+- Defer BufDelete handler to ignore buflisted changes from scope-nvim
+scope-nvim scopes buffers per tab page by toggling buflisted on
+  TabLeave/TabEnter. Setting buflisted=false fires BufDelete, which
+  pterm's handler interpreted as a true buffer deletion—calling
+  M.detach(), killing the bridge (SIGHUP/129), and wiping the buffer.
+
+  Defer the BufDelete callback with vim.schedule and check whether the
+  buffer is still valid and loaded. A merely-unlisted buffer survives
+  the check and the connection is preserved; a truly deleted buffer
+  triggers detach as before.
