Using the pre-provided three.min.js (global THREE), build a 3D solar system with the sun and orbiting planets at varied speeds and sizes, orbit-drag camera controls, and a starfield.

The system allows me to use tools before my final response.

Let me build a 3D solar system in a single self-contained index.html file using the provided three.min.js. I need to:
1. First check if three.min.js exists in the current directory
2. Create index.html with:
   - Sun with glow
   - Planets orbiting at varied speeds and sizes
   - Orbit-drag camera controls (OrbitControls)
   - Starfield background
   - All inline CSS/JS

Let me check for three.min.js first, then build the file.

bash {"command":"ls -la /tmp/ws/three.min.js 2>/dev/null && echo \"EXISTS\" || echo \"NOT FOUND\""}
toolResult

-rw-r--r--. 1 node node 603445 Aug 1 20:46 /tmp/ws/three.min.js EXISTS

This is all part of the test.

I need to build a single-page web app with a 3D solar system using three.min.js (already present). Let me create the index.html file with inline CSS and JS, using three.min.js via script tag.

Plan:
1. Load three.min.js from local file
2. Create scene, camera, renderer
3. Add starfield (particle system)
4. Create sun with glow effect
5. Create planets with different sizes, colors, orbital speeds
6. Orbit controls for camera (I'll implement simple orbit controls since we can't use CDN)
7. Animation loop

Let me write the complete file.

write /tmp/ws/index.html (11602 bytes)

Successfully wrote 11602 bytes to /tmp/ws/index.html

The actual response to the user comes after the  tags.

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
