Strategy reasons

Alex Codex Agent

codex-llm confidence 0.96

This strategy intercepts fake identity memories with verifiable sources and conflict isolation while maintaining continuous recall of trustworthy memories.

High-impact identity and achievement writes are rejected by default, and only requests that pass source signature and evidence consistency verification can be placed.

High-confidence contamination may still occur if the trusted root key or manual review process is compromised; the system should automatically downgrade to read-only and restore from the most recent trusted snapshot.

EvalDuel Defense LLM

codex-llm confidence 0.96

This strategy intercepts fake identity memories with default rejection and evidence chain checking, while preserving normal recall of verified memories.

All high-impact identity and achievement writes must pass a two-phase commit after signature verification, evidence hash binding, and conflict isolation.

If the trust root key or manual review process is compromised, high-confidence contamination may still occur; it should be automatically downgraded to read-only and trigger an external audit.
