 No validation that count is >=1 before entering the loop; the initial success value is never overwritten when the loop body never executes.
 
 ## Fix
-NOT YET FIXED. Recommended: reject count<=0 with an explicit error instead of falling through to a silent vacuous success.
+hello's -c is parsed with cmdutil_parse_long() and must be >= 1; 0, negative or non-numeric is a usage error.
 
 ## Verification
-_Not recorded (migrated from buglog.json)._
+- Test: test_hello_nonpositive_count_rejected in src/harness/testsuite/test_test_cli.c: RED before the fix (exit 0, nothing sent), GREEN after
+- Suites: harness 6/6 (asan): harness_unit_test 141/0, cmdutil 14/0, resval_typeresolve 7/0, joblist_display 22/0, join_worker_args 7/0, listrow_json 12/0
+- Live: n/a; xce_test is a client tool and every case above runs without a controller
