  Entity-relationship graph for the AWS Lambda API, derived from OpenAPI schemas
  and id-reference fields (FunctionName/FunctionArn, LayerName, Qualifier).
entities:
  - name: Function
    schema: FunctionConfiguration
    identifiers: [FunctionName, FunctionArn]
    note: The core resource; FunctionArn optionally carries a version/alias qualifier.
  - name: Version
    schema: FunctionConfiguration
    identifiers: [Version]
    note: Immutable numbered snapshot of a function (plus $LATEST).
  - name: Alias
    schema: AliasConfiguration
    identifiers: [AliasArn, Name]
  - name: EventSourceMapping
    schema: EventSourceMappingConfiguration
    identifiers: [UUID]
  - name: Layer
    schema: Layer
