fix(tests): update UTC and Pacific timezone test expectations for timezone-mock 1.4.0

The previous commit addressed Etc/GMT-2 timezone test expectations.
This commit updates the remaining failing tests for UTC and Etc/GMT+8
(Pacific) timezone cases in parseDttmToDate.test.ts to match the new
behavior of timezone-mock 1.4.0.

+## Developer Portal: Storybook-to-MDX Documentation
+
+The Developer Portal auto-generates MDX documentation from Storybook stories. **Stories are the single source of truth.**
+
+### Core Philosophy
+- **Fix issues in the STORY, not the generator** - When something doesn't render correctly, update the story file first
+- **Generator should be lightweight** - It extracts and passes through data; avoid special cases
+- **Stories define everything** - Props, controls, galleries, examples all come from story metadata
+
+### Story Requirements for Docs Generation
+- Use `export default { title: '...' }` (inline), not `const meta = ...; export default meta;`
+- Name interactive stories `Interactive${ComponentName}` (e.g., `InteractiveButton`)
+- Define `args` for default prop values
+- Define `argTypes` at the story level (not meta level) with control types and descriptions
+- Use `parameters.docs.gallery` for size×style variant grids
+- Use `parameters.docs.sampleChildren` for components that need children
+- Use `parameters.docs.liveExample` for custom live code blocks
+- Use `parameters.docs.staticProps` for complex object props that can't be parsed inline
+
+### Generator Location
+- Script: `docs/scripts/generate-superset-components.mjs`
+- Wrapper: `docs/src/components/StorybookWrapper.jsx`
+- Output: `docs/developer_portal/components/`
+

+### WebSocket config for GAQ with Docker
+
+[35896](https://github.com/apache/superset/pull/35896) and [37624](https://github.com/apache/superset/pull/37624) updated documentation on how to run and configure Superset with Docker. Specifically for the WebSocket configuration, a new `docker/superset-websocket/config.example.json` was added to the repo, so that users could copy it to create a `docker/superset-websocket/config.json` file. The existing `docker/superset-websocket/config.json` was removed and git-ignored, so if you're using GAQ / WebSocket make sure to:
+- Stash/backup your existing `config.json` file, to re-apply it after (will get git-ignored going forward)
+- Update the `volumes` configuration for the `superset-websocket` service in your `docker-compose.override.yml` file, to include the `docker/superset-websocket/config.json` file. For example:
+``` yaml
+services:
+  superset-websocket:
+    volumes:
+      - ./superset-websocket:/home/superset-websocket
+      - /home/superset-websocket/node_modules

+# Developer Portal Documentation Instructions
+
+## Core Principle: Stories Are the Single Source of Truth
+
+When working on the Storybook-to-MDX documentation system:
+
+**ALWAYS fix the story first. NEVER add workarounds to the generator.**
+
+## Why This Matters
+
+The generator (`scripts/generate-superset-components.mjs`) should be lightweight - it extracts data from stories and passes it through. When you add special cases to the generator:
+- It becomes harder to maintain
+- Stories diverge from their docs representation
+- Future stories need to know about generator quirks
+
+When you fix stories to match the expected patterns:
+- Stories work identically in Storybook and Docs
+- The generator stays simple and predictable
+- Patterns are consistent and learnable
+
+## Story Patterns for Docs Generation
+
+### Required Structure
+```tsx
+// Use inline export default (NOT const meta = ...; export default meta)
+export default {
+  title: 'Components/MyComponent',
+  component: MyComponent,
+};
+
+// Name interactive stories with Interactive prefix
+export const InteractiveMyComponent: Story = {
+  args: {
+    // Default prop values
+  },
+  argTypes: {
+    // Control definitions - MUST be at story level, not meta level
+    propName: {
+      control: { type: 'select' },
+      options: ['a', 'b', 'c'],
+      description: 'What this prop does',
+    },
+  },
+};
+```
+
+### For Components with Variants (size × style grids)
+```tsx
+const sizes = ['small', 'medium', 'large'];
+const variants = ['primary', 'secondary', 'danger'];
+
+InteractiveButton.parameters = {
+  docs: {
+    gallery: {
+      component: 'Button',
+      sizes,
+      styles: variants,
+      sizeProp: 'size',
+      styleProp: 'variant',
+    },
+  },
+};
+```
+
+### For Components Requiring Children
+```tsx
+InteractiveIconTooltip.parameters = {
+  docs: {
+    // Component descriptors with dot notation for nested components
+    sampleChildren: [{ component: 'Icons.InfoCircleOutlined', props: { iconSize: 'l' } }],
+  },
+};
+```
+
+### For Custom Live Code Examples
+```tsx
+InteractiveMyComponent.parameters = {
+  docs: {
+    liveExample: `function Demo() {
+  return <MyComponent prop="value">Content</MyComponent>;
+}`,
+  },
+};
+```
+
+### For Complex Props (objects, arrays)
+```tsx
+InteractiveMenu.parameters = {
+  docs: {
+    staticProps: {
+      items: [
+        { key: '1', label: 'Item 1' },
+        { key: '2', label: 'Item 2' },
+      ],
+    },
+  },
+};
+```
+
+## Common Issues and How to Fix Them (in the Story)
+
+| Issue | Wrong Approach | Right Approach |
+|-------|---------------|----------------|
+| Component not generated | Add pattern to generator | Change story to use inline `export default` |
+| Control shows as text instead of select | Add special case in generator | Add `argTypes` with `control: { type: 'select' }` |
+| Missing children/content | Modify StorybookWrapper | Add `parameters.docs.sampleChildren` |
+| Gallery not showing | Add to generator output | Add `parameters.docs.gallery` config |
+| Wrong live example | Hardcode in generator | Add `parameters.docs.liveExample` |
+
+## Files
+
+- **Generator**: `docs/scripts/generate-superset-components.mjs`
+- **Wrapper**: `docs/src/components/StorybookWrapper.jsx`

-# Extension Administrator Configuration
-
-This guide covers how to configure extension security for production deployments. As an administrator, you control which extensions can run and at what trust level.
-
-## Trust Configuration
-
-Configure extension trust in `superset_config.py`:
-
-```python
-EXTENSIONS_TRUST_CONFIG = {
-    # Extensions that can run with full privileges ('core' trust level)
-    "trusted_extensions": [
-        "official-parquet-export",
-        "enterprise-sso-plugin",
-    ],
-
-    # Allow any extension to run as 'core' without signature verification
-    # WARNING: NEVER enable in production - development use only!
-    "allow_unsigned_core": False,
-
-    # Default sandbox for extensions without explicit trust configuration
-    # Options: 'core', 'iframe', 'worker', 'wasm'
-    "default_trust_level": "iframe",
-
-    # Require valid signatures for extensions requesting 'core' trust
-    # Recommended for production deployments
-    "require_core_signatures": True,
-
-    # Public keys for verified publishers (file paths or PEM strings)
-    "trusted_signers": [
-        "/etc/superset/keys/apache-official.pub",
-        "/etc/superset/keys/enterprise-team.pub",
-    ],
-}
-```
-
-## Configuration Options
-
-### `trusted_extensions`
-
-A list of extension IDs that are allowed to run as `core` trust level without signature verification. Use this for extensions you've reviewed and trust completely.
-
-```python
-"trusted_extensions": [
-    "my-company-plugin",
-    "approved-community-extension",
-],
-```
-
-### `allow_unsigned_core`
-
-When `True`, allows any extension to run as `core` trust level regardless of signatures or trusted list. **Never enable this in production** - it's intended only for development environments.
-
-```python
-# Development only!
-"allow_unsigned_core": True,
-```
-
-### `default_trust_level`
-
-The trust level assigned to extensions that don't specify one in their manifest. The safest option is `iframe`, which provides browser-enforced isolation.
-
-| Level | Description |
-|-------|-------------|
-| `iframe` | Browser-sandboxed iframe with controlled API access (recommended default) |
-| `worker` | Web Worker sandbox for command-only extensions |
-| `wasm` | WASM sandbox with no DOM access (most restrictive) |
-| `core` | Full access to main context (not recommended as default) |
-
-```python
-"default_trust_level": "iframe",
-```
-
-### `require_core_signatures`
-
-When `True`, extensions requesting `core` trust level must have a valid signature from a trusted signer. Extensions without valid signatures are downgraded to `default_trust_level`.
-
-```python
-"require_core_signatures": True,
-```
-
-### `trusted_signers`
-
-A list of public keys authorized to sign extensions. Keys can be specified as file paths or inline PEM strings.
-
-```python
-"trusted_signers": [
-    # File path to public key
-    "/etc/superset/keys/publisher.pub",
-
-    # Inline PEM string
-    """-----BEGIN PUBLIC KEY-----
-MCowBQYDK2VwAyEA...
------END PUBLIC KEY-----""",
-],
-```
-
-## Signature Verification
-
-### How It Works
-
-1. Extension developers generate a signing keypair using the CLI
-2. They sign their extension's manifest during the build process
-3. The signed bundle includes `manifest.sig` alongside `manifest.json`
-4. When Superset loads the extension, it verifies the signature against `trusted_signers`
-5. If verification passes, the extension can run at its requested trust level
-
-### Configuring Trusted Signers
-
-1. Obtain the publisher's public key file (`.pub` extension)
-2. Place it in a secure location on your server (e.g., `/etc/superset/keys/`)
-3. Add the path to `trusted_signers` in your configuration
-
-```python
-EXTENSIONS_TRUST_CONFIG = {
-    "trusted_signers": [
-        "/etc/superset/keys/acme-corp.pub",
-    ],
-    "require_core_signatures": True,
-}
-```
-
-### Verifying a Key Fingerprint
-
-Before adding a public key to your trusted signers, verify its fingerprint with the publisher:
-
-```bash
-# On the publisher's machine
-superset-extensions generate-keys --output my-key.pem
-# Output: Fingerprint: MCowBQYDK2Vw...
-```
-
-Compare this fingerprint with what you receive to ensure authenticity.
-
-## Security Recommendations
-
-### Production Deployments
-
-1. **Set `require_core_signatures: True`** - Ensures core extensions are verified
-2. **Set `allow_unsigned_core: False`** - Never allow unsigned core extensions
-3. **Use `iframe` as default** - Provides strong browser isolation
-4. **Limit `trusted_extensions`** - Only add extensions you've thoroughly reviewed
-5. **Secure key storage** - Store public keys in protected directories
-
-### Development Environments
-
-For local development, you may relax some restrictions:
-
-```python
-# Development configuration
-EXTENSIONS_TRUST_CONFIG = {
-    "trusted_extensions": [],
-    "allow_unsigned_core": True,  # OK for development
-    "default_trust_level": "core",  # Easier debugging
-    "require_core_signatures": False,
-    "trusted_signers": [],
-}
-```
-
-## Extension Installation
-
-### From Trusted Sources
-
-1. Download the `.supx` bundle from a trusted source
-2. Verify any checksums or signatures provided by the publisher
-3. Place the bundle in your `EXTENSIONS_PATH` directory
-4. If the extension requires `core` trust, add it to `trusted_extensions` or configure signature verification
-
-### From Community Registry
-
-Extensions from the community registry should be treated as semi-trusted at best. Consider:
-
-1. Using `iframe` sandbox for community extensions
-2. Reviewing the extension's source code before installation
-3. Testing in a staging environment first
-
-## Monitoring Extensions
-
-### Logging
-
-Extension trust decisions are logged at the INFO level:
-
-```
-INFO: Extension my-extension granted core trust (trusted + valid signature)
-WARNING: Extension unknown-ext trust downgraded from core to iframe: Extension not in trusted list
-```
-
-Review these logs to monitor extension behavior and identify potential issues.
-
-### Trust Downgrades
-
-If an extension's trust is downgraded, you'll see a warning in the logs. Common reasons:
-
-| Reason | Meaning |
-|--------|---------|
-| "Extension not in trusted list" | Extension requests core but isn't in `trusted_extensions` |
-| "Core trust requires a valid signature" | `require_core_signatures` is enabled but signature is missing |
-| "Signature verification failed" | Signature doesn't match any trusted signer |
-
-## Troubleshooting
-
-### Extension Not Loading as Core
-
-1. Check if the extension ID is in `trusted_extensions`
-2. If using signatures, verify the public key is in `trusted_signers`
-3. Check logs for trust downgrade messages
-4. Verify the extension bundle contains `manifest.sig`
-
-### Signature Verification Failing
-
-1. Ensure the public key file is readable by the Superset process
-2. Verify the key is in PEM format with correct Ed25519 type
-3. Check that the manifest wasn't modified after signing
-4. Confirm the signature was created with the matching private key
-
-### Permission Denied Errors
-
-Sandboxed extensions may encounter permission errors if:
-
-1. The extension's declared permissions don't match its API calls
-2. The sandbox is blocking access correctly (working as intended)
-3. The extension was downgraded to a more restrictive sandbox
-
-Check the extension's `sandbox.permissions` configuration against its actual needs.

-# Extension Components
-
-These UI components are available to Superset extension developers through the `@apache-superset/core/ui` package. They provide a consistent look and feel with the rest of Superset and are designed to be used in extension panels, views, and other UI elements.
-
-## Available Components
-
-- [Alert](./alert)
-
-## Usage
-
-All components are exported from the `@apache-superset/core/ui` package:
-
-```tsx
-import { Alert } from '@apache-superset/core/ui';
-
-export function MyExtensionPanel() {
-  return (
-    <Alert type="info">
-      Welcome to my extension!
-    </Alert>
-  );
-}
-```
-
-## Adding New Components
-
-Components in `@apache-superset/core/ui` are automatically documented here. To add a new extension component:
-
-1. Add the component to `superset-frontend/packages/superset-core/src/ui/components/`
-2. Export it from `superset-frontend/packages/superset-core/src/ui/components/index.ts`
-3. Create a Storybook story with an `Interactive` export:
-
-```tsx
-export default {
-  title: 'Extension Components/MyComponent',
-  component: MyComponent,
-  parameters: {
-    docs: {
-      description: {
-        component: 'Description of the component...',
-      },
-    },
-  },
-};
-
-export const InteractiveMyComponent = (args) => <MyComponent {...args} />;
-
-InteractiveMyComponent.args = {
-  variant: 'primary',
-  disabled: false,
-};
-
-InteractiveMyComponent.argTypes = {
-  variant: {
-    control: { type: 'select' },
-    options: ['primary', 'secondary'],
-  },
-  disabled: {
-    control: { type: 'boolean' },
-  },
-};
-```
-
-4. Run `yarn start` in `docs/` - the page generates automatically!

+# Editor Contributions
+
+Extensions can replace Superset's default text editors with custom implementations. This allows you to provide enhanced editing experiences using alternative editor frameworks like Monaco, CodeMirror, or custom solutions.
+
+## Overview
+
+Superset uses text editors in various places throughout the application:
+
+| Language | Locations |
+|----------|-----------|
+| `sql` | SQL Lab, Metric/Filter Popovers |
+| `json` | Dashboard Properties, Annotation Modal, Theme Modal |
+| `css` | Dashboard Properties, CSS Template Modal |
+| `markdown` | Dashboard Markdown component |
+| `yaml` | Template Params Editor |
+
+By registering an editor provider for a language, your extension replaces the default Ace editor in **all** locations that use that language.
+
+## Manifest Configuration
+
+Declare editor contributions in your `extension.json` manifest:
+
+```json
+{
+  "name": "monaco-editor",
+  "version": "1.0.0",
+  "frontend": {
+    "contributions": {
+      "editors": [
+        {
+          "id": "monaco-editor.sql",
+          "name": "Monaco SQL Editor",
+          "languages": ["sql"],
+          "description": "Monaco-based SQL editor with IntelliSense"
+        }
+      ]
+    }
+  }
+}
+```
+
+## Implementing an Editor
+
+Your editor component must implement the `EditorProps` interface and expose an `EditorHandle` via `forwardRef`. For the complete interface definitions, see `@apache-superset/core/api/editors.ts`.
+
+### Key EditorProps
+
+```typescript
+interface EditorProps {
+  /** Controlled value */
+  value: string;
+  /** Content change handler */
+  onChange: (value: string) => void;
+  /** Language mode for syntax highlighting */
+  language: EditorLanguage;
+  /** Keyboard shortcuts to register */
+  hotkeys?: EditorHotkey[];
+  /** Callback when editor is ready with imperative handle */
+  onReady?: (handle: EditorHandle) => void;
+  /** Host-specific context (e.g., database info from SQL Lab) */
+  metadata?: Record<string, unknown>;
+  // ... additional props for styling, annotations, etc.
+}
+```
+
+### Key EditorHandle Methods
+
+```typescript
+interface EditorHandle {
+  /** Focus the editor */
+  focus(): void;
+  /** Get the current editor content */
+  getValue(): string;
+  /** Get the current cursor position */
+  getCursorPosition(): Position;
+  /** Move the cursor to a specific position */
+  moveCursorToPosition(position: Position): void;
+  /** Set the selection range */
+  setSelection(selection: Range): void;
+  /** Scroll to a specific line */
+  scrollToLine(line: number): void;
+  // ... additional methods for text manipulation, annotations, etc.
+}
+```
+
+## Example Implementation
+
+Here's an example of a Monaco-based SQL editor implementing the key interfaces shown above:
+
+### MonacoSQLEditor.tsx
+

+      return () => editor.dispose();
+    }, []);
+
+    return <div ref={containerRef} style={{ height: '100%', width: '100%' }} />;
+  },
+);
+
+export default MonacoSQLEditor;
+```
+
+### activate.ts
+
+```typescript
+import { editors } from '@apache-superset/core';
+import MonacoSQLEditor from './MonacoSQLEditor';
+
+export function activate(context) {
+  // Register the Monaco editor for SQL
+  const disposable = editors.registerEditorProvider(
+    {
+      id: 'monaco-sql-editor.sql',
+      name: 'Monaco SQL Editor',
+      languages: ['sql'],
+    },
+    MonacoSQLEditor,
+  );
+
+  context.subscriptions.push(disposable);
+}
+```
+
+## Handling Hotkeys
+
+Superset passes keyboard shortcuts via the `hotkeys` prop. Each hotkey includes an `exec` function that receives the `EditorHandle`:
+
+```typescript
+interface EditorHotkey {
+  name: string;
+  key: string;  // e.g., "Ctrl-Enter", "Alt-Shift-F"
+  description?: string;
+  exec: (handle: EditorHandle) => void;
+}
+```
+
+Your editor must register these hotkeys with your editor framework and call `exec(handle)` when triggered.
+
+## Keywords
+
+Superset passes static autocomplete suggestions via the `keywords` prop. These include table names, column names, and SQL functions based on the current database context:
+
+```typescript
+interface EditorKeyword {
+  name: string;
+  value?: string;  // Text to insert (defaults to name)
+  meta?: string;   // Category like "table", "column", "function"
+  score?: number;  // Sorting priority
+}
+```
+
+Your editor should convert these to your framework's completion format and register them for autocomplete.
+
+## Completion Providers
+
+For dynamic autocomplete (e.g., fetching suggestions as the user types), implement and register a `CompletionProvider` via the `EditorHandle`:
+
+```typescript
+const provider: CompletionProvider = {
+  id: 'my-sql-completions',
+  triggerCharacters: ['.', ' '],
+  provideCompletions: async (content, position, context) => {
+    // Use context.metadata for database info
+    // Return array of CompletionItem
+    return [
+      { label: 'SELECT', insertText: 'SELECT', kind: 'keyword' },
+      // ...
+    ];
+  },
+};
+
+// Register during editor initialization
+const disposable = handle.registerCompletionProvider(provider);
+```

-# Extension Sandboxing
-
-Superset provides a tiered sandbox architecture for running extensions with varying levels of trust and isolation. This system balances security with functionality, allowing extensions to be safely executed based on their trust level and requirements.
-
-## Overview
-
-The sandbox system supports three tiers of trust:
-
-| Tier | Trust Level | Isolation | Use Case |
-|------|-------------|-----------|----------|
-| **Tier 1** | `core` | None (main context) | Official/signed extensions |
-| **Tier 2** | `iframe` | Browser sandbox | Community UI extensions |
-| **Tier 3** | `wasm` | WASM sandbox | Logic-only extensions |
-
-## Trust Levels
-
-### Tier 1: Core (Trusted)
-
-Core extensions run in the main JavaScript context with full access to Superset APIs, DOM, and browser capabilities. This is the same behavior as legacy extensions.
-
-**Requirements:**
-- Must be in the trusted extensions list, OR
-- `allowUnsignedCore` configuration must be enabled
-
-**Use cases:**
-- Official Apache Superset extensions
-- Enterprise-verified plugins
-- Extensions from trusted sources
-
-```json
-{
-  "id": "official-extension",
-  "sandbox": {
-    "trustLevel": "core",
-    "requiresSignature": true
-  }
-}
-```
-
-### Tier 2: Iframe (Semi-Trusted)
-
-Iframe-sandboxed extensions run in isolated browser sandboxes with controlled API access via postMessage. This provides strong browser-enforced isolation while still allowing full UI rendering.
-
-**Security features:**
-- Browser-enforced same-origin isolation
-- Content Security Policy (CSP) restrictions
-- Permission-based API access
-- No access to parent window's cookies, localStorage, or DOM
-
-**Use cases:**
-- Community-contributed extensions
-- Third-party plugins
-- Extensions that render custom UI
-
-```json
-{
-  "id": "community-extension",
-  "sandbox": {
-    "trustLevel": "iframe",
-    "permissions": ["sqllab:read", "notification:show"],
-    "csp": {
-      "connectSrc": ["https://api.example.com"]
-    }
-  }
-}
-```
-
-### Tier 3: WASM (Untrusted)
-
-WASM-sandboxed extensions run in a QuickJS WebAssembly sandbox with no DOM access. Only explicitly injected APIs are available. This provides the highest level of isolation.
-
-**Security features:**
-- Complete isolation from browser APIs
-- Memory limits to prevent DoS
-- Execution time limits
-- No network or DOM access
-
-**Use cases:**
-- Custom data transformations
-- Calculated fields and formatters
-- Data validation rules
-- Custom aggregation functions
-
-```json
-{
-  "id": "formatter-extension",
-  "sandbox": {
-    "trustLevel": "wasm",
-    "resourceLimits": {
-      "maxMemory": 10485760,
-      "maxExecutionTime": 5000
-    }
-  }
-}
-```
-
-## Permissions
-
-Sandboxed extensions (Tier 2 and 3) must declare the permissions they need. Permissions follow a least-privilege model.
-
-### Available Permissions
-
-| Permission | Description |
-|------------|-------------|
-| `api:read` | Read-only access to Superset APIs |
-| `api:write` | Write access to Superset APIs |
-| `sqllab:read` | Read SQL Lab state (queries, results) |
-| `sqllab:execute` | Execute SQL queries |
-| `dashboard:read` | Read dashboard data |
-| `dashboard:write` | Modify dashboards |
-| `chart:read` | Read chart data |
-| `chart:write` | Modify charts |
-| `user:read` | Read current user info |
-| `notification:show` | Show notifications to user |
-| `modal:open` | Open modal dialogs |
-| `navigation:redirect` | Navigate to other pages |
-| `clipboard:write` | Write to clipboard |
-| `download:file` | Trigger file downloads |
-
-### Example Permission Declaration
-
-```json
-{
-  "sandbox": {
-    "trustLevel": "iframe",
-    "permissions": [
-      "sqllab:read",
-      "notification:show",
-      "download:file"
-    ]
-  }
-}
-```
-
-## Sandboxed Extension API
-
-Extensions running in iframe sandboxes have access to a controlled API through the `window.superset` object.
-
-### SQL Lab API
-
-```typescript
-// Get the current SQL Lab tab (requires sqllab:read)
-const tab = await window.superset.sqlLab.getCurrentTab();
-
-// Get query results (requires sqllab:read)
-const results = await window.superset.sqlLab.getQueryResults(queryId);
-```
-
-### Dashboard API
-
-```typescript
-// Get dashboard context (requires dashboard:read)
-const context = await window.superset.dashboard.getContext();
-
-// Get dashboard filters (requires dashboard:read)
-const filters = await window.superset.dashboard.getFilters();
-```
-
-### Chart API
-
-```typescript
-// Get chart data (requires chart:read)
-const chartData = await window.superset.chart.getData(chartId);
-```
-
-### User API
-
-```typescript
-// Get current user (requires user:read)
-const user = await window.superset.user.getCurrentUser();
-```
-
-### UI API
-
-```typescript
-// Show notification (requires notification:show)
-window.superset.ui.showNotification('Success!', 'success');
-
-// Open modal (requires modal:open)
-const result = await window.superset.ui.openModal({
-  title: 'Confirm',
-  content: 'Are you sure?',
-  type: 'confirm'
-});
-
-// Navigate (requires navigation:redirect)
-window.superset.ui.navigateTo('/dashboard/1');
-```
-
-### Utility API
-
-```typescript
-// Copy to clipboard (requires clipboard:write)
-await window.superset.utils.copyToClipboard('text');
-
-// Download file (requires download:file)
-window.superset.utils.downloadFile(blob, 'filename.csv');
-
-// Get CSRF token (no permission required)
-const token = await window.superset.utils.getCSRFToken();
-```
-
-### Event Subscriptions
-
-```typescript
-// Subscribe to events
-const unsubscribe = window.superset.on('dashboard:filterChange', (filters) => {
-  console.log('Filters changed:', filters);
-});
-
-// Later, unsubscribe
-unsubscribe();
-```
-
-## Content Security Policy
-
-Iframe-sandboxed extensions can customize their Content Security Policy through the `csp` configuration:
-
-```json
-{
-  "sandbox": {
-    "trustLevel": "iframe",
-    "csp": {
-      "defaultSrc": ["'none'"],
-      "scriptSrc": ["'unsafe-inline'"],
-      "styleSrc": ["'unsafe-inline'"],
-      "imgSrc": ["data:", "blob:", "https://cdn.example.com"],
-      "connectSrc": ["https://api.example.com"],
-      "fontSrc": ["data:"]
-    }
-  }
-}
-```
-
-### Default CSP
-
-By default, iframe sandboxes use a restrictive CSP:
-
-```
-default-src 'none';
-script-src 'unsafe-inline';
-style-src 'unsafe-inline';
-img-src data: blob:;
-font-src data:;
-connect-src 'none';
-frame-src 'none';
-```
-
-## WASM Resource Limits
-
-WASM-sandboxed extensions can configure resource limits:
-
-```json
-{
-  "sandbox": {
-    "trustLevel": "wasm",
-    "resourceLimits": {
-      "maxMemory": 10485760,      // 10MB max memory
-      "maxExecutionTime": 5000,   // 5 second timeout
-      "maxStackSize": 1000        // Max call stack depth
-    }
-  }
-}
-```
-
-### Defaults
-
-- **maxMemory**: 10MB
-- **maxExecutionTime**: 5000ms (5 seconds)
-- **maxStackSize**: 1000 calls
-
-## Migration Guide
-
-### Migrating from Legacy Extensions
-
-Existing extensions that don't specify a `sandbox` configuration will continue to run as `core` extensions for backward compatibility. To migrate to a sandboxed model:
-
-1. **Assess your extension's requirements**:
-   - Does it need to render UI? Use `iframe`
-   - Is it logic-only (formatters, validators)? Use `wasm`
-   - Does it need full access? Keep as `core` (requires trust)
-
-2. **Add sandbox configuration to extension.json**:
-
-```json
-{
-  "sandbox": {
-    "trustLevel": "iframe",
-    "permissions": ["sqllab:read"]
-  }
-}
-```
-
-3. **Update your code to use the sandboxed API**:
-
-Before (core extension):
-```typescript
-import { sqlLab } from '@apache-superset/core';
-const tab = sqlLab.getCurrentTab();
-```
-
-After (sandboxed extension):
-```typescript
-const tab = await window.superset.sqlLab.getCurrentTab();
-```
-
-4. **Test thoroughly** to ensure all functionality works within the sandbox
-
-## Security Comparison
-
-| Aspect | Core | Iframe | WASM |
-|--------|------|--------|------|
-| DOM Access | Full | Own iframe only | None |
-| Network | Full | Restricted (CSP) | None |
-| Cookies | Full | None | None |
-| localStorage | Full | None | None |
-| Superset APIs | Full | Controlled bridge | Injected only |
-| Performance | Native | Near-native | ~40% slower |
-| React rendering | Full | Own instance | Via descriptors |
-
-## Administrator Configuration
-
-Administrators can configure trust settings for their Superset deployment:
-
-```python
-# In superset_config.py
-EXTENSIONS_TRUST_CONFIG = {
-    # Extensions allowed to run as 'core'
-    "trusted_extensions": [
-        "official-extension-1",
-        "enterprise-plugin",
-    ],
-
-    # Allow unsigned extensions to run as core (not recommended for production)
-    "allow_unsigned_core": False,
-
-    # Default trust level for extensions without sandbox config
-    "default_trust_level": "iframe",
-}
-```
-
-## Best Practices
-
-1. **Request minimal permissions** - Only request the permissions your extension actually needs
-
-2. **Prefer iframe over core** - Unless your extension requires deep integration, use iframe sandboxing
-
-3. **Use WASM for pure logic** - If your extension doesn't need UI, WASM provides the best isolation
-
-4. **Handle permission denials gracefully** - Your extension should degrade gracefully if a permission is not granted
-
-5. **Don't store sensitive data** - Sandboxed extensions should not store sensitive user data
-
-6. **Test in sandboxed mode** - Always test your extension in its intended sandbox environment
-
-## Troubleshooting
-
-### Permission Denied Errors
-
-If you see "Permission denied" errors, verify that:
-1. The permission is declared in your extension.json
-2. The permission was granted by the administrator
-3. You're calling the correct API method for that permission
-
-### Timeout Errors (WASM)
-
-If your WASM extension times out:
-1. Optimize your code for faster execution
-2. Request a higher `maxExecutionTime` limit
-3. Break large operations into smaller chunks
-
-### CSP Violations (Iframe)
-
-If resources fail to load due to CSP:
-1. Add the required domains to your CSP configuration
-2. Ensure you're using HTTPS for external resources
-3. Avoid inline scripts and styles where possible
-
-### Core Trust Denied
-
-If your extension is downgraded from `core` to another trust level:
-1. Check if the extension ID is in the administrator's `trusted_extensions` list
-2. If signature verification is required, ensure the extension is signed
-3. Verify the signing key is in the administrator's `trusted_signers`
-
-See [Extension Signing](./signing) for how to sign your extension.

 By default, extensions are disabled and must be explicitly enabled by setting the `ENABLE_EXTENSIONS` feature flag. Built-in extensions are included as part of the Superset codebase and are held to the same security standards and review processes as the rest of the application.
 
-## Extension Sandboxing
+For external extensions, administrators are responsible for evaluating and verifying the security of any extensions they choose to install, just as they would when installing third-party NPM or PyPI packages. At this stage, all extensions run in the same context as the host application, without additional sandboxing. This means that external extensions can impact the security and performance of a Superset environment in the same way as any other installed dependency.
 
-Superset provides a tiered sandbox architecture for running extensions with varying levels of trust and isolation. Extensions can declare their trust level and permissions in their manifest, and Superset will load them in the appropriate sandbox:
-
-- **Core (Tier 1)**: Trusted extensions run in the main context with full access
-- **Iframe (Tier 2)**: Semi-trusted extensions run in browser-sandboxed iframes
-- **WASM (Tier 3)**: Untrusted logic runs in WebAssembly sandboxes
-
-For detailed information about the sandbox system, see [Extension Sandboxing](./sandbox).
-
-## Trust Model
-
-Administrators are responsible for evaluating and verifying the security of any extensions they choose to install. Superset's sandbox system provides defense-in-depth:
-
-1. **Core extensions** require explicit trust configuration and optionally signature verification
-2. **Iframe-sandboxed extensions** are isolated by the browser's same-origin policy
-3. **WASM-sandboxed extensions** have no access to browser APIs
-
-A directory of community extensions is available in the [Community Extensions](./registry) page. Note that these extensions are not vetted by the Apache Superset project—administrators must evaluate each extension before installation.
-
-## Extension Signing
-
-Extensions can be cryptographically signed to verify their authenticity and integrity. This is required for extensions that need `core` trust level in production environments with signature verification enabled.
-
-- **Developers**: See [Extension Signing](./signing) to learn how to sign your extensions
-- **Administrators**: See [Administrator Configuration](./admin-configuration) to configure trusted signers
-
-## Administrator Configuration
-
-Superset provides extensive configuration options for controlling extension trust levels, signature verification, and security policies. Key settings include:
-
-- **Trusted extensions list**: Extensions allowed to run as `core`
-- **Signature verification**: Require valid signatures for core trust
-- **Default trust level**: Sandbox level for unlisted extensions
-
-For complete configuration details, see [Administrator Configuration](./admin-configuration).
-
-## Security Reporting
+We plan to introduce an optional sandboxed execution model for extensions in the future (as part of an additional SIP). Until then, administrators should exercise caution and follow best practices when selecting and deploying third-party extensions. A directory of community extensions is available in the [Community Extensions](./registry) page. Note that these extensions are not vetted by the Apache Superset project—administrators must evaluate each extension before installation.
 
 **Any performance or security vulnerabilities introduced by external extensions should be reported directly to the extension author, not as Superset vulnerabilities.**

-# Extension Signing
-
-Signing your extension allows administrators to verify its authenticity and integrity. Signed extensions can run as `core` trust level in production environments where signature verification is required.
-
-## Why Sign Extensions?
-
-- **Trust**: Administrators can verify your extension comes from a known source
-- **Integrity**: Ensures the extension hasn't been modified since you signed it
-- **Core Access**: Required for extensions needing `core` trust level in secured deployments
-- **Distribution**: Makes your extension suitable for enterprise environments
-
-## Generating Signing Keys
-
-Generate a new Ed25519 keypair for signing your extensions:
-
-```bash
-superset-extensions generate-keys --output my-signing-key.pem
-```
-
-This creates two files:
-
-| File | Purpose | Share? |
-|------|---------|--------|
-| `my-signing-key.pem` | Private key for signing | **Never share!** |
-| `my-signing-key.pub` | Public key for verification | Share with administrators |
-
-**Output example:**
-
-```
-✅ Private key: my-signing-key.pem
-✅ Public key:  my-signing-key.pub
-   Fingerprint: MCowBQYDK2Vw...
-
-⚠️  Keep the private key secure! Only share the public key with administrators.
-
-Usage:
-  Sign an extension:  superset-extensions bundle --sign my-signing-key.pem
-  Share with admins:  my-signing-key.pub
-```
-
-## Signing an Extension
-
-### During Bundle
-
-The easiest way to sign is during the bundle step:
-
-```bash
-superset-extensions bundle --sign my-signing-key.pem
-```
-
-This builds, signs the manifest, and creates the `.supx` bundle in one command.
-
-**Output:**
-
-```
-✅ Full build completed in dist/
-✅ Manifest signed
-✅ Bundle created (signed): my-extension-1.0.0.supx
-```
-
-### Signing Existing Manifest
-
-To sign an already-built manifest:
-
-```bash
-superset-extensions sign --key my-signing-key.pem --manifest dist/manifest.json
-```
-
-This creates `dist/manifest.sig` containing the signature.
-
-## Bundle Structure
-
-A signed extension bundle contains:
-
-```
-my-extension-1.0.0.supx
-├── manifest.json       # Extension manifest
-├── manifest.sig        # Ed25519 signature (base64-encoded)
-├── frontend/dist/      # Frontend assets
-└── backend/src/        # Backend code (if applicable)
-```
-
-The signature file (`manifest.sig`) contains a base64-encoded Ed25519 signature of the manifest content.
-
-## Distributing Your Public Key
-
-Share your public key (`.pub` file) with administrators who want to trust your extensions:
-
-1. **Direct sharing**: Send the `.pub` file via secure channels
-2. **Documentation**: Include in your extension's README
-3. **Website**: Host on your organization's website with HTTPS
-
-Administrators will add your public key to their `EXTENSIONS_TRUST_CONFIG.trusted_signers` configuration.
-
-### Key Fingerprint
-
-The fingerprint helps administrators verify they have the correct key. Include it in your documentation:
-
-```
-Public Key Fingerprint: MCowBQYDK2Vw...
-```
-
-Administrators should verify this fingerprint matches when adding your key.
-
-## Security Best Practices
-
-### Protect Your Private Key
-
-- **Never commit** private keys to version control
-- **Use secure storage** like hardware security modules (HSM) for production keys
-- **Limit access** to the private key to authorized personnel only
-- **Back up securely** in case of key loss
-
-### Key Rotation
-
-Consider rotating keys periodically:
-
-1. Generate a new keypair
-2. Notify administrators of the new public key
-3. Sign new releases with the new key
-4. Keep the old key available for verifying existing releases
-
-### Multiple Keys
-
-For organizations, consider separate keys for:
-
-- Development/testing releases
-- Production releases
-- Different product teams
-
-## Requesting Core Trust
-
-If your extension needs `core` trust level:
-
-1. **Sign your extension** using the process above
-2. **Document your public key** with fingerprint
-3. **Explain why core is needed** in your extension documentation
-4. **Provide your public key** to administrators
-
-Administrators will then:
-1. Add your public key to `trusted_signers`
-2. Enable `require_core_signatures: True`
-3. Your signed extension can now run as `core`
-
-## Verification Process
-
-When Superset loads your extension:
-
-1. Reads `manifest.json` and `manifest.sig` from the bundle
-2. Checks if the extension requests `core` trust level
-3. If `require_core_signatures` is enabled, verifies the signature
-4. Checks the signature against all keys in `trusted_signers`
-5. If verification passes, grants the requested trust level
-6. If verification fails, downgrades to `default_trust_level`
-
-## Troubleshooting
-
-### "Signature verification failed"
-
-- Ensure you're using the matching private key for the public key given to admins
-- Verify the manifest wasn't modified after signing
-- Check that the `.sig` file was included in the bundle
-
-### "Private key must be Ed25519"
-
-- The signing system only supports Ed25519 keys
-- Generate a new key using `superset-extensions generate-keys`
-
-### Administrator Reports Invalid Signature
-
-- Verify the public key file wasn't corrupted during transfer
-- Confirm the fingerprint matches between your key and theirs
-- Re-sign the extension and redistribute
-
-## Technical Details
-
-### Signature Algorithm
-
-Extensions use **Ed25519** signatures:
-
-- Fast signature generation and verification
-- Small signature size (64 bytes)
-- Strong security guarantees
-- Deterministic signatures (same input always produces same output)
-
-### Signature Format
-
-The `manifest.sig` file contains:
-
-```
-<base64-encoded Ed25519 signature>
-```
-
-The signature is computed over the raw bytes of `manifest.json`.
-
-### Key Format
-
-Keys are stored in PEM format:
-
-**Private key:**
-```
------BEGIN PRIVATE KEY-----
-MC4CAQAwBQYDK2VwBCIEI...
------END PRIVATE KEY-----
-```
-
-**Public key:**
-```
------BEGIN PUBLIC KEY-----
-MCowBQYDK2VwAyEA...
------END PUBLIC KEY-----
-```

+# Storybook
+
+Superset uses [Storybook](https://storybook.js.org/) for developing and testing UI components in isolation. Storybook provides a sandbox to build components independently, outside of the main application.
+
+## Public Storybook
+
+A public Storybook with components from the `master` branch is available at:
+
+**[apache-superset.github.io/superset-ui](https://apache-superset.github.io/superset-ui/?path=/story/*)**
+
+## Running Locally
+
+### Main Superset Storybook
+
+To run the main Superset Storybook locally:
+
+```bash
+cd superset-frontend
+
+# Start Storybook (opens at http://localhost:6006)
+npm run storybook
+
+# Build static Storybook
+npm run build-storybook
+```
+
+### @superset-ui Package Storybook
+
+The `@superset-ui` packages have a separate Storybook for component library development:
+
+```bash
+cd superset-frontend
+
+# Install dependencies and bootstrap packages
+npm ci && npm run bootstrap
+
+# Start the @superset-ui Storybook (opens at http://localhost:9001)
+cd packages/superset-ui-demo
+npm run storybook
+```
+
+## Adding Stories
+
+### To an Existing Package
+
+If stories already exist for the package, extend the `examples` array in the package's story file:
+
+```
+storybook/stories/<package>/index.js
+```
+
+### To a New Package
+
+1. Add package dependencies:
+
+   ```bash
+   npm install <package>
+   ```
+
+2. Create a story folder matching the package name:
+
+   ```bash
+   mkdir storybook/stories/superset-ui-<package>/
+   ```
+
+3. Create an `index.js` file with the story configuration:
+
+   ```javascript
+   export default {
+     examples: [
+       {
+         storyPath: '@superset-ui/package',
+         storyName: 'My Story',
+         renderStory: () => <MyComponent />,
+       },
+     ],
+   };
+   ```
+
+   Use the `|` separator for nested stories:
+   ```javascript
+   storyPath: '@superset-ui/package|Category|Subcategory'
+   ```
+
+## Best Practices
+
+- **Isolate components**: Stories should render components in isolation, without application context
+- **Show variations**: Create stories for different states, sizes, and configurations
+- **Document props**: Use Storybook's controls to expose configurable props
+- **Test edge cases**: Include stories for loading states, error states, and empty states

+<FAQSchema faqs={[
+  {
+    question: "How big of a dataset can Superset handle?",
+    answer: "Superset can work with even gigantic databases. Superset acts as a thin layer above your underlying databases or data engines, which do all the processing. Superset simply visualizes the results of the query. The key to achieving acceptable performance is whether your database can execute queries and return results at acceptable speed."
+  },
+  {
+    question: "What are the computing specifications required to run Superset?",
+    answer: "The specs depend on how many users you have and their activity, not on the size of your data. Community members have reported 8GB RAM, 2vCPUs as adequate for a moderately-sized instance. Monitor your resource usage and adjust as needed."
+  },
+  {
+    question: "Can I join or query multiple tables at one time?",
+    answer: "Not in the Explore or Visualization UI directly. A Superset SQLAlchemy datasource can only be a single table or a view. You can create a view that joins tables, or use SQL Lab where you can write SQL queries to join multiple tables."
+  },
+  {
+    question: "How do I create my own visualization?",
+    answer: "Read the instructions in the Creating Visualization Plugins documentation to learn how to build custom visualizations for Superset."
+  },
+  {
+    question: "Can I upload and visualize CSV data?",
+    answer: "Yes! Superset supports CSV upload functionality. Read the Exploring Data documentation to learn how to enable and use CSV upload."
+  },
+  {
+    question: "Why are my queries timing out?",
+    answer: "There are many possible causes. For SQL Lab, Superset allows queries to run up to 6 hours by default (configurable via SQLLAB_ASYNC_TIME_LIMIT_SEC). For dashboard timeouts, check your gateway/proxy timeout settings and adjust SUPERSET_WEBSERVER_TIMEOUT in superset_config.py."
+  },
+  {
+    question: "Why is the map not visible in the geospatial visualization?",
+    answer: "You need to register a free account at Mapbox.com, obtain an API key, and add it to your .env file at the key MAPBOX_API_KEY."
+  },
+  {
+    question: "What database engine can I use as a backend for Superset?",
+    answer: "Superset is tested using MySQL, PostgreSQL, and SQLite backends for storing its internal metadata. While Superset supports many databases as data sources, only these are recommended for the metadata store in production."
+  },
+  {
+    question: "Does Superset work with my database?",
+    answer: "Superset supports any database with a Python SQLAlchemy dialect and DBAPI driver. Check the Connecting to Databases documentation for the full list of supported databases."
+  },
+  {
+    question: "Does Superset offer a public API?",
+    answer: "Yes, Superset has a public REST API documented using Swagger. Enable FAB_API_SWAGGER_UI in superset_config.py to access interactive API documentation at /swagger/v1."
+  },
+  {
+    question: "Does Superset collect any telemetry data?",
+    answer: "Superset uses Scarf by default to collect basic telemetry data to help maintainers understand version usage. Users can opt out by setting the SCARF_ANALYTICS environment variable to false."
+  },
+  {
+    question: "Does Superset have a trash bin to recover deleted assets?",
+    answer: "No, there is no built-in way to recover deleted dashboards, charts, or datasets. It is recommended to take periodic backups of the metadata database and use export functionality for recovery."
