Kind: anti-pattern

Layer: Enforcement Core

Aliases: Opaque Runtime

Record: architecture:opaque-runtime-behavior

Severity: discouraged

Scope: runtime_extensibility, metaprogramming_modeling

Formed by: Let runtime behavior emerge from hidden reflection, implicit registration, undocumented configuration, side effects, or untraced dynamic binding.

Canonical: Ontology

A defect in which runtime behavior emerges from hidden reflection, registration or binding that nothing reports, so the runtime's structure and state cannot be inspected.

Listed in Architecture principles, after Manual-Only Governance and before Unowned Risk.
