The array-parameter fix derived the WQX3-vs-legacy decision a second time at each call site to pick a delimiter, in opposite polarity from the branch that had already picked the URL. Set both together instead, so the "wqx3_url implies repeated params" invariant reads off one branch per arm. _what drops use_wqx3 and its duplicate services_wqx3 membership test for a flat three-way branch; the stack depth to _legacy_only_url is unchanged, so the hand-tuned stacklevel in _warn_wqx3_unavailable still lands. _query_with_retry now builds a new payload rather than writing joined values back into the caller's dict. The legacy path previously mutated the caller's kwargs -- storing None for scalars -- while the new WQX3 path did not, so WQP_Metadata saw different parameters depending on the interface. Live WQX3 checks confirm semicolon lists are wrong for every array parameter tested, not just siteType: huc, organization, providers, siteid, countycode, statecode, sampleMedia, characteristicType, characteristicName, pCode and countrycode all return correct unions only with repeated keys. The tests' "River/Stream" example is a WQX3 Location_Type response value, not a valid siteType filter term -- the live service rejects it -- so the examples now use Stream/Well.
