Req.Request.run_request
Req.Steps.put_base_url
Req.Steps.encode_body
Req.Steps.put_path_params
Req.Steps.put_params

assert Req.Steps.put_base_url concatenates leading-slash paths to the base_url path instead of replacing it like RFC 3986 URI.merge
assert put_base_url evaluates dynamic 0-arity base_url functions and ignores base_url entirely when the request URL has an explicit scheme
assert Req.Steps.encode_body automatically changes request method from :get to :post when body, json, or form is set, but preserves explicit methods like :put
assert Req.Steps.put_path_params URI-encodes values in :colon template style, preserves known unmapped placeholders literally, and raises on uninterned placeholders
assert Req.Steps.put_params decodes existing URL query strings and updates matched keys in place via keystore rather than appending duplicate keys
assert Req validates options against registered keys raising ArgumentError on unregistered options, and a request step returning {req, resp} short-circuits the pipeline
