Entity Types

SPECLAN uses a layered hierarchy of entity types. Features can be nested to create hierarchical sub-feature trees:

Entity	ID Pattern	Purpose
Goal	G-###	Business objectives
Feature	F-####	System capabilities (hierarchical — can contain sub-features)
Requirement	R-####	Testable conditions
Change Request	CR-####	Modifications to locked entities
Template	UUID v4	Reusable structures
