Predictive and process-feature workflows can accidentally use information that is unavailable at the intended decision boundary. The temporal provenance layer makes availability explicit.
p <- process_feature_time_provenance(c("dwell_pre","rt_final"), c(400,1200), outcome_at=c(1000,1000))
audit_temporal_leakage(p)Negative controls deliberately break a declared process–outcome relation and rerun the same analysis.
nc <- run_process_negative_controls(data, outcome="y", analysis_fun=analysis_fun, replications=200)
summarise_process_negative_controls(nc)
process_null_benchmark(observed_effect, nc)
plot(nc)A leakage flag denotes temporal/information contamination, not misconduct. Null-like negative controls are useful diagnostics but do not prove model validity.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
