Asking for a field that doesn't exist at all (`filter[is_retracted]=true`, guessing at a name) is also `400` but with a **different message shape**: `"detail":"'is_retracted' is not a valid field for this endpoint."` — one quotes the value in the sentence ("Value 'x' is..."), the other quotes the field name ("'x' is..."); both are JSON:API error objects with `source.parameter: "filter"` and no machine-distinguishable code separating "real field, not filterable" from "not a field at all". An agent handling both cases the same way (both are plain `400`s) will not learn which retry strategy applies — dropping the filter helps case one, trying a different name helps case two, and the response alone doesn't say which. **Practical consequence for this corpus's domain:** OSF has no supported way to list only withdrawn registrations by query; you must either already have a specific id or page through everything and check `attributes.withdrawn` yourself.
