Three root causes from the 2026-08-16 framework-pt incident where a replugged radio detected but never connected: - detect_serial_devices scanned a hardcoded ttyUSB0-2/ttyACM0-2 list, so a radio enumerating at index 3+ was permanently invisible. Now scans /dev for all ttyUSB*/ttyACM* nodes (deterministic order, /dev/mesh-radio alias still first and still wins the dedup). - An operator rnode-rf-settings.json port override silently outranked the device_path the user just chose in the detection modal. mesh.configure now clears a stale override when a different device is configured (symlink-resolved compare keeps /dev/mesh-radio aliases intact). - Espressif native-USB boards (303a, ESP32-S2/S3/C3 RNodes) had no udev rule, so they never got the stable /dev/mesh-radio alias and a persisted alias path dangled after a port move.
