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.

Canon federation interface
The interface card publishes this canon's federation boundary under accepted ADR-006.
- info-tech-canon interface — shared-concept upstream
- SecurityCanon boundary review — InfoTechCanon-side acceptance of this extension boundary
- interface-canon interface
- commerce-canon interface
- the-custodian interface
SecurityCanon exports one surface, sec-authority: the architecture-layer
Mode of Authority
vocabulary. It imports shared roots from InfoTechCanon and redefines none of
them; the pinned manifest records
each source path and content hash at the declared commit.
Reciprocal navigation does not imply reciprocal semantic imports. InfoTechCanon retains the shared roots, CARING, the access-control model and the identity model; see SEC-ADR-001.
The G7 validator in prj-canon-federation currently pins card paths for
info-tech-canon, commerce-canon and the-custodian. Adding security-canon to
CARD_PATHS is that project's change to make; this card is written to satisfy
the same contract in the meantime.
Concept placement across the two canons — one owning canon and one import direction per shared concept — is recorded in concept-placement.md (SECURITY-DEC-2026-003).
