Grid Layout
+**Decision**: Update `DashboardGrid.svelte` to include new cards for Mapper, Storage, and Backups.
+**Rationale**: Reusing the existing grid component maintains consistency.
+**Alternatives considered**: Creating a separate "Tools" page (rejected: spec requires access from main Dashboard).

+# Feature Specification: Frontend Navigation Redesign
+
+**Feature Branch**: `015-frontend-nav-redesign`
+**Created**: 2026-01-26
+**Status**: Draft
+**Input**: User description: "Я хочу провести редизайн фронта в части навигации. 1. Удалить Dataset Search (из Navbar и дашборда), Deployment Environments 2. Вкладку Tasks оставить для просмотра всех задач - убрать оттуда кнопку Run backup 3. Должен быть полноценный компонент бэкапов, как мы разрабатывали в 009-backup-scheduler. Доступ - из дашборда главного 4. Перенести ссылку на Dataset mapper из Navbar на дашборд 5. Перенести ссылку на Storage manager на дашборд Общая логика - на дашборде должны быть ссылки на полноценные инструменты, навбар - для настроек и общей Tasks"
+
+## Clarifications
+
+### Session 2026-01-26
+- Q: Do I need to build the Backup Management UI from scratch? → A: Yes, create the UI for backup using data from task 009-backup-scheduler.
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Centralized Tool Access via Dashboard (Priority: P1)
+
+As a user, I want to access all main tools (Backups, Mapper, Storage) from the main Dashboard so that I have a central hub for operations.
+
+**Why this priority**: This is the core of the redesign, shifting the navigation paradigm to a dashboard-centric model for tools.
+
+**Independent Test**: Can be tested by verifying the Dashboard contains links/cards for Backups, Mapper, and Storage, and that clicking them navigates to the correct full-page tools.
+
+**Acceptance Scenarios**:
+
+1. **Given** I am on the main Dashboard, **When** I look at the available tools, **Then** I see options for "Backup Manager", "Dataset Mapper", and "Storage Manager".
+2. **Given** I am on the Dashboard, **When** I click "Backup Manager", **Then** I am taken to the full Backup management interface.
+3. **Given** I am on the Dashboard, **When** I click "Dataset Mapper", **Then** I am taken to the Mapper tool.
+4. **Given** I am on the Dashboard, **When** I click "Storage Manager", **Then** I am taken to the Storage tool.
+
+---
+
+### User Story 2 - Simplified Navigation Bar (Priority: P1)
+
+As a user, I want a clean Navbar containing only global context items (Tasks, Settings) so that the interface is less cluttered and navigation is distinct from tool usage.
+
+**Why this priority**: Enforces the separation of concerns between "Global Status/Settings" (Navbar) and "Operational Tools" (Dashboard).
+
+**Independent Test**: Can be tested by inspecting the Navbar across the application to ensure removed items (Search, Mapper, Environments) are gone and only Tasks and Settings remain.
+
+**Acceptance Scenarios**:
+
+1. **Given** I am on any page, **When** I view the Navbar, **Then** I do NOT see links for "Dataset Search", "Dataset Mapper", or "Deployment Environments".
+2. **Given** I am on any page, **When** I view the Navbar, **Then** I see links for "Tasks" and "Settings".
+3. **Given** I am on the Tasks page, **When** I look for the "Run backup" button, **Then** it is NOT present (as it belongs in the Backup tool).
+
+---
+
+### User Story 3 - Deprecation of Unused Features (Priority: P2)
+
+As a user, I want removed features (Dataset Search, Deployment Environments) to be inaccessible so that I don't use deprecated workflows.
+
+**Why this priority**: Cleans up the UI and prevents confusion with features that are being removed or hidden.
+
+**Independent Test**: Verify that UI elements for Dataset Search and Deployment Environments are removed from both Navbar and Dashboard.
+
+**Acceptance Scenarios**:
+
+1. **Given** I am on the Dashboard, **When** I look for "Dataset Search", **Then** it is not visible.
+2. **Given** I am on the Dashboard or Navbar, **When** I look for "Deployment Environments", **Then** it is not visible.
+
+### Edge Cases
+
+- **Direct URL Access**: If a user attempts to access the URL of a removed page (e.g., `/search` or `/environments`) via bookmark or history, they should be redirected to the Dashboard or shown a 404 page (standard app behavior).
+- **Mobile View**: The simplified Navbar must remain responsive; with fewer items, it should likely avoid collapsing into a hamburger menu unless necessary on very small screens.
+
+### Assumptions
+
+- The backend logic and UI components for the "Backup Scheduler" (Feature 009) are available and ready to be integrated into the main Dashboard view.
+- Existing tools (Dataset Mapper, Storage Manager) function independently of the Navbar context and will work correctly when accessed via the Dashboard.
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: System MUST display "Dataset Mapper" entry point on the main Dashboard.
+- **FR-002**: System MUST display "Storage Manager" entry point on the main Dashboard.
+- **FR-003**: System MUST display "Backup Scheduler" (or similar name) entry point on the main Dashboard.
+- **FR-004**: System MUST provide access to the full Backup Management component (newly created based on feature 009 data) via the Dashboard link.
+- **FR-005**: Navbar MUST NOT contain links to "Dataset Search", "Dataset Mapper", or "Deployment Environments".
+- **FR-006**: Dashboard MUST NOT contain "Dataset Search" widget or link.
+- **FR-007**: Tasks page MUST NOT show the "Run backup" button (backup initiation moves to Backup tool).
+- **FR-008**: Navbar MUST retain "Tasks" and "Settings" links.
+- **FR-009**: Backup Manager MUST support configuring automated backup schedules (enabled/disabled, cron expression) per environment.
+- **FR-010**: Backup List MUST provide a "Go to Storage" action that navigates to the Storage Manager with the correct path selected.
+
+### Key Entities
+
+- **Dashboard**: The main landing page serving as the registry for tools.
+- **Navbar**: The persistent top navigation for global application state/config.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: Users can navigate to Dataset Mapper, Storage Manager, and Backup Manager within 1 click from the Dashboard.
+- **SC-002**: Navbar contains strictly 0 links to operational tools (Mapper, Search, Storage), containing only Tasks and Settings.
+- **SC-003**: "Run backup" action is successfully performed via the new Dashboard -> Backup route.

+
+## Implementation Strategy
+
+1. **Setup**: Create the new directory structure.
+2. **Dashboard & Navbar**: Quick wins to reshape the navigation.
+3. **Backup UI**: The core development effort. Connect to existing backend.
