Overview

Abstract base class for ancestry records. Each dagable model gets a concrete subclass (e.g. Category::Ancestry) backed by {table}_ancestries.

Each row represents a path between a predecessor and successor with a given depth:

• depth 0 — self-referential row (every node has one)

• depth 1 — direct parent-child relationship

• depth N — transitive relationship N edges apart
