## TL;DR

Advanced NLP techniques include transformer attention, bidirectional pretraining, and retrieval-augmented generation. This repair maps NLP claims to primary papers.

## Core Explanation

The previous article had source coverage but capped claims. The repaired version aligns fact confidence and evidence to three direct NLP sources.
