RCM Programme — Supplementary Evidence Register and Evidential Position Statement

Two supplementary documents for the Return Constraint Model (RCM) preprint (doi:10.5281/zenodo.19652637, latest version). Document 1: Supplementary Evidence Register — the full W2 convergent corroboration structure across five independent methodological branches, comprising 98 individually verified, named published sources within a structural framework sized for up to 198+ items. Document 2: Evidential Position Statement — a precise account of the distinction between Claim A (gate mechanism, structurally established CCT-3 to CCT-4) and Claim B (consciousness criterion, provisionally supported CCT-2, awaiting CADP validation). Together these documents constitute the full evidential basis for the RCM programme as of 2026.
