Generalise the CARING section 32 role set (R-2, INFO-DEC-2026-001)
The role set — Principal, effective actor, Delegator, tool or agent, policy
ceiling, execution context, audit identity — now applies wherever a subject's
access is exercised through another party, rather than to non-human subjects
only.

The gap this closes is not about agents. A support operator impersonating a
customer involves no non-human subject anywhere in the path, yet without the
decomposition that operator's audit identity and policy ceiling collapse into
the customer's, which is the outcome CARING's exposure analysis exists to
prevent. CARING already names customer impersonation as an exposure mode and
ImpersonationBlocked as a control; the vocabulary for analysing it was gated to
subjects the case does not involve. Section 33 was already subject-agnostic, so
the canon applied the execution paths to any subject while restricting the roles
along those paths to non-human ones — an artifact of the section heading, not a
considered position.

Accepted narrowly. Section 32.1 stays agent-stated, with a note on reading the
capability ceiling for a human effective actor. No role is removed, renamed or
added, and section 33 is untouched. Option C, a twelfth dimension, is rejected as
duplicating sections 32 and 33 while touching a dimension set the Kubernetes RBAC
benchmark depends on.

Canon version moves to 0.4.0-RC2-itc2; source version stays 0.4.0-RC2, since
this revises the InfoTechCanon-aligned standard and claims nothing about
upstream CARING. The change is additive: an implementation that applied the set
only to non-human subjects stays conformant for those subjects.

Review record in history/; the SecurityCanon boundary file and placement record
are updated to show R-2 resolved.

Canon federation interface

The interface card publishes this canon's federation boundary under accepted ADR-006.

Each export names its source document and current maturity. Imports identify actual dependencies; reciprocal navigation does not imply reciprocal semantic imports. Custodian supplies ecosystem governance, InfoTechCanon information- processing semantics, and CommerceCanon commercial semantics. Family remains seeded, not authored. The card scope is this federation, not every repo artifact.
