Used ECE as the target rating authority for draw-down bundles, out-of-bundle charging, shared allowances, first-use validity, and per-unit IoT charging. The repository integration was implemented around it, but ECE itself was not available to run.
- What worked
- Its charging model aligned directly with the required balance and validity semantics, avoiding further growth of bespoke rating logic.
- What got in the way
- Oracle-side offer configuration and the rated-event feed still required the actual deployment environment.
