## 💡 Real-World Examples
### Example 1: LLM Failure
**BEFORE:**
```
[Error] API timeout - summary generation failed
No retry, user gets empty report
```
**AFTER:**
```
[LMStudio] Attempt 1/3 failed: timeout
[LMStudio] Retrying in 1.2s...
[LMStudio] Attempt 2/3 failed: timeout
[LMStudio] Retrying in 2.5s...
[LMStudio] All retries exhausted
[Narrative] LMStudio failed, trying HuggingFace API...
[HF API] ✓ Success
Report generated successfully
```
---
### Example 2: Vague Summary
**BEFORE:**
```
Most participants mentioned symptoms.
Many experienced side effects.
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. Invalid rows: ['Transcript 1']
ValueError: Quality scores must be between 0 and 1. Invalid rows: ['Transcript 2']
ValueError: Duplicate transcript IDs found: ['Transcript 1']
CSV export failed - data integrity issues detected
```
✅ Errors caught before report generation
