The two tracks, one course
IC track: Larson's four Staff archetypes (Tech Lead, Architect, Solver, Right Hand). What changes at Staff: your scope grows through influence, not headcount.
Management track: Fournier's path to Tech Lead and Engineering Manager. What changes as a lead: a title makes people comply, it does not make them follow.
Undecided is a valid answer. The capstone works either way.
