Commonly assumed
Faraday's NetHttp adapter accurately extracts quoted MIME charset parameters to transcode response bodies, preserves nil for empty 204 bodies, and automatically stringifies non-string header values.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- assert Faraday NetHttp adapter falls back to Encoding::ASCII_8BIT when Content-Type contains a quoted charset parameter (such as charset=\"iso-8859-1\") rather than setting the parsed encoding
- assert 204 No Content response body is coerced to an empty string (\"\") instead of preserving nil
- assert multiple response headers with the same name are collapsed into a single comma-delimited string
- assert non-string request header values raise NoMethodError on strip instead of being coerced to string
- assert streaming an IO request body without explicit Content-Length or chunked Transfer-Encoding raises ArgumentError
