+# Phase 1.0CQ: full-output native SDL one-shot gate
+
+Status: `CONFIGURE_PROVEN_FULL_BUILD_OUTPUT_BOUND_ONE_BUILD_ALLOWED`
+
+Date: 2026-07-30
+
+The CP correction is committed and tested; the native root is absent. CQ
+permits one native-SDK materializer invocation with the proven 1,800-second
+configure bound and a 1,048,576-byte SDL-build output cap. Scope ends at the
+native static archive; export, RetroArch target and PS5 actions remain excluded.
