The user should be able to choose from the last arbiter message alone, without
scrolling back through the owner↔reviewer conversation. Instruct the arbiter, on
ESCALATE, to restate the decision in one sentence and list the options as a
short numbered list with per-option consequences, including only the minimum
context needed. Prompt files are read per-turn, so this is live immediately.
