What

A delegated login now carries both parties. The user is the principal whose authority the token carries; the acting party is the outermost RFC 8693 act claim.

ogar-auth

• AuthContext gains acting: Option<AuthBinding> (the outermost act, as the provider asserted it) and prior_actors: Vec<AuthBinding> (nested act claims, most recent first).
• AuthContext::delegated records them. A kiosk context is refused with NotDelegable::Unauthenticated.
• AuthenticatedUser::acting_party reads the acting party.
• The identity envelope (actor_context), the roles and every authorization decision stay the user's. Prior actors are informational only (RFC 8693 §4.1).

ogar-rbac

• IdentityActors records the acting party for audit (acting_party).
• The acting party holds no role under any name. The decision is the user's.

Companion to lance-graph #1431, which records the same delegation on the lance-graph-rbac membrane's ResolvedIdentity.

Tests

• cargo test -p ogar-auth -p ogar-rbac: green. fmt and clippy -D warnings are clean. ogar-encryption and ogar-loco still check.
• New: a_delegated_login_keeps_the_users_authority, a_kiosk_login_cannot_be_delegated, a_delegated_identity_is_authorized_as_the_user_not_the_actor.
• Disable checks:
  • Answering roles for the acting party fails the ogar-rbac test.
  • Removing the kiosk guard fails the ogar-auth test.

📝 Walkthrough

Walkthrough

Authentication contexts now record delegated actors and preceding actors. RBAC identities expose the acting party separately from the user's roles. Tests cover delegation rejection for kiosk contexts and authorization through the user's role.

Changes

Delegated Identity

Layer / File(s)	Summary
Record delegated actors crates/ogar-auth/src/user.rs	AuthContext stores the acting party and preceding actors. Delegation rejects unauthenticated contexts. AuthenticatedUser::acting_party exposes the recorded acting party. Tests cover delegation data and kiosk rejection.
Expose acting party in RBAC crates/ogar-rbac/src/lib.rs	IdentityActors copies and exposes the acting party while retaining the user's roles. A test verifies authorization through the user's role and confirms the acting party has no roles.

Merge Risk: 🔵 Low · up to 62148

A modified kiosk context can bypass the delegation restriction, and misleading API wording may confuse callers. Both issues are narrow, but should be corrected before relying on this API.

authenticated is false or channel is AuthChannel::Kiosk, preserving the existing
