x-note: >-
  Non-destructive enhancements over Databook's published OpenAPI. Captures the API Evangelist
  profile linkage, and the two content gaps found in the harvested spec: no global `security`
  block (the HTTPBearer scheme is declared but never applied at document level), and header
  parameters the reference calls required that the spec declares optional. Nothing here is
  applied to the harvested document.

  update:
    x-apievangelist-observations:
      security_block_missing: >-
        components.securitySchemes.HTTPBearer is declared but no document-level or
        operation-level `security` requirement references it, so a generated client will not
        send Authorization by default even though every operation requires it.
      identity_headers_optional: >-
        databook-user-id and databook-tenant-id are documented as required on every call but
        declared required:false on all 8 operations.
      no_operation_examples: >-
        No request or response examples are present on any operation.
      no_rfc9457: >-
        Errors use a custom error{type,message} envelope rather than application/problem+json.
      no_pagination: >-
        List operations return unbounded result arrays with no paging parameters.
- target: $.tags
  update:
    x-apievangelist-note: >-
      The insights-catalog tag carries a 66-row markdown catalogue of insight ids in its
      description — machine-relevant data published as prose. Captured as data in
      data-model/databook-data-model.yml.
