source: https://dynamicfeed.ai/schemas/index.json and the 15 JSON Schema documents it links (saved under json-schema/),
  https://dynamicfeed.ai/receipt-spec, the response envelope observed on POST /v1/batch, and openapi/_original/dynamicfeed-ai-openapi.json
summary: 'The REST contract is schema-less on the response side: all 158 operations declare `{}` for 200 and the
  only component schemas are the signup body and the FastAPI validation error, so no entity graph can be derived
  from the OpenAPI. Dynamic Feed publishes its data model elsewhere — as a family of 14 JSON Schema receipt profiles
  (DF-VERIFY/1) plus the OKF reliability object, and as a uniform response envelope (data + provenance + freshness
  + signature + served_by). That published model is recorded here; nothing was invented to fill the OpenAPI gap.'
