| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Scope | A vendor rating for IP, not a measured part. Edge (shoreline) density counts both directions of the link, as UCIe's own shoreline figures do. |
