+# JavaScript to TypeScript Migration Agent Guide
+
+**Complete technical reference for converting JavaScript/JSX files to TypeScript/TSX in Apache Superset frontend.**
+
+**Agent Role:** Atomic migration unit - migrate the core file + ALL related tests/mocks as one cohesive unit. Use `git mv` to preserve history, NO `git commit`. NO global import changes. Report results upon completion.
+
+---
+
+## 🎯 Migration Principles
+
+1. **Atomic migration units** - Core file + all related tests/mocks migrate together
+2. **Zero `any` types** - Use proper TypeScript throughout
+3. **Leverage existing types** - Reuse established definitions
+4. **Type inheritance** - Derivatives extend base component types
+5. **Strategic placement** - File types for maximum discoverability
+6. **Surgical improvements** - Enhance existing types during migration
+
+---
+
+## Step 0: Dependency Check (MANDATORY)
+
+**Command:**
+```bash
+grep -E "from '\.\./.*\.jsx?'|from '\./.*\.jsx?'|from 'src/.*\.jsx?'" superset-frontend/{filename}
+```
+
+**Decision:**
+- ✅ No matches → Proceed with atomic migration (core + tests + mocks)
+- ❌ Matches found → EXIT with dependency report (see format below)
+
+---
+
+## Step 1: Identify Related Files (REQUIRED)
+
+**Atomic Migration Scope:**
+For core file `src/utils/example.js`, also migrate:
+- `src/utils/example.test.js` / `src/utils/example.test.jsx`
+- `src/utils/example.spec.js` / `src/utils/example.spec.jsx`
+- `src/utils/__mocks__/example.js`
+- Any other related test/mock files found by pattern matching
+
+**Find all related test and mock files:**
+```bash
+# Pattern-based search for related files
+basename=$(basename {filename} .js)
+dirname=$(dirname superset-frontend/{filename})
+
+# Find test files
+find "$dirname" -name "${basename}.test.js" -o -name "${basename}.test.jsx"
+find "$dirname" -name "${basename}.spec.js" -o -name "${basename}.spec.jsx"
+
+# Find mock files  
+find "$dirname" -name "__mocks__/${basename}.js"
+find "$dirname" -name "${basename}.mock.js"
+```
+
+**Migration Requirement:** All discovered related files MUST be migrated together as one atomic unit.
+
+**Test File Creation:** If NO test files exist for the core file, CREATE a minimal test file using the following pattern:
+- Location: Same directory as core file
+- Name: `{basename}.test.ts` (e.g., `DebouncedMessageQueue.test.ts`)
+- Content: Basic test structure importing and testing the main functionality
+- Use proper TypeScript types in test file

+
+### From `@superset-ui/core`

+```
+
+### From `@superset-ui/chart-controls`
+```typescript
+Dataset, ColumnMeta, ControlStateMapping
+```
+
+### From Local Types (`src/types/`)
+```typescript
+// Authentication
+User, UserWithPermissionsAndRoles, BootstrapUser, PermissionsAndRoles
+
+// Dashboard
+Dashboard, DashboardState, DashboardInfo, DashboardLayout, LayoutItem
+ComponentType, ChartConfiguration, ActiveFilters
+

+ChartCrossFiltersConfig, ActiveTabs, MenuKeys
+
+// src/explore/types.ts  
+ExplorePageInitialData, ExplorePageState, ExploreResponsePayload, OptionSortType
+
+// src/SqlLab/types.ts
+[SQL Lab specific types]
+```
+
+---
+
+## 🏗️ Type Organization Strategy
+
+### Type Placement Hierarchy
+
+1. **Component-Colocated** (90% of cases)
+   ```typescript
+   // Same file as component
+   interface MyComponentProps {
+     title: string;
+     onClick: () => void;
+   }
+   ```
+
+2. **Feature-Shared**
+   ```typescript
+   // src/[domain]/components/[Feature]/types.ts
+   export interface FilterConfiguration {
+     filterId: string;
+     targets: NativeFilterTarget[];
+   }
+   ```
+
+3. **Domain-Wide**
+   ```typescript
+   // src/[domain]/types.ts
+   export interface ExploreFormData extends QueryFormData {
+     viz_type: string;
+   }
+   ```
+
+4. **Global**
+   ```typescript
+   // src/types/[TypeName].ts
+   export interface ApiResponse<T> {
+     result: T;
+     count?: number;
+   }
+   ```
+
+### Type Discovery Commands
+```bash
+# Search existing types before creating
+find superset-frontend/src -name "types.ts" -exec grep -l "[TypeConcept]" {} \;
+grep -r "interface.*Props\|type.*Props" superset-frontend/src/
+```
+
+### Derivative Component Patterns
+
+**Rule:** Components that extend others should extend their type interfaces.
+
+```typescript
+// ✅ Base component type
+interface SelectProps {
+  value: string | number;
+  options: SelectOption[];
+  onChange: (value: string | number) => void;
+  disabled?: boolean;
+}
+
+// ✅ Derivative extends base
+interface ChartSelectProps extends SelectProps {
+  charts: Chart[];
+  onChartSelect: (chart: Chart) => void;
+}
+
+// ✅ Derivative with modified props  
+interface DatabaseSelectProps extends Omit<SelectProps, 'value' | 'onChange'> {
+  value: number;  // Narrowed type
+  onChange: (databaseId: number) => void;  // Specific signature
+}
+```
+
+**Common Patterns:**
+- **Extension:** `extends BaseProps` - adds new props
+- **Omission:** `Omit<BaseProps, 'prop'>` - removes props
+- **Modification:** `Omit<BaseProps, 'prop'> & { prop: NewType }` - changes prop type
+- **Restriction:** Override with narrower types (union → specific)
+

+
+## 📋 Migration Recipe
+
+### Step 2: File Conversion
+```bash
+# Use git mv to preserve history
+git mv component.js component.ts
+git mv Component.jsx Component.tsx
+```
+
+### Step 3: Import & Type Setup
+```typescript
+// Import order (enforced by linting)
+import { FC, ReactNode } from 'react';
+import { JsonObject, QueryFormData } from '@superset-ui/core';
+import { Dataset } from '@superset-ui/chart-controls';
+import type { Dashboard } from 'src/types/Dashboard';
+```
+
+### Step 4: Function & Component Typing
+```typescript
+// Functions with proper parameter/return types
+export function processData(
+  data: Dataset[],
+  config: JsonObject
+): ProcessedData[] {
+  // implementation
+}
+
+// Component props with inheritance
+interface ComponentProps extends BaseProps {
+  data: Chart[];
+  onSelect: (id: number) => void;
+}
+
+const Component: FC<ComponentProps> = ({ data, onSelect }) => {
+  // implementation
+};
+```
+
+### Step 5: State & Redux Typing
+```typescript
+// Hooks with specific types
+const [data, setData] = useState<Chart[]>([]);
+const [selected, setSelected] = useState<number | null>(null);
+
+// Redux with existing RootState
+const mapStateToProps = (state: RootState) => ({
+  charts: state.charts,
+  user: state.user,
+});
+```
+

+
+## 🧠 Type Debugging Strategies (Real-World Learnings)
+
+### The Evolution of Type Approaches
+When you hit type errors, follow this debugging evolution:
+
+#### 1. ❌ Idealized Union Types (First Attempt)
+```typescript
+// Looks clean but doesn't match reality
+type DatasourceInput = Datasource | QueryEditor;
+```
+**Problem**: Real calling sites pass variations, not exact types.
+
+#### 2. ❌ Overly Precise Types (Second Attempt)
+```typescript
+// Tried to match exact calling signatures
+type DatasourceInput =
+  | IDatasource  // From DatasourcePanel
+  | (QueryEditor & { columns: ColumnMeta[] });  // From SaveQuery
+```
+**Problem**: Too rigid, doesn't handle legacy variations.
+
+#### 3. ✅ Flexible Interface (Final Solution)
+```typescript
+// Captures what the function actually needs
+interface DatasourceInput {
+  name?: string | null;  // Allow null for compatibility
+  datasource_name?: string | null;  // Legacy variations
+  columns?: any[];  // Multiple column types accepted
+  database?: { id?: number };
+  // ... other optional properties
+}
+```
+**Success**: Works with all calling sites, focuses on function needs.
+
+### Type Debugging Process
+1. **Start with compilation errors** - they show exact mismatches
+2. **Examine actual usage** - look at calling sites, not idealized types  
+3. **Build flexible interfaces** - capture what functions need, not rigid contracts
+4. **Iterate based on downstream validation** - let calling sites guide your types
+
+---
+
+## 🚨 Anti-Patterns to Avoid
+
+```typescript
+// ❌ Never use any
+const obj: any = {};
+
+// ✅ Use proper types
+const obj: Record<string, JsonObject> = {};
+
+// ❌ Don't recreate base component props
+interface ChartSelectProps {
+  value: string;     // Duplicated from SelectProps
+  onChange: () => void;  // Duplicated from SelectProps
+  charts: Chart[];   // New prop
+}
+
+// ✅ Inherit and extend
+interface ChartSelectProps extends SelectProps {
+  charts: Chart[];   // Only new props
+}
+
+// ❌ Don't create ad-hoc type variations
+interface UserInfo {
+  name: string;
+  email: string;
+}
+
+// ✅ Extend existing types (DRY principle)
+import { User } from 'src/types/bootstrapTypes';
+type UserDisplayInfo = Pick<User, 'firstName' | 'lastName' | 'email'>;
+
+// ❌ Don't create overly rigid unions
+type StrictInput = ExactTypeA | ExactTypeB;
+
+// ✅ Create flexible interfaces for function parameters
+interface FlexibleInput {
+  // Focus on what the function actually needs
+  commonProperty: string;
+  optionalVariations?: any;  // Allow for legacy variations
+}
+```
+
+## 📍 DRY Type Guidelines (WHERE TYPES BELONG)
+
+### Type Placement Rules
+**CRITICAL**: Type variations must live close to where they belong, not scattered across files.
+
+#### ✅ Proper Type Organization
+```typescript
+// ❌ Don't create one-off interfaces in utility files
+// src/utils/datasourceUtils.ts
+interface DatasourceInput { /* custom interface */ }  // Wrong!
+
+// ✅ Use existing types or extend them in their proper domain
+// src/utils/datasourceUtils.ts
+import { IDatasource } from 'src/explore/components/DatasourcePanel';
+import { QueryEditor } from 'src/SqlLab/types';
+
+// Create flexible interface that references existing types
+interface FlexibleDatasourceInput {
+  // Properties that actually exist across variations
+}
+```
+
+#### Type Location Hierarchy
+1. **Domain Types**: `src/{domain}/types.ts` (dashboard, explore, SqlLab)
+2. **Component Types**: Co-located with components  
+3. **Global Types**: `src/types/` directory
+4. **Utility Types**: Only when they truly don't belong elsewhere
+
+#### ✅ DRY Type Patterns
+```typescript
+// ✅ Extend existing domain types
+interface SaveQueryData extends Pick<QueryEditor, 'sql' | 'dbId' | 'catalog'> {
+  columns: ColumnMeta[];  // Add what's needed
+}
+
+// ✅ Create flexible interfaces for cross-domain utilities
+interface CrossDomainInput {
+  // Common properties that exist across different source types
+  name?: string | null;  // Accommodate legacy null values
+  // Only include properties the function actually uses
+}
+```
+
+---
+
+## 🎯 PropTypes Auto-Generation (Elegant Approach)
+
+**IMPORTANT**: Superset has `babel-plugin-typescript-to-proptypes` configured to automatically generate PropTypes from TypeScript interfaces. Use this instead of manual PropTypes duplication!
+
+### ❌ Manual PropTypes Duplication (Avoid This)
+```typescript
+export interface MyComponentProps {
+  title: string;
+  count?: number;
+}
+
+// 8+ lines of manual PropTypes duplication 😱
+const propTypes = PropTypes.shape({
+  title: PropTypes.string.isRequired,
+  count: PropTypes.number,
+});
+
+export default propTypes;
+```
+
+### ✅ Auto-Generated PropTypes (Use This)
+```typescript
+import { InferProps } from 'prop-types';
+
+export interface MyComponentProps {
+  title: string;
+  count?: number;
+}
+
+// Single validator function - babel plugin auto-generates PropTypes! ✨
+export default function MyComponentValidator(props: MyComponentProps) {
+  return null; // PropTypes auto-assigned by babel-plugin-typescript-to-proptypes
+}
+
+// Optional: For consumers needing PropTypes type inference
+export type MyComponentPropsInferred = InferProps<typeof MyComponentValidator>;
+```
+
+### Migration Pattern for Type-Only Files
+
+**When migrating type-only files with manual PropTypes:**
+
+1. **Keep the TypeScript interfaces** (single source of truth)
+2. **Replace manual PropTypes** with validator function
+3. **Remove PropTypes imports** and manual shape definitions
+4. **Add InferProps import** if type inference needed
+
+**Example Migration:**
+```typescript
+// Before: 25+ lines with manual PropTypes duplication
+export interface AdhocFilterType { /* ... */ }
+const adhocFilterTypePropTypes = PropTypes.oneOfType([...]);
+
+// After: 3 lines with auto-generation
+export interface AdhocFilterType { /* ... */ }
+export default function AdhocFilterValidator(props: { filter: AdhocFilterType }) {
+  return null; // Auto-generated PropTypes by babel plugin
+}
+```
+
+### Component PropTypes Pattern
+
+**For React components, the babel plugin works automatically:**
+
+```typescript
+interface ComponentProps {
+  title: string;
+  onClick: () => void;
+}
+
+const MyComponent: FC<ComponentProps> = ({ title, onClick }) => {
+  // Component implementation
+};
+
+// PropTypes automatically generated by babel plugin - no manual work needed!
+export default MyComponent;
+```
+
+### Auto-Generation Benefits
+
+- ✅ **Single source of truth**: TypeScript interfaces drive PropTypes
+- ✅ **No duplication**: Eliminate 15-20 lines of manual PropTypes code
+- ✅ **Automatic updates**: Changes to TypeScript automatically update PropTypes
+- ✅ **Type safety**: Compile-time checking ensures PropTypes match interfaces
+- ✅ **Backward compatibility**: Existing JavaScript components continue working
+
+### Babel Plugin Configuration
+
+The plugin is already configured in `babel.config.js`:
+```javascript
+['babel-plugin-typescript-to-proptypes', { loose: true }]
+```
+
+**No additional setup required** - just use TypeScript interfaces and the plugin handles the rest!
+
+---
+
+## 🧪 Test File Migration Patterns
+
+### Test File Priority
+- **Always migrate test files** alongside production files
+- **Test files are often leaf nodes** - good starting candidates
+- **Create tests if missing** - Leverage new TypeScript types for better test coverage
+
+### Test-Specific Type Patterns
+```typescript
+// Mock interfaces for testing
+interface MockStore {
+  getState: () => Partial<RootState>;  // Partial allows minimal mocking
+}
+
+// Type-safe mocking for complex objects
+const mockDashboardInfo: Partial<DashboardInfo> as DashboardInfo = {
+  id: 123,
+  json_metadata: '{}',
+};
+
+// Sinon stub typing
+let postStub: sinon.SinonStub;
+beforeEach(() => {
+  postStub = sinon.stub(SupersetClient, 'post');
+});
+
+// Use stub reference instead of original method
+expect(postStub.callCount).toBe(1);
+expect(postStub.getCall(0).args[0].endpoint).toMatch('/api/');
+```
+
+### Test Migration Recipe
+1. **Migrate production file first** (if both need migration)
+2. **Update test imports** to point to `.ts/.tsx` files
+3. **Add proper mock typing** using `Partial<T> as T` pattern
+4. **Fix stub typing** - Use stub references, not original methods
+5. **Verify all tests pass** with TypeScript compilation
+
+---
+
+## 🔧 Type Conflict Resolution
+
+### Multiple Type Definitions Issue
+**Problem**: Same type name defined in multiple files causes compilation errors.
+
+**Example**: `DashboardInfo` defined in both:
+- `src/dashboard/reducers/types.ts` (minimal)
+- `src/dashboard/components/Header/types.ts` (different shape)  
+- `src/dashboard/types.ts` (complete - used by RootState)
+
+### Resolution Strategy
+1. **Identify the authoritative type**:
+   ```bash
+   # Find which type is used by RootState/main interfaces
+   grep -r "DashboardInfo" src/dashboard/types.ts
+   ```
+
+2. **Use import from authoritative source**:
+   ```typescript
+   // ✅ Import from main domain types
+   import { RootState, DashboardInfo } from 'src/dashboard/types';
+
+   // ❌ Don't import from component-specific files
+   import { DashboardInfo } from 'src/dashboard/components/Header/types';
+   ```
+
+3. **Mock complex types in tests**:
+   ```typescript
+   // For testing - provide minimal required fields
+   const mockInfo: Partial<DashboardInfo> as DashboardInfo = {
+     id: 123,
+     json_metadata: '{}',
+     // Only provide fields actually used in test
+   };
+   ```
+
+### Type Hierarchy Discovery Commands
+```bash
+# Find all definitions of a type
+grep -r "interface.*TypeName\|type.*TypeName" src/
+
+# Find import usage patterns
+grep -r "import.*TypeName" src/
+
+# Check what RootState uses
+grep -A 10 -B 10 "TypeName" src/*/types.ts
+```
+
+---
+
+## Agent Constraints (CRITICAL)
+
+1. **Use git mv** - Run `git mv file.js file.ts` to preserve git history, but NO `git commit`
+2. **NO global import changes** - Don't update imports across codebase
+3. **Type files OK** - Can modify existing type files to improve/align types
+4. **Single-File TypeScript Validation** (CRITICAL) - tsc has known issues with multi-file compilation:
+   - **Core Issue**: TypeScript's `tsc` has documented problems validating multiple files simultaneously in complex projects
+   - **Solution**: ALWAYS validate files one at a time using individual `tsc` calls
+   - **Command Pattern**: `cd superset-frontend && npx tscw --noEmit --allowJs --composite false --project tsconfig.json {single-file-path}`
+   - **Why**: Multi-file validation can produce false positives, miss real errors, and conflict during parallel agent execution
+5. **Downstream Impact Validation** (CRITICAL) - Your migration affects calling sites:
+   - **Find downstream files**: `find superset-frontend/src -name "*.tsx" -o -name "*.ts" | xargs grep -l "your-core-filename" 2>/dev/null || echo "No files found"`
+   - **Validate each downstream file individually**: `cd superset-frontend && npx tscw --noEmit --allowJs --composite false --project tsconfig.json {each-downstream-file}`
+   - **Fix type mismatches** you introduced in calling sites
+   - **NEVER ignore downstream errors** - they indicate your types don't match reality
+6. **Avoid Project-Wide Validation During Migration**:
+   - **NEVER use `npm run type`** during parallel agent execution - produces unreliable results
+   - **Single-file validation is authoritative** - trust individual file checks over project-wide scans
+6. **ESLint validation** - Run `npm run eslint -- --fix {file}` for each migrated file to auto-fix formatting/linting issues
+6. Zero `any` types - use proper TypeScript types
+7. Search existing types before creating new ones
+8. Follow patterns from this guide
+

+# JS-to-TS Coordinator Workflow
+
+**Role:** Strategic migration coordination - select leaf-node files, trigger agents, review results, handle integration, manage dependencies.
+
+---
+
+## 1. Core File Selection Strategy
+
+**Target ONLY Core Files**: Coordinators identify core files (production code), agents handle related tests/mocks atomically.
+
+**File Analysis Commands**:
+```bash
+# Find CORE files with no JS/JSX dependencies (exclude tests/mocks) - SIZE PRIORITIZED
+find superset-frontend/src -name "*.js" -o -name "*.jsx" | grep -v "test\|spec\|mock" | xargs wc -l | sort -n | head -20
+
+# Alternative: Get file sizes in lines with paths
+find superset-frontend/src -name "*.js" -o -name "*.jsx" | grep -v "test\|spec\|mock" | while read file; do
+  lines=$(wc -l < "$file")
+  echo "$lines $file"
+done | sort -n | head -20
+
+# Check dependencies for core files only (start with smallest)
+for file in <core-files-sorted-by-size>; do
+  echo "=== $file ($(wc -l < "$file") lines) ==="
+  grep -E "from '\.\./.*\.jsx?'|from '\./.*\.jsx?'|from 'src/.*\.jsx?'" "$file" || echo "✅ LEAF CANDIDATE"
+done
+
+# Identify heavily imported files (migrate last)  
+grep -r "from.*utils/common" superset-frontend/src/ | wc -l
+
+# Quick leaf analysis with size priority
+find superset-frontend/src -name "*.js" -o -name "*.jsx" | grep -v "test\|spec\|mock" | head -30 | while read file; do
+  deps=$(grep -E "from '\.\./.*\.jsx?'|from '\./.*\.jsx?'|from 'src/.*\.jsx?'" "$file" | wc -l)
+  lines=$(wc -l < "$file")
+  if [ "$deps" -eq 0 ]; then
+    echo "✅ LEAF: $lines lines - $file"
+  fi
+done | sort -n
+```
+
+**Priority Order** (Smallest files first for easier wins):
+1. **Small leaf files** (<50 lines) - No JS/JSX imports, quick TypeScript conversion
+2. **Medium leaf files** (50-200 lines) - Self-contained utilities and helpers  
+3. **Small dependency files** (<100 lines) - Import only already-migrated files
+4. **Larger components** (200+ lines) - Complex but well-contained functionality
+5. **Core foundational files** (utils/common.js, controls.jsx) - migrate last regardless of size
+
+**Size-First Benefits**:
+- Faster completion builds momentum
+- Earlier validation of migration patterns
+- Easier rollback if issues arise
+- Better success rate for agent learning
+
+**Migration Unit**: Each agent call migrates:
+- 1 core file (primary target)
+- All related `*.test.js/jsx` files
+- All related `*.mock.js` files  
+- All related `__mocks__/` files
+
+---
+
+## 2. Task Creation & Agent Control
+
+### Task Triggering
+When triggering the `/js-to-ts` command:
+- **Task Title**: Use the core filename as the task title (e.g., "DebouncedMessageQueue.js migration", "hostNamesConfig.js migration")
+- **Task Description**: Include the full relative path to help agent locate the file
+- **Reference**: Point agent to [AGENT.md](./AGENT.md) for technical instructions
+
+### Post-Processing Workflow
+After each agent completes:
+
+1. **Review Agent Report**: Always read and analyze the complete agent report
+2. **Share Summary**: Provide user with key highlights from agent's work:
+   - Files migrated (core + tests/mocks)
+   - Types created or improved
+   - Any validation issues or coordinator actions needed
+3. **Quality Assessment**: Evaluate agent's TypeScript implementation against criteria:
+   - ✅ **Type Usage**: Proper types used, no `any` types
+   - ✅ **Type Filing**: Types placed in correct hierarchy (component → feature → domain → global)
+   - ✅ **Side Effects**: No unintended changes to other files
+   - ✅ **Import Alignment**: Proper .ts/.tsx import extensions
+4. **Integration Decision**:
+   - **COMMIT**: If agent work is complete and high quality
+   - **FIX & COMMIT**: If minor issues need coordinator fixes
+   - **ROLLBACK**: If major issues require complete rework
+5. **Next Action**: Ask user preference - commit this work or trigger next migration
+
+---
+
+## 3. Integration Decision Framework
+
+**Automatic Integration** ✅:
+- `npm run type` passes without errors
+- Agent created clean TypeScript with proper types
+- Types appropriately filed in hierarchy
+
+**Coordinator Integration** (Fix Side-Effects) 🔧:
+- `npm run type` fails BUT agent's work is high quality
+- Good type usage, proper patterns, well-organized
+- Side-effects are manageable TypeScript compilation errors
+- **Coordinator Action**: Integrate the change, then fix global compilation issues
+
+**Rollback Only** ❌:
+- Agent introduced `any` types or poor type choices
+- Types poorly organized or conflicting with existing patterns
+- Fundamental approach issues requiring complete rework
+
+**Integration Process**:
+1. **Review**: Agent already used `git mv` to preserve history
+2. **Fix Side-Effects**: Update dependent files with proper import extensions
+3. **Resolve Types**: Fix any cascading type issues across codebase
+4. **Validate**: Ensure `npm run type` passes after fixes
+
+---
+
+## 4. Common Integration Patterns
+
+**Common Side-Effects (Expect These)**:
+- **Type import conflicts**: Multiple definitions of same type name
+- **Mock object typing**: Tests need complete type satisfaction
+- **Stub method references**: Use stub vars instead of original methods
+
+**Coordinator Fixes (Standard Process)**:
+1. **Import Resolution**:
+   ```bash
+   # Find authoritative type source
+   grep -r "TypeName" src/*/types.ts
+   # Import from domain types (src/dashboard/types.ts) not component types
+   ```
+
+2. **Test Mock Completion**:
+   ```typescript
+   // Use Partial<T> as T pattern for minimal mocking
+   const mockDashboard: Partial<DashboardInfo> as DashboardInfo = {
+     id: 123,
+     json_metadata: '{}',
+   };
+   ```
+
+3. **Stub Reference Fixes**:
+   ```typescript
+   // ✅ Use stub variable
+   expect(postStub.callCount).toBe(1);
+   // ❌ Don't use original method
+   expect(SupersetClient.post.callCount).toBe(1);
+   ```
+
+4. **Validation Commands**:
+   ```bash
+   npm run type          # TypeScript compilation
+   npm test -- filename  # Test functionality
+   git status           # Should show rename, not add/delete
+   ```
+
+---
+
+## 5. File Categories for Planning
+
+### Leaf Files (Start Here)
+**Self-contained files with minimal JS/JSX dependencies**:
+- Test files (80 files) - Usually only import the file being tested
+- Utility files without internal dependencies
+- Components importing only external libraries
+
+### Heavily Imported Files (Migrate Last)
+**Core files that many others depend on**:
+- `utils/common.js` - Core utility functions
+- `utils/reducerUtils.js` - Redux helpers  
+- `@superset-ui/core` equivalent files
+- Major state management files (`explore/store.js`, `dashboard/actions/`)
+
+### Complex Components (Middle Priority)  
+**Large files requiring careful type analysis**:
+- `components/Datasource/DatasourceEditor.jsx` (1,809 lines)
+- `explore/components/controls/AnnotationLayerControl/AnnotationLayer.jsx` (1,031 lines)
+- `explore/components/ExploreViewContainer/index.jsx` (911 lines)
+
+---
+
+## 6. Success Metrics & Continuous Improvement
+
+**Per-File Gates**:
+- ✅ `npm run type` passes after each migration
+- ✅ Zero `any` types introduced
+- ✅ All imports properly typed
+- ✅ Types filed in correct hierarchy
+
+**Linear Scheduling**:
+When agents report `DEPENDENCY_BLOCK`:
+- Queue dependencies in linear order
+- Process one file at a time to avoid conflicts
+- Handle cascading type changes between files
+
+**After Each Migration**:
+1. **Update guides** with new patterns discovered
+2. **Document coordinator fixes** that become common
+3. **Enhance agent instructions** based on recurring issues
+4. **Track success metrics** - automatic vs coordinator integration rates

+# JavaScript to TypeScript Migration Project
+
+Progressive migration of 219 JS/JSX files to TypeScript in Apache Superset frontend.
+
+## 📁 Project Documentation
+
+- **[AGENT.md](./AGENT.md)** - Complete technical migration guide for agents (includes type reference, patterns, validation)
+- **[COORDINATOR.md](./COORDINATOR.md)** - Strategic workflow for coordinators (file selection, task management, integration)
+
+## 🎯 Quick Start
+
+**For Agents:** Read [AGENT.md](./AGENT.md) for complete migration instructions
+**For Coordinators:** Read [COORDINATOR.md](./COORDINATOR.md) for workflow and [AGENT.md](./AGENT.md) for supervision
+
+**Command:** `/js-to-ts <filename>` - See [../../commands/js-to-ts.md](../../commands/js-to-ts.md)
+
+## 📊 Migration Progress
+
+**Scope**: 219 files total (112 JS + 107 JSX)
+- Production files: 139 (63%)  
+- Test files: 80 (37%)
+
+**Strategy**: Leaf-first migration with dependency-aware coordination
+
+### Completed Migrations ✅
+
+1. **roundDecimal** - `plugins/legacy-plugin-chart-map-box/src/utils/roundDecimal.js`
+   - Migrated core + test files
+   - Added proper TypeScript function signature with optional precision parameter
+   - All tests pass
+
+2. **timeGrainSqlaAnimationOverrides** - `src/explore/controlPanels/timeGrainSqlaAnimationOverrides.js`
+   - Migrated to TypeScript with ControlPanelState and Dataset types
+   - Added TimeGrainOverrideState interface for return type
+   - Used type guards for safe property access
+
+3. **DebouncedMessageQueue** - `src/utils/DebouncedMessageQueue.js`
+   - Migrated to TypeScript with proper generics
+   - Created DebouncedMessageQueueOptions interface
+   - **CREATED test file** with 4 comprehensive test cases
+   - Excellent class property typing with private/readonly modifiers
+
+**Files Migrated**: 3/219 (1.4%)
+**Tests Created**: 2 (roundDecimal had existing, DebouncedMessageQueue created)
+
+### Next Candidates (Leaf Nodes) 🎯
+
+**Identified leaf files with no JS/JSX dependencies:**
+- `src/utils/hostNamesConfig.js` - Domain configuration utility
+- `src/explore/controlPanels/Separator.js` - Control panel configuration  
+- `src/middleware/loggerMiddleware.js` - Logging middleware
+
+**Migration Quality**: All completed migrations have:
+- ✅ Zero `any` types
+- ✅ Proper TypeScript compilation
+- ✅ ESLint validation passed
+- ✅ Test coverage (created where missing)
+
+---
+
+## 📈 Success Metrics
+
+**Per-File Gates**:
+- ✅ `npm run type` passes after each migration
+- ✅ Zero `any` types introduced  
+- ✅ All imports properly typed
+- ✅ Types filed in correct hierarchy
+
+**Overall Progress**:
+- **Automatic Integration Rate**: 100% (3/3 migrations required no coordinator fixes)
+- **Test Coverage**: Improved (1 new test file created)
+- **Type Safety**: Enhanced with proper interfaces and generics

+
+**When creating pull requests:**
+
+1. **Read the current PR template**: Always check `.github/PULL_REQUEST_TEMPLATE.md` for the latest format
+2. **Use the template sections**: Include all sections from the template (SUMMARY, BEFORE/AFTER, TESTING INSTRUCTIONS, ADDITIONAL INFORMATION)
+3. **Follow PR title conventions**: Use [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/)
+   - Format: `type(scope): description`
+   - Example: `fix(dashboard): load charts correctly`
+   - Types: `fix`, `feat`, `docs`, `style`, `refactor`, `perf`, `test`, `chore`
+
+**Important**: Always reference the actual template file at `.github/PULL_REQUEST_TEMPLATE.md` instead of using cached content, as the template may be updated over time.
+
 ## Pre-commit Validation
 
 **Use pre-commit hooks for quality validation:**

+
+# Superset Frontend Linting Architecture
+
+## Overview
+We use a hybrid linting approach combining OXC (fast, standard rules) with custom AST-based checks for Superset-specific patterns.
+
+## Components
+
+### 1. Primary Linter: OXC
+- **What**: Oxidation Compiler's linter (oxlint)
+- **Handles**: 95% of linting rules (standard ESLint rules, TypeScript, React, etc.)
+- **Speed**: ~50-100x faster than ESLint
+- **Config**: `oxlint.json`
+
+### 2. Custom Rule Checker
+- **What**: Node.js AST-based script
+- **Handles**: Superset-specific rules:
+  - No literal colors (use theme)
+  - No FontAwesome icons (use Icons component)
+  - No template vars in i18n
+- **Speed**: Fast enough for pre-commit
+- **Script**: `scripts/check-custom-rules.js`
+
+## Developer Workflow
+
+### Local Development
+```bash
+# Fast linting (OXC only)
+npm run lint
+
+# Full linting (OXC + custom rules)
+npm run lint:full
+
+# Auto-fix what's possible
+npm run lint-fix
+```
+
+### Pre-commit
+1. OXC runs first (via `scripts/oxlint.sh`)
+2. Custom rules check runs second (lightweight, AST-based)
+3. Both must pass for commit to succeed
+
+### CI Pipeline
+```yaml
+- name: Lint with OXC
+  run: npm run lint
+
+- name: Check custom rules
+  run: npm run check:custom-rules
+```
+
+## Why This Architecture?
+
+### ✅ Pros
+1. **No binary distribution issues** - ASF compatible
+2. **Fast performance** - OXC for bulk, lightweight script for custom
+3. **Maintainable** - Custom rules in JavaScript, not Rust
+4. **Flexible** - Can evolve as OXC adds plugin support
+5. **Cacheable** - Both OXC and Node.js are standard tools
+
+### ❌ Cons  
+1. **Two tools** - Slightly more complex than single linter
+2. **Duplicate parsing** - Files parsed twice (once by each tool)
+
+### 🔄 Migration Path
+When OXC supports JavaScript plugins:
+1. Convert `check-custom-rules.js` to OXC plugin format
+2. Consolidate back to single tool
+3. Keep same rules and developer experience
+
+## Implementation Checklist
+

+- [x] Pre-commit integration  
+- [ ] Custom rules script
+- [ ] Combine in npm scripts
+- [ ] Update CI pipeline
+- [ ] Developer documentation
+
+## Performance Targets
+
+| Operation | Target Time | Current |
+|-----------|------------|---------|
+| Pre-commit (changed files) | <2s | ✅ 1.5s |
+| Full lint (all files) | <10s | ✅ 8s |
+| Custom rules check | <5s | 🔄 TBD |
+
+## Caching Strategy
+
+### Local Development
+- OXC: Built-in incremental checking
+- Custom rules: Use file hash cache (similar to pytest cache)
+
+### CI
+- Cache `node_modules` (includes oxlint binary)
+- Cache custom rules results by commit hash
+- Skip unchanged files using git diff
+
+## Future Improvements
+
+1. **When OXC adds plugin support**: Migrate custom rules to OXC plugins
+2. **Consider Biome**: Another Rust-based linter with plugin support
+3. **AST sharing**: Investigate sharing AST between tools to avoid double parsing

 ## Next
+
+### MCP Service
+
+The MCP (Model Context Protocol) service enables AI assistants and automation tools to interact programmatically with Superset.
+
+#### New Features
+- MCP service infrastructure with FastMCP framework
+- Tools for dashboards, charts, datasets, SQL Lab, and instance metadata
+- Optional dependency: install with `pip install apache-superset[fastmcp]`
+- Runs as separate process from Superset web server
+- JWT-based authentication for production deployments
+
+#### New Configuration Options
+
+**Development** (single-user, local testing):
+```python
+# superset_config.py
+MCP_DEV_USERNAME = "admin"  # User for MCP authentication
+MCP_SERVICE_HOST = "localhost"
+MCP_SERVICE_PORT = 5008
+```
+
+**Production** (JWT-based, multi-user):
+```python
+# superset_config.py
+MCP_AUTH_ENABLED = True
+MCP_JWT_ISSUER = "https://your-auth-provider.com"
+MCP_JWT_AUDIENCE = "superset-mcp"
+MCP_JWT_ALGORITHM = "RS256"  # or "HS256" for shared secrets
+
+# Option 1: Use JWKS endpoint (recommended for RS256)
+MCP_JWKS_URI = "https://auth.example.com/.well-known/jwks.json"
+
+# Option 2: Use static public key (RS256)
+MCP_JWT_PUBLIC_KEY = "-----BEGIN PUBLIC KEY-----..."
+
+# Option 3: Use shared secret (HS256)
+MCP_JWT_ALGORITHM = "HS256"
+MCP_JWT_SECRET = "your-shared-secret-key"
+
+# Optional overrides
+MCP_SERVICE_HOST = "0.0.0.0"
+MCP_SERVICE_PORT = 5008
+MCP_SESSION_CONFIG = {
+    "SESSION_COOKIE_SECURE": True,
+    "SESSION_COOKIE_HTTPONLY": True,
+    "SESSION_COOKIE_SAMESITE": "Strict",
+}
+```
+
+#### Running the MCP Service
+
+```bash
+# Development
+superset mcp run --port 5008 --debug
+
+# Production
+superset mcp run --port 5008
+
+# With factory config
+superset mcp run --port 5008 --use-factory-config
+```
+
+#### Deployment Considerations
+
+The MCP service runs as a **separate process** from the Superset web server.
+
+**Important**:
+- Requires same Python environment and configuration as Superset
+- Shares database connections with main Superset app
+- Can be scaled independently from web server
+- Requires `fastmcp` package (optional dependency)
+
+**Installation**:
+```bash
+# Install with MCP support
+pip install apache-superset[fastmcp]
+
+# Or add to requirements.txt
+apache-superset[fastmcp]>=X.Y.Z
+```
+
+**Process Management**:
+Use systemd, supervisord, or Kubernetes to manage the MCP service process.
+See `superset/mcp_service/PRODUCTION.md` for deployment guides.
+
+**Security**:
+- Development: Uses `MCP_DEV_USERNAME` for single-user access
+- Production: **MUST** configure JWT authentication
+- See `superset/mcp_service/SECURITY.md` for details
+
+#### Documentation
+
+- Architecture: `superset/mcp_service/ARCHITECTURE.md`
+- Security: `superset/mcp_service/SECURITY.md`
+- Production: `superset/mcp_service/PRODUCTION.md`
+- Developer Guide: `superset/mcp_service/CLAUDE.md`
+- Quick Start: `superset/mcp_service/README.md`
+
+---
+
+- [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.
@@ -30,8 +142,9 @@ assists people when migrating to a new version.
 - [33116](https://github.com/apache/superset/pull/33116) In Echarts Series charts (e.g. Line, Area, Bar, etc.) charts, the `x_axis_sort_series` and `x_axis_sort_series_ascending` form data items have been renamed with `x_axis_sort` and `x_axis_sort_asc`.
   There's a migration added that can potentially affect a significant number of existing charts.
 - [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.

+# Lightweight docker-compose for running multiple Superset instances
+# This includes only essential services: database and Superset app (no Redis)
+#
+# 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:
+# - 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.
+#
+# 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
+#   docker-compose -f docker-compose-light.yml run --rm pytest-runner pytest --collect-only
+#
+# 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)
+# - Set SUPERSET_LOG_LEVEL=debug in docker/.env-local for detailed logs

 ### Local overrides
 
+#### Environment Variables
+
+To override environment variables locally, create a `./docker/.env-local` file (git-ignored). This file will be loaded after `.env` and can override any settings.
+
+#### Python Configuration
+
 In order to override configuration settings locally, simply make a copy of [`./docker/pythonpath_dev/superset_config_local.example`](./pythonpath_dev/superset_config_local.example)
-into `./docker/pythonpath_dev/superset_config_docker.py` (git ignored) and fill in your overrides.
+into `./docker/pythonpath_dev/superset_config_docker.py` (git-ignored) and fill in your overrides.
+
+#### WebSocket Configuration
+
+To customize the WebSocket server configuration, create `./docker/superset-websocket/config.json` (git-ignored) based on [`./docker/superset-websocket/config.example.json`](./superset-websocket/config.example.json).
+
+Then update the `superset-websocket`.`volumes` config to mount it.
+
+#### Docker Compose Overrides
+
+For advanced Docker Compose customization, create a `docker-compose-override.yml` file (git-ignored) to override or extend services without modifying the main compose file.
