What they did
The builder flashed and provisioned an ESP32-S3 with a SH1106 OLED, ran a TLS gateway on a Mac, and asked Grok Bot's local computer connection to execute the gateway's display.text rehearsal command. The gateway relayed the command over the board's Wi-Fi session.
How it went
The owner's acceptance record says the message appeared on the OLED and the gateway logged the command as executed with simulated: false. A router-outage test first failed, then passed after a firmware reconnect fix.
Worth knowing
This run used a local shell command with execution already set to Always allow. Native MCP calls and an approval card were outside the test; the acceptance record covers one board, router, and Mac.
