tegwick a3dcdd4845 Decide concept placement across the canon boundary (T02)
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.

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).
