Report #7658

[architecture] Agents blindly passing control without signaling certainty, causing error cascades

Include a structured status enum \(e.g., success, needs\_review, failed\) in the handoff payload; if failed, route back to the orchestrator or a fallback agent.

Journey Context:
In sequential pipelines, Agent A might hallucinate an answer and pass it to B, who assumes it is ground truth. Developers try forcing LLMs to output 0-1 confidence floats, but LLMs are poorly calibrated for this. Structured status enums are highly reliable and allow the orchestrator to catch failures early. Tradeoff: Adds a few tokens per turn, but acts as a vital circuit breaker.
