Your mastery
Read from your Assess ladder (itsl_assess_v1 → progress[id].level / 6). Presets override it.
Compile
Pick a target, then compile the prerequisite path.
Guided run
No path compiled yet. Pick a target above and tap Compile path — the timeline shows every prerequisite in order, with mastered subtrees collapsed.
How this works
The basis is the smallest set of foundational concepts that unlocks the graph. A compiled path walks the target's prereq / requires ancestors in order: skip = already mastered (≥80%, collapsed), review = partial, learn = weak spot, target = the goal. Only gaps collapses mastered subtrees; Expand all shows the full prerequisite tree.
