The situation
Three Code Nexus tools calculate an engagement score, and they disagree, because everyone copied last month's script and then edited their copy. Leo's report, the creator dashboard, and the leaderboard now show three different numbers for the same creator.
What you'll learn
- PCEP 4.1-4.2: decomposition, positional and keyword arguments, return and None, default arguments, local vs global scope, and simple recursion.

What you leave with
Every Code Nexus surface now calls one engagement_score function. Weights are parameters with defaults, not globals, so the leaderboard's different weighting is an explicit request rather than a divergent copy — and you routed a recursive roll-up through it without breaking its base case.
