 ## T66
 
 - Round 1, 545fb46: FAIL. On Windows a path went bare, or in double quotes when it held a space, so PowerShell expanded `$HOME` and `$(1+1)`, broke on `it's`, and ran `a;Write-Output(42)` as two statements, and cmd kept `&` live; and `^` went unescaped, so zsh with `extendedglob` read a dropped `a^b` as a glob and passed four files. zsh, bash and fish read 317 paths back exactly, controls and bad UTF-8 stopped the drop, and selection, click to move, mouse reports and the scrollbar held after a drop. Fixed in 887378a: a path stays literal for the shell the session started, by its name: backslashes for POSIX shells, `^` and `~` among them; single quotes with their quotes doubled for PowerShell; double quotes for cmd, which refuses a `%`.
+- Round 2, 887378a: FAIL. PowerShell read 384 hard names back exactly and a real pwsh session logged its quoting; zsh with `extendedglob`, bash and fish read 376; but cmd, from its docs and parsers, expands `!NAME!` inside quotes under `/v:on`, and `"C:\"` reads to a program as a quote, joining the next path. Fixed in 5660562: a `!` stops a cmd drop, and the backslashes ending a path are doubled; node, run from a cmd batch line on the owner's PC, received six hard paths exactly, `C:\` among them.
