README records the real starting state rather than an aspirational one: the
camera module is NOT detected. rpicam-hello reports no cameras and dmesg has no
sensor probe lines at all, while camera_auto_detect=1 is already set and the
libcamera userland is fully installed. Silence in dmesg is the diagnostic — a
sensor that is seen but misconfigured still probes — so this is cabling, not
config, and the doc says so instead of sending anyone to edit dtoverlay lines.
Also records the trap that /dev/video* nodes already exist on this Pi and belong
to the codec and ISP blocks, so they are not evidence of a camera.
AGENTS.md gives Codex the project-specific rules: it runs ON the target, so it
should test rather than reason about whether something would run; it must not
try to fix the camera in software; and claims about the stream need a command
that ran, because a 200 with no frames looks exactly like a working one.
