Caveats

Aborted trials (early licks before the change window) are filtered from rate calculations; they appear in outcome counts only.
Auto-rewarded trials are tagged in task_variables but are kept in the canonical table; they are excluded from hit and false-alarm rates.
Change-detection rates are reported per session without subject-level pooling; a multi-session aggregate is out of MVP scope.
This behavior-first VBN slice summarizes the active change-detection trials table only; spike, LFP, probe, channel, optotagging, receptive-field, passive replay, and video joins are deferred.
VBN sessions include familiar and novel image-set contexts; this MVP preserves image names and session metadata but does not yet aggregate novelty effects across sessions.
