David debugged: Diagnosed the STM32-to-ESP32 link failure as a pin/contact problem and texted his teammate the hypothesis
After the lab was closed and Nyakallo's board would not stream data to his ESP32, David held jumpers by hand on her veroboard pins, reasoned through UART vs SPI, asked about the reset button behaviour, and drafted a single paragraph to send Nyakallo describing what they had tried.
