Maintains terminal buffer for reconnections. - **Session** (`src/session.ts`): Wraps Claude CLI as PTY subprocess.

### PTY Spawn Modes
**One-shot mode** (prompt execution):
```typescript
pty.spawn('claude', ['-p', '--dangerously-skip-permissions', prompt], { ... })
```
**Interactive mode** (persistent terminal):
```typescript
pty.spawn('claude', ['--dangerously-skip-permissions'], { ... })

### Idle Detection ### Idle Detection
Session detects idle by watching for prompt character (`❯` or `\u276f`) and waiting 2 seconds without activity. RespawnController uses the same patterns plus spinner characters to detect working state.

RespawnController uses the same patterns plus spinner characters to detect working state.
### Long-Running Session Support
Sessions are optimized for 12-24+ hour runs with automatic buffer management:
**Buffer Limits:**
- Terminal buffer: 5MB max, trims to 4MB when exceeded
- Text output: 2MB max, trims to 1.5MB when exceeded
- Messages: 1000 max, keeps most recent 800 when exceeded
**Performance Optimizations:**
- Server-side terminal batching at 60fps (16ms intervals)
- Client-side requestAnimationFrame batching for smooth rendering
- Buffer statistics available via session details for monitoring
**Buffer Stats Response:**
```typescript
{
bufferStats: {
terminalBufferSize: number; // Current terminal buffer size in bytes
textOutputSize: number; // Current text output size in bytes
messageCount: number; // Number of parsed messages
maxTerminalBuffer: number; // Max allowed terminal buffer
maxTextOutput: number; // Max allowed text output
maxMessages: number; // Max allowed messages
}
}

#### Quick Start Button
The Quick Start feature reduces the typical 5-step workflow to just 1-2 steps:
**Before (5 steps):**
1. Go to Cases tab
2. Create a case
3. Click the case
4. Switch to Run tab
5. Click Interactive
**After (1-2 steps):**
1. (Optional) Select a case from dropdown
2. Click "Quick Start"
The Quick Start button will:
- Create a case folder in `~/claudeman-cases/` if it doesn't exist
- Generate a CLAUDE.md file for the case
- Create a new session pointed to that case directory
- Start an interactive Claude terminal
- Focus the terminal so you can start working immediately

## Long-Running Sessions
Claudeman is optimized for extended autonomous sessions (12-24+ hours):
### Buffer Management
To prevent memory issues during long runs, buffers are automatically managed:
- **Terminal buffer**: Max 5MB, trims to 4MB when exceeded
- **Text output**: Max 2MB, trims to 1.5MB when exceeded
- **Messages**: Max 1000, keeps most recent 800 when exceeded
### Performance Optimizations
- **Server-side batching**: Terminal data batched at 60fps (16ms intervals)
- **Client-side batching**: requestAnimationFrame for smooth rendering
- **Aggressive process cleanup**: SIGKILL with process group termination
### Resource Monitoring
Each session displays real-time resource usage:
- Memory usage (terminal + text buffers)
- Message count
- Color-coded warnings (green/yellow/red based on usage)
### Kill Sessions
- Click `✕` on individual session cards to terminate
- Click `Kill All` button in sessions panel to terminate all at once
- Sessions are forcefully killed with SIGKILL after SIGTERM timeout
