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.

A catastrophic drift exists between the Quanterix brand signal and the Forbidden substance provided. No sub-pages were accessible, meaning the homepage promise of a scientific enterprise is contradicted by a total failure to deliver any functional content to the user. This represents the most severe form of semantic drift: a promise of information followed by a technical gate that prevents any alignment between claim and proof.

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.
