repair for Temporal flicker on alpha-tested +Sodium terrain, specifically leaves and grass. The intended fix is not a +material-name special case: every Sodium non-translucent terrain pass using the +same `ALPHA_CUTOUT=0.5` discard contract writes exact post-discard coverage to a +separate R8 MRT attachment. A compute pass expands that coverage by the current +jitter/upscale footprint and merges it into the MetalFX reactive mask. + +Work intentionally stopped at the user's request. Do not claim the Minecraft +renderer path is validated yet. + +Repository: + +```text +/Users/retriedstormtrooper/Documents/Projects/Active/MinecraftMetal/MetalUniversal-master +``` + +The repository currently has no usable committed baseline: `git status --short` +reports the entire tree as untracked. Preserve it. Do not reset, clean, or treat +an empty Git diff as evidence. + +The fail-closed gate is still correct: + +```java +private static final boolean OBJECT_MOTION_PRODUCER_CONNECTED = false; +``` + +It is at +`src/main/java/com/metallum/client/metal/render/MetalFxManager.java`. + +## Why the old implementation flickered + +Leaves and grass are rendered by Sodium's CUTOUT terrain path into the ordinary +opaque scene target. They do not pass through Minecraft's later translucent, +particle, weather, cloud, or item-entity targets. The existing reactive-mask +inputs therefore missed their rapidly changing alpha-tested coverage. + +A 3x3 depth-edge heuristic is insufficient: subpixel alpha coverage can change +under Temporal jitter without producing a stable depth discontinuity in the +same input pixel. Treating zero motion as a substitute would also be wrong. + +The source path inspected in this checkout was: + +```text +DefaultChunkRenderer.render +→ ShaderChunkRenderer.begin / compileProgram +→ Sodium blocks/block_layer_opaque shaders +→ non-translucent fragment-discard pass +→ ALPHA_CUTOUT=0.5 +``` + +The new fragment shader copies Sodium's atlas sampling/RGSS logic and performs +the same cutoff before writing both outputs.

The frame-graph pass is +scheduled after the transparency post chain and before the always-on-top pass, +so the source targets remain alive until the mask has been generated. + +The Java 26.2 client does not contain the Bedrock/other-client `Vibrant Visuals` +option name.

Mode, 50/67/100% scene scale, transparent-target +reactivity, and frame generation are persisted outside Sodium's private option +classes and require a full game restart. This matches the actual renderer +lifetime: the main scene target is constructed during `GameRenderer` creation, +while the native MetalFX scaler is cached by device/format/dimensions. + +The current render backend creates samplers from Minecraft's `GpuSampler` +contract. That contract carries filtering, anisotropy, and max LOD, but no +negative LOD bias. The cross-shader path is generated from SPIR-V at runtime; +there is no material-only sampling hook where a negative bias can be applied +without rewriting generated MSL. MIP bias is therefore documented as an +unimplemented quality optimization rather than approximated with a global +shader rewrite. + +On 2026-07-26 the official Java transparency path was exercised with +`improvedTransparency:true` and `graphicsPreset:"custom"`. OFF, Spatial 0.67, +Temporal 0.67, and Temporal 0.67 with frame generation all entered `New World`. +The temporal runs reported all five transparency targets and produced no new +crash report.

If the transparency frame-graph pass is unavailable, the motion +pass starts the reactive value at zero instead of retaining stale mask data from +the previous frame. + +The motion and transparency compute passes use the device-reported thread +execution width (capped at a portable 64-wide upper bound) and keep their +pipelines cached.

`translucent`、`item_entity`、`particles`、`weather`、`clouds` 等目标（Minecraft 26.2 映射：`/tmp/minecraftmetal-mc26-sources/net/minecraft/client/renderer/LevelRenderer.java:163-260,365-510`；目标集合：`/tmp/minecraftmetal-mc26-sources/net/minecraft/client/renderer/LevelTargetBundle.java:12-90`）。`MetalFxManager.beforeGuiInternal` 在 GUI 之前把这个场景 target 编码到 `uiTarget` 或 Frame Generation 的 `sceneOutputTarget`（当前代码：`/Users/retriedstormtrooper/Documents/Projects/Active/MinecraftMetal/MetalUniversal-master/src/main/java/com/metallum/client/metal/render/MetalFxManager.java:393-516`）。之后 `GuiRenderer.draw` 被 redirect 到原生分辨率 `uiTarget`（`GuiRendererMetalFxMixin.java:12-22`），最后由 `MinecraftMetalFxMixin` 和 `MetalSurface` 走 drawable present（`MinecraftMetalFxMixin.java:29-45`；`MetalSurface.java:62-68`）。 + +```mermaid +flowchart LR + A["Minecraft.renderFrame / GameRenderer.render"] --> B["LevelRenderer FrameGraph"] + B --> C["main

资源、jitter、history reset 和 `encodeMetalFxV2` 接入。mode 选择要求 MetalFX Temporal support 与 `metallum_metalfx_supports_motion_v2` 同时为真（`MetalFxManager.java:249-257`）；资源创建和对象输入清零位于 `MetalFxManager.java:642-700`，Java V2 调用位于 `MetalFxManager.java:456-479`，native V2 export 和 camera/merge compute 位于 `MetallumNative.swift:1355-1508,1844-2011`。 + +V2 的当前实际数据流是：camera kernel 从 depth 和 current/previous camera 矩阵写 `cameraMotionTexture`/`disocclusionTexture`；`objectMotionTexture` 与 `objectValidityTexture` 在世界绘制前被清零，当前生产代码没有 renderer 对它们写入；merge 因此选 camera motion，并把 disocclusion/depth edge 合并进 reactive。`MetalMotionStateStore.observe`、`MetalMotionContract.projectVertex` 只有定义/测试调用，没有生产 producer（`MetalMotionStateStore.java:31-44`；`MetalFxManager.java:53,301,547`；`rg` 未发现 `observe` 的生产调用）。所以动态实体、Sodium 区块顶点动画、粒子运动和 alpha-cutout 风动仍没有真实对象 motion。 + +**总体判断：strong_inference。** V2 resource/compute/bridge topology 由源代码和当前 macOS/iOS bundled dylib 的 `nm -gU` 符号交叉确认；对象 producer 缺失由负向调用搜索确认；画质、抖动和拖影仍需真机视觉验证。 + +## Motion 覆盖范围 + +| 内容 | 当前 motion 证据 | 判断 | +| --- | --- | --- | +| 静止几何 + 相机平移/旋转 | native `metallum_motion_reconstruction` 使用 inverse current jittered

+**结构上是，语义上有边界。** `GameRendererMetalFxMixin.beforeGui` 在 `GuiRenderer.render` 前执行 MetalFX；`GuiRendererMetalFxMixin.draw` 将 GUI 的 `mainRenderTarget()` redirect 为 native-resolution `MetalFxManager.guiTarget`（`GameRendererMetalFxMixin.java:78-84`、`GuiRendererMetalFxMixin.java:12-22`）。因此 HUD、聊天、菜单和正常 GUI 不进入 Temporal history。第一人称手、屏幕效果、feature rendering、3D crosshair 位于 `GameRenderer.renderLevel` 内，属于场景侧而不是 GUI 侧（`GameRenderer.java:547` 及 `LevelRenderer.render` 调用链）。 + +**置信度：confirmed for code ordering；限制：没有逐个 GUI 层的 GPU capture。** + +## 透明内容当前处理 + +直接 reactive 来源是 `translucent`、`itemEntity`、`particles`、`weather`、`clouds` 五个目标，注入点为 `LevelRenderer.addAlwaysOnTopPass` HEAD（`LevelRendererMetalFxMixin.java:17-25`；`MetalFxManager.java:518-566`）。native `metallum_metalfx_mark_transparency` 使用近二值 alpha/color 检查，再叠加 3x3 depth validity/gradient heuristic（`MetallumNative.swift:1098-1126,1175-1209,1211-1265,1346-1398`）。这不是对象运动 mask，也不是连续材质分类；alpha-cutout 和实体 motion 仍缺真实输入。 + +## Frame Generation 当前结构 + +Frame Generation 的 native presenter 结构存在，但当前 Java gate 明确关闭：`OBJECT_MOTION_PRODUCER_CONNECTED=false`（`MetalFxManager.java:29-33`），而 `frameGenerationEnabled` 还要求该常量为真（`MetalFxManager.java:99-116`）。因此当前工作树的实际 present 不会进入 `frameGenerationInputInternal`；`MetalFxManager.java:790-822` 和 `MetallumNative.swift:65-221,2013-2095` 是 dormant/conditional path。该 path 若以后被打开，Java 提供 pre-GUI scene color、post-GUI composed UI color、scene depth、merged motion、jitter、FOV、near/far、aspect 和 reset；native 复制到三个 private slots，由 `MetalFX PresentThread` worker 消费，并由 `readyEvent` 连接输入 command buffer 与 present queue。`maxOutstandingFrames` 实际为 1；`frameDuration` 在 presenter 创建时按 `NSScreen.maximumFramesPerSecond` 采样，缺省 60、下限 30，真实帧用 `afterMinimumDuration(frameDuration * 0.5)`（`MetallumNative.swift:89-94,165-174,724`）。没有运行时 display timing/VRR 回调，最终扫描时序仍需真机验证。 + +## 最危险的五个问题 + +1. **动态内容没有对象 motion producer（confirmed absence in inspected bridge）。** V2 object motion/validity attachment 会被清零，`MetalMotionStateStore` 也没有生产观察调用；叶片风动、实体、粒子只能依赖相机 motion 和 reactive/depth heuristic。 +2. **尺寸契约有运行时反证（confirmed runtime artifact）。** 历史 crash 记录 GUI scissor `1708x524` 被应用到 `1144x642` render area；说明至少某条 GUI/scissor 路径仍混用 display/render 尺寸。报告不能把当前代码中的尺寸函数当成已解决证明。 +3. **当前内置 pipeline 没有 motion MRT contract，但通用 Metal backend 本身已支持 indexed 多附件（confirmed with boundary）。** `RenderPipeline`/`RenderPass` 支持最多 8 个 color slots，Java encoder、`MetalRenderPass`、`MetalCompiledRenderPipeline` 和 Swift v2 bridge 都逐槽传递；当前 Minecraft 26.2 与 Sodium 0.9 已枚举 pipeline 仍只声明 slot 0（`RenderPipeline.java:147-159,241-255`；`RenderPass.java:82-98`；`MetalCommandEncoder.java:134-180,205-227`；`MetalCompiledRenderPipeline.java:114-125,187-216`；`MetallumNative.swift:2484-2580,3214-3275`；`RenderPipelines.java` 43 个无 index 调用；`ShaderChunkRenderer.java:51-66`）。增加 motion MRT 的缺口在 pipeline/shader/FrameGraph contract 和 Temporal input 接线，而不是“native 只能绑定一个附件”。 +4. **Frame Generation 当前被常量 gate 关闭，pacing 只存在于 dormant presenter（confirmed source; runtime behavior unknown）。** `OBJECT_MOTION_PRODUCER_CONNECTED=false` 使当前 Java 不进入 FG；若后续打开，pacing 只在 presenter 创建时采样屏幕刷新率，没有 VRR/presentation timestamp 回调。 +5. **没有 Git 基线且 native build 输出位于 tracked resource 路径（confirmed risk）。** build task 输出 `src/main/resources/natives/{macos,ios}/libmetallum.dylib`（`build.gradle:53-74,109-132`），本次历史构建可能重写二进制；由于仓库没有 Git，无法可靠判定前后差异。 + +## 证据最强的五个结论 + +1. **真实低分辨率场景存在。** `sceneWidthInternal/sceneHeightInternal` 选择 scaled target（`MetalFxManager.java:263-270`），历史日志记录 Temporal `input=1144x642, output=1708x960`；交叉证据是 `ensureTargets` 与 `beforeGuiInternal`（`MetalFxManager.java:578-630,393-516`）。 +2. **GUI 在 MetalFX 后合成。** 注入点和 target redirect 均在当前代码中明确（`GameRendererMetalFxMixin.java:78-84`、`GuiRendererMetalFxMixin.java:12-22`）。 +3. **motion 约定是 previous-screen minus current-screen。** native MSL/Java mirror 和日志明确打印该 convention，数学实现为 `previousClip - currentClip`（`MetallumNative.swift:1211-1264`；`MetalFxMath.java:120-157`；`latest.log:111`）；单测覆盖方向（`MetalFxMathTest.java:57-93`）。 +4. **reactive mask 的直接输入只有五类透明目标。** Java 取五个 `LevelTargetBundle` handles，native 处理 binary alpha/color 加 depth heuristic（`MetalFxManager.java:518-566`、`MetallumNative.swift:1098-1126,1175-1209,1211-1265,1346-1398`）。 +5. **Frame Generation 的 dormant contract 使用 pre-GUI scene 与 post-GUI composed UI 两份颜色。** Java 的 `frameGenerationInputInternal` 与 native slot/export 结构交叉支持该条件路径，但当前 gate 为 false（`MetalFxManager.java:790-822`；`MetallumNative.swift:81-87,2013-2095`）。 + +## 仍未知或需要运行验证 + +- Minecraft 窗口在所有 resize、Retina scale、全屏和 GUI scissor 状态下的真实 pixel/viewport 值。 +- MetalFX driver 对 motion 纹理的实际采样、depth sampling、jitter 最终画面响应和 reactive strength 的运行时表现；motion 的方向/像素 scale 已由本地 Xcode 26.5 SDK 契约与 native producer 交叉确认，但仍没有 GPU capture。 +- Sodium 之外的模组 shader、实体局部动画和第三方 renderer 是否绕过当前 backend。 +- 当前进程实际加载的 native dylib、`SymbolLookup` 返回的 V2 symbols，以及当前运行到底选择 Temporal/Spatial；bundled macOS/iOS 文件的 `nm -gU` 结果已确认 V2 symbols 存在，但没有 runtime loader trace。 +- 每个 runtime `RenderPipeline` 的完整枚举和真实 shader key 集合。 +- Frame Generation 在刷新率改变、VRR、窗口隐藏、应用后台和 drawable timeout 下的实际行为；`maximumFramesPerSecond` 只在 presenter 初始化采样。 +- 本轮 `buildMacNative`/`buildIOSNative` 生成的 dylib 与构建前二进制是否字节不同；无 Git 基线不能作 diff 结论。 + +## Sol 优先级 + +1. 先确认当前进程加载的 native dylib、V2 capability 和实际 `effectiveMode`，再复现 display/render/GUI viewport 契约和 Temporal jitter/motion 的真机 capture。 +2. 在不改功能的前提下枚举 runtime pipeline，确认 cutout、entity、particle 和 Sodium terrain 的 object attachment/validity 是否始终为空。 +3. 再决定树叶/实体的 reactive、velocity replay 或 MRT 边界；当前最小事实边界是 `MetalFxManager` V2 resource preparation、`MetalMotionStateStore`、`MetalCommandEncoder.encodeMetalFxV2`、`MetalCompiledRenderPipeline` 和 native `metallum_metalfx_encode_v2`。 +4. 只有在 object producer 接通且 FG gate 明确后，才验证 Frame Generation pacing 与 drawable timing，先测 `maximumFramesPerSecond`、`afterMinimumDuration`、VRR 和 drawable 时间戳。 +5. 最后才处理 Sodium UI/config 和兼容性；它们不是当前 motion 根因的直接证据。 + +## 首轮报告索引 +

(`/Users/retriedstormtrooper/Documents/Projects/Active/MinecraftMetal/MetalUniversal-master/src/main/java/com/metallum/client/metal/render/MetalFxConfig.java:171-190`). Existing tests prove current expected values: 1920 at 1.0, 1286 at 0.67, 960 at 0.5, and phase counts 8/18/32 (`src/test/java/com/metallum/client/metal/render/MetalFxMathTest.java:103-110`). The exact odd-size rounding and alignment behavior is not reproduced here; it must be tested with odd display dimensions and 0.67/0.5. No source evidence in this first pass proves an 8-pixel alignment constraint. + +## Aspect ratio and projection + +`MetalFxManager.prepareSceneProjectionInternal` saves the final Mojang projection and calls `MetalFxMath.adjustPerspectiveAspect` with display aspect and render aspect before jitter (`MetalFxManager.java:303-363`; `MetalFxMath.java:71-90`). This is intended to preserve the display camera while rendering a lower-resolution target. The projection input is therefore not simply “display projection”; its exact matrix also includes Mojang camera effects and the current render-state path. + +**Potential mismatch:** Minecraft `GameRenderer.mainRenderTarget.width/height`, GUI scissor, surface drawable size and MetalFX output can be different logical layers. Historical crash `crash-2026-07-26_02.17.39-client.txt` recorded GUI scissor `1708x524` against `1144x642`, which is direct runtime evidence that at least one path mixed native and scene dimensions. This is not resolved by the existence of `sceneWidthInternal` alone. + +## Viewport/scissor + +`MetalRenderPass` defaults scissor to the first non-null color texture dimensions and also accepts render area values (`/Users/retriedstormtrooper/Documents/Projects/Active/MinecraftMetal/MetalUniversal-master/src/main/java/com/metallum/client/metal/render/MetalRenderPass.java:33-80,532-548`). Native v2 render encoders bind the indexed color array and set the viewport (`MetallumNative.swift:2484-2580`). The current code does not provide a first-round proof that every caller's render area is in the same coordinate space as the bound texture; the historical GUI crash is the counter-evidence. This is a size/scissor issue, not evidence that the backend collapses MRT to attachment 0. + +## Resize/fullscreen/Retina order + +1. `GameRenderer.render` observes window render-state mismatch and calls `GameRenderer.resize` (`GameRenderer.java:423-430`). +2. `GameRenderer.resize` resizes main target and calls `LevelRenderer.resize` (`GameRenderer.java:317-320`). +3. Mixin redirects target construction/resize and reports width/height to `MetalFxManager` (`GameRendererMetalFxMixin.java:16-77`). +4. `MetalFxManager.ensureTargets` updates scene/UI dimensions, recreates targets/aux textures, and resets history on dimension change (`MetalFxManager.java:578-630`). + +The exact order of `CAMetalLayer.drawableSize`, Java window state, GUI logical scale and in-flight native Frame Generation drain is not proven in this first round. A Retina change while a native FG slot is outstanding is therefore an explicit unknown, not a completed lifecycle guarantee. + +## Coordinate conventions + +- JOML/NDC matrix path uses the Java `Matrix4f.get(float[])` -> native scratch -> Swift `makeMatrix` path for Temporal motion; no separate row-major transpose is present in the inspected bridge. Frame Generation input itself carries textures and scalar camera parameters rather than VP matrices (`MetalCommandEncoder.java:293-335`; `MetalNativeBridge.java:803-835`; `MetallumNative.swift:1270-1277,1473-1493`; `MetalFxManager.java:707-740`). +- Runtime motion reconstruction converts pixel center to top-left screen/NDC with `currentNDC.y = 1 - 2 * pixelY/height` in native `metallum_motion_reconstruction` (`MetallumNative.swift:1211-1264`); `MetalFxMath.reconstructMotion` is the Java mathematical mirror used by tests (`MetalFxMath.java:120-157`). +- Native MSL/present has an explicit vertical-orientation helper/comment for `CAMetalLayer` (`MetallumNative.swift:947-1000`); the exact copy shader transform should be captured before any implementation change. + +## Narrowed evidence: pixel size, logical GUI size, and scissor contract + +**Confirmed:** the Minecraft value passed into `GameRenderer`'s `WindowRenderState.width/height` is framebuffer pixel size, not window-point size. `Window.getWidth()` and `getHeight()` return `framebufferWidth/framebufferHeight` (`/tmp/minecraftmetal-mc26-sources/com/mojang/blaze3d/platform/Window.java:462-468`); `GameRenderer.extractWindow()` copies those values into `WindowRenderState` (`/tmp/minecraftmetal-mc26-sources/net/minecraft/client/renderer/GameRenderer.java:612-620`). GUI logical size is a separate `guiScaledWidth/guiScaledHeight`, derived from framebuffer size and the GUI scale (`Window.java:433-440,486-503`; `Minecraft.java:1410-1422`). Retina backing scale is therefore already folded into the width/height values before MetalUniversal receives them; no separate Java-side backing-scale field enters the MetalFX manager in the inspected path. + +**Confirmed:** in an active scaled mode, the same framebuffer pixel dimensions feed three different contracts: + +1. `GameRendererMetalFxMixin` redirects `MainTarget` construction and `RenderTarget.resize` to `sceneWidth/sceneHeight`, so the main scene target is lower resolution (`/Users/retriedstormtrooper/Documents/Projects/Active/MinecraftMetal/MetalUniversal-master/src/main/java/com/metallum/mixin/render/GameRendererMetalFxMixin.java:17-31`). +2. `GameRenderer.render`'s width/height field reads are redirected to `MetalFxManager.reportedWidth/reportedHeight`, which return the stored display dimensions rather than the low-resolution target dimensions (`GameRendererMetalFxMixin.java:34-48`; `MetalFxManager.java:125-135`; mapped `GameRenderer.java:419-444`). This is a deliberate compatibility shim, but the redirect is method-wide and has no ordinal/local distinction. +3. `prepareSceneProjectionInternal` receives those display dimensions, derives render dimensions, adjusts the projection aspect from display to render aspect, then applies jitter (`MetalFxManager.java:285-364`). The hand projection separately uses `WindowRenderState.width/height`, i.e. display pixel dimensions (`/tmp/minecraftmetal-mc26-sources/net/minecraft/client/renderer/GameRenderer.java:588-594`). + +**Confirmed:** the generic render-pass default is texture-sized, while explicit scissor values are not rescaled by the Metal backend. Mojang's `CommandEncoder.createRenderPass` creates a full-texture `RenderArea` from the bound color texture (`/tmp/minecraftmetal-mc26-sources/com/mojang/blaze3d/systems/CommandEncoder.java:59-85`; `RenderPass.java:322-327`). `MetalRenderPass.pushEffectiveScissor` intersects the caller's `ScissorState` with that area using raw integer coordinates (`/Users/retriedstormtrooper/Documents/Projects/Active/MinecraftMetal/MetalUniversal-master/src/main/java/com/metallum/client/metal/render/MetalRenderPass.java:527-549`). There is no scale conversion in that function. Therefore a display-sized scissor submitted while the active color target is the scaled main target can exceed or collapse against the target; the historical GUI validation failure is consistent with this, but the source alone does not prove that every caller supplies display-sized coordinates. + +**Confirmed:** native surface configuration uses the width/height supplied by Java surface configuration as `CAMetalLayer.drawableSize`, sets the layer pixel format to `.bgra8Unorm`, and does not query or derive the size from `contentsScale` (`MetalSurface.java:31-49`; `MetallumNative.swift:2859-2871`). On iOS the existing host layer's `contentsScale` is intentionally left under launcher control, while `drawableSize` remains the renderable size (`MetallumNative.swift:1978-2005`). This separates layer drawable size from Minecraft GUI logical size. Exact runtime equality between drawable pixels and the Java framebuffer values still requires a live log or capture. + +**Confidence boundary:** the size propagation and absence of backend scissor rescaling are `confirmed` by source. The claim that a particular GUI or world pass is wrong is `strong_inference`, supported by the recorded `1708x524` versus `1144x642` validation failure (`crash-2026-07-26_02.17.39-client.txt` and `run/logs/latest.log`), but needs a capture naming the pass and its bound texture. The exact odd-size behavior is source-confirmed for `Math.round` followed by clearing the low bit (`MetalFxConfig.java:182-194`), but its effect on a particular projection/viewport pair remains unverified. diff --git a/docs/render-pipeline-forensics/05-matrices-jitter-motion-conventions.md b/docs/render-pipeline-forensics/05-matrices-jitter-motion-conventions.md new file mode 100644 index 000000000..e32e6936e --- /dev/null +++ b/docs/render-pipeline-forensics/05-matrices-jitter-motion-conventions.md @@ -0,0 +1,103 @@ +# 矩阵、jitter 与 motion 约定 + +> **2026-07-26 status:** motion 方向、top-left Y 和 jitter exclusion 仍沿用本文合同；普通实体 producer 与数值 readback 已接入，当前证据见 `../metalfx-motion-pipeline-implementation.md`。 + +## 矩阵来源与更新时间 + +| 矩阵/状态 | 来源与更新时间 | 当前用途 | 置信度/限制 | +| --- | --- | --- | --- | +| Mojang final projection | `GameRendererMetalFxMixin` 在 `GameRenderer.renderLevel` projection 参数处调用 `MetalFxManager.prepareSceneProjection`；manager 保存 `projectionMatrix` 到 `currentProjection`（`/Users/retriedstormtrooper/Documents/Projects/Active/MinecraftMetal/MetalUniversal-master/src/main/java/com/metallum/mixin/render/GameRendererMetalFxMixin.java:59-77`；`MetalFxManager.java:285-312`） | 场景投影，含 Mojang 的 bob/hurt/screen effects 结果 | confirmed path;

For each valid depth pixel, `metallum_motion_camera_v2` reconstructs world position through `inverseCurrentViewProjection`, projects it with the unjittered current and previous VP matrices, and writes: + +```text +motion.x = previousClip.x - currentClip.x +motion.y = currentClip.y - previousClip.y +``` + +(`MetallumNative.swift:1355-1412`). The Java mirror has the same pixel-space conversion (`MetalFxMath.java:120-155`), and the matrices passed to the V2 camera kernel are assembled from the three Java float arrays (`MetallumNative.swift:1281-1287,1928-1957`; `MetalCommandEncoder.java:457-517`). + +**Confirmed by cross-source contract:** the installed Xcode 26.5 MetalFX header says each motion value is multiplied by `motionVectorScaleX/Y` to become fragment pixels, and defines a vector as pointing from the current pixel to its previous-frame location. Its example says an object moving down/right by 10 pixels uses `(-10,-10)` (`/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX26.5.sdk/System/Library/Frameworks/MetalFX.framework/Headers/MTLFXTemporalScaler.h:266-286`; the same contract is repeated for the frame interpolator at `MTLFXFrameInterpolator.h:197-217`). Current V2 native assignment uses `inputWidth * 0.5` and `inputHeight * 0.5` (`MetallumNative.swift:1992-1996`), which converts NDC delta to input-pixel delta. Therefore the current camera-motion sign and scale are `confirmed` against both producer math and the local SDK contract; the prior report's “internal MetalFX normalization unknown” wording was too weak and is corrected by this evidence. + +**Confirmed:** depth convention matches the SDK contract. Minecraft clears depth to `0.0`, the native validity test treats `(0,1]` as valid, and the scaler is assigned `depthReversed = true` (`/tmp/minecraftmetal-mc26-sources/net/minecraft/client/renderer/LevelRenderer.java:206-212`; `MetallumNative.swift:1171-1173,1519-1524`). The SDK defines `depthReversed` as zero representing farthest distance (`MTLFXTemporalScaler.h:288-292`; `MTLFXFrameInterpolator.h:293-296`). This proves the declared convention; it does not prove every third-party shader writes the same depth encoding into the bound target. + +**Confirmed:** camera jitter is excluded from the motion projection pair but is used for depth unprojection. `currentViewProjection` is assembled before jitter; `jitteredViewProjection` is assembled after the jittered projection is applied; the inverse passed to native is the latter, while current/previous projections used for output motion are unjittered (`MetalFxManager.java:341-384`; `MetalCommandEncoder.java:300-328`). This is the intended invariant: reconstruct the world point using the projection that produced the depth, then compare unjittered screen positions. + +**Still unverified:** the Java jitter convention itself is source-confirmed but not GPU-confirmed. It uses a Halton phase, maps pixel jitter to `(2*x/width, -2*y/height)`, adds it to `m20/m21`, and passes the unmodified pixel jitter to MetalFX (`MetalFxMath.java:31-69`; `MetalFxManager.java:360-369`; `MetallumNative.swift:1513-1516`). The SDK only describes the jitter property as the pixel offset used to return to the reference frame, without a sign example (`MTLFXTemporalScaler.h:256-264`). A static camera capture must therefore still verify whether the projection injection and `jitterOffsetY` use the same sign expected by the driver. The Java unit tests prove the internal convention and the mirror formula, not the rendered sample displacement (`MetalFxMathTest.java:12-26,48-94`). + +**Matrix layout evidence:** the cached JOML 1.10.8 `Matrix4f.get(float[])` delegates to `MemUtil.copy(Matrix4fc,float[],int)`, whose bytecode stores `m00,m01,m02,m03`, then `m10...` in sequence (`/Users/retriedstormtrooper/.gradle/caches/modules-2/files-2.1/org.joml/joml/1.10.8/fc0a71dad90a2cf41d82a76156a0e700af8e4f8d/joml-1.10.8.jar`, `org.joml.Matrix4f.get(float[])`, `org.joml.MemUtil$MemUtilNIO.copy(...)`). Swift consumes each four-float group as one `simd_float4x4` column (`MetallumNative.swift:1270-1277`). This is strong static evidence for a column-grouped transfer; an on-GPU identity/known-transform capture is still the final check for the complete Java/JOML/Swift/Metal multiplication path. diff --git a/docs/render-pipeline-forensics/06-shader-and-pipeline-compilation.md b/docs/render-pipeline-forensics/06-shader-and-pipeline-compilation.md new file mode 100644 index 000000000..975c5b4e9 --- /dev/null +++ b/docs/render-pipeline-forensics/06-shader-and-pipeline-compilation.md @@ -0,0 +1,80 @@ +# Shader 与 Pipeline 编译链 + +> **2026-07-26 status:** 本文是实现前编译链快照。当前 indexed V2 ABI、1/2/3/8-slot pipeline 和 Java-to-GPU integration test 已完成；以最终验收报告中的 MRT receipt 为准。 + +## 当前实际编译链 + +```text +Minecraft/Sodium GLSL source + -> Minecraft GlslCompiler / define injection + -> shaderc GLSL -> SPIR-V + -> IntermediaryShaderModule reflection + -> MetalDevice shader cache + -> MetalCrossShaderCompiler / SPIRV-Cross + -> MSL 4.0 with binding remap + -> regex entry-point extraction + -> metallum_create_shader_function / MTLDevice.makeLibrary(source:) + -> MetalCompiledRenderPipeline + -> MTLRenderPipelineDescriptor + -> MTLRenderPipelineState +``` + +### 1.

On successful encode it may copy/seed the pre-GUI output for the conditional Frame Generation path, clears UI depth, stores previous VP, advances phase and commits the motion-state transaction (`MetalFxManager.java:499-549`).

Native direct-mask logic marks a pixel as exactly `0.0` or `1.0` when the maximum of alpha/red/green/blue is above `0.001`; the later motion kernel preserves that value and maxes it with depth-edge reactivity (`MetallumNative.swift:1098-1126,1175-1209,1211-1265`). + +## Exact reactive coverage boundary + +**Confirmed direct coverage:** the Java frame-graph pass only registers five optional color handles and reads them into the native compute pass (`MetalFxManager.java:518-566`; `MetalCommandEncoder.java:339-368`; `MetallumNative.swift:1346-1398`). The native kernel reads the same pixel coordinate from each non-null texture and writes a binary `R8_UNORM`-compatible value to `reactiveTexture` (`MetallumNative.swift:1098-1126`). The current log confirms all five handles were non-null in one successful frame (`run/logs/latest.log:108`), but that log does not prove their pixel contents were nonzero. + +**Confirmed absence of direct CUTOUT coverage:** Minecraft groups `SOLID` and `CUTOUT` together as `ChunkSectionLayerGroup.OPAQUE` and maps that group to `mainRenderTarget` (`/tmp/minecraftmetal-mc26-sources/net/minecraft/client/renderer/chunk/ChunkSectionLayerGroup.java:10-37`). Sodium's `SodiumWorldRenderer.drawChunkLayer` renders `DefaultTerrainRenderPasses.SOLID` and `.CUTOUT` in that opaque group, while only `.TRANSLUCENT` is selected for the translucent group (`/tmp/minecraftmetal-sodium-decomp/net/caffeinemc/mods/sodium/client/render/SodiumWorldRenderer.java:220-226`; `DefaultTerrainRenderPasses.java:5-9`). The Sodium terrain pass also sets `fragmentDiscard=true` for CUTOUT and `isTranslucent=false` (`TerrainRenderPass.java:10-40`). Thus leaves/grass are not read by the direct five-target mask. + +**Confirmed indirect CUTOUT handling:** after the direct mask pass, `metallum_motion_reconstruction` samples the main scene depth and examines an 8-neighbor 3x3 window. A valid/invalid depth boundary becomes reactive `1.0`; a valid-valid depth gradient becomes `clamp(gradient * 4.0, 0, 1)` (`MetallumNative.swift:1175-1209,1255-1265`). This is a depth discontinuity heuristic, not a leaf/material/alpha classification. It can mark a cutout edge, but source cannot establish its true pixel recall or false-positive rate. + +**Ordering:** the reactive frame-graph pass is added at the HEAD of `LevelRenderer.addAlwaysOnTopPass`, after the vanilla frame graph has already added main, clouds, weather, transparency-chain, and other passes (`LevelRenderer.java:184-244`; `LevelRendererMetalFxMixin.java:20-27`). It reads the current target handles and disables pass culling (`MetalFxManager.java:531-538`). This proves the pass is intentionally placed after those handle-producing passes and before the always-on-top pass is added; a GPU capture is still needed to prove the final scheduled execution order and whether any later pass changes the relevant target before Temporal encode. + +**Confidence:** direct handle set, binary threshold, CUTOUT target classification, and depth heuristic are `confirmed` by source. Actual mask pixel occupancy, alignment with the main depth/color target, and usefulness for wind/alpha coverage remain `unknown` without a texture capture/readback. + +因此： + +- direct coverage = translucent, item entities, particles, weather, clouds; +- indirect coverage = depth boundaries in main target; +- alpha-cutout leaves/grass are not direct handles; +- object transform/vertex wind motion is not represented; +- mask is binary/near-binary rather than a measured continuous material strength. + +## 当前实现成熟度分类 + +### 正确或强证据支持 + +- active modes have real scaled scene target and native-resolution output; +- Temporal has non-null depth, motion and reactive resources on the successful path; +- Halton jitter and current/previous camera reconstruction are connected; +- GUI draw is after `beforeGui` and redirected to native UI target; +- history reset has explicit frame-local reasons; +- native scaler/interpolator is cached rather than an always-new Java wrapper. + +### 近似/临时处理 + +- motion is camera/screen-space reconstruction only; +- reactive is five-target plus depth-edge heuristic; +- alpha-cutout and dynamic entity coverage is indirect; +- Frame Generation pacing samples `NSScreen.maximumFramesPerSecond` when the native presenter is created; no dynamic display-timing/VRR callback is present; +- fullscreen copy fallback is used after encode failure. + +### 仅由单测证明 + +`MetalFxMathTest` covers Halton/jitter, field-of-view extraction, static/translation/rotation motion, invalid matrix, scale/phase and mode fallback (`/Users/retriedstormtrooper/Documents/Projects/Active/MinecraftMetal/MetalUniversal-master/src/test/java/com/metallum/client/metal/render/MetalFxMathTest.java:11-158`).

GUI is post-MetalFX. +2. Depth is available at encode time on successful path; lifetime across every post/GUI branch remains runtime concern. +3. The current final motion is camera/screen-space reconstruction because object validity is cleared and no renderer writes object motion; V2 merge topology exists but object motion is not connected. +4. Jitter is applied to scene projection; current/previous projection used for motion is unjittered, but actual depth/jitter alignment needs capture. +5. Reactive sources are five transparency targets plus depth neighborhood heuristic; no direct cutout/entity velocity mask. +6. Menu/chat/HUD normal GUI are after Temporal; hand is before Temporal because it is part of `renderLevel`. +7. Temporal output can receive an extra copy/seed and then GUI before present; no additional confirmed post-GUI temporal pass exists. Frame Generation after this point is gated off by `OBJECT_MOTION_PRODUCER_CONNECTED=false` in the current source. + +## 性能与颜色限制 + +The current source proves extra color/auxiliary allocations, motion compute, reactive compute, MetalFX encode and optional fullscreen copies. It does not prove a performance win, exact color-space/alpha conversion, or whether `CAMetalLayer` drawable can be directly used by every MetalFX mode. Those require runtime counters/GPU capture and are intentionally left unknown. diff --git a/docs/render-pipeline-forensics/08-dynamic-content-and-transparency.md

MetalFX。`LevelRenderer` 在 shader transparency 下创建 `item_entity` target，并在 main pass/always-on-top pass 中读写它（`/tmp/minecraftmetal-mc26-sources/net/minecraft/client/renderer/LevelRenderer.java:190-198,365-399,490-500`）；它随后只是 reactive input，不会自动提供 velocity。 + +Falling block 和载具的实体位移有 Entity `xOld/current` 插值；车辆 passenger offset 甚至在 EntityRenderer 中单独用 partial tick 计算（`EntityRenderer.java:173-183`），但没有 motion attachment。**confidence=confirmed current-state path, confirmed missing bridge field。** + +### Block entity、活塞、方块实体动画 + +`BlockEntityRenderDispatcher` 以 partialTicks 调用 renderer `extractRenderState`，之后 submit 当前 state（`/tmp/minecraftmetal-mc26-sources/net/minecraft/client/renderer/blockentity/BlockEntityRenderDispatcher.java:76-108`）。基础 `BlockEntityRenderState` 只有 `blockPos`、`blockState`、`blockEntityType`、light 和 break overlay，没有 previous position/transform（`BlockEntityRenderState.java:17-33`）。具体 renderer 可以在自有 state 中保存动画参数；当前 MetalFxManager 不接收这些 state，因此活塞、箱子、告示牌、模组 block entity 的局部动画没有对象 motion。 + +`BlockEntityRenderDispatcher.onResourceManagerReload` 会重建 renderer map（`:111-124`），这也使 renderer-local previous state 的生命周期需要单独设计；当前没有与 MetalFX history 的连接证据。 + +### 第一人称手与持有物 + +第一人称 hand/item 由 `GameRenderer.renderLevel` 内的 scene-side path 提交：LevelRenderer world pass 后，`renderItemInHand` 使用 `cameraEntityPartialTicks`，向 hand node storage 提交 hands/items/features；之后才离开 renderLevel，进入外层 `GameRenderer.render` 的 `beforeGui` 注入点（`/tmp/minecraftmetal-mc26-sources/net/minecraft/client/renderer/GameRenderer.java:547-605`；MetalFX injection `GameRendererMetalFxMixin.java:78-84`）。`ItemInHandRenderer.submitHandsWithItems` 对 attack/view bob、hand height、use/swing animation 仍使用当前 `frameInterp`（`ItemInHandRenderer.java:346-383`）。它不是 `GuiRenderer` 的 HUD，但也没有独立 hand motion/reactive target；相机抖动和手部动画都进入同一低分辨率 scene color/depth，motion 仍是相机重建。 + +### 粒子 + +`Particle` 明确保存上一 tick `xo/yo/zo` 与 current `x/y/z`，还保存 velocity `xd/yd/zd` 和 age；tick 首先将 current 复制到 old 再移动（`/tmp/minecraftmetal-mc26-sources/net/minecraft/client/particle/Particle.java:19-40,94-115`）。`ParticleEngine.extract` 以 partialTickTime 调用每个 particle group 的 extraction（`ParticleEngine.java:128-133`），`SingleQuadParticle.extractRotatedQuad` 实际用 `Mth.lerp(partialTickTime, xo/x)` 等生成当前 quad 位置（`SingleQuadParticle.java:47-85`）。这是比 entity bridge 更明确的粒子 current/previous source，但当前 MetalFX motion shader 仍只读 scene depth/camera matrices。`LevelRenderer` 在 shader transparency 下创建/读写 `particles` target（`LevelRenderer.java:190-198,365-399`），所以 reactive direct coverage 可用；velocity replay 未接入。 + +### 雨雪、云、世界边界 + +`LevelRenderer` 将 clouds/weather 建成单独 FrameGraph passes；cloud pass 使用 cameraPosition/gameTime/partialTicks，weather pass 调用 `WeatherEffectRenderer.render`（`/tmp/minecraftmetal-mc26-sources/net/minecraft/client/renderer/LevelRenderer.java:450-488`）。`WeatherEffectRenderer.extractRenderState` 按 partial tick 生成雨雪 columns，render 使用 weather target（`WeatherEffectRenderer.java:66-98,119-145`）；CloudRenderer 根据 gameTime、partialTicks 和 camera position 计算 cloud offset，并按 cell/camera 状态重建 mesh（`CloudRenderer.java:149-207`）。对应 targets 是 `targets.clouds` 与 `targets.weather`（`LevelRenderer.java:190-198,450-488`），并由 manager reactive pass 读取。它们没有对象 previous transform 传给

an exact routing fact that matters for motion coverage: `SodiumWorldRenderer.drawChunkLayer` sends the Minecraft `OPAQUE` group to the SOLID and CUTOUT terrain passes, and sends the `TRANSLUCENT` group only to the TRANSLUCENT terrain pass (`/tmp/minecraftmetal-sodium-decomp/net/caffeinemc/mods/sodium/client/render/SodiumWorldRenderer.java:220-226`). `DefaultTerrainRenderPasses` defines CUTOUT as non-translucent but fragment-discard capable, while TRANSLUCENT is both translucent and discard capable (`DefaultTerrainRenderPasses.java:5-9`; `TerrainRenderPass.java:10-40`). The target selection maps non-translucent terrain to `GameRenderer.mainRenderTarget()` and translucent terrain to `LevelRenderer.translucentTarget()` when shader transparency is enabled (`TerrainRenderPass.java:36-40`). + +This makes the existing artifact boundary concrete: + +- CUTOUT leaves/grass are in the main color/depth path and are not among the five direct reactive inputs. +- Terrain translucent water/glass can reach the direct `translucent` target when the transparency chain is active. +- Entity cutout/translucent classification is renderer-specific; the five target names alone do not prove every entity feature is routed to `itemEntity` or `translucent`. +- Sodium's `ChunkSectionsToRenderMixin` cancels vanilla `renderGroup` and calls `SodiumWorldRenderer.drawChunkLayer` when its renderer is installed (`/tmp/minecraftmetal-sodium-decomp/net/caffeinemc/mods/sodium/mixin/core/render/world/ChunkSectionsToRenderMixin.java:28-37`). Therefore the CUTOUT routing above is the actual Sodium path, not just a theoretical vanilla fallback. + +**Confidence:** CUTOUT versus TRANSLUCENT routing is `confirmed` for the inspected Sodium 0.9 artifact. Full modded entity/particle routing and actual per-pixel output still require runtime pipeline/target enumeration. + +## 后续验证所需的最小证据 + +- runtime capture 标出实体、粒子、cutout、translucent 的 bound color/depth target 和 pipeline key； +- 对同一相机的静止实体、平移实体、风动 cutout、粒子、透明水各录两帧，比较 motion/reactive 实际纹理； +- 记录 partial tick、current render state 和 GPU pass 的时间关系； +- 验证第三方 renderer 是否经过 `EntityRenderer`/`MetalCrossShaderCompiler`，不要由 vanilla path 推断模组兼容性。 diff --git a/docs/render-pipeline-forensics/09-known-artifacts-root-cause-map.md

做跨层相等断言，export scalar 主要用于日志。**confidence：native source path=confirmed；当前运行时尺寸相等=needs runtime log/capture。** + +在 `beforeGuiInternal`，Temporal/Spatial 输出首先写入 `sceneOutputTarget`（FG 开启时）或 `uiTarget`；FG 开启时再把该 scene output copy 到 `uiTarget`，随后 GUI 在 `uiTarget` 上绘制（`MetalFxManager.java:421-475`）。因此 FG 的 scene color 是 pre-GUI，ui color 是 post-GUI；两者不是同一张 history texture。 + +`MetalCommandEncoder.presentTextureToDrawable` 在最终提交前调用上述输入函数；若 dormant gate 未来打开且 native encode 成功，才会调用 `metallum_metalfx_frame_generation_encode`，否则回到普通 `encodePresentTextureToDrawable`（`MetalCommandEncoder.java:349-389`；bridge 包装在 `MetalNativeBridge.java:1001-1050`；Swift export 在 `MetallumNative.swift:2013-2095`）。 + +**置信度：confirmed control

取出后等待 event；等待失败或输入 command buffer 失败时直接 `completeFrame()`，不会继续调用 `presentRealFrame`（`:623-635`、`:555-577`）。这是“丢弃整个 source frame”路径，不只是跳过插值。 + +`process` 先选 `previousIndex = lastEncodedIndex ?? frame.index`，并以 `frame.reset || lastEncodedIndex == nil` 决定 interpolator reset。首帧因此 current/previous color 是同一 slot 且 reset 为 true。成功编码并 commit 插值 command buffer 后才更新 `lastEncodedIndex` 和 `lastEncodedTimestamp`，随后调用 `presentRealFrame`（`MetallumNative.swift:637-697`）。 + +插值器实际绑定：当前 scene color、上一 accepted scene color、当前 depth、当前 motion、当前 composed UI；`isUITextureComposited=true`，jitter/FOV/near/far/aspect/deltaTime/depthReversed/reset 逐字段设置（`:657-681`）。UI 没有单独的 previous UI slot；`prevColorTexture` 是 scene history。 + +真实帧在同一个 native `presentQueue` 上排在插值 command buffer 后面，源为 `composedBuffers[index]`，`present` 使用 `afterMinimumDuration: frameDuration * 0.5`（`:699-728`）。源码顺序足以确认“插值 present command 先提交、真实 present command 后提交”；不能仅凭源码证明 WindowServer 最终扫描顺序在所有 GPU/显示器条件下都严格保持该间隔。 + +## 时间参数与刷新率 + +`frameDuration` 不是固定 120 Hz。presenter 初始化时从 layer delegate 的 window screen 或 `NSScreen.main` 读取 `maximumFramesPerSecond`，下限 30、缺失时默认 60，再计算 `1.0 / refreshRate`（`MetallumNative.swift:149-170`）。它只在 presenter 创建时采样；源码没有更新屏幕切换、VRR 状态或显示器刷新率变化的回调。 + +`PendingFrame.timestamp` 在 render thread enqueue 时用 `CACurrentMediaTime()` 记录（`:468-474`）。`process` 使用上一 accepted interpolation timestamp 计算 `deltaTime`，并 clamp 到 `[1/240, 0.25]`；reset/首帧/非有限或非正 delta 使用 `frameDuration`（`:637-648`）。所以： + +- 真实 frame 间隔由 `afterMinimumDuration(frameDuration * 0.5)` 约束，不是 CPU sleep； +- 插值器 delta time 主要来自 enqueue timestamp，不是 drawable presentation timestamp； +- VRR、显示器实际刷新、WindowServer queue latency 和 scanout 没有源码证据； +- presenter 创建后刷新率改变不会自动更新 `frameDuration`。 + +**置信度：前两项和采样逻辑 confirmed；非 30/60/120 Hz 的最终行为为 strong_inference risk，VRR 行为 unknown。** + +## drop、resize、GUI、shutdown + +- `layer.maximumDrawableCount=3`、`allowsNextDrawableTimeout=true`。`nextDrawable()` 返回 nil 时，插值阶段会退化到 `presentRealFrame`；真实阶段拿不到 drawable/command buffer 时只 `completeFrame`，没有进一步 CPU fallback（`MetallumNative.swift:166-170,650-703`）。实际 timeout 长度未知。 +- 输入 command buffer error 会把 event value 直接推进到失败值并登记 `failedInputEvents`，worker 随后丢弃该 frame，避免一秒等待卡住（`:555-577`）。 +- source 尺寸、格式或 layer pixel format 改变时，`encode` 调 `resizeResources`；该函数先 `drain()`，再创建 texture set、新 interpolator 和 copy pipeline，最后清空 `nextBufferIndex`、`lastEncodedIndex`、`lastEncodedTimestamp`（`:443-457,375-417`）。 +- `drain` 等待 `outstandingFrames==0`；`shutdown` 设置 `stopping`、唤醒 worker，并等待 `workerExited` 与 `outstandingFrames==0`，之后 native stop 函数把 presenter 置空，下一次 encode 懒创建（`:738-762`；export `MetallumNative.swift:1715-1742`）。 +- 若后续打开 FG gate，GUI screen/overlay active 时，Java `frameGenerationInputInternal` 会调 `suspendFrameGenerationForGuiInternal`；它停止 native presenter 但保留 `sceneOutputTarget`，最终走普通单 present。GUI 消失后的下一帧重新开启 FG 并 reset Temporal history（`MetalFxManager.java:289-301,790-842`）。当前 gate 为 false，因此这段 pause/resume 逻辑未被当前 Java 配置实际触发。 + +## 当前不能静态确认的事项 + +1.

The normal `MetalDevice.close` caller does call `waitForSubmittedGpuWork()` first, and that method waits for the latest submit (`MetalDevice.java:178-190`; `MetalCommandEncoder.java:799-809`). Therefore the ordinary device-close sequence has a Java GPU wait, while a direct encoder close would not. This does not prove every target destruction path is ordered after that wait. + +## Native resource/sync facts + +- Native texture descriptors use `.private` for MetalFX texture sets (`MetallumNative.swift:245-323`) and one general texture creation path sets `hazardTrackingMode = .untracked` (`:2346-2373`). Untracked resources require the command/event ordering to be correct; no implicit hazard tracking can be assumed. +- Frame Generation has one `readyEvent`, condition variables, `maxOutstandingFrames=1`, one-second ready wait/drop, and explicit event signaling for failed buffers (`MetallumNative.swift:78-125,419-577,623-762`). There is no separate pacing shared event or pacing worker in the current source. +- Native resize/shutdown drains outstanding frames, rebuilds slot textures, stops/joins the worker (`MetallumNative.swift:375-417,738-762,2147-2177`). Native resize is entered from `MetalFrameGenerationPresenter.encode` when input dimensions/formats or layer pixel format differ (`:443-457`); the exact Java call that causes this native resize for every surface/fullscreen/Retina path is not established. Since the current Java FG gate is false, this is conditional rather than observed current-frame behavior. +- Native `metallum_release_object` uses retained-pointer release (`MetallumNative.swift:3064-3070`); Java wrappers therefore cannot assume ARC release occurs at Java GC time. + +## Thread model + +| State | Owner thread | Shared with | Synchronization evidence | +| --- | --- | --- | --- | +| Minecraft camera/projection/history | render thread | native call arguments only | Java call is synchronous; no Java lock around every manager field shown | +| Java command encoder/current pass | render thread | GPU | Metal command buffer/semaphore/fence and in-flight array | +| native scaler/pipeline cache | native invocation/render command path | native workers for FG only where applicable | Swift state/condition/event; full lock coverage not reconstructed | +| FG slots and request queue | render thread enqueue + `MetalFX PresentThread` | render thread enqueue | condition variable + `readyEvent`, `maxOutstandingFrames=1` | +| CAMetalLayer drawable | native present worker or render thread | Window system | Java configure sets `drawableSize`, `displaySyncEnabled`, and macOS timeout policy; FG presenter overrides `allowsNextDrawableTimeout` to true (`MetallumNative.swift:2968-2999,166-170`) | + +## Safety conclusions + +1. **Confirmed:** normal Java resource destruction is deferred through submit/fence machinery for resources queued via `MetalCommandEncoder.queueForDestroy`. +2. **Confirmed:** native FG has explicit event/worker drain logic and timeout/drop behavior. +3. **Confirmed:** world/reset/FOV/invalid matrix history resets exist. +4. **Unknown:** whether every resize/fullscreen/Retina path drains both Java in-flight commands and native FG slots before destroying old targets. +5. **Confirmed sequence, unresolved cross-layer risk:** Minecraft calls `GameRenderer.close` before `RenderSystem.shutdownRenderer`; the mixin closes MetalFX auxiliary targets/native caches at `GameRenderer.close` TAIL, while `MetalDevice.close` performs its Java GPU wait later (`/tmp/minecraftmetal-mc26-sources/net/minecraft/client/Minecraft.java:1112-1137`; `GameRendererMetalFxMixin.java:104-107`; `MetalFxManager.java:694-705`; `MetalDevice.java:178-190`). Native FG shutdown drains its own presenter, but no evidence shows the Java command buffer has completed before `uiTarget`/auxiliary target destruction. This is a **strong-inference resource-order risk**, not a confirmed use-after-free. +6. **Risk:** `MetalSurface.close()` is empty (`MetalSurface.java:71-73`), so layer ownership/teardown is external; `MetalDevice.close` later clears the Cocoa layer and releases the device, but no runtime teardown trace was captured. +7. **Risk:** native texture sets are `.private`, and the general native texture path can use `.untracked`; cross-layer GPU completion must be captured before changing MRT/target lifetime. +8. **Confirmed scaffold boundary:** V2 camera/disocclusion/merge kernels and object motion textures exist, but `MetalMotionStateStore.observe` has no production caller and `prepareMotionInputs` only clears object motion/validity. The current final motion therefore falls back to camera motion; this is a missing producer, not a proven synchronization failure. +9. **Future接入 risk:** `MetalFxManager.beginFrame()` is called from the `render` HEAD injection and again inside the projection `ModifyArg` path. A future object-state observer inserted between those points could have its pending state cleared by the second transaction start; current source has no observer there, so present impact is unknown. +

+`GameRendererMetalFxMixin` 对 `GameRenderer.render` 中的所有目标字段读取做 `FIELD` redirect（`GameRendererMetalFxMixin.java:34-48`），不是以 field read 的 ordinal/local context 区分。`MinecraftMetalFxMixin` 对 `` 中的 `RenderTarget.width/height` 同样是宽作用域（`:13-27`）。这能解释为什么尺寸传播必须用 runtime capture 验证：一个 redirect 可能影响 comparison、GUI/scissor、post effect 或其它同方法 target，而不是只影响 MetalFX main target。 + +### 通用 `RenderTarget.resize(II)` redirect + +`GameRendererMetalFxMixin.java:25-32` 对 `GameRenderer.resize` 中的 `RenderTarget.resize(II)` 做 redirect，没有 `ordinal`。当前映射的 `GameRenderer.resize` 至少 resize main target 和 LevelRenderer（`/tmp/minecraftmetal-mc26-sources/net/minecraft/client/renderer/GameRenderer.java:317-320`）；如果未来同方法增加更多 RenderTarget，redirect 作用域可能扩大。历史 scissor crash 证明这类尺寸边界不是理论问题。 + +### Projection `ModifyArg` + +`renderLevel` 的 `ProjectionMatrixBuffer.getBuffer(Matrix4f)` 被 `ModifyArg(index=0)` 替换（`GameRendererMetalFxMixin.java:59-75`）。没有 locals capture，优点是局部布局变化影响较小；风险是只要同一方法出现多个相同 invoke 或 Mojang 改调用顺序，注入点可能命中错误 projection。当前没有 ordinal，因此后续版本必须重新确认 target 数量。 + +该注入还有一个当前 manager 生命周期耦合：`render` HEAD 的 `GameRendererMetalFxMixin.metallum$beginFrame` 先调用 `MetalFxManager.beginFrame()`，随后 projection `ModifyArg` 进入 `prepareSceneProjectionInternal`，后者再次调用 `beginFrameInternal`（`GameRendererMetalFxMixin.java:50-75`; `MetalFxManager.java:153-169,289-310`）。当前没有生产 `MetalMotionStateStore.observe`，所以尚未证明实际帧数据被清掉；未来若在两处之间采集对象状态，第二次 begin 会清空 pending transaction。**confidence=confirmed call topology; future data-loss impact=unknown.** + +### GUI 与 always-on-top 注入 + +GUI redirect 是 `GuiRenderer.draw` 内具体 `GameRenderer.mainRenderTarget()` invoke，作用域比 `GameRenderer` field redirect 窄（`GuiRendererMetalFxMixin.java:12-22`）。Reactive injection 在 `addAlwaysOnTopPass` HEAD，但它使用 FrameGraph `targets` handles；若 Minecraft 改变 target lifecycle或把 cutout/feature submit移到另一个 pass，mask可能缺内容。没有 capture 证明该 injection 覆盖所有透明内容。 + +## Sodium 叠加与绕行 + +Sodium 0.9 在当前解包源码中将 draw backend 选为 `VK_INDIRECT`，`DrawContext.create` 在该 backend 创建 `VKIndirectContext`；MetalUniversal 用 `MetalDrawContext extends VKIndirectContext` 接管 context（`/Users/retriedstormtrooper/Documents/Projects/Active/MinecraftMetal/MetalUniversal-master/src/main/java/com/metallum/client/metal/render/MetalDrawContext.java:13`；`/tmp/minecraftmetal-sodium-decomp/.../DrawBackend.java:8-23`、`DrawContext.java:9-23`）。`ChunkSectionsToRenderMixin.renderGroup` 又取消 vanilla group draw，改走 `SodiumWorldRenderer.drawChunkLayer`。因此： + +- Sodium terrain SOLID/CUTOUT/TRANSLUCENT 共享 Metal backend；当前 terrain pipeline 只声明一个 color target，indexed attachment backend 能力本身已存在； +- Sodium 自身 `GameRenderer`/window workaround Mixins 可能同时重定向 resize/minimized state； +- entity/block entity/particle 不会因为 Sodium terrain backend 而自动获得 motion MRT； +- 第三方 renderer 如果绕过 Mojang `RenderPipeline` 或另建 native path，当前 MetalFX mask/motion 不会自动覆盖。 + +## 无 Sodium、iOS 与其它环境 + +- 无 Sodium：config plugin 对 Sodium mixins 有条件筛选，render mixins 理论上仍可成立；但 `GameRenderer`/`LevelRenderer` 的 transparency target是否存在、`useShaderTransparency` 返回值和非-Sodium pipeline集必须单独验证。 +- iOS：native/Java mode gating 对 iOS 返回 OFF（`MetalFxManager.java:231-233`），且 `MetallumMixinConfigPlugin.shouldApplyMixin`

+- 其它渲染 Mod：当前没有 mixin priority 或冲突处理证据。`defaultRequire=1` 意味着 target 变化通常是硬失败，不是静默降级。 + +## 版本耦合等级 + +| 耦合项 | 当前状态 | 等级 | +| --- | --- | --- | +| Minecraft 26.2 mapped names/signatures | 已按当前

GUI 激活时 Frame Generation 是暂停/恢复，不是单向 disable + +**冲突：** 早期报告文本把 GUI/overlay 路径写成调用 `disableFrameGenerationInternal`、销毁 `sceneOutputTarget`，并据此推断关闭菜单后没有恢复路径。当前工作树实际由 `frameGenerationInputInternal` 调用 `suspendFrameGenerationForGuiInternal`（`MetalFxManager.java:707-715,748-760`）；该函数只停止 native presenter 并保留 `sceneOutputTarget`。下一帧 `beginFrameInternal` 在 GUI 消失后设置 `frameGenerationEnabled=true` 并调用 `resetHistoryInternal("GUI closed; frame generation resumed")`（`MetalFxManager.java:273-283`）。永久 disable 是另一条 `disableFrameGenerationInternal` 路径，会销毁 `sceneOutputTarget`（`MetalFxManager.java:671-684`）。 + +**判定：** 以后以当前源码为准：GUI 是 Java 侧 pause/resume；`stop_frame_generation` 的 shutdown 会等待 worker/outstanding-frame 状态，下一次 native encode 在 presenter 为空时懒创建新 presenter（`MetallumNative.swift:746-762,1581-1625,1715-1742`）。因此 Java/native 控制流和 drain/recreate 结构已确认，但真实 drawable timing、视觉输出和设备级完成关系仍需要运行验证。**置信度：confirmed control flow/topology; runtime output unknown。** + +## 12. JOML 到 Swift simd 矩阵链曾被错误地标成不存在 + +**冲突：** 早期 `05-matrices-jitter-motion-conventions.md` 文本把矩阵描述成只在 Java 侧使用，并声称 bridge 没有 JOML -> Swift 转换。当前工作树实际中，`MetalCommandEncoder.encodeMetalFx` 把三组 JOML `Matrix4f` 写入 float arrays（`MetalCommandEncoder.java:293-335`），`MetalNativeBridge.metallum_metalfx_encode` 复制到 native scratch segments（`MetalNativeBridge.java:803-835`），Swift `makeMatrix` 再组装 `simd_float4x4`，供 `metallum_motion_reconstruction` 使用（`MetallumNative.swift:1270-1277,1473-1493`）。 + +**判定：** Temporal motion 的 JOML -> float buffer -> Swift simd 链已确认；只有 Frame Generation 的 `FrameGenerationInput` 不携带 VP，而是携带 texture handles 和标量参数。报告和 handoff 已按当前源码更正。**置信度：confirmed data path；JOML/Swift 数学语义仍需 GPU capture 验证。** + +## 13. Java `MetalFxMath.reconstructMotion` 不是运行时 motion producer + +**冲突：** 早期章节把 `MetalFxMath.reconstructMotion` 写成当前每帧 motion producer，并只描述 legacy `metallum_motion_reconstruction`。当前源码的 manager 走 `encodeMetalFxV2`（`MetalFxManager.java:456-479`）；V2 native export 依次执行 camera kernel、object/camera merge 和 Temporal scaler（`MetallumNative.swift:1355-1475,1844-2011`）。Java helper 和 `MetalMotionContract.projectVertex` 仍没有生产调用，只有测试/定义路径（`MetalMotionStateStore.java:31-44`; `MetalMotionContract.java:64-98`; `MetalFxMathTest.java:77-169`）。 + +**判定：** 运行时 final motion producer 以 V2 native MSL 为准；由于 `prepareMotionInputs` 只清零 object motion/validity 且没有 renderer producer，V2 merge 当前选 camera motion。Java helper 只能证明 mirror/候选对象数学，不单独证明 GPU object motion texture 内容。**置信度：confirmed call topology and missing producer; actual GPU output still requires capture.** + +## 14. motion scale 曾被过度保留为未知 + +**冲突：** 早期报告只引用日志中的 `motionVectorScale=(572,321)`，因此把 MetalFX 对 motion 单位的解释保留为 unknown。当前进一步核对了本地 Xcode 26.5 SDK：`MTLFXTemporalScaler.h` 明确规定 scale 将 motion texture 值乘为 fragment pixels，并规定向右/向下移动 10 像素的 current-to-previous vector 为 `(-10,-10)`（`/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX26.5.sdk/System/Library/Frameworks/MetalFX.framework/Headers/MTLFXTemporalScaler.h:266-286`）。native producer 输出 NDC 差值，随后设置 `inputWidth * 0.5` / `inputHeight * 0.5`（`MetallumNative.swift:1211-1265,1517-1522`）。 + +**判定：** 当前 V2 motion 的方向和像素 scale 与已安装 SDK 契约一致，属于 `confirmed`；V2 camera/merge 都在 `MetallumNative.swift:1844-2011` 设置 `inputWidth * 0.5` / `inputHeight * 0.5`。仍未知的是驱动实际采样后的画面结果、jitter 的最终符号响应和动态对象覆盖，不是 scale 公式本身。第 05、07、09、00 章与 handoff 已更新。**置信度：confirmed contract; GPU output unknown。** + +## 15. Frame Generation 刷新率与 worker 数量曾被写错 + +**冲突：** 旧摘要和多个章节把 Frame Generation 描述成固定 `1/120`、`realFramePaceFraction=31/64`、两个 worker、两个 shared event、最多两个 outstanding frame。当前 `MetallumNative.swift` 中没有这些符号：`rg` 只找到一个 `readyEvent`、一个 `MetalFX PresentThread`、`bufferCount=3` 和 `maxOutstandingFrames=1`（`src/main/native/MetallumNative.swift:78-125,188-194`）。`frameDuration` 实际在 presenter 初始化时按 `NSScreen.maximumFramesPerSecond` 采样，缺省 60、下限 30（`:149-170`）；真实 present 使用 `afterMinimumDuration: frameDuration * 0.5`（`:699-728`）。 + +**判定：** 以当前 Swift 源码为准：不是固定 120 Hz，也没有独立 Frame Pacing worker/pacing shared event；存在一个 render-thread enqueue + 一个 `MetalFX PresentThread` worker 和一个 ready shared event。旧的固定 120/双 worker/双 event 描述已降级为 stale 文本。**置信度：confirmed source correction；限制：实际 WindowServer/VRR present timing 仍未知。** + +## 16. Frame Generation native export 行号和失败语义曾被过度扩大 + +**冲突：** 旧章节把 `metallum_metalfx_frame_generation_encode` 引用为旧行号，并把 `readyEvent` timeout 写成只丢插值帧。当前 export 是 `MetallumNative.swift:2013-2095`；Java bridge/present caller 是 `MetalCommandEncoder.java:349-389` 和 `MetalNativeBridge.java:1001-1050`。worker `process` 仍在 `MetallumNative.swift:623-728`；ready event 一秒等待失败或 `failedInputEvents` 命中时直接 `completeFrame()` 返回，不调用 `presentRealFrame`，因此可以丢弃整个 source frame。只有 `nextDrawable`/插值 command 创建失败时才进入 `presentRealFrame` 退化路径。 + +**判定：** 以后使用 `10-frame-generation-and-presentation.md` 的窄行号；把 event timeout 描述为“source frame 被丢弃”，不能描述为“必然保留真实帧”。另外，当前 `MetalFxManager.java:29-33,99-116` 把 FG gate 固定为关闭，所以以上是 dormant conditional topology，当前运行没有 worker present 证据。**置信度：confirmed control flow and gate; device drop frequency unknown.** + +## 17. MRT 边界曾被错误地写成 native 单附件限制 + +**冲突：** 旧报告把 `MetalCommandEncoder.createRenderPass`、`MetalRenderPass`、`MetalCompiledRenderPipeline` 和 Swift native descriptor/encoder 描述成只消费 `color attachment 0`，并据此把通用 backend 标成无法绑定 MRT。当前工作树的窄读与 Minecraft 26.2 mapped source 直接反证该表述：`RenderPipeline.Builder` 保留 8 个 color slots，`RenderPass.setPipeline` 按数量校验；Java encoder 逐槽建立 `MemorySegment[]` 并调用 `makeRenderCommandEncoderV2`；`MetalRenderPass` 保存 `GpuTextureView[]`；PSO 逐槽设置 format/blend；Swift v2 render pass 与 descriptor setters 都按 index 支持 0..<8（`/tmp/minecraftmetal-mc26-sources/com/mojang/blaze3d/pipeline/RenderPipeline.java:147-159,241-255`；`/tmp/minecraftmetal-mc26-sources/com/mojang/blaze3d/systems/RenderPass.java:82-98`；`MetalCommandEncoder.java:134-180,205-227`；`MetalRenderPass.java:33-80,382-409`；`MetalCompiledRenderPipeline.java:114-125,187-216`；`MetallumNative.swift:2484-2580,3214-3275`）。 + +**判定：** 以当前源码为准：通用 backend 的 indexed MRT binding capacity 已确认；当前已枚举 Minecraft 26.2 `RenderPipelines` 和 Sodium 0.9 `ShaderChunkRenderer` 仍只声明 slot 0，fragment output 是否在所有运行时/第三方 shader 中产生第二个 color location 尚未完整枚举。因此后续报告把“native 单附件”降级为 stale，把“当前 motion MRT contract 缺失”保留为 confirmed inspected-source boundary。**限制：** 没有 runtime pipeline log 或 GPU capture，不能把静态枚举推广成所有第三方 pipeline。 + +## 18. indexed MRT 源码、bundled dylib 与实际加载库不是同一证据 + +**事实：** 当前 Swift 源码和 Java bridge 都提供 v2/indexed symbols；对工作树现有二进制执行 `nm -gU` 也能看到 macOS 与 iOS `libmetallum.dylib` 中的 `metallum_MTLCommandBuffer_makeRenderCommandEncoder_v2`、`metallum_MTLRenderPipelineDescriptor_setColorAttachmentFormat` 和 `...setColorAttachmentBlendState`。这是对 bundled artifacts 的静态交叉证据。Java bridge 的 `optionalDowncall` 允许 symbol 缺失；缺失时单附件使用 legacy path，多附件 render encoder、非零 attachment format/blend 会抛出 `IllegalStateException`（`MetalNativeBridge.java:696-700,1341-1371,1820-1842,1861-1890`）。 + +**判定：** 当前报告可以确认“源码 + 当前 bundled dylib 具备 indexed MRT symbols”，但不能仅凭 `nm` 证明 Minecraft 进程实际加载的是这两个 bundled 文件；macOS/iOS loader 还有 `System.loadLibrary`、Frameworks 和 iOS temporary extraction 分支（`MetalNativeBridge.java:529-568`）。因此 active loaded dylib、实际 `SymbolLookup` 结果和运行时多附件 render pass 仍标为 unknown/需要运行验证。此前 build task 可能重写 bundled dylib 的风险仍独立保留在第 5 节。 + +## 19. Frame Generation 的 Java input scalar 与 native texture 尺寸有两套来源 + +**事实：** `MetalFxManager.frameGenerationInputInternal` 把 `renderWidth/renderHeight` 放入 `FrameGenerationInput`（`MetalFxManager.java:790-822`），Java export 也接收这两个参数；但 Swift `metallum_metalfx_frame_generation_encode` 创建 `PendingFrame` 时从实际 `depth.width/height` 写入 input dimensions，`makeFrameInterpolator` 同样用 depth dimensions 作为 input、scene color dimensions 作为 output，motion scale 从 native frame input dimensions计算（`MetallumNative.swift:2013-2095,204-221,528-547,667-679`）。 + +**判定：** 当前目标资源设计应使两者相等，因为 main depth/motion 是 render size，scene output 是 display/native size；但没有跨层 assert 或 runtime log 同时打印 Java scalar 与 depth texture dimensions。若两者分离，Java 日志和 native interpolator scale 可能描述不同输入尺寸。**置信度：producer/consumer source path=confirmed；实际运行时 equality=unknown，需要 resize/Retina/odd-size capture。** + +## 20. V2 object motion 是资源/merge scaffold，不是已接入对象 producer + +**事实：** 当前 `MetalFxManager.ensureAuxiliaryTextures` 创建 `cameraMotionTexture`、`objectMotionTexture`、`objectValidityTexture`、`disocclusionTexture`、`motionTexture` 和 `reactiveTexture`；`prepareMotionInputs` 只调用 `clearMotionInputs(objectMotionTexture, objectValidityTexture, ...)`（`MetalFxManager.java:642-700`; `MetalCommandEncoder.java:391-408`）。native V2 camera kernel 写 camera/disocclusion，merge kernel 仅当 validity > 0.5 时选择 object motion（`MetallumNative.swift:1355-1475`）。 + +**交叉核验：** Java `MetalMotionStateStore.observe` 只有定义，`rg -n "observe\\(" src/main/java` 没有生产 caller；`MetalMotionContract.projectVertex` 的调用只出现在 `MetalFxMathTest`。`EntityRenderer`、`Particle` 等旧/current state 证据因此不能被升级成 MetalFX object motion producer。 + +**判定：** 当前 final motion 的静态/相机部分是 connected；object motion/velocity replay 未接入。**置信度：confirmed source boundary；实际 attachment 全帧值仍需 GPU capture。** + +## 21. Frame Generation gate 与 native presenter 是两种状态 + +**事实：** `OBJECT_MOTION_PRODUCER_CONNECTED` 在当前 Java source 固定为 `false`，`frameGenerationEnabled` 初始化要求它为真（`MetalFxManager.java:29-33,99-116`）。native presenter、slots、worker、shared event 和 export 仍存在（`MetallumNative.swift:65-221,2013-2095`），但 `frameGenerationInputInternal` 只有 gate 打开才返回输入（`MetalFxManager.java:790-822`）。 + +**判定：** 报告可以描述 Frame Generation 的控制流和潜在 pacing，但不能把它描述成当前每帧真实 present。需要运行验证的是 active gate、loaded symbols、实际 queued frame 和 drawable timestamps；静态 native worker 代码不等于已经启动 worker。**置信度：Java gate=confirmed；current runtime worker activation=needs runtime verification.** + +## 22. V2 symbols 与构建副作用的边界 + +**事实：** Swift source 有 `metallum_metalfx_supports_motion_v2`、`metallum_metalfx_clear_motion_inputs` 和 `metallum_metalfx_encode_v2`（`MetallumNative.swift:1559-1615,1844-2011`）；对现有 macOS/iOS bundled dylib 的精确 `nm -gU` 查询也分别看到这三个 symbols。该结果比只查 indexed render symbols 更完整。当前 bundled artifact 与 source 的 symbol presence 已静态对齐。 + +**限制：** `MetalNativeBridge.createSymbolLookup` 仍有系统库、Frameworks 和临时 extraction 分支，`nm` 不能证明游戏进程实际加载哪一个文件（`MetalNativeBridge.java:529-568`）。同时 `build.gradle:53-74,109-132` 直接把 native build 输出写入 `src/main/resources/natives/{macos,ios}/libmetallum.dylib`；没有 Git 基线、构建前 SHA 或 capture，不能声称 build 前后 bytes 未变，也不把该二进制副作用描述成源码实现修改。**置信度：source/bundled symbol presence=confirmed；active loader identity and byte delta=unknown.** diff --git a/docs/render-pipeline-forensics/sol-handoff.json b/docs/render-pipeline-forensics/sol-handoff.json new file mode 100644

existing sodium mixins compile+runtime verified; real-client smoke A: Metal backend, ~4min in-world, clean log - Iris 1.11.2+26.2-fabric added to the dev classpath (loads as a mod) - Dormancy shim set (com.metallum.mixin.iris.*, gated on Iris present + default backend, live-backend checked at runtime): cancels Iris's GL entry points (RenderSystem-init chain, GLDebug incl. runtime push/pop/name, IrisRenderSystem.initRenderer/supportsSSBO, IrisSamplers.initRenderer, VanillaRenderingPipeline clip-control, loadShaderpack); GlStateManager._getInteger answers conservative constants during dormant clinit probes; MetalGpuTexture overrides the mixin-injected iris$getGlId with synthetic ids for Iris's per-texture tracking hook - MetalFxManager.reactiveTexture gains RENDER_ATTACHMENT usage (deferred clear materializes it as a color target; Metal validation aborted) - Validation docs: smoke A/B1-B7 evidence, vanilla 26.2 startedCleanly crash-fallback mechanism (forces OpenGL after startup crash), harness discipline; acceptance report: Phase 1 FAIL (8/12 gates), Phase 2 not started per spec ordering Verified: smoke B7 (Metal + Sodium 0.9.1 + Iris dormant) 28s to world, 90s sustained in-world rendering, 0 crash markers; regression green: test + MRT 14/14 + compute 10/10 + iris-targets 6/6.

docs/iris-audit/b2-1-design-handoff.md(活文档,S4/S6 有可直接照做的实现规格)。 编译线(已验证): - MetalIrisShaderCompiler 新增 translateSodiumTerrain/linkPatchedPair: TransformPatcher.patchSodium → 松散 uniform 收进 std140 MetallumIrisUniforms 块(两 stage 注入同一份块文本,避免同一 binding 上布局不一致)→ 出 GLSL, 由库存链(vanilla GlslCompiler → IntermediaryShaderModule.rebind → SPIRV-Cross) 接手。std140 偏移表在测试里对着 SPIRV-Cross 反射逐项校验,不靠推断。 - IrisMetalPipelineOverrides:按 IrisPipelines.getPipeline 的字节码判定 sodium 管线的 solid/cutout/translucent,懒构建合成 RenderPipeline(XHFP 顶点格式、 DRAWBUFFERS 决定的 colorTargets、sodium 自身 BindGroupLayout 逐字复制 + 只追加包新增的名字)。全链失败一律 fail-open 回落原生编译。 - MetalDevice 两处 computeIfAbsent 前置查询覆盖注册表。 MetalCrossShaderCompiler:按槽宽重排 varying location(根因修复)。 库存链给 stage 接口变量分配 location 是“一个变量一个槽”,不计类型占用; 光影包的矩阵 varying(Potato 的 out mat2 / flat out mat4x3)按列各占一个槽, 于是后面的变量落进前一个的区间,MSL 出现重复 [[user(locnN)]],MTLLibrary 编译 失败。新增 varyingLocationSpans(SPIRV-Cross 反射算槽宽)+ relocateVertexOutputs /relocateFragmentInputs,两侧按同一起始 location 紧密重排;未连接的 fragment 输入排到 vertex 输出区之后并告警一次。原版路径 varying 全是标量/向量,重排结果 与原编号等价。 唤醒线(编译通过,未做游戏内验证,默认关): - MetalIrisCompat.semanticLayerEnabled() / -Dmetallum.iris.semantic - loadShaderpack 放行;Iris.createPipeline 重定向到 MetalWorldRenderingPipeline (extends VanillaRenderingPipeline,镜像 WorldRenderingSettings 置位含 XHFP 顶点格式;失败回落 VanillaRenderingPipeline,绝不放行 GL 构造器) - StandardMacros 的 GL 面假接成与离线矩阵同款的 pinned GL 4.6 环境 默认关的原因:S4(uniform 供给)与 S6(pass 资源预置)未做,开了会在首次地形 绘制抛 Missing uniform MetallumIrisUniforms。 验证:metalIrisShaderTranslationTest 全绿(B2-2 矩阵 + B2-1 terrain, BSL/Potato × solid/cutout/translucent 6/6 PSO 有效);回归 test / metalMrtBackendIntegrationTest / metalComputeBackendIntegrationTest / metalIrisTargetsIntegrationTest 全绿。 阶段一验收维持不通过:真实渲染验证未做。 Co-Authored-By: Claude Fable 5 --- build.gradle | 1 + docs/iris-audit/b2-1-design-handoff.md | 219 +++++++++

    2. activates {@link IrisMetalPipelineOverrides}, so sodium's terrain + * pipelines compile from the pack's translated programs.

Follow-up (2026-07-27b): sky far-plane motion + full reactive-writer audit + +In-game testing after §12a confirmed leaves stopped shimmering but geometry +silhouetted **against the sky** (tree tops, vines) still strobed. Root cause: +sky pixels (cleared reversed-Z depth) were set `reactive = 1.0` **and** +`disocclusion = 1.0` every frame in the camera kernel, and the merge kernel's +reprojection test re-flagged the whole sky as disoccluded every frame +(`!validDepth(currentDepth)` → `disocclusion = 1.0` → `reactive = 1.0`). +Silhouette reconstruction needs history on both sides of an edge, so the +sky-side suppression kept the boundary band strobing regardless of the +cutout-side policy. Vines are fully inside Sodium's single CUTOUT pass +(verified: Sodium 0.9 defines exactly SOLID / CUTOUT(discard) / TRANSLUCENT), +so their coverage was never the problem — a 1-2 px wide strip is 100% +edge-band with sky behind it. + +Fix (`metallum.metalfx.skyFarPlaneMotion`, default `true`, `false` = legacy): +cleared-far-plane pixels reconstruct camera motion at a substituted far depth +(`0.00002`) in both motion kernels — rotation produces correct flow, +translation is negligible at the far plane — and the merge reprojection +treats sky-onto-sky as valid history while geometry-onto-previous-sky and +sky-onto-previous-geometry still flag disocclusion. The tuning setter gained +a fifth argument (`skyFarPlaneMotion` 0/1) threaded through +`MetalNativeBridge`/`MetalFxConfig` like the others; `MotionUniforms.flags.y` +and a new `MergeUniforms.flags.x` carry it to the kernels. + +Also from the audit: the transparency mask now writes the actual compositing +strength (`clamp(coverage,0,1) × transparencyReactiveValue`) instead of a +binary presence bit, per FSR2's "write alpha" guidance — faint rain streaks +and cloud wisps no longer take a full 0.9 suppression. + +Complete reactive-writer audit (post-change status): + +| # | Writer (kernel : condition) | Value | Standing or transient | Verdict | +|---|---|---|---|---| +| 1 | camera v1/v2 : cleared far plane (sky) | was 1.0 | was standing every frame | **fixed** — far-plane motion, accumulates | +| 2 | merge : sky reprojection (`!validDepth(current)`) | was 1.0 via disocclusion | was standing | **fixed** — sky-onto-sky valid | +| 3 | camera v1/v2 : depth-edge heuristic | ≤ depthEdgeCap (0.5) | standing on silhouette band | capped §6.4; knob | +| 4 | dilation : cutout edge band / interior | 0.35 / 0.0 | standing on band | by design §6.2; knobs | +| 5 | transparency : translucent/itemEntity/particles/weather/clouds | alpha × 0.9 | standing where drawn | refined to alpha-proportional; knob | +| 6 | hand overlay : first-person coverage | max(existing, 0.35) | standing on hand | intended (swing/bob lacks per-vertex motion) | +| 7 | camera v1/v2 : reconstruction failures (`w≈0`, non-finite) | 1.0 | transient, degenerate frames | correct guard, keep | +| 8 | camera v2 : previous position offscreen / motion overflow (>32) | 1.0 | transient at screen edges during fast rotation | correct (no history exists), keep | +| 9 | merge : reprojection depth mismatch (true disocclusion) | 1.0 | one-frame transients on reveals | correct, keep | +| 10 | merge : object-motion invalid/overflow | 1.0 | transient guard | correct, keep | + +After #1/#2/#5, no standing full-suppression writer remains; every remaining +1.0 is a transient guard on pixels that genuinely have no usable history. + +**Row 9 turned out to be wrong.** See §15 — "one-frame transients on reveals" +is true for a translating camera, but under sub-pixel jitter a *static* +silhouette re-triggers it on alternating frames, which made it a standing +writer in disguise. It was the dominant remaining cause. + +## 15. Follow-up (2026-07-27c): the harness could not see the bug + +### 15.1 Why §14 measured as a no-op + +The §14 sky far-plane change validated as **bit-for-bit identical** to the +run before it (maskedMeanDelta 0.636798 → 0.636861). The cause was not the +change: the validation scene is a **sealed stone room**, built deliberately +in `installSceneClearing` so weather, distant terrain and drifting particles +cannot break byte-identical golden captures. Dumping `depth.bin` from the +`cutout_grass` capture gives a depth range of 0.0062–0.0355 and **zero** +cleared-far-plane pixels. The sky code path was never executed. A metric that +cannot reach the reported defect will report every candidate fix as a no-op. + +### 15.2 Sky-visible scene and sky-edge statistic + +`MetalValidationClient` gained a second hold. At frame 118 +(`SKY_SCENE_FRAME`, a scene-mutation frame so the section builder drains +first) `installCutoutSkyScene` opens the room ceiling, clears anything above +it — a no-op where the world is already open air — and suspends a +half-filled checkerboard of persistent oak leaves with `VINE` blocks +(all four faces set, so the quads render free-standing) threaded through the +odd cells. The checkerboard maximises silhouette edge per block. The camera +pitches to `SKY_SCENE_PITCH = -50°`: with a 70° vertical FOV the view spans +-15°..-85°, keeping the horizon and any distant terrain out of frame, so only +sky backs the foliage. Random ticks, weather, daylight and clouds are already +pinned by `applyDeterministicWorldState`, so the hold is static. Frames +128–151 are the `cutout_sky_hold` flicker series. + +`writeFlickerMetrics` gained three fields. Sky is classified from the same +cleared-far-plane test the motion kernels use (`≤ 0.00001`, reversed-Z), and +**sky-edge** is a *subset* of the existing mask — CUTOUT coverage *and* sky +in the same 3×3 render neighbourhood — so `maskedMeanDelta` stays comparable +with every earlier run: + +``` +"skyPixels": 174534, // 0 here is the tell that the scene has no sky +"skyEdgePixels": 88676, +"skyEdgeMeanDelta": 10.710036, +"skyEdgeP95Delta": 39 +``` + +`histogramMean` now returns 0 rather than `NaN` for an empty histogram; `NaN` +is not valid JSON and made the grass-hold file unparseable. + +### 15.3 Jitter phase pinning + +Before this, the Halton phase at the series start depended on how many frames +warm-up and terrain settling happened to render, which differs run to run and +moved both the coverage mask and the metric (`maskPixels` 292,961 vs 299,084 +across builds). `setFlickerCaptureFrame` now sets `phase = 0` on the series' +first frame — it is called from the timeline tick on the render thread, before +that frame's encode. With this, two runs of the same build produce **identical** +`maskPixels` and `skyEdgePixels`, so A/B arms compare pixel for pixel. + +### 15.4 Root cause of the sky-border strobe + +With the sky scene in place the band measured **10.90 mean / p95 39**, against +0.20 for the same scene's non-cutout control — 53×. §14's sky motion fix was +already enabled and did not help, because it addressed the wrong writer. + +`metallum_motion_merge_v2` ended with: + +```metal +if (!isfinite(disocclusion) || disocclusion > 0.5) reactive = 1.0; +``` + +and probed the previous depth with a single nearest-neighbour sample, +`uint2(previousPixel)`. At a foliage/sky silhouette the sub-pixel jitter moves +the edge by up to ±0.5 px per frame, so that probe lands on the *other side* +of the edge on alternating frames. Leaf depth (~0.01) against sky (0.00002) +always clears the `max(0.0025, |d|·0.01)` threshold, so the pixel is flagged +disoccluded — and slammed to `reactive = 1.0`, the exact full-suppression +value this whole remediation exists to remove. The silhouette therefore threw +away its history every other frame. Same defect class as the original, one +layer further down the pipeline. + +### 15.5 Fix + +Two changes, both knobbed: + +1. **Depth dilation** (`metallum.metalfx.mergeDepthDilation`, default `true`). + The reprojection probes a 3×3 neighbourhood and keeps the sample whose + depth is closest to the current pixel's, applying the sky substitution per + probe. `radius = 0` reproduces the legacy single probe exactly. A genuine + reveal — geometry over previous-frame sky with nothing closer nearby — + still flags disocclusion, so §14's semantics survive. +2. **Disocclusion reactive cap** (`metallum.metalfx.disocclusionReactiveCap`, + default `0.85`). `reactive = max(reactive, cap)` instead of `1.0`, matching + the policy already applied to the CUTOUT edge band and the transparency + mask. A disoccluded pixel still biases hard toward the current frame but + leaves the accumulator a share. + +The tuning setter went from five arguments to seven; `MergeUniforms` gained +`flags.y` (dilation) and `params.x` (cap). + +### 15.6 Measured + +Both arms are the same build, differing only in the two knobs, and produced +identical masks (`maskPixels` 299,624 / 271,748, `skyEdgePixels` 88,168): + +| Metric | legacy (cap 1.0, no dilation) | fixed (cap 0.85 + dilation) | Δ | +|---|---|---|---| +| sky hold, **silhouette band mean** | 10.9038 | **6.1804** | **−43.3%** | +| sky hold, **silhouette band p95** | 39 | **21** | **−46.2%** | +| sky hold, whole cutout mask mean | 4.5725 | 2.8557 | −37.5% | +| sky hold, whole cutout mask p95 | 25 | 14 | −44.0% | +| sky hold, control (non-cutout) | 0.2005 | 0.1485 | −25.9% | +| grass hold, mask mean | 0.9684 | 0.6096 | −37.0% | +| grass hold, mask p95 | 5 | 3 | −40.0% | + +Both arms: 10/10 GPU captures, including the `occluded_entity` and +`revealed_entity` disocclusion contracts. The control band improving too +confirms the 1.0 write was over-suppressing well beyond the cutout mask. + +### 15.7 Offscreen suite assertion updated + +`MetalFXOffscreenValidation.swift`'s `alpha_test` scenario asserted that +**every** CUTOUT coverage pixel carries `reactive > 127`. That invariant is +the pre-remediation full-suppression policy written down as a test: it only +held because every coverage pixel in the synthetic scene was disoccluded and +therefore 1.0. With dilation those pixels find valid history and correctly +drop to the edge (0.35) or interior (0.0) weight. Replaced with the two +assertions that express the current contract — the silhouette band still +carries reactivity (`≥ 72` on at least one coverage pixel), and no coverage +pixel reaches full suppression (`> 224/255`, above the 0.85 cap and below +1.0). This is a deliberate contract change, not a threshold relaxation. + +### 15.8 Still open + +- **Transparency `targetActivity` proportionality is unverified.** The sealed + room and the sky scene contain no water, glass or particles, so no run has + exercised it. The semantics follow FSR2's "write the compositing strength" + guidance and solid content whose target alpha or colour reads near 1 still + lands at ~0.9, but the claim is argued, not measured. + `-Dmetallum.metalfx.transparencyReactiveValue=1.0` restores binary behaviour. +- **`skyFarPlaneMotion` has no isolated A/B.** It is on by default and was on + in both §15.6 arms; its individual contribution was never separated because + the first attempt to measure it was lost to a concurrent-build failure. +- The residual 6.18 mean on the silhouette band is still ~30× the scene's + control. Sky/foliage contrast is far higher than the sealed room's, so some + of that is expected, but it has not been decomposed. + +## 13.

Every Metal 4 path is a parallel branch behind a default-off switch; the Metal 3 path is untouched and is what runs whenever a switch is off, the device or SDK lacks Metal 4, or the descriptor cannot be translated. - M1: metallum_metal4_supported folds the compile-time #available and the run-time supportsFamily(.metal4) into one answer. Switch metallum.opt.metal4. - M2 step 0 (the hard precondition): new metal4PipelineSmokeTest proves an MTL4Compiler pipeline state binds to an ordinary Metal 3 render encoder, so M2 needs no encoder changes and does not have to wait for M7. Green. It also shows one MTL4 pipeline is valid in passes with and without a depth attachment, since MTL4RenderPipelineDescriptor has no depth/stencil format. - M2a: NSMapTable weak-to-strong function -> library side table (MTLFunction does not expose its library, MTL4LibraryFunctionDescriptor requires it), plus the lazily built process-wide MTL4Compiler. - M2b: MTLRenderPipelineDescriptor -> MTL4RenderPipelineDescriptor translation and a new branch in metallum_MTLDevice_makeRenderPipelineState. Switch metallum.opt.metal4Compiler. - M2c archive half: MTL4PipelineDataSetSerializer replaces MTLBinaryArchive on the Metal 4 path, removing the "an archive loaded from disk can never be re-serialized" limit that forced S9A into read-only reuse. Java ABI unchanged; the archive is a sibling file (pso.mtl4archive) so flipping the switch does not cold-start the other mode's cache. - M3: MTLResidencySet on the existing Metal 3 queue (macOS 15 / iOS 18, no Metal 4 needed). Switch metallum.opt.residencySet. Synchronization layer: no fence or barrier semantics were changed. Nothing in this commit touches waitForFence/updateFence, the split-fence path, or the cross-queue event chain. The only submit-path change is a residency commit immediately before commandBuffer.commit() in metallum_MTLCommandBuffer_commit and _commitWithSignal, which is a no-op (one nil check) unless metallum.opt.residencySet is on. M6/M7e are where this line will touch the 34 fence sites, and that will be rebased onto the integration branch first. Three API truths that only running the code could reveal; all three are written back into docs/mtl4-api-probe.swift, still typecheck-green on macosx26.0, macosx14.0 and ios14.0: - The spec's M2c pairing of .captureDescriptors with serializeAsArchiveAndFlush(url:) is wrong. configuration is an NS_OPTIONS mask selecting which serializer method is usable; the archive flush needs .captureBinaries. The wrong pairing compiles and throws nilError at run time, so the pipeline cache silently never lands. A typecheck-only probe cannot catch this class of error, because that file is never executed. - A synchronous makeRenderPipelineState(descriptor:compilerTaskOptions:) overload exists, so lookupArchives does not force pipeline creation onto Swift concurrency. - Metal returns the same MTLFunction object for an identical library source, so a "library not registered, must fall back" test that reuses the same MSL still hits the side table and proves nothing. Distinct sources are required. Verification, all green: compileJava, compileTestJava, test, buildMacNative, buildIOSNative, metalMrtSmokeTest, and two new tasks run with MTL_DEBUG_LAYER=1 - metal4PipelineSmokeTest (API level) and metal4PipelinePathTest (links the shipping module and drives the real exports: capability gate agrees with supportsFamily, switch-on pipelines render pixel-identically to switch-off, an unregistered library falls back cleanly instead of returning nil, the archive flushes on both a cold and a warm launch, and the residency set adds, excludes memoryless, and removes correctly). buildIOSNative passing is what upgrades "no deployment-target bump needed" from a typecheck claim to a real build result. One-shot NSLog lines report which path ran ("Metal 4 pipeline path engaged" / "... unavailable, using Metal 3: "). Falling back is by design never an error, so without them a client run cannot distinguish the new path working from every pipeline silently degrading. Not implemented, deliberately: the flexible-PSO half of M2c (metallum.opt.metal4FlexiblePso). The spec's mechanism has no variant matrix to act on here - the six variants differ only in depth/stencil format, which the translation already drops - and capturing the saving needs the Java depth signature collapsed, which is unsafe while the Metal 4 branch can silently fall back to a depth-less Metal 3 pipeline used in a depth pass. Recorded for author decision in section 3 of the audit rather than worked around.

charset=UTF-8 Content-Transfer-Encoding: 8bit The frame graph compiler rejected a write to a Lifetime.EXTERNAL resource from any stage other than FRAGMENT, BLIT or PRESENT. That rule was not grounded in anything: a drawable can legitimately be written by a compute kernel, given shaderWrite usage, and several composition designs do exactly that. The stage check that remains — a pass may only use a resource from a stage the resource's descriptor permits — already covers the real constraint, because a descriptor that omits COMPUTE rejects a compute write on its own. Keeping the rule would have rejected valid pipelines for no benefit. The equivalent restriction was never added to the version pushed to the fork. The frame graph and native ABI layers themselves landed on this branch's history via fbff4d7, which snapshotted three sessions' concurrent work; this is the one correction made after that snapshot. 93 tests pass.

Pin the item's spin phase at its capture frame. ItemEntity.bobOffs is randomised per entity and final, so rather than pinning the offset the integer tick base absorbs it: getSpin is ageInTicks/20 + bobOffs, so choosing tickCount at the capture frame fixes the rendered angle there in every run. Two consecutive runs measured horizontal motion spread of 0.023 and 0.028 at frame 164 purely from that phase drift; pinning removes the variance and keeps the capture off the face-on phase, where a block item's visible face shares one depth and the spread carrying the rotation largely collapses. Clear pauseOnLostFocus before the level guard rather than inside applyDeterministicWorldState, which only runs once a level frame has been driven. Under Gradle the window usually opens unfocused and the pause screen opens on the same frame the player joins, before that first level frame; the paused unfocused client is then throttled to effectively zero frames and the timeline never starts. Three runs on 2026-07-27 exited reporting success having captured nothing. This does not fully close the hole — the task still cannot tell "validated" from "never ran" — so the Gradle-side run-state assertion is tracked separately.

Lower it to 0.008. This costs nothing in detection power.

Falling blocks and block entities render through core/block, so they reached the interpolator with no object motion and their movement was left to disocclusion rejection. This is the gap the frame generation doc's Known limits and the attended QA checklist's §3 both name. Verified against the 26.2 sources rather than assumed: RenderPipelines BLOCK_SNIPPET builds SOLID_BLOCK, CUTOUT_BLOCK and TRANSLUCENT_BLOCK on core/block with DefaultVertexFormat.BLOCK; RenderTypes builds SOLID_MOVING_BLOCK, CUTOUT_MOVING_BLOCK and TRANSLUCENT_MOVING_BLOCK on those; and FallingBlockRenderer.submit reaches them via submitMovingBlock. The one thing that separates the family from core/entity is the clip transform. core/entity uses ProjMat * ModelViewMat * Position; core/block uses ProjMat * ModelViewMat * (Position + ModelOffset). Replaying block geometry with the entity shader would produce motion vectors that look plausible and are wrong, which is worse than producing none. ModelOffset lives in the shared DynamicTransforms block that the source pipeline already binds, so the reduced shader reads the same value the color pass used and needs no new uniform. Attribute locations 0/1/2 hold Position, Color and UV0 in both formats, so the explicit-location declaration carries over unchanged; BLOCK's ivec2 UV2 at location 3 is left undeclared because the lightmap is not read. Family is now an enum keyed on the vertex shader path, each member owning its shader and its pipeline location prefix, and build() fails closed for a source no family claims instead of silently using the entity shader. blockMotionDrawsEncoded joins itemMotionDrawsEncoded as a subset counter of motionDrawsEncoded, so a scene with a falling block in view and a zero there localises the failure to this path. Not yet reachable at runtime, deliberately: the sample carrier is attached in ModelFeatureRenderer.prepareModel and ItemFeatureRenderer.prepareSubmit, and moving blocks go through MovingBlockFeatureRenderer instead. Until that hook exists MODEL_BUILD is null for a moving-block draw, shouldSplitEntityDraw declines it, and blockMotionDrawsEncoded stays zero. Hooking MovingBlockFeatureRenderer is the next unit; this commit is the family it will feed. 98 tests pass. MetalMotionFamilyTest asserts each family's shader assets exist, that the prefixes cannot collide, that only the block shader applies ModelOffset, and that both shaders keep explicit attribute locations — the mistake that silently discards every fragment.

The present thread is the pilot because no Java ABI crosses it, one command buffer carries at most an interpolator encode plus a three-vertex copy, the binding surface is one texture and one sampler, and it touches no MTLFence. Switch metallum.opt.metal4Present, default off, gated on metal4Compiler because the MTL4 frame interpolator is built from an MTL4Compiler. Synchronization layer: the main queue is not touched, and no fence semantics change. What moves is only the *wait* side of the existing cross-queue MTLSharedEvent: the main Metal 3 queue keeps calling encodeSignalEvent exactly as before, while the present queue waits with MTL4CommandQueue.waitForEvent instead of MTLCommandBuffer.encodeWaitForEvent. Shared events cross the Metal 3 / Metal 4 boundary, which is what makes this pilot possible in isolation. Metal 4 fences are same-queue only, so a pilot that used fences would have collided with the main queue's fence chain immediately - that is why this path was chosen and not another. Nothing here overlaps the 34 main-queue fence sites, which stay for M6/M7e. - New Metal4PresentPath owns only the Metal 4 mechanics: queue, one reusable command buffer, a two-deep allocator ring (maxOutstandingFrames is 1, and one allocator would be wrong because reset() reclaims memory the GPU may still be reading), a 1-texture/1-sampler argument table with initializeBindings, and a residency set plus the layer's read-only drawable-tracking set. - present(_:) dispatches two ways; the entire Metal 3 branch below the dispatch is unmodified. presentMetal4 duplicates the lifecycle, deadline and diagnostic bookkeeping on purpose rather than factoring it out, so the Metal 3 path stays as it was. - installTextureSet is the single choke point every rebuild path funnels through, so the residency republish hook lives there. A resize additionally rebuilds the MTL4 interpolator, and clears metal4Path with it on failure so dispatch reverts to Metal 3 rather than running with a stale interpolator. - MTL4CommandBufferFeedback has no status, only error, so success is error == nil. It routes into the existing handlePresentGPUCompletion, which keeps the failure path that advances readyEvent - without that the present thread would hang on a stale wait. - Ordering differences that matter: the event wait is issued only once the frame is certain to be committed, so a frame dropped by the deadline check does not leave a wait on the queue timeline; and the reusable command buffer is closed on every exit path via abandonFrame(). Two API truths found by running the code, both now in docs/mtl4-api-probe.swift: - MTL4CommandQueue.label is get-only, unlike MTLCommandQueue's. The spec's M4 skeleton line `queue.label = "..."` does not compile; the label has to come from MTL4CommandQueueDescriptor, and that overload throws. - A Metal 3 pipeline state binds to an MTL4 render encoder with its texture and sampler supplied by an argument table. This is the reverse of the M2 question and had to be checked separately, because the presenter's copy PSO is built by the ordinary Metal 3 factory. metal4PipelineSmokeTest now covers it, under MTL_DEBUG_LAYER. Verification, all green: compileJava, compileTestJava, test, buildMacNative, buildIOSNative, metalMrtSmokeTest, metalFrameGenerationLifecycleTest (9), metal4PipelineSmokeTest and metal4PipelinePathTest. The path test now drives the real Metal4PresentPath headlessly: the whole object graph builds, the MTL4 frame interpolator factory returns non-nil on this device (had it returned nil the present path would have fallen back to Metal 3 permanently and silently), the copy encodes through the shipping encodeCopy, and the four-step waitForDrawable / commit / signalDrawable / present handshake completes with a correct pixel readback. Not yet verified, environment-blocked: the visible-window pacing acceptance (presentedTime non-zero, deadline misses not increasing, 10 minutes without deadlock). New task metal4PresentValidation runs the existing presentation validation harness with the Metal 4 path enabled, but that harness currently fails identically on the Metal 3 baseline and on the integration branch with no M4 code at all ("Expected at least 4 generated presentations, found 0"), because it needs a WindowServer-composited visible window. It has to be re-run from an interactive session before M4 can be called accepted.

Both changes are on the one path whose failure mode is a permanently wedged present queue, so they are worth taking even though the hazard was already avoided. Synchronization layer: no semantic change. The main queue is still untouched and no fence is involved; this only moves where the existing cross-queue MTLSharedEvent wait is issued from, within the same thread and queue. 1. queue.waitForEvent moves inside submit(), and the standalone waitForReady is gone. Metal 4's queue wait is a queue-timeline operation that takes effect when called, unlike Metal 3's encodeWaitForEvent which is recorded into the command buffer and disappears with an unsubmitted buffer. present(_:) returns from four places after encoding and before commit, one of which — the deadline-miss guard — fires in normal operation. A wait issued before those returns would be an orphan nothing satisfies, and every later commit would queue behind it. The wait was already placed after all four returns, so behaviour is unchanged; what this removes is the ability to put it back in the wrong place, which a separate waitForReady(event:value:) invited. The reason it must sit there is now documented on submit() itself. 2. Frame closing is idempotent via an isRecording flag, so abandonFrame() can be called unconditionally on every exit path (all four already did) without the reusable command buffer being closed twice or closed when never opened. New regression test in metal4PipelinePathTest for exactly the deadlock that placement guards against: encode a frame and abandon it the way the deadline path does, call abandonFrame twice to confirm idempotency, then require a real frame to still encode, submit and complete within 5s. If the wait were issued early this fails by timing out rather than by silently passing. This is the headless half of the "deadline misses repeatedly, is the queue still alive" question that the 10-minute soak is meant to answer. Three review points needed no change, recorded so they are not re-raised: - drawPrimitives on an MTL4 encoder is drawPrimitives(primitiveType:...), not Metal 3's type:. The code already uses the MTL4 spelling. - The Metal 3 copy pipeline on an MTL4 encoder with argument-table bindings was flagged as unverified. It is verified: metal4PipelineSmokeTest gained a case for that direction specifically, under MTL_DEBUG_LAYER, because the M2 step-0 case proves the opposite direction and does not cover it. - NativeState.metal4PresentEnabled, the export, the Bridge downcall and MetalDevice.METAL4_PRESENT are all present and L1 is green. Verification, all green: compileJava, compileTestJava, test, buildMacNative, buildIOSNative, metalMrtSmokeTest, metal4PipelineSmokeTest, metal4PipelinePathTest and metalFrameGenerationLifecycleTest (9). Still environment-blocked, unchanged: the visible-window pacing acceptance (metal4PresentValidation), which needs a WindowServer-composited window and fails identically on the Metal 3 baseline here.

The scenario swaps are staging only, fenced by a history reset 8 frames ahead of each capture, and nothing validates a reveal with them. Every angle these three drive is read through a partialTick lerp of old -> new, so pinning old == new leaves them free of any wall-clock term. The minecart is the exception by construction: on a straight rail the renderer re-derives orientation from the front/back rail samples and discards the cart's own yaw, so the hurt shake is the only rotation available without curving the track, and its wobble is asserted on the axis-agnostic spread because it rolls about X rather than yawing. Minecarts under the new behaviour are deliberately absent. That path needs FeatureFlags.MINECART_IMPROVEMENTS, and the validation world enables only minecraft:vanilla, so AbstractMinecart always constructs OldMinecartBehavior here. Reaching it means changing the shared world's enabled features, which would move every existing golden capture. Expected captures 12 -> 15; the timeline now runs past the old 220-frame ceiling, so the timeout moves to 300. Compiles and the 93 unit tests pass, but these three frames have not yet been through a client run - the validation client has been continuously occupied by another session. Thresholds reuse the envelope already calibrated against real item and boat captures.

SUCCESSFUL having asserted nothing. If the client window opens unfocused, the pause screen opens on the same frame the player joins, the compositor throttles the paused unfocused client to roughly zero frames and MetalValidationClient.beforeFrame never reaches a frame with a non-null level. The scripted timeline never starts, no GPU readbacks are captured, no run-state.json is written, and runClient still exits 0. Three runs on 2026-07-27 did exactly that: run/logs/2026-07-27-6.log.gz and -7.log.gz have no "GPU readback" lines yet the build succeeded. c32f04b cleared pauseOnLostFocus before the level guard, which narrows the race but cannot distinguish "validated and passed" from "never ran". Close that by asserting on the artifact instead. finishRunState is the only writer of run-state.json and the client calls minecraft.stop() only on its success path, so an absent file is exactly the vacuous case. runClient gains a doLast, active only under the existing minecraftMetalFxClientValidation start-parameter guard, that requires the file to exist, parse, report status "passed", and have completedGpuCaptures equal expectedGpuCaptures. The expected count is read from the file rather than hard-coded so the gate follows the client: the recorded golden baseline still carries expectedGpuCaptures 10, so a literal 12 would have rejected it. doLast rather than a finalizer because runClient is Loom's RunGameTask with ignoreExitValue false, so the genuine-failure and 220-frame-timeout paths already fail the task on a nonzero exit. The doLast is the net for the exit-0 cases, and also catches an exit-0 run that wrote status "failed". Verified by extracting the doLast body into a standalone Gradle harness and running it against ten cases, two of them real run-state.json files from the tree: missing file, status failed, 8-of-12, the iris 9-of-8 failure, passed-but-short-count, truncated JSON, missing fields, null status, 12/12, and the 10/10 golden baseline. Task-graph attachment confirmed (three actions on RunGameTask); both the guard-active and guard-inactive configuration paths evaluate clean.

The sample carrier is made current in ModelFeatureRenderer.prepareModel and ItemFeatureRenderer.prepareSubmit, and moving blocks go through MovingBlockFeatureRenderer, so MODEL_BUILD was null for every moving-block draw, shouldSplitEntityDraw declined it and blockMotionDrawsEncoded stayed zero. These are the two hooks that close that. MovingBlockFeatureRenderer.Submit is constructed inside FallingBlockRenderer.submit, which runs between beginEntitySubmission and endEntitySubmission, so the owner is recorded there while it is still on the stack. The build-time bracket needed a different shape from the entity and item families. Those hook a private per-submit method; buildGroup inlines its per-submit work in the loop body, so the submit exists only as a local. Rather than capture locals, which pins the hook to a local variable table, the bracket wraps the one call that emits a whole submit's geometry — ModelBlockRenderer.tesselateBlock — whose level argument is the submit's own MovingBlockRenderState. That is also the key the submit constructor recorded the owner under, so the two ends meet without either needing the submit record. The wrap spans exactly the window in which Group.getVertexBuilder and getOrAddDraw run, which are the points that split a draw out and bind it to the sample. A redirect rather than paired injections, because the sample has to be cleared even if tesselation throws. A HEAD/RETURN pair around a call cannot express that, and a leaked sample would attach this block's motion to whatever geometry is built next — silently wrong motion vectors rather than none. Moving blocks are keyed by render state and the owner is retained rather than consumed: one block model can tesselate into the solid, cutout and translucent render types, and beginFrame clears the map every frame so retaining cannot leak across frames. Verified statically, since this cannot be reached from a unit test: the redirect's descriptor is byte-for-byte the invokevirtual in buildGroup's bytecode and occurs there exactly once, the Submit constructor is (Matrix4fc, MovingBlockRenderState, int) as the injection declares, and both mixins are registered — with defaultRequire 1 a descriptor that stopped matching would fail at class load rather than degrade quietly. Still unproven at runtime: that blockMotionDrawsEncoded goes non-zero with a falling block in view. The automated client validation drives an armour stand, and adding a falling-block scenario means editing MetalValidationClient, which belongs to the cutout-shimmer line. Recorded rather than done. 100 tests pass. MetallumMixinRegistrationTest now guards both directions of the mixin config, the failure this commit would otherwise have been one json line away from: a hook that compiles, ships and does nothing.

Half of that is no longer true and the other half was imprecise, and this file is the truth source the attended QA checklist sends a human to before judging the gate — so an overstated gap costs QA time on something already covered, and a vague one hides what is actually missing. Object-motion coverage now states the family concept and both families in a table with their format, clip position and replay shader, and names the two renderers that emit core/block geometry: FallingBlockRenderer, which is covered, and PistonHeadRenderer, which is not. Known limits now says why the piston case is still open, which is not the shader side: the BLOCK family replays it fine, but beginEntitySubmission is called only from EntityRenderDispatcher.submit — verified, it has exactly one caller — and BlockEntityRenderDispatcher is not hooked at all, so no submission window is open when a block entity's submits are constructed. That single missing piece is what blocks every block entity, not just the piston: a chest rendering entity-format models through ModelFeatureRenderer is in a family that can replay it and has no sample to replay it with. It also records why the fix cannot be done from this line alone. The current/previous pair has to come from the manager's own MetalMotionStateStore, which commits only once a frame's output has been encoded; a second store kept outside would commit on frames the manager discarded and then hand out a previous transform that was never presented, which is the failure that store's design comment exists to prevent. So it needs an entry point next to MetalFxManager.captureEntityMotion, in a file the cutout-shimmer line owns.

M5 is code behind no switch of its own (it activates with metallum.opt.metal4Main in M7); M6 is a design deliverable with no behaviour change at all. Synchronization layer: nothing changes yet. M6 only *documents* the barrier pairs; no fence call site is touched, and the 27 sites it maps are all still Metal 3 fences. M7e is where they change, and it must rebase before starting. M5 - Metal4BumpAllocator plus Metal4BumpAllocatorRing. Metal 4 removed set*Bytes entirely, so uniforms are copied into shared-storage memory and bound by GPU address through an argument table. Sizing is measured rather than guessed: the seven remaining set*Bytes sites push ClearUniforms 48 B (the only vertex one and the only one that can repeat per clear), CutoutReactiveUniforms 32 B, HandOverlayUniforms 16 B, SIMD2 8 B, TransparencyMaskUniforms 48 B, MergeUniforms 48 B, and MotionUniforms 240 B, the largest at three 4x4 matrices plus three vectors. All have alignment requirements of at most 16 B. 64 KiB per frame therefore holds 272 largest-case uniforms, at 256 KiB across the ring. Ring depth is MAX_SUBMITS_IN_FLIGHT + 1 = 4, the same as the destruction queue depth from S1 and for the same reason: an allocator may only be reset once every submit that could still be reading it has completed. Sharing one allocator would overwrite uniforms the GPU is still fetching, and the symptom would be intermittently wrong values rather than a crash. The arena registers itself with the residency set on creation, because an address into a non-resident buffer is a read of unmapped memory under Metal 4. Overflow returns nil and logs once, so a dropped binding can never be silent. Note for the record: the spec says eight set*Bytes sites; the tree has seven (one setVertexBytes and six compute setBytes, verified by anchor not line number). M6 - docs/metal4-barrier-map.md, the construction drawing for M7e. Every fence call site is enumerated from string anchors and mapped to its Metal 4 barrier pair, with the encoder type of each confirmed against its make*CommandEncoder call. The spec's acceptance says 34 fence sites. The tree has 27 *semantic* ones - 20 Swift, 7 Java - and 17 further lines that are forwarding shells: four @_cdecl export bodies, one makeFence, four mtl-package wrapper methods and eight Bridge downcall lines. The map states this reconciliation explicitly and lists what was excluded and why, so a review can check the exclusions rather than trust the count. 34 sits between the two totals and most likely included the export bodies. Three findings that change how M7e must be written: - The four frame-generation input-blit sites cross the main queue and the present queue, and M4 already moved the present queue to Metal 4. Metal 4 fences are same-queue only and barriers are per-queue-timeline, so these can only ever be MTLSharedEvent - not fences and not barriers. Flagged as the single easiest cell in the table to get wrong, with a pre-landing check for which queue that encode belongs to. - One pair is dispatch to dispatch (the v2 camera encoder feeding the merge encoder), not the .fragment shape the other four compute pairs use. - The resource-alias edge has no Metal 3 counterpart at all: transient block recycling and buffer-pool reuse repoint the same virtual address, which Metal 3 covers implicitly via destruction-queue depth. It is the one edge M7e must add from nothing, and missing it reads stale contents without any error. Every barrier spelling in the map was typechecked rather than assumed, including that MTLStages is an OptionSet - which is what lets the three combined-stage rows (J5/J6/J7) stay one barrier each instead of two, avoiding a second cache flush. Verification, all green: compileJava, compileTestJava, test, buildMacNative, buildIOSNative, metalMrtSmokeTest, metal4PipelineSmokeTest, metal4PipelinePathTest and metalFrameGenerationLifecycleTest (9). The new bump-allocator case is a real GPU read, not pointer arithmetic: it allocates behind a deliberately odd-length allocation, checks 16-byte alignment and non-overlap, confirms 272 largest-case uniforms fit, confirms overflow is refused and logged, confirms ring rotation recycles the arena, then binds the address through an argument table and requires the fragment shader to read back exactly the bytes written. Open items unchanged, both recorded in the audit for author decision: the M2c flexible-PSO depth-signature collapse, and M4's visible-window pacing acceptance which is environment-blocked here.

M7 as a whole is all-or-nothing (a Metal 4 command buffer cannot carry Metal 3 encoders, so the main queue switches entirely or not at all), so nothing here is wired in yet and behaviour is unchanged. Synchronization layer: no fence or barrier call site is touched. The barrier calls added are inside a test, not in the render path. M7g - metal4WaitForCompletion. Neither MTL4CommandQueue nor MTL4CommandBuffer has waitUntilCompleted, so a CPU wait becomes signalEvent plus MTLSharedEvent.wait(untilSignaledValue:timeoutMS:). It keeps the Metal 3 export's contract of distinguishing timeout from completion, which its caller (Encoder.awaitSubmitCompletion) needs for glClientWaitSync semantics. The GL semantics and the implicit flush S10 corrected stay on the Java side untouched; only the waiting mechanism changes. Each submit needs its own increasing value paired with the existing submitIndex, or a later wait would be satisfied by an earlier submit - noted at the definition. M7h - the spec's translation table is incomplete, and that is the finding here. It lists three copy shapes; the tree uses four. The two it omits are texture to texture with an origin and size, and texture to buffer. Both now have verified spellings: the rule throughout is that Metal 3's from:/to: become explicit sourceX:/destinationX: labels naming both ends. Also recorded: the tree has no generateMipmaps and no fillBuffer at all, so those two rows of the table have nothing to convert today (S12's generateMipmaps ABI is planned, not landed), and there are three makeBlitCommandEncoder sites rather than the spec's five. No forwarding wrapper was written for the copy shapes. Wrapping cenc.copy(...) in a function that only forwards would add indirection without value; what M7a actually needs is confidence in the spellings, which is what the test provides. New test case chains all four copies - buffer to buffer, buffer to texture, texture to texture with a region, texture to buffer - through one MTL4 compute encoder with distinct per-pixel values, then asserts every byte survives the round trip. The chain carries an explicit same-encoder barrier between each step, because Metal 4 has no hazard tracking and consecutive dependent copies would otherwise read stale data; that makes the chain a working demonstration of the barrier form M7e needs. The M7g timeout path is asserted first, before the success path, so that a wait helper which always reported success could not make the rest of the assertions vacuous. Verification, all green: compileJava, compileTestJava, test, buildMacNative, buildIOSNative, metalMrtSmokeTest, metal4PipelineSmokeTest, metal4PipelinePathTest and metalFrameGenerationLifecycleTest (9). Remaining for M7: M7a (queue, allocator ring, command buffer lifecycle), M7b (render pass descriptors), M7c (45 argument-table bindings), M7d (indexed draws), M7e (the 27 barrier pairs plus the resource-alias edge, per docs/metal4-barrier-map.md), M7f (deferred destruction). The switch cannot be enabled until all of them land.

_bindTexture(0)`。MC 26.2 的 +`_activeTexture` 在请求单元 ≠ 缓存值时**真的调 `GL33C.glActiveTexture`**;缓存初值 0, +所以 `i=0` 被静默吸收,**`i>=1` 每次都是无上下文的实 GL 调用**。 +至今没炸只是因为循环体遍历 `pipelinesPerDimension`,首次进世界时为空。 +**退世界 / 切维度 / F3+R / 关光影,只要之前存在过一个 pipeline 就会执行到。** +修:新增 `IrisPipelineManagerCompatMixin`(`resetTextureState` HEAD cancel),已进 mixins.json。 +取消是安全的——它的目的就是把 GL 纹理单元恢复到已知状态,Metal 上没有这种状态, +绑定都在 `MetalRenderPass` 里逐 pass 重建。 + +**② MetalFX TEMPORAL 会静默绕过 Iris 对 CUTOUT 的覆盖(已加 warn-once,未解决)**。 +`ShaderChunkRendererMetalFxMixin` 在 `compileProgram` HEAD 直接返回 +`metallum:pipeline/terrain_cutout_reactive`——命名空间不含 "sodium", +`isSodiumPipeline` 判 false,`tryCompile` 返回 null 且**一行日志都不打**。 +BSL 的 CUTOUT(`[0]`,本该生效)在 TEMPORAL 下会退回 metallum 自己的 shader。 +`MetalFxConfig` 默认 OFF 所以现在不踩,**阶段二一开就爆**。已加一次性 warn; +真正的重叠解决属阶段二。 + +**③ reload 生命周期两个真 bug(已修)**: +- `Instance.close()` 的 `clearPipelineCache()` 被 `this.device != null` 门住,而 `device` + 只在 `compileOverride` **成功**时赋值 → 某 pack 期间一个覆盖都没编译成功就永远不清缓存。 + sodium 的 `ShaderChunkRenderer.programs` 是 `private static final Map`,跨 JVM 不变, + 于是原生 PSO 一直留着换不掉。复合效应:`pipelineCacheGeneration` 只在 `clearPipelineCache()` + 里递增,那道防后台编译串代的保护一起失效。修:回落到 `MetalDevice.current()`,无条件清。 +- `activate()` 不关前一个 Instance → 泄漏 uniform buffer + placeholder 纹理。 + 修:`activate()` 开头先 `deactivate()`(幂等)。 + +**④ 另两条(已修)**:`compileOverride` 补 `closed` 检查(后台 prewarm 线程的编译任务可能 +跨越一次 deactivate/activate);`prewarm` 加一次性 INFO +`draw-path resources prewarmed for generation N`——**没有它,「Iris 的 LevelRenderer 钩子 +在 Metal 上没生效」和「资源确实缺失」两种完全不同的根因会表现为同一条 `Missing sampler`**。 + +**⑤ 更正一条此前的判断**:05:55 那轮没有 `compiling terrain override` **不是 `discriminate` +判错**,只是客户端停在标题画面没进世界(sodium 的 `compileProgram` 只在地形真要画时才被调)。 +`discriminate` 经字节码交叉验证与 Iris 生产逻辑逐条等价。 + +**未做,留给下一轮(按风险序)**: +- S6b 不是槽位顺序问题而是**硬互斥**:`validateFragmentOutputSignature` 要求 fragment 输出 + location 集合与非 null color target 下标集合**完全相等**,coverage 与 Iris 扩展附件 + **不可能共存于同一 pass**;且布局对 generation 冻结而 `usesCutoutReactiveTerrain()` 逐帧可变 + → **任何「按帧动态决定布局」的方案必然某帧撞闸崩溃,互斥必须是 per-generation 静态决策**。 + 另:`extendedKindMask` 应在 `Instance` 构造函数末尾就定死(否则 asyncPrecompile 可能在进世界前 + 用旧标志编出原生 PSO 并永久留存);扩展槽错序 100% 静默(格式全是 RGBA8_UNORM,三道闸都不响), + 必须加防错序自检;改附件布局后必须 `rm -rf run/metallum-cache/msl`(MSL 磁盘缓存的 key + 不含 colorTargetStates,会跳过第一道闸)。**§4.3 那份配方对 `db[0] != 0` 是错的** + (Potato TRANSLUCENT=`[3,4]`,slot0 也是 colortex 而非主帧缓冲)。 + 推荐方案不需要动 `MetalRenderPass.java` → 对 Metal 4 线零新增冲突面,**刻意保持**。 +- 性能审计 P1 已过时:按管线 fragment-stage 等待**已在树里**(`SPLIT_FENCE` + `waitRenderFences`), + 默认关,不需实现只需验证+打开;但它是**无条件收窄而非按管线反射**,composite 链里若有 pass + 在**顶点阶段**采样上一 pass 输出,split 模式下会欠同步——打开前必须补对抗用例。 + ## 5. 风险与预案 | 风险 | 信号 | 预案 | diff --git a/logs/2026-07-27-1.log.gz

The minecart was left on its rail during every other object scenario on the claim that it was out of frame. It is not: the rail sits about 23 degrees below the horizon at that distance against a 35 degree half-FOV, so a resident cart added a second silhouette of zero-motion object pixels to the item, boat, pig and arrow measurements — and on its own would have cleared the arrow scenario's pixel floor, making that assertion vacuous. Park it like the others. The original rationale was wrong anyway: OldMinecartBehavior.getPos is evaluated from the cart's current position every frame rather than latched, so the rail-sampled branch re-selects itself the moment the cart is back on the track. The hurt shake counted hurtTime down a step per frame, but hurtTime is fed to sin as if it were radians, so 10 -> 9 at damage 40 swung 36 degrees in a single frame — the large per-frame motion these scenarios exist to avoid. Hold hurtTime fixed and ramp damage instead: the angle is then linear in the ramp at a steady 1.9 degrees a frame. A missing rail made the reconstruction fall back to the non-rail branch silently, and the scenario would still have passed on the shake alone while covering a different code path than it claims. Assert the rail is present.

With defaultRequire at 1 a stale descriptor is fatal rather than silent, but it is fatal during client startup — after the build went green, after a jar could have been built, and with a stack trace that names the mixin rather than the Minecraft method whose shape moved. A Minecraft update is exactly when that happens and exactly when nobody is looking for it. The descriptors now live in MetalMotionHooks as compile-time constants, which is what lets the annotation reference them, and MetalMotionHookDescriptorTest reads the real signatures back off the test classpath and compares. It loads the classes without initialisation, since reflection over members does not need a static initialiser and Minecraft's would want a game environment this JVM does not have. Three checks: ModelBlockRenderer.tesselateBlock has exactly one overload and its descriptor matches; MovingBlockFeatureRenderer.Submit has exactly one constructor and its parameter list matches what the injection declares; and the target string is still composed of the name and descriptor the other two verified, so the checks cannot pass while the thing Mixin actually matches on has drifted. The overload and constructor counts are asserted because an added overload makes the injection ambiguous rather than absent, which fails differently and is worth naming separately. Negative-verified rather than assumed: changing BlockAndTintGetter's package in the descriptor turns tesselateBlockStillHasTheDescriptorTheRedirectTargets red, and restoring it turns it green. A guard that cannot fail is not a guard. 103 tests pass.

One item is a real defect in code already landed; the rest reworks the M6 deliverable, whose methodology was wrong. Synchronization layer: still no fence or barrier call site touched. M6 remains a document. M5 - the overflow contract was wrong. The spec says a failed allocation must fall back to the old path; there is no old path, because set*Bytes is absent from every MTL4 encoder (confirmed against the SDK headers, zero hits). The landed code logged "falling back to the Metal 3 path", which in practice would have meant a draw with no uniform bound at all. Replaced with an overflow chain: the allocator holds chunks and appends one when the current is full, so the first frame that overflows pays an allocation and later frames reuse it; reset only rewinds. Growth deliberately uses makeBuffer rather than a transient block through the destruction queue, because that route would force a residency commit() per overflow and M3 establishes that commit() is the one expensive residency operation and must happen at most once per submit - appending only marks the set dirty. Nil is now returned only for a single allocation larger than a whole chunk, which chaining cannot fix and which nothing here approaches at 240 B. M6 - the first version enumerated fence call sites and translated each, which is what the spec prescribes. That method structurally cannot find an encoder that has no fence, and two exist: - metallum_metalfx_mark_transparency, a compute encoder reading five render-pass outputs and writing reactive, with zero fence calls and no fence parameter in its ABI at all. The adjacent encodeCutoutReactiveMask does take one, so this is an omission rather than a design. - the historyBlit inside metallum_metalfx_encode_motion_v2, reading depthTexture and writing previousDepthTexture, with zero fence calls. Both work on hazardTrackingMode = .untracked textures, so the driver does not back-stop them: this is already a latent race under Metal 3 that current Apple GPU scheduling happens to hide, and a deterministic bug under Metal 4. Per M0.10 this records it and does not touch the Metal 3 path; recommended as a P0-class item in the audit, alongside P0-1/P0-2/P0-3, since it is correctness rather than performance. The map is now organised per encoder - all 17 Swift factory sites plus the two Java factories - so an empty wait/update cell is visibly a gap. Four further corrections, each verified rather than taken on faith: - Barriers do not need pairing. The header defines the consumer form as covering every matching stage previously committed to the queue and the producer form as covering all subsequent encoders, so either alone is a complete cross-encoder edge. The spec gives both sides for every row plus a blanket .device, which would leave Metal 4 with more synchronisation points than the current fence chain - and M7's acceptance includes System Trace being no worse than Metal 3, so following the spec here would fail that on purpose. Now one consumer-side barrier per edge. - .resourceAlias does not apply and is removed. Its stated justification is transient block recycling repointing a virtual address, but MTLHeap usage is zero, recycleDynamicBacking returns whole MTLBuffer handles and MetalTransientMemory recycles whole objects - one resource changing purpose, not two resources over one physical page. The only true aliasing is the buffer-backed texture view, and Apple's own synchronisation guidance uses .device there; .resourceAlias documents itself as potentially flushing to the system coherence point, i.e. heavier. - scaler.fence must survive. It lives on MTLFXTemporalScalerBase / MTLFXFrameInterpolatorBase, MTL4FX* inherits it, and this project assigns it in two places. The spec folds it into "replace all fences with barriers" while M7e says to delete cross-encoder fences - but it is cross-encoder and required. M7e's deletion scope now excludes it explicitly. - The fence count is not a usable acceptance criterion. Java has 7 semantic sites of which 3 are mutually exclusive under SPLIT_FENCE, so 4 or 6 are live at run time; Swift has 20. Coverage is now defined as all 17 encoders. R6-1, the one place M7 reaches back and breaks landed M4 code: MTL4CommandBuffer has no encodeSignalEvent, and MTL4CommandQueue.signalEvent is documented as firing after all GPU work "prior to this point", meaning the queue timeline. The frame generation input copy currently signals readyEvent immediately after blit.endEncoding(), where position is the semantics. Translating that literally to queue.signalEvent before commit would order the signal ahead of the copy's own commit, releasing the present thread onto a half-written frame - tearing with no error reported. It is the mirror image of the waitForEvent hang already fixed in M4. Two options are written up with a recommendation (split the input copy into its own MTL4 command buffer and signal right after committing it); the alternative costs the present thread a whole frame of main-queue work and collides with M4's own deadline acceptance. Two smaller findings recorded: the existing long stages Bridge ABI can be reused unchanged for Metal 4 barriers because MTLRenderStages values are bit-identical to MTLStages in the low bits (needing only Dispatch 1<<27 and Blit 1<<28), and the six MetalFX @_cdecl entry points take MTLCommandBuffer, which under M7 receives an MTL4CommandBuffer through an unchecked ObjC bridge and would dispatch a non-existent selector, so they need MTL4 twins landed with M7a/M7c. Verification, all green: compileJava, compileTestJava, test, buildMacNative, buildIOSNative, metal4PipelineSmokeTest, metal4PipelinePathTest and metalFrameGenerationLifecycleTest (9). The bump case now proves growth: 554 largest-case allocations succeed across 3 chunks, an oversized request is refused, rotation recycles, and the GPU still reads the uniform at the returned address.

That path copies the source's defines, bind group layouts, vertex bindings, topology and cull state, swaps in the family's shader, attaches the two motion targets and disables depth write — and a variant that came out wrong would first be noticed as a frame that quietly produced no motion, or worse, produced motion over the wrong pixels. Sources are synthesised with RenderPipeline.builder rather than taken from RenderPipelines, so the test does not need that class's static initialiser to run outside a game. What is under test is this mod's build(), not Minecraft's constants. Nine checks, each on something that fails silently rather than loudly: - core/block is claimed by BLOCK, core/entity by ENTITY, and core/terrain by neither — terrain adds a chunk offset this backend does not reconstruct, so a family claiming it would emit confidently wrong motion. - A block variant replays with the block shader and lands under its own location prefix; an entity variant still uses the entity shader, which is the regression adding a second family invites. - Slot 0 is RG16_FLOAT, slot 1 R8_UNORM, and slot 0 is unblended: a blended motion target would average vectors from different surfaces. - Depth write is off while the depth test is preserved, including a non-default compare op. Writing depth would let the replay change what the scene sees; changing the test would make it cover different pixels than the color pass. - ALPHA_CUTOUT survives into the variant. Without it a cutout block's motion covers its whole quad rather than its visible fragments. - The source's vertex binding survives, since the variant reads the buffer the color pass filled. - A translucent source is still claimed by the family but not supported, because a blended source has no single owning surface per pixel. - Variants are cached per source and dropped by clear(), so a source does not rebuild every frame and a resource reload does rebuild. 112 tests pass.

The new one is not reachable by configuration here: AbstractMinecart selects NewMinecartBehavior only when the level enables FeatureFlags.MINECART_IMPROVEMENTS, and the validation world enables minecraft:vanilla alone. Turning that flag on would change a world three sessions share and move every existing golden capture. It is reachable without touching the world. AbstractMinecartRenderer picks its extraction branch purely on entity.getBehavior(), which is public and non-final, so a validation-only Minecart subclass returning a NewMinecartBehavior drives newExtractState and therefore MetalEntityObjectPose.minecartNewRender. The behavior's physics never run: the driver pins position and rotation every frame regardless. What this does not cover is the feature-flag plumbing that would select the behavior in a real world, and the subclass asserts its own behavior type at spawn so the scenario cannot silently degrade into the old path. The new path also turns out to be the most reproducible of the six. With no lerp steps queued cartHasPosRotLerp() is false, so newExtractState reads getXRot/getYRot with no partialTick term at all, and unlike the rail-sampled path it uses the cart's own yaw — so the scenario just turns it, 6 degrees a frame, and leaves the hurt shake at zero. The shake is already covered by minecart_rail and is the one term that would put a wall-clock component back in. minecart_new occupies frames 216-227 with its capture at 224; expected captures 15 -> 16. Compiles and the 112 unit tests pass; still not run-verified, as the validation client remains occupied by another session.

This is that transform and its identity, which is the part that can be built and tested from this line. Attaching the sample still needs an entry point in MetalFxManager and remains recorded, not done. Read out of PistonHeadRenderer.submit rather than assumed, and the shape is not symmetric: poseStack.translate(xOffset, yOffset, zOffset); submitMovingBlock(..., state.block, ...); poseStack.popPose(); if (state.base != null) submitMovingBlock(..., state.base, ...); The base is submitted after the pop, so the travelling head carries the progress-interpolated offset and the piston body does not. Handing the body the head's transform would drag a stationary block across every generated frame, which is worse than giving it no motion at all. LevelRenderer.submitBlockEntities translates by blockPos - cameraPos before dispatching, so world space is the block position plus that offset for the head and the bare block position for the base. Identity comes from the block position, not from any object. BlockEntityRenderDispatcher calls createRenderState every frame, so the render state and the two MovingBlockRenderStates hanging off it are new each frame and cannot carry history; the block entity does not move, so its position is the stable part. The packed position is run through a SplitMix64 finalizer because BlockPos.asLong concentrates entropy in the low bits and this id shares a key space with the entity path's UUID-derived ids. A per-part salt keeps a piston's two blocks from sharing one history. Signatures take the fields rather than PistonHeadRenderState, which initialises a field from BlockEntityTypes and so cannot be constructed without a registry. The thin overload that does take the render state is kept even though its caller does not exist yet: it makes the compiler check the field names, so a Minecraft rename breaks the build instead of the frame. Eight tests, asserting the delta the interpolator consumes rather than the absolute matrices. Two are there to catch a test that would otherwise pass vacuously: the stationary-base case also asserts the head did move, and the idle-head case asserts a paused piston gets no velocity. One asserts a NaN offset stays visible to MetalMotionStateStore's finite check instead of being quietly replaced by identity. 120 tests pass.

Gradle's Exec task has no notion of 77 — it fails on any nonzero exit, and no task in this build sets ignoreExitValue — so on a Mac older than 26 the build failed with a message that said SKIPPED. Both tasks that run the binary, metalFrameGenerationPresentationValidation and metal4PresentValidation, guarded only on isMacOsX(), which does not check the version. check dependsOn the first of them and build dependsOn check, and the release workflow runs `./gradlew buildMacNative build` on a macos-15 runner, so this was reachable on a v* tag push rather than purely hypothetical. Gate the macOS version in onlyIf rather than mapping 77 to exit 0. A skipped task is reported by Gradle as SKIPPED; a zero exit would be reported as a task that ran and passed while validating nothing, which is the failure mode the run-state gate in 5ff9fa1 exists to prevent. An os.version that does not parse is treated as unknown rather than old, so a capable host is never silently skipped; the binary's own @available guard remains the backstop. The Swift is left alone: nothing consumes exit 77 (no CI script or wrapper reads it), and it stays a meaningful signal for running the harness directly. Verified by overriding os.version for the build JVM: at 15.0 both tasks report `Task :... SKIPPED` with the reason and the build succeeds where it previously failed.

So the barrier map's consumer barriers can be *appended* to the existing encoders rather than replacing anything. Synchronization layer: this adds ordering to the Metal 3 path and removes none. No fence is touched. Appending can only strengthen ordering, which is exactly why it is a usable test: output must stay byte-identical, and if it does not, the stage pair in the barrier map is wrong. Discovering that here costs one test run; discovering it in M7e costs a random glitch with the fences already gone and nothing left to compare against. Switch metallum.opt.metal4Barrier, default off, and deliberately independent of the metal4 master gate - this API is gated on the OS version rather than on MTLGPUFamily.metal4, the same as the residency set in M3. Wired at all 13 consumer positions from the map, including both encoders that have no fence at all under Metal 3 (E7 metallum_metalfx_mark_transparency and E10 the historyBlit in encode_motion_v2). So this also tests whether supplying the missing edges changes the picture. Stage masks are passed as raw UInt bits through a small private enum, so the 13 call sites need no #available each - MTLStages is a macOS 26 symbol and cannot appear in an unversioned signature. Bit values verified against MTLCommandEncoder.h. Evidence, in metal4PipelinePathTest under MTL_DEBUG_LAYER: the shipping export metallum_encode_texture_copy (edge E11) is driven four times - switch off and on, each with and without the existing fence - and the output is byte-identical every time, with the colour correct. That is the golden-frame argument at test scale. Two findings while doing it: - MTLStages.rawValue is UInt, not UInt64, while the Java ABI passes long. M7e will need an explicit conversion at the boundary. - The real encoder-factory count is 16 calls in MetallumNative.swift, with zero in the other two native files. An earlier count of 18 included two @_cdecl signature lines rather than calls; the map's 17 rows are those 16 plus the MetalFX-internal scaler.fence row. A claimed 22 is not reproducible in this tree. The golden-frame run itself could not be executed, and the reason is worth reading in the audit: minecraftMetalFxClientValidation is currently hard-red for everyone for a reason unrelated to Metal. It dies during mixin transformation, before the window exists ("Window size: "), on a fabric-renderer-api-v1 injection check against MovingBlockFeatureRenderer. Two clean runs, one with the new switch and one without, fail identically, so it is neither this change nor the cutout items nor the headless environment. Every acceptance gated on L3 across the audit is blocked until the Fabric API mixin incompatibility is resolved; recorded as a recommended P0 with the prior "L3 is red because of the in-flight cutout work" assumption corrected. Verification, all green: compileJava, compileTestJava, test, buildMacNative, buildIOSNative, metalMrtSmokeTest, metal4PipelineSmokeTest, metal4PipelinePathTest and metalFrameGenerationLifecycleTest (9).

`spektrafilm-main`,因此整晚没收到协作协议通知,一直直接写集成 checkout。在途改动已按要求导出为补丁并把共享树恢复干净。**本文只写代码和 git 里读不出来的东西**。 + +--- + +## 1. cutout 判据演进到哪一步,为什么是这个形状 + +### 1.1 病因只有一个:`reactive` 抑制本身 + +reactive 越高 → 时域累积越少 → 而正是时域累积在重建抖动采样下的亚像素覆盖。所以给 alpha-test 内容写高 reactive 去"保护"它,**恰恰制造了它要防的抖动**。FSR2 文档明说接近 1.0 的值不会有好结果。 + +这个病因今晚在**三个不同的写入者**里各犯了一次,而且每修好一层,下一层才浮上来当主导——这是最重要的一条经验:**不要以为修完一处就完了,要去测"现在是谁在主导"**。 + +| 层 | 写入者 | 修之前占轮廓带 | 处理 | +|---|---|---|---| +| a | cutout dilation kernel 铺满整片树叶 = 1.0 | — | 边缘带 + 内部 0.0 | +| c | `metallum_motion_merge_v2` 的 `if (disocclusion > 0.5) reactive = 1.0` | 98%+ | 3×3 深度膨胀 + cap 0.85 → **降到 0.6%** | +| d | depth-edge 启发式饱和到 cap | **98.5%** | cap 0.5 → 0.25,边缘带 0.35 → 0.20 | + +第 c 层的机制值得记住:重投影用单点最近邻 `uint2(previousPixel)`,亚像素抖动让这个探针在轮廓两侧逐帧来回跳;叶片深度(~0.01)对天空(0.00002)的差恒大于 `max(0.0025, |d|*0.01)` 阈值,于是**一个完全静止的轮廓被隔帧判成 disocclusion**,历史每隔一帧丢一次。 + +### 1.2 定量规律(这条是判据形状的依据) + +写入者之间用 `max()` 合成,所以轮廓带实际拿到的是 `max(cutoutReactiveEdgeWeight, depthEdgeReactiveCap)`。扫描这个值: + +|

coverage→dilate→reactive=1.0 「修复」** — 已证伪。它是病因不是解药。用户在 2026-07-26 明确反馈没有效果,由此才重新诊断。 +2. **只改 cutout 侧、不动天空侧** — 无效。轮廓重建需要边界**两侧**都有可用历史;天空侧被 `reactive=1.0` + `disocclusion=1.0` 每帧清空,cutout 侧再怎么调都没用。 +3. **把藤蔓当成独立问题** — 否决。用 JDK 25 的 `javap` 反编译 `DefaultTerrainRenderPasses.class` 确认 Sodium 0.9 只有 SOLID / CUTOUT(discard) / TRANSLUCENT 三个 pass,藤蔓已经在 CUTOUT 内,和树叶同一套策略。它更抖只是因为 1–2 px 宽的细条几乎 100% 是边缘带且背景是天空。 +4. **怀疑 §14 的 sky far-plane motion 让天空自己变抖** — 否决,实测方向相反。隔离 A/B(两臂 mask 逐字节相同):开阔天空 0.1490 → 0.0829,两臂 p95 **都是 0**。天空渐变本身是稳的。 +5. **把 depthEdgeReactiveCap 降到 edge 权重以下** — 无额外收益,`max()` 会把主导权交回 edge band。想继续降必须两个一起降。 +6. **用 4 次全量客户端跑做因果扫描** — 低效(每次约 4 分钟)。改用 §1.3 的读回+分桶,一次跑定位主导者,再针对性扫描。 +7. **把工作树拷到 scratch 目录做隔离** — 失败,而且**误导了我一小时**。拷贝本身没问题,是拷到了一个已经被 `options.txt` 改坏的状态(见 §4.1),我据此误判成"隔离副本坏了"。教训:先验证基线能跑 Metal,再归因。 +8. **transparency mask 改成 alpha 正比(`clamp(coverage) * value` 取代二值)** — **保留疑虑,未验证**。理由是 FSR2 的 "write the alpha" 指导,但云/天气/粒子**没有运动矢量**,按 alpha 降低它们的 reactive 会让它们落到无法重投影的历史上。用户报告过云边缘抖动,时间点和这个改动吻合。harness 强制 `cloudStatus(OFF)`,所以从未测到。**这是我最不放心的一处改动。** + +--- + +## 3. 验证门的真实状态(哪些红不是你的) + +- **`minecraftMetalFxClientValidation` 必红,与 cutout

`cutout_grass_hold` 上都会测成 **bit-for-bit no-op**。§14 的 sky far-plane 改动就是这么被误判成"无效"的(0.636798 → 0.636861)。天空相关的东西必须用 `cutout_sky_hold`(frame 118 开顶,棋盘格树叶 + 独立渲染藤蔓,相机 −50°)。 + +flicker JSON 里的

What the measured points say: - The knobs saturate and are near-interchangeable. Once the edge weight is at 0.20, the depth-edge cap contributes nothing (2.6998 -> 2.7020 for 0.5 -> 0.25). - Only the exact-zero corner releases the band: 0.4039 mean / p95 1, against ~2.7 for every arm with any nonzero band reactivity. A plateau with a cliff, not a slope, so intermediate settings must not be extrapolated. - §15.8's residual is closed: it was the band. 0.4039 against a 0.0801 control. Also records a defect in the acceptance itself. EDGE_REACTIVE_MIN is 72 (0.282), so cutoutEdgeBandReactivePixels reads 62,802 at the 0.35 default but exactly 93 at 0.20, 0.10 and 0.00 alike — those 93 come from the disocclusion cap, not the band. The assertion is therefore vacuous below 0.282 and any default change into that range has to lower the threshold in the same commit. The threshold is left alone here because the default is unchanged. Separately, warn once when the CUTOUT reactive pipeline is substituted: it is namespaced metallum, and shader-pack overrides that match on a sodium namespace (Iris' isSodiumPipeline) skip it silently. Unreachable while MetalFxConfig defaults to Mode.OFF; fires as soon as Temporal is enabled. Note for the merge: a parallel session's in-flight patch carries a different §16 under the same number. Same data, different reading of whether to move the defaults now. Needs arbitration before both land.

Arms +`probe3`–`eb010` were run by the preceding session; `eb020r` and `zero` are the +two combined arms it never landed. + +| arm | `depthEdgeReactiveCap` | `cutoutReactiveEdgeWeight` | skyEdgeMean | P95 | maskMean | control | +|---|---|---|---|---|---|---| +| probe3 | 0.5 (default) | 0.35 (default) | 5.0099 | 17 | 2.5262 | 0.1888 | +| dc025 | 0.25 | 0.35 | 3.6094 | 12 | 1.9468 | 0.1448 | +| dc010 | 0.10 | 0.35 | 3.6062 | 12 | 1.9455 | 0.1151 | +| dc000 | 0.00 | 0.35 | 3.5962 | 12 | 1.9358 | 0.0900 | +| eb020 | 0.5 | 0.20 | 2.6998 | 9 | 1.4082 | 0.1414 | +| eb010 | 0.5 | 0.10 | 2.6744 | 9 | 1.2913 | 0.1398 | +| **eb020r** | **0.25** | **0.20** | **2.7020** | **9** | **1.4093** | **0.1415** | +| **zero** | **0.00** | **0.00** | **0.4039** | **1** | **0.2791** | **0.0801** | + +### 16.3 What the sweep says + +1. **The two knobs are not additive; they are nearly interchangeable, and both + saturate immediately.** Holding edge at 0.35, dropping the cap 0.5→0.25 buys + −28% and then nothing (0.25→0.10→0.00 moves the mean by 0.013). Holding the + cap at 0.5, dropping edge 0.35→0.20 buys −46% and then nothing. `eb020r` + (0.25 + 0.20) lands at 2.7020 against `eb020`'s (0.5 + 0.20) 2.6998 — a 0.08% + difference, i.e. the cap contributes nothing once the edge weight is down. + **Lowering either knob below its saturation point is wasted range.** +2. **Only the exact-zero corner releases the band.** Every arm with any nonzero + reactivity on the silhouette sits at 2.7–5.0; `zero` drops to 0.4039 with P95 + 1. The magnitude of a nonzero reactive value barely matters — its *presence* + costs roughly 2.3 units of flicker. This is consistent with Apple's stated + semantics (>0 biases toward the current frame) being sharply nonlinear near 0, + and it is why the earlier single-knob arms all plateaued. +3. **§15.8's undecomposed residual is now decomposed.** The band's floor is + 0.4039 against a same-scene control of 0.0801 — 5×, not the ~30× recorded in + §15.8. The residual was the reactive edge band itself, not an unexplained + term. +4. **The response is not linear, so it must not be extrapolated.** A parallel + analysis of the same arms proposed a linear law and predicted further material + gains at (0.10, 0.10), with the zero point extrapolated rather than measured — + three attempts to measure it were lost to the §16.1 startup crash. The + measured points refute a linear reading: 0.20→0.10 on the edge weight moves + the mean by 0.9% (2.6998→2.6744) and 0.5→0.25 on the cap moves it by 0.08% + (2.6998→2.7020), while (0, 0) drops 85%. The shape is a plateau with a cliff + at exactly zero, not a slope. Any predicted intermediate gain between 0.20 and + 0.00 is an artifact of fitting a line to a step. + +### 16.4 Why this does not simply become the new default + +`zero` is the best flicker number available and the worst ghosting posture +available: it removes the anti-ghosting band this remediation deliberately kept +(§4, §13). The harness measures a **static hold** and therefore cannot see +ghosting at all — it has no arm in which the trade is visible. Picking the +default is exactly acceptance criterion §11(5), the in-game strafe-past-a-tree +check, and it stays a human step. What the sweep does settle is the *shape* of +the choice: + +- Anything in 0.10–0.35 for the edge weight is within 1% of the same flicker, so + **prefer the high end of that range** — it is free protection. +- `depthEdgeReactiveCap` below 0.25 is inert; leave it at 0.25–0.5. +- The only decision with real flicker consequence is **band or no band**. + +Recommendation, pending §11(5): keep the current defaults (0.5 / 0.35) or move to +(0.25 / 0.20) — the latter is −46% flicker for a band that is still 0.20 wide. +Do not ship `zero` without the in-game ghosting check. + +### 16.5 The CUTOUT acceptance criteria were never the blocker + +Both L3 runs pass `cutout_leaves` and `cutout_grass` at every knob setting +tested, including `zero`: + +| scenario | coverage px | interior px | interior violations | edge-band reactive px | +|---|---|---|---|---| +| `cutout_leaves` | 87,581 | 51,712 | 0 | 93 | +| `cutout_grass` | 72,370 | 51,347 | 0 | 24 | + +They pass at every setting, but for a reason that has to be stated plainly, +because it is a defect in the assertion rather than a property of the code. Per +arm, on `cutout_leaves`: + +| arm | edgeWeight | cap | `cutoutEdgeBandReactivePixels` | +|---|---|---|---| +| probe3 | 0.35 | 0.5 | 62,802 | +| dc000 | 0.35 | 0.00 | 62,802 | +| eb020 | 0.20 | 0.5 | 93 | +| eb020r | 0.20 | 0.25 | 93 | +| zero | 0.00 | 0.00 | 93 | + +`EDGE_REACTIVE_MIN` is 72, i.e. 0.282 in normalized terms. An edge weight of 0.35 +writes 89/255 and clears it; 0.20 writes 51/255 and does not. So the count +collapses from 62,802 to 93 the moment the weight crosses that threshold — and +those 93 are then **identical at 0.20, at 0.10 and at 0.00**, because they are +supplied by the disocclusion cap (0.85 = 217/255, §15.5), not by the band. + +Consequence: `cutoutEdgeBandReactivePixels > 0` is a real assertion at today's +0.35 default and a **vacuous** one at any weight below 0.282 — it would pass with +the band switched off entirely. `depthEdgeReactiveCap` never contributes to it at +all (dc000 at cap 0.0 still reports 62,802). **Any change of the default edge +weight below 0.282 must lower `EDGE_REACTIVE_MIN` in the same commit**, or the +invariant silently stops testing the thing it was written to test. + +The interior-violation half of the contract is unaffected — it is a +`reactive > 48` test on interior pixels and stays meaningful across the range. + +The gate's two red scenarios are `item_spin` and `minecart_rail`, both owned by +the object-motion line, and both failing only `OBJECT_MIN_SPIN_SPREAD_X = 0.008`: +`item_spin` measures X-spread 0.004677 (Y 0.0078125), `minecart_rail` measures +[0.001292, 0.007355]. Both are marginal misses against a floor introduced by +`5504828`. **The S9B/C and S10 enabled-state acceptance is therefore not blocked +on this line.** ## 13.

Add bounded, +low-overhead timing around major native passes, or capture a Metal System Trace: + +- Sodium terrain solid / cutout / translucent +- entities and particles +- world depth preservation (must be absent when MetalFX is OFF) +- post-processing and GUI +- texture uploads and command-buffer idle gaps +- encoder transitions, fence waits, and drawable wait + +Run at least the controlled validation room plus one representative real world. +Record CPU encode time separately from GPU execution. The native baseline has +about 2.78 ms between GPU p95 (7.04) and frame-interval p95 (9.82), so CPU, +submission, or pacing work is material even before GPU shader optimization. + +### P0: verify OFF truly removes all MetalFX work + +Trace the OFF branch from `MetalFxManager.beginFrame/endUpscale` through the +main renderer and confirm no motion, reactive, world-depth snapshot, scene copy, +or private MetalFX texture allocation survives. Add counters/assertions to the +native baseline artifact rather than relying on configuration text alone. + +### P1: finish main-render Metal 4 migration only from the barrier map + +Read `docs/metal4-barrier-map.md` before editing. It records two existing Metal 3 +race edges and explains why the six MetalFX exports need MTL4 twins. The likely +payoff is lower CPU encoding/submission overhead and explicit residency/barrier +control; do not promise lower fragment cost without measurement. + +Suggested staged order: + +1. Measure Metal 3 main-queue CPU encode and GPU time. +2. Implement the smallest MTL4 main command-buffer path with kill switches. +3. Preserve Metal 3 fallback and pixel/readback parity. +4. Enable API/GPU validation for the new barrier path. +5. A/B the same 240-frame native OFF scene and a real world. + +### P1: inspect bandwidth and overdraw before shader micro-optimization + +At 3024 x 1734, full-screen RGBA8 read+write traffic is roughly 40 MiB per pass. +Audit unnecessary resolve/copy/clear/load-store actions, full-screen post passes, +and translucent/cutout overdraw. The removed native-direct copy saved only about +0.31 ms under real paired contention, so each proposed pass removal must be +measured rather than estimated. + +### P2: separate renderer optimization from FrameGen contention + +The native OFF source GPU p95 is 7.04 ms; enabling the full-resolution motion +pipeline plus FrameGen raises source GPU p95 to 12.40 ms. Do not label the +difference as ordinary native-render cost. Profile these independently: + +- native renderer only +- native renderer + motion production, no generated present +- native renderer + motion + generated present + +The full-resolution camera/disocclusion/merge path and later depth/motion +resampling are strong optimization candidates. A future direct-FG path should +produce bounded-resolution motion inputs directly where correctness permits, +instead of producing all auxiliary textures at 3024 x 1734 and downsampling. + +## Immediate next commands + +Use the Minecraft Java 25 runtime: + +```bash +export JAVA_HOME='/path/to/a/JDK-25/Contents/Home' +``` + +First inspect the unverified tail of the current Gradle change: + +```bash +git diff --check +git diff -- build.gradle +./gradlew compileJava buildMacNative tasks --no-daemon +``` + +Then preserve the current native baseline before adding instrumentation. Do not +overwrite it with a differently configured run. Prefer a new output directory +or copy it into a dated benchmark directory with a manifest of JVM properties, +drawable size, world, view distance, commit, and dylib hash. + +Recommended new verification task name: + +```text +minecraftNativeRenderEfficiencyValidation +``` + +It should run MetalFX OFF, FrameGen OFF, Retina fullscreen, collect at least 240 +steady frames, emit pass-level CPU/GPU timings, and exit automatically. + +## Remaining broader goal work + +The original exact-half Temporal-to-native plus native FrameGen objective is not +complete. Native-resolution FrameGen itself previously cost 22-26 ms and cannot +meet 120 present on this M1 Pro. The bounded native-direct experiment is a viable +alternative, not a completed replacement. Fullscreen/resize/GUI/exit lifecycle, +HUD fields, timeline acceptance, shader-headroom proof, and Launcher QA deployment +remain open after the native renderer investigation. + +## 2026-07-28 continuation: measured main-render work + +The continuation added validation-only logical-pass CPU timings and native +render/blit encoder GPU timestamps. On this M1 Pro the counter set supports +stage-boundary sampling, so the GPU rows describe whole native encoders rather +than individual draws. Pass labels are retained when pass timing is enabled, +without enabling ordinary debug labels globally. + +Latest labeled baseline before the CPU lookup optimization, MetalFX OFF at +3024x1736: + +| Metric | Result | +| --- | ---: | +| Frame interval p50 / p95 | 8.331 / 9.804 ms | +| Main command-buffer GPU p50 / p95 | 6.602 / 7.164 ms | +| Main world render encoder GPU p95 | 6.204 ms | +| Entity-translucent render encoder GPU p95 | 0.399 ms | +| GUI-before-blur render encoder GPU p95 | 0.211 ms | + +The world work is already coalesced into one native encoder whose first logical +label is `Sky disc`; the data does not support blindly merging more world +passes.

Whole-command-buffer GPU p95 was 7.172 ms in the +confirmation run, effectively unchanged (+0.1%); frame-interval p95 was 9.681 ms +(-1.3%). Treat the exact CPU counts as the hard result and the short timing +deltas as controlled-scene evidence, not a universal speedup claim. + +Two kill-switch A/B experiments remain disabled by default: + +| Candidate | GPU p95 | Frame p95 | Decision | +| --- | ---: | ---: | --- | +| split fence | 7.515 ms (+4.9%) | 9.690 ms (-1.2%) | Reject for now: worse GPU tail | +| explicit Metal 3 residency | 6.255 ms (-12.8%) | 10.943 ms (+13.0%) | Inconclusive: frame tail regressed | + +The split-fence run used a drawable eight pixels taller than the first baseline; +the residency run matched the later 3024x1740 confirmation but had abnormally +slow world preparation. Neither result is strong enough to change defaults. + +## 2026-07-28 continuation: Metal 4 main-queue boundary + +The `metallum.opt.metal4MainQueuePilot` path is no longer an empty-command-buffer +smoke test. It now validates all of these on the real M1 Pro runtime: + +- three reusable `MTL4CommandBuffer` / `MTL4CommandAllocator` slots; +- a real `MTL4ComputeCommandEncoder` buffer copy on every submission; +- a queue-attached, committed and requested `MTLResidencySet` containing the + source and destination allocations; +- six `MTL4CommitFeedback` completions followed by byte-for-byte shared-buffer + readback validation. + +The log gate is: + +```text +Metal 4 main-queue pilot validated: 3 reusable buffers, 6 compute copies, explicit residency +``` + +This is a main-queue API/resource-lifecycle pilot only. The Java-driven Minecraft +render encoders still run on the Metal 3 command buffer, and the pilot does not +yet validate main-render argument tables, MetalFX MTL4 twin ABIs, the §1 encoder +barrier map, drawable presentation, or visual parity. Do not describe it as a +migrated Metal 4 renderer. + +## 2026-07-28 completion: Metal 4 main Minecraft renderer + +The statement immediately above describes the earlier pilot and is now +superseded for MetalFX OFF. The Java-driven Minecraft main renderer has a real, +opt-in Metal 4 backend behind `metallum.opt.metal4MainRenderer=true`. Metal 3 is +still the default and remains the fallback. + +Implemented and exercised on the real M1 Pro: + +- three reusable `MTL4CommandBuffer` / `MTL4CommandAllocator` slots with commit + feedback, completion state, GPU timestamps and semaphore signaling; +- dual-dispatch native bridge entry points, so the existing Java command ABI + selects `MTLCommandBuffer` or the opaque Metal 4 lease without changing its + callers; +- `MTL4RenderCommandEncoder` for direct, indexed, multi-draw, indirect and + triangle-fan draws, plus full/partial clear and deferred depth store; +- `MTL4ComputeCommandEncoder` for all former blit operations; +- separate per-slot vertex and fragment `MTL4ArgumentTable` instances, using + GPU addresses for buffers and resource IDs for textures/samplers; +- PSO-time fail-closed binding limits: 31 buffers, 16 sampled images/samplers, + 128 texel textures, and vertex buffer slots no higher than 30; +- a persistent global residency set for every created buffer/texture, the + layer residency set for drawables, locked add/remove/commit, and deferred + removal through the existing destruction queue; +- consumer `.device` barriers at render/compute encoder creation according to + `docs/metal4-barrier-map.md`; the Metal 4 path ignores the old Java fence + calls while the Metal 3 path keeps them unchanged; +- queue-level drawable ordering: `waitForDrawable`, commit, + `signalDrawable`, then `present`. + +### MetalFX ABI compatibility boundary + +The six MetalFX native exports still accept `MTLCommandBuffer`, not +`MTL4CommandBuffer`. Passing a Metal 4 lease to them would issue Metal 3 +selectors on an incompatible object and crash. `MetalDevice` therefore engages +the Metal 4 main renderer only when MetalFX mode is OFF. If Spatial or Temporal +is active, it logs the fallback and retains the Metal 3 main queue. This is ABI +compatibility and crash prevention, not a claim that MetalFX compute/scaler +encoders have migrated to Metal 4. + +The fallback was run with both Metal 4 switches requested. Temporal initialized, +the log reported `mainRenderer=false`, and all 16 expected GPU attachment +readbacks passed with zero failures. A full MetalFX-to-Metal-4 migration remains +a separate follow-up requiring MTL4 twins for those exports and their internal +argument tables, residency and barriers. + +### Main-render runtime/readback validation + +`minecraftNativeRenderEfficiencyValidation` now schedules a bounded 256x256 +GPU-to-CPU readback of the real main color texture on timeline frame 16, before +the measured frame window begins at frame 61. The task fails unless the image is +nonblack, nonconstant, alpha-valid, and the requested Metal 4 backend reports +engaged residency plus command-buffer reuse. + +Latest Metal 4 readback: + +| Field | Result | +| --- | ---: | +| Pixels | 65,536 | +| Nonzero RGB pixels | 65,536 | +| Pixels differing from the first RGB value | 65,142 | +| FNV-1a 64 | `f08f3cdc98ccf6d6` | +| Validation | passed | + +The same readback also passed with Metal 3. Independent launches are not +byte-stable: two Metal 3 captures differed in 24.2% of pixels (SSIM 0.9537, +PSNR 36.50 dB), while the first Metal 3/Metal 4 comparison differed in 40.1% +(SSIM 0.9059, PSNR 32.43 dB). Visual inspection shows matching geometry, +occlusion and material structure with low-amplitude color/lighting differences. +This proves a real, structured readback and perceptual parity, not byte-exact +golden parity; do not strengthen that claim without an in-process deterministic +golden harness. + +The final Metal 4 readback run also completed all 240 measured frame intervals +and 240 GPU samples under Metal API Validation with no validation errors or GPU +faults. + +### Quantified efficiency result + +All rows below are the controlled Retina fullscreen room at 3024x1734 or +3024x1740, MetalFX OFF, with 240 measured frame intervals and GPU command +buffers.

A successful raw-frame capture or headless CI run +alone must not be called full BSL adaptation. diff --git a/src/main/java/com/metallum/client/metal/render/IrisMetalCenterDepthSampler.java b/src/main/java/com/metallum/client/metal/render/IrisMetalCenterDepthSampler.java new file mode 100644 index 000000000..9a2d04224 --- /dev/null +++ b/src/main/java/com/metallum/client/metal/render/IrisMetalCenterDepthSampler.java @@ -0,0 +1,261 @@ +package com.metallum.client.metal.render; + +import com.mojang.blaze3d.GpuFormat; +import com.mojang.blaze3d.PrimitiveTopology; +import com.mojang.blaze3d.buffers.GpuBuffer; +import com.mojang.blaze3d.pipeline.BindGroupLayout; +import com.mojang.blaze3d.pipeline.ColorTargetState; +import com.mojang.blaze3d.pipeline.CompiledRenderPipeline; +import com.mojang.blaze3d.pipeline.RenderPipeline; +import com.mojang.blaze3d.shaders.ShaderSource; +import com.mojang.blaze3d.shaders.ShaderType; +import com.mojang.blaze3d.shaders.UniformType; +import com.mojang.blaze3d.systems.RenderPass; +import com.mojang.blaze3d.systems.RenderPassDescriptor; +import com.mojang.blaze3d.textures.AddressMode; +import com.mojang.blaze3d.textures.FilterMode; +import com.mojang.blaze3d.textures.GpuTexture; +import com.mojang.blaze3d.textures.GpuTextureView; +import net.fabricmc.api.EnvType; +import net.fabricmc.api.Environment; +import net.minecraft.resources.Identifier; + +import java.nio.ByteBuffer; +import java.nio.ByteOrder; +import java.util.Objects; +import java.util.Optional; +import java.util.OptionalDouble; + +/** Metal implementation of Iris's temporally smoothed center-depth sampler. */ +@Environment(EnvType.CLIENT) +final class IrisMetalCenterDepthSampler implements AutoCloseable { + static final String SAMPLER_NAME = "iris_centerDepthSmooth"; + + private static final double LN2 = Math.log(2.0); + private static final int PARAMETER_BYTES = 16; + private static final int TEXTURE_USAGE = GpuTexture.USAGE_RENDER_ATTACHMENT + | GpuTexture.USAGE_TEXTURE_BINDING + | GpuTexture.USAGE_COPY_SRC + | GpuTexture.USAGE_COPY_DST; + private static final String VERTEX_SOURCE = """ + #version 450 + void main() { + vec2 positions[3] = vec2[]( + vec2(-1.0, -1.0), + vec2( 3.0, -1.0), + vec2(-1.0, 3.0) + ); + gl_Position = vec4(positions[gl_VertexIndex], 0.0, 1.0); + } + """; + private static final String FRAGMENT_SOURCE = """ + #version 450 + layout(std140) uniform CenterDepthParameters { + float lastFrameTime; + float decay; + vec2 padding; + }; + uniform sampler2D depth; + uniform sampler2D altDepth; + layout(location = 0) out float iris_fragColor; + + void main() { + float currentDepth = texture(depth, vec2(0.5)).r; + float weight = 1.0 - exp(-decay * lastFrameTime); + float oldDepth = texture(altDepth, vec2(0.5)).r; + if (isnan(oldDepth)) { + oldDepth = currentDepth; + } + iris_fragColor = mix(oldDepth, currentDepth, weight); + } + """; + + private final MetalDevice device; + private final MetalGpuTexture currentTexture; + private final MetalGpuTexture historyTexture; + private final MetalGpuTextureView currentView; + private final MetalGpuTextureView historyView; + private final MetalGpuSampler sampler; + private final GpuBuffer parameters; + private final ByteBuffer parameterStaging; + private final RenderPipeline pipeline; + private final float decay; + private boolean closed; + + /** + * Mirrors Iris 1.11.2's {@code CenterDepthSampler} at commit + * {@code 20e226b14fd2c3ba192e16ae2c8af4a27987767c}.

Inactive/shaders-off and non-owned pipelines remain unchanged. A focused real-MTLDevice rejection test plus fresh Potato reload and BSL HIGH physical regressions pass at `build/iris-runtime/core-semantics-strict-admission-20260731`. Unsupported post/compute/resource declarations already fail admission. | | Pack selection, profiles, boolean/slider options | Connected | Exact Iris bytecode shows option queue → `Iris.reload()` → rebuilt `ShaderPack/ProgramSet`; BSL HIGH generation 1→2 observed. Add a synthetic option-change conformance fixture so changed source/directives are asserted directly. | -| Dimension `ProgramSet`, fallback and program selection | Connected | Metal receives Iris's exact dimension `ProgramSet` and uses `ProgramFallbackResolver`.

The full Iris `ShaderKey`/RenderType catalog has not yet been exercised by one synthetic fixture. | +| Dimension `ProgramSet`, fallback and program selection | Connected | Metal receives Iris's exact dimension `ProgramSet` and uses `ProgramFallbackResolver`. Fixed Iris caches one pipeline per dimension; Metal now retains those generations independently, selects the returned cached generation, and publishes a newly prepared generation only after all constructor resources are complete. A failed candidate is retired without displacing the selected dimension. Nether/End live transitions are still the earliest content/runtime gate. See `build/iris-runtime/core-semantics-lifecycle-compute-order-20260731`. | +| Reload, disable-enable, resize and resource retirement | Connected | A fresh post-exact Potato Gate A run destroys generation 2, rebuilds generation 3 on `Iris.reload()`, and retains stable visible output with normal atlas animation; the accepted BSL reload also remains evidence. Generation-scoped cache/target/uniform teardown is implemented, cached dimensions coexist, and runtime disable after an active semantic generation enters fixed Iris's CPU-only `setShadersDisabled` transition while startup shaders-off remains dormant. Full disable-enable and live resize/dimension recreation still need physical lifecycle receipts. See `build/iris-runtime/potato-regression-20260731-post-exact-reload` and `build/iris-runtime/core-semantics-lifecycle-compute-order-20260731`. | +| Sodium/core vertex ABI and generic attributes | Connected | The complete pinned Iris 1.11.2 main/shadow `IrisPipelines` identity map is compared against Metal, including dynamic hand/block-entity selection, and physical Mojang/Sodium vertex ABI plus generic constant attributes have focused coverage. Potato/BSL terrain and core PSOs compile and render. A content fixture still needs to visibly exercise every mapped RenderType family before this semantic family is Closed. | | GLSL preprocessing, patching, linking, varyings and fragment outputs | Connected | All active Potato/BSL vertex/fragment stages translate and create physical Metal PSOs; fragment outputs/MRT fail closed. Geometry and tessellation are gaps. | -| MRT, formats, depth/cull/viewport, blend/write masks | Connected | MRT and unwritten attachments have GPU readback; gbuffer/core per-target state is mapped.

Fixed Iris global and per-buffer post blend overrides lower to per-attachment Metal blend/write state, with exact content readback for global additive, per-target alpha blend and per-target disable. Logical three-channel Iris colortex/shadowcolor formats backed by Metal RGBA now use a generation-owned sampled view whose alpha swizzle is 1, matching OpenGL rather than leaking the physical alpha lane; a real-M1-Pro test writes physical alpha 0 and reads logical alpha 255. Main and shadow targets share exact R/RG/RGB/RGBA 8-bit and 16-bit SNORM lowering, with logical RGB SNORM using the same alpha-one sampled view. Unsupported physical formats remain fail-closed. Broader format/viewport content permutations remain before this family is wholly Closed. See `build/iris-runtime/core-semantics-logical-rgb-alpha-20260731`. | +| Built-in/custom uniforms, matrices, previous state, time, camera, alpha test | Connected | Real Iris `CommonUniforms`, pack custom-uniform graph and per-program alpha metadata feed std140 blocks. The complete fixed-Iris dynamic catalog (`entityId`, `atlasSize`, `gtextureId`, `textureReloadCount`, `gtextureSize`, `blendFunc`, `renderStage`) now materializes per draw from Iris captured state, real Metal texture views, stable logical texture identity and the pass blend contract; frame uploads deliberately omit these draw-owned bytes. Focused tests plus fresh Potato reload and BSL HIGH physical regressions pass at `build/iris-runtime/core-semantics-dynamic-uniforms-20260731`. A complete OpenGL/Metal uniform-value trace A/B is still missing, so this family is not yet Closed. | +| Sampled textures, aliases, noise/custom textures, filtering/wrap/mipmap | Connected; fixed-Iris overlay, typed-buffer and scalar raw-data surfaces closed; live aliases pending content gate | Render targets, depth, comparison samplers, PNG custom textures, noise and mipmaps have focused GPU coverage. The generic Iris external unit-1 overlay contract now prefers draw-local Mojang `Sampler1` and otherwise consumes the validated live same-device `GameRenderer` overlay view with clamp/linear sampling; invalid or absent resources remain a hard descriptor failure. Generation-owned Iris custom 2D images now have exact format admission, sampled/storage binding in compute and raster, clear, resize and retirement; non-2D or unrepresentable storage-image formats fail closed. Fixed Iris 1.11.2 injects only `CloudFaces` (`R8_SINT`) and Sodium `u_SectionTimeInfo` (`R32_SINT`) as `samplerBuffer`; both retain their source `RenderPipeline` typed layouts and have focused ABI coverage. A pack-only `samplerBuffer` declaration has no Iris supplier and fails admission rather than receiving an invented resource. Iris `RawData1D`, `RawData2D`, `RawDataRect` and `RawData3D` create native dimensioned textures with exact scalar conversion, 3D upload/readback and unnormalized rectangle sampling; packed sources, unrepresentable formats and rectangle repeat fail during prewarm. `LightmapMarker` and ordinary/PBR `ResourceData` now refresh Minecraft-owned views and samplers on every use, retain external ownership and fail on missing/stale/cross-device resources; PBR queues advance at the fixed-Iris frame boundary. Their production resource-manager content readback remains the earliest gap. See `build/iris-runtime/bsl-v1.0.3-overlay-fix-final`, `build/iris-runtime/core-semantics-compute-shadowcomp-20260731`, `build/iris-runtime/core-semantics-raster-storage-20260731`, `build/iris-runtime/core-semantics-raw-custom-textures-20260731` and `build/iris-runtime/core-semantics-live-texture-aliases-20260731`. | | Colortex ping-pong, clear/format/flip and depthtex0/1/2 | Closed for raster fixtures | Content-level target tests plus Potato/BSL runtime traces cover the active contracts. Broader format and lifecycle permutations remain regression work, not a known BSL/Potato failure. | -| Shadow raster, matrices, color/depth targets and compare sampling | Closed for BSL HIGH | BSL HIGH shadow terrain/entities/block entities and post sampling render visibly. Shadowcolor mipmaps and compute-driven shadow/shadowcomp variants remain gaps. | -| Deferred/composite/final raster ordering and visible contribution | Closed for Potato and BSL HIGH | Both accepted fixtures execute their active chains with real resources and visible output. Post compute and post blend variants remain gaps. | -| Compute, SSBO, storage image and barriers | Gap at Iris integration | Native Metal backend primitives and GPU readbacks exist, but Iris post-chain resource construction/execution is not connected; capability negotiation intentionally reports unsupported. | -| Sky/cloud/horizon/weather/particles/entities/block entities/hand/water/glint/text routing | Connected | Potato and BSL close multiple real paths, including water/translucent MRT and direct core routing. A catalog-driven synthetic stage fixture is still needed for exhaustive coverage. | +| Shadow raster, matrices, color/depth targets and compare sampling | Partial; selected BSL HIGH raster and published overlay crash boundaries closed | The accepted BSL HIGH overworld raster fixture closes visible shadow terrain/entities/block entities and post sampling, including the repaired phase transition. A fresh HIGH run after the generic execution-graph changes reaches generation 2 and completes stable frame 160/220 readbacks without missing overlay, fallback, Metal fault, or the old phase error. Shadowcolor mip allocation/generation and standalone/shadowcomp compute+raster execution are connected, but no visible compute-shadow fixture has exercised them. Do not generalize these fixtures to all BSL options/content. See `build/iris-runtime/core-semantics-compute-shadowcomp-20260731`. | +| Deferred/composite/final raster ordering and visible contribution | Closed for Potato and BSL HIGH | Both accepted fixtures execute their active chains with real resources and visible output. Setup/Begin/Prepare and compute-only/compute+raster slots now share the fixed-Iris ordering model; post compute and blend variants still need conformance content readback. | +| Compute, SSBO, storage image and barriers | Connected; compute/raster storage ABI conformance closed | Iris setup/post/final/shadow/shadowcomp programs reach native Metal compute PSOs with reflected local sizes, absolute/relative/indirect dispatch, generation-owned static/relative SSBOs, custom 2D images, `colorimgN`/`shadowcolorimgN`, mipmaps and compute-to-raster fence ordering. A redistributable real-M1-Pro fixture performs compute-only and compute+raster writes, indirect dispatch, raster SSBO/storage-image writes, flip, resize and old-resource retirement with exact GPU readback. It now also verifies a second compute dispatch reading the first dispatch's storage-image write: default fixed-Iris serial mode uses a shared-fence encoder boundary per dispatch, while an explicit concurrent-compute directive retains an unsynchronized same-encoder group. Raster world/post/final/shadow programs bind the same global Iris SSBO and image ABI; missing resources fail closed. Fixed-Iris typed buffer samplers are inherited from the two source `RenderPipeline` layouts; arbitrary compute texel/storage-texel/atomic-counter declarations remain explicit admission failures. See `build/iris-runtime/core-semantics-compute-shadowcomp-20260731`, `build/iris-runtime/core-semantics-raster-storage-20260731` and `build/iris-runtime/core-semantics-lifecycle-compute-order-20260731`. | +| Sky/cloud/horizon/weather/particles/entities/block entities/hand/water/glint/text routing | Connected; catalog coverage incomplete | Potato and the accepted BSL fixtures close multiple real paths, including water/translucent MRT and direct core routing. Overlay-bearing vanilla ShaderKeys now preserve fixed Iris's external unit-1 contract across heterogeneous source layouts, while draw-local `Sampler1` retains precedence. A catalog-driven synthetic stage fixture remains necessary for exhaustive RenderType/ShaderKey coverage. | | Pack directives, feature flags and capability queries | Connected | Common renderer/target/shadow directives are consumed. Advanced flags are fail-closed while their executors are absent; they must be enabled only after semantic tests pass. | +| Color presentation and output color-space conversion | Connected; fixed-Iris non-sRGB conversion contract closed | Fixed Iris 1.11.2 performs its selected non-sRGB conversion after pack final rendering through an RGBA8 temporary texture, nearest sampling and copy-back, unless the pack declares color-correction ownership. Metal now generation-owns the same `DCI_P3`, `DISPLAY_P3`, `REC2020` and `ADOBE_RGB` passes using Iris's `/colorSpace.csh` math and fails admission for an incompatible MainTarget. A real-MTLDevice DCI-P3 readback changes RGB while preserving alpha; unchanged-build Potato reload and BSL HIGH regressions pass at 1708x960, with both pack-owned correction paths correctly bypassing the converter. A full OpenGL/Metal ramp differential from final colortex through drawable encoding remains the earliest broader presentation gap. See `build/iris-runtime/core-semantics-color-presentation-20260731-iter4`. | | MetalFX temporal scaler and frame generation handoff | Isolated; integration gap by design | Supported launch profiles are now separate: `runClientIris` forces MetalFX/FG/HUD off and `runClientMetalFx` keeps Iris semantic rendering dormant. The implicit combined `runClientAll` profile is removed and an offline task enforces those defaults. Preserve one jitter owner and add motion/reactive sidebands without replacing pack shaders before restoring a combined path. | -| Shaders-off vanilla/Sodium regression | Partial; exact final-frame difference remains | The deterministic real-client lanes now prove distinct physical game/log directories, identical world snapshots, fixed player identity and entity state, `VanillaRenderingPipeline`, no active pack/generation, and MetalFX/FG/HUD off. Exact comparison still fails: frame 160 differs at 5,253 of 6,558,720 bytes and frame 220 at 3,605 bytes (maximum channel delta 205, stable first offset 20,236). Do not loosen the gate; isolate the semantic bootstrap boundary after this preview release. See `non-iris-regression-gate.md` and `build/iris-runtime/non-iris-gate-20260730-deterministic-player`. | +| Shaders-off vanilla/Sodium regression | Closed for deterministic exact fixture | Fresh physical game/log clones use the same world snapshot, player/entity state, camera, clear-dusk clock, explicitly fixed real first-frame animated atlas input, `VanillaRenderingPipeline`, no active pack/generation, and MetalFX/FG/HUD off. Semantic-off and semantic-on raw MainTarget captures are byte identical at frames 160 and 220: 0 of 6,558,720 bytes differ, maximum delta 0, and all four frames share SHA-256 `acdc42d446814732c635b0d2c30c29e9721c072bc2d86ab9766e9705c43d2438`. The atlas input property is set only by this shaders-off task; active-pack comparisons retain normal animation. The exact verifier remains zero-tolerance.

Production pipeline admission is still fail-open. + `IrisPipelineFactoryMixin` catches `Throwable` and, unless the diagnostic + property `metallum.iris.strict=true` is set, returns + `VanillaRenderingPipeline`. A pack failure must instead reject activation or + retain the previous valid pipeline with a user-visible reason. +2. Uniform update semantics are not proven equivalent to Iris. + `IrisMetalUniformValues` performs global frame materialization, updates + unvisited fixed inputs through reflected private state, and advances history + outside the per-program update schedule. Previous/history initialization and + per-program frequency boundaries remain unresolved. +3. The validation Oracle must be isolated from production and must be proven + side-effect free. OpenGL trace mixins are still in the main Mixin manifest; + tracing must not call suppliers, `updateAll`, or any stateful update path. +4. There is no single clean, reproducible final artifact proving all gates. + Several accepted focused runs use older JARs or skipped compilation, and + the current tree includes unrelated MetalFX and user-owned changes. + +## Next implementation direction + +Work only in a new clean integration checkout or explicitly authorized copy, +starting from this HEAD and the ownership manifest. Apply changes in this +order: + +1. Split the ownership groups and rebuild one reproducible artifact. Do not + edit this frozen worktree as the integration target. +2. Replace default fail-open admission with a typed admission result. Active + pack failure must block generation activation or preserve the previous + valid generation; do not use a vanilla pipeline to represent successful pack + loading. Narrow catches to expected shader/admission/pipeline exceptions. +3. Move OpenGL trace and capture mixins into a validation-only source set/JAR. + Keep default `build`/`check` independent of attended WindowServer + presentation validation. +4. Rebuild the uniform Oracle from immutable cached values at the real + `ProgramUniforms.update()` and Metal staging-upload boundaries. Prove trace + on/off equality for frame bytes and supplier/update call counts before + changing production uniform code. +5. Model uniform ownership and scheduling per program, with explicit + tick/frame/draw/history-commit phases and a defined first-frame state. Do + not add more name-based matrix aliases. +6.

This makes a +missing or late readback a failed lifecycle event instead of an untracked +successful file write. Requests are bounded by maximum captures, pending +requests, capture payload bytes, artifact bytes, manifest bytes, and the +recorder's frame/pass/producer budgets. + +The `FINAL_DRAWABLE` path reads the source texture immediately before present. +Its metadata says `PRE_PRESENT_DRAWABLE_CONTENT`; it is not a claim about +WindowServer scanout, VRR, or display timing.

It is never replaced by a different pass and can be rejected by a +strict fixture. Encoder ordinals, object addresses, and shader-pack names are +not semantic IDs. + +Pipeline IDs are cached content-derived identifiers. They include the shader +stage material used by the compiled pipeline plus state inputs where the +existing pipeline exposes them. Metal 3/Metal 4 implementation labels belong +in metadata; they do not change semantic pass IDs. + +## Resource identity + +`ResourceIdentity` contains semantic name, runtime allocation ID, generation, +debug/native identity, format, dimensions, mip, sample count, and usage. The +stable key is for example: + +```text +colortex0@41 +colortex0@42 +``` + +The generation changes when a semantic resource is reallocated with a new +runtime identity or shape. It is never based only on a Java object address, +Swift pointer, or semantic name. + +## Expectations + +The expectation package contains five distinct contracts: + +- `ExactExpectation`: byte/texel equality with an optional byte mask. +- `NumericExpectation`: integer, FP16, FP32, depth, and HDR values with + absolute/relative tolerance, optional ULP tolerance, bounds, NaN/Inf policy, + mean, P95, P99, and maximum error. +- `InvariantExpectation`: executable rules such as finite motion, validity + masks, coverage, dimensions, and declared depth conventions. +- `ImageExpectation`: LDR per-channel comparison with alpha handling, + mismatch count, RMSE, PSNR, and SSIM metrics. New image contracts must + declare channel order (`RGBA`/`BGRA`), origin (`TOP_LEFT`/`BOTTOM_LEFT`), + and color space (`sRGB`/`linear`) when normalization is required. It is not + used as the core contract for motion, depth, validity, or reactive resources. +- `TemporalExpectation`: ordered prefix comparison after warmup, with finite + value checks and mean/P95/max frame deltas. + +Failure artifacts retain raw bytes and structured metrics.

Explicit +properties still override these defaults, but the shared artifact budget always +remains authoritative. `metallum.renderContract.maxManifestBytes` defaults to +64 MiB. Limits are per run, not a rolling quota, and rewrites are charged by +final file size. + +The cleanup task keeps at most two managed runs and 768 MiB in the system +temporary directory by default, removing runs older than twelve hours first. +Those limits can be changed with `-PrenderContractTempRetentionHours`, +`-PrenderContractTempMaxRuns`, and `-PrenderContractTempMaxBytes`. A failed +run is retained under `/tmp` until cleanup so its bounded evidence can be +inspected; a successful temporary run is removed after its completion gate. +Use `-PrenderContractPersist=true` or an explicit +`-Dmetallum.validation.output=/absolute/path` only when the artifacts need to +survive for analysis. Persistent output is never copied automatically. +The Minecraft validation task also runs the same bounded cleanup as a +post-run finalizer, including when the client exits with a failed expectation, +so older managed evidence is evicted without deleting the newest failure +report. + +Normal Minecraft contract validation records producer counts and type counts, +but omits per-producer bindings. Enable the expensive diagnostic evidence only +for a focused rerun: + +```sh +./gradlew renderContractMinecraftValidation \ + -Dmetallum.renderContract.captureProducers=true --no-daemon +``` + +The pass manifest marks this choice as `producerDetailsCaptured` and +`producerDetailsComplete`. When the first is `false`, an empty `producers` +array means "details were not captured", not "the pass had zero producers". +When the second is `false`, the records are a bounded diagnostic slice rather +than a complete producer trace. Pass-level producer counts remain comparable; +`compareProducers` fails closed with `producer comparison unavailable` until +both sides contain complete detailed records. + +Use a focused diagnostic rerun with: + +```text +-Dmetallum.renderContract.tracePass= +-Dmetallum.renderContract.captureProducers=true +-Dmetallum.renderContract.producerRange= +-Dmetallum.renderContract.maxDetailedProducers= +``` + +The current implementation records producer type, parameters, resource +binding summaries, written attachments, and the shared trace identity. It does +not yet automatically replay a Minecraft pass while scheduling GPU attachment +readbacks after every producer; producer-level localization is therefore a +bounded manifest/evidence capability, not a claim of complete automatic GPU +binary-search replay. + +For a persistent Minecraft diagnostic run, use the dedicated task. It enables +producer details by default and writes the outer validation artifacts to +`build/render-contract/minecraft-diagnose-current/`; the contract evidence is +under that directory's `render-contract/` child: + +```sh +./gradlew renderContractMinecraftDiagnose --no-daemon +``` + +Ordinary `renderContractMinecraftValidation` remains temporary unless +persistence is explicitly requested. This diagnostic task is the intentional +analysis escape hatch and is not enabled by ordinary gameplay or unit tests. + +Offline diagnosis compares two already persisted contract roots. Pass the +inner roots containing `pass-manifest.json` and `results.json`, not the outer +Minecraft directory: + +```sh +./gradlew renderContractDiagnose \ + -PrenderContractReference=/absolute/reference/render-contract \ + -PrenderContractActual=/absolute/actual/render-contract \ + -PrenderContractReport=/absolute/report.json --no-daemon +``` + +The task fails when either run is incomplete, even when all available raw bytes +happen to match. A failed capture parent is still mined for any raw +`actual.bin` that was successfully written, but the report labels the result +incomplete and cannot mark it passed. This separates useful forensic evidence +from a valid contract result. + +Golden files are never updated by a failed test. The explicit update command +requires both flags and copies the selected generated case into the fixture: + +```sh +./gradlew renderContractCase -PrenderContractCase=synthetic-mrt-basic \ + -PrenderContractPersist=true --no-daemon +./gradlew updateRenderContractGolden \ + -PrenderContractCase=synthetic-mrt-basic \ + -PconfirmGoldenUpdate=true -PrenderContractPersist=true --no-daemon +``` + +## First divergence workflow + +`PassManifestComparator.compare` finds the first logical pass whose manifest +differs. `compareCaptures` then compares ordered attachment samples and reports +the first pass, producer, resource, mismatch count, maximum error, mean error, +and P95 error. `compareProducers` performs the same localization within a +known pass, but fails closed when either manifest omitted producer details. +The final manifest has `manifestComplete=true` only after all open passes are +closed and the manifest itself has been written within budget. + +Capture comparison aligns by frame, semantic pass occurrence, producer index, +and stable resource key. Native sequence numbers are evidence, not the +long-term identity. Attachment contracts compare semantic resource name, +generation, format, dimensions, mip/sample state, usage, and load/store +actions; runtime object IDs and native pointers are deliberately not used for +cross-backend equality. + +For a costly real run, capture only `AFTER_PASS` first. Re-run the reported pass +with producer capture enabled and narrow the producer range until the report +contains `lastMatchingProducer` and `firstDivergentProducer`. The evidence +should include the producer type, pipeline/shader IDs, bindings, viewport, +scissor, blend/depth state metadata, and the previous/current attachment +artifacts. A "likely stage" is an inference and must not be presented as a +confirmed root cause. + +## Iris reference boundary + +`IrisReferencePassRegistry` registers program, pass index, and stage against a +semantic ID. It deliberately has no shader-pack-name branch. Reference runs +are represented by `ReferenceRun`, `ReferenceFrame`, `ReferencePass`, +`ReferenceAttachment`, and `ReferenceProducer` records. + +The capability result is one of: + +```text +SUPPORTED +SUPPORTED_WITH_DECLARED_DIFFERENCE +REJECTED_BEFORE_EXECUTION +UNCLASSIFIED +``` + +The current repository provides the registration boundary and synthetic +contract path. It does not yet claim a complete fixed-version +Iris/OpenGL-to-Metal replay or cross-backend parity for every shader pack. +Missing reference artifacts and unclassified strict passes are evidence of an +incomplete run, not a pass. + +## Metal 3 and Metal 4 + +`renderContractMetal3NativeTest` and `renderContractMetal4NativeTest` run the +same production Java -> FFM -> Swift native integration suites with separate +backend properties. `renderContractSyntheticValidation` additionally runs the +deterministic contract model for MRT, depth/occlusion, blend, viewport/scissor, +compute-to-render dependency, temporal prefix, and final composition, then +compares the Metal 3 and Metal 4 logical manifests. + +Native smoke success alone is not an expectation result. The task must produce +test results and the synthetic run must produce passed manifests and capture +results. + +## Minecraft completion gate + +`renderContractMinecraftValidation` enables the recorder only for that task. +The client writes contract counters into `run-state.json` and the Gradle +`runClient` gate requires: + +```text +timeline completed +expected GPU captures completed +no legacy metric failures +contract requested == completed captures +no pending/failed/dropped captures +no dropped trace events +logical pass count > 0 +pass manifest finalized +``` + +An absent or malformed run-state is a failure, even when Gradle itself exits +successfully. WindowServer, MetalFX private-kernel, GPU validation, and display +scanout limitations must be reported as skipped or environment failures, not +silently converted to a green result. + +## Commands + +Use the signed Homebrew JDK 25 on this machine: + +```sh +JAVA_HOME=/opt/homebrew/opt/openjdk@25/libexec/openjdk.jdk/Contents/Home \ +./gradlew renderContractUnitTest --no-daemon + +JAVA_HOME=/opt/homebrew/opt/openjdk@25/libexec/openjdk.jdk/Contents/Home \ +./gradlew renderContractNativeTest --no-daemon + +JAVA_HOME=/opt/homebrew/opt/openjdk@25/libexec/openjdk.jdk/Contents/Home \ +./gradlew renderContractSyntheticValidation --no-daemon + +JAVA_HOME=/opt/homebrew/opt/openjdk@25/libexec/openjdk.jdk/Contents/Home \ +./gradlew renderContractMinecraftValidation --no-daemon + +JAVA_HOME=/opt/homebrew/opt/openjdk@25/libexec/openjdk.jdk/Contents/Home \ +./gradlew renderContractValidation --no-daemon +``` + +`renderContractValidation` is the aggregate and includes ordinary tests, +native build, both Metal modes, synthetic validation, manifest validation, and +the windowed Minecraft validation.
