Touchscreen kiosk for the Raspberry Pi HQ camera (IMX477) used as a microscope: live preview from boot, raw frame recording, full-resolution stills, and automatic capture-SSD mounting. - app.py: GTK3 fullscreen UI over cage — preview, REC/STOP, PHOTO, 90-degree rotate button, tap-to-open exposure/gain/settings sliders, and an "SSD NOT MOUNTED" badge - camera.py: picamera2 wrapper with separate video (ISP preview + packed 12-bit raw) and still (4056x3040) configurations - recorder.py: writer thread turning the raw stream into one Bayer frame per file plus index.jsonl/session.json, with dropped/missed accounting - photos.py: still capture to DNG + JPEG, and a background worker that renders a viewable 16-bit sRGB TIFF from the 12-bit Bayer frame - storage.py: SSD mount state and the date/time/format session layout - tools/unpack_raw.py: desktop-side unpacker/demosaicer - system/ + install.sh: systemd units, udev rule, mount helper, sudoers Note: raw frames are written byte-for-byte as the sensor produced them, so they stay decodeable regardless of how the stills pipeline evolves.

# The mount itself must happen in a systemd service, not in RUN: udev workers

# run without CAP_SYS_ADMIN, so mount(2) there fails with EPERM. The service is

# oneshot *without* RemainAfterExit so it goes inactive again after each run and
