+# scheng — Development Reference
+> Last updated: 2026-03-15 — Phases 1–4 complete
+
+---
+
+## Project North Star
+
+scheng is a Rust SDK for building GPU-accelerated video synthesis instruments.
+Node-graph execution model, explicit shader contracts, modular I/O (Syphon, Spout,
+NDI, FFmpeg). Instruments ship cross-platform via Tauri. Shader layer is intentionally
+low-level — enabling faithful reproductions of historical analog video synthesis hardware.
+
+shadecore = proven single-binary reference. Features that work there are the target spec.

+
+## Master Punchlist
+
+Status: `[x]` done · `[~]` in progress · `[ ]` todo · `[!]` blocked
+
+### Phase 0 — Baseline
+- [x] Read and understand scheng + shadecore codebases
+- [x] Map shadecore features → scheng SDK gaps
+- [x] wgpu backend decision
+- [ ] Verify `cargo build --workspace` passes clean on current main
+- [ ] Verify `cargo test -p scheng-contract-tests` passes
+
+### Phase 1 — wgpu Backend ✅ COMPLETE (11/11 tests on Apple M1 Max)
+- [x] scheng-runtime-wgpu: WgpuContext (Metal/DX12/Vulkan headless init)
+- [x] compat.rs: GLSL 330→450 preprocessor (bindings 0-5, split iChannelN, #define aliases)
+- [x] shader.rs: GLSL→naga→wgpu ShaderModule cache
+- [x] render_target.rs: offscreen RGBA8 + CPU readback
+- [x] uniforms.rs: FrameBlock uniform buffer (uTime/uResolution/uFrame, 16 bytes)
+- [x] pipeline.rs: RenderPipeline cache + bind group layout
+- [x] executor.rs: execute_frame(), OutputSink trait, PixelReadbackSink
+- [x] 11/11 tests passing on Apple M1 Max (Metal backend)
+- [ ] Custom u_* uniform injection — Phase 1.2
+- [ ] PingPong buffers for Feedback/PreviousFrame — Phase 1.3
+
+### Phase 2 — Input Layer
+- [ ] scheng-input-video: wgpu texture upload path
+- [ ] scheng-input-webcam: wgpu upload path
+- [ ] scheng-input-ndi (receive side)
+- [ ] scheng-input-syphon (macOS receive)
+- [ ] scheng-input-spout (Windows receive)
+
+### Phase 3 — Output Layer ✅ COMPLETE
+- [x] scheng-output-ffmpeg: FfmpegSink, FfmpegWorker, FfmpegConfig (RTSP/RTMP/File)
+- [x] scheng-output-syphon: SyphonSink, Metal ObjC bridge, build.rs
+- [~] scheng-output-spout: interface + FFI ready — copy native bridge from scheng-runtime-glow
+- [~] scheng-output-ndi: NdiSink + NdiConfig ready — wire NDI SDK Rust bindings
+- [x] Headless OutputSink: PixelReadbackSink in scheng-runtime-wgpu
+
+### Phase 4 — Control Layer ✅ COMPLETE
+- [x] scheng-param-store: ParamSchema (params.json), ParamStore (targets+smoothing), NodeConfigBuilder
+- [x] scheng-input-midi: MidiInput (midir, CoreMIDI/WinMM/ALSA), CC→ParamStore
+- [x] scheng-control-osc-wgpu: OscReceiver (non-blocking UDP poll), OSC→ParamStore
+- [x] scheng-hotreload: AssetWatcher (notify FSEvents/inotify), HotReloader (shader + params.json)
+- [x] CONTROL_LAYER_README.md: complete instrument wiring example
+
+### Phase 5 — Tauri Shell ✅ COMPLETE
+- [x] Create crates/scheng-tauri
+- [x] Embed scheng-runtime-wgpu in Tauri Rust backend on dedicated thread
+- [x] IPC surface: set_param, load_graph, set_output_mode, start/stop_recording, get_engine_status
+- [x] Preview frame IPC: readback → JPEG (scaled 320×180) → Tauri event ~15fps
+- [x] Instrument template: ui/index.html (param sliders, preview, output mode, recording)
+- [x] macOS: cargo tauri dev confirmed running on Apple M1 Max
+
+
+### First-run: create assets/
+
+The render thread looks for `assets/` relative to CWD.
+Create these two files to get live preview working:
+
+```bash
+mkdir -p assets/shaders
+
+# assets/params.json
+cat > assets/params.json << 'JSON'
+{"version":1,"params":[{"name":"u_speed","min":0,"max":5,"default":1,"smooth":0.05,"midi_cc":1}]}
+JSON
+
+# assets/shaders/default.frag
+cat > assets/shaders/default.frag << 'GLSL'
+#version 330 core
+in vec2 v_uv;
+out vec4 fragColor;
+uniform float uTime;
+void main() {
+    float r = v_uv.x + 0.5 * sin(uTime);
+    float g = v_uv.y + 0.5 * cos(uTime * 0.7);
+    fragColor = vec4(r, g, 0.2, 1.0);
+}
+GLSL
+```
+
+The render thread hot-reloads both files — edit and save while running.
+
+### Phase 6 — Shader Library (LZX-inspired)
+- [ ] Colorizer (hue rotation, RGB↔component)
+- [ ] Ramp generator (H, V, radial, angular)
+- [ ] Luma keyer / chroma keyer
+- [ ] Hard keyer / soft keyer
+- [ ] Proc amp (brightness, contrast, saturation, hue)
+- [ ] Crossfader with T-bar uniform
+- [ ] Matrix mixer 4→1
+- [ ] Video feedback (ping-pong convergence)
+- [ ] Pattern generator (color bars, test card, grid)
+- [ ] Waveform monitor / vectorscope
+
+### Phase 7 — GUI / Editor (design before building)
+- [ ] Node graph editor research
+- [ ] Prototyping → export workflow definition
+- [ ] JSON graph save/load format
+- [ ] Parameter UI contract
+
+---

+# scheng — Development Reference
+> Last updated: 2026-03-15 — Phase 1 complete
+
+---
+
+## Project North Star
+
+scheng is a Rust SDK for building GPU-accelerated video synthesis instruments.
+Node-graph execution model, explicit shader contracts, modular I/O (Syphon, Spout,
+NDI, FFmpeg). Instruments ship cross-platform via Tauri. Shader layer is intentionally
+low-level — enabling faithful reproductions of historical analog video synthesis hardware.
+
+shadecore = proven single-binary reference. Features that work there are the target spec.
+
+---
+
+## Phase 1 — wgpu Backend ✅ COMPLETE

+### Key lessons learned (bugs fixed)
+
+| Bug | Root cause | Fix |
+|-----|-----------|-----|
+| `naga validate` feature missing | Feature doesn't exist in naga 22 | Removed from Cargo.toml |
+| `scheng_core::FrameCtx` not found | FrameCtx lives in scheng-runtime-glow | Define locally in frame_ctx.rs |
+| `plan.node_ids()` not found | Plan has `pub nodes: Vec<NodeId>` field | Use `plan.nodes.iter()` |
+| `NodeKind` not Copy | Clone needed | Take `&NodeKind` throughout |
+| Borrow conflict (mut+immut on render_targets) | entry().or_insert_with() held mut borrow | Split into Phase A (resize) + Phase B (encode) |
+| Borrow conflict (pipeline + resolve_inputs) | get_or_create() held mut borrow on self | Free functions taking individual fields |
+| `errors.iter()` | naga ParseErrors has `.errors` field | `errors.errors.iter()` |
+| `@interpolate` mismatch | WGSL default is `perspective,center`; naga emits `perspective` | Add `@interpolate(perspective)` to vertex out |
+| All pixels zero | sink.present() called before queue.submit() | Collect outputs, submit first, then present |
+
+### GLSL shader contract (verified working)
+
+```glsl
+#version 330 core          // stripped by compat.rs, replaced with 450
+in vec2 v_uv;              // stripped, provided by compat header
+out vec4 fragColor;        // stripped, provided by compat header
+uniform sampler2D iChannel0; // stripped, replaced with split texture+sampler
+uniform float uTime;       // stripped, in FrameBlock
+uniform vec2 uResolution;  // stripped, in FrameBlock
+
+void main() {
+    fragColor = texture(iChannel0, v_uv) + vec4(uTime * 0.1, 0.0, 0.0, 0.0);
+}
+```
+
+### Bind group layout (fixed, matches compat header)
+
+| binding | resource | GLSL alias |
+|--------:|---------|------------|
+| 0 | texture2D | iChannel0_tex → iChannel0 macro |
+| 1 | texture2D | iChannel1_tex → iChannel1 macro |

+        };
+
+        runtime.execute_frame(&graph, &plan, &configs, &ctx, &mut sink)?;
+        frame += 1;
+    }
+}
+```
+
+---
+
+## OSC addressing
+
+Every param is addressable over OSC. Use the `osc_addr` field in params.json
+as the target address. The scheng editor shows the OSC address as a tooltip
+on every slider.
+
+```
+/scheng/node/proc/uniform/u_brightness  0.75
+/scheng/node/xfad/uniform/u_tbar        0.5
+```
+
+Short forms also work:
+```
+/param/u_brightness  0.75
+/u_tbar              0.5
+```
+
+Send from any OSC client (TouchOSC, Max/MSP, Python python-osc, etc.):
+```python
+from pythonosc.udp_client import SimpleUDPClient
+c = SimpleUDPClient("127.0.0.1", 9000)
+c.send_message("/scheng/node/proc/uniform/u_brightness", 0.75)
+```
+
+---
+
+## MIDI CC mapping
+
+Map CC numbers in params.json:
+
+```json
+{ "name": "u_tbar", "midi_cc": 7 }
+```
+
+List available MIDI ports:
+
+```bash
+# Quick port listing tool
+cargo run --example list_midi_ports -p scheng-input-midi
+```
+
+Or in code:
+```rust
+for port in MidiInput::list_ports().unwrap() {
+    println!("  {}", port);
+}
+```
+
+---
+
+## Hot-reload
+
+Edit a `.frag` file in `assets/shaders/` while the instrument is running.
+The watcher detects the change within ~100ms and the new shader compiles
+on the next frame. If the shader has a compile error, the old shader
+continues running — the error is logged but the instrument doesn't crash.
+
+Edit `assets/params.json` while running to add/remove/adjust params.
+Existing values are preserved; new params start at their defaults.
+
+---
+
+## Tests
+
+```bash
+# All control layer tests
+cargo test -p scheng-param-store -- --nocapture
+cargo test -p scheng-input-midi -- --nocapture
+cargo test -p scheng-control-osc-wgpu -- --nocapture

+
+## Project North Star
+
+**scheng** is a Rust SDK for building GPU-accelerated video synthesis instruments.
+It provides a node-graph execution model, explicit shader contracts, and a modular I/O surface.
+Instruments built on the SDK ship as cross-platform native applications via Tauri.
+The shader layer is intentionally low-level — enabling developers to implement any signal
+processing topology, including faithful reproductions of historical analog video synthesis hardware.
+
+**shadecore** = the proven single-binary reference implementation. Features that work there are the target spec for scheng's SDK crates.
+
+---
+
+## The wgpu Backend Decision
+
+### Decision: Dual Backend — Keep glow, Add wgpu
+
+**Don't delete `scheng-runtime-glow`. Add `scheng-runtime-wgpu` alongside it.**
+
+This is not a migration — it's an extension. The architecture already supports it because
+`scheng-runtime` is backend-agnostic. The `OutputSink` trait, `Plan`, `FrameCtx`, and
+`NodeProps` don't change at all.
+
+---
+
+### Why Keep glow
+
+- **shadecore validated it.** Syphon, Spout, NDI, FFmpeg, MIDI — everything works end-to-end in glow.
+- **GLSL shaders run as-is.** Your entire shader library is native GLSL. No translation needed.
+- **Linux/Windows still work fine with OpenGL 3.3+.** No deprecation concern there.
+- **It's the regression baseline.** Contract tests run against it. Keep it green.
+
+---
+
+### Why Add wgpu
+
+| Problem | glow | wgpu |
+|---|---|---|
+| macOS long-term | Deprecated (10.14+), translation layer | Metal native |
+| Tauri embedding | Separate GL window, hostile | First-class via `wgpu-core` |
+| Cross-platform one backend | No (GL quirks per platform) | Yes (Metal/DX12/Vulkan/WebGPU) |
+| WebGPU/browser future | No | Yes (same API) |
+| Shader language | GLSL only | WGSL + **GLSL via naga** |
+
+The GLSL → wgpu path works via **naga**, wgpu's shader translation library. Naga compiles
+GLSL fragment shaders to WGSL/SPIR-V/Metal at load time. This means your existing shader
+library stays GLSL — naga handles the translation transparently.
+
+```
+your .frag file (GLSL 330 core)
+       │
+       ▼ naga::front::glsl
+  naga IR (intermediate)
+       │
+       ├──▶ WGSL    (wgpu native / WebGPU)
+       ├──▶ MSL     (Metal / macOS / iOS)
+       ├──▶ HLSL    (DX12 / Windows)
+       └──▶ SPIR-V  (Vulkan / Linux)
+```
+
+**Known naga GLSL limitation:** naga's GLSL frontend targets GLSL 450 / Vulkan-style GLSL,
+not the exact `#version 330 core` profile used in shadecore. The delta is small:
+- `gl_FragCoord` works fine
+- `texture()` calls work fine
+- Extensions and legacy builtins may need minor adjustment
+- The `v_uv` vertex output convention is compatible
+
+Mitigation: write a small compatibility header injected at the top of every shader before
+naga compilation. This normalizes any 330→450 gaps transparently.
+
+---
+
+### How wgpu Slots Into the Crate Structure
+
+No existing crate changes. One new crate added:
+
+```
+crates/
+├── scheng-core              (unchanged)
+├── scheng-graph             (unchanged)
+├── scheng-runtime           (unchanged — abstract contracts)
+├── scheng-runtime-glow      (unchanged — proven baseline)
+├── scheng-runtime-wgpu      (NEW — Metal/DX12/Vulkan backend)
+│     ├── Depends on: scheng-runtime, scheng-graph, wgpu

+│     └── GLSL shaders compiled via naga at load time
+├── scheng-bridge            (unchanged)
+...
+```
+
+**Cargo feature flags on the host binary:**
+
+```toml
+[features]
+default  = ["backend-wgpu"]
+gl       = ["scheng-runtime-glow"]
+wgpu     = ["scheng-runtime-wgpu"]  # default going forward
+```
+
+---
+
+### Tauri Integration Model
+
+```
+Tauri Binary
+├── Rust backend
+│     ├── scheng-runtime-wgpu running on dedicated render thread
+│     ├── wgpu renders into offscreen texture (not visible yet)
+│     ├── OutputSink implementations: Syphon, Spout, NDI, FFmpeg
+│     └── Tauri commands: set_param, load_graph, set_output_mode
+│
+└── WebView (WKWebView on macOS, WebView2 on Windows)
+      ├── Instrument UI: parameter sliders, graph editor (future)
+      ├── Calls Tauri commands via invoke()
+      └── Receives preview frames via IPC (optional, downscaled JPEG/PNG)
+```
+
+The render loop runs entirely in native Rust. The WebView is a control surface only.
+Preview frames can be sent via Tauri's event system as base64-encoded images at 15-30fps —
+enough for monitoring without impacting GPU performance.

+- [ ] Design the preview display model in GUI context
+
+---
+
+## CLI Testing Guide
+
+### Prerequisites
+
+```bash
+# Install Rust stable
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+
+# macOS: Xcode CLI tools
+xcode-select --install
+
+# macOS + Syphon output: place Syphon.framework at vendor/Syphon.framework
+# Windows + Spout: C++ build tools required
+```
+
+### 1. Build everything
+
+```bash
+cd scheng
+cargo build --workspace
+```
+
+Expected: all crates compile, no errors.
+
+### 2. Run contract tests
+
+```bash
+cargo test -p scheng-contract-tests
+```
+
+Expected: all golden fixture tests pass. These pin the public SDK surface.
+If these fail after any change, the SDK has a regression.
+
+### 3. Run all tests
+
+```bash
+cargo test --workspace
+```
+
+### 4. Run the bridge (engine + browser editor)
+
+```bash
+cargo run -p scheng-bridge
+
+# With debug logging:
+RUST_LOG=scheng_bridge=debug cargo run -p scheng-bridge
+
+# Custom WebSocket address:
+SCHENG_BRIDGE_ADDR=0.0.0.0:7777 cargo run -p scheng-bridge
+```
+
+Then open `crates/scheng-bridge/scheng-editor.html` in Chrome/Firefox → Connect → load a template → Compile.
+
+### 5. Test OSC control
+
+```bash
+# Start bridge in one terminal
+cargo run -p scheng-bridge
+
+# Send OSC from another terminal (requires oscsend or similar)
+oscsend 127.0.0.1 9000 /scheng/node/xfad/uniform/u_tbar f 0.75
+oscsend 127.0.0.1 9000 /scheng/node/key/uniform/u_thresh f 0.35
+```
+
+### 6. Test contract tests with verbose output
+
+```bash
+cargo test -p scheng-contract-tests -- --nocapture
+```
+
+### 7. Validate sdk-compat (API regression check)
+
+```bash
+cargo build -p sdk-compat
+```
+
+This is a compile-only witness. If it doesn't compile, the public API has broken.
+
+### 8. Build with Syphon (macOS only)
+
+```bash
+cargo build -p scheng-runtime-glow --features syphon
+```
+
+### 9. Build with webcam input
+
+```bash
+cargo build -p scheng-input-webcam --features native
+```
+
+---
+
+## shadecore Reference Commands
+
+> shadecore is the proven single-binary reference. Use these to verify features work
+> before porting to scheng.
+
+```bash
+cd shadecore
+
+# Standard run
+cargo run
+
+# With NDI output
+cargo run --features ndi
+
+# Observe render hotkeys at runtime:
+# 1 = preview only
+# 2 = Syphon (macOS)
+# 3 = Spout (Windows)
+# 4 = FFmpeg stream
+# 6 = NDI
+```
+
+---
+
+## Key Architecture Rules (Never Violate)
+
+1. **The engine does not own time.** FrameCtx is always supplied by the host.
+2. **Topology is static after compile().** NodeProps is dynamic. Structural changes require recompile.
+3. **No layer reaches backward.** Graph → Runtime → Backend. Never reverse.
+4. **Control updates NodeProps only.** OSC/MIDI never touches the graph or render loop directly.
+5. **The runtime is single-threaded.** GL/wgpu context must be on the calling thread.
+6. **Errors are returned immediately.** No silent recovery anywhere in the engine.
+7. **Optional features are truly optional.** Syphon, Spout, webcam never bleed into core crates.
+
+---
+
+## GLSL Shader Contract (v_uv convention)
+
+All fragment shaders must follow this interface:
+
+```glsl
+#version 330 core
+in vec2 v_uv;               // lowercase — matches vertex shader out
+out vec4 fragColor;
+
+uniform sampler2D iChannel0; // input textures, up to iChannel3
+uniform float uTime;         // seconds since start
+uniform vec2 uResolution;    // output dimensions
+uniform int uFrame;          // monotonic frame counter
+
+// Custom params — u_ prefix by convention
+uniform float u_myParam;
+```
+
+Port mappings → texture units:
+| Port name | iChannel |
+|---|---|
+| `in`, `in0`, `a`, `src` | iChannel0 |
+| `in1`, `b`, `src1` | iChannel1 |
+| `in2`, `c`, `src2` | iChannel2 |
+| `in3`, `d`, `src3` | iChannel3 |

+## Open Questions (resolve before building)
+
+- [ ] **naga GLSL compatibility**: Run a shadecore shader through naga today. Document any
+       adjustments needed for the compat header.
+- [ ] **wgpu + winit on macOS**: Verify wgpu + winit event loop works without the OpenGL
+       path. The winit version in scheng-host-winit may need updating.
+- [ ] **Tauri + wgpu surface sharing**: Can wgpu render into a surface that Tauri's WebView
+       can composite over, or does the preview need to go through IPC frames?
+       Research: `wgpu` + `raw-window-handle` + Tauri's `setup` hook.
+- [ ] **shadecore Vosk resources**: Speech recognition library present in repo.
+       Intentional? If yes, add `scheng-input-voice` to Phase 2.
+- [ ] **Max/MSP integration**: `max/` directory in scheng repo. Define the IPC boundary.

+## Phase 1 Integration Notes
+
+### Files Created in This Session
+
+```
+crates/scheng-runtime-wgpu/
+├── Cargo.toml            ← dependencies: wgpu=22, naga=22, bytemuck, pollster, regex
+├── src/
+│   ├── lib.rs            ← public API, re-exports, WgpuError enum
+│   ├── context.rs        ← WgpuContext::new() — headless Device+Queue init
+│   ├── compat.rs         ← GLSL 330→450 preprocessor (strip, rewrite, inject header)

+└── tests/
+    └── headless.rs       ← 8 integration tests (compat, naga, GPU rendering, readback)
+```
+
+### Step 1: Add to Workspace
+
+In the root `Cargo.toml`, add to the `[workspace]` members list:
+```toml
+[workspace]
+members = [
+    "crates/scheng-core",
+    "crates/scheng-graph",
+    "crates/scheng-runtime",
+    "crates/scheng-runtime-glow",
+    "crates/scheng-runtime-wgpu",   # ← ADD THIS
+    # ... other crates
+]
+```
+
+### Step 2: Verify Plan API (CRITICAL — do this before running tests)
+
+The executor uses `plan.node_ids()`, `plan.node_kind(id)`, and `plan.inputs_for(id)`.
+These method names are assumed from the README. Check the actual scheng-graph source:
+
+```bash
+grep -n "pub fn" crates/scheng-graph/src/lib.rs
+```
+
+Adjust `executor.rs` to match. The three key calls:
+- Iterating plan nodes in order
+- Getting a node's `NodeKind`
+- Getting the upstream `(NodeId, channel_index)` pairs for a node's inputs
+
+### Step 3: Run the CPU-only tests first (no GPU needed)
+
+```bash
+cargo test -p scheng-runtime-wgpu test_compat_preprocessing -- --nocapture
+cargo test -p scheng-runtime-wgpu test_naga_glsl_compile -- --nocapture
+```
+
+These must pass before any GPU tests. If `test_naga_glsl_compile` fails:
+- The naga GLSL 450 source in compat.rs has a syntax error
+- Check the processed source printed by `--nocapture` for the exact error line
+
+### Step 4: Run GPU tests
+
+```bash
+cargo test -p scheng-runtime-wgpu -- --nocapture
+```
+
+If no adapter is found in CI: `WGPU_BACKEND=gl cargo test -p scheng-runtime-wgpu`
+
+### Step 5: Fix `once_cell` dependency
+
+`compat.rs` uses `once_cell::sync::Lazy` for compiled regexes.
+Add to Cargo.toml if not already present in workspace:
+```toml
+once_cell = "1"
+```
+Or replace with `std::sync::OnceLock` (Rust 1.70+):
+```rust
+use std::sync::OnceLock;
+static RE_VERSION: OnceLock<Regex> = OnceLock::new();
+// in the function:
+RE_VERSION.get_or_init(|| Regex::new(...).unwrap())
+```
+
+### Known Phase 1 Gaps (to fix in 1.2/1.3)
+
+| Gap | Location | Phase |
+|---|---|---|
+| Custom u_ uniforms stripped with warning | compat.rs, executor.rs | 1.2 |
+| plan.inputs_for() API needs verification | executor.rs line ~140 | NOW |
+| plan.node_kind() API needs verification | executor.rs line ~105 | NOW |
+| Y-axis flip vs OpenGL convention | render_target.rs, shader.rs | 1.5 |
+| Vertex module created per-pipeline (wasteful) | pipeline.rs | 1.2 |
+| PingPong / Feedback node support | executor.rs | 1.3 |
+| Hot-reload: recompile on source change | executor.rs | Phase 4 |
+| scheng-runtime NodeProps integration | executor.rs NodeConfig | After API verified |

+# scheng Shader Library — Phase 6
+
+LZX-inspired analog video synthesis modules implemented as GLSL 330 shaders.
+
+Each shader is a self-contained `.frag` file that works with the scheng compat
+header. All use the `iChannel0–3` / `uTime` / `uResolution` convention.
+
+---
+
+## Module Reference
+
+### proc-amp.frag — Processing Amplifier
+**Type:** Processor (1 input)
+
+Broadcast-standard video processing in YIQ colour space (NTSC).
+Adjusts brightness (luma offset), contrast (luma gain around mid-grey),
+saturation (chroma amplitude), and hue (IQ vector rotation).
+
+Hardware reference: Extron DA2 proc amp, Kramer VP-41 series.
+
+```
+iChannel0 → [brightness → contrast → saturation → hue rotation] → out
+```
+
+| Uniform | Range | Default | Notes |
+|---------|-------|---------|-------|
+| u_brightness | -1 to 1 | 0.0 | IRE shift |

+
+---
+
+### colorizer.frag — Colour Encoder
+**Type:** Processor (1 input)
+
+Maps input luminance to a configurable hue sweep. A luma=0 pixel becomes
+`u_hue_start`; luma=1 becomes `u_hue_start + u_hue_range`.
+Creates false colour effects, colour encoding of greyscale signals,
+and thermal-style visualisations.
+
+Hardware reference: LZX Visual Cortex colouriser, Fairlight CVI colour encoder.

+over iChannel2 (bg). Soft key uses smoothstep for feathered edges.
+
+Hardware reference: LZX Cadet IV key generator, Panasonic MX-50 keyer.
+
+```
+iChannel0 (key source) → [threshold + softness] → matte
+matte → mix(iChannel2, iChannel1, matte) → out
+```
+
+| Uniform | Range | Default | Notes |
+|---------|-------|---------|-------|

+
+| Uniform | Range | Default | Notes |
+|---------|-------|---------|-------|
+| u_key_hue | 0–360 | 120.0 | 120=green, 240=blue |
+| u_hue_range | 0–180 | 30.0 | Acceptance range ± |
+| u_saturation | 0–1 | 0.2 | Min sat to key |

+Hardware reference: LZX Cadet VIII, broadcast vision mixer T-bar.
+
+| Uniform | Range | Default | Notes |
+|---------|-------|---------|-------|
+| u_tbar | 0–1 | 0.5 | 0=full A, 1=full B |
+| u_mode | 0–4 | 0 | dissolve/add/mult/hard-wipe/soft-wipe |

+
+---
+
+### matrix-mixer.frag — Matrix Mixer 4→1
+**Type:** Mixer (4 inputs)
+
+Weighted sum of up to 4 channels. Negative gains invert (phase reversal).
+DC offset adds a constant bias. The core routing primitive of analog synthesis.
+
+Hardware reference: LZX Matrix Mixer, Buchla 256 spatial sound director.
+
+| Uniform | Range | Default | Notes |
+|---------|-------|---------|-------|

+Mix live source with a transformed version of the previous frame.
+Zoom + rotation + drift create the characteristic feedback spiral.
+**Connect iChannel1 to a PreviousFrame node** in the graph.
+
+Hardware reference: LZX Cadet VI lag processor, physical camera-monitor loops.
+
+| Uniform | Range | Default | Notes |

+# scheng — Development Reference
+> Living document. Update as work progresses.
+> Last updated: 2026-03-15
+
+---
+
+## Project North Star
+
+**scheng** is a Rust SDK for building GPU-accelerated video synthesis instruments.
+It provides a node-graph execution model, explicit shader contracts, and a modular I/O surface.
+Instruments built on the SDK ship as cross-platform native applications via Tauri.
+The shader layer is intentionally low-level — enabling developers to implement any signal
+processing topology, including faithful reproductions of historical analog video synthesis hardware.
+
+**shadecore** = the proven single-binary reference implementation. Features that work there are the target spec for scheng's SDK crates.
+
+---
+
+## The wgpu Backend Decision
+
+### Decision: Dual Backend — Keep glow, Add wgpu
+
+**Don't delete `scheng-runtime-glow`. Add `scheng-runtime-wgpu` alongside it.**
+
+This is not a migration — it's an extension. The architecture already supports it because
+`scheng-runtime` is backend-agnostic. The `OutputSink` trait, `Plan`, `FrameCtx`, and
+`NodeProps` don't change at all.
+
+---
+
+### Why Keep glow
+
+- **shadecore validated it.** Syphon, Spout, NDI, FFmpeg, MIDI — everything works end-to-end in glow.
+- **GLSL shaders run as-is.** Your entire shader library is native GLSL. No translation needed.
+- **Linux/Windows still work fine with OpenGL 3.3+.** No deprecation concern there.
+- **It's the regression baseline.** Contract tests run against it. Keep it green.
+
+---
+
+### Why Add wgpu
+
+| Problem | glow | wgpu |
+|---|---|---|
+| macOS long-term | Deprecated (10.14+), translation layer | Metal native |
+| Tauri embedding | Separate GL window, hostile | First-class via `wgpu-core` |
+| Cross-platform one backend | No (GL quirks per platform) | Yes (Metal/DX12/Vulkan/WebGPU) |
+| WebGPU/browser future | No | Yes (same API) |
+| Shader language | GLSL only | WGSL + **GLSL via naga** |
+
+The GLSL → wgpu path works via **naga**, wgpu's shader translation library. Naga compiles
+GLSL fragment shaders to WGSL/SPIR-V/Metal at load time. This means your existing shader
+library stays GLSL — naga handles the translation transparently.
+
+```
+your .frag file (GLSL 330 core)
+       │
+       ▼ naga::front::glsl
+  naga IR (intermediate)
+       │
+       ├──▶ WGSL    (wgpu native / WebGPU)
+       ├──▶ MSL     (Metal / macOS / iOS)
+       ├──▶ HLSL    (DX12 / Windows)
+       └──▶ SPIR-V  (Vulkan / Linux)
+```
+
+**Known naga GLSL limitation:** naga's GLSL frontend targets GLSL 450 / Vulkan-style GLSL,
+not the exact `#version 330 core` profile used in shadecore. The delta is small:
+- `gl_FragCoord` works fine
+- `texture()` calls work fine
+- Extensions and legacy builtins may need minor adjustment
+- The `v_uv` vertex output convention is compatible
+
+Mitigation: write a small compatibility header injected at the top of every shader before
+naga compilation. This normalizes any 330→450 gaps transparently.
+
+---
+
+### How wgpu Slots Into the Crate Structure
+
+No existing crate changes. One new crate added:

+
+### Tauri Integration Model
+
+```
+Tauri Binary
+├── Rust backend
+│     ├── scheng-runtime-wgpu running on dedicated render thread
+│     ├── wgpu renders into offscreen texture (not visible yet)
+│     ├── OutputSink implementations: Syphon, Spout, NDI, FFmpeg
+│     └── Tauri commands: set_param, load_graph, set_output_mode
+│
+└── WebView (WKWebView on macOS, WebView2 on Windows)
+      ├── Instrument UI: parameter sliders, graph editor (future)
+      ├── Calls Tauri commands via invoke()
+      └── Receives preview frames via IPC (optional, downscaled JPEG/PNG)
+```
+
+The render loop runs entirely in native Rust. The WebView is a control surface only.
+Preview frames can be sent via Tauri's event system as base64-encoded images at 15-30fps —
+enough for monitoring without impacting GPU performance.

+- [ ] Port MIDI from shadecore into `scheng-input-midi`
+- [ ] `scrubbable_controls`: verify keymap.json / osc_map.json hot-reload
+- [ ] State ownership model: match shadecore's authority table
+  - render.json → active shader
+  - params.json → parameter defaults + MIDI map
+  - output.json → output mode + hotkeys
+  - recording.json → recording profiles
+- [ ] Hot-reload: file watcher → reload shader source without restart (port hotreload.rs)
+
+---
+
+### Phase 5 — Tauri Shell
+
+- [ ] Create `crates/scheng-tauri` — the Tauri integration crate
+- [ ] Embed scheng-runtime-wgpu in Tauri backend
+- [ ] Define IPC command surface:
+  - `set_param(node_id, param_name, value: f32)`

+- [ ] Create minimal instrument template (fork-ready)
+- [ ] Test: macOS `.app` build via `tauri build`
+- [ ] Test: Windows `.exe` build via `tauri build`
+- [ ] Test: Linux build via `tauri build`
+
+---
+
+### Phase 6 — Shader Library (LZX-inspired)
+
+> Goal: reverse-engineer historical analog video synthesis hardware as GLSL shaders.
+> Each shader = a documented module with its own params.json profile.
+
+- [ ] Colorizer (hue rotation, RGB→component, component→RGB)
+- [ ] Ramp generator (horizontal, vertical, radial, angular)
+- [ ] Key generator (luma key, chroma key, threshold)
+- [ ] Hard keyer
+- [ ] Soft keyer
+- [ ] Fade to black / white
+- [ ] Proc amp (brightness, contrast, saturation, hue)
+- [ ] Sync processor (H-sync, V-sync simulation)
+- [ ] Video feedback (ping-pong, convergence modes)
+- [ ] Matrix mixer 4→1 (weighted sum)
+- [ ] Crossfader (T-bar, soft cuts)
+- [ ] Waveform monitor (parade, overlay)
+- [ ] Vectorscope
+- [ ] Pattern generator (color bars, test card, grid)
+
+---
+
+### Phase 7 — GUI / Editor (deferred — design carefully)
+
+> Don't build until the SDK surface is stable and fully tested CLI-first.
+
+- [ ] Research: node graph editor options (egui, iced, or Tauri-based)
+- [ ] Define the prototyping → export workflow
+- [ ] Define the JSON graph format for save/load
+- [ ] Design the parameter UI contract (sliders, toggles, XY pads)
+- [ ] Design the preview display model in GUI context
+
+---
+
+## CLI Testing Guide
+
+### Prerequisites
+
+```bash
+# Install Rust stable
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+
+# macOS: Xcode CLI tools
+xcode-select --install
+
+# macOS + Syphon output: place Syphon.framework at vendor/Syphon.framework
+# Windows + Spout: C++ build tools required
+```
+
+### 1. Build everything
+
+```bash
+cd scheng
+cargo build --workspace
+```
+
+Expected: all crates compile, no errors.
+
+### 2. Run contract tests
+
+```bash
+cargo test -p scheng-contract-tests
+```
+
+Expected: all golden fixture tests pass. These pin the public SDK surface.
+If these fail after any change, the SDK has a regression.
+
+### 3. Run all tests
+
+```bash
+cargo test --workspace
+```
+
+### 4. Run the bridge (engine + browser editor)
+
+```bash
+cargo run -p scheng-bridge
+
+# With debug logging:
+RUST_LOG=scheng_bridge=debug cargo run -p scheng-bridge
+
+# Custom WebSocket address:
+SCHENG_BRIDGE_ADDR=0.0.0.0:7777 cargo run -p scheng-bridge
+```
+
+Then open `crates/scheng-bridge/scheng-editor.html` in Chrome/Firefox → Connect → load a template → Compile.
+
+### 5. Test OSC control
+
+```bash
+# Start bridge in one terminal
+cargo run -p scheng-bridge
+
+# Send OSC from another terminal (requires oscsend or similar)
+oscsend 127.0.0.1 9000 /scheng/node/xfad/uniform/u_tbar f 0.75
+oscsend 127.0.0.1 9000 /scheng/node/key/uniform/u_thresh f 0.35
+```
+
+### 6. Test contract tests with verbose output
+
+```bash
+cargo test -p scheng-contract-tests -- --nocapture
+```
+
+### 7. Validate sdk-compat (API regression check)
+
+```bash
+cargo build -p sdk-compat
+```
+
+This is a compile-only witness. If it doesn't compile, the public API has broken.
+
+### 8. Build with Syphon (macOS only)
+
+```bash
+cargo build -p scheng-runtime-glow --features syphon
+```
+
+### 9. Build with webcam input
+
+```bash
+cargo build -p scheng-input-webcam --features native
+```
+
+---
+
+## shadecore Reference Commands
+
+> shadecore is the proven single-binary reference. Use these to verify features work
+> before porting to scheng.
+
+```bash
+cd shadecore
+
+# Standard run
+cargo run
+
+# With NDI output
+cargo run --features ndi
+
+# Observe render hotkeys at runtime:
+# 1 = preview only
+# 2 = Syphon (macOS)
+# 3 = Spout (Windows)
+# 4 = FFmpeg stream
+# 6 = NDI
+```
+
+---
+
+## Key Architecture Rules (Never Violate)
+
+1. **The engine does not own time.** FrameCtx is always supplied by the host.
+2. **Topology is static after compile().** NodeProps is dynamic. Structural changes require recompile.
+3. **No layer reaches backward.** Graph → Runtime → Backend. Never reverse.
+4. **Control updates NodeProps only.** OSC/MIDI never touches the graph or render loop directly.
+5. **The runtime is single-threaded.** GL/wgpu context must be on the calling thread.
+6. **Errors are returned immediately.** No silent recovery anywhere in the engine.
+7. **Optional features are truly optional.** Syphon, Spout, webcam never bleed into core crates.
+
+---
+
+## GLSL Shader Contract (v_uv convention)
+
+All fragment shaders must follow this interface:
+
+```glsl
+#version 330 core
+in vec2 v_uv;               // lowercase — matches vertex shader out
+out vec4 fragColor;
+
+uniform sampler2D iChannel0; // input textures, up to iChannel3
+uniform float uTime;         // seconds since start
+uniform vec2 uResolution;    // output dimensions
+uniform int uFrame;          // monotonic frame counter
+
+// Custom params — u_ prefix by convention
+uniform float u_myParam;
+```
+
+Port mappings → texture units:
+| Port name | iChannel |
+|---|---|
+| `in`, `in0`, `a`, `src` | iChannel0 |
+| `in1`, `b`, `src1` | iChannel1 |
+| `in2`, `c`, `src2` | iChannel2 |
+| `in3`, `d`, `src3` | iChannel3 |

+## Open Questions (resolve before building)
+
+- [ ] **naga GLSL compatibility**: Run a shadecore shader through naga today. Document any
+       adjustments needed for the compat header.
+- [ ] **wgpu + winit on macOS**: Verify wgpu + winit event loop works without the OpenGL
+       path. The winit version in scheng-host-winit may need updating.
+- [ ] **Tauri + wgpu surface sharing**: Can wgpu render into a surface that Tauri's WebView
+       can composite over, or does the preview need to go through IPC frames?
+       Research: `wgpu` + `raw-window-handle` + Tauri's `setup` hook.
+- [ ] **shadecore Vosk resources**: Speech recognition library present in repo.
+       Intentional? If yes, add `scheng-input-voice` to Phase 2.
+- [ ] **Max/MSP integration**: `max/` directory in scheng repo. Define the IPC boundary.

+```
+
+### Step 1: Add to Workspace
+
+In the root `Cargo.toml`, add to the `[workspace]` members list:
+```toml
+[workspace]
+members = [
+    "crates/scheng-core",
+    "crates/scheng-graph",
+    "crates/scheng-runtime",
+    "crates/scheng-runtime-glow",
+    "crates/scheng-runtime-wgpu",   # ← ADD THIS
+    # ... other crates
+]
+```
+
+### Step 2: Verify Plan API (CRITICAL — do this before running tests)
+
+The executor uses `plan.node_ids()`, `plan.node_kind(id)`, and `plan.inputs_for(id)`.
+These method names are assumed from the README. Check the actual scheng-graph source:
+
+```bash
+grep -n "pub fn" crates/scheng-graph/src/lib.rs
+```
+
+Adjust `executor.rs` to match. The three key calls:
+- Iterating plan nodes in order
+- Getting a node's `NodeKind`
+- Getting the upstream `(NodeId, channel_index)` pairs for a node's inputs
+
+### Step 3: Run the CPU-only tests first (no GPU needed)
+
+```bash
+cargo test -p scheng-runtime-wgpu test_compat_preprocessing -- --nocapture
+cargo test -p scheng-runtime-wgpu test_naga_glsl_compile -- --nocapture
+```
+
+These must pass before any GPU tests. If `test_naga_glsl_compile` fails:
+- The naga GLSL 450 source in compat.rs has a syntax error
+- Check the processed source printed by `--nocapture` for the exact error line
+
+### Step 4: Run GPU tests
+
+```bash
+cargo test -p scheng-runtime-wgpu -- --nocapture
+```
+
+If no adapter is found in CI: `WGPU_BACKEND=gl cargo test -p scheng-runtime-wgpu`
+
+### Step 5: Fix `once_cell` dependency
+
+`compat.rs` uses `once_cell::sync::Lazy` for compiled regexes.
+Add to Cargo.toml if not already present in workspace:
+```toml
+once_cell = "1"
+```
+Or replace with `std::sync::OnceLock` (Rust 1.70+):
+```rust
+use std::sync::OnceLock;
+static RE_VERSION: OnceLock<Regex> = OnceLock::new();
+// in the function:
+RE_VERSION.get_or_init(|| Regex::new(...).unwrap())
+```
+
+### Known Phase 1 Gaps (to fix in 1.2/1.3)
+
+| Gap | Location | Phase |
+|---|---|---|
+| Custom u_ uniforms stripped with warning | compat.rs, executor.rs | 1.2 |
+| plan.inputs_for() API needs verification | executor.rs line ~140 | NOW |
+| plan.node_kind() API needs verification | executor.rs line ~105 | NOW |
+| Y-axis flip vs OpenGL convention | render_target.rs, shader.rs | 1.5 |
+| Vertex module created per-pipeline (wasteful) | pipeline.rs | 1.2 |
+| PingPong / Feedback node support | executor.rs | 1.3 |
+| Hot-reload: recompile on source change | executor.rs | Phase 4 |
+| scheng-runtime NodeProps integration | executor.rs NodeConfig | After API verified |

+//! `scheng-input-midi`
+//!
+//! MIDI CC input for scheng. Runs on a background thread; writes to
+//! `ParamStore` via `Arc<Mutex<ParamStore>>`.
+//!
+//! # Design (matches shadecore's model)
+//!
+//! MIDI runs on its own thread — the `midir` callback fires from a platform
+//! MIDI thread (CoreMIDI on macOS, WinMM on Windows, ALSA on Linux).
+//! The callback acquires a `Mutex<ParamStore>` lock and calls
+//! `store.set_by_midi_cc(cc, value)`. Lock contention is negligible
+//! (<1µs for a single f32 write at 44100 events/sec worst case).
+//!
+//! The render loop reads smoothed values from `store.step_frame()` each frame.
+//! MIDI messages between frames collapse to "latest value wins" — no queue.
+//!
+//! # Supported messages
+//!
+//! - **Control Change (CC)** — primary; maps CC number to param via schema
+//! - Note On/Off, Program Change, Pitch Bend — logged but ignored by default
+//!   (extend `handle_message` for your instrument)
+//!
+//! # Quick start
+//!
+//! ```rust,ignore
+//! use std::sync::{Arc, Mutex};
+//! use scheng_param_store::ParamStore;
+//! use scheng_input_midi::MidiInput;
+//!
+//! let store = Arc::new(Mutex::new(
+//!     ParamStore::from_json_file("assets/params.json").unwrap()
+//! ));
+//!
+//! // Connect to first available MIDI port (or specify by name)
+//! let midi = MidiInput::connect_first(Arc::clone(&store)).unwrap();
+//!
+//! // The connection runs in the background. Keep `midi` alive for the
+//! // instrument's lifetime — dropping it disconnects MIDI.
+//!
+//! // Render loop:
+//! // store.lock().unwrap().step_frame();
+//! // let configs = builder.build(&store.lock().unwrap());

+//! Pull a live RTMP or RTSP stream via an ffmpeg subprocess and upload
+//! decoded frames to a wgpu RGBA texture each render cycle.
+//!
+//! Works with any URL ffmpeg can read:
+//! - `rtmp://server/live/key`
+//! - `rtmps://server/live/key`
+//! - `rtsp://camera/stream`
+//! - `srt://server:1234`

+//! # Architecture
+//!
+//! ```text
+//! ffmpeg subprocess
+//!   -i <url> -f rawvideo -pix_fmt rgba pipe:1
+//!     → stdout → bounded channel
+//!
+//! render thread
+//!   RtmpReceiver::poll(&device, &queue)
+//!     → drain channel → upload latest frame to wgpu texture
+//! ```
+//!
+//! # Usage
+//!
+//! ```rust,ignore
+//! use scheng_input_rtmp::RtmpReceiver;
+//!
+//! let mut recv = RtmpReceiver::open("rtmp://localhost/live/key", 1280, 720, &device, &queue)?;

+//! `scheng-input-video`
+//!
+//! Video file decoder → wgpu RGBA texture for scheng `VideoDecodeSource` nodes.
+//!
+//! # Design
+//!
+//! `VideoDecoder` opens a video file, decodes frames on demand, and uploads
+//! them to a wgpu texture. The texture is then passed to the graph as the
+//! `VideoDecodeSource` node's output — downstream nodes sample it via iChannel0.
+//!
+//! Frame selection is time-based: `FrameCtx::time` (seconds) maps to a frame
+//! index using the clip's nominal fps. This matches shadecore's model exactly.
+//!
+//! # Usage
+//!
+//! ```rust,ignore
+//! use scheng_input_video::VideoDecoder;
+//!
+//! // Open a video file
+//! let mut decoder = VideoDecoder::open("assets/clip.mp4", &device, &queue)?;
+//!
+//! // Each frame: upload the frame at the current time position
+//! decoder.upload_frame(ctx.time, &queue);
+//!
+//! // The texture is available for binding
+//! let texture_view = decoder.texture_view();
+//! ```
+//!
+//! # Feature flags
+//!
+//! - `decode` (default): enables ffmpeg-next decoding
+//! - Without `decode`: `VideoDecoder::open` returns `VideoError::NotEnabled`

+//! `node.rs` — VideoDecodeSource integration with the scheng graph executor.
+//!
+//! `VideoSourceManager` sits alongside `WgpuRuntime` in the instrument.
+//! Before calling `execute_frame()`, call `manager.update()` to decode the
+//! current frame and inject it into `NodeConfig::frag_shader` via iChannel0.
+//!
+//! # How it works
+//!
+//! A `VideoDecodeSource` node is just a `ShaderSource` that samples iChannel0.
+//! The instrument registers which file goes with which node. Each frame:
+//!
+//! 1. `VideoSourceManager::update()` calls `decoder.upload_frame(time, queue)`
+//!    for each registered node — uploads the decoded RGBA pixels to a wgpu texture.
+//!
+//! 2. The texture is NOT injected via iChannel0 binding automatically — the
+//!    executor's iChannel0 binding always comes from the graph's upstream node.
+//!    Instead, `VideoDecodeSource` shaders use a dedicated iChannel0 that the
+//!    manager writes to by overriding the blank texture in the bind group.
+//!
+//! # Integration path (Phase 2.1 — full bind group override)
+//!
+//! Full integration requires the executor to accept external texture overrides
+//! per node — a `TextureOverride` map alongside `NodeConfig`. This is the
+//! cleanest API. For now, the video texture is exposed via `texture_view()` and
+//! the instrument can inject it as the upstream node's output.
+//!
+//! # Simple integration pattern (works today)
+//!
+//! ```rust,ignore
+//! // Register video files at startup
+//! let mut video_mgr = VideoSourceManager::new();
+//! video_mgr.register(src_node, "assets/clip.mp4", &device, &queue)?;
+//!
+//! // Each frame — before execute_frame:
+//! video_mgr.update(ctx.time, &queue);
+//!
+//! // execute_frame runs normally — the video texture is the source
+//! runtime.execute_frame(&graph, &plan, &configs, &ctx, &mut sink)?;

+//!   execute_frame() → FfmpegSink::present()
+//!     → readback pixels (Vec<u8> RGBA)

+//!     write frame bytes → ffmpeg stdin pipe

+# scheng-tauri — Setup & Build Guide
+
+## Prerequisites
+
+### All platforms
+```bash
+# Rust stable
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+
+# Tauri CLI v2
+cargo install tauri-cli --version "^2"
+```
+
+### macOS
+```bash
+xcode-select --install
+```
+
+### Windows
+- Visual Studio Build Tools (C++ workload)
+- WebView2 (bundled with Windows 11, install separately on Windows 10)
+
+### Linux
+```bash
+sudo apt install libwebkit2gtk-4.1-dev libgtk-3-dev libayatana-appindicator3-dev librsvg2-dev
+```
+
+---
+
+## Add to workspace
+
+In root `Cargo.toml`:
+
+```toml
+[workspace]
+members = [
+    # ... existing crates ...
+    "crates/scheng-tauri",
+]
+```
+
+---
+
+## Directory layout
+
+```
+crates/scheng-tauri/
+├── Cargo.toml
+├── build.rs
+├── tauri.conf.json
+├── src/
+│   ├── main.rs         # binary entry point (just calls run())
+│   ├── lib.rs          # Tauri builder + setup

+└── ui/
+    └── index.html      # instrument UI (pure HTML/CSS/JS, no bundler needed)
+```
+
+---
+
+## Icons
+
+Tauri requires app icons. Generate them from a 1024×1024 PNG:
+
+```bash
+# Using the Tauri icon generator
+cargo tauri icon path/to/your/icon.png
+# Places icons in src-tauri/icons/ — move to crates/scheng-tauri/icons/
+```
+
+Or create a placeholder for development:
+```bash
+mkdir -p crates/scheng-tauri/icons
+# Copy icons from an existing Tauri template, or create minimal placeholders
+```
+
+---
+
+## Development run
+
+```bash
+# From the workspace root:
+cargo tauri dev --manifest-path crates/scheng-tauri/Cargo.toml
+
+# Or cd into the crate:
+cd crates/scheng-tauri
+cargo tauri dev
+```
+
+This opens a native window with the WebView UI and the scheng render running live.
+
+---
+
+## Production build
+
+```bash
+# macOS .app
+cargo tauri build --manifest-path crates/scheng-tauri/Cargo.toml
+
+# macOS universal (Intel + Apple Silicon)
+cargo tauri build --target universal-apple-darwin
+
+# Windows .exe + NSIS installer
+# (run on Windows or cross-compile)
+cargo tauri build
+
+# Linux .deb + AppImage
+cargo tauri build
+```
+
+Output: `target/release/bundle/`
+
+---
+
+## Syphon output (macOS)
+
+Enable the syphon feature and place `Syphon.framework` in `vendor/`:
+
+```toml
+# In your instrument's Cargo.toml or via feature flag:
+scheng-tauri = { path = "crates/scheng-tauri", features = ["syphon"] }
+```
+
+```bash
+cargo tauri build --features syphon
+```
+
+---
+
+## Assets directory
+
+The render loop looks for `assets/` relative to the working directory.
+For development, run from the workspace root or set the working directory:
+
+```
+assets/
+├── params.json            ← parameter schema (hot-reloaded)
+├── shaders/
+│   └── default.frag       ← main fragment shader (hot-reloaded)
+└── output.json            ← optional output config
+```
+
+Minimal `assets/params.json`:
+```json
+{
+  "version": 1,
+  "params": [
+    {
+      "name": "u_speed",
+      "min": 0.0,
+      "max": 5.0,
+      "default": 1.0,
+      "smooth": 0.05,
+      "midi_cc": 1
+    }
+  ]
+}
+```
+
+Minimal `assets/shaders/default.frag`:
+```glsl
+#version 330 core
+in vec2 v_uv;
+out vec4 fragColor;
+uniform float uTime;
+uniform vec2 uResolution;
+
+void main() {
+    float r = v_uv.x + 0.5 * sin(uTime);
+    float g = v_uv.y + 0.5 * cos(uTime * 0.7);
+    fragColor = vec4(r, g, 0.2, 1.0);

+//! `builder.rs` — NodeConfigBuilder: maps ParamStore values into NodeConfigs.
+//!
+//! The render loop calls `build()` each frame to get the `HashMap<NodeId, NodeConfig>`
+//! that `WgpuRuntime::execute_frame` expects.
+//!
+//! # Routing model
+//!
+//! Each param definition has an optional `node_label` field.
+//! The builder matches node labels to NodeIds via a label→NodeId map
+//! that the instrument registers once at startup.
+//!
+//! Params without a `node_label` are broadcast to all nodes — this lets
+//! global params like `u_time_scale` or `u_master_gain` apply everywhere
+//! without per-node routing.
+//!
+//! # Custom frag shaders
+//!
+//! The builder does NOT set `frag_shader` — shaders are managed by
+//! `scheng-hotreload` (or set once at startup). The builder only injects
+//! the current param values so the upcoming custom uniform support in
+//! Phase 1.2 can pick them up.

+# scheng — Development Reference

+
+---
+
+## Project North Star
+
+scheng is a Rust SDK for building GPU-accelerated video synthesis instruments.
+Node-graph execution model, explicit shader contracts, modular I/O (Syphon, Spout,
+NDI, FFmpeg). Instruments ship cross-platform via Tauri. Shader layer is intentionally
+low-level — enabling faithful reproductions of historical analog video synthesis hardware.
+
+shadecore = proven single-binary reference. Features that work there are the target spec.

+## Master Punchlist
+
+Status: `[x]` done · `[~]` in progress · `[ ]` todo · `[!]` blocked
+
+### Phase 0 — Baseline

+- [x] Map shadecore features → scheng SDK gaps
+- [x] wgpu backend decision
+- [ ] Verify `cargo build --workspace` passes clean on current main
+- [ ] Verify `cargo test -p scheng-contract-tests` passes
+
+### Phase 1 — wgpu Backend ✅ COMPLETE (11/11 tests on Apple M1 Max)
+- [x] scheng-runtime-wgpu: WgpuContext (Metal/DX12/Vulkan headless init)
+- [x] compat.rs: GLSL 330→450 preprocessor (bindings 0-5, split iChannelN, #define aliases)

+  - compat.rs: u_name → u_custom[N] replacement, CustomBlock at binding 6
+  - uniforms.rs: CustomUniformBuffer per node
+  - pipeline.rs: binding 6 in BGL
+  - executor.rs: writes CustomBlock per draw call
+  - 2 new tests: test_custom_uniforms_reach_shader, test_custom_uniform_zero_default
+- [ ] PingPong buffers for Feedback/PreviousFrame — Phase 1.3
+
+### Phase 2 — Input Layer
+- [ ] scheng-input-video: wgpu texture upload path
+- [ ] scheng-input-webcam: wgpu upload path
+- [ ] scheng-input-ndi (receive side)
+- [ ] scheng-input-syphon (macOS receive)
+- [ ] scheng-input-spout (Windows receive)
+
+### Phase 3 — Output Layer ✅ COMPLETE
+- [x] scheng-output-ffmpeg: FfmpegSink, FfmpegWorker, FfmpegConfig (RTSP/RTMP/File)

+- [~] scheng-output-ndi: NdiSink + NdiConfig ready — wire NDI SDK Rust bindings
+- [x] Headless OutputSink: PixelReadbackSink in scheng-runtime-wgpu
+
+### Phase 4 — Control Layer ✅ COMPLETE
+- [x] scheng-param-store: ParamSchema (params.json), ParamStore (targets+smoothing), NodeConfigBuilder
+- [x] scheng-input-midi: MidiInput (midir, CoreMIDI/WinMM/ALSA), CC→ParamStore
+- [x] scheng-control-osc-wgpu: OscReceiver (non-blocking UDP poll), OSC→ParamStore
+- [x] scheng-hotreload: AssetWatcher (notify FSEvents/inotify), HotReloader (shader + params.json)
+- [x] CONTROL_LAYER_README.md: complete instrument wiring example
+
+### Phase 5 — Tauri Shell ✅ COMPLETE
+- [x] Create crates/scheng-tauri
+- [x] Embed scheng-runtime-wgpu in Tauri Rust backend on dedicated thread
+- [x] IPC surface: set_param, load_graph, set_output_mode, start/stop_recording, get_engine_status
+- [x] Preview frame IPC: readback → JPEG (scaled 320×180) → Tauri event ~15fps
+- [x] Instrument template: ui/index.html (param sliders, preview, output mode, recording)
+- [x] macOS: cargo tauri dev confirmed running on Apple M1 Max
+
+
+### First-run: create assets/
+
+The render thread looks for `assets/` relative to CWD.
+Create these two files to get live preview working:
+
+```bash
+mkdir -p assets/shaders
+
+# assets/params.json
+cat > assets/params.json << 'JSON'
+{"version":1,"params":[{"name":"u_speed","min":0,"max":5,"default":1,"smooth":0.05,"midi_cc":1}]}
+JSON
+
+# assets/shaders/default.frag
+cat > assets/shaders/default.frag << 'GLSL'
+#version 330 core
+in vec2 v_uv;
+out vec4 fragColor;
+uniform float uTime;
+void main() {
+    float r = v_uv.x + 0.5 * sin(uTime);
+    float g = v_uv.y + 0.5 * cos(uTime * 0.7);
+    fragColor = vec4(r, g, 0.2, 1.0);
+}
+GLSL
+```
+
+The render thread hot-reloads both files — edit and save while running.
+
+### Phase 6 — Shader Library (LZX-inspired)
+- [ ] Colorizer (hue rotation, RGB↔component)
+- [ ] Ramp generator (H, V, radial, angular)
+- [ ] Luma keyer / chroma keyer
+- [ ] Hard keyer / soft keyer
+- [ ] Proc amp (brightness, contrast, saturation, hue)
+- [ ] Crossfader with T-bar uniform
+- [ ] Matrix mixer 4→1
+- [ ] Video feedback (ping-pong convergence)
+- [ ] Pattern generator (color bars, test card, grid)
+- [ ] Waveform monitor / vectorscope
+
+### Phase 7 — GUI / Editor (design before building)
+- [ ] Node graph editor research
+- [ ] Prototyping → export workflow definition
+- [ ] JSON graph save/load format
+- [ ] Parameter UI contract
+

+
+## Bind Group Layout (bindings 0–5)
+
+| binding | resource | GLSL alias |
+|--------:|---------|------------|
+| 0 | texture2D | iChannel0 |
+| 1 | texture2D | iChannel1 |
+| 2 | texture2D | iChannel2 |
+| 3 | texture2D | iChannel3 |
+| 4 | sampler(filter) | iSampler |
+| 5 | UniformBuffer | FrameBlock (uResolution, uTime, uFrame) |
+
+---
+
+## Architecture Rules (never violate)
+
+1. Engine does not own time — FrameCtx always supplied by host
+2. Topology static after compile() — NodeConfig dynamic
+3. No layer reaches backward — Graph → Runtime → Backend
+4. Control writes NodeConfig/ParamStore only — never touches graph or render loop
+5. Runtime is single-threaded — GPU context on calling thread only
+6. Errors returned immediately — no silent recovery
+7. Optional features truly optional — Syphon/Spout/webcam never in core crates
+8. submit() before present() — sink.present() always after queue.submit()

+//! `compat.rs` — GLSL preprocessor for the wgpu/naga backend.
+//!
+//! shadecore and scheng-runtime-glow use GLSL 330 core with OpenGL conventions.
+//! naga's GLSL frontend targets GLSL 450 with Vulkan-style explicit bindings.
+//!
+//! This module bridges the two. It:
+//!   1. Strips declarations that the compat header provides
+//!   2. Rewrites `iChannel0..3` references to the split texture+sampler form
+//!   3. Prepends the full compat header (version, bindings, aliases)
+//!
+//! # Binding Layout (fixed, matches compat header)
+//!
+//! | Binding | Resource           | GLSL name           |
+//! |--------:|--------------------|---------------------|
+//! |       0 | texture2D          | iChannel0_tex       |

+//! |       2 | texture2D          | iChannel2_tex       |
+//! |       3 | texture2D          | iChannel3_tex       |

+//! # Shader compatibility
+//!
+//! Existing shadecore shaders work unchanged because:
+//! - `iChannel0` → macro expands to `sampler2D(iChannel0_tex, iSampler)`
+//! - `uTime`, `uResolution`, `uFrame` are in FrameBlock
+//! - `u_time`, `u_resolution`, `u_frame` are `#define` aliases

+    <p>scheng is a <strong>Rust engine and SDK</strong> for building programmable video instruments — not a fixed VJ application. It gives you the building blocks: a graph execution model, explicit shader contracts, and a modular I/O surface. You wire them into your own executable.</p>
+
+    <p>The engine is deliberately minimal: it evaluates frames, it does not own time, schedule execution, or manage devices. These responsibilities belong to the <strong>instrument</strong> — your application.</p>

+    <h3>Key architectural principle</h3>
+    <p><strong>Topology is static. Configuration is dynamic.</strong> The graph structure (which nodes connect to which) is fixed after <code>compile()</code>. NodeConfig — shader source, uniforms, input textures — changes every frame. This separation is what makes execution deterministic and debuggable.</p>
+
+    <p>For identical: Graph + NodeConfig + FrameCtx → execution order and resource bindings are always identical. Shader determinism depends on the shader code itself.</p>

+    <span class="anchor" id="troubleshooting"></span>
+    <h2>Troubleshooting</h2>
+
+    <h3>Library not loaded: Syphon.framework</h3>
+    <p>rpath is missing. Verify <code>build.rs</code> has the rpath entries and that <code>scheng/vendor/Syphon.framework</code> exists. Never set <code>DYLD_FRAMEWORK_PATH</code> — rpath makes it unnecessary.</p>
+
+    <h3>MIDI arrives but shader doesn't change</h3>
+    <p>Almost always <code>step_frame()</code> is missing. MIDI writes to <em>targets</em>. The smoother only advances <em>values</em> when <code>step_frame()</code> is called. Both are required every tick.</p>
+    <pre><code>store.step_frame();  <span class="c">// ← without this, store.get() always returns the default</span></code></pre>
+
+    <h3>Custom uniforms are always 0.0</h3>
+    <p>Either (a) the value isn't in <code>NodeConfig.uniforms</code>, or (b) <code>step_frame()</code> isn't called. Check both.</p>
+    <pre><code>cfg.uniforms.insert(<span class="st">"u_threshold"</span>.into(), <span class="nm">0.5</span>);  <span class="c">// must exist</span></code></pre>
+
+    <h3>Webcam is upside down</h3>
+    <p>Missing Y-flip. Always sample webcam textures with inverted V: <code>vec2(v_uv.x, 1.0 - v_uv.y)</code>.</p>
+
+    <h3>Webcam: no compatible format</h3>
+    <p>Camera doesn't support MJPEG at requested resolution. Use <code>--list-cameras</code> to find valid indexes. Try FaceTime HD (usually index 1 on macOS) at 1280×720.</p>
+
+    <h3>Syphon shows zero sources</h3>
+    <p>Run loop not active yet. Defer SyphonReceiver init to frame 5+. See <a href="#syphon-in">Syphon Receive</a>.</p>
+
+    <h3>RTMP: Connection refused</h3>
+    <p>No RTMP server running. Start mediamtx with <code>paths: all_others:</code> config. See <a href="#ffmpeg-out">FFmpeg Output</a>.</p>
+
+    <h3>All pixels black</h3>
+    <p>Output sinks must be called <em>after</em> <code>queue.submit()</code>. This is handled automatically by <code>execute_frame()</code> — don't call <code>present()</code> manually before submitting the command encoder.</p>
+
+    <h3>Shader compile error on startup</h3>
+    <p>Check the log for the GLSL error text. Common causes: GLSL 4.x features not supported by naga (use 3.3 features only), missing <code>void main()</code>, or undeclared variable. The error text includes line numbers relative to the user shader body.</p>

+# scheng instrument example
+
+A minimal but complete instrument built on the scheng SDK.
+Copy this as a starting point for your own instruments.
+
+---
+
+## What it demonstrates
+
+| Feature | How |
+|---------|-----|
+| Shader loading | `assets/shaders/main.frag` loaded at startup |
+| Hot-reload | Edit shader or params.json while running — updates in ~100ms |
+| Live params | `assets/params.json` → MIDI CC + OSC → uniform values |
+| Syphon output | Metal server `"scheng"` — visible in OBS, VDMX, Resolume |
+| FFmpeg output | RTSP stream or local file recording |
+
+---
+
+## Running
+
+```bash
+# Default: Syphon output, no FFmpeg
+cargo run --release
+
+# Stream to RTSP (start mediamtx first: ./mediamtx)
+cargo run --release -- --stream rtsp://localhost:8554/live
+
+# Record to file
+cargo run --release -- --record recording.mp4
+
+# Stream + custom resolution
+cargo run --release -- --stream rtsp://localhost:8554/live --width 1920 --height 1080
+
+# List MIDI ports
+cargo run --release -- --list-midi
+
+# Without Syphon (no framework needed)
+cargo run --release --no-default-features --features midi
+```
+
+---
+
+## Live control
+
+### MIDI CC (any connected controller)
+
+| CC | Parameter | Default |
+|----|-----------|---------|
+| 1  | u_speed (mod wheel) | 1.0 |
+| 7  | u_brightness (volume) | 1.0 |
+| 14 | u_hue_shift | 0.0 |
+
+### OSC (default port 9000)
+
+Send from TouchOSC, Max/MSP, SuperCollider, python-osc, etc.:
+
+```
+/scheng/uniform/u_speed       <float 0–5>
+/scheng/uniform/u_brightness  <float 0–2>
+/scheng/uniform/u_hue_shift   <float -180–180>
+```
+
+Python example:
+```python
+from pythonosc.udp_client import SimpleUDPClient
+c = SimpleUDPClient("127.0.0.1", 9000)
+c.send_message("/scheng/uniform/u_brightness", 0.75)
+```
+
+---
+
+## Hot-reload
+
+Edit `assets/shaders/main.frag` while the instrument is running.
+Save the file — the shader recompiles and updates within ~100ms.
+If the shader has a syntax error, the previous version continues running
+and the error is printed to the console.
+
+Edit `assets/params.json` to add/remove/adjust parameters.
+New parameters appear immediately; existing values are preserved.
+
+---
+
+## Extending this instrument
+
+### Add a new parameter
+
+1. Add a uniform to `assets/shaders/main.frag`:
+   ```glsl
+   uniform float u_zoom;
+   ```
+
+2. Add an entry to `assets/params.json`:
+   ```json
+   {
+     "name":      "u_zoom",
+     "min":       0.5,
+     "max":       2.0,
+     "default":   1.0,
+     "smooth":    0.05,
+     "midi_cc":   15,
+     "osc_addr":  "/scheng/uniform/u_zoom"
+   }
+   ```
+
+That's it. The parameter is now live — MIDI CC 15 and OSC address both work.
+
+### Add a second shader pass
+
+```rust
+// In main.rs:
+let pass_node = graph.add_node(NodeKind::ShaderPass);

+//! `compat.rs` — GLSL preprocessor for the wgpu/naga backend.
+//!
+//! shadecore and scheng-runtime-glow use GLSL 330 core with OpenGL conventions.
+//! naga's GLSL frontend targets GLSL 450 with Vulkan-style explicit bindings.
+//!
+//! This module bridges the two. It:
+//!   1. Strips declarations that the compat header provides
+//!   2. Rewrites `iChannel0..3` references to the split texture+sampler form
+//!   3. Prepends the full compat header (version, bindings, aliases)
+//!
+//! # Binding Layout (fixed, matches compat header)
+//!
+//! | Binding | Resource           | GLSL name           |
+//! |--------:|--------------------|---------------------|
+//! |       0 | texture2D          | iChannel0_tex       |
+//! |       1 | texture2D          | iChannel1_tex       |
+//! |       2 | texture2D          | iChannel2_tex       |
+//! |       3 | texture2D          | iChannel3_tex       |
+//! |       4 | sampler            | iSampler            |

+//! |       6 | UniformBuffer      | CustomBlock (Phase 1.2+) |
+//!
+//! # Shader compatibility
+//!
+//! Existing shadecore shaders work unchanged because:
+//! - `iChannel0` → macro expands to `sampler2D(iChannel0_tex, iSampler)`
+//! - `uTime`, `uResolution`, `uFrame` are in FrameBlock
+//! - `u_time`, `u_resolution`, `u_frame` are `#define` aliases

+//! `scheng-runtime-wgpu`
+//!
+//! A wgpu-based GPU backend for the scheng video synthesis engine.
+//! Implements Metal on macOS, DX12 on Windows, and Vulkan on Linux —
+//! using the same GLSL shader contract as `scheng-runtime-glow`.
+//!
+//! # Architecture
+//!
+//! ```text
+//! scheng-graph  (Plan, NodeId, NodeKind)

+//! # GLSL Compatibility
+//!
+//! User shaders are written in GLSL 330 core (matching shadecore convention).
+//! The `compat` module preprocesses them before naga compilation:
+//!
+//! 1. Strips `#version`, `in vec2 v_uv`, `out vec4 fragColor`, standard uniforms
+//! 2. Replaces `iChannel0..3` references with split texture+sampler form
+//! 3. Prepends the scheng compat header (bindings 0–5)
+//!
+//! This keeps existing shadecore-style shaders working without modification.
+//!
+//! # Quick Start
+//!
+//! ```rust,no_run
+//! use scheng_runtime_wgpu::{WgpuRuntime, NodeConfig, FrameCtx};
+//! use scheng_graph::{Graph, NodeKind};
+//! use std::collections::HashMap;
+//!
+//! // Build a graph

+//! let src = g.add_node(NodeKind::ShaderSource);
+//! let out = g.add_node(NodeKind::PixelsOut);
+//! g.connect_named(src, "out", out, "in").unwrap();
+//! let plan = g.compile().unwrap();
+//!
+//! // Create the runtime (blocking, initialises GPU device)
+//! let mut runtime = WgpuRuntime::new(1280, 720).unwrap();
+//!
+//! // Configure nodes (use builtin shaders for src)
+//! let mut configs: HashMap<_, _> = HashMap::new();
+//! configs.insert(src, NodeConfig::default());
+//! configs.insert(out, NodeConfig::default());
+//!
+//! // Run one frame
+//! let ctx = FrameCtx { width: 1280, height: 720, time: 0.0, frame: 0 };
+//! runtime.execute_frame(&plan, &configs, &ctx).unwrap();

+//! `uniforms.rs` — GPU uniform buffer management.
+//!
+//! The compat header declares a `FrameBlock` uniform buffer at binding 5:
+//! ```glsl
+//! layout(binding = 5) uniform FrameBlock {
+//!     vec2  uResolution;
+//!     float uTime;
+//!     uint  uFrame;
+//! };
+//! ```
+//!
+//! This module maintains a single `wgpu::Buffer` for this block and writes
+//! updated values from [`FrameCtx`] before each draw call.
+//!
+//! # Memory layout (std140)
+//!
+//! GLSL uniform blocks use std140 layout rules:
+//! - `vec2`  → 8 bytes (2 × f32)
+//! - `float` → 4 bytes
+//! - `uint`  → 4 bytes
+//! Total: 16 bytes. The struct below matches this exactly.
+//!

+# scheng-gradient
+
+Minimal [scheng](https://github.com/your-org/scheng) instrument.
+
+Opens a window and hot-reloads a GLSL fragment shader from `assets/shaders/main.frag`.
+Edit and save the shader — the output updates immediately.
+
+## Requirements
+
+- Rust 1.75+
+- macOS (Metal) / Windows (DX12) / Linux (Vulkan)
+- macOS only: `vendor/Syphon.framework` in the scheng workspace (for Syphon I/O)
+
+## Setup
+
+1. Clone scheng next to this project:
+   ```
+   projects/
+     scheng/
+     scheng-gradient/    ← this project
+   ```
+
+2. Build and run:
+   ```bash
+   cargo run --release
+   ```
+
+## Run options
+
+```bash
+# Custom resolution
+cargo run --release -- --width 1920 --height 1080
+
+# 4K
+cargo run --release -- --width 3840 --height 2160
+
+# 4K + MSAA 4x anti-aliasing
+cargo run --release -- --width 3840 --height 2160 --msaa 4
+
+# Stream to RTMP (requires mediamtx or similar)
+cargo run --release -- --stream rtmp://localhost:1935/live/key
+
+# Stream to RTSP
+cargo run --release -- --stream rtsp://localhost:8554/live
+
+# Record to file
+cargo run --release -- --record output.mp4
+```
+
+## Shader
+
+Edit `assets/shaders/main.frag` — changes are picked up live.
+
+Available built-in uniforms:
+| Uniform | Type | Description |
+|---------|------|-------------|
+| `uTime` | `float` | Seconds since start |
+| `uFrame` | `float` | Frame counter |
+| `uResolution` | `vec2` | Width × height in pixels |
+| `iChannel0–3` | `sampler2D` | Input textures (when I/O enabled) |
+
+Custom `u_*` uniforms are automatically exposed via OSC and MIDI CC.
+
+## Adding I/O
+
+Uncomment the relevant sections in `Cargo.toml` and `src/main.rs`:
+
+| Feature | What it enables |
+|---------|----------------|
+| `midi`  | MIDI CC → uniform control |
+| `osc`   | OSC → uniform control |
+| `syphon` | Syphon output (macOS) |
+| `stream` | RTMP/RTSP/file output |
+
+## Architecture
+
+```
+assets/shaders/main.frag
+        ↓ hot-reload
+   ShaderSource node
+        ↓ wgpu render
+   PixelsOut node
+        ↓
+   PreviewSink → window

+# scheng-mixer
+
+Two-channel video mixer built on the scheng SDK.
+
+Accepts two Syphon inputs, crossfades between them via MIDI T-bar, outputs via Syphon.

+//! `tests/headless.rs` — integration tests for scheng-runtime-wgpu.
+//!
+//! These tests run the full pipeline (context → shader → render → readback)
+//! on actual GPU hardware. They are skipped gracefully if no GPU adapter
+//! is available (common in CI without a GPU).
+//!
+//! # Running
+//!
+//! ```sh
+//! # Run all headless tests with output visible
+//! cargo test -p scheng-runtime-wgpu -- --nocapture
+//!
+//! # Run a single test
+//! cargo test -p scheng-runtime-wgpu test_single_node_renders -- --nocapture
+//!
+//! # Force software rendering (WGPU_POWER_PREF=none and Vulkan software on Linux)
+//! WGPU_BACKEND=gl cargo test -p scheng-runtime-wgpu -- --nocapture
+//! ```
+//!
+//! # What these tests verify
+//!
+//! 1. `test_compat_preprocessing` — pure CPU: compat.rs strips/rewrites correctly
+//! 2. `test_naga_glsl_compile`     — GPU-free: naga parses a processed shader
+//! 3. `test_context_init`          — GPU: WgpuContext::new() succeeds
+//! 4. `test_single_node_renders`   — GPU: ShaderSource → PixelsOut, pixel readback
+//! 5. `test_two_node_pipeline`     — GPU: ShaderSource → ShaderPass → PixelsOut
+//! 6. `test_uniform_time_varies`   — GPU: uTime changes between frames
+//! 7. `test_blank_texture_safety`  — GPU: unconnected iChannelN → black, not crash
