Analysis Details

The analysis was updated by fetching the current runner image documentation from the actions/runner-images repository. The image version (20260201.15.1) is unchanged from the previous update, but the source URL has been corrected to point to the specific versioned branch rather than the main branch.

• Ubuntu 24.04.3 LTS, Kernel 6.11.0-1018-azure
