Runs `2026-08-16-r1`/`-r2` · region `ap-south-1` · ground truth frozen 2026-08-16T17:20:32Z sha256 `011da0f8…0cb7d28`.
Modes: search. Reproducible from `serper/input-*/outputs/raw/<mode>/<Qxx>.json`.

**How to read this.** `top3 PASS/FAIL` asks only whether one hand-picked ground-truth URL appeared in the first 3 results — a FAIL does not mean the tool was wrong. Citation `unreadable` means our checker could not fetch the page (paywall, JS shell, PDF, 403, non-English); only `**FALSE**` means read and unsupported. Grades tagged `graded_by=claude-pass-1` are one model reader's pass, not a human sign-off.
