> camel-langchain4j-agent-api: LanguageGuardrail minLanguageRatio option is
> never applied
> ---------------------------------------------------------------------------------------
>
> Key: CAMEL-24608
> URL: https://issues.apache.org/jira/browse/CAMEL-24608
> Project: Camel
> Issue Type: Bug
> Components: camel-langchain4j-agent
> Reporter: Andrea Cosentino
> Assignee: Andrea Cosentino
> Priority: Major
> Fix For: 4.23.0
>
>
> LanguageGuardrail declares minLanguageRatio, sets it from the constructor and
> the public builder method minLanguageRatio(double), and stores it on the
> instance, but validate() never reads it (and there is no getter). A user who
> builds
> LanguageGuardrail.builder().allowedLanguages(ENGLISH).minLanguageRatio(0.8)
> expects at least 80% of the characters to be in an allowed language; the
> ratio is silently ignored, so text that is mostly a foreign script with a
> single allowed-language character still passes. The advertised option does
> nothing.
> Fix: enforce the ratio in validate() (compute the allowed-language character
> fraction and fail when it is below minLanguageRatio), or remove the option.
> _Reported by an automated functional audit._
