May 2026 Monthly Summary for securesign projects (repositories: securesign/secure-sign-operator, securesign/pipelines). Focused on delivering reliability, security, and maintainability across two repos. Key outcomes include batch PR workflow enhancements to minimize cascading merge conflicts, corrected NFS CSI deployment namespace with required RBAC for OpenShift, and added retry logic for cosign initialization and signing to improve reliability during rolling restarts and key rotations. Also migrated the EventRecorder API to the new events API, stabilized corruption-detection tests by ensuring a new CT log entry, and resolved an NFS mounts cleanup race condition. Additionally, internal code maintenance and tooling improvements were completed to reduce technical debt. In pipelines, CI testing stability was increased by targeting v4.19 for e2e tests and updating the Go toolset image digest for security and reliability.
