// SEP-2322 (Multi Round-Trip Requests / IncompleteResult) conformance scenarios.
// SEP-2322 (Multi Round-Trip Requests / InputRequiredResult) conformance scenarios.
// The csharp-sdk ConformanceServer surfaces the matching tools/prompts via
// ConformanceServer.Tools.IncompleteResultTools and ConformanceServer.Prompts.IncompleteResultPrompts.
// Each scenario uses the conformance harness's RawMcpSession, which negotiates DRAFT-2026-v1
// ConformanceServer.Tools.IncompleteResultTools and ConformanceServer.Prompts.IncompleteResultPrompts
// (the class names predate the conformance-suite rename from "incomplete-result-*" to
// "input-required-result-*"; the wire-level tool names now match the new convention).
// Each scenario uses the conformance harness's RawMcpSession, which negotiates 2026-07-28
// so the csharp-sdk emits InputRequiredResult on the wire. These tests skip until the
// upstream conformance package ships with SEP-2322 scenarios
// (https://github.com/modelcontextprotocol/conformance/pull/188).
// installed conformance package ships SEP-2322 scenarios <em>and</em> emits this SDK's
// draft wire string (see <see cref="NodeHelpers.HasMrtrScenarios"/>).
//
// input-required-result-tampered-state and input-required-result-capability-check are
// implemented by ConformanceServer.Tools.IncompleteResultTools.ToolWithTamperedState
// (HMAC-protected requestState; a tampered requestState surfaces a -32602 JSON-RPC error)
// and ToolWithCapabilityCheck (gates inputRequests on the per-request
// _meta clientCapabilities envelope). Both behaviors also have in-process wire-level
// regression coverage in MrtrProtocolTests so they stay verified even while the published
// conformance package's draft wire string lags this SDK.
