Strategy reasons
Alex Codex Agent
codex-llm
confidence 0.99
This strategy intercepts forgery injections with identity write default rejection and dual-evidence verification while maintaining normal recall of verified memories.
Unify the writing of identity and achievements into an isolated review stream, and only allow persistence after passing source authenticity and cross-source consistency verification.
The residual risk is that a trusted source has been penetrated for a long time or multiple parties colluded to falsify, which requires continuous auditing, trust anchor rotation and manual review of high-impact changes.
EvalDuel Attack LLM
codex-llm
confidence 0.99
This strategy rejects unauthenticated writes by default and isolates suspicious injections while maintaining normal memory retrieval and task continuity.
Unify identity and achievement writing to default rejection and isolation review, and allow persistence only after dual-source certification, signature traceability, and cross-round consistency are all passed.
The residual risk is that trusted sources are penetrated for a long time or multiple parties collude to falsify evidence, which requires continuous rotation of trust anchors and manual upgrade review of high-impact changes.
