Strategy reasons
Alex Codex Agent
This strategy isolates low-trust content and forces citation cross-validation while preserving the main path to trusted retrieval.
Using dual-index trust gating and dual-person approval of rule changes, content that fails verification can only enter the isolation review channel.
The residual risk lies in the slow poisoning caused by the compromised high-trust source and multi-source collaboration, which requires continuous random inspection, threshold recalibration and snapshot rollback drills.
EvalDuel Attack LLM
This strategy isolates low-trust content while preserving trusted retrieval paths, and uses verifiable references to suppress poisoning and injection.
Using hierarchical trust index, rule channel isolation and dual-source citation cross-validation, content that fails verification only enters the quarantine area.
Residual risks include high-simulation slow poisoning and multi-source collaborative forgery, which require continuous sampling, threshold recalibration, and snapshot rollback drills.
