The rc.166 changelog was missing fourteen user-visible changes and carried rationale and measurements that belong here instead. Added: the native miniCBF sweep reader, the third-party and firmware-1.x NXmx masters, the plain LZ4 filter, the image orientation taken from the file's module direction vectors, the two beam-centre flags and their rescues, and the FFT reach past 500 A. Trimmed the rest to one line each, moving the numbers out of the user-facing file. RUGNUX.md described the input as a single Jungfraujoch master file, which it has not been since this branch; it now covers the foreign and legacy masters, the accepted compression filters and the miniCBF sweep, including how a sweep is collected from one named frame. Six options existed with no entry in the table - --beam-center-check, --beam-center-search, --fft-min-unit-cell, --min-indexed-spots, --rot3 and --no-p1-crosscheck - and -C now moves both FFT cell bounds, which was not written down anywhere. CPU_DATA_ANALYSIS.md carried two statements this branch made false: 7.5 still said pass 2 reuses pass 1's space group, and 13.1 still said centrings are ranked by net absence count. Both now describe what the code does - the group is determined after pass 2, and centrings are ranked by the same Beta-tail likelihood the screw test uses. Also documents the per-zone screw scoring, the coplanarity volume-fraction guard, the plane-normal transform, the FFT cell bounds and the twelve refined candidates. The miniCBF reader implements the x-CBF_BYTE_OFFSET scheme and reads the imgCIF axis table from the specification alone. No CBF code is vendored or linked, so there is no licence obligation, but reimplementing a published specification carries one of credit: ACKNOWLEDGEMENT.md gains a section and the two algorithms carry a one-line reference each. Both DOIs were resolved before being written. Rottger's initial was wrong where this branch first cited it - K, not A.
