💡 Lessons Learned

What Went Exceptionally Well

1. Systematic Approach: Completing Sprint 3 remnants first created momentum
2. Reusable Patterns: Terraform modules and GitHub workflows are highly reusable
3. Comprehensive Documentation: MkDocs setup will save significant time
4. Security Integration: SARIF uploads provide centralized security view

Challenges Overcome

1. Matrix Complexity: Managing cross-version testing required careful workflow design
2. Performance Test Tuning: Finding realistic thresholds took iteration
3. Documentation Structure: Balancing completeness with maintainability

Improvements for Future Sprints

1. Incremental Delivery: More frequent commits would allow better tracking
2. Early Integration: Could have integrated security scanning earlier
3. Performance Baselines: Should establish baselines before adding regression checks
