March 2026 monthly summary for chimera-linux/cports: Stabilized the Waydroid container service integration by correcting the start/stop command syntax, preventing intermittent service failures and improving reliability of containerized workflows within the package. The fix reduces debugging time for developers and lowers support touchpoints for CI and user deployments dependent on the container lifecycle. Implemented as a focused bug fix in the cports repository with a single, targeted commit addressing unbreakage of the container service. This aligns with upstream efforts to keep container tooling compatible and maintainable.
