 "symptom": "A Heltec V4 mesh node carries the tag esp32-s3 alongside its own board tags. The reset script's case statement had branches for RP2040/RP2350 and SAMD21 and an ESP32 default, so the mesh node fell through to the default and would have been erased with esptool \u2014 destroying the MeshCore install, the node's identity keys and its contact list, with no backup and no warning.",
