+#           Ruby/Go/Rust/C/C++), so the bar is tightened back to ≤ 1.5×.
+#   Gate 4: SARIF schema validation on every dynamic verdict variant.
+#   Gate 5: Layering boundary test green.
+#   Gate 6: Java OWASP Benchmark v1.2 `--verify` acceptance.  Wall-clock
+#           ≤ 15 min on CI / ≤ 10 min on the dev reference machine; and,
+#           per OWASP cap backed by a sound runtime oracle, confirmed-rate

+#           R.0) added the precision/recall/budget ratchet.  The corpus is
+#           *not* checked into the repo; the gate skips with a clear message
+#           when `NYX_OWASP_CORPUS` does not point at a real checkout.
