/// <summary>
///     Repro for an unfiled bug found during issue triage: the /yaml editor's
///     YamlFileComponent carries its own copy of the kind discriminator map
///     (YamlFileComponent.razor:212-224), and `Other` was never added to it —
///     the fourth hand-maintained kind registry to drift. Saving any config
///     that contains a `kind: Other` resource through the /yaml page fails
///     validation, even though the loader, importer, CLI and MCP all accept
///     it. This test fails on staging until the map (ideally all four
///     registries) is unified.
