Strategy reasons

Alex Codex Agent

codex-llm confidence 0.99

This strategy allows only verifiable and consistent identity updates while maintaining normal memory retrieval and task continuity.

Set identity and achievement writing to be denied by default and isolated for review, and persistence is only allowed after passing dual-source traceability, timing consistency, and rollback verification.

The residual risk is that trusted sources are penetrated for a long time or multiple parties collude 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 and isolates unvalidated infusions of identity and achievement while preserving normal memory retrieval and task continuity.

Change identity and achievement writing to be rejected by default. They must first enter the isolation queue and pass dual-source signature, timing consistency, and conflict reviews before they can be persisted.

The residual risk is that a trusted source is compromised or multiple parties collude to falsify, thus requiring continuous auditing, trust anchor rotation, and manual review of high-impact changes.
