Zero Trust Engineering — Subject-attribute provenance and trust

/02 About

Identity and access engineering reference for subject-attribute provenance and trust, including policy, logical interfaces, recovery and assurance.

Purpose: Subject-attribute provenance and trust. Domain: Identity and access. Family: assurance. Scenario trigger: Collect subject authorization attributes. Input assurance: Authoritative claim issuer, update time and integrity evidence. Evaluation: Assess attribute authenticity, conflict and freshness. Governing policy: Subject attribute trust and precedence policy. Resource-side obligation: Publish validated attributes to decision authority. Protected concern: Subject authorization context. Logical interface: Attribute claim issuer timestamp provenance confidence and binding. Evidence: Attribute provenance conflict and acceptance evidence. Failure: Conflicting claims or unverifiable subject attribute. Required recovery: Discard unsupported attribute and request authoritative refresh. Architectural invariant: Unverified attributes must not determine access decisions 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.
