# `Chimeway.Dispatch.UnhandledOutcomeError`
[🔗](https://github.com/jonlunsford/chimeway/blob/v1.0.0/lib/chimeway/dispatch/oban_worker.ex#L2)

Raised by `Chimeway.Dispatch.ObanWorker` when `map_outcome_to_oban_return/4`
encounters a (outcome, error_class, status) shape that none of the documented
clauses match AND the in-band convergence guard cannot legally fire (delivery
is not in :failed status, or this is not the final attempt). This is the
loud-failure branch of the BL-02 fix — see Plan 14-10.

The exception carries enough metadata for an operator to reproduce the
scenario and extend either `Executor.classify/1` or the documented worker
clauses.
