Was I charged for a failed run?
No. A credit is recorded only when a completed Workflow Map is written to your account. If planning fails, nothing is charged. If a run is interrupted, nothing is charged.
The same holds when adding a service. If every new workflow fails to generate, no credit is spent.
The status bar makes the same commitment during every run: an interrupted run is never charged.
