fix(flare-workflow): researcher example uses error_mode=skip on fan-out sweeps - #526
Conversation
…ut sweeps A fan-out step's terminal failure only fails the whole workflow when it lands in the engine's failed set; error_mode=retry's exhaustion does that even though every downstream step still runs fine on the partial output (are_dependencies_satisfied treats a skipped dependency the same as a completed one). Confirmed live: a single sweep timing out failed the entire run despite fact-check/follow-up/report all completing on the partial source set. error_mode=skip converts the same terminal failure into a Skip instead, so one slow/flaky source degrades the report gracefully rather than failing the whole run.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Add a failure-path regression test for the fan-out modes.
mock_send always returns Ok, so this test never exercises a terminal fan-out failure. It would also pass if these steps reverted to error_mode: "retry". Add a failing fan-out invocation and assert that the workflow remains WorkflowStatus::Completed, downstream collection and reporting run, and successful results remain available.
