+# P5 w1's G3 codec suite. It is registered on its own rather than in the list above because it
+# links gtest, NOT gtest_main: the R-2 Fatal arms report through MGLOG_F + std::abort, so the
+# cases that drive one fork and read the Fatal line back out of a log file the process names
+# before anything logs - which needs a main() of its own (PipeInputsTest's shape). It also
+# reaches MG_Pipe and MG_State, so it carries their include paths.
