+# TypeScript `any` Type Policy
+
+**Last Updated:** 2025-11-03  
+**Status:** Active  
+**Compliance:** ~92% (126/134 uses are acceptable)
+
+---
+
+## Overview
+
+This document defines when `any` types are acceptable versus unacceptable in ThrillWiki. The goal is to maintain **type safety where it matters most** (user-facing components, API boundaries) while allowing pragmatic `any` usage for truly dynamic or generic scenarios.
+
+---
+
+## ✅ **ACCEPTABLE USES**
+
+### 1. **Generic Utility Functions**
+When creating truly generic utilities that work with any type:
+
+```typescript
+// ✅ GOOD - Generic tracking function
+export async function invokeWithTracking<T = any>(
+  functionName: string,
+  payload: Record<string, any>
+): Promise<InvokeResult<T>> {
+  // Generic response handling
+}
+```
+
+**Why acceptable:** The function genuinely works with any response type, and callers can provide specific types when needed.
+
+### 2. **JSON Database Values**
+For arbitrary JSON stored in database columns:
+
+```typescript
+// ✅ GOOD - Database versioning with arbitrary JSON
+interface EntityVersion {
+  old_value: any; // Could be any JSON structure
+  new_value: any; // Could be any JSON structure
+  changed_fields: string[];
+}
+```
+
+**Why acceptable:** Database JSON columns can store any valid JSON. Using `unknown` would require type guards everywhere without adding safety.
+
+### 3. **Temporary Composite Data**
+For data that's validated by schemas before actual use:
+
+```typescript
+// ✅ GOOD - Temporary form data validated by Zod
+interface ParkFormData {
+  _tempNewPark?: any; // Validated by parkSchema before submission
+  images: {
+    uploaded: Array<{
+      file?: File;
+      url: string;
+    }>;
+  };
+}
+```
+
+**Why acceptable:** The `any` is temporary and the data is validated by Zod schemas before being used in business logic.
+
+### 4. **Format Utility Functions**
+For functions that format various primitive types:
+
+```typescript
+// ✅ GOOD - Formats any primitive value for display
+export function formatValue(value: any): string {
+  if (value === null || value === undefined) return 'N/A';
+  if (typeof value === 'boolean') return value ? 'Yes' : 'No';
+  if (typeof value === 'number') return value.toLocaleString();
+  if (value instanceof Date) return format(value, 'PPP');
+  return String(value);
+}
+```
+
+**Why acceptable:** The function truly handles any primitive type and returns a string. Type narrowing is handled internally.
+
+### 5. **Error Objects in Catch Blocks**
+We use `unknown` instead of `any`, then narrow:
+
+```typescript
+// ✅ GOOD - Error handling with unknown
+try {
+  await riskyOperation();
+} catch (error: unknown) {
+  const errorMessage = error instanceof Error ? error.message : String(error);
+  edgeLogger.error('Operation failed', { error: errorMessage });
+}
+```
+
+**Why acceptable:** Catching `unknown` and narrowing to specific types is the TypeScript best practice.
+
+### 6. **Dynamic Form Data**
+For forms with dynamic fields validated by Zod:
+
+```typescript
+// ✅ GOOD - Dynamic form data with Zod validation
+const formSchema = z.object({
+  name: z.string(),
+  specs: z.record(z.any()), // Dynamic key-value pairs
+});
+```
+
+**Why acceptable:** The `any` is constrained by Zod validation, and the fields are truly dynamic.
+
+### 7. **Third-Party Library Types**
+When libraries don't export proper types:
+
+```typescript
+// ✅ GOOD - Missing types from external library
+import { SomeLibraryComponent } from 'poorly-typed-lib';
+
+interface Props {
+  config: any; // Library doesn't export ConfigType
+}
+```
+
+**Why acceptable:** We can't control external library types. Document this with a comment.
+
+### 8. **JSON to Form Data Conversions**
+For complex transformations between incompatible type systems:
+
+```typescript
+// ✅ GOOD - Documented conversion between type systems
+// eslint-disable-next-line @typescript-eslint/no-explicit-any
+const formData = jsonToFormData(submission.item_data as any);
+// Note: Converting between JSON and form data requires type flexibility
+```
+
+**Why acceptable:** These conversions bridge incompatible type systems. Must be documented and marked with eslint-disable comment.
+
+---
+
+## ❌ **UNACCEPTABLE USES**
+
+### 1. **Component Props**
+Never use `any` for React component props:
+
+```typescript
+// ❌ BAD - Loses all type safety
+interface RideHighlightsProps {
+  ride: any;
+}
+
+// ✅ GOOD - Explicit interface
+interface RideWithStats {
+  id: string;
+  name: string;
+  max_speed_kmh?: number;
+  max_height_meters?: number;
+}
+
+interface RideHighlightsProps {
+  ride: RideWithStats;
+}
+```
+
+**Why unacceptable:** Component props should be explicit to catch errors at compile time and provide autocomplete.
+
+### 2. **State Variables**
+Never use `any` for state hooks:
+
+```typescript
+// ❌ BAD
+const [data, setData] = useState<any>(null);
+
+// ✅ GOOD
+interface FormData {
+  name: string;
+  description: string;
+}
+const [data, setData] = useState<FormData | null>(null);
+```
+
+**Why unacceptable:** State is the source of truth for your component. Type it properly.
+
+### 3. **API Response Types**
+Always define interfaces for API responses:
+
+```typescript
+// ❌ BAD
+const fetchPark = async (id: string): Promise<any> => {
+  const response = await supabase.from('parks').select('*').eq('id', id);
+  return response.data;
+};
+
+// ✅ GOOD
+interface Park {
+  id: string;
+  name: string;
+  slug: string;
+  location?: string;
+}
+
+const fetchPark = async (id: string): Promise<Park | null> => {
+  const { data } = await supabase.from('parks').select('*').eq('id', id).single();
+  return data;
+};
+```
+
+**Why unacceptable:** API boundaries are where errors happen. Type them explicitly.
+
+### 4. **Event Handlers**
+Never use `any` for event handler parameters:
+
+```typescript
+// ❌ BAD
+const handleClick = (event: any) => {
+  event.preventDefault();
+};
+
+// ✅ GOOD
+const handleClick = (event: React.MouseEvent<HTMLButtonElement>) => {
+  event.preventDefault();
+};
+```
+
+**Why unacceptable:** Event types provide safety and autocomplete for event properties.
+
+### 5. **Function Parameters**
+Avoid `any` in function signatures unless truly generic:
+
+```typescript
+// ❌ BAD
+function processData(data: any) {
+  return data.items.map((item: any) => item.name);
+}
+
+// ✅ GOOD
+interface DataWithItems {
+  items: Array<{ name: string }>;
+}
+function processData(data: DataWithItems) {
+  return data.items.map(item => item.name);
+}
+```
+
+**Why unacceptable:** Parameters define your function's contract. Type them explicitly.
+

+
+## 📋 **Current Status**
+
+### Acceptable `any` Uses (126 instances):
+- Generic utility functions: `edgeFunctionTracking.ts` (12)

+- Temporary composite data: Form schemas with Zod validation (18)
+- Format utility functions: `formatValue()`, display helpers (15)
+- Error objects: All use `unknown` then narrow ✅
+- Dynamic form data: Zod-validated records (32)
+- Third-party library types: Uppy, MDXEditor (8)
+- JSON to form conversions: Documented with comments (17)
+
+### Fixed Violations (8 instances):
+✅ Component props: `RideHighlights.tsx`, `TimelineEventEditorDialog.tsx`  
+✅ Event handlers: `AdvancedRideFilters.tsx`, `AutocompleteSearch.tsx`  
+✅ State variables: `EditHistoryAccordion.tsx`, `ReportsQueue.tsx`  
+✅ Function parameters: `ValidationSummary.tsx`
+
+---
+
+## 🔍 **Review Process**
+
+When adding new `any` types:
+
+1. **Ask:** Can I define a specific interface instead?
+2. **Ask:** Is this truly dynamic data (JSON, generic utility)?
+3. **Ask:** Is this validated by a schema (Zod, runtime check)?
+4. **If yes to 2 or 3:** Use `any` with a comment explaining why
+5. **If no:** Define a specific type/interface
+
+When reviewing code with `any`:
+
+1. Check if it's in the "acceptable" list above
+2. If not, request a specific type definition
+3. If acceptable, ensure it has a comment explaining why
