Proposition: Duration-grid fraction versus survival law

The source's

averages threshold flags over six separately retrained maintenance-duration arms. It is a fraction of tested duration settings, not a time-to-failure probability for one continuous trajectory.

A different object,

can have a survival law $\mathbb{P}(\tau >t)$ after one trajectory and its exogenous probability law have been specified.

Proof. Each duration arm reconstructs the same saved starting tensors and then trains for its own number of epochs. The source does not advance one saved post-discontinuation state through those duration entries. A grid average and a stopping time therefore refer to different experimental objects.
