+# Phase 27 (Track R.0): OWASP Benchmark v1.2 real-corpus acceptance.
+#
+# Runs Gate 6 of scripts/m7_ship_gate.sh against a real OWASP BenchmarkJava
+# checkout on every PR that touches the dynamic verifier (src/dynamic/), the
+# eval-corpus harness (tests/eval_corpus/), or the gate script itself.
+#
+# Gate 6 enforces, against the committed ground truth:
+#   * verify wall-clock <= 15 min (CI budget; the dev reference is 10 min),
+#   * per-cap confirmed-rate >= 40%, precision >= 0.85, recall >= 0.40 for the
+#     dynamically-supported OWASP caps,
+#   * the per-(cap,lang) budget in tests/eval_corpus/budget.toml.
+#
+# The corpus is *not* vendored.  It is cloned at the pinned 1.2beta tag (the
+# tag that produced expectedresults-1.2beta.csv, the source of the ground
+# truth) and cached so reruns skip the clone.
