Jul 1, 2025July 2025 for PowerGridModel/power-grid-model: Key data accuracy and maintainability improvements. Bug fix: corrected branch3_3 current sensor data retrieval by updating input processing to reference side_3. Documentation and test dataset enhancements to streamline onboarding and macOS build validation. Internal code cleanup introduced a private naming convention for minimum fields and components, improving readability and preserving existing validation behavior. These changes improve data reliability, reduce onboarding time, and enhance long-term maintainability.

Jun 1, 2025June 2025 monthly summary for PowerGridModel/power-grid-model: Focused on documentation and clarity improvements to reduce misconfiguration and improve onboarding, with explicit notes on batch processing semantics. Implemented two targeted updates across README.md and batch_dispatch.hpp to clarify subscription instructions and batch behavior (zero-scenario batches are independent but not topology cacheable). No customer-facing changes; improvements target maintainability, correctness, and developer experience.
