+"""Tests for the MCPServerTask reconnect signal.
+
+When the OAuth layer cannot recover in-place (e.g., external refresh of a
+single-use refresh_token made the SDK's in-memory refresh fail), the tool
+handler signals MCPServerTask to tear down the current MCP session and
+reconnect with fresh credentials. This file exercises the signal plumbing
+in isolation from the full stdio/http transport machinery.
