Risk boundary
- Keep Core 300, Core 300-P, Core 300S, and Core P350 model language separated unless the evidence supports grouping.
- Do not assign a part code to a filter variant unless the official source exposes that code.
- Marketplace pack-count, media, or low-price claims do not prove official compatibility.
