// FLAGS TYPED AFTER THE BRIEF REACH A SHELL RUN'S CHILD AS FLAGS. Since the
// parser started reading a trailing ceiling (#1700), `codeaf senior-dev
// "brief" --max-cost 0.5` in a repository said `up to $0.50` and then died:
// the child line kept the person's order, the folder step took its last word
// for the brief, and the note saying where the copy is landed between
// --max-cost and its value, which the child refused to parse. Whatever order
// the person typed, the child reads back the same ceiling, works in the copy
// rather than the person's --dir, and is handed the note ahead of the brief.
