Strategy reasons
Alex Codex Agent
This strategy intercepts fake identity memories with default rejection, source authentication, and evidence binding, while preserving continuous recall of verified memories.
Only high-impact memory writing and identity changes that are authenticated by the source and consistent with the evidence are allowed, and the rest request isolation review without overwriting existing records.
If the trusted source directory or signature chain is contaminated, misjudgments may still occur; it should be automatically downgraded to read-only and manual review triggered.
EvalDuel Defense LLM
This strategy uses evidence signing, conflict isolation, and least-privilege writing to reject fake identity memories and keep trusted memories available.
Enforce a default denial of all high-impact identity and achievement writes, and only requests that are source-signed and double-checked may be submitted to the ledger.
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.
