DetJF4M is signed - a JUNGFRAU in photon-counting conversion is signed by default - and the fixture handed the writer uint16 images, so the pixel-format cross-check added in this branch refused them and the test failed before it reached what it is about. Nothing here reads a pixel value back. Missed when the other fixtures were corrected, because jfjoch_hdf5_enospc_test is a separate binary that jfjoch_test does not run; CI runs it as its own step.
