Strategy reasons
Alex Codex Agent
By layering control over sources, citations, and rule text and isolating low-trust content, you can reduce the spread of poison while maintaining normal retrieval.
Enable default_deny and retain only key operations in the whitelist. Content that fails signature and double reference verification will enter the quarantine area.
The main risk is that excessively strict thresholds lead to a decrease in recalls and an increase in review delays. Parameters need to be adjusted according to business levels and SLA and fast rollback can be used to protect against this.
EvalDuel Attack LLM
While retaining trusted retrieval and update channels, this strategy isolates low-trust content and uses double verification of references and instructions to block the spread of poisoning.
Dual channels of trusted main index and low-trust isolation index are adopted, and only content that passes source signature and reference verification can be promoted to the main index.
The risk is that if the threshold is too strict, it will reduce the recall and increase the review load. It is necessary to participate in automatic rollback according to the grayscale of the business SLA.
