The round-trip test checked h, k, l, I and the two predicted coordinates. The
other ten fields were written and read back unasserted, which is how the
offline --scale path came to lose image_number without a test noticing - it is
the field 3D-integrated reflections carry a fractional value in, and rocking
events cannot be grouped without it.
Reflections are now built by a helper that puts a distinct value in every
field that is meant to survive, keyed on the image and the reflection index so
a value read back from the wrong place cannot match, and checked by one that
asserts all of them. Verified by reintroducing the image_number loss, which
fails six assertions and passes none of them silently.
dist_ewald, observed and on_ice_ring are deliberately excluded and the test
says why: the first two are prediction/integration scratch that is never
written, and the third is recomputed from the resolution by whoever scales.
