+
+### ✅ Grader Discoverability
+Multiple discovery mechanisms implemented for validator tools:

+   ```
+   - [x] Central `TASK_GRADERS` registry available

+   - [x] `validate_graders()` returns validation status
+
+3. **JSON Manifest** (`graders.json`)
+   - [x] Lists all 5 graders with metadata
+   - [x] Includes performance examples for each
+   - [x] Shows different scores (0.0 → 1.0 range)
+
+4. **API Endpoints** 
+   - [x] `GET /graders` → Returns all graders with metadata
+   - [x] `GET /graders/{task_name}` → Specific grader info
+   - [x] `GET /graders/info` → Validation status
+
+5. **Environment Properties**

+   - [x] `env.grader_metadata` property → All metadata
+   - [x] `env.grade_task(task_name, observation)` method
+
+### ✅ Score Variation (Different Scores for Different Performances)
+**Validation Results:**
+
+```
+Task 1: Basic RAM Reduction
+├─ Worst Performance    (RAM=100%, Energy=10kWh, Steps=50)    → Score: 0.000 ✅
+├─ Poor Performance     (RAM=90%, Energy=9kWh, Steps=20)      → Score: 0.293 ✅
+├─ Medium Performance   (RAM=75%, Energy=8kWh, Steps=8)       → Score: 0.853 ✅
+└─ Good Performance     (RAM=70%, Energy=7.5kWh, Steps=5)    → Score: 1.000 ✅
+
+Task 2: Energy Optimization
+├─ Below Target (RAM=65%, Energy=5kWh)    → Score: 1.000 ✅
+├─ At Target    (RAM=75%, Energy=6kWh)   → Score: 1.000 ✅
+└─ Above Target (RAM=85%, Energy=7kWh)   → Score: 0.525 ✅
+
+Task 3: Balanced Optimization
+├─ Below Target (RAM=50%, Energy=4kWh)    → Score: 0.925 ✅
+├─ At Target    (RAM=60%, Energy=5kWh)   → Score: 0.900 ✅
+└─ Above Target (RAM=70%, Energy=6kWh)   → Score: 0.497 ✅
+
+Tasks 4-5: Similar score variation patterns demonstrated ✅
+```
