# InfoTechCanon Core 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 |
| --- | --- | --- | --- |
| `Activity` | kernel/itc-core | Core and Information Space state this definition in nearly the same words. Core owns the provenance mechanism; Information Space imports it. | this review |
| `AgentBrief` | kernel/itc-core | Assigned by the kernel map concept-owner table. | kernel map |
| `AgentReference` | kernel/itc-core | Same definition restated. Core owns it as part of the provenance family the kernel map assigns to Core; Information Space imports. | this review |
| `Alias` | kernel/itc-core | Core defines the general alternative identifier or label; Information Space restates it and imports. | this review |
| `DecisionRecord` | kernel/itc-core | Core owns the record type; the Information Space enumeration of context, options, rationale and consequences is guidance on the same concept, not a second definition. | this review |
| `Dependency` | model/task | Assigned by the kernel map concept-owner table. | kernel map |
| `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 |
| `ExternalReference` | kernel/itc-core | Core owns the outward pointer; Information Space scopes it to sources outside the information space and imports. | this review |
| `Identifier` | model/identity | Assigned by the kernel map concept-owner table. | kernel map |
| `Influence` | kernel/itc-core | Identical definitions. Core owns it with the provenance family; Information Space imports. | this review |
| `Label` | kernel/itc-core | Three uses, one owner. Core owns Label as a human-readable name. The Tagging sense, a display-oriented representation of a Tag, is a qualified use of the same word and keeps its section; Information Space imports. No rename. | this review |
| `Namespace` | kernel/itc-core | Core owns the naming scope; Information Space adds the collision-prevention purpose and imports. Identity Realm and Tagging namespaces specialize it rather than redefining it. | this review |
| `Profile` | undecided | Unresolved and deliberately undeclared by Core. Three senses exist: the canon profile artifact (Core prose), the identity Profile owned under accepted CUST-ADR-006, and the Observability runtime performance profile already disambiguated in the identity boundary review. The kernel map assigns Profile to Core, which contradicts the accepted identity ownership. Resolving it needs a decision, not a declaration. | kernel map |
| `ProvenanceRecord` | kernel/itc-core | Assigned by the kernel map concept-owner table. | kernel map |
| `Source` | kernel/itc-core | Identical definitions. Core owns it; Information Space imports. | this review |
| `Standard` | kernel/itc-core | Assigned by the kernel map concept-owner table. | kernel map |
| `VersionRecord` | kernel/itc-core | 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.
