Mirrors seekstone#305: the retrieval runner never measured the 8M default through the real search tool, so the published row was the in-harness scan without the MaxSim rerank. Re-measured end-to-end 2026-09-04, same-run head-to-head refreshed via local Ollama.

Changes on /benchmarks

  • Metric cards: 74% → 88% hit@5 on description-style queries; ~15 ms → ~35 ms warm semantic (the honest correction runs both directions — the old latency was also scan-only); quality-mode sub 64 → 63 ms.
  • Comparison table, all rows re-sourced from the refreshed committed run: 8M row now 84.0% / 85.0% / 35 ms / 41 s (labeled "8M + MaxSim"); 32M 63 ms / 38 s; tc 15.9 KB / 36 min; tc-graph 833 ms (p95 4.0 s) / 15.3 KB; mcp-pro ~23 min crash.
  • Honest-read paragraph + embedding-pass note (~40 s) + re-benchmark date updated.
  • faq.ts: semantic latency ~14 ms → ~35 ms with the MaxSim rerank.

Every competitor quality number reproduced exactly; gate-v2 verdict unchanged (fail — published miss stands). Site builds clean.

… 74% (SHA-323)

The default-model row was the in-harness scan without the MaxSim rerank.
Measured through the real search tool (seekstone#305, re-run 2026-09-04):
84.0% overall / 85.0% held-out / 88% on description-style queries at
~35 ms warm p50 — the latency correction is honest in the other
direction (the old ~15 ms was also scan-only). Competitor rows refreshed
from the same re-run so the 'same run' claim stays true; gate-v2 verdict
unchanged.
