The Roommate

Trains: Steelman

A 5-minute decision story: dishes in the sink, 1am guests during your heavy night, and a note on the fridge you don't remember writing. Three choices, your reasoning recorded — and a debrief that names the mental model: steelman.

Episode 1, The Swap, is free — no account needed. Episodes 2–6 are included with the paid Trailblazer plan.
