+#### FW Analysis
+
 I found an [IoT FW analysis tool](https://github.com/ericyoc/iot_device_firmware_analysis_poc/tree/main) on GitHub, which I used for generating a quick [report](firmware/bridge/report.txt).
-Interesting findings:
-- Lock state tracking (`GO_TO_STATE_INSTANTOPEN`, `MOTOR_STALL`, ...)
-- Confirmed cloud communication via MQTT and lock communication via BLE
-- Contains embedded RSA and EC Private Key structural markers
-- Implements `secure_boot_v1`
-- Uses `mbedtls` for modern ciphers
-- Exposes path from dev's machine (his name seems to be Pierre, lol) `/home/pierre/bridge/components/button_driver/iot_button.c`
-- Runs FreeRTOS
-- Uses SPIRAM

+##### Reverse Engineer Anything
+
+Using [REA](https://github.com/morluto/rea), we ran the firmware through Claude Code and received a short [report](firmware/bridge/claude_firmware_analysis.md).
