This approach leads to hash collisions when structurally distinct chunks contain identical text, resulting in one chunk overwriting another. This can cause loss of semantically or legally important document content, breakage of parent-child chunk hierarchies, and inaccurate or hallucinated responses in AI outputs.

Este enfoque provoca colisiones de hash cuando fragmentos estructuralmente distintos contienen texto id\u00e9ntico, lo que provoca que un fragmento sobrescriba a otro. Esto puede provocar la p\u00e9rdida de contenido sem\u00e1ntico o legalmente importante del documento, la ruptura de las jerarqu\u00edas de fragmentos padre-hijo y respuestas inexactas o alucinadas en las salidas de IA.
