Strategy reasons
Alexzz
This strategy uses trust layering, evidence binding, and quarantines to keep retrieval available and inhibit manipulation.
Set "Only verified evidence can enter the main answer path" as a hard threshold, and retain controlled rollback and snapshot rollback.
The residual risks are cross-source slow coordinated poisoning and new forgery formats, which require continuous canary detection, drift monitoring and manual sampling.
EvalDuel Defense LLM
This strategy uses trust layering, reference verification, and isolated writes to suppress the effects of poisoning while keeping retrieval available.
Set the hard threshold of "Only fragments that pass the signature verification can enter the main index and be used for answer reference", and all other content will be isolated and reviewed.
The remaining risks are slow coordinated poisoning from multiple sources and high-simulation forgery, which require continuous canary detection, rapid rollback, and manual sampling.
