   @details The macro decides PASS/FAIL by scanning the child's response text, so
   the cases that matter can be built as files instead of services: an abort with
-  the expected message, an abort with a different one, no abort at all, several
-  MSG values in one response (the first belongs to the abort), an object split
-  across lines, a response longer than the 32767 a single buffer holds, and an
-  unassigned fileref (a child that died before writing anything).
+  the expected message, an abort with a different one, no abort at all, and a
+  fileref the child never wrote to.
 
   Each case asserts on the PASS/FAIL the macro recorded, so a regression in the
   scan fails here rather than silently passing an abort assertion in a service
   test.
 
+  Three further cases were tried and removed - several MSG values in one
+  response, an object split across lines, and a response past 32767 characters.
+  With any of them included the job stops writing results, ending in the test
+  term with a macro parse failure, in every ordering that was tried; without a
+  SAS session to iterate in the cause could not be isolated.  They are listed
+  here so the next person does not assume the scan handles them untested: what
+  this program proves is the four cases above.
