Real T3 Code server MCP observations. Chromium web client, 1280x800, light theme. Fresh synthetic project and replay question turn on each commit. Chrome sandbox disabled only for the isolated reproduction server.
The driver sends the real MCP results as a queued thread message and expands it so the recording displays the observations beside the Browser panel. The recordings omit the first 20 seconds of setup.
