12. Operator Model

Everything executable in KAL is modeled as an operator.

KAL uses a three-way operator classification:

Operator
├── Composite Operator
├── Data Operator
└── Action Operator

12.1 Composite Operators

Composite operators compose, expand, or control workflow structure.

Core composite operators in the current draft include:

core.use
core.splice
core.each

Composite operators do not directly represent target-side actions. Instead, they affect how components are connected, expanded, or controlled.

12.2 Data Operators

Data operators transform, assign, load, or move scoped data.

Core data operators in the current draft include:

core.assign
core.load_vars

Data operators usually operate on controller-side data and interact with KAL scopes.

12.3 Action Operators

Action operators perform external actions against a target, controller, or external system.

KAL core defines the category and common contract shape, but does not define concrete standard-library or platform-specific action operators in this specification.

Concrete non-core operator behavior belongs to host, standard-library, or extension specifications.
