Zero Trust Engineering — Application availability under control-plane failure

/02 About

Applications and workloads engineering reference for application availability under control-plane failure, including policy, logical interfaces, recovery and assurance.

Purpose: Application availability under control-plane failure. Domain: Applications and workloads. Family: resilience. Scenario trigger: Detect policy or identity control-plane interruption. Input assurance: Local policy freshness, authenticated sessions and business criticality. Evaluation: Evaluate bounded continuation and revocation risk. Governing policy: Application fail-secure and emergency service continuity policy. Resource-side obligation: Restrict risky operations and honor eligible short-lived grants. Protected concern: Critical business application runtime. Logical interface: Control-plane health grant expiry fail mode and recovery event. Evidence: Degraded authorization decision and reconciliation evidence. Failure: Unavailable evaluator, stale cache or enforcement drift. Required recovery: Terminate unsupported sessions and restore consistent authority. Architectural invariant: Control-plane outages must never silently relax application protection 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.
