+macOS also requires Apple's Swift compiler through `xcrun` for process
+ownership inspection. REA compiles its packaged, narrow process-inspection
+helper into a private temporary directory before a capture or owned provider
+process starts; the same prerequisite applies to owned provider-process
+supervision on macOS. REA removes that directory when it exits. REA does not
+install Xcode, Command Line Tools, or other software. Capability checks prepare
