/02 About

Identity and access engineering reference for identity delegation and impersonation boundaries, including policy, logical interfaces, recovery and assurance.

Purpose: Identity delegation and impersonation boundaries. Domain: Identity and access. Family: decision. Scenario trigger: Delegate narrowly scoped principal authority. Input assurance: Delegator identity, agent identity and signed delegation chain. Evaluation: Evaluate delegation depth, target scope and consent. Governing policy: Delegation depth audience lifetime and non-escalation policy. Resource-side obligation: Constrain delegated action to original authority. Protected concern: Delegated service execution. Logical interface: Delegator delegatee audience scopes expiry approval and chain. Evidence: Delegation chain authorization and impersonation events. Failure: Forged delegation or privilege amplification. Required recovery: Reject delegation and revoke derived grants. Architectural invariant: Delegation cannot create rights exceeding the accountable principal Adoption: replace reference roles with concrete owner-controlled services. Specify exact provider/consumer identities, schema fields and classifications, signal provenance and freshness, idempotency, authorization lifetime, timeout/retry limits, observation and tamper evidence. A denied or failed operation must not silently become a permitted one. Scope: original vendor-neutral, implementation-agnostic technical reference model. Illustrative logical components and behaviors are neither a deployed system nor evidence of regulatory compliance. Package identities remain stable within the package; cross-package semantic reconciliation requires separate explicit registry support.
