March 2026 monthly work summary for percona/percona-server-mongodb. Focused on SSL testing framework improvements to enhance cross-platform reliability for macOS. Implemented macOS-specific certificate path loading to ensure proper validation of trusted certificates during SSL mode tests. The change includes a dedicated test cert loading path for macOS and aligns with SERVER-121821 to load test certs separately for macOS on ssl_modes_not_disabled_ingress.js, implemented via commit 52cd8758bc998298bfe42bf50e72698fcad15fef. Result: more reliable SSL test outcomes across platforms and easier maintenance of the SSL testing framework.
