----------------------------------------

             Summary: camel-langchain4j-agent: expose Result.sources() and 
Result.toolExecutions() as message headers
                 Key: CAMEL-23951
                 URL: https://issues.apache.org/jira/browse/CAMEL-23951
             Project: Camel
          Issue Type: Improvement
          Components: camel-langchain4j-agent
            Reporter: Federico Mariani


The agent producer maps {{Result.content()}}, {{finishReason()}} and token 
usage to headers (CAMEL-23860 pattern), but drops:

* {{Result.sources()}} — the RAG content that grounded the answer (provenance);
* {{Result.toolExecutions()}} — which tools were invoked with which 
arguments/results.

Both are valuable for observability, auditing and downstream routing decisions.

*Proposal*: new headers {{CamelLangChain4jAgentSources}} and 
{{CamelLangChain4jAgentToolExecutions}} in 
{{org.apache.camel.component.langchain4j.agent.api.Headers}}, populated in 
{{LangChain4jAgentProducer.populateTokenUsageHeaders}} (or a renamed 
equivalent).

_This issue was drafted by Claude Code on behalf of Federico Mariani._
