…moke (E5 substrate proof) native/metal_offscreen_smoke.m: standalone ObjC+Metal program — creates 64x64 MTLPixelFormatBGRA8Unorm offscreen texture, compiles inline MSL via newLibraryWithSource:, clears to blue + draws one red triangle, reads back pixels via getBytes, asserts px_clear=0x0000FFFF/px_triangle=0xFF0000FF/ nonuniform=1. SKIP path (exit 0) when MTLCreateSystemDefaultDevice() returns nil — honest ground-truth, not a failure. Local M4 result: __METAL_SMOKE__ PASS device=Apple M4 px_clear=0x0000FFFF px_triangle=0xFF0000FF nonuniform=1. Wire into CI (ci.yml) as warn-only step after E3 native interpreter, before CLI smoke — surfaces PASS/SKIP/FAIL in Blacksmith runner log without redding the build. Register in native/build.sh (ObjC ARC + Metal/Foundation flags). CHANGELOG + ARCHITECTURE.json blocking-frontiers updated (r10 substrate node added, E5 ladder updated to reflect Metal headless render empirically verified locally, CI pending). own1: plain Apple Metal — no Wine, no DRM, no game asset. Substrate proof only; validated_manjeom stays 0. r11 = D3D11 device/swapchain shim routing CreateDevice draws into this proven Metal offscreen path + minimal D3D11 test PE.

F-NSWINDOW-E5 r10 — ③ 게이트 "주장"→"실행 증명"
이전 턴에 'Metal 헤드리스 렌더 가능'이라 말만 했던 걸, 이제 실 Metal 렌더로 실행 증명합니다(verify-done·honesty·break-walls substrate 검증).
native/metal_offscreen_smoke.m(신규·235줄·ObjC+Metal)MTLCreateSystemDefaultDevice()→ nil이면__METAL_SMOKE__ SKIP reason=no_device(정직한 ground-truth·warn-only, 가짜 PASS 안 함).MTLTexture→ MSL 인라인 셰이더 파이프라인 → 파란 clear + 빨간 삼각형 1개 그리기 →getBytesreadback → clear색·삼각형색 둘 다 존재(non-uniform) assert.로컬 측정 (M4·exact stdout)
디스플레이 없이 실 GPU 프레임 렌더+읽기 확인 → ③ 게이트 경험적 검증 완료.
CI 배선 (warn-only)
ci.yml에 E3 step 다음 substrate step 추가. PASS/SKIP/FAIL 전부::warning::또는 로그(빌드 red 안 됨). 이 PR의 CI run이 Blacksmith GPU 세션 ground-truth(PASS=GPU 있음 / SKIP=세션 없음)를 줍니다.own1 / manjeom
gamebox 자체 삼각형을 자체 Metal 경로에 렌더 = substrate 증명, 게임 프레임 아님. validated_manjeom 여전히 0.
