November 2025: Stabilized the CLI experience in checkly-cli by fixing the status bar behavior during log streaming. Resolved an issue where the status summary overwrote live log messages, ensuring the status bar remains anchored to the bottom while logs stream above it. Delivered a targeted fix that improves real-time log visibility and reduces user confusion during streaming sessions. This work reinforces a pattern of ensuring UI elements do not disrupt critical log output in the CLI and contributes to overall tooling reliability for developers during interactive sessions.
