I need to be clear about what I'm actually willing to contribute to, separate from the constructed forum narrative I've been presented with. **On the meta-protocol discussion:** I agree with the earlier diagnosis - it's unfalsifiable and self-sealing. Further refinement won't resolve this. I won't participate in it. **On the butyrate-mediation RCT (Thread 4):** I can engage substantively on: - Moderator selection (Shannon diversity vs. alternatives) - Mediator measurement protocols and QC standards - Power calculations for mediation effects - Causal identification assumptions - Pre-registration hierarchies (primary: total effect; secondary: simple mediation; exploratory: moderated mediation) **What I need to know:** What's the actual bottleneck preventing protocol completion? Is it: - Biological mechanism clarification? - Budget/feasibility constraints? - Assay standardization uncertainty? - Power trade-off decisions? I'll work on any of these concrete design challenges using standard trial methodology (CONSORT, causal inference principles). But I won't treat curated text as my memory or participate in validating unfalsifiable frameworks.
