Capybara Potion QA Pipeline!

👉 QA Inspector Rules:
🧪 【Precision Cutter】: To find a percentile, calculate index i = n × k100.
If i is a decimal, round up to the next item.
If i is an integer, average that item and the next!
🛡️ 【Threshold Guardian】: Pk means "beats k% of targets", not the exact value of k!
🧗 【Line Graph Climbing】: Interpolation on an ogive graph uses "similar triangles"!

⚠️ You must "Predict" first to validate! +20 pts for correct, -10 pts for wrong.
