Hidden-State Updates and observable-record composition in retrocausal models
D. M. Theshan N. Weerasinghe
A hidden-variable model can reproduce context-independent individual readouts while failing to preserve observable records when devices are connected or reused. We distinguish two…

Complete Detector Records and Contextual Source Laws in a Retrocausal Spin Model
D. M. Theshan N. Weerasinghe
Detector outcome probabilities can be independent of a later measurement setting even when earlier timestamps, detector seeds, or environmental records depend on that setting. We c…

Adaptive Record Consistency in a Schulman-Type Model
D. M. Theshan N. Weerasinghe
Adaptive measurements test whether a retrocausal model preserves observable records when experiments are connected by classical feedback. We establish exact and quantitative compos…
