June 2026 fboss monthly highlights focused on safety, clarity, and cross-system compatibility. Two primary features were delivered: (1) stronger code quality in the remediation workflow through upgrading type checking from pyre-unsafe to pyre-strict in remediation.py, delivering safer, more maintainable code with reduced runtime type errors; (2) data-model alignment for EEPROM v6 across thrift structs, normalizing PmUnitVersion and VersionedPmSensor field names to match spec while preserving thrift field IDs for wire compatibility. Key changes spanned three commits across the two features, including updates to 12 platform sensor_service.json configs and all affected C++ consumers (Utils.cpp, SensorServiceImpl, ConfigDiffer) and tests. While there were no explicit bug fixes recorded, these changes significantly reduce risk, improve reliability, and lay a solid foundation for future enhancements.
