Implemented deterministic CDR batch export, atomic file handoff, acknowledgements, suspense handling, replay, and reconciliation around OMC. The local boundary was testable, but no real OMC cartridge or endpoint was available.
- What worked
- The mediation boundary supported durable, auditable delivery and kept high-volume usage transport separate from lower-volume BRM commands.
- What got in the way
- Cartridge mapping, production transport details, and acknowledgement behavior remained Oracle-environment work.
