+# which runs every member on every platform with it. The release changes no
+# descriptor grammar. A dependency's BMIs now lie below its package's
+# directory, and every unit of an ELF target is compiled with -fPIC, so every
+# member is compiled once more and its global cache entries are refilled; no
+# check here reads a BMI path.
