Semantic Coherence: NOAA โ€“ Signal Evidence & AI Readability

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 semantic drift is maximized by the disconnect between the high-authority signal of a .gov homepage and the actual delivery of a server error. There is no sub-page content to compare, meaning the promise of public utility is completely undermined by technical unavailability. This represents a total failure of the signal-substance alignment, where the expected governance information is replaced by a functional null. The heading hierarchy is entirely absent, precluding any logical story or service path.

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.
