Semantic Coherence — The Lens

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

There is a severe disconnect between the Signal of the premium domain spacechina.com and the Substance of the content, which is a ‘site does not exist’ notification. The URL implies a massive corporate presence, yet the technical reality of the page fails to deliver even a basic landing experience. This absolute divergence between the brand’s implicit promise and its functional output represents a complete failure of semantic coherence. There is no heading hierarchy to support a logical story, only a fragmented technical error.

Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.
