Semantic Coherence โ€” 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.

The homepage H1 is Access Denied, which provides no service signal to compare against sub-page content. This total messaging vacuum prevents the measurement of semantic drift but results in a maximum penalty for heading hierarchy coherence. No logical story or service structure can be inferred from the single available page, as the user is immediately blocked from the content.

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.
