During November 2024, Natalia Langa focused on enhancing the reliability of SLO History reporting within the nobl9-go repository. She addressed a critical bug by implementing robust validation logic for time frame options, ensuring only valid time units and counts are accepted for both rolling and calendar frames. Working primarily in Go, Natalia introduced comprehensive date range checks and enforced strict input validation at the API and backend layers. This work reduced the risk of inconsistent analytics and improved data integrity for SLO History reports, resulting in more trustworthy dashboards and supporting better business decisions through reliable backend data processing.
