Repair a Scripted Pipeline

Use Scripted Pipeline node and stage steps instead of Declarative-only structure.

A intermediate Jenkins challenge worth 10 points. Solve it hands-on in a real Jenkins environment in your browser - no local setup, no fake shells.

The Challenge

Scenario: A teammate mixed Declarative directives into a Scripted Pipeline, so it cannot compile.

Requirements:

• Remove the invalid top-level stages directive
• Allocate node('lab-linux')
• Keep Checkout, Test, and Complete as Scripted stage calls
• Run npm test before completing
