----------------------------------------
Summary: 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
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._
