Records one owning canon and one import direction per concept that appears in both layers, as SECURITY-DEC-2026-003. Ten InfoTechCanon concepts are declared imports and the list is closed at what imports.json pins: anything further must be added there with a blob hash before use. Nine concepts are SecurityCanon's own. CARING's Canonical Role, Plane, Condition, Capability and Audit Plane stay upstream with no SecurityCanon counterpart. Both remaining migration candidates stay in InfoTechCanon. The security model is a posture model of the shared spine with eleven upstream imports and nothing to gain from the move; the DevSecOps model is delivery vocabulary that is only incidentally security-flavoured and belongs beside the repository-layout standard and the evidence model. No artifact migrates, consistent with the cancelled T05. The open boundary questions are answered rather than assumed: the identity model is a shared root and SecurityCanon imports PrincipalType only; the small-saas policy, control, evidence and incident artifacts stay whole, with any SecurityCanon example referencing them by id across the federation interface. Two residuals stay open and are InfoTechCanon-internal: CARING Scope against ITC-ACCESS Scope, where ITC-ACCESS is named owner, and the unaccepted CARING section 32 generalisation. This is an agent decision, not human sign-off, and it records no consumer adoption or conformance claim.
