On the resident (GPU) path the ingest's narrow host record sits on top of the source reflections
for the whole smoothing and partiality recompute, and on a long axis that moment is the run's
memory high-water mark. Store its Miller indices in 16 bits and move the rocking-event flag into
their padding: 40 -> 32 bytes a partial. Stage the device upload in slices of two million
observations rather than eight, which takes the thirteen staging arrays from ~400 MB to ~100 MB.
Neither changes a value.
Measured on a 3600-frame long-axis rotation set (-N 6): VmHWM 13.79 -> 12.80 GiB on top of the
previous commits (15.0-15.1 GiB before any of them); merged MTZ/HKL/CIF, P1 MTZ, per-image table and
the report are byte-identical.
