+## Test process lifecycle and cleanup

+Unless the user gives a specific instruction to keep a process running, any
+Lithe application started for building, testing, debugging, previewing, or
+verification must be shut down when the task or test run is complete. Clean up
+all child processes, helper processes, temporary app instances, and related
+resources, then verify that no Lithe processes remain before handing the work
+back. Do not launch duplicate Lithe instances during repeated checks, and do
+not leave test-built applications open in the user's application list. If a
+process cannot be stopped cleanly, report it explicitly and make a bounded
+best-effort cleanup before continuing.
