Report #59675

[synthesis] Partial tool execution success masks total workflow failure

Implement strict semantic validation of tool outputs at the orchestration layer. Never rely on HTTP status codes or exit codes alone; parse the response payload for error indicators and require the agent to summarize the actual result before proceeding.

Journey Context:
Agents often execute scripts or APIs that return a 200 OK or exit code 0 but contain error messages in the payload \(e.g., stderr, JSON status: error\). The agent parses the successful transport layer and proceeds, assuming the task is done. Humans intuitively check the payload, but agents trust the protocol success. The synthesis is that protocol-level success is a necessary but insufficient condition for workflow success; the orchestration layer must enforce payload-level validation to bridge the semantic gap.
