  Entity-Attribute-Value (EAV) knowledge graph. Object definitions are the
  schema (node types), records are the entities (nodes), and relationships are
  typed edges. Tasks, notes, and timeline events attach to records.
entities:
- name: Object
  description: Entity definition / schema for a node type (e.g. Person, Company, Incident, Vendor, Contract)
  identifier: slug
  attribute_types: [text, number, email, phone, url, date, boolean, currency, location, select, social_profile, domain, full_name]
- name: Attribute
  description: A typed field on an object definition
  belongs_to: Object
- name: Record
  description: An instance of an object definition — an actual entity in the graph
  identifier: id
  belongs_to: Object (via object_id / type)
- name: Relationship
  description: Typed edge between two object types (definition) and between two records (instance)
  cardinalities: [one_to_one, one_to_many, many_to_many]
- name: List
  description: A working set of records scoped to one object type
  belongs_to: Object
- name: Task
  description: Actionable item associated with a record (priorities low/medium/high/urgent, due dates, soft-delete on archive)
  belongs_to: Record
- name: Note
  description: Free-form text associated with a record (soft-delete on archive)
  belongs_to: Record
- name: TimelineEvent
  description: Chronological activity entry for a record (task/note/attribute-change/relationship events)
