The composer sent input with pane.write, which writes to the PTY of the tmux client the app spawned. That client detaches (we no longer render or drain its PTY since T-137), leaving the session alive on the server with no client — so keystrokes written to the dead PTY vanished and Claude never saw the message. Submit now goes through the tmux server: load the text into a named paste buffer, paste it bracketed (multi-line and special chars arrive as one block, not a stream of submits), then send Enter. Verified against a live session — paste-buffer -p reaches Claude's input with no client attached. The no-tmux fallback still uses pane.write (claude runs directly in our PTY there).
