# Framework Leakage

> A defect in which framework or infrastructure types, annotations or lifecycles enter core domain logic, so business rules depend on technical specifics.

Record: `architecture:framework-leakage`
Kind: anti-pattern
Layer: [Enforcement Core](https://banes-lab.com/records/layer/enforcement-core.md)
Severity: discouraged
Scope: domain_boundary
Aliases: Infrastructure-Centric Design
Canonical: https://banes-lab.com/ontology#architecture-framework-leakage

Listed in [Architecture principles](https://banes-lab.com/api/records/architecture.md), after [Utility Dump](https://banes-lab.com/records/architecture/utility-dump.md) and before [Vendor Lock-In Leakage](https://banes-lab.com/records/architecture/vendor-lock-in-leakage.md).

## Repair

- Refactored by: add_adapter, map_to_domain_model, introduce_port, move_framework_outward
- Detected by: request_object_in_domain, ORM_entity_as_domain, framework_annotation_in_core, container_lookup_in_business_logic
- Violated by: Let framework classes, decorators, lifecycle assumptions, request objects, ORM entities, or infrastructure annotations enter core domain logic.
- Measured by: framework imports in core modules
- Enforced by: import rules that keep framework packages out of the core
