Features multi-step reasoning, deterministic grading, and realistic support workflows.20 21**Real-world Task**: Agents learn to resolve customer support tickets across 3 scenarios with varying complexity, customer tiers, and issue types.22 23---24 25## ✨ Features26 27✅ **Real-World Task** - Customer support ticket resolution (not a toy)  28✅ **Full OpenEnv Spec Compliance** - Typed models, `step()`/`reset()`/`state()` API, openenv.yaml v1  29✅ **3 Tiered Tasks** - Easy/Medium/Hard with deterministic graders, 0.0-1.0 scores  30✅ **Meaningful Rewards** - Partial credit, penalties for poor actions, differentiated scores  31✅ **Reproducible Baseline** - `inference.py` with MANDATORY-compliant logging  32✅ **Production Deployment** - Docker + Hugging Face Spaces compatible  33✅ **OpenEnv HTTP API** - `/reset`, `/step`, `/state`, `/health` endpoints  34 35---36 37## 🎯 Environment Overview38 39### Tasks (Easy → Medium → Hard)40 41| Task | Scenario | Tier | Difficulty | Grade Components |42|------|----------|------|-----------|------------------|43| **Task 1** | Billing: "Charged twice for subscription" | Free | Easy | Action (50%) + Reasoning (20%) + Tier-awareness (20%) |44| **Task 2** | Technical: "403 error when accessing dashboard" | Pro | Medium | Step Quality (40%) + Efficiency (30%) + Escalation (20%) |45| **Task 3** | Enterprise: Multi-category (billing + technical + account) | Enterprise | Hard | Priority Judgment (25%) + Ambiguity (20%) + Risk Management (20%) + Reasoning (15%) + Retention (20%) |46 47### Action Space (Constrained)48 49```python50action_type: Literal[51    "request_more_info",      # Ask for clarification ($0 cost)52    "escalate_to_human",      # Route to human agent ($15 cost)53    "suggest_knowledge_base", # Search KB ($1 cost)54    "assign_department",      # Route to specific team ($5 cost)55    "close_resolved",         # Mark as resolved56    "request_callback"        # Schedule callback ($10 cost)57]58```59 60### Observation Space61 62```python63{64    "ticket_id": "TKT-000001-f-BIL",65    "customer_message": "Why was I charged twice?",66    "customer_tier": "free|pro|enterprise",67    "priority": "low|medium|high",68    "category": "billing|technical|feature_request|account",69    "conversation_history": ["..."],70    "kb_match_score": 0.85,71    "sentiment_score": -0.3,72    "customer_tenure_days": 45,73    "total_revenue": 1200.5074}75```76 77### Reward System78 79- **Deterministic**: Same seed → same ticket → same reward80- **Partial Credit**: Multiple scoring components, not binary 0/181- **Penalties**: 82  -
