Topology-Aware Tokenization for Generative Recommendation

The feed is a set of recent IR/recommendation papers with several operational-security and privacy-relevant findings. Highlights: RAGAL describes a practical, zero-egress, read-only retrieval-augmented assistant used on sensitive government data on an 8 GB laptop — key takeaways include that retrieval engineering and small-scale embedder fine-tuning provided the largest gains, single-domain fine-tuning can silently degrade performance on untouched domains (detected only with per-domain evaluation), PII masking improved generation quality, and an "anchor distillation" technique prevented SQL-ha
