Superseded by `CORRECTION_REPORT.md` and the production Capture V2 implementation. Numeric R1/R2, encoder, hardware, and speed claims below are not current public product claims. + +--- + +## Executive Summary + +To modernize the Nexus Unity screenshot capture pipeline without altering external JSON-RPC wire contracts, an experimental spike program was executed across Spikes A through E. The goal was to replace synchronous main-thread screen-scraping and managed `Texture2D` allocations with an asynchronous, non-blocking pipeline utilizing `AsyncGPUReadback` and native `ImageConversion` encoding. + +All benchmarks were implemented in `Editor/MCPServerMethods.CaptureSpikes*.cs` and evaluated against the live, active Unity Editor instance. + +### Primary Conclusions + +1. **Thread Model (Spike A)**: The asynchronous JSON-RPC dispatch model via `TaskCompletionSource` with `TaskCreationOptions.RunContinuationsAsynchronously` is fully validated. The main thread is never blocked (`.Wait()`, `.Result`, and `WaitForCompletion()` were completely avoided). All Base64 encoding and JSON-RPC serialization execute off-thread on background ThreadPool workers. +2. **Game View Acquisition (Spike B)**: Option B (Reflected `m_RenderTexture` blit into a Nexus-owned `RenderTexture`) successfully acquires frames across all conditions (Edit Mode, Play Mode, focused, unfocused, and hidden/docked) in $< 0.1\text{ ms}$, completely avoiding camera re-rendering and isolating readbacks from window lifecycle changes. +3. **Normalized RenderTexture & Metal Constraints (Spike C)**: Submitting a GPU blit on Metal takes $\approx 0.0013\text{ ms}$. `AsyncGPUReadback` naturally outputs top-to-bottom coordinates matching PNG/JPEG image space without requiring a vertical Y-flip. However, **Metal GPU command encoders reject unaligned buffer copies**; normalized RTs must maintain 4-byte / even-pixel width boundaries. +4. **Encoder Performance (Spike D)**: `ImageConversion.EncodeNativeArrayToPNG` produces bit-for-bit identical outputs to `Texture2D.EncodeToPNG` with zero GC allocation. `ImageConversion.EncodeNativeArrayToJPG` (quality 85) is **$3.5\times$ faster** ($8.34\text{ ms}$ vs $28.28\text{ ms}$) with a $14\%$ smaller payload. +5. **R1 vs R2 Readback (Spike E)**: **R1 (`AsyncGPUReadback.Request` + `GetData()`) is selected.** `GetData()` was proven to be a **zero-allocation, sub-microsecond ($0.0002\text{ ms}$) view** directly accessing the native driver ring buffer. R2 (persistent native array) saves only $0.7\text{ ms}$ but introduces complex buffer lifecycle and resizing state. +6. **Primary Bottleneck**: Single-threaded PNG compression accounts for **$71\%$ of total capture latency** and **$98\%$ of main-thread stall time**. Adopting native JPEG immediately reduces total latency by $50\%$ and main-thread stall by $70\%$. + +--- + +## 1. Spike A: Async RPC Lifecycle & Thread ID Trace + +### Implementation Architecture + +- Incoming HTTP JSON-RPC POST requests arrive at the `MCPServer.Http` worker pool. +- A `TaskCompletionSource` is initialized with `TaskCreationOptions.RunContinuationsAsynchronously`. +- Main thread operations (source acquisition, normalization blit, `AsyncGPUReadback.Request`) are enqueued via `MCPServer.Enqueue()`. +- Frame completion is monitored non-blockingly inside `EditorApplication.update` callbacks. +- When `request.done == true`, native compression runs on the main thread and populates a managed `byte[]` compatibility buffer. +- `tcs.SetResult` completes the task. Because continuations are asynchronous, `SetResult` returns immediately without executing the continuation on the main thread. +- The HTTP worker thread resumes asynchronously, performs Base64 conversion and JSON serialization, and writes the HTTP response. + +### Measured Thread Trace & Latency Breakdown + +| Step | Pipeline Stage | Thread ID | Thread Type | Timestamp / Latency | +| :---: | :--- | :---: | :--- | :--- | +| **1** | HTTP request received | `210` | Worker ThreadPool | $t = 0.0134\text{ ms}$ | +| **2** | Main action dispatched & start | `1` | Unity Main Thread | $t = 0.2020\text{ ms}$ (queue delay: $0.1886\text{ ms}$) | +| **3** | Source acquisition complete | `1` | Unity Main Thread | $t = 0.3037\text{ ms}$ (duration: $0.1017\text{ ms}$) | +| **4** | Readback request issued | `1` | Unity Main Thread | $t = 0.3074\text{ ms}$ | +| **5** | Readback done (update tick poll) | `1` | Unity Main Thread | $t = 10.4973\text{ ms}$ (3 frames elapsed @ 60 FPS) | +| **6** | `ImageConversion` PNG encoding | `1` | Unity Main Thread | duration: $28.6881\text{ ms}$ | +| **7** | `tcs.SetResult` invoked | `1` | Unity Main Thread | $t = 39.4931\text{ ms}$ | +| **8** | Main thread post-TCS execution | `1` | Unity Main Thread | $t = 39.5149\text{ ms}$ ($0.0218\text{ ms}$ return time) | +| **9** | Continuation resumed | `208` | Worker ThreadPool | $t = 39.5436\text{ ms}$ | +| **10**| Base64 string encoding | `208` | Worker ThreadPool | duration: $0.2672\text{ ms}$ ($51,560\text{ chars}$) | +| **11**| HTTP response flushed | `208` | Worker ThreadPool | **Total Latency: $39.8291\text{ ms}$** | + +### Proof of Non-Blocking Execution + +- `proof_main_thread_never_blocked`: **`true`**.

This completely decouples the capture from Unity's internal GameView lifecycle: if the GameView window is resized, minimized, or closed while `AsyncGPUReadback` is in flight, the Nexus-owned RT remains valid and uncorrupted. + +--- + +## 3.

R1 achieves $1.31\text{ ms}$ wait latency, $0.0001\text{ ms}$ `GetData()` duration, $0$ managed memory allocation, and total immunity from persistent buffer management bugs across dynamic resolutions. +3. **Format & Encoding:** **Native JPEG at Quality 85** (`ImageConversion.EncodeNativeArrayToJPG(raw, format, w, h, 0, 85)`). This delivers a **$2.9\times$ roundtrip speedup**, a **$68\%$ reduction in Editor main-thread freeze**, and a **$65\%$ reduction in wire payload**, while preserving $>39\text{ dB}$ PSNR on fine text. +4. **Resolution Policy:** Default to full Game View resolution (P2). For high-frequency agent polling or 4K monitors, offer optional 1600x900 normalization (P3), which further cuts latency to $15.31\text{ ms}$ and Editor freeze to $6.37\text{ ms}$. + +--- + +## Section Q: Remaining Bottleneck Analysis + +In the selected P2 pipeline ($17.16\text{ ms}$ roundtrip): +1. **Native JPEG Encoding ($8.94\text{ ms}$, 52% of total):** Remains the single largest component. Because `ImageConversion` runs on the Unity main thread, it accounts for nearly all of the remaining $8.97\text{ ms}$ main-thread freeze. +2. **GPU Readback Wait ($5.31\text{ ms}$, 31% of total):** Asynchronous GPU-to-CPU transfer over the Metal command queue. Completely non-blocking to the Editor main thread. +3. **HTTP / JSON / Base64 Transport ($2.88\text{ ms}$, 17% of total):** Base64 string construction ($0.07\text{ ms}$) and local HTTP transport ($2.8\text{ ms}$). + +**Next Optimization Target:** Moving JPEG encoding off the Unity main thread onto a background worker thread (via native libjpeg-turbo C-ABI plugin or Rust sidecar) would reduce Editor main-thread stall from $8.97\text{ ms}$ down to $<0.5\text{ ms}$. + +--- + +## Section 38: Required Final Decisions + +### 1. Readback: R1 vs R2 +- **Decision:** **R1 (`AsyncGPUReadback.Request`)** +- **Evidence:** R1 wait latency ($p50 = 1.31\text{ ms}$) is only $0.32\text{ ms}$ behind R2 ($0.99\text{ ms}$). `GetData()` on R1 costs only **$0.0001\text{ ms}$** with $0\text{ bytes}$ GC allocation. R1 completely avoids preallocated buffer lifetime tracking, disposal leaks, and dynamic resolution race conditions. + +### 2. Game View Source: Public vs Reflected +- **Decision:** **Reflected (`m_RenderTexture` Blit)** +- **Evidence:** Public API (`ScreenCapture.CaptureScreenshotIntoRenderTexture`) **fails in Edit Mode ($0\%$ success, $100\%$ stale)**. Reflected blit achieved **$100.0\%$ success, $0.0\%$ stale, and $0.0\%$ black frames** across all 12 editor states with $0.025\text{ ms}$ acquisition latency. + +### 3. Normalization +- **Decision:** **Direct 1:1 Blit for native capture; optional bilinear downscale for 4K** +- **Evidence:** CPU blit submission takes $0.01\text{–}0.03\text{ ms}$. Storing in a Nexus-owned RT isolates the readback from window resize/aspect changes. + +### 4. Metal Alignment +- **Decision:** **Contiguous stride standard; padded width supported via explicit stride** +- **Evidence:** Metal 4 on Apple Silicon delivered $450/450$ passes across all widths with contiguous rows (`mod_4 == 0` is not strictly enforced by the driver for 2D readback). Padded physical RT testing confirmed that passing explicit stride into `ImageConversion` works reliably when padding is present. + +### 5. PNG Path +- **Decision:** **Retain Native PNG only for explicit lossless requests (`format: "png"`)** +- **Evidence:** Native PNG requires $26.7\text{ ms}$ on text UI and **$76.9\text{ ms}$ on textured gameplay**, freezing the main thread for the entire duration. + +### 6. JPEG Path +- **Decision:** **Native JPEG Quality 85** +- **Evidence:** Encodes in $8.7\text{–}10.2\text{ ms}$ ($8\times$ faster than PNG on gameplay), achieves $39.1\text{ dB}$ PSNR on text UI and $46.6\text{ dB}$ on gameplay, while shrinking wire size by $75\%\text{–}91\%$. + +### 7. Resolution +- **Decision:** **Full resolution default; 1600x900 option** +- **Evidence:** 1600x900 downscale reduces Python roundtrip to $15.31\text{ ms}$ and main-thread stall to $6.37\text{ ms}$ with negligible loss in vision model comprehension. + +### 8. Managed Allocations +- **Decision:** **$0.61\text{ MB}$ per capture (down from $23.57\text{ MB}$)** +- **Evidence:** Eliminates `Texture2D` and `ReadPixels` allocations completely. Remaining allocations are strictly the compressed `.ToArray()` byte buffer and Base64 JSON wire payload. + +### 9. Main-Thread Stall +- **Decision:** **$8.97\text{ ms}$ in V2 (down from $28.09\text{ ms}$ in V1, a $68\%$ reduction)** +- **Evidence:** Measured across 100 samples in P2 ($8.97\text{ ms}$) and P3 ($6.37\text{ ms}$) vs P0 ($28.09\text{ ms}$). + +### 10. End-to-End Roundtrip +- **Decision:** **$17.16\text{ ms}$ p50 (down from $50.14\text{ ms}$ in V1, a $2.9\times$ speedup)** +- **Evidence:** Measured externally from Python monotonic timestamps across 100 requests. + +### 11. Reliability +- **Decision:** **$100.0\%$ success rate, $0.0\%$ stale rate, $0.0\%$ black frames** +- **Evidence:** Validated across 720 multi-condition samples using deterministic color-encoded frame sequence markers. + +### 12. Remaining Bottleneck +- **Decision:** **Main-thread JPEG encoding ($8.94\text{ ms}$, 52% of total pipeline)** +- **Evidence:** Identified as the next optimization target (off-thread background encoding). diff --git a/Research~/docs/CORRECTION_REPORT.md b/Research~/docs/CORRECTION_REPORT.md new file mode 100644 index 0000000..f80e75c --- /dev/null +++ b/Research~/docs/CORRECTION_REPORT.md @@ -0,0 +1,167 @@ +# Historical Correction Report: Nexus Unity vs. Unity CLI / Pipeline / MCP + +> Historical research archive.

The earlier impression that Unity CLI / Pipeline was "100x slower" was caused entirely by cold process startup overhead (spawning a fresh CLI process per command), not transport protocol inefficiencies. + +--- + +## Section 5: Explicit Corrections to Previous Report + +The following claims in previous reports were incorrect, confounded, or based on mistaken API identification, and are formally corrected: + +1. **The "177x Faster" Claim (Retracted)**: + - *Previous claim*: Nexus capture is $177\times$ faster than official Unity capture ($5.78\text{ ms}$ vs. $1026.09\text{ ms}$). + - *Why invalid*: The comparison contrasted an internal in-engine timestamp ($5.78\text{ ms}$) of Nexus JPEG against a cold-spawned CLI invocation of Unity CLI ($1026\text{ ms}$) that incurred operating system process creation, .NET assembly discovery, and socket setup overhead on every call. + - *Correct ratio*: Under fair, warm persistent conditions at identical resolution and format ($1280 \times 720$ PNG), Nexus roundtrip is **$1.10\times$ faster** ($143.14\text{ ms}$ vs. $157.33\text{ ms}$), and in-engine execution is **$1.32\times$ faster** ($43.34\text{ ms}$ vs. $57.13\text{ ms}$). In the product fast-path (JPEG Q85 vs. PNG), Nexus roundtrip is **$1.54\times$ faster** ($102.34\text{ ms}$ vs. $157.33\text{ ms}$). +2. **The "13.3x Smaller Payload" Claim (Retracted)**: + - *Previous claim*: Nexus produces payloads $13.3\times$ smaller than official Unity capture ($17.5\text{ KB}$ vs. $232.3\text{ KB}$). + - *Why invalid*: The comparison contrasted a lossy 720p JPEG at Quality 85 against an uncompressed, high-DPI full-resolution PNG. + - *Correct ratio*: At identical $1280 \times 720$ resolution in PNG, Nexus payload is **$2.56\times$ smaller** ($112.9\text{ KB}$ vs. $289.5\text{ KB}$). In the product fast-path (JPEG Q85 vs. PNG), the payload is **$6.67\times$ smaller** ($43.4\text{ KB}$ vs. $289.5\text{ KB}$). +3. **Readback Backend Terminology & Classification**: + - *Previous report*: Inverted the naming convention and erroneously asserted that the production pipeline was using preallocated pinned native arrays with zero GC allocations. + - *Correction*: The production candidate uses `DriverOwnedReadback` (`AsyncGPUReadback.Request(rt) -> req.GetData()`). It does not preallocate arrays. The legacy shorthand labels are permanently retired. +4. **Hardware JPEG Encoding on Apple Silicon (Retracted)**: + - *Previous claim*: Asserted that `ImageConversion.EncodeNativeArrayToJPG` utilized hardware VideoToolbox ASIC encoders on Apple Silicon. + - *Correction*: Unity's `ImageConversion` uses libjpeg-turbo running on CPU cores with ARM NEON SIMD vectorization. It is CPU-bound, not GPU/ASIC hardware-accelerated. +5. **Unity MCP Screenshot Capabilities (Corrected)**: + - *Previous claim*: Claimed Unity MCP does not support screenshots. + - *Correction*: Unity MCP *does* support `capture_game_view` and `capture_scene_view`. However, its implementation is limited to camera rendering (`Camera.Render()`), causing main-thread stalls of $\sim 48.6\text{ ms}$ and completely omitting Screen Space - Overlay Canvas UI. + +--- + +## Section 6: Architecture Evidence Gate + +1. **Does Unity CLI / Pipeline / MCP provide acceptable performance for core commands (hierarchy, compile, inspect) under warm persistent connections?** + **YES**. Under persistent stdio MCP (`unity mcp`), command dispatch overhead is within $2\text{--}4\text{ ms}$ of native HTTP loopback ($p50 \approx 101\text{--}102\text{ ms}$). Performance is fully production-grade. + +2. **Does Nexus capture provide a meaningful advantage over Unity capture when compared fairly?** + **YES**. While the roundtrip speedup is modest ($1.10\times\text{--}1.54\times$), the **functional and architectural advantages are critical**: + - Nexus captures Screen Space - Overlay UI; official Unity capture fails completely. + - Nexus main-thread stall is **$1.59\text{ ms}$** vs. **$\sim 48.60\text{ ms}$** for official capture ($30.6\times$ reduction in editor freeze). + - Nexus offers configurable JPEG encoding ($43.4\text{ KB}$ vs. $289.5\text{ KB}$ bandwidth). + +3. **Is that capture advantage worth maintaining a custom HTTP server?** + **NO**. The capture pipeline's advantage is entirely an in-engine C# rendering and readback optimization (`AsyncGPUReadback` + `NativeArray` encoding). It does not require a custom HTTP networking stack, custom thread pools, or custom port discovery logic. + +4. **Can Nexus capture be delivered as a Pipeline extension instead of standalone HTTP?** + **YES**. Nexus Capture V2 has been validated as a `com.unity.pipeline` `[CliCommand]` extension (`nexus_capture_game_view`). Under persistent `unity mcp`, it executes with only a $+14.6\text{ ms}$ delta over direct HTTP ($111.67\text{ ms}$ vs. $97.03\text{ ms}$) while retaining full async GPU readback and overlay UI fidelity. + +5. **Does the desktop fallback claim hold up under verification?** + **NO**. Verified across 5 empirical trials with a frozen main thread. Unity MCP blocked on the dispatcher queue until the main thread awoke, and direct package inspection confirmed no desktop fallback mechanism exists. diff --git a/Research~/docs/NEXUS_UNITY_ARCHITECTURE_EVALUATION.md b/Research~/docs/NEXUS_UNITY_ARCHITECTURE_EVALUATION.md new file mode 100644 index 0000000..9ac042f --- /dev/null +++ b/Research~/docs/NEXUS_UNITY_ARCHITECTURE_EVALUATION.md @@ -0,0 +1,265 @@ +# Nexus Unity Architecture Evaluation & Strategic Positioning Report +## Empirical Evaluation of Nexus Unity vs. Official Unity CLI / Pipeline / MCP Stack + +**Correction (2026-09-22):** Do not quote **177× faster** or **13.3× smaller** as fair capture-engine claims.

What is the real cost of each stage of the current V1 pipeline? +The legacy V1 pipeline operates synchronously on the Unity main thread: +- **Source Acquisition (Surface Read / Reflection)**: $1.2\text{--}3.5\text{ ms}$ +- **Synchronous Texture Read (`ReadPixels`)**: $12.4\text{--}24.8\text{ ms}$ (CPU/GPU synchronization stall) +- **Synchronous CPU PNG Encode (`ImageConversion.EncodeToPNG`)**: $18.5\text{--}42.1\text{ ms}$ +- **Total Main-Thread Stall**: **$32.1\text{--}70.4\text{ ms}$** +- **Total Request Latency**: $35\text{--}85\text{ ms}$ +- **Wire Payload Size**: $180\text{--}350\text{ KB}$ (lossless PNG) + +### 2. What is the real cost of each stage of Capture V2? +Capture V2 decouples source blitting, asynchronous GPU readback, and background-friendly encoding: +- **Source Acquisition (`reflected:GameView`)**: $0.05\text{ ms}$ ($p50$) +- **GPU Readback Submit (`AsyncGPUReadback.Request`)**: $0.0025\text{ ms}$ ($p50$) +- **GPU In-Flight Async Wait**: $6.8\text{--}8.2\text{ ms}$ (exactly 2–3 Editor ticks, non-blocking) +- **Managed Memory Transfer (`GetData()`)**: $0.001\text{ ms}$ ($p50$) +- **Encoding (`ImageConversion.EncodeToJPG` Q85)**: $1.53\text{ ms}$ ($p50$) +- **Total Main-Thread Stall**: **$1.59\text{ ms}$** ($p50$) +- **Total Request Roundtrip**: **$5.78\text{ ms}$** ($p50$) +- **Wire Payload Size**: **$17.48\text{ KB}$** ($p50$) + +### 3. Is R1 or R2 actually faster, and by how much? +**R1 (`AsyncGPUReadback.RequestIntoNativeArray`) is faster and superior to R2 (`AsyncGPUReadback.Request`)**. +- **Latency**: R1 achieves $10.88\text{ ms}$ ($p50$) total time vs $12.30\text{ ms}$ for R2 (a **13.1% speedup**). +- **Garbage Collection Overhead**: R1 preallocates and reuses a pinned `NativeArray`, yielding **$0\text{ B}$ GC alloc** on the readback path. R2 allocates an internal `AsyncGPUReadbackRequest` managed wrapper on every request. + +### 4. What does `GetData()` really cost at the recommended production configuration? +In the recommended production configuration (**R1 + JPEG Q85**): +- `GetData()` cost is **$0.001\text{ ms}$ ($1\text{ microsecond}$)**. Because R1 writes directly into the caller's preallocated `NativeArray`, no conversion or memory copying occurs when retrieving pixel data. + +### 5. Does the choice of R1 vs R2 change which encoder is best? +**No**. Hardware-accelerated managed JPEG (`ImageConversion.EncodeToJPG` at quality 85) is universally superior across both R1 and R2: +- Encoding time is $1.53\text{ ms}$ for JPEG vs $8.5\text{--}11.2\text{ ms}$ for PNG. +- Payload is $17.5\text{ KB}$ for JPEG vs $138.1\text{ KB}$ for PNG (7.9x bandwidth savings). + +### 6. Does the choice of encoder change which readback path is best? +**No**. R1 remains optimal regardless of encoder because R1 operates on the GPU transfer stage, while encoding operates on the completed byte buffer. + +### 7. What is the actual performance of the official Unity CLI / Pipeline / MCP capture? +Official Unity capture is severely unoptimized: +- `capture_game_view` roundtrip latency: **$1026.09\text{ ms}$ ($p50$)**, Mean: $1042.10\text{ ms}$, Min: $935.08\text{ ms}$, Max: $1257.19\text{ ms}$. +- `screenshot` (disk file return) latency: **$1003.66\text{ ms}$ ($p50$)**, Mean: $1010.09\text{ ms}$. +- Main-thread stall: $25\text{--}80\text{ ms}$. +- Payload size: $232,269\text{ bytes}$ ($232.3\text{ KB}$). + +### 8. How does official Unity capture compare to Nexus V1 and Nexus Capture V2? + +| Dimension | Nexus V1 (Legacy) | Official Unity (`capture_game_view`) | Nexus Capture V2 (R1 + JPEG Q85) | V2 Advantage vs Official | +| :--- | :--- | :--- | :--- | :--- | +| **Roundtrip Latency ($p50$)** | $45.2\text{ ms}$ | $1026.09\text{ ms}$ | **$5.78\text{ ms}$** | **177x Faster** | +| **Main-Thread Stall** | $32.1\text{ ms}$ | $48.6\text{ ms}$ | **$1.59\text{ ms}$** | **30x Less Stall** | +| **Wire Payload Size** | $210\text{ KB}$ | $232.3\text{ KB}$ | **$17.48\text{ KB}$** | **13.3x Smaller** | +| **Screen Space UI Support** | Partial (playmode only) | **0% (Fails completely)** | **100% (Edit & Play Mode)** | **Complete Parity** | +| **Format Flexibility** | PNG only | PNG only | JPEG (Q1–Q100) & PNG | **Full Control** | +| **GC Allocations** | $1.2\text{ MB}$ / frame | $2.4\text{ MB}$ / frame | **$0\text{ B}$ (steady state)** | **Zero GC Pressure** | + +### 9. Does official Unity capture support Screen Space - Overlay UI, Canvas elements, Gizmos, handles, and editor windows? +**NO**: +- **Screen Space - Overlay UI**: Missing entirely. `capture_game_view` renders via `Camera.Render()`, which operates in world space before overlay canvases are composited. `source="screen"` throws `InvalidOperationException: Screen source is only available in Play Mode`. +- **Gizmos, Handles & Grid**: Missing. Scene View capture in official Unity (`capture_scene_view`) calls `SceneView.camera.Render()`, completely skipping editor gizmos, selection outlines, and handle visuals. +- **Editor Windows (Inspector, Hierarchy)**: Official Unity has **zero** tools to capture Inspector, Hierarchy, or arbitrary Editor windows. + +### 10. Is the official Unity CLI / Pipeline / MCP stack viable as a transport / foundation for Nexus? +**YES, as a transport and lifecycle substrate**, with one critical architectural caveat: +- **Viable**: Unity Pipeline's C# server (`com.unity.pipeline`) and stdio MCP server (`unity mcp`) are rock-solid ($1.35\text{ ms}$ $p50$ command overhead).

Loss of Screen Space - Overlay UI and Canvas elements. + 3. Loss of Inspector, Hierarchy, and Editor window visual captures. + 4. $13.3\text{x}$ larger wire payloads ($17.5\text{ KB}$ vs $232.3\text{ KB}$). + 5. Severe main-thread freezing ($48\text{ ms}$ freeze vs $1.59\text{ ms}$). + +### Decision Question 3: What is the recommended positioning of Nexus Unity relative to the official Unity CLI? +**Verdict: COMPLEMENTARY HIGH-LEVEL AGENT INTELLIGENCE & ACCELERATED CAPTURE SUITE.** +- **Positioning Statement**: + *"Unity CLI provides the atomic pipes; Nexus Unity provides the brain and the eyes."* + - **Unity CLI / Pipeline**: Handles low-level engine transport, assembly recompilation, test running, and atomic object transforms. + - **Nexus Unity**: Provides high-level project intelligence maps, de-duplicated compiler diagnostics, UI Toolkit visual layout inspection, and millisecond-grade GPU readback capture. + +### Decision Question 4: What is the migration roadmap if adopting Unity Pipeline? +1. **Milestone 1 (Immediate - Production Freeze)**: Ship Nexus Capture V2 (R1 + JPEG Q85) within the current Nexus architecture to resolve all capture latency and main-thread stall issues. +2. **Milestone 2 (Dual-Registration)**: Annotate high-value Nexus tools with `[CliCommand]` (as proven in `NexusHybridCommands.cs`). This allows users with `com.unity.pipeline` installed to access Nexus tools directly via `unity command` and `unity mcp`. +3. **Milestone 3 (Transport Unification)**: Once Unity CLI reaches General Availability ($1.0.0$ stable), deprecate the standalone Python bridge and native HTTP server in favor of `unity mcp` carrying Nexus commands. + +### Decision Question 5: What are the open risks, unknowns, and blockers? +1. **`unity shell` SIGSEGV Bug**: `unity shell --protocol ndjson` in `1.0.0-beta.10` crashes with `SIGSEGV` (signal 11) after 3–4 large payload writes ($>200\text{ KB}$). While stdio `unity mcp` does not suffer from this bug, persistent shell usage is currently unsafe for image streaming. +2. **Token Window Bloat**: Exposing 151 official tools plus 50 Nexus tools consumes $\sim 30,000$ tokens ($\sim 15\%$ of a 200k context window). Nexus must implement tag-based or profile-based tool masking. +3. **Preview Package Dependency**: `com.unity.pipeline` is currently experimental (`0.7.0-exp.1`). Tying Nexus strictly to this package would prevent users on older Unity versions (e.g. Unity 2022 LTS) from using Nexus. + +--- + +## Artifact Manifest + +The complete machine-readable benchmark datasets and captured media are committed and available at: +- **Benchmark Summary CSV**: `architecture-benchmark-results.csv` +- **Full Benchmark JSON Dataset**: `architecture-benchmark-results.json` +- **Agent Tasks Benchmark JSON**: `agent-tasks-benchmark.json` +- **T1/T2 Validation Results**: `capture-validation-results.json` +- **Official CLI Commands Manifest**: `unity-cli-commands.json` +- **Official Pipeline Commands Manifest**: `unity-pipeline-commands.json` +- **Official MCP Tools Manifest**: `unity-mcp-tools.json` +- **Nexus MCP Tools Manifest**: `nexus-mcp-tools.json` +- **Hybrid POC Implementation**: `Editor/NexusHybridCommands.cs` +- **T1/T2 Benchmark Test Implementation**: `Editor/CaptureValidation.T1T2.cs` +- **Benchmark Execution Harnesses**: `scripts/run-architecture-benchmark.py`, `scripts/benchmark-agent-tasks.py` +- **Reference Output Captures**: `captures/nexus_game_view_v2.jpg`, `captures/nexus_game_view_v2.png`, `captures/unity_screenshot_game.png` diff --git a/Research~/notes/editor-tick-cadence.md b/Research~/notes/editor-tick-cadence.md new file mode 100644 index 0000000..cf0971b --- /dev/null +++ b/Research~/notes/editor-tick-cadence.md @@ -0,0 +1,23 @@ +# Backlog: Editor update cadence vs capture submit→done + +Historical in-engine Capture V2 measurement (active Editor): + +- submit→done ≈ 6–8 ms +- about 3 `EditorApplication.update` ticks + +Stabilization persistent MCP + HTTP, same session, idle/focused Game View: + +- submit→done p50 ≈ 297–299 ms +- exactly 3 `EditorApplication.update` ticks +- stall p50 ≈ 10–18 ms + +This is **not** a Pipeline-specific tax.
