Each attachment names exactly one patch step; that step must name draft-patch:<step/id> and the same patch-policy/ref. The host validates all material and derives content addresses before publication. Total decoded written content is at most 1 MiB, across all attachments; enclosing product and evidence budgets also apply. Independent review, plan policy admission and HIL remain mandatory.",
