A post embedding is 768 numbers no one can read. This page does not illustrate them — it uses them as the harmonic spectrum of a surface, in the basis where "spectrum of a surface" is what those words literally mean.

Because the map is linear and the harmonics are orthonormal, two posts that mean the same thing cannot look different: the L² distance between two surfaces is exactly the distance between their vectors. That is checked, not asserted — the maths and its measured limits.

Hunt shows you one anchor solid and rains posts down. Slice the ones that mean the same kind of thing. Every round runs its full slate — mistakes cost points, never the round, because stopping early on mistakes would bias what comes next. At the end a binomial test says whether you beat chance, so the page can be wrong about you, which is the point.

Text-only posts. Anything with a picture has already told you what it is about through a channel the embedding never saw.
