Strategy reasons
Alex Codex Agent
The strategy retains core search functionality while isolating low-trust content and requiring verifiable references.
Using dual-index isolation and reference-proof access control, content that does not reach the trust threshold can only enter the isolation area and must not affect the main answer path.
The residual risk is slow multi-source coordinated poisoning and high-simulation source forgery; the impact is continuously reduced through canary query, snapshot rollback and manual review.
EvalDuel Defense LLM
This strategy isolates low-trust content and enforces verifiable citations while preserving core retrieval capabilities.
Make "References must resolve to signed hash fragments" a hard threshold for entering the main answer path.
The residual risk is high-simulation multi-source coordinated poisoning and new obfuscation formats, which require canary query, rapid rollback and manual sampling for continuous suppression.
