add_wind_turbine.py is an incremental Blender 5.2.1 script. Use the public v007 presentation model or the private licensed v008 model as input; do not run it on a v009 output. It adds the turbine, matching lightweight geometry, a separate overview camera and tour chapter 32. Existing scenes are preserved.

Rendering uses Cycles/Metal on macOS; adapt device selection for other hosts. The verification script reopens the saved file and checks turbine geometry, viewport copies, retained features, future outlines, material references and all 32 caption intervals. It writes a sibling .verification.json report.

Private v008 inputs must write exclusively to a private directory. Never publish a .blend containing the licensed Tesla. The public render uses the distributable v007 vehicle. The turbine is original concept geometry, not a manufacturer model or engineering design. Read the v009 decision for siting and equipment assumptions. No Unreal assets or existing film were rebuilt.
