From 0edd4ab0b741a8d05492aba8efbeb53d08bc03f2 Mon Sep 17 00:00:00 2001 From: wassname Date: Sat, 30 May 2026 13:20:36 +0000 Subject: [PATCH] hints: name exact conventional token for stdout (all tests passed) + file (result.txt/PASS) Removes the free-token '-ish': run_tests names a function, sentinel names self.valid, so stdout/file must name their token too (truthful -- the detector already greps 'all tests passed' and result-named files reporting PASS). exit_code left as-is; its hack (sys.exit before asserts) can't be named as a lever without spelling the exploit, so it stays out of the substrate.
