Sloth — AI Workforce Intelligence Demo
Hugging Face Spaces · v2.0 with Harness Engineering
═══════════════════════════════════════════════════
Harness layers implemented:
1. Verification Loop — every data point cross-checked before delivery
2. Confidence Scoring — each result carries a reliability score
3. Audit Trail — timestamped source citation on every alert
4. Phase Gates — structured extraction phases with validation
5. Range Validation — tax/wage figures checked against known bounds
6. Fallback Recovery — graceful degradation if any layer fails
7. Session Tracing — every query gets a unique trace ID
