THREE.JS / FOUNDATIONS 311
Own the source.
A deterministic capture stream crosses the browser media boundary, feeds VideoTexture and THREE.Audio, then gets stopped and rebuilt with its ownership visible.
No camera or microphone permission is requested during initialization.
video source lifecycle
Track enabled is a local mute policy; stop() is the terminal lifecycle transition.
permission matrix (synthetic)
Choose a state to classify the expected request outcome without opening a permission prompt.

The texture is recreated when the source dimensions change.
A generated oscillator stream is analyzed after a user gesture resumes Web Audio.
Real camera/microphone access remains an explicit action and is not inferred from this lab.
Generated source is safe to restart · permission matrix is simulated · real devices require an explicit click
