sys.stdin.read(1) on the buffered TextIOWrapper pulls the whole escape sequence into its Python-level buffer, so the follow-up select() sees an empty fd and every arrow/Home/End press degrades to bare Esc; the unread '[B' tail then leaks into the next keypress. Read raw bytes via os.read() and select() on the file descriptor instead, keeping the same key tokens and classifications. Add pty-driven regression tests over a real cbreak terminal covering CSI sequences, single-byte keys, bare Esc, and tail-leak.
