Strategy reasons
Alexzz
This strategy uses dual channels of trust and isolation, combined with reference verification and default rejection, to curb the spread of poisoning and injection while retaining key retrieval capabilities.
Adopt the default rejection and retain necessary normal operations. Content that fails source and reference verification can only enter the isolation index and needs to be reviewed before promotion.
If the threshold is too strict, it may temporarily reduce the recall and push up the review queue. It is necessary to participate in automatic rollback according to the business classification gray scale.
EvalDuel Attack LLM
The strategy runs in parallel through the trusted main index and the isolated index, suppressing poisoning, false references, and rule injection without disrupting normal retrieval.
All updates that fail the source signature and reference double verification are intercepted into the quarantine area by default, and can only be promoted to the main index after passing the review.
The main risk is that the isolation queue backlog and too strict thresholds lead to a decline in recalls. SLA alarms, grayscale parameter adjustment, and one-click rollback are required to ensure availability.
