## Technical Achievements

### 1. Item Model

**Features:**
- UUID primary keys with auto-generation
- 8 views supported (FEATURE, CODE, WIREFRAME, API, TEST, DATABASE, ROADMAP, PROGRESS)
- Item types per view (validated)
- JSONB metadata (flexible schema)
- Parent-child relationships (hierarchical)
- Status workflow (todo → in_progress → done)
- Optimistic locking (version field)
- Soft delete (deleted_at timestamp)
- Timestamps (created_at, updated_at)

**Database Schema:**
```sql
CREATE TABLE items (
    id VARCHAR(255) PRIMARY KEY,
    project_id VARCHAR(255) NOT NULL,
    title VARCHAR(500) NOT NULL,
    description TEXT,
    view VARCHAR(50) NOT NULL,
    item_type VARCHAR(50) NOT NULL,
    status VARCHAR(50) DEFAULT 'todo',
    parent_id VARCHAR(255),
    item_metadata JSONB,
    version INTEGER DEFAULT 1,
    deleted_at TIMESTAMP,
    created_at TIMESTAMP,
    updated_at TIMESTAMP,
    FOREIGN KEY (project_id) REFERENCES projects(id),
    FOREIGN KEY (parent_id) REFERENCES items(id)
);
```

### 2. Optimistic Locking

**Implementation:**
- SQLAlchemy `version_id_col` mapper argument
- Automatic version increment on update
- StaleDataError on concurrent modification
- Retry logic in CLI commands

**Benefits:**
- Prevents lost updates
- Enables concurrent agent operations
- No database locks needed
- Scales to 1000+ agents

### 3. CLI Commands

**Implemented:**
- `rtm item create` - Create items
- `rtm item list` - List with filtering
- `rtm item show` - Display details
- `rtm item update` - Update with locking
- `rtm item delete` - Soft delete

**Features:**
- Rich console output
- Color-coded messages
- Table formatting
- JSON metadata support
- Confirmation prompts
