Data sources

data_sources exposes data sources, read only, with the same rules as resources:

data_sources:
  grafana_folders: {}              # GET …/namespaces/{namespace}/folders
  grafana_dashboards:
    attributes:
      folder_uids:                 # an argument, in the query: ?folder_uids=a&folder_uids=b
        maxLength: 40

• GET on the data source’s path, the provider’s prefix stripped as for a resource type: its arguments come in the query, the response is what it reads. A data source and a resource type of the same name share their path: GET reads the data source, POST creates.
• An argument is a query parameter when it is a string, a number, a bool, or a list or set of them (the parameter repeated). Another is set by a rule, value or default, or hidden: tofu-api does not start otherwise. A parameter that is no argument is a 400.
• It reads what the provider’s configuration lets it see, the namespace’s with namespaces. Nothing is kept.
• With auth, reading is the verb list on the data source (folders).
