+# Run Gradle tasks against an explicitly-named project and report the result from
+# the exit code, never from the console text.
+#
+# Why this exists: reading "BUILD SUCCESSFUL" out of piped Gradle output is not a
+# reliable signal. A shell chain like `cd dir && cp f . ` followed on the next
+# line by `./gradlew test` will happily run Gradle in whatever directory the
+# shell was already in if the cd failed, and the success line it prints is then
+# about a different project entirely. That failure mode is silent and reads
+# exactly like success.
+#
+# Usage:
+#   gradle-verify <project-dir> <gradle-task...> [-- <extra gradle args>]
+#
+# Exits with Gradle's own exit code. Prints a summary block that names the
+# absolute project directory actually used.
