June 2025 Summary for Solvro/testing-course: Delivered a critical bug fix to supervisor availability, enforcing a strict 3:00 AM–5:00 AM window. This ensures availability checks cannot extend into 5:01 AM and beyond, eliminating edge-case scheduling issues. The fix is implemented in a single commit: 8a362994a34b190b7a565de1b1b9bb4df7f49e61 with message 'fix: supervisor availability check logic'. Business value: reduces scheduling conflicts, improves policy compliance, and enhances user trust. Technical impact: refined boundary validation in the backend, improved testability and traceability, and reduced risk of downstream failures in scheduling workflows. Repository: Solvro/testing-course.
