Image buffer: the per-image CBOR metadata headroom had been re-derived from the online reflection cap alone, which cut it from 4 MiB to 2.55 MB while the measured worst case - reflections plus the capped spot list plus the three azimuthal arrays - is 2.9 MB, so the receiver dropped the frames with the most to say. Restore it and give it a name that both the code and its guard test read: written down twice, the two had drifted and the test kept passing against the value the code had left. Spot finding: an unset low_resolution_limit means no limit at that end, as an unset high_resolution_limit already did. An optional rather than a zero sentinel, because zero is not a natural "no limit" here - every pixel lies above it, so the plain comparison masked the whole image instead of none of it, and nothing validated the zero. The API field is no longer required; a zero is folded into the unset case at the boundary, where older clients still send it, so one spelling reaches the analysis code. The FPGA takes its fixed-point ceiling instead, since ap_ufixed<16,9> wraps above 512 A and would have masked everything. image_preprocessing: check the CUDA calls on the fused decode path - the one new GPU file with none, and the path fed by bytes we did not produce. An unchecked synchronise returned the host-written sentinel as if it were a measurement, so the decode looked successful and the fallback to the host decoder never fired. rugnux: --stride no longer writes one past the end of the per-image arrays, whose count floored where the worker loop ceils, and the written process file links the images actually processed rather than the first N - each frame's picture now sits next to its own analysis. Powder calibration: the face-centred calibrants no longer list their systematically absent rings, so the distance fit starts from a reflection that exists rather than an extinct one; the triclinic calibrant covers both signs of h and k instead of a single octant, which is only valid for a diagonal metric. The test asserted the old behaviour - one ring formula for every cubic standard - and is rewritten. CBOR: skip an unknown tagged value in the end block, as the other four blocks already do. One advance lands on the tagged item rather than past it, so an older reader fed a newer end message threw and never finalized its file. Viewer: a settings value the setter rejects no longer escapes as an uncaught throw from a worker slot, and the field offers only what the setter accepts. Space-group search: judge stage B on the same "present" cut stage A already computes. Merged sigma is floored so no reflection reads above ISa, so on a low-ISa merge the fixed cut left both stage B tests unsatisfiable - every screw axis passed unchallenged and the centering rescue switched itself off on exactly the weak data it exists for. Where the fixed cut is the smaller of the two they are equal and this is inert: over the 37-crystal rotation battery every crystal reports the identical space group and identical merge statistics, so it is a no-op there and the low-ISa case it targets remains unmeasured. rugnux: --polarization reaches --mode azint, which parsed the flag and then dropped it; that mode also applies the same polarization default as every other mode. Acknowledge the ACTS/traccc project, whose sparse connected-component labelling both spot extractors take their algorithm from, with its citation and its license. The rc.161 change list is brought back to one line per entry, and the user-visible changes that were missing from it added. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

third-party components, acknowledged below as required by their licenses.
This file is the human-readable manifest. The verbatim license texts live in the

These are downloaded by CMake (FetchContent / ExternalProject) during the first configure and

Frontend (npm) dependencies
The React/TypeScript frontend (frontend/) bundles a large transitive tree of npm packages,
overwhelmingly MIT/ISC/BSD/Apache-2.0 licensed. Their full notices are generated automatically:
cd frontend && npm run licenses # writes dist/THIRD_PARTY_LICENSES.txt
The generated file is produced as part of the frontend build target and installed alongside the
served frontend, so the shipped web UI carries its own attribution.
Notes on weak-copyleft and attribution-sensitive components
- MPL-2.0 (Eigen, GEMMI, libzmq, traccc): file-level copyleft. GEMMI is vendored in
gemmi_gph/in trimmed form; libzmq is fetched at build time; Eigen is provided externally (header-only). The corresponding source is available from each project upstream. - traccc is the one entry that is not a vendored directory. Its sparse connected-component
labelling enters two otherwise first-party files:
StrongPixelSet.cppadapts the SparseCCL source, andSpotExtractorGPU.cufollows the design of its GPU counterpart. MPL-2.0 is file-level, so both files name the origin at the top and are covered bylicenses/traccc.txt. See ACKNOWLEDGEMENT.md for the citation. - FFTW is GPL-2.0-or-later — compatible with, and absorbed by, this project's GPL-3.0 license.
- Apache-2.0 components: where upstream ships a
NOTICEfile, it is reproduced in the correspondinglicenses/text. - Qt (LGPL-3.0) and NVIDIA CUDA (EULA) carry redistribution conditions beyond a copyright
notice; see their dedicated notice files. The verbatim LGPL-3.0 and CUDA EULA texts are bundled
(
licenses/Qt6-LGPL-3.0.txt,licenses/NVIDIA-CUDA-EULA.txt); the CUDA EULA is the one shipped with CUDA Toolkit 12.8 — replace it if you build against a different toolkit version.
