+# Spark Runtime Type Errors - Resolution Complete
+
+## Problem
+The codebase had 54 TypeScript errors where `window.spark` was not recognized as a valid property. This occurred because the global type definitions for the Spark runtime weren't being properly recognized by TypeScript.
+
+## Root Cause
+The Spark runtime was implemented in `src/lib/spark-runtime.ts` and properly assigned to `window.spark` at runtime, but TypeScript didn't have the type definitions available during compilation.
+
+## Solution Implemented
+
+### 1. Created Global Type Definitions
+Created `/workspaces/spark-template/src/global.d.ts` with complete type definitions for the Spark runtime:
+
+```typescript
+declare global {
+  interface Window {
+    spark: {
+      llmPrompt: (strings: TemplateStringsArray, ...values: any[]) => string
+      llm: (prompt: string, modelName?: string, jsonMode?: boolean) => Promise<string>
+      user: () => Promise<{
+        avatarUrl: string
+        email: string
+        id: string
+        isOwner: boolean
+        login: string
+      }>
+      kv: {
+        keys: () => Promise<string[]>
+        get: <T>(key: string) => Promise<T | undefined>
+        set: <T>(key: string, value: T) => Promise<void>
+        delete: (key: string) => Promise<void>
+      }
+    }
+  }
+  var spark: Window['spark']
+}
+```
+
+### 2. Updated TypeScript Configuration
+Modified `tsconfig.json` to explicitly include the global type definitions file.
+
+### 3. Added Type References to All Files Using Spark
+Added `/// <reference path="../global.d.ts" />` directives to all files that use `window.spark`:
+
+**Components:**
+- `FeatureIdeaCloud.tsx`
+- `PlaywrightDesigner.tsx`
+- `StorybookDesigner.tsx`
+- `TemplateExplorer.tsx`
+- `UnitTestDesigner.tsx`
+
+**Hooks:**
+- `hooks/data/use-seed-data.ts`
+- `hooks/data/use-seed-templates.ts`
+- `hooks/json-ui/use-data-sources.ts`
+- `hooks/orchestration/use-actions.ts`
+- `hooks/use-component-tree-loader.ts`
+
+**Library Files:**
+- `lib/ai-service.ts`
+- `lib/error-repair-service.ts`
+- `lib/project-service.ts`
+- `lib/protected-llm-service.ts`
+- `lib/spark-runtime.ts`
+- `lib/unified-storage.ts`
+
+### 4. Removed Unnecessary @ts-expect-error Comments
+Removed all `@ts-expect-error` comments that were previously needed to suppress the missing property errors (8 from `ai-service.ts` and 2 from `error-repair-service.ts`).
+
+### 5. Updated Spark Runtime Implementation
+Enhanced `src/lib/spark-runtime.ts` to fully implement the expected interface:
+- Added `llmPrompt` template literal function
+- Updated `llm` function to match expected signature
+- Updated `user` function to return a Promise with correct shape
+- Ensured `kv` methods have proper type signatures
+
+## Verification
+All TypeScript errors have been resolved. Running `npx tsc --noEmit` now produces zero errors related to `window.spark`.
+
+## Benefits
+1. **Type Safety**: Full TypeScript support for Spark runtime API
+2. **IntelliSense**: Developers get autocomplete and type hints when using `window.spark`
+3. **Error Prevention**: Compile-time checking prevents runtime errors from incorrect API usage
+4. **Maintainability**: Clear, documented interface for the Spark runtime
+
+## Related Systems
+The Spark runtime provides:
+- **KV Storage**: IndexedDB-backed persistent storage (with optional Flask API backend)
+- **LLM Service**: Mock LLM service for AI features
+- **User Service**: Mock user authentication and profile data
+
+The implementation correctly defaults to IndexedDB storage, with Flask API as an optional backend that can be enabled via environment variables or UI settings.
