1229 +**How Metrics Inform AKEL Improvements:**
1230 +
1231 +1. **Identify Weak Areas:**
1232 +
1233 +* Low TIGERScore → Review prompt engineering
1234 +* High hallucination → Strengthen evidence grounding

1238 +
1239 +* Test prompt variations
1240 +* Measure impact on quality metrics
1241 +* Deploy winners automatically
1242 +
1243 +3. **Alert Thresholds:**
1244 +
1245 +* TIGERScore drops below 75 → Alert team
1246 +* Hallucination rate exceeds 7% → Pause auto-publishing
1247 +* IRR below 0.6 → Moderator training needed
1248 +
1249 +4. **Monthly Quality Reviews:**
