Prediction applied a mosaicity/profile-radius moving average (RotationParameters) over the last N *processed* frames. Under the parallel per-image loop that window is thread-arrival order, so the smoothed value - and hence which reflections are predicted/integrated - was non-deterministic run-to-run, swinging CC1/2 (and even the space group) on marginal crystals. `-N 1` was deterministic; `-N 32` was not. Fix (as designed with FL): prediction now uses each frame's OWN mosaicity/profile-radius (image-local, deterministic membership - a reflection on the cutoff contributes ~nothing). The smoothing that actually matters is moved into RotationScaleMerge and done in FRAME order (deterministic): per-frame mosaicity is smoothed with the same window as smooth-G, then every partial's partiality is recomputed from it BEFORE the 3D combine. This is the mosaicity analogue of smooth-G: combining a reflection's per-frame partials only tiles the rocking curve correctly (captured fractions summing toward 1) if neighbouring frames share a consistent mosaicity. Battery (18 crystals, /data/rotation_test, 2 runs each): 15/18 now bit-identical run-to-run (the good crystals unchanged - lyso P41212 ISa 7.8 CC1/2 99.7%). The 3 residual crystals (EcwtAL500, EcwtCQ066S, pding4_003 - all large/triclinic cells) still jitter ~0.002%, traced to a SEPARATE, benign cause: the GPU prediction buffer overflow (BraggPredictionRotGPU max_reflections=10000 with a racy atomicAdd/atomicSub) on dense frames - cell/space group stay stable; to be addressed in the GPU prediction/integration rework (naively raising the cap also changes prediction quality, so it is not a one-line bump). Minor label refinements from the recomputed partiality: cytC_2 P321 -> P3121 (now consistent with cytC_3), Ins_I_2/3 report the honest I23/I213 screw-axis ambiguity.
