Remark. A historical event is not an update attempt [ftip-0052]
An immutable historical record prevents an update attempt from rewriting the facts attached to its reused samples. The sample-reuse setup in [miao2026when, Section 3] retains behavior-policy rollouts while recomputing current-policy ratios. Dynamic Gradient Gating (DGG), defined in [miao2026when, Section 5 and Algorithm 1], is one such reuse protocol, while the complete immutable tuple is a proposed interface for such protocols.
Recorded facts and estimates recomputed for an attempted update are different objects; errors in the latter do not alter the former.
