03_draft_blog-building-engineering.md,02_brief_blog-building-engineering.md, and01_research_blog-building-engineering.mddo not exist on disk. Agents 4, 5, 6, and 7 all returned an explicit FAIL → RETURN TO AGENT 1. Agent 5's handoff setsparallel_ready.agent_6: falseandparallel_ready.agent_7: falsewith the verbatim instruction: "Do not proceed to Agent 6 or Agent 7. There is no draft to review for voice. This article must return to Agent 1 and re-run the full pipeline." Writing a meta title, meta description, URL slug, schema markup, or — most critically — an "optimized final article" would require inventing the entire piece. That is fabrication, so it will not be done. No `## Final Article` section is produced because no article exists. There is intentionally no<!-- END ARTICLE -->sentinel below, because nothing here is publishable.
