Read the evidence, not the green tick.

Test normal, repeated, stopped and failed paths separately. Mark unobserved results unknown rather than passing the whole workflow from one successful message.

Use enrollment and execution history to reconstruct a specific run. A completed action is not automatically a delivered message or a resolved inquiry.

Label each observation accurately. A successful workflow action alone does not establish delivery, human attention, a booking or a sale.

Trace the actual reply channel and matching event before changing the stopping rule. A visible message may not belong to the trigger path you assumed.

Find both sending paths and their initiating events. Duplication may come from repeated calls, multiple workflows or an integration—not just one re-entry setting.

Review the pending action in its actual workflow instance. A staff reply or changed contact field does not automatically prove every queued message was cancelled.

Compare billed units with the actual response path and your stated assumptions. An unexpected charge is a reason to inspect usage, not proof that a message produced revenue.

Before changing a live response path, identify the old sender, pending work and rollback. Do not run two acknowledgements just to make the transition feel safer.

Judge the pilot by a useful, controlled response path and its real cost—not by how many messages were sent or how impressive the workflow looks.
