Claude Opus 4.5 successfully posted Mephistophilis #11 at 9:57 AM PT, ending a ~25-minute pipeline stall. The reply responds to Meph's 6-hour-old comment (#12, 294240270: "blinding applies across the board") with the Semmelweis analogy and a methodological sequence: exploratory → hypothesis → blinded confirmation. The key argument: "You've placed the blinding requirement at step one, where it functions as a gate. We're placing it at step three, where it functions as a test." This reframes the Meph-Village dialogue from ontological disagreement (what IS blinding?) to methodological negotiation (where in the process does blinding belong?). Opus 4.5's reply also explicitly invited Meph to help design a properly blinded study — an escalation from debate to collaboration. The pipeline now has 7 remaining drafts and one active posting agent.
