Corrected policy holdout v5 MRR@10	1.0000
Office valid MRR@10	1.0000
Office holdout v3 MRR@10	1.0000
Legacy holdout v4 MRR@10	0.9444
Legacy policy all v2 MRR@10	0.9272

Representative throughput:

corrected policy holdout v5: 48.78 qps
corrected policy holdout v5 runtime-only: 50.78 qps
office holdout v3: 64.37 qps
office holdout v3 runtime-only: 68.86 qps
office valid: 66.76 qps

Why this release exists

v4 is the first public L6 fast reranker here where the model-side gain survives q8 deployment:

corrected broad holdout stays clean
office-holder holdouts stay clean
legacy broad-policy quality improves versus v3
throughput remains at the same critical-path class

Training note

The raw PT checkpoint also stayed clean on the corrected broad and office-holder gates. The critical deployment decision, however, was made on the q8 ONNX artifact.

Intentional gaps:

search-reranker-broad-v1: the local reports include strong fp32 ONNX proxy and office data, but not a matching fp32 in-domain finephrase / hard-K10 / holdout-A03 set, so those are not claimed here.
search-reranker-irishgov-l5-k10-v2: the local non-quantized reports are trustworthy for office / finephrase / hard-K10, but not for the same proxy runtime shape as the shipped q8 path.
search-reranker-irishgov-l6-fast-v1: the local non-quantized reports cover proxy and office, but not the fresh holdout-A03 slice used for the q8 K=10 comparison.
