Termination
Why a decision episode ended — recorded on every emitted transition, because that it ended is not enough to interpret the last row (§4.6.3).
NATURAL is the modeler's declared terminal condition becoming true: the modeled system reached an ending it defines. MAX_EPOCHS is a declared cap on decisions. RUN_LENGTH is the replication ending underneath a sequence that had not finished. MODEL_STOPPED is the run being stopped from outside. POLICY_ERROR is the rule throwing, which is not caught.
The distinction matters beyond bookkeeping: learning algorithms bootstrap differently from an episode that terminated than from one that was merely truncated, and conflating the two is a known source of bias.
