+
+## JavaScript to TypeScript Conversion
+
+### General Principles
+
+**Goal:** Convert JavaScript files to TypeScript while maintaining 100% functional compatibility and zero runtime behavior changes.
+
+**Key Rules:**
+
+- Keep class-based components as class-based (don't convert to functional)
+- Keep functional components as functional (don't convert to class-based)
+- Look for existing TypeScript types in the codebase before creating new ones
+- Remove PropTypes in favor of TypeScript interfaces
+- Commit and push regularly to avoid losing work
+
+### Conversion Process
+
+#### 1. Preparation
+
+```bash
+# Find all JavaScript files to convert
+find packages/libs/PACKAGE/src -name "*.js" -o -name "*.jsx"
+
+# Check for existing types
+grep -r "interface\|type" packages/libs/PACKAGE/src --include="*.ts" --include="*.d.ts"
+```
+
+#### 2. File-by-File Conversion
+
+**For each JavaScript file:**
+
+1. **Read the file** to understand its structure
+2. **Identify dependencies** and their types
+3. **Rename the file** using `git mv` to preserve history:
+
+   ```bash
+   # For JSX files
+   git mv Component.jsx Component.tsx
+
+   # For plain JavaScript files
+   git mv utility.js utility.ts
+   ```
+
+4. **Update the file** with proper TypeScript types:
+   - Import types from existing TypeScript files where available
+   - Create interfaces for component props and state
+   - Add type annotations to function parameters and return values
+   - Remove PropTypes imports and definitions
+5. **Verify compilation** (see Testing and Verification section below)
+
+**Important:** Always use `git mv` instead of renaming files manually. This preserves git history and makes it easier to track changes across the rename.
+
+#### 3. Handling Common Patterns
+
+**React Components:**
+
+```typescript
+// Class component
+interface MyComponentProps {
+  value: string;
+  onChange: (value: string) => void;
+}
+
+interface MyComponentState {
+  isExpanded: boolean;
+}
+
+class MyComponent extends React.Component<MyComponentProps, MyComponentState> {
+  constructor(props: MyComponentProps) {
+    super(props);
+    this.state = { isExpanded: false };
+  }
+}
+```
+
+**Functional Components:**
+
+```typescript
+interface MyFunctionProps {
+  value: string;
+  onChange: (value: string) => void;
+}
+
+const MyFunction: React.FC<MyFunctionProps> = ({ value, onChange }) => {
+  // implementation
+};
+```
+
+**Generic Components:**
+
+```typescript
+// For components that work with different data types
+interface TableProps<Row> {
+  rows: Row[];
+  columns: Column<Row>[];
+}
+
+class Table<Row> extends React.Component<TableProps<Row>> {
+  // implementation
+}
+```
+
+#### 4. PropTypes Migration
+
+**Before (JavaScript):**
+
+```javascript
+import PropTypes from 'prop-types';
+
+MyComponent.propTypes = {
+  value: PropTypes.string.isRequired,
+  onChange: PropTypes.func.isRequired,
+  optional: PropTypes.number,
+};
+```
+
+**After (TypeScript):**
+
+```typescript
+interface MyComponentProps {
+  value: string;
+  onChange: (value: string) => void;
+  optional?: number;
+}
+```
+
+### Common Type Imports
+
+**WDK Model Types:**
+
+```typescript
+import {
+  RecordClass,
+  RecordInstance,
+  Question,
+  AttributeField,
+  AttributeValue,
+  LinkAttributeValue,
+  TableField,
+} from '../Utils/WdkModel';
+```
+
+**Mesa Types:**
+
+```typescript
+import type {
+  MesaColumn,
+  MesaStateProps,
+} from '@veupathdb/coreui/lib/components/Mesa/types';
+```
+
+**Category/Ontology Types:**
+
+```typescript
+import {
+  CategoryTreeNode,
+  IndividualNode,
+  CategoryNode,
+  isIndividual,
+} from '../Utils/CategoryUtils';
+```
+
+---
+
+## Reducing Unsafe Type Assertions
+
+### Philosophy
+
+Treat `as` as a last resort. The goal is to have TypeScript infer correct types through proper type annotations, not to force types through assertions.
+
+### Decision Tree for Each `as Something`
+
+```
+1. Can I fix types at the source?
+   ├─ Yes → Add/improve type annotations, generics, discriminated unions
+   └─ No → Continue to 2
+
+2. Is this from untyped/poorly typed code (3rd-party, JSON, DOM)?
+   ├─ Yes → Use runtime checks + type guards
+   └─ No → Continue to 3
+
+3. Is this an allowed case?
+   ├─ Yes (unknown/any boundary, DOM, 3rd-party) → Keep but minimize scope
+   └─ No → Must refactor to remove
+```
+
+### Fix Types at the Source
+
+**❌ Bad: Using `as` to work around poor types**
+
+```typescript
+const result = myFunc() as MyType;
+```
+
+**✅ Good: Add proper return type to function**
+
+```typescript
+function myFunc(): MyType {
+  // implementation
+}
+const result = myFunc(); // Type inferred correctly
+```
+
+**❌ Bad: Casting array initialization**
+
+```typescript
+const items = [] as MyType[];
+```
+
+**✅ Good: Use generic type parameter**
+
+```typescript
+// Option 1: Type annotation
+const items: MyType[] = [];
+
+// Option 2: Generic reduce
+array.reduce<MyType[]>((acc, item) => {
+  // ...
+}, []);
+```
+
+**❌ Bad: Asserting object literals**
+
+```typescript
+const config = {
+  name: 'test',
+  value: 42,
+} as Config;
+```
+
+**✅ Good: Use `satisfies` for validation**
+
+```typescript
+const config = {
+  name: 'test',
+  value: 42,
+} satisfies Config;
+```
+
+### Use Runtime Checks and Type Guards
+
+**❌ Bad: Blind assertion**
+
+```typescript
+const value = data.value as string;
+```
+
+**✅ Good: Runtime check first**
+
+```typescript
+const value = typeof data.value === 'string' ? data.value : '';
+```
+
+**❌ Bad: Assuming property exists**
+
+```typescript
+const text = (obj as any).displayText;
+```
+
+**✅ Good: Type guard with proper checks**
+
+```typescript
+const text =
+  typeof obj === 'object' && obj !== null && 'displayText' in obj
+    ? (obj as { displayText: string }).displayText
+    : '';
+```
+
+**✅ Better: Use proper type from WdkModel**
+
+```typescript
+import { LinkAttributeValue } from '../Utils/WdkModel';
+
+const text =
+  typeof obj === 'object' && obj !== null && 'displayText' in obj
+    ? (obj as LinkAttributeValue).displayText
+    : '';
+```
+
+### Allowed `as` Cases
+
+**1. Casting from `unknown` or `any` at boundaries (after runtime checks)**
+
+```typescript
+function parseData(json: unknown): MyData {
+  // Runtime validation
+  if (typeof json !== 'object' || json === null) {
+    throw new Error('Invalid data');
+  }
+  // Now safe to assert
+  return json as MyData;
+}
+```
+
+**2. DOM interactions with specific element types**
+
+```typescript
+const button = document.getElementById('myButton') as HTMLButtonElement;
+// Acceptable if you know the element exists and is a button
+```
+
+**3. Third-party libraries without accurate typings**
+
+```typescript
+// Wrap in a small helper rather than scattering assertions
+function safeLibCall(input: string): MyType {
+  return poorlyTypedLib.method(input) as MyType;
+}
+```
+
+**4. Non-null assertions after explicit checks**
+
+```typescript
+if (!map.has(key)) {
+  map.set(key, []);
+}
+const array = map.get(key)!; // Safe - we just set it
+```
+
+### Common Patterns to Improve
+
+**Pattern: Discriminated Unions**
+
+❌ Bad:
+
+```typescript
+type Filter = MemberFilter | RangeFilter | MultiFilter;
+
+function process(filter: Filter) {
+  if ((filter.value as MultiFilterValue).filters) {
+    // use as MultiFilter
+  }
+}
+```
+
+✅ Good:
+
+```typescript
+type Filter =
+  | { type: 'member'; value: MemberValue }
+  | { type: 'range'; value: RangeValue }
+  | { type: 'multi'; value: MultiFilterValue };
+
+function process(filter: Filter) {
+  if (filter.type === 'multi') {
+    // TypeScript knows filter.value is MultiFilterValue
+    filter.value.filters.forEach(/* ... */);
+  }
+}
+```
+
+**Pattern: Generic Reduce**
+
+❌ Bad:
+
+```typescript
+const result = items.reduce((acc, item) => {
+  return { ...acc, [item.id]: item };
+}, {} as Record<string, Item>);
+```
+
+✅ Good:
+
+```typescript
+const result = items.reduce<Record<string, Item>>((acc, item) => {
+  return { ...acc, [item.id]: item };
+}, {});
+```
+
+---
+
+## Common Patterns in This Codebase
+
+### Mesa Component Pattern
+
+Mesa is now fully TypeScript with generic types. Use them!
+
+**✅ Correct Mesa Usage:**
+
+```typescript
+import { Mesa } from '@veupathdb/coreui/lib/components/Mesa';
+import type {
+  MesaColumn,
+  MesaStateProps,
+} from '@veupathdb/coreui/lib/components/Mesa/types';
+
+// Define your row type
+type MyRow = {
+  id: string;
+  name: string;
+  value: number;
+};
+
+// Create properly typed state
+const tableState: MesaStateProps<MyRow, string> = {
+  rows: myRows,
+  columns: myColumns as MesaColumn<MyRow, string>[],
+  eventHandlers: {
+    onSort: (column: MesaColumn<MyRow>, direction: string) => {
+      // TypeScript knows column.key is string
+    },
+  },
+  uiState: {
+    sort: {
+      columnKey: sortColumn,
+      direction: 'asc' as 'asc' | 'desc',
+    },
+  },
+  options: {
+    toolbar: true,
+  },
+};
+
+// Use without assertion
+<Mesa state={tableState} />;
+```
+
+### WDK Model Pattern
+
+**Attribute Values:**
+
+```typescript
+import { AttributeValue, LinkAttributeValue } from '../Utils/WdkModel';
+
+// AttributeValue is: string | LinkAttributeValue | null
+
+function renderValue(value: AttributeValue) {
+  if (typeof value === 'object' && value !== null && 'displayText' in value) {
+    // TypeScript knows this is LinkAttributeValue
+    return <a href={value.url}>{value.displayText}</a>;
+  }
+  // TypeScript knows this is string | null
+  return value;
+}
+```
+
+### Category Tree Pattern
+
+**Use type guards:**
+
+```typescript
+import {
+  CategoryTreeNode,
+  IndividualNode,
+  isIndividual,
+} from '../Utils/CategoryUtils';
+
+function processNode(node: CategoryTreeNode) {
+  if (isIndividual(node)) {
+    // TypeScript knows node is IndividualNode
+    const ref = node.wdkReference;
+    // ...
+  }
+}
+```
+
+### HOC Wrapping Pattern
+
+Higher-order components often need assertions. This is acceptable:
+
+```typescript
+import { wrappable, pure } from '../Utils/ComponentUtils';
+
+export default wrappable(pure(MyComponent as any));
+// Acceptable - HOC typing is complex and architectural
+```
+
+### Props Spreading Pattern
+
+When spreading props to components with different interfaces:
+
+```typescript
+// If the interfaces genuinely differ, assertion may be needed
+<ChildComponent {...(props as ChildComponentProps)} />
+
+// But prefer explicit prop passing when possible
+<ChildComponent
+  prop1={props.prop1}
+  prop2={props.prop2}
+/>
+```
+
+---
+
+## Specific Component Guidelines
+
+### Converting Mesa Components
+
+Mesa components use generics extensively. When converting:
+
+1. **Identify the Row type** - what data is being displayed?
+2. **Identify the Key type** - usually `string` for column keys
+3. **Use generic parameters** everywhere:
+
+   ```typescript
+   interface MyComponentProps<Row> extends MesaStateProps<Row> {
+     extraProp: string;
+   }
+
+   class MyComponent<Row> extends Component<MyComponentProps<Row>> {
+     // ...
+   }
+   ```
+
+### Converting Record Components
+
+Record components work with WDK model types:
+
+```typescript
+import {
+  RecordClass,
+  RecordInstance,
+  AttributeField,
+  TableField,
+} from '../Utils/WdkModel';
+
+interface RecordComponentProps {
+  record: RecordInstance;
+  recordClass: RecordClass;
+  attributes: AttributeField[];
+  tables: TableField[];
+}
+```
+
+### Converting Form Components
+
+Form components often have complex event handlers:
+
+```typescript
+interface FormProps {
+  value: FormData;
+  onChange: (value: FormData) => void;
+  onSubmit: (value: FormData) => Promise<void>;
+}
+
+class Form extends Component<FormProps> {
+  handleChange = (field: string) => (value: string) => {
+    this.props.onChange({
+      ...this.props.value,
+      [field]: value,
+    });
+  };
+
+  handleSubmit = async (e: React.FormEvent) => {
+    e.preventDefault();
+    await this.props.onSubmit(this.props.value);
+  };
+}
+```
+
+---
+
+## Testing and Verification
+
+### Before Committing
+
+**1. Install Dependencies (first time only):**
+
+```bash
+# Download and install all dependencies (can take a few minutes)
+yarn
+```
+
+**2. Build and Verify TypeScript Compilation:**
+
+```bash
+# Build wdk-client and its dependencies (cached if no changes)
+yarn nx build-npm-modules @veupathdb/wdk-client
+
+# Or, if dependencies are already built, build just wdk-client:
+yarn workspace @veupathdb/wdk-client build-npm-modules
+```
+
+Must complete successfully with no errors.
+
+**3. Check for Remaining Issues:**
+
+```bash
+# Count 'as any' assertions
+grep -r "as any" packages/libs/PACKAGE/src --include="*.ts" --include="*.tsx" | wc -l
+
+# Find files with most assertions
+grep -r " as " packages/libs/PACKAGE/src --include="*.ts" --include="*.tsx" | \
+  grep -v "as const" | cut -d: -f1 | sort | uniq -c | sort -rn | head -20
+```
+
+**3. Runtime Testing:**
+
+- If possible, run the application and test affected features
+- Check browser console for errors
+- Verify no new warnings
+
+### Commit Strategy
+
+**Commit frequently with clear messages:**
+
+```bash
+# Good commit messages
+git commit -m "Convert Mesa Utils to TypeScript (6 files)"
+git commit -m "Fix TypeScript errors in RecordTable (batch 1/3)"
+git commit -m "Reduce 'as any' assertions in Answer components"
+git commit -m "Improve type safety in Operations.tsx using generics"
+```
+
+**Batch related changes:**
+
+- Group by component/feature area
+- Keep commits focused and atomic
+- Push regularly to avoid losing work
+

+
+## Quick Reference
+
+### Type Import Locations
+
+| Type                                        | Import Path                                   |
+| ------------------------------------------- | --------------------------------------------- |
+| `RecordClass`, `Question`, `AttributeField` | `../Utils/WdkModel`                           |
+| `MesaColumn`, `MesaStateProps`              | `@veupathdb/coreui/lib/components/Mesa/types` |
+| `CategoryTreeNode`, `isIndividual`          | `../Utils/CategoryUtils`                      |
+| `Step`, `StrategyDetails`                   | `../Utils/WdkUser`                            |
+
+### Common TypeScript Patterns
+
+```typescript
+// Generic reduce
+array.reduce<ResultType>((acc, item) => { ... }, initialValue)
+
+// Type guard
+function isType(obj: unknown): obj is MyType {
+  return typeof obj === 'object' && obj !== null && 'property' in obj;
+}
+
+// Discriminated union
+type Result =
+  | { success: true; data: Data }
+  | { success: false; error: Error };
+
+// Non-null assertion (after check)
+if (map.has(key)) {
+  const value = map.get(key)!;
+}
+
+// Satisfies (validation without widening)
+const config = { ... } satisfies Config;
+
+// Optional chaining + nullish coalescing
+const value = obj?.property?.nested ?? defaultValue;
+```
+
+---
+
+## Trust Usage Patterns Over Type Definitions
+
+### Critical Principle
+
+**The implementation is the source of truth, not the types.**
+
+When reviewing JS→TS conversions, **always trust the original JavaScript usage patterns** over any existing TypeScript type definitions. Type definitions can be incorrect due to:
+
+1. **Human error** when types were first written
+2. **Stale types** that weren't updated when the implementation changed
+3. **Incorrect assumptions** during previous conversion attempts
+4. **Copy-paste errors** from similar but different APIs
+
+### Verification Process
+
+When you encounter a type definition that seems questionable:
+
+1. **Find the original JavaScript implementation:**
+
+   ```bash
+   # Check git history for the original .js/.jsx file
+   git log --all --follow --format="%H %s" -- "**/ComponentName.*"
+   git show <commit>^:path/to/file.jsx
+   ```
+
+2. **Search for actual usage in the codebase:**
+
+   ```bash
+   # Find all consumers of the API
+   grep -r "functionName\|ComponentName" packages/ --include="*.js" --include="*.jsx" --include="*.ts" --include="*.tsx"
+   ```
+
+3. **Compare implementations across time:**
+   ```bash
+   # View the diff between original JS and current TS
+   git diff <js-commit> HEAD -- path/to/file
+   ```
+
+### Red Flags Indicating Type Problems
+
+Watch for these warning signs:
+
+- **Comments questioning types**: "NOTE: the typing of X seems wrong..."
+- **Workarounds with type assertions**: `as unknown as SomeType`
+- **Unused APIs**: If no one uses a function, the type might be wrong
+- **Defensive code**: Logic working around "incorrect" types
+- **Multiple consumers using assertions**: All callers need `as` to use it
+
+### Case Study: Mesa Component API Bugs
+
+During careful review of the Mesa TS conversion, we found **three significant API bugs** where types didn't match the original JavaScript:
+
+#### Bug 1: `getValue` Parameter Mismatch
+
+**Original JS (correct):**
+
+```javascript
+getValue({ row, key }); // Pass the column key
+```
+
+**Incorrect TS type definition:**
+
+```typescript
+getValue?: (props: { row: Row; index: number }) => Value;  // Wrong: uses index
+```
+
+**How we found it:**
+
+- Checked `git log` for DataCell.jsx
+- Found original always used `{ row, key }`
+- No actual usage in codebase (unused API)
+
+**Fix:**
+
+```typescript
+getValue?: (props: { row: Row; key: Key }) => Value;  // Restored original API
+```
+
+#### Bug 2: `childRow` Breaking Change
+
+**Original JS (correct):**
+
+```javascript
+childRow(rowIndex, row); // Two separate positional arguments
+```
+
+**Incorrect TS conversion:**
+
+```typescript
+childRow({ rowIndex, rowData: row }); // Object argument - BREAKING!
+```
+
+**Evidence of breakage** - Found this workaround in AiExpressionSummary.tsx:
+
+```typescript
+childRow: (badProps) => {
+  // NOTE: the typing of `ChildRowProps` seems wrong
+  // as it is called with two args, not one
+  const rowIndex = badProps as unknown as number;
+  const rowData = topics[rowIndex];
+  // ...
+```
+
+**Fix:**
+
+```typescript
+export type ChildRowFunc<Row> = (rowIndex: number, rowData: Row) => ReactElement;
+childRow?: ChildRowFunc<Row>;
+```
+
+And in DataCell.tsx:
+
+```typescript
+// Before: childRow({ rowIndex, rowData: row })
+// After:  childRow(rowIndex, row)
+```
+
+#### Bug 3: `MesaAction` Swapped Parameters
+
+**Type definition claimed:**
+
+```typescript
+handler?: (selection: Row[], columns, rows) => void;  // "Full selection"
+callback?: (row: Row, columns) => void;               // "Single row"
+```
+
+**Runtime actually did:**
+
+```typescript
+if (typeof handler === 'function')
+  selection.forEach((row) => handler(row, columns)); // Per-row iteration!
+
+if (typeof callback === 'function') callback(selection, columns, rows); // Full selection!
+```
+
+**They were backwards!** The type definition had them swapped.
+
+**Fix:** Corrected the signatures to match actual behavior.
+
+### Lessons Learned
+
+1. **Types can lie** - especially if they predate the implementation
+2. **Check git blame** - see when types vs. implementation were introduced
+3. **Look for workarounds** - they indicate type problems
+4. **Unused code is suspicious** - if nobody uses it, type might be wrong
+5. **Comments are clues** - developers often note when types seem off
+
+### Best Practices for Review
+
+When reviewing a TS conversion:
+
+✅ **DO:**
+
+- Check original .js/.jsx file in git history
+- Search for all consumers of the API
+- Look for type assertions at call sites
+- Read comments questioning the types
+- Verify types match actual runtime behavior
+
+❌ **DON'T:**
+
+- Assume existing .d.ts or types.ts files are correct
+- Trust types without verifying against implementation
+- Ignore comments about "weird" types
+- Accept widespread `as any` usage as necessary
+
+## Lessons Learned from This Session
+
+### What Worked Well
+
+1. **Parallel agent execution** for converting multiple files simultaneously
+2. **Systematic batching** of error fixes (10-15 errors per batch)
+3. **Using generic type parameters** instead of `as` assertions
+4. **Starting with utilities** before components (bottom-up approach)
+5. **Regular commits and pushes** to preserve progress
+6. **Trusting original JavaScript** over questionable TypeScript types
+7. **Following the clues** (comments, workarounds, git history)
+
+### Common Pitfalls to Avoid
+
+1. **Don't skip reading existing type definitions** - they often already exist
+2. **Don't use `as any` as a first resort** - understand why the type doesn't match
+3. **Don't change class/functional component style** during conversion
+4. **Don't batch too many changes** - keep commits focused
+5. **Don't forget to delete old JavaScript files** after conversion
+
+### Key Insights
+
+- **Mesa's type system** is comprehensive - use it rather than fighting it
+- **WDK Model types** are well-defined - import and use them
+- **Runtime checks before assertions** make code safer and more maintainable
+- **Generic type parameters** are almost always better than type assertions
+- **HOC and component spreading** are the main remaining assertion challenges
+
+---
+
+## Future Work Opportunities
+
+### High Priority
+
+- Convert remaining JavaScript in `web-common` packages
+- Improve discriminated union patterns in filter components
+- Add type guards for complex WDK model interactions
+
+### Medium Priority
+
+- Refactor HOC patterns for better typing
+- Create utility type guards for common patterns
+- Document component-specific type patterns
+
+### Low Priority
+
+- Review and improve remaining `as` assertions at boundaries
+- Consider adding runtime validation libraries (e.g., zod, io-ts)
+- Explore stricter TypeScript compiler options
+
+---
+
+## Getting Help
+
+**When stuck on a type issue:**
+
+1. Check this guide for similar patterns
+2. Search the codebase for existing solutions: `grep -r "similar pattern"`
+3. Look at recently converted files for examples
+4. Check TypeScript docs for the specific feature
+5. Consider if the type issue reveals a real bug
