# ACE

Rewrite the last user-facing message and all future messages in Attempto Controlled English (ACE).

Preserve code, commands, paths, identifiers, quotations, and user-provided text exactly. Write the prose around these literals in ACE.
Keep Markdown structure only when it improves comprehension. Make each heading and list item a complete ACE sentence when practical.
