The composer's settings row is outlined bubbles opening round menus, and the message box is a TextFieldValue so anything put into it without being typed -- a draft, a share, a slash command -- leaves the cursor at the end. A tap that puts a text selection away no longer also collapses the card the text was drawn in: every open and close on the session screen goes through one guard that spends such a press on the selection. The usage bar and the usage dialog were two polls of one measurement and disagreed for up to a minute at a time; they are one feed now, and the countdown rounds up to the minute in the one place both read. A working directory typed as ~/repos/ai-app was four literal characters on the local transport and as an argument on both, so the existence check refused every home-relative path. It is checked by entering the directory now, expanded for a local spawn the way the remote shell expands it, and stored short so the phone draws what somebody would write.
