Month: 2026-01 highlights focused on security-hardening of Libvirt access, CI visibility improvements, and automation of OracleLinux CI. In seapath/ansible, I implemented policy hardening for Libvirt admin access, standardized live migration ownership via a dedicated libvirtadmin user, and ensured group-based Libvirt socket access with a playbook fix to run distro detection before role application. I also enhanced CI to generate and upload test reports for GitHub Actions. In seapath/ci, I introduced an OracleLinux CI automation script that downloads sources, runs tests, and generates reports, and aligned with GitHub Actions by removing manual test report uploads and transitioning to automated handling.
