 - Round 2, 96ae85b: FAIL. The permission check raced alacritty's chdir, whose result alacritty ignores; closing a live pty logged nothing. Fixed in fff436c: ELYTerminal's own Unix pty, a checked chdir in pre_exec that fails the spawn, closing and hung-up logs with a test.
 - Round 3, fff436c: FAIL. Drop waited on the program while holding the master, so a program ignoring SIGHUP never ended. Fixed in 0e7f309: the master closes before the wait; a test that traps HUP went red, then green.
 - The review cap of three rounds is reached. The round-3 fix stands on its red-green test, not a fourth round.

+- Round 1, dfaf378: FAIL. fish searched <dir>/fish/fish, so its script never loaded (fish 4 sends OSC 7 itself and hid it); PowerShell's Restricted policy would block the script; control bytes in a folder name broke OSC 7; bash and PowerShell prompts reset $?; install swallowed read errors. Fixed in c2da9dd, each break shown red in a scratch copy.
+- Round 2, c2da9dd: PASS.
