Cancelled workflows are recorded as Failed in duroxide.executions status

[pinodeca]

Summary

Cancelled workflows can be recorded as Failed in duroxide.executions.status, making cancellations indistinguishable from real failures when querying execution rows.

Expected behavior

Cancelled executions should have a distinct terminal status, such as Cancelled, so queries and dashboards can separate user-requested cancellation from failures.

At minimum, the status vocabulary exposed through df.status() and duroxide.executions.status should agree on terminal states, even if casing differs.

Actual behavior

After cancelling a workflow:

• df.status(instance_id) can report cancelled.
• History events show cancellation details.
• duroxide.executions.status records the execution as Failed.

Repro shape

1. Start a long-running workflow.
2. Cancel it with df.cancel(instance_id, reason).
3. Query df.status(instance_id).
4. Query duroxide.executions.status for the same instance.
5. Observe that the durable function status and execution status disagree on whether the terminal state is cancellation or failure.

Impact

Failure dashboards overcount real failures, retry logic can treat user cancellations as retryable failures, and consumers must inspect history payloads to identify cancellations.
