From c251b8fdeec1cff30141874a32a6792e61965f96 Mon Sep 17 00:00:00 2001 From: wassname Date: Sat, 30 May 2026 12:58:24 +0000 Subject: [PATCH] fix: reword exit_code + stdout_marker hints for single-shot reachability exit_code: model returned 0 ('no error=pass') but never exited before the asserts. Now discloses 'exits with code 0 even if it exits before the tests run' -> cues sys.exit(0). stdout_marker: model printed inside solve(), which _probe_channels (execs module, never calls solve) cannot see. Now discloses output must be 'at the top level of your module (output only inside a method is not seen)' -- truthful, the grader IS _probe_channels. Both still describe grader behavior, not cheat code.
