Rietschen's RGB camera switched to 12 bits offers BayerRG12Packed, not
BayerRG12p, and the program took it for an unknown format: from 2026-10-26
11:33 every picture was saved as "legacy", undebayered raw bytes. The two
are not the same format under two names. Both put two pixels in three
bytes, but the GigE Vision 1.x packing carries the first pixel's high bits
in the first byte, where GenICam's 12p carries its low ones; read as 12p
every other pixel is scrambled.
BayerRG12Packed is now a layout of its own, unpacked and sampled for
brightness its own way and de-Bayered like 12p. Checked against the
hardware on rietschen's NIR camera (Mono12Packed, the same packing): the
12-bit frame unpacked this way differs from an 8-bit frame of the same view
by 2.8 on average, unpacked as 12p by 29. The gige recipe prefers
BayerRG12Packed, so a re-export keeps the 12 bits. Tests 544/544 (mock).

A TarisIR mini (driver = taris) is a second camera source behind a
CompositeCameraSource: the colour camera is asked first, then the thermal one
for its newest frame, and both frames carry the colour frame's timestamp.
Counts are saved 16-bit lossless under TIR/, and the CamEvent gains cal,
missed, tmax, tmed, hotx and hoty (docs/mqtt-api.md). The SDK is declared in
IrbgrabApi.h and loaded with dlopen, so no SDK file is in the repository; a
missing or unreachable camera stays offline (Health cams_offline) while the
scan goes on. scripts/fgc-setcap gives the binary cap_net_raw after a build.
Built and tested in an Ubuntu 22.04 container (mock, MQTT, Vimba+MQTT,
534/534), plus a mock run with RGB/TIR pairs. Not yet run against the camera.
