Profile: Self-referencing hierarchy

Models an entity that recursively contains instances of its own type — a corporate ownership structure, an organisational chart, any domain concept naturally shaped like a tree rather than a flat list. Distinct from the fk-scoped-child profile above: a child there belongs to a different parent entity type, whereas here the parent and child are the same type, and the relationship is optional (most rows have no parent at all).

counterparty — a party-like entity that can have a parent counterparty (a self-referencing soft foreign key), rendered as a tree via SQL's has_parent_id hierarchy function and the Qt hierarchy-tree paste seam. Adopting this profile also requires authoring two structural properties this table deliberately omits, because they are not features: :parent_id_column: (the self-referencing FK column name, e.g. parent_counterparty_id) and :hierarchy_name_field: (the display-label column, e.g. full_name) — see Codegen entity meta-model — SQL § "Hierarchy: has_parent_id" for why both are structural, not variability.

One row per feature this profile fixes a value for — any feature not listed here is left to the model's own choice:
