Several had positive outcomes. ``` ✅ Accepted, no validation **AFTER:** ``` [Warning] Summary quality issues (score: 0.45): - Contains vague terms - should use specific numbers - No quantified findings [Summary] Retrying with stricter validation... FINAL: "8 out of 12 participants (67%) mentioned fatigue. 5 participants (42%) experienced headaches. 9 participants (75%) reported improved mobility." ``` ✅ Quality score: 0.85 - Passed --- ### Example 3: Consensus Claim **BEFORE:** ``` "STRONG CONSENSUS: 5 out of 10 participants agree" ``` ❌ 50% labeled as "strong consensus" (needs 80%) ❌ Not detected, published in report **AFTER:** ``` [CONSENSUS VERIFICATION NOTES]: - Claimed 'STRONG CONSENSUS' but 5/10 is only 50% (needs ≥80%) Summary updated with warning ``` ✅ Error detected and flagged --- ### Example 4: CSV Validation **BEFORE:** ```csv Transcript ID,Quality Score,Word Count Transcript 1,1.5,500 Transcript 2,-0.2,100 Transcript 1,0.8,600 ``` ❌ Quality score > 1.0 (invalid) ❌ Negative quality score ❌ Duplicate ID ❌ All accepted, corrupt data in reports **AFTER:** ``` ValueError: Quality scores must be between 0 and 1.
