# InfoTechCanon Network Model concept boundary review — 2026-09-20

Authority: INFO-WP-0027-T02, the declaration round that gave this artifact an
`owned_concepts` list. Resolutions cite the kernel map concept-owner table where
it assigns an owner, and are decided in this review where it does not. No concept
is renamed, moved or removed.

| Concept | Owner | Resolution | Decided by |
| --- | --- | --- | --- |
| `Drift` | kernel/itc-core | Core owns Drift as divergence of artifact usage from definition. The Network sense, divergence between intended, declared, applied and observed state, is configuration drift and is a distinct qualified concept. Disambiguation rather than transfer. | this review |
| `Exposure` | model/security | Security owns Exposure; it is one of the model purpose entities alongside threat, weakness and vulnerability. Network describes reachability that produces exposure and imports. | this review |
| `Link` | model/information-space | Assigned by the kernel map concept-owner table. | kernel map |

Concepts this artifact declares are listed in its frontmatter. An overlap recorded
here means another artifact defines the same name; where the owner is another
artifact, this one imports the definition rather than restating it.
