From 015152bb7e28a26d135fc4bc67b09a5f53d5080b Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Mon, 28 Sep 2026 20:51:06 -0300 Subject: A shell that exits under a run answers exit N, and the log says exit before del A dogfood agent ran `exit 3` through pty/run: the reader got ENOENT, and the log went straight to del. The hosts now read a shell's exit status at its pty's end as they do a command's; a run waiting on the line answers `exit 3` with what it printed, the log says `exit 3` before the pane's `del`, and an open run still stats after its pane is gone (cat fstats its input). Pins cloud9 f35b7ed, whose stat of an open fid names its open. Writes to a gone pane's pty/data, held open or not, fail ENOENT.
