A ladder is a hierarchical classification structure in which entities are organized into successive levels of generality, each level serving as a parent category for the one below. It operates through INSTANCE_OF links: specific items point to their nearest kind, and the chain from leaf to root forms a path of increasing abstraction. The ladder is used in taxonomy, ontology engineering, and knowledge organization to ensure every item can be placed within a broader categorical framework without redundant leaps. Persistence mechanism: encoded in taxonomic databases, ontologies, and classification systems maintained by human institutions.

Definition
Why it is in scope
A human-made hierarchical classification structure in which items are organized into successive levels of generality, each level serving as a parent category for the one below. Built to support taxonomy, knowledge organization, and systematic reasoning by providing a path from specific instances to broad kinds.

A ladder is a hierarchical structure whose designed purpose is to serve classification — organizing entities into ordered categories. For whose sake? The ladder serves classification. Law 8d: servant→master, not dependency.
- cmr98h9fl008khcxfwebiv8rnINSTANCE_OF →
A ladder is a specific kind of tool — an artifact that extends human capacity for reaching elevated positions. INSTANCE_OF per Law 9: a competent speaker calls a ladder 'a tool' (broad sense: artifact extending human capacity). The ladder is a concrete instance of the general category.
