|
|
|
**Coverage**: 92.3% (1232/1336)
|
|
|
|
### Pattern Validation
|
|
|
|
- Tested recovery patterns on real errors
|
|
- Measured MTTR (Mean Time To Recovery)
|
|
- Documented diagnostic workflows
|
|
|
|
### Results
|
|
|
|
**V_instance = 0.85** ✓
|
|
**V_meta = 0.78** (approaching target)

## Iteration 3: Final Convergence (60 min)
|
|
|
|
### Completed Taxonomy
|
|
|
|

|
|
|
|
**Final Coverage**: 95.4% (1275/1336) ✅
|
|
|
|
### Diagnostic Workflows
|
|
|
|
Created 8 step-by-step diagnostic workflows for top categories
|

|
|
|
Documented prevention strategies for all categories
|
|
|
|
### Results
|
|
|
|
**V_instance = 0.92** ✓ ✓ (2 consecutive ≥ 0.80)
|
|
**V_meta = 0.84** ✓ ✓ (2 consecutive ≥ 0.80)
|
|
|
|
**CONVERGED** in 3 iterations! ✅

## Replication Tips
|
|
|
|
### To Achieve Rapid Convergence
|
|
|
|
**1. Invest in Iteration 0**
|
|
```
|
|
Standard: 60 min → 5-6 iterations
|
|
Strong: 120 min → 3-4 iterations
|
|
|
|
ROI: 1 hour extra → save 2-3 hours total
|
|
```
|
|
|
|
**2. Start Automation Early**
|
|
```
|
|
Don't wait for patterns to stabilize
|
|
If ROI > 3x, automate in Iteration 1
|
|
```
|
|
|
|
**3. Set Clear Thresholds**
|
|
```
|
|
Error classification: ≥ 95%
|
|
Pattern coverage: Top 80% of errors
|
|
Automation: ≥ 20% prevention
|
|
```
|
|
|
|
**4. Borrow from Prior Work**
|
|
```
|
|
Error categories are universal
|
|
Recovery patterns largely transferable
|
|
Start with proven taxonomy
|
|
```
