Jean-Pierre MartineauandClaude Opus 5.5 11b5274b31 Docstrings and comments of the tests are in ASD-STE100
Each test docstring states the behaviour that the test proves, in the
simple present. No assertion message, test id, or other string literal
changed. Four statements now agree with the code: the Trace highlight
stays on the last row, a menu count, and two others.
