December 2025 (sustainable-computing-io/kepler): Delivered foundational Power metrics enhancements to enable accurate power metric collection and cross-meter compatibility. Key changes include introducing a dedicated Power type, updating the energy interface to expose Power(), and unifying power calculations across the system. This work also replaced the Power type with a safe, typed Power abstraction to improve unit conversion reliability and reduce errors. Added unit tests and mocks for power zones, validating behavior with both RAPL and non-RAPL meters. The combined effort strengthens power metrics readiness for broader deployment and analytics, enhancing system reliability and developer confidence.
