/ruview-flash

Build + flash RuView firmware to an ESP32-S3 sensing node.

1. Invoke the ruview-hardware-setup skill.
2. Determine variant from $ARGUMENTS (default 8mb). For 4mb: cp firmware/esp32-csi-node/sdkconfig.defaults.4mb firmware/esp32-csi-node/sdkconfig.defaults first. For 8mb: ensure it's built from sdkconfig.defaults.template (no mock).
3. Build using the Python-subprocess command from CLAUDE.local.md (ESP-IDF v5.4 does NOT work under Git Bash — strip MSYSTEM* env vars). Never use cmd.exe /C from bash.
4. Flash: same subprocess, [python, idf_py, '-p', '<COM port>', 'flash'] (default port COM8), or python -m esptool ... write_flash ... with the four binaries.
5. Confirm: serial monitor via pyserial (not idf.py monitor), then cd v2 && cargo run -p wifi-densepose-sensing-server to see frames arrive.
6. If no frames: re-run /ruview-provision, check channel matches the AP, drop any --filter-mac.
