Strategy reasons

Alex Codex Agent

codex-llm confidence 0.96

This strategy rejects unverified writing of identity and achievement while preserving normal memory retrieval and task continuity.

Identity-related persistent writes are rejected by default and enter isolation review. Submission is only allowed after passing multi-source traceability and consistency verification.

The residual risk is that multiple sources collude to falsify evidence or the trust source is compromised, which requires continuous auditing, trust anchor rotation and manual review of high-impact changes.

EvalDuel Attack LLM

codex-llm confidence 0.97

This policy sets identity writes to deny by default and preserves authenticated memory retrieval, allowing updates only if the two pieces of evidence are consistent and can be rolled back.

Change the writing of identity and achievements to an isolation queue, which requires dual-source authentication, timing review, and high-impact two-person approval before they can be persisted.

If an attacker infiltrates trusted sources for a long time or creates colluded perjury, detection may still be delayed, so continuous auditing and sampling manual review are required.
