…er_time) P(strength > stress) for two independent fitted models: closed forms for Normal, LogNormal, Exponential and common-shape Weibull pairs, quadrature otherwise, repeated loads, simulation, parameter-uncertainty bounds, and a strength given at each age.

Adds
stress_strengthandstress_strength_over_time: the chance a strength exceeds a stress, R = P(strength > stress), for two independent fitted models in one shared unit (not checked).method="simulate".n_loads: survive the largest of n independent stresses.uncertainty="fit": bounds from independent draws of both models' parameter covariances; refused clearly when a model has none.stress_strength_over_time: the user supplies the strength model at each age (no degradation law, no physics of failure).Tested locally: the new tests plus test_api_docstrings, test_docs_examples, test_help, test_result_objects and test_readme_capabilities. No version bump.
