Preregistered simulation study: ablation of only the cross-branch coherence of a central-spin record state, localizing which coherence class a redundant quantum record needs.
Preregistered re-analysis of frozen simulation rows. When the coherence between the two branches of a central-spin record state is progressively ablated, does the record plateau die at a threshold - most configurations losing it at essentially one dose, the survival curve falling in a single step - or does it erode gradually across the dose grid? This study judges that one functional on the frozen rows of an earlier branch-coherence ablation study (132 configurations, five ablation doses): whether plateau deaths are concentrated at a single onset dose. No new simulation.
A collection of preregistered studies on how records form and persist: simulation studies of redundant information records in quantum toy models (central-spin and spin-chain systems) and of counting laws in causal sets, together with secondary-data reanalyses of human experiments on cooperation and on near-threshold visual perception. Each linked project carries its own preregistration; the registration of record for every study is the time-stamped, DOI-bearing registration linked from its project page. All study designs and analysis criteria were frozen before analysis.
