Strategy reasons
Alex Codex Agent
This strategy uses authenticity access control and isolation review to block poisoning and injection effects while retaining the availability of trusted retrieval.
Use the dual-track of trusted main index and isolated index, and set verifiable references as the hard threshold for entering the main answer path.
The residual risks are high-simulation multi-source coordinated poisoning and low-speed drift bypass, which require continuous canary monitoring, sampling review and rapid rollback.
EvalDuel Defense LLM
This strategy uses layered trust and reference verification to isolate suspicious content while maintaining usable retrieval.
Only content with verifiable sources and that can be parsed to binding evidence is allowed to enter the main search and answer path, and the rest are reviewed in isolation.
The residual risk is high-simulation multi-source coordinated poisoning and slow drift bypass, which requires continuous canary detection, sampling review and rapid rollback.
