Gate 4 blinded review

The plates are not on this copy of the page. This is the instrument, published so the protocol can be read before anyone spends half an hour on it. The 72 images are 113 MB of full-resolution waterfalls and travel as one file, tracetriage_gate4_bundle.zip, sha256 c426e1d978b66cf62a8d024a: every way of shrinking them changes what a reviewer is being asked to judge. Ask for that file, unpack it, and open this page from the folder it makes. Everything here works except the pictures.

Artifact usable

Can this image be read? Are the axes present, is the frame complete, is it free of the rendering faults that make a spectrogram undecidable?

Visible signal

Is there a trace above the noise anywhere in the frame?

Target consistent

Does any visible trace look like a satellite pass, meaning a smooth curve drifting across frequency, rather than a straight vertical carrier or a horizontal band?

unsure is a real answer and it is the point of the study. Do not guess to be helpful: a guess inflates the exact number this gate measures. There is no back button on purpose, because the 12 repeated items only measure agreement if you cannot look up what you said the first time. Answers are saved as you make them.
