 ### Behavior crafting
 
 Octane includes a behavior explorer for defining measurable policy properties. While watching an episode, press `b` to capture a scenario — mark which actions you want (positive weight) or don't want (negative weight) at that traffic state. Name it, and Octane saves the behavior to `~/.highjax/behaviors/`. The next time you run `highjax-trainer train`, all discovered behaviors are evaluated every epoch and their scores are recorded as `behavior.{name}` columns in `epochia.parquet`.
