# Implementation Guide: Protocol 13 - Real-Time Tracking

**Date:** 2025-11-21
**Status:** 🚧 IN PROGRESS
**Priority:** P0 - CRITICAL

## What's Done ✅

1. **Created [`realtime_tracking.py`](../optimization_engine/realtime_tracking.py)**
   - `RealtimeTrackingCallback` class
   - Writes JSON files after EVERY trial (atomic writes)
   - Files: optimizer_state.json, strategy_history.json, trial_log.json, landscape_snapshot.json, confidence_history.json

2. **Fixed Multi-Objective Strategy (Protocol 12)**
   - Modified [`strategy_selector.py`](../optimization_engine/strategy_selector.py)
   - Added `_recommend_multiobjective_strategy()` method
   - Multi-objective: Random (8 trials) → TPE with multivariate

## What's Needed ⚠️

### Step 1: Integrate Callback into IntelligentOptimizer

**File:** [`optimization_engine/intelligent_optimizer.py`](../optimization_engine/intelligent_optimizer.py)

**Line 48 - Add import:**
```python
from optimization_engine.adaptive_characterization import CharacterizationStoppingCriterion
from optimization_engine.realtime_tracking import create_realtime_callback  # ADD THIS
```

**Line ~90 in `__init__()` - Create callback:**
```python
def __init__(self, study_name: str, study_dir: Path, config: Dict, verbose: bool = True):
    # ... existing init code ...

    # Create realtime tracking callback (Protocol 13)
    self.realtime_callback = create_realtime_callback(
        tracking_dir=self.tracking_dir,
        optimizer_ref=self,
        verbose=self.verbose
    )
```

**Find ALL `study.optimize()` calls and add callback:**

Search for: `self.study.optimize(`

Replace pattern:
```python
# BEFORE:
self.study.optimize(objective_function, n_trials=check_interval)

# AFTER:
self.study.optimize(
    objective_function,
    n_trials=check_interval,
    callbacks=[self.realtime_callback]
)
```

**Locations to fix (approximate line numbers):**
- Line ~190: Characterization phase
- Line ~230: Optimization phase (multiple locations)
- Line ~260: Refinement phase
- Line ~380: Fallback optimization

**CRITICAL:** EVERY `study.optimize()` call must include `callbacks=[self.realtime_callback]`

### Step 2: Test Realtime Tracking

```bash
# Clear old results
cd studies/bracket_stiffness_optimization_V2
del /Q 2_results\study.db
rd /S /Q 2_results\intelligent_optimizer

# Run with new code
python -B run_optimization.py --trials 10

# Verify files appear IMMEDIATELY after each trial
dir 2_results\intelligent_optimizer
# Should see:
# - optimizer_state.json
# - strategy_history.json
# - trial_log.json
# - landscape_snapshot.json
# - confidence_history.json

# Check file updates in real-time
python -c "import json; print(json.load(open('2_results/intelligent_optimizer/trial_log.json'))[-1])"
```

## Dashboard Implementation Plan

### Backend API Endpoints (Python/FastAPI)

**File:** [`atomizer-dashboard/backend/api/routes/optimization.py`](../atomizer-dashboard/backend/api/routes/optimization.py)

**Add new endpoints:**

```python
@router.get("/studies/{study_id}/metadata")
async def get_study_metadata(study_id: str):
    """Read optimization_config.json for objectives, design vars, units."""
    study_dir = find_study_dir(study_id)
    config_file = study_dir / "optimization_config.json"

    with open(config_file) as f:
        config = json.load(f)

    return {
        "objectives": config["objectives"],
        "design_variables": config["design_variables"],
        "constraints": config.get("constraints", []),
        "study_name": config["study_name"]
    }

@router.get("/studies/{study_id}/optimizer-state")
async def get_optimizer_state(study_id: str):
    """Read realtime optimizer state from intelligent_optimizer/."""
    study_dir = find_study_dir(study_id)
    state_file = study_dir / "2_results/intelligent_optimizer/optimizer_state.json"

    if not state_file.exists():
        return {"available": False}

    with open(state_file) as f:
        state = json.load(f)

    return {"available": True, **state}

@router.get("/studies/{study_id}/pareto-front")
async def get_pareto_front(study_id: str):
    """Get Pareto-optimal solutions for multi-objective studies."""
    study_dir = find_study_dir(study_id)
    db_path = study_dir / "2_results/study.db"

    storage = optuna.storages.RDBStorage(f"sqlite:///{db_path}")
    study = optuna.load_study(study_name=study_id, storage=storage)

    if len(study.directions) == 1:
        return {"is_multi_objective": False}

    pareto_trials = study.best_trials

    return {
        "is_multi_objective": True,
        "pareto_front": [
            {
                "trial_number": t.number,
                "values": t.values,
                "params": t.params,
                "user_attrs": dict(t.user_attrs)
            }
            for t in pareto_trials
        ]
    }
```

      const data = await res.json();
      setState(data);
    };

    fetchState();
    const interval = setInterval(fetchState, 1000); // Update every second
    return () => clearInterval(interval);
  }, [studyId]);

      </div>
    </Card>
  );
}
```

**2. Pareto Front Plot**

**File:** `atomizer-dashboard/frontend/src/components/ParetoPlot.tsx` (CREATE NEW)

```typescript
import { ScatterChart, Scatter, XAxis, YAxis, CartesianGrid, Tooltip, Cell, ResponsiveContainer } from 'recharts';

interface ParetoData {
  trial_number: number;
  values: [number, number];
  params: Record<string, number>;
  constraint_satisfied?: boolean;
}

export function ParetoPlot({ paretoData, objectives }: {
  paretoData: ParetoData[];
  objectives: Array<{ name: string; unit?: string }>;
}) {
  if (paretoData.length === 0) {
    return (
      <div className="h-64 flex items-center justify-center text-dark-300">
        No Pareto front data yet
      </div>
    );
  }

  const data = paretoData.map(trial => ({
    x: trial.values[0],
    y: trial.values[1],
    trial_number: trial.number,
    feasible: trial.constraint_satisfied !== false
  }));

  return (
    <ResponsiveContainer width="100%" height={400}>
      <ScatterChart>
        <CartesianGrid strokeDasharray="3 3" stroke="#334155" />
        <XAxis
          type="number"
          dataKey="x"
          name={objectives[0]?.name || 'Objective 1'}
          stroke="#94a3b8"
          label={{
            value: `${objectives[0]?.name || 'Objective 1'} ${objectives[0]?.unit || ''}`.trim(),
            position: 'insideBottom',
            offset: -5,
            fill: '#94a3b8'
          }}
        />
        <YAxis
          type="number"
          dataKey="y"
          name={objectives[1]?.name || 'Objective 2'}
          stroke="#94a3b8"
          label={{

            angle: -90,
            position: 'insideLeft',
            fill: '#94a3b8'
          }}
        />
        <Tooltip
          contentStyle={{ backgroundColor: '#1e293b', border: 'none', borderRadius: '8px' }}
          labelStyle={{ color: '#e2e8f0' }}
        />
        <Scatter name="Pareto Front" data={data}>
          {data.map((entry, index) => (
            <Cell
              key={`cell-${index}`}
              fill={entry.feasible ? '#10b981' : '#ef4444'}
              r={entry.feasible ? 6 : 4}

          ))}
        </Scatter>
      </ScatterChart>
    </ResponsiveContainer>
  );
}
```

**3. Update Dashboard.tsx**

**File:** [`atomizer-dashboard/frontend/src/pages/Dashboard.tsx`](../atomizer-dashboard/frontend/src/pages/Dashboard.tsx)

Add imports at top:
```typescript
import { OptimizerPanel } from '../components/OptimizerPanel';
import { ParetoPlot } from '../components/ParetoPlot';
```

Add new state:
```typescript
const [studyMetadata, setStudyMetadata] = useState(null);
const [paretoFront, setParetoFront] = useState([]);
```

Fetch metadata when study selected:
```typescript
useEffect(() => {
  if (selectedStudyId) {
    fetch(`/api/optimization/studies/${selectedStudyId}/metadata`)
      .then(res => res.json())
      .then(setStudyMetadata);

    fetch(`/api/optimization/studies/${selectedStudyId}/pareto-front`)
      .then(res => res.json())
      .then(data => {
        if (data.is_multi_objective) {
          setParetoFront(data.pareto_front);
        }
      });
  }
}, [selectedStudyId]);
```

Add components to layout:
```typescript
{/* Add after metrics grid */}
<div className="grid grid-cols-2 gap-6 mb-6">
  <OptimizerPanel studyId={selectedStudyId} />
  {paretoFront.length > 0 && (
    <Card title="Pareto Front">
      <ParetoPlot
        paretoData={paretoFront}
        objectives={studyMetadata?.objectives || []}
      />
    </Card>
  )}
</div>
```

## Testing Checklist

- [ ] Realtime callback writes files after EVERY trial
- [ ] optimizer_state.json updates in real-time
- [ ] Dashboard shows optimizer panel with live updates
- [ ] Pareto front appears for multi-objective studies
- [ ] Units are dynamic (read from config)
- [ ] Multi-objective strategy switches from random → TPE after 8 trials

---

## Next Steps

1. Integrate callback into IntelligentOptimizer (Steps above)
2. Implement backend API endpoints
3. Create frontend components
4. Test end-to-end with bracket study
5. Document as Protocol 13
