    no tags[] array at all, so nothing is overwritten.

- target: $.components.securitySchemes.bearerAuth
  description: Document how the bearer JWT is actually obtained. The published scheme states only http/bearer/JWT
    and omits the OAuth2 client-credentials exchange that mints it.
  update:
    description: JWT bearer token. Obtain interactively from https://canopy.umbra.space/account (24h lifetime) or
      via the OAuth2 client-credentials exchange at https://auth.canopy.umbra.space/oauth/token with audience https://api.canopy.umbra.space
      (or https://api.canopy.prod.umbra-sandbox.space for the sandbox). Token exchange is limited to 50 per rolling
      24h per client.

  description: Flag the undeclared error responses so downstream consumers know the contract is incomplete rather
    than the API being 401-free.
  update:
    x-apievangelist-undeclared-responses:
    - 401 Unauthorized is undeclared on every operation despite bearerAuth being required on all of them
    - 429 Too Many Requests is undeclared despite documented per-endpoint rate limits (see rate-limits/umbra-rate-limits.yml)
    - no 5xx response is declared anywhere in this document
