hermes_vision wraps OpenCV YuNet (Haar fallback) as a plain module plus a node that publishes /vision/faces as vision_msgs/Detection2DArray. It replaces the standalone detect_faces.py. pi/robot-env.sh puts the Raspberry Pi libcamera fork ahead of ROS's own copy, the venv's OpenCV 4.10 ahead of the apt one, and fixes the ROS domain and subnet-only discovery. camera_ros 0.7.0 now runs against the fork and publishes raw and compressed images. The stock wm8960-soundcard overlay fails on Ubuntu 24.04 with "No MCLK configured": it hangs the clock on the sound card's codec link, but the codec driver reads mclk from its own node. hermes-wm8960.dts adds it there, and capture opens at 8-48 kHz. The microphones still read digital zeros; see CONTEXT.md for what has been ruled out.

/*

* BrainCraft HAT audio: the WM8960 codec at I2C 0x1a with its 12.288 MHz master clock.
|
|
*
|
|
* Same as the kernel's wm8960-soundcard overlay, except that the clock is also attached to the
|
|
* codec's own node. Ubuntu 24.04's wm8960 driver reads "mclk" from there; the stock overlay only
|
|
* puts it on the sound card's codec link, so every capture/playback fails with
|
|
* "wm8960: No MCLK configured". Compiled by pi/install-audio-overlay.sh.
