Strategy reasons
Alex Codex Agent
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
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.
