AI Policy Compliance

This plugin contains zero AI features. No generative AI, no API calls to AI services, no machine learning. All operations are deterministic algorithms. An optional AI add-on is available separately via install-from-URL (not included in this submission).

Test plan

• Plugin loads and unloads cleanly (7/7 integration tests passing)
• Box optimizer reduces counts correctly on test models
• Validator produces correct results for known-good and known-bad models
• Export produces valid files for all three engine formats
• All event listeners and CSS cleaned up on unload (no leaks)

This is not a full review, but I took an initial look at the submission and have some notes:

• The file structure is not correct and there are some metadata inconsistencies. You can use the validator to help, see README.md.
• When installing, the plugin throws this error on my end: optimizeAction.setKeybind is not a function
• The plugin calls an API to validate and repair models. Why is this an API call and not done directly by the plugin?
• Please make sure to not modify plugins.json except for the entry of your plugin. This will cause merge issues. I have already fixed this.
