================================================================================
THREE GRADED TASKS
================================================================================

TASK 1: SPAM DETECTION (Easy)
Description: Binary classification of emails as spam or legitimate
Dataset: 10 synthetic emails
Grader: Accuracy-based (correct_classifications / total)
Expected Score: 0.80-0.85
Reward Signals: Per-email classification accuracy

TASK 2: MULTI-CLASS ROUTING (Medium)
Description: 4-class classification + team routing + priority setting
Dataset: 12 diverse emails (spam/normal/urgent/billing)
Grader: 50% classification accuracy + 50% routing accuracy
Expected Score: 0.70-0.75
Reward Signals: Classification + routing + priority accuracy

TASK 3: CONTEXT-AWARE TRIAGE (Hard)
Description: Complex triage with VIP handling, SLA awareness, escalation
Dataset: 20 emails with rich context metadata
Grader: 50% classification + 30% priority + 20% routing
Expected Score: 0.60-0.70
Reward Signals: Weighted combination of all three signals

================================================================================
REWARD FUNCTION DESIGN
================================================================================

Per-Step Reward Breakdown:

- Classification accuracy: 40% weight
- Routing accuracy: 30% weight
- Priority accuracy: 30% weight

Value Range: [0.0, 1.0]
Partial Progress: Yes (signal throughout entire episode)
Negative Penalties: Yes (incorrect actions penalized)

Formula:
reward = (0.4 _ class_correct) + (0.3 _ routing_correct) +
(0.3 \* priority_scaled_accuracy)
reward = clamp(reward, 0.0, 1.0)

================================================================================
LOCAL TESTING RESULTS
================================================================================

Test 1: All Tasks Load Successfully

- spam_detection: 10 emails, SpamDetectionGrader
- multi_class_routing: 12 emails, MultiClassRoutingGrader

Test 2: Step/Reward API

- Observation returned correctly
- Reward in [0.0, 1.0] range
- Info dict contains expected keys
- Done flag works correctly

Test 3: JSON Serialization

- Observation serializes to JSON
- Reward serializes to JSON
- All models support model_dump(mode="json")

Test 4: State API

- State structure complete
- History tracking works
- Step counting accurate

Test 5: Full Episode

- Episode completes successfully
- Total reward accumulated correctly
- Final score computed properly

Test 6: Task Graders

- All 3 task graders initialized correctly
- Grader types match task assignments
- Score computation works

HOW TO USE
================================================================================

1. Local Development:

   ```
   cd d:/Projects/meta-hackathon
   pip install -r requirements.txt
   python -c "from environment import EmailTriageEnv;
              env = EmailTriageEnv('spam_detection');
              obs = env.reset();
              print('OK')"
   ```

2. Run Flask API:

   ```
   export FLASK_APP=app.py
   python app.py
   # API available at http://localhost:7860
   ```

3. Run Baseline Inference:

   ```
   export OPENAI_API_KEY="sk-..."
   export MODEL_NAME="gpt-4o-mini"
   python inference.py
   ```

4. Deploy to Hugging Face:
   - Create Space at https://huggingface.co/spaces
   - Select Docker runtime
   - Push project files

2. SYNTHETIC DATA QUALITY
   - Realistic email patterns with metadata
   - Gradual difficulty progression
   - Seeded for reproducibility
   - Includes VIP flags, SLA times, sender domains

3. MEANINGFUL REWARD SIGNALS
   - Per-step rewards, not just end-of-episode
   - Partial credit for partial correctness
   - Negative penalties for mistakes
   - Clear breakdown of contributions

4. PRODUCTION-READY DEPLOYMENT
   - Docker containerization for HF Spaces
