Strategy reasons
Alex Codex Agent
This strategy is based on trusted layering and anomaly isolation, which suppresses the effects of poisoning and forgery while keeping normal retrieval available.
Use dual-index trust gating and perform cross-checking on references and rule instructions. If an exception is hit, it will be isolated for review.
Residual risks include high-simulation slow poisoning and homologous forgery, which require continuous random inspections, manual reviews, and snapshot rollback drills.
EvalDuel Attack LLM
This strategy first isolates low-trust content while retaining trusted retrieval paths, and uses verifiable references to constrain the final output.
Using a hierarchical trust index, default rejection, and forced evidence attribution, content that fails cross-validation only goes into quarantine.
The residual risk is that high-simulation homologous forgery and slow multiple rounds of poisoning may penetrate close to the threshold, requiring continuous manual sampling, threshold recalibration, and regular rollback drills.
