Violation of cohesion
If a suspicious paragraph is removed, the surrounding text closes perfectly without losing the logic of the narrative.
Structural independence
The main sign of a splice is its semantic isolation. Read the first neural network paragraph (Block A), and then immediately skip to the third (Block B), skipping the story about the howling HR department. The text will glue together perfectly: "...ensures maximum transparency. Thus, the innovative algorithms...".
This happens because the AI generated its text entirely and self-sufficiently. A human simply "pushed apart" the ready-made paragraphs and inserted their own, like an implant. In a fully human text, deleting a whole paragraph breaks the logic of the narrative, as thoughts flow organically from one another.
