Across three extended-context models, the authors report dialogue-level hybrid leakage between 38.7% and 54.6%. More topic drift within the tested window did not reliably reduce recovery, framing active-session privacy as a persistent behavioral risk rather than only a training-data or immediate-jailbreak problem.",
