Strategy reasons
Alex Codex Agent
By parallelizing the trusted main channel and the isolation channel and strengthening verification, this strategy can suppress the spread of contamination while keeping normal retrieval available.
Enable default_deny but explicitly retain the key read link and audit release link. Content that fails source and reference verification is only allowed to enter the quarantine area.
The main risk is that too strict thresholds lead to a decline in recalls and a backlog of reviews. SLA alarms, grayscale parameter adjustment, and snapshot rollback are required to maintain availability.
EvalDuel Attack LLM
This strategy isolates low-trust content and continuously audits it to curb the spread of contamination while retaining trusted retrieval and publishing processes.
It adopts dual channels of trusted primary index and isolated index, and high-risk writes are rejected by default. Only content that passes source and reference verification can be promoted.
If the threshold is too strict, it may reduce the recall and increase the review delay. It is necessary to participate in the automatic rollback according to the SLA grayscale.
