 - [x] T29 Inside herdr the right column follows herdr's focused pane, which the owner found frozen: herdr keeps its panes' OSC 7, so on macOS and Linux ELYTerminal reads the folder from herdr's socket while herdr's client runs in the session's foreground.

 - [ ] T31 Release v0.1.2 with T29 and T30: version 0.1.2; the macOS disk image, the Windows zip and the Linux tarball, each from its script; the notes say it fixes herdr compatibility and keeps the window's size.

 - Round 1, 3e30f95: FAIL. A shell that ran `exec herdr` kept its process group, so the session never looked at its foreground again and the panel stayed where it was; a relative `HERDR_SOCKET_PATH` was looked up from ELYTerminal's own folder, not the client's, so no socket answered. Fixed in 2af45cb: the foreground is its group and the executable its leader runs, a program that did not read is tried again, and a relative socket lies in the client's folder (`/proc/PID/cwd`, `proc_pidinfo` on macOS); on Linux an executable an update replaced still names itself herdr.
 - Round 2, 2af45cb: PASS. The reviewer ran real herdr 0.9.5 under the native view: a direct start, a delayed exec, a relative socket, both at once, and a folder with a space and an é each gave the folder events herdr's own snapshot named. CI run 988 on 3e30f95 and run 990 on 2af45cb passed on macOS, Ubuntu and Windows.

+- Round 1, 1bf420c: FAIL. On X11 a maximized window, minimized, wrote the screen's size, since gpui's X11 window calls a maximized window unmaximized while it is hidden; and the window could be dragged under the 100 by 100 the settings keep, so a smaller size was refused and lost. Fixed in 2f58a06: a hidden window keeps the size from before, and the window is no smaller than 100 by 100.
+- Round 2, 2f58a06: FAIL. A size the window took just before something covered it was skipped while it was hidden and never read again once it showed. Fixed in 9729d24: a window that shows again is read again; and the window opens centered at whole points, since macOS grew a window whose centered edge fell on a half point by a point, so a kept 900 by 600 had opened at 900 by 601.
+- Round 3, 9729d24: PASS. The reviewer replayed the cover on macOS through gpui and AppKit, against the parent too, and saw the size kept once shown and the restart open at it; the window opened at its kept size and a move wrote nothing; on X11 a maximized, minimized and restored window and a resize minimized at once kept the right size, and the 100 by 100 minimum held. CI runs 993 on 1bf420c and 995 on 2f58a06 passed on macOS, Ubuntu and Windows; run 996 on 9729d24 passed on Ubuntu and Windows.
