## Historical Pattern Analysis
### Summary
- Similar past changes found: X
- Related incidents: Y
- Pattern confidence: [HIGH/MEDIUM/LOW]
### Similar Past Changes
#### [Commit SHA] - [Date]
- **Author:** [name]
- **Message:** [commit message]
- **Resources Changed:** [list]
- **Outcome:** [success/issues]
### Identified Patterns
#### Pattern: [Pattern Name]
- **Description:** [what the pattern is]
- **Frequency:** [how often it occurs]
- **Relevance:** [why it matters for current change]
### Related Incidents
#### Incident: [Date/Reference]
- **What Happened:** [description]
- **Root Cause:** [cause]
- **Resolution:** [how it was fixed]
- **Lesson:** [what we learned]
- **Relevance to Current Change:** [why this matters now]
### Risk Predictions
Based on historical data:
| Risk | Likelihood | Basis |
|------|------------|-------|
| [Risk 1] | [HIGH/MED/LOW] | [historical evidence] |
| [Risk 2] | [HIGH/MED/LOW] | [historical evidence] |
### Recommendations
Based on past experience:
1. [Recommendation 1]
2. [Recommendation 2]
