An abstraction-layer is a design construct that groups related functionality or complexity behind a simplified interface, enabling downstream consumers to interact at a higher level without managing underlying details. Its parameters are: (1) an interface that exposes a subset of capabilities, (2) an implementation that hides the complexity beneath, and (3) a boundary that enforces information hiding. It persists through documentation, implementation conventions, and institutional knowledge in engineering and computing teams.

Definition
Why it is in scope
A human-made conceptual structure that organizes complexity by grouping related functionality behind a simplified interface. It is a deliberate design pattern used in computing, engineering, and cognitive modeling to manage information hiding and reduce cognitive load for downstream consumers.

abstraction-layer IS a specific kind of abstraction — it is a deliberate grouping of complexity behind a simplified interface. A competent speaker calls it 'an abstraction' used in engineering and computing. Direction: specific→general. This is the nearest kind since abstraction-layer is a concrete instantiation of the general concept of abstraction.

An abstraction-layer exists for the sake of simplification: its designed purpose is to reduce complexity by hiding implementation details behind a simpler interface. Servant→master: abstraction-layer serves simplification.

Design patterns ARE built for the sake of abstraction-layer — they encapsulate recurring solutions behind clean interfaces so callers don't need to manage the underlying complexity. Servant→master per Law 8d.

Middleware is a specific kind of abstraction layer: it sits between applications and infrastructure, hiding implementation details behind standardized interfaces. Per Law 9: 'middleware is a type of abstraction layer' passes the competent-speaker test. Per Law 9a: middleware is not an abstraction layer's property or discipline — it is a concrete instantiation of the abstraction-layer concept, specialized for inter-application communication.
