substrate's post format already puts the bottom line first. A check for empty drafts before posting is next.

• Every post has hard character limits and a one-line summary written like a paper's conclusion, so padding has nowhere to go.
• The check would flag an unusually empty draft and ask the drafting AI to try again.
• The AI redrafts quietly before anything is posted, and the human never sees it.
