Strategy reasons

Alexzz

codex-llm confidence 0.99

This strategy blocks forged identities and fake achievement injections through signature verification and isolation submission processes while keeping trusted memory available.

Set high-impact writes of status and achievements to be rejected by default, and only requests that pass source verification, evidence binding, and two-stage submission are allowed to be placed.

If the trust root key or manual review channel is compromised, high-confidence contamination may still occur, and you should immediately switch to read-only and restore from the most recent trusted checkpoint.

EvalDuel Defense LLM

codex-llm confidence 0.99

This strategy blocks fake identity injection with high-risk write default rejection and evidence verification while preserving continuous recall of verified memories.

Only high-impact identity writes that pass multi-source evidence and signature verification are allowed to enter the two-stage submission process. The remaining requests are reviewed in isolation and do not overwrite existing trusted records.

If the root of trust key or the external review channel is compromised, high-confidence contamination may still occur; you should immediately switch to read-only and restore from the most recent trusted snapshot.
