Unclear Whether this is purely a rename or also changes how discovery-state errors are detected in some edge case is not established by the evidence.

What

Internal code in the MCP (Model Context Protocol) OAuth login flow was reworked: the check for a discovery-state error now looks for a differently-named error type, and several "persist failed" logging calls were renamed to use a different helper. This happened in both the regular and enterprise variants of the MCP OAuth client.

Why

These look like internal renames rather than a behavior change, so there's likely nothing for users to notice here.
