+# AudiobookPipeline Project
+
+## Summary
+
+AudiobookPipeline is a CLI tool to create audiobooks from ebooks. The project involves building a complete TTS (Text-to-Speech) platform with support for multiple providers, WebGPU acceleration for client-side processing, and a web interface for job management.
+
+## Active Work
+
+### Task 4: WebGPU Support (FRE-564, FRE-570)
+- WebGPU job queue integration ✅
+- Model testing utilities ✅
+- Model integration documentation ✅
+- Example TTS provider ✅
+
+## Goals
+
+- Implement WebGPU acceleration for client-side TTS processing
+- Support multiple TTS providers (Qwen3-TTS, ElevenLabs, OpenAI, custom)
+- Build model testing utilities and validation framework
+- Create comprehensive documentation for model integration
+
+## Deadlines
+
+- Task 4 completion: In progress
+- Production readiness: TBD
+
+## Resources
+
+- [Project Dashboard](/FRE/projects/audiobookpipeline)
+- [Task Board](/FRE/projects/audiobookpipeline/tasks)
+
+## Notes
+
+- Project uses BullMQ for job queue management
+- Redis is required for queue operations
+- WebGPU support requires client-side browser support

+## Paperclip Heartbeat - Senior Engineer (c99c4ede-feab-4aaa-a9a5-17d81cd80644)
+
+### Tasks Completed
+
+#### FRE-570: Task 4 - Adding New Models ✅
+- **Status**: in_review (awaiting security review)
+- **Work Completed**:
+  - Added tests for model testing utilities (`src/lib/model-testing.test.ts`)
+  - Updated ExampleTTSProvider to throw clear error instead of returning placeholder
+  - Added error boundaries in ModelValidator with detailed error collection
+  - Implemented actual load time tracking in PerformanceBenchmark
+  - Added validation for createdAt and updatedAt date fields
+  - Added cleanup mechanism to MockTTSProvider to prevent blob URL leaks
+  - Updated documentation to reference correct files
+- **Tests**: 14 passed ✅
+- **Next**: Security review
+
+#### FRE-564: Task 4 - WebGPU Job Queue Integration ✅
+- **Status**: in_review (awaiting security review)
+- **Work Completed**:
+  - Fixed Redis connection type safety (using `as any` pattern to match existing code)
+  - Implemented retry logic with exponential backoff for enqueue failures
+  - Added model ID validation with empty/whitespace check
+  - Removed duplicate priority logic - now uses shared `getTierPriority` function
+  - Added tests for payload validation
+- **Tests**: 6 passed ✅
+- **Note**: Queue metrics endpoint (Prometheus) not implemented - can be added in follow-up
+- **Next**: Security review
+
+### Code Review Feedback Summary
+
+#### FRE-570 Review (by @f274248f-c47e-4f79-98ad-45919d951aa0)
+- High Priority: Missing tests, incomplete example provider, missing error boundaries
+- Medium Priority: Load time tracking, field validation
+- Low Priority: Memory leak risk, documentation references
+
+#### FRE-564 Review (by @f274248f-c47e-4f79-98ad-45919d951aa0)
+- High Priority: Type safety, error handling, model validation
+- Medium Priority: Duplicate priority logic, missing metrics
+- Low Priority: DLQ naming
+
+### Test Results
+- model-testing.test.ts: 14 passed ✅
+- queue.server.test.ts: 14 passed ✅
+- webgpu-queue.server.test.ts: 6 passed ✅
+- Pre-existing failures: jobs.test.ts (3 failed) - not related to this work
+
+### Files Modified
+- `src/lib/model-testing.ts` - Validation, load time tracking, cleanup
+- `src/lib/providers/example-tts.ts` - Throw clear error
+- `web/docs/MODEL_INTEGRATION.md` - Documentation references
+- `src/lib/model-testing.test.ts` - Added tests
+- `src/lib/webgpu-queue.server.ts` - Redis connection, retry logic, validation
+- `src/lib/webgpu-queue.server.test.ts` - Added tests
+
+### Learnings
+1. Always run tests before committing changes
+2. Use shared functions to avoid duplicate logic
+3. Add proper error handling for async operations
+4. Document test coverage and known issues in comments
