WHY IT NEEDS A POLICY

Why vfx_fade_in needs a policy

The tool applies a visual effect (fade) to video, which creates or modifies video data. This is a Write-category operation because it transforms media reversibly—the effect can be removed or adjusted. It does not execute arbitrary code, delete data, or produce side effects beyond the intended video modification.

From the tool's definition Tool name 'vfx_fade_in' and description 'Fade in from black' indicate creation/modification of video content by applying a fade effect. This is a reversible transformation that modifies the video output.
