+The macOS `macos-named-regressions` CI job now runs `test/regression-issue3680-ubicloud-bsd-userland.test.ts`, so the ubi-runner cases for #3680 (bsdtar) and #3679 (macOS awk) run on a real Mac against `/usr/bin/tar` and `/usr/bin/awk`. Before, the file ran only on Linux CI, where bsdtar and one-true-awk aren't installed, so every case skipped and a regression in either could merge green. A new wiring test fails if the macOS job stops naming the file.
