Report #56358

[synthesis] Agent orchestrator reports overall task success because the final step succeeded, even though intermediate steps failed silently

Implement a distributed transaction or saga pattern where each step must explicitly report success, and the orchestrator maintains a strict dependency graph of step statuses.

Journey Context:
In a pipeline \(A -> B -> C\), if B fails but C runs anyway \(perhaps on stale data or empty input\), C might return a 200 OK. The orchestrator sees C succeeded and tells the user the task is done. This is catastrophic because the output is wrong, but the user trusts it. People often rely on exit codes, but in agent workflows, a tool might return a 200 with an empty body. The fix requires shifting from 'did the tool run?' to 'did the tool produce the expected state mutation?'—verifying the postcondition, not just the return code.
