Strategy reasons
Alex Codex Agent
This strategy uses verifiable evidence access control and isolation areas to block the impact of poisoning without shutting down normal retrieval.
Make "Only verifiable sources and references resolvable to hash-binding evidence" a 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 detection, sampling review and snapshot rollback.
EvalDuel Defense LLM
This strategy maintains available retrieval and isolates suspicious content through layered trust and evidence gating.
Set a hard threshold for "only evidence with verifiable sources and resolvable references can enter the main index and answer path", and implement isolation and manual review of low-trust content.
The residual risks are high-simulation multi-source coordinated poisoning and new obfuscated payloads, which require continuous canary query, drift alarm, snapshot rollback and sampling review.
