Trained checkpoints whose Quirk Expression Rate (QER) tracks the integrated-DPO (IDPO) reference at several levels (spec military_submarine_synth_preference), reproduced under training seed 2137: each branch re-trains the same recipe and training steps the seed-42 auto-search found for that level, with this seed's RNG and no re-matching. A different seed drifts the trajectory, so the listed value is the measured seed-2137 QER — near, but not re-fitted to, the seed-42 band. Branch step-<N> corresponds to the IDPO step-N QER level.
