Kind: anti-pattern

Layer: Enforcement Core

Aliases: Shared Model Coupling

Record: architecture:vendor-lock-in-leakage

Severity: discouraged

Scope: modularity, model_governance, domain_boundary

Formed by: Spread vendor-specific APIs, models, exceptions, identifiers, or configuration throughout application and domain code.

Canonical: Ontology

A defect in which an external system's or a vendor's APIs, errors and models spread through application and domain code, so their changes ripple across it.
