feat: add devcontainer profiles for MCP development

- Split devcontainer config into base + profile structure
  - default: Standard Superset development (port 9001)
  - with-mcp: Superset + MCP service (ports 9001, 5008)
- Add MCP service to docker-compose-light.yml as optional profile
- Update start-superset.sh to conditionally start MCP when ENABLE_MCP=true
- Add MCP case to docker-bootstrap.sh for starting MCP service
- Preserve original devcontainer.json as .old for migration reference

This allows developers to choose their development environment:
- Use default profile for standard Superset development
- Use with-mcp profile for MCP/LLM agent development
- MCP service runs on port 5008 when enabled via profile

 For complete documentation on using GitHub Codespaces with Apache Superset, please see:
 
 **[Setting up a Development Environment - GitHub Codespaces](https://superset.apache.org/docs/contributing/development#github-codespaces-cloud-development)**
-
-## Pre-installed Development Environment
-
-When you create a new Codespace from this repository, it automatically:
-
-1. **Creates a Python virtual environment** using `uv venv`
-2. **Installs all development dependencies** via `uv pip install -r requirements/development.txt`
-3. **Sets up pre-commit hooks** with `pre-commit install`
-4. **Activates the virtual environment** automatically in all terminals
-
-The virtual environment is located at `/workspaces/{repository-name}/.venv` and is automatically activated through environment variables set in the devcontainer configuration.

+# Chart Metadata API Reference
+
+The Superset MCP service provides rich metadata alongside chart generation to enable better UI integration and user experiences.
+
+## Background & Design Philosophy
+
+Modern chart systems need to provide more than just visual output. Inspired by contemporary web standards and LLM integration patterns, this metadata system addresses several key needs:
+
+**Accessibility-First Design**: Following WCAG guidelines and `aria-*` attribute patterns, charts include semantic descriptions and accessibility metadata to ensure inclusive experiences.
+
+**Rich Context for AI Systems**: Similar to how platforms like social media generate rich previews (OpenGraph, Twitter Cards), charts provide semantic understanding beyond just visual representation - enabling AI agents to reason about and describe visualizations meaningfully.
+
+**Performance-Aware Integration**: Modern web APIs emphasize performance transparency (Core Web Vitals, etc.). Charts include execution metrics and optimization suggestions to help UIs make informed decisions about rendering and user feedback.
+
+**Capability-Driven UX**: Rather than requiring UIs to hardcode chart type behaviors, the system exposes what each chart can actually do - enabling dynamic, contextual interfaces that adapt to chart capabilities.
+
+## Overview
+
+When generating charts via `generate_chart`, the response includes structured metadata that helps UIs:
+- Present appropriate controls and interactions
+- Generate accessible descriptions
+- Optimize rendering performance
+- Guide user workflows
+
+## Metadata Types
+
+### ChartCapabilities
+
+Describes what interactions and features the chart supports.
+
+```python
+{
+  "supports_interaction": bool,      # User can interact (zoom, pan, hover)
+  "supports_real_time": bool,        # Chart can update with live data
+  "supports_drill_down": bool,       # Can navigate to more detailed views
+  "supports_export": bool,           # Can be exported to other formats
+  "optimal_formats": [               # Recommended preview formats
+    "url",           # Static image URL
+    "interactive",   # HTML with JavaScript controls
+    "ascii",         # Text-based representation
+    "vega_lite"      # Vega-Lite specification
+  ],
+  "data_types": [                    # Types of data visualized
+    "time_series",   # Time-based data
+    "categorical",   # Discrete categories
+    "metric"         # Numeric measurements
+  ]
+}
+```
+
+**UI Integration:**
+- Show/hide interaction controls based on `supports_interaction`
+- Enable real-time updates if `supports_real_time`
+- Display drill-down options for `supports_drill_down`
+- Choose optimal preview format from `optimal_formats`
+
+### ChartSemantics
+
+Provides semantic understanding of what the chart represents and reveals.
+
+```python
+{
+  "primary_insight": "Shows trends and changes over time",
+  "data_story": "This line chart analyzes sales, revenue over Q1-Q4",
+  "recommended_actions": [
+    "Review data patterns and trends",
+    "Consider filtering for more detail",
+    "Export chart for reporting"
+  ],
+  "anomalies": [],                   # Notable outliers (future enhancement)
+  "statistical_summary": {}         # Key statistics (future enhancement)
+}
+```
+
+**UI Integration:**
+- Display `primary_insight` as chart description
+- Use `data_story` for accessibility and tooltips
+- Show `recommended_actions` as suggested next steps
+- Highlight `anomalies` in the visualization
+
+### AccessibilityMetadata
+
+Information for creating inclusive, accessible chart experiences.
+
+```python
+{
+  "color_blind_safe": bool,          # Uses colorblind-friendly palette
+  "alt_text": "Chart showing Sales Data over time",
+  "high_contrast_available": bool    # High contrast version available
+}
+```
+
+**UI Integration:**
+- Use `alt_text` for screen readers
+- Show accessibility indicators if `color_blind_safe`
+- Offer high contrast mode if available
+
+### PerformanceMetadata
+
+Performance information for optimization and user feedback.
+
+```python
+{
+  "query_duration_ms": 1250,        # Time to generate chart data
+  "cache_status": "hit|miss|error", # Whether data came from cache
+  "optimization_suggestions": [      # Performance improvement tips
+    "Consider adding date filters to reduce data volume",
+    "Chart complexity may impact load time"
+  ]
+}
+```
+
+**UI Integration:**
+- Show loading indicators based on `query_duration_ms`
+- Display cache status for debugging
+- Present `optimization_suggestions` to users
+- Warn about slow queries
+
+## Example Response
+
+```json
+{
+  "chart": {
+    "id": 123,
+    "slice_name": "Sales Trends Q1-Q4",
+    "viz_type": "echarts_timeseries_line",
+    "url": "/explore/?slice_id=123"
+  },
+  "capabilities": {
+    "supports_interaction": true,
+    "supports_real_time": false,
+    "supports_drill_down": false,
+    "supports_export": true,
+    "optimal_formats": ["url", "interactive", "ascii"],
+    "data_types": ["time_series", "metric"]
+  },
+  "semantics": {
+    "primary_insight": "Shows trends and changes over time",
+    "data_story": "This line chart analyzes sales over Q1-Q4",
+    "recommended_actions": [
+      "Review seasonal patterns",
+      "Export for quarterly report"
+    ]
+  },
+  "accessibility": {
+    "color_blind_safe": true,
+    "alt_text": "Line chart showing sales trends from Q1 to Q4",
+    "high_contrast_available": false
+  },
+  "performance": {
+    "query_duration_ms": 450,
+    "cache_status": "miss",
+    "optimization_suggestions": []
+  }
+}
+```
+
+## Usage Examples
+
+### React Component Integration
+
+```jsx
+function ChartComponent({ chartData }) {
+  const { capabilities, semantics, accessibility, performance } = chartData;
+
+  return (
+    <div>
+      {/* Accessibility */}
+      <img
+        src={chartData.chart.url}
+        alt={accessibility.alt_text}
+        aria-describedby="chart-description"
+      />
+
+      {/* Semantic description */}
+      <p id="chart-description">{semantics.primary_insight}</p>
+
+      {/* Conditional controls based on capabilities */}
+      {capabilities.supports_interaction && (
+        <InteractiveControls />
+      )}
+
+      {capabilities.supports_export && (
+        <ExportButton />
+      )}
+
+      {/* Performance feedback */}
+      {performance.query_duration_ms > 2000 && (
+        <SlowQueryWarning suggestions={performance.optimization_suggestions} />
+      )}
+
+      {/* Recommended actions */}
+      <ActionSuggestions actions={semantics.recommended_actions} />
+    </div>
+  );
+}
+```
+
+## Chart Type Mapping
+
+Different chart types provide different capabilities:
+
+| Chart Type | Interaction | Real-time | Drill-down | Optimal Formats |
+|------------|------------|-----------|------------|-----------------|
+| `echarts_timeseries_line` | ✅ | ✅ | ❌ | url, interactive, ascii |
+| `echarts_timeseries_bar` | ✅ | ✅ | ❌ | url, interactive, ascii |
+| `table` | ❌ | ❌ | ✅ | url, table, ascii |
+| `pie` | ✅ | ❌ | ❌ | url, interactive |
+
+## Future Enhancements
+
+- **Statistical Summary**: Automatic calculation of mean, median, trends
+- **Anomaly Detection**: Identification of outliers and unusual patterns
+- **Smart Recommendations**: ML-powered suggestions for chart improvements
+- **Accessibility Scoring**: Automated accessibility compliance checking

 - **NO JavaScript files** - Convert to TypeScript (.ts/.tsx)
-- **Use @superset-ui/core** - Don't import Ant Design directly, prefer Ant Design component wrappers from @superset-ui/core/components
-- **Use antd theming tokens** - Prefer antd tokens over legacy theming tokens
-- **Avoid custom css and styles** - Follow antd best practices and avoid styling and custom CSS whenever possible

 ## Next
-- [33055](https://github.com/apache/superset/pull/33055): Upgrades Flask-AppBuilder to 5.0.0. The AUTH_OID authentication type has been deprecated and is no longer available as an option in Flask-AppBuilder. OpenID (OID) is considered a deprecated authentication protocol - if you are using AUTH_OID, you will need to migrate to an alternative authentication method such as OAuth, LDAP, or database authentication before upgrading.
-- [35062](https://github.com/apache/superset/pull/35062): Changed the function signature of `setupExtensions` to `setupCodeOverrides` with options as arguments.
-- [34871](https://github.com/apache/superset/pull/34871): Fixed Jest test hanging issue from Ant Design v5 upgrade. MessageChannel is now mocked in test environment to prevent rc-overflow from causing Jest to hang. Test environment only - no production impact.
-- [34782](https://github.com/apache/superset/pull/34782): Dataset exports now include the dataset ID in their file name (similar to charts and dashboards). If managing assets as code, make sure to rename existing dataset YAMLs to include the ID (and avoid duplicated files).
-- [34536](https://github.com/apache/superset/pull/34536): The `ENVIRONMENT_TAG_CONFIG` color values have changed to support only Ant Design semantic colors. Update your `superset_config.py`:
-  - Change `"error.base"` to just `"error"` after this PR
-  - Change any hex color values to one of: `"success"`, `"processing"`, `"error"`, `"warning"`, `"default"`
-  - Custom colors are no longer supported to maintain consistency with Ant Design components
-- [34561](https://github.com/apache/superset/pull/34561) Added tiled screenshot functionality for Playwright-based reports to handle large dashboards more efficiently. When enabled (default: `SCREENSHOT_TILED_ENABLED = True`), dashboards with 20+ charts or height exceeding 5000px will be captured using multiple viewport-sized tiles and combined into a single image. This improves report generation performance and reliability for large dashboards.
-Note: Pillow is now a required dependency (previously optional) to support image processing for tiled screenshots.
-`thumbnails` optional dependency is now deprecated and will be removed in the next major release (7.0).
 - [33084](https://github.com/apache/superset/pull/33084) The DISALLOWED_SQL_FUNCTIONS configuration now includes additional potentially sensitive database functions across PostgreSQL, MySQL, SQLite, MS SQL Server, and ClickHouse. Existing queries using these functions may now be blocked. Review your SQL Lab queries and dashboards if you encounter "disallowed function" errors after upgrading
 - [34235](https://github.com/apache/superset/pull/34235) CSV exports now use `utf-8-sig` encoding by default to include a UTF-8 BOM, improving compatibility with Excel.
 - [34258](https://github.com/apache/superset/pull/34258) changing the default in Dockerfile to INCLUDE_CHROMIUM="false" (from "true") in the past. This ensures the `lean` layer is lean by default, and people can opt-in to the `chromium` layer by setting the build arg `INCLUDE_CHROMIUM=true`. This is a breaking change for anyone using the `lean` layer, as it will no longer include Chromium by default.
@@ -43,7 +32,6 @@ Note: Pillow is now a required dependency (previously optional) to support image
 - [32317](https://github.com/apache/superset/pull/32317) The horizontal filter bar feature is now out of testing/beta development and its feature flag `HORIZONTAL_FILTER_BAR` has been removed.
 - [31590](https://github.com/apache/superset/pull/31590) Marks the begining of intricate work around supporting dynamic Theming, and breaks support for [THEME_OVERRIDES](https://github.com/apache/superset/blob/732de4ac7fae88e29b7f123b6cbb2d7cd411b0e4/superset/config.py#L671) in favor of a new theming system based on AntD V5. Likely this will be in disrepair until settling over the 5.x lifecycle.
 - [32432](https://github.com/apache/superset/pull/31260) Moves the List Roles FAB view to the frontend and requires `FAB_ADD_SECURITY_API` to be enabled in the configuration and `superset init` to be executed.
-- [34319](https://github.com/apache/superset/pull/34319) Drill to Detail and Drill By is now supported in Embedded mode, and also with the `DASHBOARD_RBAC` FF. If you don't want to expose these features in Embedded / `DASHBOARD_RBAC`, make sure the roles used for Embedded / `DASHBOARD_RBAC`don't have the required permissions to perform D2D actions.

+# This includes only essential services: database, Redis, and Superset app
 #
-# RUNNING SUPERSET:
-# 1. Start services: docker-compose -f docker-compose-light.yml up
-# 2. Access at: http://localhost:9001 (or NODE_PORT if specified)
-#
-# RUNNING MULTIPLE INSTANCES:
+# IMPORTANT: To run multiple instances in parallel:
 # - Use different project names: docker-compose -p project1 -f docker-compose-light.yml up
 # - Use different NODE_PORT values: NODE_PORT=9002 docker-compose -p project2 -f docker-compose-light.yml up
 # - Volumes are isolated by project name (e.g., project1_db_home_light, project2_db_home_light)
 # - Database name is intentionally different (superset_light) to prevent accidental cross-connections
 #
-# RUNNING TESTS WITH PYTEST:
-# Tests run in an isolated environment with a separate test database.
-# The pytest-runner service automatically creates and initializes the test database on first use.
+# MCP Service (Model Context Protocol):
+# - Optional service for LLM agent integration, available under 'mcp' profile
+# - To include MCP: docker-compose -f docker-compose-light.yml --profile mcp up
+# - MCP runs on port 5008 by default (customize with MCP_PORT=5009)
+# - Enable SQL debugging with MCP_SQL_DEBUG=true
 #
-# Basic usage:
-#   docker-compose -f docker-compose-light.yml run --rm pytest-runner pytest tests/unit_tests/
-#
-# Run specific test file:
-#   docker-compose -f docker-compose-light.yml run --rm pytest-runner pytest tests/unit_tests/test_foo.py
-#
-# Run with pytest options:
-#   docker-compose -f docker-compose-light.yml run --rm pytest-runner pytest -v -s -x tests/
-#
-# Force reload test database and run tests (when tests are failing due to bad state):
-#   docker-compose -f docker-compose-light.yml run --rm -e FORCE_RELOAD=true pytest-runner pytest tests/
-#
-# Run any command in test environment:
-#   docker-compose -f docker-compose-light.yml run --rm pytest-runner bash

-#
-# For parallel test execution with different projects:
-#   docker-compose -p project1 -f docker-compose-light.yml run --rm pytest-runner pytest tests/
-#
-# DEVELOPMENT TIPS:
-# - First test run takes ~20-30 seconds (database creation + initialization)
-# - Subsequent runs are fast (~2-3 seconds startup)
-# - Use FORCE_RELOAD=true when you need a clean test database
-# - Tests use SimpleCache instead of Redis (no Redis required)

docs/README.md

@@ -21,183 +21,3 @@ This is the public documentation site for Superset, built using
 [Docusaurus 3](https://docusaurus.io/). See
 [CONTRIBUTING.md](../CONTRIBUTING.md#documentation) for documentation on
 contributing to documentation.
-
-## Version Management
-
-The Superset documentation site uses Docusaurus versioning with three independent versioned sections:
-
-- **Main Documentation** (`/docs/`) - Core Superset documentation
-- **Developer Portal** (`/developer_portal/`) - Developer guides and tutorials  
-- **Component Playground** (`/components/`) - Interactive component examples (currently disabled)
-
-Each section maintains its own version history and can be versioned independently.
-
-### Creating a New Version
-
-To create a new version for any section, use the Docusaurus version command with the appropriate plugin ID or use our automated scripts:
-
-#### Using Automated Scripts (Required)
-
-**⚠️ Important:** Always use these custom commands instead of the native Docusaurus commands. These scripts ensure that both the Docusaurus versioning system AND the `versions-config.json` file are updated correctly.
-
-```bash
-# Main Documentation
-yarn version:add:docs 1.2.0
-
-# Developer Portal
-yarn version:add:developer_portal 1.2.0
-
-# Component Playground (when enabled)
-yarn version:add:components 1.2.0
-```
-
-**Do NOT use** the native Docusaurus commands directly (`yarn docusaurus docs:version`), as they will:
-- ❌ Create version files but NOT update `versions-config.json`
-- ❌ Cause versions to not appear in dropdown menus
-- ❌ Require manual fixes to synchronize the configuration
-
-### Managing Versions
-
-#### With Automated Scripts
-The automated scripts handle all configuration updates automatically. No manual editing required!
-
-#### Manual Configuration
-If creating versions manually, you'll need to:
-
-1. **Update `versions-config.json`** (or `docusaurus.config.ts` if not using dynamic config):
-   - Add version to `onlyIncludeVersions` array
-   - Add version metadata to `versions` object
-   - Update `lastVersion` if needed
-
-2. **Files Created by Versioning**:
-   When a new version is created, Docusaurus generates:
-   - **Versioned docs folder**: `[section]_versioned_docs/version-X.X.X/`
-   - **Versioned sidebars**: `[section]_versioned_sidebars/version-X.X.X-sidebars.json`
-   - **Versions list**: `[section]_versions.json`
-
-   Note: For main docs, the prefix is omitted (e.g., `versioned_docs/` instead of `docs_versioned_docs/`)
-
-3. **Important**: After adding a version, restart the development server to see changes:
-   ```bash
-   yarn stop
-   yarn start
-   ```
-
-### Removing a Version
-
-#### Using Automated Scripts (Recommended)
-```bash
-# Main Documentation
-yarn version:remove:docs 1.0.0
-
-# Developer Portal
-yarn version:remove:developer_portal 1.0.0
-
-# Component Playground
-yarn version:remove:components 1.0.0
-```
-
-#### Manual Removal
-To manually remove a version:
-
-1. **Delete the version folder** from the appropriate location:
-   - Main docs: `versioned_docs/version-X.X.X/` (no prefix for main)
-   - Developer Portal: `developer_portal_versioned_docs/version-X.X.X/`
-   - Components: `components_versioned_docs/version-X.X.X/`
-
-2. **Delete the version metadata file**:
-   - Main docs: `versioned_sidebars/version-X.X.X-sidebars.json` (no prefix)
-   - Developer Portal: `developer_portal_versioned_sidebars/version-X.X.X-sidebars.json`
-   - Components: `components_versioned_sidebars/version-X.X.X-sidebars.json`
-
-3. **Update the versions list file**:
-   - Main docs: `versions.json`
-   - Developer Portal: `developer_portal_versions.json`
-   - Components: `components_versions.json`
-
-4. **Update configuration**:
-   - If using dynamic config: Update `versions-config.json`
-   - If using static config: Update `docusaurus.config.ts`
-
-5. **Restart the server** to see changes
-
-### Version Configuration Examples
-
-#### Main Documentation (default plugin)
-```typescript
-docs: {
-  includeCurrentVersion: true,
-  lastVersion: 'current',  // Makes /docs/ show Next version
-  onlyIncludeVersions: ['current', '1.1.0', '1.0.0'],
-  versions: {
-    current: {
-      label: 'Next',
-      path: '',  // Empty path for default routing
-      banner: 'unreleased',
-    },
-    '1.1.0': {
-      label: '1.1.0',
-      path: '1.1.0',
-      banner: 'none',
-    },
-  },
-}
-```
-
-#### Developer Portal & Components (custom plugins)
-```typescript
-{
-  id: 'developer_portal',
-  path: 'developer_portal',
-  routeBasePath: 'developer_portal',
-  includeCurrentVersion: true,
-  lastVersion: '1.1.0',  // Default version
-  onlyIncludeVersions: ['current', '1.1.0', '1.0.0'],
-  versions: {
-    current: {
-      label: 'Next',
-      path: 'next',
-      banner: 'unreleased',
-    },
-    '1.1.0': {
-      label: '1.1.0',
-      path: '1.1.0',
-      banner: 'none',
-    },
-  },
-}
-```
-
-### Best Practices
-
-1. **Version naming**: Use semantic versioning (e.g., 1.0.0, 1.1.0, 2.0.0)
-2. **Version banners**: Use `'unreleased'` for development versions, `'none'` for stable releases
-3. **Limit displayed versions**: Use `onlyIncludeVersions` to show only relevant versions
-4. **Test locally**: Always test version changes locally before deploying
-5. **Independent versioning**: Each section can have different version numbers and release cycles
-
-### Troubleshooting
-
-#### Version Not Showing After Creation
-
-If you accidentally used `yarn docusaurus docs:version` instead of `yarn version:add`:
-1. **Problem**: The version files were created but `versions-config.json` wasn't updated
-2. **Solution**: Either:
-   - Revert the changes: `git restore versions.json && rm -rf versioned_docs/ versioned_sidebars/`
-   - Then use the correct command: `yarn version:add:docs <version>`
-
-For other issues:
-- **Restart the server**: Changes to version configuration require a server restart
-- **Check config file**: Ensure `versions-config.json` includes the new version
-- **Verify files exist**: Check that versioned docs folder was created
-
-#### Broken Links in Versioned Documentation
-When creating a new version, links in the documentation are preserved as-is. Common issues:
-- **Cross-section links**: Links between sections (e.g., from developer_portal to docs) need to be version-aware
-- **Absolute vs relative paths**: Use relative paths within the same section
-- **Version-specific URLs**: Update hardcoded URLs to use version variables
-
-To fix broken links:
-1. Use `type: 'doc'` with `docId` for version-aware navigation in navbar
-2. Use relative paths within the same documentation section
-3. Test all versions after creation to identify broken links

-| `showGrid` | `boolean` | `true` | Whether to show grid lines |
-| `labelPosition` | `string` | `'top'` | Position of bar labels: 'top', 'middle', 'bottom' |
-
-## Examples
-
-### Basic Bar Chart
-
-```jsx
-import { BarChart } from '@superset-ui/chart-components';
-
-const data = [
-  { category: 'A', value: 10 },
-  { category: 'B', value: 20 },
-  { category: 'C', value: 15 },
-  { category: 'D', value: 25 },
-];
-
-function Example() {
-  return (
-    <BarChart
-      data={data}
-      width={800}
-      height={400}
-      xField="category"
-      yField="value"
-      colorScheme="supersetColors"
-    />
-  );
-}
-```
-
-### Grouped Bar Chart
-
-```jsx
-import { BarChart } from '@superset-ui/chart-components';
-
-const data = [
-  { category: 'A', group: 'Group 1', value: 10 },
-  { category: 'A', group: 'Group 2', value: 15 },
-  { category: 'B', group: 'Group 1', value: 20 },
-  { category: 'B', group: 'Group 2', value: 25 },
-  { category: 'C', group: 'Group 1', value: 15 },
-  { category: 'C', group: 'Group 2', value: 10 },
-];
-
-function Example() {
-  return (
-    <BarChart
-      data={data}
-      width={800}
-      height={400}
-      xField="category"
-      yField="value"
-      colorField="group"
-      colorScheme="supersetColors"
-    />
-  );
-}
-```
-
-## Best Practices
-
-- Use bar charts when comparing quantities across categories
-- Sort bars by value for better readability, unless there's a natural order to the categories
-- Use consistent colors for the same categories across different charts
-- Consider using horizontal bar charts when category labels are long

-# Superset Component Library
-
-Welcome to the Apache Superset Component Library documentation. This section provides comprehensive documentation for all the UI components, chart components, and layout components used in Superset.
-
-## What is the Component Library?
-
-The Component Library is a collection of reusable UI components that are used to build the Superset user interface. These components are designed to be consistent, accessible, and easy to use.
-
-## Component Categories
-
-The Component Library is organized into the following categories:
-
-### UI Components
-
-Basic UI components like buttons, inputs, dropdowns, and other form elements.
-
-### Chart Components
-
-Visualization components used to render different types of charts and graphs.
-
-### Layout Components
-
-Components used for page layout, such as containers, grids, and navigation elements.
-
-## Versioning
-
-The Component Library documentation follows its own versioning scheme, independent from the main Superset documentation. This allows us to update the component documentation as the components evolve, without affecting the main documentation.
-
-## Getting Started
-
-Browse the sidebar to explore the different components available in the library. Each component documentation includes:
-
-- Component description and purpose
-- Props and configuration options
-- Usage examples
-- Best practices

-## Examples
-
-### Basic Grid
-
-```jsx
-import { Grid, Row, Col } from '@superset-ui/core';
-
-function Example() {
-  return (
-    <Grid>
-      <Row gutter={16}>
-        <Col span={8}>
-          <div>Column 1</div>
-        </Col>
-        <Col span={8}>
-          <div>Column 2</div>
-        </Col>
-        <Col span={8}>
-          <div>Column 3</div>
-        </Col>
-      </Row>
-    </Grid>
-  );
-}
-```
-
-### Responsive Grid
-
-```jsx
-import { Grid, Row, Col } from '@superset-ui/core';
-
-function Example() {
-  return (
-    <Grid>
-      <Row gutter={[16, 24]}>
-        <Col xs={24} sm={12} md={8} lg={6}>
-          <div>Responsive Column 1</div>
-        </Col>
-        <Col xs={24} sm={12} md={8} lg={6}>
-          <div>Responsive Column 2</div>
-        </Col>
-        <Col xs={24} sm={12} md={8} lg={6}>
-          <div>Responsive Column 3</div>
-        </Col>
-        <Col xs={24} sm={12} md={8} lg={6}>
-          <div>Responsive Column 4</div>
-        </Col>
-      </Row>
-    </Grid>
-  );
-}
-```
-
-## Best Practices
-
-- Use the Grid system for complex layouts that need to be responsive
-- Specify column widths for different screen sizes to ensure proper responsive behavior
-- Use gutters to create appropriate spacing between grid items
-- Keep the grid structure consistent throughout your application
-- Consider using the grid system for dashboard layouts to ensure consistent spacing and alignment

-      name: 'disabled',
-      label: 'Disabled',
-      type: 'boolean'
-    }
-  ]}
-/>
-
-## Props
-
-| Prop | Type | Default | Description |
-|------|------|---------|-------------|
-| `buttonStyle` | `'primary' \| 'secondary' \| 'tertiary' \| 'success' \| 'warning' \| 'danger' \| 'default' \| 'link' \| 'dashed'` | `'default'` | Button style |
-| `buttonSize` | `'default' \| 'small' \| 'xsmall'` | `'default'` | Button size |
-| `disabled` | `boolean` | `false` | Whether the button is disabled |
-| `cta` | `boolean` | `false` | Whether the button is a call-to-action button |
-| `tooltip` | `ReactNode` | - | Tooltip content |
-| `placement` | `TooltipProps['placement']` | - | Tooltip placement |
-| `onClick` | `function` | - | Callback when button is clicked |
-| `href` | `string` | - | Turns button into an anchor link |
-| `target` | `string` | - | Target attribute for anchor links |
-
-## Usage
-
-```jsx
-import Button from 'src/components/Button';
-
-function MyComponent() {
-  return (
-    <Button
-      buttonStyle="primary"
-      onClick={() => console.log('Button clicked')}
-    >
-      Click Me
-    </Button>
-  );
-}
-```
-
-## Button Styles
-
-Superset provides a variety of button styles for different purposes:
-
-- **Primary**: Used for primary actions
-- **Secondary**: Used for secondary actions
-- **Tertiary**: Used for less important actions
-- **Success**: Used for successful or confirming actions
-- **Warning**: Used for actions that require caution
-- **Danger**: Used for destructive actions
-- **Link**: Used for navigation
-- **Dashed**: Used for adding new items or features
-
-## Button Sizes
-
-Buttons come in three sizes:
-
-- **Default**: Standard size for most use cases
-- **Small**: Compact size for tight spaces
-- **XSmall**: Extra small size for very limited spaces
-
-## Best Practices
-
-- Use primary buttons for the main action in a form or page
-- Use secondary buttons for alternative actions
-- Use danger buttons for destructive actions
-- Limit the number of primary buttons on a page to avoid confusion
-- Use consistent button styles throughout your application
-- Add tooltips to buttons when their purpose might not be immediately clear

-storage.workspace.set(key: string, value: any): Promise<void>
-storage.workspace.get(key: string): Promise<any>
-storage.workspace.remove(key: string): Promise<void>
-```
-
-## Network API
-
-Utilities for making API calls to Superset.
-
-### fetch
-
-Enhanced fetch with CSRF token handling.
-
-```typescript
-network.fetch(url: string, options?: RequestInit): Promise<Response>
-```
-
-### API Client
-
-Type-safe API client for Superset endpoints.
-
-```typescript

-network.api.sqlLab.execute(
-  databaseId: number,
-  query: string
-): Promise<QueryResult>
-
-// Get datasets
-network.api.datasets.list(): Promise<Dataset[]>
-```
-
-## Utility Functions
-
-### Formatting
-
-```typescript
-// Format numbers
-utils.formatNumber(value: number, format?: string): string
-
-// Format dates
-utils.formatDate(date: Date, format?: string): string
-
-// Format SQL
-utils.formatSQL(sql: string): string
-```
-
-### Validation
-
-```typescript
-// Validate SQL syntax
-utils.validateSQL(sql: string): ValidationResult
-
-// Check if valid database ID
-utils.isValidDatabaseId(id: any): boolean
-```
-
-## TypeScript Types
-
-Import common types for type safety:
-
-```typescript
-import type {
-  Database,
-  Dataset,
-  Chart,
-  Dashboard,
-  Query,
-  QueryResult,
-  Tab,
-  Panel,
-  User,
-  Role,
-  Permission,
-  ExtensionContext,
-  Disposable,
-  Event,
-  // ... more types
-} from '@apache-superset/core';
-```
-
-## Extension Context
-
-The context object passed to your extension's `activate` function:
-
-```typescript
-interface ExtensionContext {
-  // Subscription management
-  subscriptions: Disposable[];
-
-  // Extension metadata
-  extensionId: string;
-  extensionPath: string;
-
-  // API namespaces
-  core: CoreAPI;
-  commands: CommandsAPI;
-  sqlLab: SqlLabAPI;
-  authentication: AuthenticationAPI;
-  extensions: ExtensionsAPI;
-  storage: StorageAPI;
-  network: NetworkAPI;
-  utils: UtilsAPI;
-
-  // Logging
-  logger: Logger;
-}
-```
-
-## Event Handling
-
-Events follow the VS Code pattern with subscribe/dispose:
-
-```typescript
-// Subscribe to event
-const disposable = sqlLab.onDidQueryRun((result) => {
-  // Handle event
-});
-
-// Dispose when done
-disposable.dispose();
-
-// Or add to context for automatic cleanup
-context.subscriptions.push(disposable);
-```
-
-## Best Practices
-
-1. **Always dispose subscriptions** to prevent memory leaks
-2. **Use TypeScript** for better IDE support and type safety
-3. **Handle errors gracefully** with try-catch blocks
-4. **Check permissions** before sensitive operations
-5. **Use provided UI components** for consistency
-6. **Cache API responses** when appropriate
-7. **Validate user input** before processing
-
-## Version Compatibility
-
-The frontend API follows semantic versioning:
-
-- **Major version**: Breaking changes
-- **Minor version**: New features, backward compatible
-- **Patch version**: Bug fixes
-
-Check compatibility in your `extension.json`:
-
-```json
-{
-  "engines": {
-    "@apache-superset/core": "^1.0.0"
-  }
-}
-```

-# Extension Architecture Overview
-
-The Superset extension architecture is designed to be modular, secure, and performant. This document provides a comprehensive overview of how extensions work and interact with the Superset host application.
-
-## Core Principles
-
-### 1. Lean Core
-Superset's core remains minimal, with features delegated to extensions wherever possible. Built-in features use the same APIs as external extensions, ensuring API quality through dogfooding.
-
-### 2. Explicit Contribution Points
-All extension points are clearly defined and documented. Extensions declare their capabilities in metadata files, enabling predictable lifecycle management.
-
-### 3. Versioned APIs
-Public interfaces follow semantic versioning, ensuring backward compatibility and safe evolution of the platform.
-
-### 4. Lazy Loading
-Extensions load only when needed, minimizing performance impact and resource consumption.
-
-### 5. Composability
-Architecture patterns and APIs are reusable across different Superset modules, promoting consistency.
-
-### 6. Community-Driven
-The system evolves based on real-world feedback, with new extension points added as needs emerge.
-
-## System Architecture

-    API --> BackendCore
-    Loader --> Manager
-    Manager --> Bundle
-    Frontend --> FrontendCore
-    Backend --> BackendCore
-    CLI --> Bundle
-```
-
-## Key Components
-
-### Host Application
-
-The Superset host application provides:
-
-- **Extension APIs**: Well-defined interfaces for extensions to interact with Superset
-- **Extension Manager**: Handles lifecycle, activation, and deactivation
-- **Module Loader**: Dynamically loads extension code using Webpack Module Federation
-- **Security Context**: Manages permissions and sandboxing for extensions
-
-### Core Packages
-
-#### @apache-superset/core (Frontend)
-- Shared UI components and utilities
-- TypeScript type definitions
-- Frontend API implementations
-- Event system and command registry
-
-#### apache-superset-core (Backend)
-- Python base classes and utilities
-- Database access APIs
-- Security and permission helpers
-- REST API registration
-
-#### apache-superset-extensions-cli
-- Project scaffolding
-- Build and bundling tools
-- Development server
-- Package management
-
-### Extension Structure
-
-Each extension consists of:
-
-- **Metadata** (`extension.json`): Declares capabilities and requirements
-- **Frontend**: React components and TypeScript code
-- **Backend**: Python modules and API endpoints
-- **Assets**: Styles, images, and other resources
-- **Bundle** (`.supx`): Packaged distribution format
-
-## Module Federation
-
-Extensions use Webpack Module Federation for dynamic loading:
-
-```javascript
-// Extension webpack.config.js
-new ModuleFederationPlugin({
-  name: 'my_extension',
-  filename: 'remoteEntry.[contenthash].js',
-  exposes: {
-    './index': './src/index.tsx',
-  },
-  externals: {
-    '@apache-superset/core': 'superset',
-  },
-  shared: {
-    react: { singleton: true },
-    'react-dom': { singleton: true },
-  }
-})
-```
-
-This allows:
-- **Independent builds**: Extensions compile separately from Superset
-- **Shared dependencies**: Common libraries like React aren't duplicated
-- **Dynamic loading**: Extensions load at runtime without rebuilding Superset
-- **Version compatibility**: Extensions declare compatible core versions
-
-## Extension Lifecycle
-
-### 1. Registration
-```typescript
-// Extension registered with host
-extensionManager.register({
-  name: 'my-extension',
-  version: '1.0.0',
-  manifest: manifestData
-});
-```
-
-### 2. Activation
-```typescript
-// activate() called when extension loads
-export function activate(context: ExtensionContext) {
-  // Register contributions
-  const disposables = [];
-
-  // Add panel
-  disposables.push(
-    context.core.registerView('my-panel', MyPanel)
-  );
-
-  // Register command
-  disposables.push(
-    context.commands.registerCommand('my-command', {
-      execute: () => { /* ... */ }
-    })
-  );
-
-  // Store for cleanup
-  context.subscriptions.push(...disposables);
-}
-```
-
-### 3. Runtime
-- Extension responds to events
-- Provides UI components when requested
-- Executes commands when triggered
-- Accesses APIs as needed
-
-### 4. Deactivation
-```typescript
-// Automatic cleanup of registered items
-export function deactivate() {
-  // context.subscriptions automatically disposed
-  // Additional cleanup if needed
-}
-```
-
-## Contribution Types
-
-### Views
-Extensions can add panels and UI components:
-
-```json
-{
-  "views": {
-    "sqllab.panels": [{
-      "id": "my-panel",
-      "name": "My Panel",
-      "icon": "ToolOutlined"
-    }]
-  }
-}
-```
-
-### Commands
-Define executable actions:
-
-```json
-{
-  "commands": [{
-    "command": "my-extension.run",
-    "title": "Run Analysis",
-    "icon": "PlayCircleOutlined"
-  }]
-}
-```
-
-### Menus
-Add items to existing menus:
-
-```json
-{
-  "menus": {
-    "sqllab.editor": {
-      "primary": [{
-        "command": "my-extension.run",
-        "when": "editorHasSelection"
-      }]
-    }
-  }
-}
-```
-
-### API Endpoints
-Register backend REST endpoints:
-
-```python
-from superset_core.api import rest_api
-
-@rest_api.route('/my-endpoint')
-def my_endpoint():
-    return {'data': 'value'}
-```
-
-## Security Model
-
-### Permissions
-- Extensions run with user's permissions
-- No elevation of privileges
-- Access controlled by Superset's RBAC
-
-### Sandboxing
-- Frontend code runs in browser context
-- Backend code runs in Python process
-- Future: Optional sandboxed execution
-
-### Validation
-- Manifest validation on upload
-- Signature verification (future)
-- Dependency scanning
-
-## Performance Considerations
-
-### Lazy Loading
-- Extensions load only when features are accessed
-- Code splitting for large extensions
-- Cached after first load
-
-### Bundle Optimization
-- Tree shaking removes unused code
-- Minification reduces size
-- Compression for network transfer
-
-### Resource Management
-- Automatic cleanup on deactivation
-- Memory leak prevention
-- Event listener management
-
-## Development vs Production
-
-### Development Mode
-```python
-# superset_config.py
-ENABLE_EXTENSIONS = True
-LOCAL_EXTENSIONS = ['/path/to/extension']
-```
-- Hot reloading
-- Source maps
-- Debug logging
-
-### Production Mode
-- Optimized bundles
-- Cached assets
-- Performance monitoring
-
-## Future Enhancements
-
-### Planned Features
-- Enhanced sandboxing
-- Extension marketplace
-- Inter-extension communication
-- Theme contributions
-- Chart type extensions
-
-### API Expansion
-- Dashboard extensions
-- Database connector API
-- Security provider interface
-- Workflow automation
-
-## Best Practices
-
-### Do's
-- ✅ Use TypeScript for type safety
-- ✅ Follow semantic versioning
-- ✅ Handle errors gracefully
-- ✅ Clean up resources properly
-- ✅ Document your extension
-
-### Don'ts
-- ❌ Access private APIs
-- ❌ Modify global state directly
-- ❌ Block the main thread
-- ❌ Store sensitive data insecurely
-- ❌ Assume API stability in 0.x versions

-## Configuration
-
-### Project Configuration
-
-The CLI reads configuration from multiple sources:
-
-1. **extension.json** - Extension metadata
-2. **package.json** - Frontend dependencies
-3. **pyproject.toml** - Backend configuration
-4. **.extensionrc** - CLI-specific settings
-
-### .extensionrc Example
-
-```json
-{
-  "dev": {
-    "port": 9001,
-    "host": "localhost",
-    "autoReload": true
-  },
-  "build": {
-    "mode": "production",
-    "sourceMaps": false,
-    "optimization": true
-  },
-  "test": {
-    "coverage": true,
-    "threshold": {
-      "statements": 80,
-      "branches": 70,
-      "functions": 80,
-      "lines": 80
-    }
-  }
-}
-```
-
-## Templates
-
-### Available Templates
-
-- **basic**: Simple extension with frontend only
-- **full-stack**: Frontend and backend components
-- **sql-panel**: SQL Lab panel extension
-- **api-only**: Backend API extension
-- **chart-plugin**: Custom chart visualization
-
-### Using Templates
-
-```bash
-# Use specific template
-superset-extensions init my-chart --template chart-plugin
-
-# List available templates
-superset-extensions init --list-templates
-```
-
-### Custom Templates
-
-Create custom templates in `~/.superset-extensions/templates/`:
-
-```
-~/.superset-extensions/templates/
-└── my-template/
-    ├── template.json
-    └── files/
-        └── ... template files ...
-```
-
-## Development Workflow
-
-### 1. Create Extension
-
-```bash
-superset-extensions init awesome-feature
-cd awesome-feature
-```
-
-### 2. Install Dependencies
-
-```bash
-# Frontend
-cd frontend && npm install
-
-# Backend (if applicable)
-cd ../backend && pip install -r requirements.txt
-```
-
-### 3. Configure Superset
-
-```python
-# superset_config.py
-ENABLE_EXTENSIONS = True
-LOCAL_EXTENSIONS = [
-    "/path/to/awesome-feature"
-]
-```
-
-### 4. Start Development
-
-```bash
-# Terminal 1: Extension dev server
-superset-extensions dev
-
-# Terminal 2: Superset
-superset run -p 8088 --reload
-```
-
-### 5. Test Changes
-
-Make changes to your code and see them reflected immediately in Superset.
-
-### 6. Build and Package
-
-```bash
-# Validate
-superset-extensions validate
-
-# Test
-superset-extensions test
-
-# Build
-superset-extensions build --mode production
-
-# Bundle
-superset-extensions bundle
-```
-
-### 7. Deploy
-
-Upload the `.supx` file to your Superset instance.
-
-## Environment Variables
-
-The CLI respects these environment variables:
-
-- `SUPERSET_EXTENSIONS_DEV_PORT`: Development server port
-- `SUPERSET_EXTENSIONS_DEV_HOST`: Development server host
-- `SUPERSET_BASE_URL`: Superset instance URL
-- `NODE_ENV`: Node environment (development/production)
-- `PYTHONPATH`: Python module search path
-
-## Troubleshooting
-
-### Common Issues
-
-#### Port Already in Use
-
-```bash
-# Use different port
-superset-extensions dev --port 9002
-```
-
-#### Module Federation Errors
-
-```bash
-# Rebuild with clean cache
-rm -rf dist/ node_modules/.cache
-superset-extensions build
-```
-
-#### Python Import Errors
-
-```bash
-# Ensure virtual environment is activated
-source venv/bin/activate
-superset-extensions dev
-```
-
-### Debug Mode
-
-Enable verbose output for troubleshooting:
-
-```bash
-# Verbose output
-superset-extensions dev --verbose
-
-# Debug webpack
-DEBUG=webpack:* superset-extensions build
-```
-
-## Best Practices
-
-1. **Version Control**: Commit `extension.json` but not `dist/`
-2. **Dependencies**: Pin versions in package.json
-3. **Testing**: Write tests for critical functionality
-4. **Documentation**: Keep README.md updated
-5. **Validation**: Run validate before bundling
-6. **Semantic Versioning**: Follow semver for releases
-
-## Advanced Usage
-
-### Custom Webpack Configuration
-
-Extend the default webpack config:
-
-```javascript
-// webpack.config.js
-const baseConfig = require('./webpack.base.config');
-
-module.exports = {
-  ...baseConfig,
-  // Custom modifications
-  resolve: {
-    ...baseConfig.resolve,
-    alias: {
-      '@': path.resolve(__dirname, 'src'),
-    },
-  },
-};
-```
-
-### CI/CD Integration
-
-```yaml
-# .github/workflows/extension.yml

-  it('should extract tables from SQL', () => {
-    const sql = 'SELECT * FROM users JOIN orders ON users.id = orders.user_id';
-    const tables = extractTables(sql);
-
-    expect(tables).toEqual([
-      { schema: 'public', table: 'users' },
-      { schema: 'public', table: 'orders' },

-# Getting Started with Extensions
-
-This guide will walk you through creating, developing, and deploying your first Superset extension.
-
-## Prerequisites
-
-Before you begin, make sure you have:
-
-- **Node.js 16+** and npm/yarn installed
-- **Python 3.9+** and pip installed  
-- **Superset** running locally or access to a Superset instance
-- **Git** for version control
-- Basic knowledge of React and TypeScript
-
-## Quick Start
-
-### 1. Install the CLI
-
-First, install the Superset Extensions CLI globally:
-
-```bash
-pip install apache-superset-extensions-cli
-```
-
-### 2. Create Your First Extension
-
-Use the CLI to scaffold a new extension project:
-
-```bash
-superset-extensions init my-first-extension
-cd my-first-extension
-```
-
-This creates the following structure:
-
-```
-my-first-extension/
-├── extension.json          # Extension metadata
-├── frontend/              # Frontend code
-│   ├── src/
-│   │   └── index.tsx     # Main entry point
-│   ├── package.json
-│   └── webpack.config.js
-├── backend/              # Backend code (optional)
-│   ├── src/
-│   └── requirements.txt
-└── README.md
-```
-
-### 3. Configure Your Extension
-
-Edit `extension.json` to define your extension's capabilities:
-
-```json
-{
-  "name": "my-first-extension",
-  "version": "1.0.0",

-### 4. Develop Your Extension
-
-Edit `frontend/src/index.tsx` to implement your extension:
-
-```typescript
-import React from 'react';
-import { ExtensionContext } from '@apache-superset/core';
-
-export function activate(context: ExtensionContext) {
-  // Register your panel component
-  const panel = context.core.registerView('my-extension.main', () => (
-    <div style={{ padding: 20 }}>
-      <h2>Hello from My Extension!</h2>
-      <p>This is my first Superset extension.</p>
-    </div>
-  ));
-
-  // Clean up on deactivation
-  context.subscriptions.push(panel);
-}
-
-export function deactivate() {
-  // Cleanup code if needed
-}
-```
-
-### 5. Test Locally
-
-Enable development mode in your Superset configuration:
-
-```python
-# superset_config.py
-ENABLE_EXTENSIONS = True
-LOCAL_EXTENSIONS = [
-    "/path/to/my-first-extension"
-]
-```
-
-Run the development server:
-
-```bash
-# In your extension directory
-superset-extensions dev
-
-# In a separate terminal, start Superset
-superset run -p 8088 --with-threads --reload
-```
-
-Your extension will now appear in SQL Lab!
-
-### 6. Build and Package
-
-When ready to distribute your extension:
-
-```bash
-superset-extensions build
-superset-extensions bundle
-```
-
-This creates a `my-first-extension-1.0.0.supx` file that can be uploaded to any Superset instance.
-
-### 7. Deploy
-
-Upload your extension via the Superset UI or API:
-
-```bash
-curl -X POST http://localhost:8088/api/v1/extensions/import/ \
-  -H "Authorization: Bearer YOUR_TOKEN" \
-  -F "file=@my-first-extension-1.0.0.supx"
-```

-## Common Patterns
-
-### Adding a SQL Lab Panel
-
-```typescript
-const panel = context.core.registerView('my-extension.panel', () => (
-  <MyPanelComponent />
-));
-```
-
-### Registering Commands
-
-```typescript
-const command = context.commands.registerCommand('my-extension.run', {
-  title: 'Run My Command',
-  execute: () => {
-    // Command logic
-  }
-});
-```
-
-### Listening to Events
-
-```typescript
-const listener = context.sqlLab.onDidQueryRun((query) => {
-  console.log('Query executed:', query);
-});
-```
-
-### Adding Menu Items
-
-```json
-{
-  "menus": {
-    "sqllab.editor": {
-      "primary": [{
-        "command": "my-extension.run",
-        "when": "editorHasSelection"
-      }]
-    }
-  }
-}
-```
-
-## Troubleshooting
-
-### Extension Not Loading
-
-- Ensure `ENABLE_EXTENSIONS = True` in your config
-- Check the browser console for errors
-- Verify the extension path in `LOCAL_EXTENSIONS`
-
-### Module Not Found Errors
-
-- Run `npm install` in the frontend directory
-- Check that `@apache-superset/core` is properly externalized
-
-### Build Failures
-
-- Ensure all dependencies are installed
-- Check webpack.config.js for proper Module Federation setup
-- Verify extension.json is valid JSON
