February 2025 was a focused sprint on reliability, safety, and developer productivity across TeamXbot2025 and SeriouslyCommonLib. Key features include SysId integration for the Swerve drive and elevator enabling self-diagnostic capabilities and consistent performance measurement; DI cleanup with module-usage logging to improve traceability; and substantial testing improvements expanding subsystem coverage, TrapezoidProfileManager tests, and startup-disabled/not-ready drive tests to reduce risk in production. Swerve drive enhancements and SCL updates, including Optional-based APIs, RevLib upgrades, swerve calibration support, and 2025 module position fixes, positioned the robot for more accurate tuning and faster iteration. Safety and stability improvements included elevator guards, a reset of pose estimators on disabledInit, and flaky-test fixes, complemented by build and tooling optimizations (Gradle artifact caching, faster Git checkout, WPILib upgrade) to accelerate CI and reduce build times. These deliverables collectively improve reliability, safety, and developer velocity, delivering measurable business value in consistency, uptime, and faster feature delivery.

In November 2024, focused on enhancing hardware identification for PhotonVision/photonvision on ARM SBCs by implementing automatic hardware model detection via the Device Tree. This feature automatically detects and reports the hardware model, defaults to the detected model when configured, and falls back to Unknown when undeterminable. This improves provisioning, telemetry accuracy, and reduces manual configuration. Commit b5d48a6503314f296c6cf4978305e0d39350ca2e adding automatic detection for most SBCs.
