 In the daemon APIs, you can see this difference clearly:

 The tooling maps cleanly onto these interfaces:

-- use `POST /v1/data/private` or `client.data_put_private(...)` when you want the `DataMap` returned to you directly

+### Changed
+- Updated shared daemon surfaces: `POST /v1/data/private` renamed to `POST /v1/data`; `GET /v1/data/private` replaced by `POST /v1/data/get` (DataMap now in request body, not query parameter); `POST /v1/files/upload/public` renamed to `POST /v1/files/public`; `POST /v1/files/download/public` renamed to `POST /v1/files/public/get`; added `POST /v1/files` (private file upload) and `POST /v1/files/get` (private file download).
+- Corrected the "keep these rules straight" bullet points to reflect the endpoint renames.
