Related helpers check whether a type's instructions file is verified as belonging to that type and release, and wrap or trim page content using `<...page tag...>` markers, dropping content that would exceed a set byte budget.\n\n**Why**\n\nThis keeps Artifact type instructions accurate and within size limits, and steers writes toward the type's proper data store rather than direct file publishing.\n\n- Area: Artifacts\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 1\/5"}
