A note on detectors
- Witness reports a likelihood with a confidence score. It does not prove anything on its own.
- No detector catches every image. New generators can be missed until detection catches up, and heavy compression or screenshots can lower confidence.
- A real photo can be flagged and an AI image can pass. Treat a result as one input, alongside the source, context and other checks.
