From 2edaed8974d0bfb558bc98fdf1f16ee0fba761aa Mon Sep 17 00:00:00 2001 From: Remigiusz Antczak Date: Sun, 25 Oct 2026 02:36:02 +0100 Subject: [PATCH] Union the gitleaks default rules into the privacy gate and score it blind on held-out-3 The privacy gate now flags a file when either .banlist.txt or the gitleaks default rules match. The gitleaks port moved out of the rival bench into scripts/secret_scan.py, which the gate and score_rivals.py both import; the vendored v8.30.1 config (MIT, pinned in SOURCES.md) moved next to it as data. The exact-path frozen-corpus skip is kept and extended to held-out-3; 15 frozen paths holding only placeholders or synthetic values are allowed by exact path in scripts/secret-scan-allow.txt, so the repo stays at 0 hits. The gitleaks half fans out over 8 processes; wall time on this repo was 426s against 659s without it in one noisy back-to-back run. Held-out-3 (rules frozen, scored once, two rows given extra @@ markers before scoring and disclosed in the ledger): union 54/60 leaks FP 16/60, banlist only 41/60 FP 12/60, gitleaks 47/60 FP 8/60.
