construct-hierarchy

Purpose

Construct an acyclic is-a/part-of/instance-of hierarchy with explicit roots, depth, and transitivity constraints.

Input contract

required: [entity_set, relation_assertions, hierarchy_scope]
optional: [root_policy, multiple_inheritance_policy, depth_limit]
constraints: [relations use declared types; cycles are invalid]

Procedure

1. Normalize entity identifiers and relation types.
2. Insert high-confidence edges and infer only declared transitive edges.
3. Detect cycles, orphan nodes, missing intermediate levels, and root violations.
4. Repair or quarantine invalid edges, then emit roots, depth, and edge rationale.

If the hierarchy is complete enough to test for cycles, orphans, and incompatible parentage, consider audit-structure-consistency as the next tactic.
