- The thermal frame was numbered camera 0 - label RGB, and the colour file of
the same time overwritten - because Vimba counts no camera before open().
The composite now takes each source's configured camera count, and two
enabled cameras may no longer share a label.
- The SDK switches LC_NUMERIC to de_DE when loaded, which made "hotx":0,4336.
Its calls now run under a guard that restores the locale, and the JSON's
numbers no longer go through printf.
- The camera's frame counter is always 0: new frames are told by their time,
so the stream no longer stops after the first one.
- The LUT is empty for the first frame: it is asked again on later ones.
- The SDK is libirbgrab_x86_64-linux.so in the ld cache.
- The null channel traces the CamEvent payload it would have sent.
Tested on tower 111 with the TarisIR mini, the motors mocked: cap_net_raw is
enough, RGB/TIR pairs with one timestamp, the TIR file decodes to the counts
its CamEvent describes, profile switches 0-1-0. 536/536 in the 22.04 container.

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.

Built and tested in an Ubuntu 22.04 container (mock and Vimba+MQTT, 494/494)
and running on tower 111 since 2026-10-14.

A tower's scan grid belongs to that tower, not to the repo: the copy here
had already drifted from the one Staeffelsberg actually uses.
Before the next deploy to Staeffelsberg, move its grid out of the project
folder (scripts/tower-config move) - deploy.sh syncs with --delete and
would otherwise remove the file its config.ini points at.
