Report #8444

[architecture] Agent A calls Agent B, B fails and returns a natural language apology, which Agent A misinterprets as a successful execution

Separate execution status from payload in inter-agent returns. Use a structured envelope \(e.g., \{status: success\|error, data: ..., error\_message: ...\}\) so the calling agent can deterministically check status before proceeding.

Journey Context:
LLMs are sycophantic and often frame failures politely \('I'm sorry, I couldn't find the file, but I think...'\). Another LLM reading this might interpret the presence of a suggestion as a success. A structured status field allows the calling agent to programmatically branch to error handling without relying on semantic interpretation of the outcome.
