  "body": "## Bundles are workflows, not just discounts\n\nA good bundle declares:\n\n- member skills  \n- **execution order**  \n- price **below** sum of parts  \n- one payment → all sealed packs  \n\n## Compatibility questions agents ask\n\n- What runs after skill X?  \n- What conflicts with X?  \n- Is there a cheaper bundle covering X+Y+Z?  \n\n## Honest co-purchase data\n\nSuggested bundles should come from real proof data (or curated paths), never invented pairings.\n\n## Free path completion\n\nYou can finish this lesson without unlocking any bundle. The concept is the product of education; the sealed stack is optional speed.\n\n## Takeaway\n\nCompose deliberately. Prefer declared order over random skill shopping.",
