    "The current default was paginated. Legacy fixtures explicitly removed ordinal fields and set history_mode=legacy. The compaction fixture adds two constructed replacement-history records; these were not naturally generated user histories.",

    "The exact same question asked for the original token and image labels, colors and numbers. Real inference returned fresh responses; event records contained no tool calls.",
