An agent picks the right entity at step 1 then silently binds to a different one later. Measured over 200 workflows and 580 binding-scored steps across eight model backends, it occurs naturally in 18% of eligible workflows (arXiv 2607.18316). The intuitive mitigation, persisting the first binding as an entity lock, amplified wrong actions 3.0x on average and 8.5x on Claude Opus 4.5, because it cements early mistakes. What worked: a single cheap second model call that re-reads the original instruction before acting, cutting wrong actions 79% and landing within 1 point of the oracle upper bound.
