## ⚠️ ISSUES & RECOMMENDATIONS

### 1. Dead Code trong `src/shm.rs`
- `ShmAllocator` struct được khai báo nhưng không sử dụng
- Đã có `#[allow(dead_code)]` → OK cho production

### 2. `theus/workflow.py` quá mỏng
- Chỉ 296 bytes, có thể merge vào `engine.py`

### 3. `theus/audit.py` minimal
- Chỉ 433 bytes, có thể cần mở rộng

### 4. Examples cần cleanup
- `async_outbox/` có code thừa và import lỗi (đã sửa)

### 5. Thiếu explicit tests cho Conflict Resolution
- `ConflictManager.report_conflict()` chưa có unit test riêng

### 6. Zombie Collector Limitation (Windows)
- Feature cleanups dead processes' shared memory based on PID.
- **Vấn đề:** Trên Windows, định danh Shared Memory giữa Python (`shm.SharedMemory`) và Rust (`shared_memory` crate) có sự không tương thích về namespace (Local/Global prefix), khiến Rust Core không thể mở và unlink segment do Python tạo ra. Test đã bị disable (`.disabled`) để tránh fail CI.
- **Plan:** Fix trong v3.1 hoặc sau khi verify trên Linux.
