Major bugs fixed - Unenrolled default intentions not realizable (commit: 1ed53c2542e14c1606243b997aa3dcd12df77aa9). - Toggle/consistency improvements in auto-apply logic (commit: 92f6abaedc30a3ee47c0d84b00f243ed540a039a). Overall impact and accomplishments - Improved enrollment integrity and cache strategy, reducing risk of duplicate enrollments and stale default recommendations. - More reliable license applicability decisions, supporting accurate entitlements and billing. - Expanded unit tests across repos, increasing sustainability and confidence in future changes. Technologies/skills demonstrated - Python backend development, unit testing, and test coverage expansion - Cache invalidation patterns and data integrity safeguards - Plan selection algorithms and edge-case handling - End-to-end traceability from commits to delivered features
