UrlLib supplies data-URL GET +decoding, missing response Content-Type handling, and byte-preserving Windows +POST bodies with case-insensitive Content-Type handling; these changes are in +[BabylonJS/UrlLib#39](https://github.com/BabylonJS/UrlLib/pull/39). +An override is a local integration experiment, not a dependency-pin update. +Results against those sources must not be attributed to the default pins. + +NativeDawn Canvas2D uses real NanoVG/Dawn rasterization and straight-RGBA GPU +readback for getImageData, PNG encoding, and external-image uploads. Backend +initialization and mapping failures are explicit errors; there is no blit-only +or fake-image fallback. The WebGPU validation runner initializes unready +DynamicTexture canvases with an actual texture update before waiting for +material readiness, avoiding a GUI initialization cycle without forcing ready +flags or advancing test render frames. + +Canvas gradients interpolate straight RGBA stops, as verified against Chrome; +premultiplication happens during painting, not while interpolating the ramp. +Dawn text measurement uses the shared Canvas glyph advances and ink/font +extents for the same loaded face used by drawing, rather than estimated Arial +widths. Font state is restored together with NanoVG state. The standalone Dawn +regression uses the existing Droid Sans test fixture copied under `Scripts`, +so its font checks do not depend on a network download. + +Accurate Canvas metrics also expose a Babylon.js headless font-layout difference: +its canvas-only `getFontOffset` fallback currently prefers `Hg` ink extents, +whereas its DOM path measures the font line box. The canonical upstream +correction prefers a complete usable font-bounds pair, with ink bounds and the +CSS-size estimate retained as fallbacks. A source-generated backport into an +isolated 9.21.2 consumer passes the original GUI subset; the default bundle and +dependency pins remain unchanged. Preserve the upstream patch, backport script, +bundle hash and executable identity when reproducing this experiment. These +consumer results are not a permanent plugin workaround or evidence that the +default Babylon.js catalog passes. + +For the Lite smoke test, install dependencies and run `pnpm build:lib` in a +Babylon-Lite clone, using its declared Node and pnpm versions. From this repository, +run `node .github\scripts\bundle-lite-scene.mjs scene1 \Scripts\scene1.playground.js` +and copy `\lab\public\brdf-lut.png` to `\Scripts`. +Then run `.\Playground.exe --headless app:///Scripts/lite_native.js`. Only the Lite +harness redirects lab root-relative asset URLs to `app:///Scripts`; the plugin +does not rewrite application fetches. + +NativeDawn's typed `Tick` and `ResizeSurface` APIs drive frames and the presentation +canvas; they do not look up global `frame` or `__dawnResize` functions. Babylon.js +engine creation, the Playground's `NativeEngine` alias, and shader-helper script +loading live in `Scripts/dawn_playground.js`, explicitly loaded by the Playground +bootstrap, not in the plugin. + +On Windows, running only `lite_native.js`, `lite_parity_native.js`, or +`dawn_runtime_native.js` skips the +Babylon.js bootstrap entirely. The Lite test checks that no Babylon.js global or +pre-created Playground engine is present, then initializes its own WebGPU engine. + +For the full Lite parity catalog, clone Babylon-Lite under `build\lite-parity`, +install its locked dependencies using its declared Node/pnpm versions, and build +its library. Run `bundle-lite-parity.mjs` to produce a classic bundle for every +`scene-config.json` entry, then `prepare-lite-parity.mjs` to generate an isolated +copy of its Playwright tests: + +```powershell +node .github\scripts\bundle-lite-parity.mjs build\lite-parity \Scripts\lite-parity +node .github\scripts\prepare-lite-parity.mjs build\lite-parity \Playground.exe build\lite-parity-results 60000 +# Serve the Lite lab on 127.0.0.1:5179. From the Lite clone: +pnpm exec playwright test --config .native-parity\playwright.config.mjs +# From BabylonNative: +node .github\scripts\report-lite-parity.mjs +``` + +Use a new result directory for a post-fix run, and pass that directory to both +preparation and reporting. Preparation accepts an optional final generated-test +directory after the timeout; use a separate directory inside the Lite clone +when another suite is running, so its fixture and reference paths remain unchanged. +Concurrent native suites also require separate executable directories: the bridge +bootstrap configuration lives under each executable's `Scripts` directory. +Unset `RECAPTURE_GOLDEN` (the string `"false"` is +truthy in the upstream helper), unset `NATIVE_PARITY_BROWSER`, and set +`REUSE_BROWSER=0`. After rebuilding and before changing sources again, record +the executable and exact local-source fingerprints: + +```powershell +node .github\scripts\capture-dawn-provenance.mjs build\dawn build\lite-parity-postfix-results\provenance.json +``` + +The capture utility saves tracked patches and new-file contents beside the +provenance file under `source-patches`. Its optional final argument selects an +alternate executable when validating a separate build artifact. + +The reporter retains all attempts but summarizes the latest outcome per source +test location and full title path, including its project. Playwright gives +`--repeat-each` attempts different IDs; those attempts must not inflate distinct +case coverage. Metrics retain the actual attempt IDs and timestamps so failed +retry metrics do not contaminate the latest outcome. Oracle-only scene cases +and browser-only bundle-size/catalog checks are counted separately from native +cases. + +The native Page fixture transports evaluation and canvas readback over a +loopback-only bridge. Each native navigation gets a fresh Playground process; +Babylon.js reference navigations still use real Chrome. The adapter preserves +scene assertions and thresholds, rejects dimension mismatches, and attempts +quarantined scenes rather than omitting them. Unsupported native browser APIs +fail explicitly. Browser-only bundle-size checks are not native rendering +coverage. `Dawn-Lite-Parity.md` records each scene's outcome and evidence; a +timeout or unavailable oracle is not a pixel-parity pass. Generated tests, +copied references, logs, and images remain in the build directories. + +The default validation run compares rendered pixels against committed references. +`--generate-references` only checks scene loading/rendering and writes images; it +is not a pixel-regression check. Software-adapter output may differ from +hardware-generated references, so keep the Lite pixel comparison and runtime +regressions even when using reference-generation mode for the full CI smoke run. + ## **Building on Windows 10, Targeting Universal Windows Platform (UWP)** _Follow the steps from [All Development Platforms](#all-development-platforms) before proceeding._ diff --git a/CMakeLists.txt b/CMakeLists.txt index a111e264e4..b00c9e1fa8 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -41,6 +41,24 @@ FetchContent_Declare(CMakeExtensions GIT_REPOSITORY https://github.com/BabylonJS/CMakeExtensions.git GIT_TAG 631780e42886e5f12bfd1a5568c7395f1d657f43 EXCLUDE_FROM_ALL) +# Dawn (WebGPU) — only populated + built when BABYLON_NATIVE_PLUGIN_NATIVEDAWN is +# ON (see the guarded FetchContent_MakeAvailable below).

Shader Balls no longer crashes and passes at +full MAD **0.02472946**. Scene 283's bare `?live` query and original animation +checks pass after the shared URL repair. + +The rebuilt standalone native runtime passes **103 checks** and the Babylon.js +host passes **18 checks**. GUI Slate now passes its original Babylon.js WebGPU +pixel comparison with **no pixel difference**, after an actual initial +DynamicTexture upload breaks its resource-readiness cycle. The focused GUI +result is not a claim that the full Babylon.js catalog passes. + +### Subsequent framebuffer and gradient corrections + +The full run above uses executable SHA256 +`ff827b04f3854836e2a9727a1b4efb1f25cb02f42bd07f173516828fb299cde0`. +Later focused results are separate; they must not be attributed to that binary. +The latest isolated executable is +`build\dawn-frozen-frame\Playground.exe`, SHA256 +`05587d41e7bc019a296d9b9689460c4765ff89d36f46fb6f7c1e76cfc50377b0`. +Its runtime passes **106 checks**, host **20 checks**, and shared Canvas +**6 tests**. GUI Slate also passes its original zero-difference comparison on +the latest gradient build. + +Stopped render loops previously read an invalidated swapchain texture and +produced transparent black screenshots. TestUtils now preserves actual GPU pixels +before presentation and reads that texture after rendering stops, with explicit +invalidation on resize/reconfiguration. This is not a CPU-rendered substitute. +Scene 40 improves from MAD **106.0897081** to **0.3217773**, passing its original +ceiling. Scene 100 improves from **106.4898886** to **1.0142940** but still fails +its **0.5** ceiling; the remaining sphere-position difference is unresolved. +The copied scene-100 golden is byte-identical to the original. + +Chrome/native byte diagnostics reproduced systematic gradient-channel and +edge-alpha truncation. Shared linear/radial ramp packing now rounds components, +and the new GPU regression fails before the correction and passes afterwards. +Scene 51 now passes at MAD **0.09644676** against the unchanged **0.1** ceiling. +CSS HSL byte rounding improves scene 50 to **0.06555773**, but its original +**0.02** ceiling still fails. These results are preserved in +`build\lite-parity-frozen-frame-results` and +`build\lite-parity-gradient-results`, with source-patch archives and executable +identities. Two initial focused attempts hit a shared bridge-configuration +conflict; reruns use separate executable directories and do not claim those +initial attempts as renderer failures. + +All **31** original pixel-failing cases have also been rerun against the latest +isolated build: **10 now pass, 21 remain failures**, with no assertion, golden, +or ceiling changes. The passing cases are 40, 41, 42, 43, 44, 45, 46, 49, 51, +and 261. Their complete original assertions, not just readiness checks, passed. +The [latest pixel rerun report](build/lite-parity-latest-pixel-results/report.md) +records the remaining cases and fresh metrics. This focused improvement must not +be added to the older full-run total and presented as a new single-build survey. + +Scene 115's isolated golden changes because its original specification explicitly +requests `captureGolden(... force: true)`, not because a native image replaced +the reference. Its current native picking assertion remains a failure. + +Remaining representative failures include sprite-grid edges in 50, the +scene-100 physics position, and missing Worker support in 120. Device loss/recovery, pointer input, +multi-presentation-canvas behavior, DOM/CSS/media, and browser module-network +semantics remain separate capabilities; browser-only checks never count as +native passes. Scenes 102/103 have incompatible reference dimensions, and +shared browser failures are not established as NativeDawn defects. + +The dependency pins remain unchanged. The local UrlLib source is published as +[BabylonJS/UrlLib#39](https://github.com/BabylonJS/UrlLib/pull/39), at +`4dabd8dbd65d7406bf80d9c5b3f8d2108b0e17ef`. JsRuntimeHost is HEAD +`33e4a233dea178712352ec90a647683084bfbf1d` plus uncommitted source-patch SHA256 +`675da9a5ab3c5c465ffbe609f5dc9c49948dd2a55789bfcd1a3dcf4d57a4bc2c`. +That host's combined Windows checks pass on V8 (230) and QuickJS (221, with +eight V8-only clone skips); those are upstream host results, not native GPU +parity cases. Reproduction commands and local CMake overrides are in +[BUILDING.md](BUILDING.md), and exact source/executable/cache identity is in +[post-fix provenance](build/lite-parity-postfix-results/provenance.json). + +Representative screenshots are in +`build\lite-parity-corrected-results\references\\test-actual.png`, +alongside `babylon-ref-golden.png` and diff artifacts. Fresh all-catalog +screenshots use the same layout under `build\lite-parity-postfix-results`. + +### Completed full post-fix Lite survey + +The full original schedule now has **537/537 distinct cases completed**: +**464 passed, 68 failed, 5 timed out**, compared with the preserved baseline's +392 passed, 140 failed, 5 timed out. All **262 scenes were attempted natively**. +The native scene denominator is **201 passed / 272 cases**; three scene cases +ran only Chrome-oracle substeps, and 262 other checks are browser/Node extras +(260 pass). Those extras and oracle-only checks are not native rendering passes. + +Scene outcomes are **189 visual passes, 3 behavior passes, 31 pixel mismatches, +21 runtime failures, 8 timeouts, 5 harness limitations, 2 dimension mismatches, +and 3 other assertion failures**. No crashes or data-URL failures remain in this +survey. Ten runtime-failing cases require Worker; unsupported input/CSS/multiple +canvas behavior remains separate from renderer defects. + +The survey uses the earlier binary, before the subsequent framebuffer/HSL/gradient +corrections described above. It is therefore complete evidence for that build, +not a full-catalog verdict for the latest source. The two bridge-conflicted +original cases were repeated: scene 220 passes; scene 22 reaches its real +unsupported-CSS operation. Latest outcomes are deduplicated across 539 attempts +and retain all earlier records. + +The detailed per-scene report is +[full post-fix report](build/lite-parity-postfix-results/report.md); the original +baseline below remains unchanged. +The pending master merge is specifically `86975512f5945d8e3f6b2898dc2bfa4ed58051c8`; +`origin/master` advanced to `a6d4f731a4a1addbe5946b8ecbf82570c406dd8e` during +the work, and that newer revision is not part of the pending merge. + +### Completed Babylon.js WebGPU pixel catalog + +The original native Babylon.js catalog completed in **18m 46.156s**: +**714 executed, 708 passed, 6 failed, 0 missing references, 148 skipped** by its +unchanged configured exclusions. It used normal pixel-comparison mode, not +reference generation, and the earlier full-survey executable. Results, diff +images, the complete log, original provenance, and the tested executable are +preserved in `build\babylon-webgpu-postfix-results`. + +The final standard CMake build passes **106 runtime checks, 20 host checks, +6 shared Canvas tests, and 7 parity-tooling tests**. Its identity and archived +source patches are in `build\dawn-final-validation\provenance.json`. +All six original Babylon.js failures were rerun with that build and their +original pixel settings. **Iridescence NME passes in the isolated rerun**; +the five remaining failures are GUI Gradient Linear with transparency, +glTF Loader Cameras RH/LH, FrameGraph nrg gui bloom, and FrameGraph gui bloom. +That isolated result is not a newly completed 709/714 full run, nor proof the +Iridescence failure is permanently fixed. Fresh evidence is in +`build\babylon-webgpu-final-failures`. + +### Remaining integration work after upstream merges + +Merge and pin the shared JsRuntimeHost capabilities and the approved UrlLib +revision, then rebuild without local source overrides and repeat the runtime, +Lite, and Babylon.js checks. Only that consumer confirmation justifies deleting +old-pin URL/data-URL compatibility paths; local-source results alone do not. +JsRuntimeHost's current patch remains uncommitted, and this work does not change +either dependency pin. + +Merge the canonical Babylon.js headless font-line-box correction and refresh +that consumer only when authorized. The isolated 9.21.2 backport confirms the +source fix; it is not a reason to keep a runtime engine override in NativeDawn. +Repeat the complete catalog after installing the published upstream revisions. + +Complete real device-loss/recovery, asynchronous Dawn callback scheduling and +resource ownership, per-device/per-canvas state, and ImageBitmap conversion +options/lifetime. Worker, input, DOM/CSS/media and module-network behavior require +real host implementations, not successful no-ops in NativeDawn. Resolve the +remaining pixel/picking differences against their original oracles, and keep +shared browser/reference failures separate. Canvas zero/large dimensions, +no-context serialization, font metrics, and cross-platform/engine validation +also remain incomplete. + +### Transparent gradients and real font measurement + +The subsequent standard build passes **111 standalone runtime checks**, including +transparent linear/radial ramps, actual proportional fallback-font advances, +ink/font extents, and font save/restore. The duplicated Dawn measurement helper +and synthetic per-character Arial widths are removed; both renderers use the +shared Canvas metrics implementation. + +Chrome's actual `#ff0000ff` to `#00000000` ramp disproved the previous +premultiplied-stop assumption: midpoint straight RGB and alpha both decrease. +The shared gradient correction now interpolates straight RGBA stops. The original +**GUI Gradient Linear with transparency has zero divergent pixels**. Both +original glTF camera tests also pass, at **5046/240000 pixels (2.103%)**, below +their unchanged **2.5%** allowance. The five-failure replay is **3 passed / +5 executed**, separate from the earlier complete 714-test run. + +Broader original GUI coverage executes **14 tests, 11 pass, 3 fail, 9 configured +skips**. The two GUI bloom cases remain failures, and accurate glyph/layout +measurement exposes a GUI Force Resize Width mismatch that previously passed. +These remaining images implicate text layout, not the otherwise-matching 3D +geometry. A controlled, temporary **Babylon.js line-box-first font-offset +diagnostic passes all 14 eligible GUI cases**: Force Resize differs at 1.682%, +and bloom at 2.340%/2.335%, under the original allowances. The default runner and +bundle were restored afterwards; those diagnostic passes are not canonical +upstream/default-package results. A dedicated Babylon.js session owns the +reusable source correction and regressions. + +Evidence, original and diagnostic logs, font identities, source archives and +the new executable identity are in `build\dawn-canvas-correctness-results`. +The original full surveys and their earlier targeted results remain unchanged. + +### Canonical font-line-box consumer confirmation + +The reusable Babylon.js correction now prefers a complete, finite font-bounds +pair with positive total height before falling back to a complete ink-bounds +pair and the existing CSS-size estimate. DOM layout remains the preferred path. +Its upstream source passes **27 focused tests**, core type checking, and +changed-file lint/format checks. The Babylon.js work remains uncommitted. + +The source-generated backport changes only the font-offset fallback in the +exact **9.21.2** consumer bundle; all other bytes and Engine.Version remain +unchanged. It is packaged separately in `build\dawn-font-linebox`, not installed +into the default package or dependency pins. The native executable SHA256 is +`90af372a652e8f64bf1978ed3bb642021e8bfd3c27252866b4ed5ceac971d792`; +the canonical consumer bundle SHA256 is +`4f8a3a9ac2ca2b51fe444ac1be118ba0bc5cd39c61c11408a74d1d18b82d9018`. + +The first canonical GUI sequence recorded **13 passes / 14 executed**: GUI +Slate failed readiness convergence, not pixel comparison. Without changing +the source, render budgets, references, thresholds, or exclusions, Slate then +passed **three isolated attempts with zero divergent pixels**, and the full +GUI sequence passed **14/14**, with nine configured skips. Force Resize differs +at **1.682%**, and the two bloom cases at **2.263% / 2.259%**, below their +original **2.5%** allowances. Camera RH/LH and Iridescence also pass **3/3**. +The initial readiness failure remains archived; these repeats do not establish +that its intermittent cause is fixed. + +Consumer logs, the exact upstream patch, regeneration script, and provenance +are preserved in `build\babylon-webgpu-font-linebox-results`. The separate +complete original Babylon.js WebGPU pixel catalog now passes **714/714**, +with **zero failures, zero missing references, 148 unchanged configured skips, +and exit 0**, in **12m 37.242s**. This is an actual complete run using the +canonical consumer and local shared-source overrides, not an extrapolation +from the targeted passes or a verdict for the default pinned bundle. The tested +executable, consumer bundle, runner/catalog hashes, complete log and summary +are archived in `build\babylon-webgpu-canonical-results`. + +The newest standard-build Lite pixel subset initially recorded **9 passes / +31 executed**, with scene 40 failing at MAD **0.6159060** against **0.5**. +Three exact-selector repetitions of its unchanged original specification all +pass at approximately **0.3217773**. Its reference is captured live by Chrome +on each attempt; the earlier discrepancy's cause remains unresolved. Latest +outcomes are **10 passed / 31 distinct cases across 34 attempts**, not 33 +distinct cases: Playwright's repeat-specific IDs represent attempts of the +same source test. The first subset outcome and the three repeats remain +separate evidence in `build\lite-parity-canvas-results`; neither updates the +older 537-case full-survey total. + +## Preserved baseline + +**Run status: failed.** Generated 2026-10-06T09:56:57.911Z. + +Babylon-Lite `206de862a935c4ceace9aaf0107062f1effbd5fa`; BabylonNative `cbb2f4eee370e33694f8f7dc294410d7b37fbbdc` plus the uncommitted merge of master `86975512f5945d8e3f6b2898dc2bfa4ed58051c8` and this test adapter.

The generated suite preserves original assertions, queries, readiness flags, interactions and comparison ceilings; four demos without specs get execution-only attempts. Real Chrome runs Babylon.js oracle substeps. No native-generated image is used as a Babylon.js reference. Copied goldens and fresh captures stay in the build artifacts, not the Lite checkout. MAD is mean absolute RGB byte error (0-255), not a percentage. Region and behavioral assertions remain enforced by the original specs, even though the table shows only the largest full-image MAD. + +PASS requires all completed scene cases to pass and a recorded native navigation. BEHAVIOR PASS has no Babylon.js pixel oracle. TIMEOUT is inconclusive at the recorded deadline, not proof of an unsupported renderer feature. Oracle/build/adapter failures are explicitly distinguished from native failures. Browser-Lite diagnostic replays use the same assertions rather than an approximate screenshot. + +Generated-only adaptations: corrected upstream repository/reference paths, loopback native Page transport, independent scene processes, quarantines attempted instead of skipped, serial groups without fail-fast sibling skips, test deadlines capped at 60 seconds, and strict dimension equality before image comparisons. IIFE execution does not provide browser module-chunk network semantics. Unsupported DOM/input/media/control operations fail explicitly; they are not replaced with successful no-ops. + +## Results + +The primary suite completed **537 cases**: **392 passed**, **140 failed**, **5 timed out**.

Supplemental 180-second readiness attempts and URL-tagged fetch retries add evidence without turning an unverified image into a parity pass.

Inline data:image fetch rejection is a native polyfill capability gap, not a network outage. The two native crashes in scenes 12 and 304 have callstacks in UrlLib's Windows HTTP ContentType handling, not a proven GPU shader crash. Scenes 102/103 have 1359x765 committed goldens against a 1280x720 run; their dimension mismatches are invalid comparisons, not visual failures. + +Scene 164 captured its pre-loss frame but never observed `dataset.deviceLost`; recovery cannot be claimed.

Separate, +observational native runs identified decoder-loading, device-lifecycle and +missing HTML-control failures.

Scene 112 receives the +glTF, binary and every requested KTX2 body by 0.553s, but the decoder script +appended at 0.197s never installs `KTX2DECODER`. Scene 211 receives its glTF +and binary by 0.082s, then appends `meshopt_decoder.js` at 0.083s without +installing `MeshoptDecoder`. Scene 315 receives its complete 4,890,384-byte +coastal-cliff GLB at 0.583s and appends `/draco_decoder.js` at 0.585s; +its environment and BRDF bodies also completed successfully. It is blocked +before task registration/rendering, not in the final 15-frame settling loop. +All five still have zero scheduled/completed animation-frame callbacks and +undefined corresponding decoder globals at their diagnostic deadlines. + +This matches the actual loader implementations: each awaits a dynamically +appended script's `onload`/`onerror`, but NativeDawn's document-head +`appendChild` is a no-op. The initialized native runtime does not execute those +scripts, so neither callback settles the loader promise. Increasing the timeout +does not provide the missing loading behavior. The fix belongs in explicit, +host-independent decoder initialization or the shared host's real script-loading +capability, not a decoder-specific NativeDawn global injection. Decoder/WASM +execution, decoded content and pixel output still need verification after that +first gate is implemented; these observations do not prove the later stages work. + +**Device recovery, scene 164:** the diagnostic run loads the scene, freezes the +animation, saves a real pre-loss screenshot and sets `captured=true`. +`GPUDevice.destroy()` is actually called at 2.591s, but `device.lost` never +resolves and no `deviceLost`, `deviceRecovered` or replacement-resource flags +appear. The old scene continues rendering, reaching 1,796 frames by the +33.332s observation endpoint. This is an implementation gap, not a stalled RAF +or shader: NativeDawn currently implements `destroy()` as a no-op and creates +a `lost` promise with no resolving path. Genuine device ownership, destruction, +loss notification and replacement/recovery need implementation. No post-loss +image invariance or resource reconstruction is established. The diagnostic +[pre-loss screenshot](build/urllib-validation-20261007/readiness/scene164-before-loss.png) +is retained separately from the original full-run screenshot. + +**Text demos, scenes 180/181:** both successfully load all 876,576 bytes of +`Inter.ttf` with HTTP 200, then reject with +`TypeError: Cannot read properties of null (reading 'value')`. +The missing element is `textInput`; scene 180's sliders and labels are also +absent. The native bridge evaluates the scene bundle without materializing +these pages' HTML controls. Their terminal `void run()` discards the rejected +promise, so the original records show a deadline rather than the underlying +stack. Adding rejection reporting only to separate diagnostic bundle copies +exposes the error within approximately 1.4s. This needs an honest host/adapter +UI capability or a supported explicit non-DOM text entry point, not a longer +font timeout or dummy controls reported as parity. Text rendering itself was +not reached. + +Evidence, including per-second datasets, completed body transfers, script +appends, device lifecycle observations and the terminal stacks: +[Lite readiness diagnostics](build/urllib-validation-20261007/readiness/lite-readiness.json), +[diagnostic bundle identities](build/urllib-validation-20261007/readiness/bundle-identities.json), +[driver](build/urllib-validation-20261007/readiness/probe-lite.mjs), +[telemetry](build/urllib-validation-20261007/readiness/telemetry.js). +Only diagnostic copies of scenes 180/181 add terminal rejection reporting; +the other six diagnostic scene bundles are byte-identical to the tested +originals. The bridge temporarily copies these into its runnable consumer; +the two modified text bundles were restored afterward. All **1,674 recorded +files across the three original consumers** match their pre-run hashes. +Scene sources, executable, references and assertions remain unchanged. + +## Babylon.js WebGPU visualization + +The unchanged 9.21.2 consumer records these five failures: + +| Test | Failure | Divergent pixels / original allowance | +|---|---|---| +| GUI Near Menu | Did not converge within 240 render-loop ticks | No completed pixel comparison | +| GUI Force Resize Width | Pixel mismatch | 8044/240000, 3.352% / 2.5% | +| FrameGraph nrg gui bloom | Pixel mismatch | 6120/240000, 2.550% / 2.5% | +| FrameGraph gui bloom | Pixel mismatch | 6104/240000, 2.543% / 2.5% | +| Iridescence NME | Pixel mismatch | 29506/240000, 12.294% / 2.5% | + +The separately packaged canonical font-line-box backport then passes the +complete **714/714** catalog. It changes only the canvas font-offset fallback +in the exact 9.21.2 bundle; it does not replace the whole package, change +Engine.Version, or install a runtime plugin workaround. + +Both full runs use the same executable, fixed UrlLib, JsRuntimeHost source, +runner, catalog, references, and comparison settings. The runner SHA256 is +`cc74003f969793d87464b3d2b8651a0648d7f31356bcd7e0c7009ec71afb3214`; +the catalog SHA256 is +`2887256e1d6404219ca7248fb7020cda5181bbfa3a3e5011eac1a02ce5f48500`. +The canonical consumer is a labelled local integration experiment, not a +verdict for the unchanged default dependency pins. + +The font correction addresses the known headless GUI line-layout issue. +Sequential asset/loading timing also differs between runs: the passing +canonical Near Menu and Iridescence results do **not** prove that font metrics +fixed those intermittent failures. These runs are likewise not a controlled +UrlLib-only comparison; existing NativeDawn and shared-host fixes are included. + +Logs, summaries, native result/diff images, and tested packages: +[unchanged-bundle summary](build/urllib-validation-20261007/standard/summary.json), +[unchanged-bundle log](build/urllib-validation-20261007/standard/validation.log), +[canonical summary](build/urllib-validation-20261007/canonical/summary.json), +[canonical log](build/urllib-validation-20261007/canonical/validation.log). +The canonical directory also contains the upstream patch, regeneration script, +and bundle provenance. + +### GUI Near Menu: intermittent convergence, not a pixel failure + +The original failure is the **240 render-loop-tick convergence guard**, not the +separate **600s initial resource-readiness deadline**. The guard checks the main +scene and associated utility scenes for `scene.isReady()`, GUI texture readiness, +dirty material defines and unfinished effects. On a blocked tick, it increments +scene render IDs but does not render the scene or advance the test's frame index. +Consequently the original failed attempt never reaches its 60 comparison frames +or saves a rendered screenshot. Repeated error text in the log is banner/log +mirroring, not three independent attempts. + +Three fresh isolated repetitions with the unchanged 9.21.2 bundle and original +runner produced **one convergence failure (8.244s), then two passes (2.499s and +2.439s)**. Both successful pixel comparisons measured **552/240000 = 0.230%**, +well below the unchanged 2.5% allowance. The passing screenshot is preserved +[separately](build/urllib-validation-20261007/readiness/gui-near-menu-original-attempts-2-3.png); +it is not evidence that the original full-catalog failed attempt captured a frame. + +An additional five isolated repetitions used a separately named, reason-only +diagnostic runner. It retains the original 240-tick/600s limits, frame progression, +consumer bundle and comparison settings. **All five passed**, each at the same +0.230% pixel difference; none entered a blocked convergence guard. Therefore the +exact blocking predicate/object of the intermittent failure is **not yet +identified**. Later quick passes are consistent with loading/compilation timing, +but no cold-cache or controlled-network experiment was performed, so cache +warm-up is not a proven cause. The scene constructs a GUI3DManager, NearMenu and +three TouchHolographicButtons; no evidence ties its failure to UrlLib's POST fix +or proves the font backport resolves it. + +The original fresh full-catalog verdict remains failed. The next meaningful +investigation is to reproduce that failure with the guard diagnostics enabled, +not simply raise the deadline or count retries as a pass. No RenderDoc capture +was attempted because the failing attempt never reached pixel comparison. +Evidence: +[original failed isolated run](build/urllib-validation-20261007/readiness/gui-near-menu-original-1.log), +[original passing run](build/urllib-validation-20261007/readiness/gui-near-menu-original-2.log), +[instrumented run](build/urllib-validation-20261007/readiness/gui-near-menu-diagnostic-1.log), +[diagnostic runner generator](build/urllib-validation-20261007/readiness/prepare-gui-probe.mjs), +[derived runner](build/urllib-validation-20261007/readiness/gui-derived-runner.js), +[runner hashes](build/urllib-validation-20261007/readiness/gui-runner-provenance.json). +All three original and five instrumented logs are in the same `readiness` directory. +The temporary GUI runner was removed from the original consumer afterward; +the generator recreates it for a labelled diagnostic repetition. + +### Iridescence NME: reproduced material-assignment readiness race + +The exact scene is [#2FDQT5#1507](https://playground.babylonjs.com/#2FDQT5#1507). +Its failed image contains a **black sphere**, not a subtly incorrect iridescence +color. The reference and canonical passing frame show the environment-reflecting +iridescent sphere. At `(300,200)`, the failed RGBA is `(0,0,0,255)` versus +`(94,98,57,255)` in both the reference and passing frame. + +The scene returns synchronously while this asynchronous work is outstanding: +`NodeMaterial.ParseFromSnippetAsync("Q9NP6V#0", scene).then(...)` assigns +`sphere.material` only when the promise finishes. The catalog has no +`renderCount`, so comparison occurs on **frame 1**. Scene/material readiness +can succeed while the sphere still has no explicitly assigned material; the +runner cannot infer that an unawaited application promise will replace it. +The scene creates no lights, so that temporary default-material sphere is black. + +Separate native runs used an isolated copy of the unchanged 9.21.2 consumer, +with identical executable, catalog, reference, first comparison frame, +600s/240-tick readiness limits, channel threshold 25 and 2.5% allowance: + +| Experiment | Attempts | Result | Divergent pixels | +|---|---:|---|---:| +| Original scene and original runner | 3 | 3 passed | 600/240000, 0.250% | +| Original scene, material-timing observations only | 3 | 3 passed; NodeMaterial assigned before capture | 600/240000, 0.250% | +| Original scene, real material-promise fulfillment held for 2s | 3 | 3 failed; material still null at frame-1 capture | 29506/240000, 12.294% | +| Await assignment before returning, preserve setup order, same 2s delay | 3 | 3 passed; NodeMaterial assigned at capture | 600/240000, 0.250% | +| Same order-preserving await, without added delay | 3 | 3 passed | 600/240000, 0.250% | +| Initial inline-await controls that moved skybox setup after material construction | 2 | 2 failed; ordering-confounded controls, not the proposed fix | 29506/240000, 12.294% | + +**All three delayed/unawaited frames are RGBA pixel-for-pixel identical to the +original full-catalog failure.** At their capture times (0.505s, 0.670s and +0.520s from runner start), diagnostics show `materialAssigned=false`, +`resolved=0`, `pendingResources=0` and `compareFrame=1`. The delay holds the +actual successful parser's promise delivery; it does not substitute a fake +material, alter the network response, or increase the rendering frame count. +These controlled runs establish a reproducible application-readiness failure +mechanism matching the original image. The original full-catalog log did not +record material state or request latency, so its exact late-request timing +cannot be reconstructed. + +**Every passing frame, including the unchanged 9.21.2 repetitions, is RGBA +pixel-for-pixel identical to the earlier canonical consumer's passing frame.** +The original 29,506 divergent pixels consist of 28,906 sphere-region pixels +within `x=204..395, y=103..296`, plus 600 pixels on the final image row. +The passing frames retain only those 600 final-row differences (0.250%, below +the original allowance). This investigation did not diagnose or modify that +separate last-row discrepancy. It found no persistent iridescence-color +difference once the real material was installed, and provides no reason to +attribute this failure to the font-metrics correction. + +The appropriate correction is **in the playground scene's initialization +contract**, not a NativeDawn shader change, a timeout increase, a larger +`renderCount`, or a renderer-wide node-material interception. Make its existing +`createScene` asynchronous and await the actual material-assignment promise +**after the original skybox/environment setup and before returning the scene**: + +```javascript +const materialReady = BABYLON.NodeMaterial.ParseFromSnippetAsync("Q9NP6V#0", scene) + .then(nodeMaterial => { sphere.material = nodeMaterial; }); +scene.createDefaultSkybox(environmentTexture, true, undefined, 0.3, true); +await materialReady; +return scene; +``` + +Setup order matters: simply adding an inline `await` before +`createDefaultSkybox` moved environment setup until after node-material +construction and also produced black frames despite an assigned NodeMaterial. +The graph's `ReflectionBlock` falls back to `scene.environmentTexture`. +Those two unsuccessful controls are retained, rather than omitted or counted +as validation of the correction. The order-preserving experiment changes only +when the scene is returned; all original setup remains in its original order. + +No production scene/catalog, NativeDawn implementation, default bundle, +dependency pin, reference or threshold was changed for this investigation. +The proposed scene correction was exercised only in separately labelled +diagnostic runners. The original full-catalog failure remains recorded as failed. +No RenderDoc capture was needed to identify this readiness mechanism. + +Evidence: +[structured image/timing analysis](build/urllib-validation-20261007/iridescence/analysis.json), +[delayed original-scene log](build/urllib-validation-20261007/iridescence/delayed-unawaited-1.log), +[delayed black-sphere reproduction](build/urllib-validation-20261007/iridescence/delayed-unawaited-1.png), +[order-preserving delayed log](build/urllib-validation-20261007/iridescence/delayed-awaited-preserving-order-1.log), +[order-preserving passing frame](build/urllib-validation-20261007/iridescence/delayed-awaited-preserving-order-1.png), +[unchanged isolated log](build/urllib-validation-20261007/iridescence/original-1.log), +[runner generator](build/urllib-validation-20261007/iridescence/prepare-probe.mjs), +[runner provenance](build/urllib-validation-20261007/iridescence/runner-provenance.json), +[initial-control source provenance](build/urllib-validation-20261007/iridescence/first-runner-provenance.json), +[copied-consumer identities](build/urllib-validation-20261007/iridescence/consumer-identities.json). +All 17 logs, frames, original/corrected diagnostic runner sources, and public +scene/node-material JSON payloads are retained under +`build\urllib-validation-20261007\iridescence`. + +## Reproduction and integrity + +The retained runnable consumers are under +`build\urllib-validation-20261007\standard\consumer`, +`build\urllib-validation-20261007\canonical\consumer`, and +`build\urllib-validation-20261007\lite\consumer`. +From either Babylon.js consumer directory: + +```powershell +.\Playground.exe --headless app:///Scripts/validation_native.js +``` + +For Lite, start the lab in one terminal: + +```powershell +Set-Location build\lite-parity\lab +npx --offline --package node@22.22.0 --package pnpm@11.23.0 -- pnpm exec vite --host 127.0.0.1 --port 5179 --strictPort +``` + +From the repository root in another terminal: + +```powershell +Remove-Item Env:NATIVE_PARITY_BROWSER,Env:NATIVE_PARITY_REPORT,Env:RECAPTURE_GOLDEN,Env:CI -ErrorAction SilentlyContinue +$env:REUSE_BROWSER = '0' +Set-Location build\lite-parity +npx --offline --package node@22.22.0 --package pnpm@11.23.0 -- pnpm exec playwright test --config .native-parity-urllib-20261007\playwright.config.mjs +``` + +Use a new artifact directory when preparing another independent run so these +logs and first-attempt outcomes remain preserved.

Of 262 non-scene checks, 260 pass; the two failures are explicitly +unsupported adapter routes for `demo-ocean.html` and `/`, not demonstrated +renderer failures. + +Scene verdicts are 170 PASS, one BEHAVIOR PASS, four HARNESS LIMIT, 13 PIXEL +MISMATCH, three CRASH, seven FAIL, nine TIMEOUT, 22 ASSET / FETCH FAIL, +31 RUNTIME FAIL and two DIMENSION MISMATCH. These scene classifications are +not the same denominator as the six Playwright timed-out cases. +The three crashes (scenes 12, 186 and 304) retain native stacks in +`HttpMediaTypeHeaderValue::ToString` / `UrlLib::UrlRequest::Impl::LoadHttpAsync`, +matching the absent-response-MIME defect excluded from this pinned consumer. +Readiness/deadline failures remain visible rather than being converted to +synthetic successful frames. + +### Integration corrections and remaining blockers + +The first build exposed duplicate Windows output rules for the byte-identical +`DroidSans.ttf` and Dawn-only `droidsans.ttf`. Removed redundant Dawn packaging +and use the common upstream asset, with canonical URL capitalization. No +font bytes or reference images were substituted. Provenance capture now +resolves fetched dependency sources when no override is configured. + +The initial full run also exposed a merge-introduced input regression: +upstream BGFX's `getRenderingCanvas() => window` / +`getInputElement() => 0` overrides had replaced Dawn's real canvas methods. +Restricting those overrides to non-Dawn engines fixes the +`getBoundingClientRect` TypeError. **Picking Visual Test passes** in a focused +native run and the second complete catalog run. First-run evidence is retained. +Lite does not load `validation_native.js`, so that visualization-only guard +does not invalidate or require repeating its completed run. + +The large new visualization failure cluster includes explicit Cube/2D shader +binding-dimension errors, invalid render pipelines and invalid command buffers. +A diagnostic-only observer forwards device descriptors unchanged and records +the actual WGSL, layouts and pipelines. It found invalid JavaScript +`texture.viewDimension` values containing `{groupIndex, bindingIndex}` rather +than WebGPU dimension strings, **before NativeDawn translates the descriptors**. + +An isolated, GPU/network-free reproduction localizes a concrete packaging +defect to the upstream ES5 downlevel step: TypeScript 5.9.3 emits the same +`_40` name for the WGSL processor's dimension value and its destructuring +temporary. The later assignment overwrites the dimension before +`_addTextureBindingDescription` is called. The authoritative 9.29.0 source +returns `"2d"`, `"cube"` and `"2d"` for the three tested texture kinds; the +tested packaged copy returns binding-coordinate objects for all three. +Full-program emission and a diagnostic TypeScript 6.0.3 emission also retain +the collision, so neither was adopted as a fix. The original package and +reproducible extraction test are retained separately; tested consumers were +not modified. + +This is a proven pre-GPU descriptor-construction fault, **not proof that every +one of the 249 pixel failures has that sole cause**. The canonical downlevel +pipeline needs correction while preserving legacy-engine support; inferring +dimensions or rewriting shaders in NativeDawn would conceal the defect. +NativeDawn's existing non-string enum defaulting also masks this invalid input +and needs proper API validation separately. No speculative renderer workaround, +bundle swap, threshold relaxation or new exclusion was applied. The historical +9.21.2 Iridescence material-readiness diagnosis is not evidence that its new +9.29.0 failure has the same cause. + +### Retained evidence and reproducibility + +Artifact root: + +```text +C:\Users\cedric\dev\copilot-worktrees\BabylonNative\cedricguillemet-supreme-waffle\build\master-validation-20261007 +``` + +- [Corrected full summary](build/master-validation-20261007/run-summary-corrected.json), + [initial full summary](build/master-validation-20261007/run-summary.json) and + [complete Lite scene report](build/master-validation-20261007/lite/report.md). +- [Corrected visualization log](build/master-validation-20261007/standard-corrected/validation.log), + [Lite full-suite log](build/master-validation-20261007/lite/full-suite.log) and + [focused input result](build/master-validation-20261007/standard-corrected/picking-smoke.log). +- [Recorded binding descriptors](build/master-validation-20261007/binding-probe/probe.log), + [descriptor analysis](build/master-validation-20261007/binding-probe/analysis.json), + [isolated emitter reproduction](build/master-validation-20261007/binding-probe/emitter-reproduction.json) + and [reproduction script](build/master-validation-20261007/binding-probe/reproduce-downlevel-collision.mjs). +- [Corrected provenance](build/master-validation-20261007/standard-corrected/provenance.json) + and [Lite provenance](build/master-validation-20261007/lite/provenance.json). + +Final visualization result PNGs and red diff overlays are respectively in +`standard-corrected\consumer\Apps\Playground\Results` and +`standard-corrected\consumer\Apps\Playground\Errors` under that root. +There are 704 result files and 242 diff files; multiple catalog tests share +reference-image filenames, so these are not 727 and 249 unique screenshots. +The complete log identifies every failed title.
