+macOS uses one OS version with one native baseline job per architecture. Each job
+runs package and Inspector checks after a single dependency installation. The
+separate Inspector matrix covers Linux and Windows; Apple artifact checks retain
+their own macOS 15 arm64 job for Xcode-dependent workflows.

 These native baseline checks complement the Linux source-test shards and the
 separate Apple-artifact and real-provider lanes. Actual Hopper, Ghidra, IDA,
 browser and managed-tool claims require their corresponding verification lanes.
