Definition. Immutable rollout record [ftip-0051]
An immutable rollout record is a tuple
\[R=(q,\nu _b,\tau ,e),\]where \(q\) is the sampled task, \(\nu _b\) is the behavior-policy stamp, \(\tau \) is the stopped trajectory of Definition [ftip-0025], and \(e\) is the verifier evidence of Definition [ftip-0047]. The tuple records facts fixed when the rollout finishes.
Current-policy likelihood ratios, clipping decisions, reuse counts, and acceptance decisions are excluded because they may change on a later update attempt.
