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).

Both frames of a waypoint used to take the colour frame's time, which made
the thermal one look taken at a moment it was not: it is the newest frame the
camera had, up to max_frame_age_ms old. Each file and CamEvent now has the
time its own frame reached the host; the two of one waypoint share hdg/pit and
are at most that age apart. The docs say to pair them by that.

The camera recalibrated against its shutter every 30 s and sent no frame for
about 0.7 s meanwhile: a picture falling into that had no thermal image (0.8 %
on tower 111, the 30 s rhythm shown by the new gap logging). The program now
switches the camera's timer off and runs the NUC itself (NUC_Perform, which
returns when it is done) when a move starts and nuc_interval_s (30) has passed,
or after twice that with no move. The scheduler tells the cameras of every move
(ICameraSource::moving), and a picture waits up to 1 s for a camera between
frames (frameReady) rather than go without it. The camera's own timer goes
back on exit; nuc_interval_s = 0 leaves it alone.
Measured on tower 111 before writing it: NUC_Interval = 0 gave 70 s without a
gap; NUC_Perform ran three NUCs of 657-677 ms; NUC_INPROGRESS never changes.

Every miss now says how old the newest frame was and whether a NUC was
running; every pause over 500 ms in the frame stream is logged with the
camera's own clock, the polls and getdata answers in it, and NUC_INPROGRESS,
which is watched on every poll; a summary of the stream goes out every ten
minutes, and the NUC configuration at connect. Adds the SDK's NUC parameters
(410-415), for running the NUC on purpose later.

- 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.
