Two things, both about telling one ice quantity from another.
The ice score's spot channel had its own band half-width of 0.02 A^-1 while the spot finder marks
ice rings at 0.03 (ice_ring_width_Q_recipA). The 0.02 was justified by a 5 pp specificity gain
measured on the PYTHON PROTOTYPE, which used a fitted beam centre and a mask-derived coverage table;
the shipped port, which takes the geometry's centre and the azimuthal profile's own live pixel
count, does not reproduce it. Measured over the corpus by truth class rather than by directory
label, at 0.02 vs 0.03 on the combined score: ice loops 62.13/62.19%, _icy protein 89.03/89.79%,
_clean protein 16.51/16.31%, water 17.19/20.03%. The widths are indistinguishable except on water,
where one of the four loops is independently known to carry a full hexagonal pattern. So the width
is now a parameter and the pipeline's own value is passed in - one band width, not two. The 0.012
tolerance in the radial channel is NOT a second band width, and is renamed CENTRE_SMEAR_Q to say so:
it is how far either side the channel looks for the bin a mis-set beam centre moved the ring to.
The rest is naming. Three kinds of number were all called score, or built from things called count,
and a reader could not tell from the name whether 1 meant "none" or "certain" - which are opposite.
The convention, now stated in docs/CPU_DATA_ANALYSIS.md: *_score is bounded [0,1] and 1 is
certainty, *_ratio is unbounded and 1 is nothing, *_count is a count. The C++ identifiers for the
ice ring ratio follow it (ice_ring_score -> ice_ring_ratio, GetIceRingScore -> GetIceRingRatio,
PlotType::IceRingScore -> IceRingRatio), and the local in the scaling gate that shadowed the new
ice_score while meaning the ring ratio is renamed with them.
Nothing outside the source moved: the CBOR keys ice_ring_score and ice_ring_score_mean, the datasets
/entry/MX/iceRingScore and iceRingScoreMean, the ice_ring_score plot type and the --ice-min-score
flag are all unchanged, and were checked to be after the rename. Renaming those changes stored
files, the stream format, the REST API and a CLI flag, and is a separate decision.

This is an UNSTABLE release. It includes many experimental features, as well as many AI generated fixes. We recommend using rc.152 for production use.
* **rugnux: significantly better quality of results, and faster.** A large rework of integration, scaling, merging, geometry refinement and space-group determination, together with measurements the program previously made no attempt at - the direct beam before indexing, the beam stop, the goniometer rotation scale, and the stretches of a sweep the crystal did not deliver. A rotation dataset typically gains observations at better <I/sigma> and R_meas, and every `mx` and `scale` run writes a `<prefix>_report.txt` results report modelled on XDS's `CORRECT.LP`. Many defaults moved with it: spot detection is self-calibrating, beam-stop detection and rotation geometry post-refinement are on, resolution limits default to as far as the detector reaches, and ice-ring handling engages only where the crystal is measured to have ice.
* **jfjoch_viewer:** the beam-stop shadow, the detector calibration and the beam-centre measurement are reachable from "Analyze dataset"; the settings panel reports how the sample moved and how polarized the beam was; image rendering and interaction are faster.
* **Performance:** bitshuffle+LZ4 images are decoded on the GPU rather than on the host, with the bitshuffle inverse fused into preprocessing so the decompressed frame is never held in device memory.
* **Broker, writer, packaging and build:** image-slot lifetime and locking fixes, per-image datasets sized by the images actually written, the Debian/Ubuntu broker package renamed to `jfjoch`, and `image_analysis` compiling under MSVC again.
**Breaking change to the rugnux command line:**
* `--azint-only` and `--scale` are **removed**, replaced by `--mode azint` and `--mode scale`; the full pipeline is `--mode mx` and remains the default. A script passing the old flags now fails with the list of valid modes rather than silently running the wrong one.
* `-t`/`--stride` is **refused on rotation data**: skipping frames cuts every reflection's rocking curve, so the combined fulls and their partiality would be measured over frames the sweep never recorded. Select a contiguous range with `-s`/`-e` instead. `--mode azint` and `--force-still` still take a stride.
**Breaking changes to OpenAPI** - regenerate the client (`jfjoch-client` 1.0.0-rc.161, `frontend/src/client`) or read the affected fields as optional:
* `image_scale_b` is removed from the `plot_type` enum, so a client requesting that plot now gets an error rather than a curve.
* `azim_int_settings.high_q_recipA`, `spot_finding_settings.high_resolution_limit` and `spot_finding_settings.low_resolution_limit` are no longer `required`. All three mean "no limit at that end" when unset and are omitted from the response instead of carrying a placeholder value, which raises in a client generated from an rc.160-or-earlier spec. A value of 0 is still accepted and means the same thing.
**Breaking changes to the stored formats** - a consumer reading these fields must treat them as optional:
* The per-image image-scale B factor is no longer computed, so `/entry/MX/imageScaleBFactor` is absent from newly written HDF5 files and the corresponding key is absent from the CBOR DataMessage and END blocks. Files written by rc.160 and earlier still contain it and still open; nothing in the pipeline reads it any more.
* `_reflns.jfjoch_diffrn_ISa` now carries the whole-range `1/sqrt(a*b)` that XDS's ISa denotes, and the error-model `a` and `b` are reported in XDS's convention; the strong-reflection asymptote moves to `_reflns.jfjoch_diffrn_ISa_asymptotic`. **A file written by an earlier version carries the asymptote under the plain `ISa` name.**
