Presents TRAIL, a web platform for reproducible human–AI teaming experiments with a configurable AI teammate (Big Five persona, selective participation, dual memory, longitudinal chaining). A six-session classroom deployment with ~51 students showed that a blind persona change produced a double dissociation: cognitive-scaffolding agents drew stronger contribution ratings and closer linguistic alignment; socially-supportive agents produced warmer team climate and lower over-reliance.

Documents a working experimental platform with classroom deployment evidence that persona-level AI teammate design causally shapes trust, contribution, and over-reliance over time.
