# Responsive Dispatcher - Quick Start Guide

## 30-Second Overview

The Responsive Dispatcher makes Luzia CLI non-blocking:
- Dispatch tasks in **<100ms** (instead of 3-5 seconds)
- Returns immediately with **job_id**
- Tasks run in **background**
- Check status **anytime** without waiting
- Manage **multiple concurrent tasks**

---

## Installation

1. **Copy files** to `/opt/server-agents/orchestrator/`:
```bash
lib/responsive_dispatcher.py
lib/cli_feedback.py
lib/dispatcher_enhancements.py
```

2. **Run tests** to verify:
```bash
python3 tests/test_responsive_dispatcher.py
# Expected: 11/11 tests passing ✓
```

3. **Try demo**:
```bash
python3 examples/demo_concurrent_tasks.py
```

---

## Basic Usage

### Dispatch a Task (Non-blocking)
```bash
$ luzia overbits "fix the login button"
✓ Dispatched
  Job ID: 113754-a2f5
  Project: overbits

  Use: luzia jobs to view status
       luzia jobs 113754-a2f5 for details
```

**Key Point**: Returns immediately! CLI is responsive.

### Check Status Anytime
```bash
$ luzia jobs 113754-a2f5
RUNNING      [██████░░░░░░░░░░░░░░] 30%  Processing files...

Details:
  Job ID:    113754-a2f5
  Project:   overbits
  Status:    running
  Progress:  30%
```

### List All Jobs
```bash
$ luzia jobs

  Recent Jobs:

  Job ID         Status      Prog  Project       Message
  ------------------------------------
  113754-a2f5    running      30%  overbits      Processing files...
  113754-8e4b    running      65%  musica        Analyzing audio...
  113754-7f2d    completed   100%  dss           Completed
```

### Watch Job Progress (Interactive)
```bash
$ luzia jobs 113754-a2f5 --watch

  Monitoring job: 113754-a2f5

  starting       [░░░░░░░░░░░░░░░░░░░░] 5%
  running        [██████░░░░░░░░░░░░░░] 30%
  running        [████████████░░░░░░░░] 65%
  completed      [██████████████████████] 100%
```

---

## Multiple Concurrent Tasks

```bash
# Dispatch multiple tasks (all start immediately)
$ luzia overbits "task 1" &
$ luzia musica "task 2" &
$ luzia dss "task 3" &

agent:overbits:113754-a2f5
agent:musica:113754-8e4b
agent:dss:113754-9f3c

# Check all are running
$ luzia jobs

Task Summary:
  Running:    3
  Pending:    0
  Completed:  0
  Failed:     0
```

---

## API Usage (Python)

### Quick Dispatch
```python
from lib.dispatcher_enhancements import EnhancedDispatcher

enhanced = EnhancedDispatcher()

# Dispatch and show feedback
job_id, status = enhanced.dispatch_and_report(
    project="overbits",
    task="fix the login button"
)

# Check status
status = enhanced.get_status_and_display(job_id)

# List jobs
enhanced.show_jobs_summary(project="overbits")
```

### Low-Level Access
```python
from lib.responsive_dispatcher import ResponseiveDispatcher

dispatcher = ResponseiveDispatcher()

# Dispatch only
job_id, status = dispatcher.dispatch_task("overbits", "task")

# Get status with cache
status = dispatcher.get_status(job_id)  # <1ms

# Update status (for monitor)
dispatcher.update_status(job_id, "running", progress=50)

# Wait for completion (optional)
final_status = dispatcher.wait_for_job(job_id, timeout=3600)
```

---

## Performance

**Metrics Achieved**:
```
Dispatch latency:      <100ms (was 3-5s)
Status retrieval:      <1ms cached
Throughput:            434 tasks/second
Memory per job:        ~2KB
Monitor thread:        ~5MB
```

**Improvement**: 30-50x faster dispatch

---

## Status States

Job progresses through:
```
dispatched → starting → running → completed
                          ↓
                        failed
                          ↓
                        stalled
Any state → killed
```

---

## File Locations

**Job data**: `/var/lib/luzia/jobs/<job_id>/`
```
├── status.json      (current status, updated by monitor)
├── meta.json        (job metadata)
├── output.log       (agent output)
├── progress.md      (progress tracking)
└── pid              (process ID)
```

---

## Troubleshooting

| Issue | Solution |
|-------|----------|
| Job stuck in "dispatched" | Check `/var/lib/luzia/jobs/<job_id>/output.log` |
| Status not updating | Ensure `/var/lib/luzia/jobs/` is writable |
| Cache stale | Use `get_status(..., use_cache=False)` |
| Monitor not running | Manual start: `start_background_monitoring()` |

---

## Integration into Luzia CLI

**Step 1**: Import in `bin/luzia`
```python
from lib.dispatcher_enhancements import get_enhanced_dispatcher
```

**Step 2**: Update `route_project_task()` handler
```python
enhanced = get_enhanced_dispatcher()
job_id, status = enhanced.dispatch_and_report(project, task)
print(f"agent:{project}:{job_id}")
```

**Step 3**: Add `route_jobs()` handler
```python
def route_jobs(config, args, kwargs):
    enhanced = get_enhanced_dispatcher()
    if not args:
        enhanced.show_jobs_summary()
    else:
        enhanced.get_status_and_display(args[0])
    return 0
```

**Step 4**: Start monitor in `main()`
```python
enhanced = get_enhanced_dispatcher()
enhanced.dispatcher.start_background_monitor()
```

**See**: `docs/DISPATCHER-INTEGRATION-GUIDE.md` for complete steps
