Tool approval UI not triggered because data-tool-call-approval parts in unexpected format

Client SDK

I’m using handleChatStream to adapt Mastra streams into the AI SDK v6 message/part format for my frontend.

I noticed an inconsistency specifically around tool approvals: the emitted data-tool-call-approval message part is a DataUIPart but I would expect it to be a ToolUIPart. Location in code. Work around is simple for now, just curious if this and other ai-sdk integration inconstancies are tracked, or if this is desired behavior.

e.g.

          "parts": [
              {
                  "type": "step-start"
              },
              {
                  "type": "tool-myTool",
                  "toolCallId": "tooluse_mtSdZ9yPnPjE17KjVUorP4",
                  "state": "input-available",
                  "input": {
                  }
              },
              {
                  "type": "data-tool-call-approval",
                  "id": "tooluse_mtSdZ9yPnPjE17KjVUorP4",
                  // missing "state" key, expected state: "state": "data-tool-call-approval"
                  "data": {
                      "runId": "a46f93b6-6d7e-47e4-861d-3a60c9516eb8",
                      "toolCallId": "tooluse_mtSdZ9yPnPjE17KjVUorP4",
                      "toolName": "myTool",
                      "args": {
                      },
                      "resumeSchema": ""
                  }
              }
          ]

          "parts": [
              {
                  "type": "step-start"
              },
              {
                  "type": "tool-myTool",
                  "toolCallId": "tooluse_mtSdZ9yPnPjE17KjVUorP4",
                  "state": "input-available",
                  "input": {
                  }
              },
              {
                  "type": "data-tool-call-approval",
                  "id": "tooluse_mtSdZ9yPnPjE17KjVUorP4",
                  // missing "state" key, expected state: "state": "data-tool-call-approval"
