Structural Predictions from Epistemic Isomorphism: A Pre-Registration

Restricted version. Contains the pre-specified measurement thresholds required for falsification before data inspection: effect size metric for "statistically indistinguishable" (P1), operational definition of discontinuity — inflection point in first derivative of discovery curve (P3), and percentage threshold for "marginal improvement" relative to orthogonal baseline (P4). Also contains the full five-step validation protocol: threshold pre-specification → operationalization mapping → application of falsification criteria → per-prediction classification (confirmed / disconfirmed / indeterminate) → mechanism status update procedure. No threshold may be introduced or adjusted after data is examined. The open version (same DOI) contains the mechanism, predictions, and falsification criteria without measurement thresholds or validation protocol.
