Adds the supporting infrastructure — OffsetAllocator-backed GPU arenas (GpuResourceRegistry), a shared decoded-asset cache (AssetTable + TextureLoader), scene math and pipeline-state helpers, the flat scene state and packer (SceneGPUState), an offscreen RHI device and preview widget — then reworks the pipeline on top of it: the ISF parser and nodes gain 3D samplers, uniform inputs and geometry/vertex stages; the compute and raster pipelines become scene-aware with multiple render targets and auxiliary outputs; the render graph updates edges, render targets and passes in place instead of rebuilding wholesale; and the filter, texture-port, window, capture and video-output paths follow the new node and renderer interfaces.

Cabling a producer that publishes a storage buffer -- any `storage` RESOURCE exposes a Types::Buffer output -- is a graph a user can build, and we were binding it: vkUpdateDescriptorSets then rejects the write with VUID-VkWriteDescriptorSet-descriptorType-00330 and the next setShaderResources segfaults. OpenGL has no descriptor sets, so nothing caught the mismatch there and the shader read whatever that binding exposed. Check the usage and keep the zero-filled placeholder instead, with a warning naming the input. The invalid graph no longer renders correctly -- a storage buffer is not a UBO -- but it is now defined and diagnosable on every backend rather than a crash on one and silent garbage on the other.

SceneGPUState.cpp and CameraMath.cpp are compiled straight into the test targets: score_plugin_gfx is built with hidden visibility and exports neither. This is the workaround tests/gfx/CMakeLists.txt already applies to ISFNode.cpp et al; src/ is not modified. CameraUBOData's field offsets are pinned, not only its size: two out-of-tree tester shaders encode a 208-byte camera entry against this 240-byte one, so the ABI drift is live rather than hypothetical. Two findings recorded as assertions rather than fixed: - FlatScene's doc-comment says the no-camera fallback eye is (0,1,3); SceneGPUState.cpp writes (0,0,3). The test pins the code. - FlatScene::clear() resets the containers and the two flags but not viewMatrix / projectionMatrix / cameraPosition / cameraFov / cameraNear / cameraFar, and the empty-scene path returns before the fallback block would rewrite them, so a reused FlatScene keeps the previous scene's camera on it. hasCamera is the only reliable signal, and the test says so. Negative controls, each seen red before being trusted: - parentWorld * xform -> xform * parentWorld makes the parent-on-the-left case red (1.0 instead of 2.0). A translation-only hierarchy cannot catch this — translations commute — so that case uses a scale. - dropping the raw_slot.size guard on the light arena slot makes the producer-less sentinel case red (0 instead of 0xFFFFFFFF). - negating out(2,2)/out(2,3) in setReverseZPerspective turns 203 of the 286 camera assertions red.

charset=UTF-8 Content-Transfer-Encoding: 8bit Covers 45d1202327 (pland/scene). ScenePreprocessor's packAndUploadCameras packs one CameraUBOData per camera the flattener collected into m_camerasBuffer — capacity at least 16 of them — and puts the active camera at slot 0. Both publication sites then advertised the `camera` auxiliary's byte_size as a bare sizeof(CameraUBOData): 240 bytes, exactly one entry, however many were packed. A MULTIVIEW shader indexing camera[gl_ViewIndex] over six cubemap faces reads outside the range its binding declares — undefined, and on Vulkan a validation error rather than the intended faces. The engine is NOT fixed here. What the two literals become is one named inline function, cameraAuxByteSize(cameraCount), called from both sites with the count that was actually packed; today it ignores its argument and returns sizeof(CameraUBOData), so the generated code is unchanged. That is the whole production diff, and it exists so the contract has somewhere to be asserted and, later, one place to be fixed. test_unit_scene_camera_aux is its own target, in the style of test_gfx_isf_findings, so an attributable RED cannot take down the flattener suite next door. the camera auxiliary covers every camera the flattener packed CHECK( cameraAuxByteSize(out.cameras.size()) == (int64_t)(out.cameras.size() * sizeof(CameraUBOData)) ) with expansion: 240 == 1440 (0x5a0) The single-camera case passes, which is why nothing has noticed. Making cameraAuxByteSize return max(1, count) * sizeof(CameraUBOData) turns the whole target green, so this is a gate on the defect and not merely a broken assertion — the mesh path's wrapGpu(m_camerasBuffer, sizeof(CameraUBOData)) slice has to grow with it.

Depth after the viewport transform is in [0, 1], so under `less` that clear admits no fragment at all and under `less_equal` only the single plane at exactly 0.0: the first draw into the target is entirely rejected and the frame stays at the clear colour, with no diagnostic. tests-scene's ps-depth-test.fs declares exactly that, and ShaderSweepScene records "nothing drawn" as an unasserted observation in a file that SKIPs in every clean checkout. The engine is NOT fixed here. The two literals become one exported function, depthClearForCompare(compare), called from both sites with the convention's own Greater; today it ignores its argument and returns 0.0f, so the generated code is unchanged. That is the whole production diff, and it is the seam the fix goes through. The test states the property rather than the value: a (clear, compare) pairing is usable when every depth sampled over [0, 1] except at most the clear plane itself draws into a freshly cleared target. Under that predicate `greater`, `greater_equal` and `always` pass, `never` correctly does not, and: a shader declaring a less compare gets a clear it can pass CHECK( clearIsUsableBy(toCompareOp(s)) ) -> false [DEPTH_COMPARE: less] CHECK( clearIsUsableBy(toCompareOp(s)) ) -> false [less_equal] CHECK( clearIsUsableBy(toCompareOp(s)) ) -> false [lequal] the depth clear differs between the two compare directions CHECK( depthClearForCompare(Less) != depthClearForCompare(Greater) ) with expansion: 0.0f != 0.0f Returning 1.0f for Less/LessOrEqual turns the target green, so this gates the defect rather than merely asserting something false.

CLIP_DISTANCES / CULL_DISTANCES were emitted as bare globals — `out float gl_ClipDistance[N];` — but both built-ins are already declared inside gl_PerVertex, so that is a redeclaration changing their qualification and glslang rejects it: "cannot change qualification of gl_ClipDistance". Every shader using the feature failed to build, and nobody noticed, because the strings CLIP_DISTANCES / CULL_DISTANCES / gl_PerVertex appear nowhere under tests/ and no corpus shader declares either. Four cases, all parser-level, no GPU and no app, in the file that already owns the libisf parser surface. The load-bearing one is negative: CHECK(!contains(vert, "out float gl_ClipDistance")) — that is what the pre-fix emitter produces. The clamp behaviour is asserted as the code has it, not as the commit message describes it: isf.cpp accepts 1..8 and otherwise leaves the count at zero, so an out-of-range count emits no block at all rather than a clamped one. Negative control: restoring the bare-global emission in isf.cpp turns 8 assertions across 2 of the 4 cases red, including both `!contains` guards.
