Month: 2025-05 Overview: Focused on reliability and correctness improvements in the sail-operator repository, with a targeted bug fix that improves how revision usage is determined. No new user-facing features were introduced this month; instead, the emphasis was on accurate state calculation, test coverage, and code quality to support stable deployments and better decision-making in release gating. Key accomplishments: - Implemented a bug fix to skip completed pods when determining revision usage, ensuring accurate revision in-use status and reducing erroneous deployment decisions. - Added unit tests to cover the new behavior, increasing test coverage and confidence in correctness. - Maintained a fast, low-risk change with focused scope and clear traceability to issue #842, with a single, well-defined commit. Impact and business value: - Improves reliability of revision usage calculations, enabling safer rollouts and rollbacks, and reducing operational risk in multi-revision deployments. - Enhances observability of deployment state through deterministic unit tests, facilitating faster CI feedback and healthier release cycles. Technologies and skills demonstrated: - Go-based unit testing and test-driven improvements - Code correctness and regression risk management - Issue-driven development with clear commit traceability to #842
