# v24.1.3 completion audit
|
||||
|
||||
## 判定
|
||||
|
||||
**v24.1.2で実ブラウザからWGSL reserved-word parse errorが報告されたため、従来のrelease判定を撤回。v24.1.3でshader命名とfallback負荷を修正し、静的・CPU数値モデル・build gateを再実行してPASS。実WebGPU adapter acceptanceはこの環境では引き続き未実行。**
|
||||
|
||||
実GPU未実行を「PASS」とは扱いません。
|
||||
|
||||
## 修正済みの重大事項
|
||||
|
||||
1. f32量子化BLAによるmembership反転
|
||||
- production BLAを完全除去。
|
||||
2. BLAなしperturbationのfalse bounded反例
|
||||
- roundoff error boundを導入し、既知反例を`UNKNOWN`へ退避。
|
||||
3. recolor/render token race
|
||||
- `recolorPending`方式へ変更。
|
||||
4. redundant Strict retry
|
||||
- 1-pass policyへ整理し、大画面queue/indirect dispatchを削除。
|
||||
5. Exportの4 readback/tile
|
||||
- 4 sampleを1 command streamで処理しGPU resolve後1 readback。
|
||||
6. Exportのtile resource churn
|
||||
- 512² reusable GPU workspaceへ変更。
|
||||
7. 16K巨大Canvas
|
||||
- streaming PNGへ変更。
|
||||
8. deep JS fallback誤描画
|
||||
- deep fallbackを明示拒否。
|
||||
9. WGSL parse error (`meta` / `smooth` reserved words)
|
||||
- storage変数を`fieldMeta` / `fieldSmooth`へ改名。WGSL予約語を全shaderで走査する回帰テストを追加。
|
||||
10. WebGPU shader/pipeline failure時のCPU暴走
|
||||
- shader/pipelineエラーではJavaScript full-frame fallbackを起動せず停止。WebGPU自体がない場合だけ軽量fallbackを使用。
|
||||
11. 画面描画負荷
|
||||
- standard screen budgetをdesktop約4M→1.5M、小型端末約2M→0.75Mへ低減。power約0.5M、fine最大約3M、Strict最大約2M。
|
||||
12. WebGPU canvas context claim
|
||||
- pipeline成功後へ遅延。
|
||||
13. e340以深の座標表示0化
|
||||
- fixed-point exact decimal formatterの340桁capを撤去。
|
||||
|
||||
## CPU numeric regression
|
||||
|
||||
`guarded-production-equation-cpu-f32-model-not-real-gpu`:
|
||||
|
||||
- period2-cusp-z14: false escaped 0 / false bounded 0 / UNKNOWN 0
|
||||
- period2-cusp-z20: 0 / 0 / 0
|
||||
- period2-cusp-z100: 0 / 0 / 0
|
||||
- period3-interior: 0 / 0 / 0
|
||||
- period2-cusp-e280: 0 / 0 / 0
|
||||
- period2-cusp-e400: 0 / 0 / 0
|
||||
- swirly-seahorses-z12: false escaped 0 / false bounded 0 / UNKNOWN 71 of 187
|
||||
|
||||
BalancedとStrictの両方で上記membership gateを満たします。swirlyの未確定率は既知の制約で、誤分類より保守退避を優先しています。
|
||||
|
||||
Shallow f32 modelは693 sampleでfalse escaped 0 / false bounded 0。escape iteration count差は2 sampleあり、membership certificationを名乗らない理由の一つです。
|
||||
|
||||
## BLA status
|
||||
|
||||
production sourceにBLA builder/evaluator/node/levelはありません。再導入にはf32係数量子化を含む誤差上界付き受入条件が必要です。
|
||||
|
||||
## Export audit
|
||||
|
||||
- tile max 512²
|
||||
- reusable GPU workspace
|
||||
- 2×2 AA: one readback/tile
|
||||
- unresolved counterをRGBA readback末尾へ同梱
|
||||
- PNG signature / IHDR / CRC / multiple IDAT / inflate scanlineをNode modelで検証
|
||||
- abort path settles without unhandled rejection
|
||||
|
||||
## Real WebGPU acceptance
|
||||
|
||||
`tests/webgpu-acceptance.html`は以下を実adapterで検証します。
|
||||
|
||||
- shader compilation
|
||||
- standard / Strict deep dispatch
|
||||
- BigInt reference guard
|
||||
- sampled membership
|
||||
- dense known regressions
|
||||
- Export 1× / 2×2 readback
|
||||
- uncaptured validation errors
|
||||
|
||||
stable scenesはsampled UNKNOWNを許容しません。swirlyは25 sample中12以上の確定を要求します。
|
||||
|
||||
この作業環境のChromiumは`navigator.gpu`を公開しないため、このgateは未実行です。`audit/v24-real-webgpu-status.json`に環境結果を記録します。
|
||||
|
||||
## v24.1.3 hotfix verification
|
||||
|
||||
- WGSL 16.2 reserved-word scan: PASS (5 shader modules)
|
||||
- `meta` / `smooth` WGSL identifier occurrences: 0
|
||||
- source contract: PASS (28 checks)
|
||||
- `npm test`: PASS
|
||||
- clean `npm run build`: PASS
|
||||
- source ↔ standalone/hosted hashes: identical
|
||||
- shader/pipeline init failure: CPU full-frame fallback is not entered and failed init is not retried every render
|
||||
- normal desktop screen budget: ~1.5M px (v24.1.2 ~4M px)
|
||||
- no-WebGPU/no-adapter fallback budget: ~0.25M px
|
||||
|
||||
実WebGPU adapter上のv24.1.3 compile/dispatchだけは、このコンテナではadapterを得られないため未実行です。v24.1.2で報告されたreserved-word parse failureそのものは、仕様予約語の除去とreserved-token回帰gateによってsource上修正済みです。

ただし、固定実機を必要とするbrowser acceptanceは実行環境にin-app Browserが存在しないため未実施である。性能修正後に再開した接続監査でも3回連続のgoal turnで利用可能Browser 0件となり、2026-08-22T10:48:56.1197927Zに外部状態待ちのblockerとして再確定した。Node固定sceneではdeep BLAの高いMPPを確認し、標準deepを約1.4秒の実測時間予算へ変更済みだが、これはCanvas、Worker、入力、downloadを含むbrowser gateの代替ではない。またPhase 3BとPhase 4は、提案書自身がbrowser telemetryで支配コストまたは誤差を確認した場合だけ実施すると定義した条件付き項目であり、trigger判定も未実施である。したがって本監査は「実装・非ブラウザgate合格、実機受入blocked」と判定する。

重要な契約は次の通り。
|
||||
|
||||
- Previewは粗くてよいが、新しい未解決画素を「内部」と断定して黒にしない。
|
||||
- Coveredはズーム深度に関係なく、確定したScreen Canvas gridを新しいViewSpecの実sampleだけで全域計算する。再投影した旧frameは描画中のpresentationにだけ使い、coverageへ数えない。
|
||||
- 標準モードは明示したeffective DPR、精細モードは原則native DPR、Exportは指定gridをtargetにする。DPRを画素予算で下げた場合は実解像度を表示する。

||||
- Coveredはズーム深度に関係なく、確定したScreen Canvas gridを新しいViewSpecの実sampleだけで全域計算する。再投影した旧frameは描画中のpresentationにだけ使い、sample coverageへ数えない。計算済み`UNRESOLVED`はsample coverageへ数えるがresolved coverageへは数えない。
|
||||
- native DPRは上限であり、標準・精細とも明示したpixel/memory budget内で使う。精細は時間適応で解像度を下げないが、memory/pixel上限は維持する。DPRを制限した場合はeffective DPRと実解像度を表示する。
|
||||
- Refinedは単なる2倍補間ではなく、複数の実サンプルをlinear-lightでresolveする。
|
||||
- Validatedは数学的なマンデルブロ集合所属証明ではなく、宣言した有限反復・precision policyの照合完了を表す。全sampleへ誤差境界または証明手続きを適用する将来モードだけを`Certified`と呼ぶ。
|
||||
- 「高精細」と「数値検証完了」を同じチェックボックスにしない。
|
||||
- Exportは表示Canvasとは独立したjobであり、view、寸法、反復方針、AA、乱数seedを固定してから開始する。

## 10. 実装ロードマップ
|
||||
|
||||
### Phase 0 — v22基準化
|
||||
P0/P1/P2は利用者影響のseverityであり、実装順ではない。各項目はphase、依存先、mandatory / telemetry-conditional、未通過gateを追跡する。後段実装を先行できても、前段gateを通過したとは扱わない。
|
||||
|
||||
### Phase 0A — browser非依存の証拠基準化
|
||||
|
||||
- shallow/deep/colorを含む全kernel sourceを回収または復元し、固定toolchain、compile flags、生成script、payload checksumを揃える。
|
||||
- z0 / z14 / z20 / z100 / period-3 interior / boundary / 10^-280付近を固定sceneにする。
|
||||
- z0 / z14 / z20 / z100 / period-3 interior / boundary / 10^-280付近をversion付き固定sceneにする。中心座標はspan相応のguard digitsを持つdecimalかexact rationalとし、precision kind、oracle、期待分類、iteration policyをscene schemaへ保存する。
|
||||
- v22成果物が残っている場合は全対象hashとbaselineをimmutableに保存する。残っていない場合は「v22比較不能」と機械可読に記録し、後からv23値で代用しない。
|
||||
- 現行`exactDeepPixel`とは独立した、複数精度一致と誤差上限を持つ高精度reference実装で、分類、iteration、smooth valueを比較する。
|
||||
- source、ABI、pixel mapping、tile seam、SIMD/scalar、解析的内部証明、Module clone、配布物hash、文書内の生成値を同じcommandで検証する。
|
||||
- v18監査はarchiveと明記し、現renderer baselineを別JSONにする。
|
||||
|
||||
Exit gate: 全kernelをsourceから再現buildでき、version付きsceneとoracleで数値baselineを再生成でき、全成果物hashと文書内の生成値が一致する。過去baseline欠落は明示的な`not-verifiable`でありpassにしない。
|
||||
|
||||
### Phase 0B — 固定browser baseline
|
||||
|
||||
- desktop、mobile相当、4Kでcold / warmを測る。
|
||||
- first preview、Covered完了、Refined完了、idle job/draw、peak memory、long taskを記録する。
|
||||
- 現行`exactDeepPixel`とは独立した、複数精度一致と誤差上限を持つ高精度reference実装で、分類、iteration、smooth valueを比較する。
|
||||
- v18監査はarchiveと明記し、v22 baselineを別JSONにする。
|
||||
- Hosted / Standalone、SIMD / scalar、Worker / Workerなしを対象構成matrixに従って分けて実行する。
|
||||
- viewportのCSS寸法だけでDPRを模擬しない。mobile / desktop / 4Kは要求DPRを持つ別browser contextまたは別実機runとし、各runの実viewport・実DPR・browser build・OS・電源・試行数を保存する。
|
||||
- visualはraw pixelまたはlinear-light fieldのversion付きgoldenと比較し、hash文字列が生成できただけではpassにしない。
|
||||
|
||||
Exit gate: 全kernelを再現buildでき、v22の速度・memory・数値baselineを同じcommandで再生成できる。
|
||||
Exit gate: 対象profileごとのbrowser acceptanceが合格し、cold / warm、操作p95、visual、idle、long task、observed memory、Export、accessibilityのraw結果を保存する。binding不在などで未実施の場合、後続実装は進められるがbrowser性能・操作・表示の達成を主張しない。

## 12. 推奨する最初の実装単位
|
||||
|

|
||||
|
||||
1. v22 baselineと全WASMの再現buildを用意する。
|
||||
1. v22 baselineの有無を機械可読に確定し、現renderer baselineと全WASMの再現buildを用意する。
|
||||
2. 常時RAFと毎frame DOM更新を廃止する。
|
||||
3. wheelをgestureとしてデバウンスし、非表示時のjobを止める。
|
||||
4. Screen Canvasへpixel budgetを設ける。
|
||||
5. deep poolを必要時まで作らない。
|
||||
6. 既存`q`のままPreview時間予算へ`renderPerf`を接続する。
|
||||
7. v22用のidle・gesture・startup・memory回帰テストを追加する。
|
||||
7. version付き現renderer用のidle・gesture・startup・memory回帰テストを追加する。
|
||||
|
||||
この段階ではBLAカーネルやpixel contractをまだ変えない。まずidle負荷、入力応答、Canvas/初期memory、Preview時間を改善する。画素中心変更は、全kernelを再現buildできるPhase 1Bで行う。

# v23 → v24.1.3 WebGPU migration
|
||||
## v24.1.3 browser hotfix
|
||||
|
||||
実WebGPUブラウザで`direct` shaderのparse時に、WGSL予約語`meta` / `smooth`をstorage変数名へ使用していることが判明しました。両識別子を`fieldMeta` / `fieldSmooth`へ改名し、WGSL 16.2 reserved-word listを全shader sourceへ機械照合するtestを追加しました。
|
||||
|
||||
同時に、shader初期化失敗を通常のWebGPU非対応と同じ扱いにしてCPU f64 rendererへ落としていた挙動を廃止しました。旧挙動は数百万pixel × 数百iterationをmain-thread fallbackで実行し、shader errorの直後にUIが極端に重くなる原因でした。v24.1.3ではshader/pipeline failureは描画を停止して明示し、CPU fallbackは`navigator.gpu`がない/adapterがない場合だけ使います。screen pixel budgetも標準約1.5M（desktop）へ縮小しました。

```
|
||||
|
||||
CPU側に残る高精度処理はview座標とreference orbit生成だけで、pixel rendererではありません。
|
||||
|
||||
## BLAを最終版から外した理由
|
||||
|
||||
初期WebGPU版ではCPU f64でBLAを作り、GPU用f32係数へ量子化して評価していました。しかし`swirly-seahorses-z12`を61×39へ高密度化した回帰で、BLAあり経路がbounded pixelをescapedへ反転する反例を検出しました。
|
||||
|
||||
f64で導出した受入半径へf32係数量子化誤差を安全に織り込む設計が未確立だったため、閾値調整で残すのではなくproduction BLAを完全に除去しました。
|
||||
|
||||
## Deep numeric policy
|
||||
|
||||
Deepではpixel offsetを
|
||||
|
||||
```text
|
||||
delta = w * 2^scaleExp
|
||||
```
|
||||
|
||||
として保持します。通常反復はf32の正規化座標で行い、値域が偏った時だけ16 bit単位でrescaleします。
|
||||
|
||||
さらにroundoff上界を追跡します。
|
||||
|
||||
- escape候補で `|z| - error > 2` の時だけescapedを確定
|
||||
- max iteration到達時もabsolute errorがpolicy閾値以下の場合だけ`INTERIOR_LIKELY`
|
||||
- 不確かな場合は`UNKNOWN`
|
||||
|
||||
閾値:
|
||||
|
||||
```text
|
||||
Balanced: 1e-3
|
||||
Strict: 1e-4
|
||||
```
|
||||
|
||||
Strictは同じ1-pass perturbationの受入閾値を厳しくするpolicyです。以前の「Fast → unresolved queue → Strict再実行」は、BLA撤去後には同じ式を二度計算するだけだったため削除しました。
|
||||
|
||||
## 既知反例の固定
|
||||
|
||||
`swirly-seahorses-z12`の61×39 gridで旧版が誤った3 pixelをregressionへ固定しています。
|
||||
|
||||
```text
|
||||
(25,12) oracle bounded
|
||||
(26,15) oracle bounded
|
||||
(27,25) oracle escaped @ 1957
|
||||
```
|
||||
|
||||
v24.1.3ではBalanced/Strictともこれらを誤分類せず`UNKNOWN`へ退避します。
|
||||
|
||||
## Presentation / recolor
|
||||
|
||||
数値field (`fieldMeta`, `fieldSmooth`) はGPU常駐です。色変更はGPU recolorだけで、Mandelbrot反復を再実行しません。
|
||||
|
||||
描画中にrecolor操作が入った場合はrender tokenを破壊せず`recolorPending`へ集約し、数値frame完了後に最新色を適用します。旧版にあった`rendering=true`残留レースを避けています。
|
||||
|
||||
## Export
|
||||
|
||||
旧巨大Canvas方式は廃止しました。
|
||||
|
||||
- max side 16,384
|
||||
- 512² tile
|
||||
- reusable GPU export workspace
|
||||
- 2×2 AA: 4 GPU samples → GPU linear-light resolve → 1 readback/tile
|
||||
- PNG: scanline bands → deflate stream → PNG chunks
|
||||
- sidecar: exact BigInt view + `unresolvedSamples`
|
||||
|
||||
raw 16K RGBA全体をCanvasへ保持しないため、GPU texture limit回避だけでなくCPU raw-imageメモリも抑えます。
|
||||
|
||||
## Fallback
|
||||
|
||||
WebGPU contextを早期取得すると、pipeline初期化失敗後に同じCanvasを2Dへ切り替えられません。v24.1.3ではshader/pipeline作成を先に行い、成功後にWebGPU canvas contextを取得します。
|
||||
|
||||
WebGPU unavailable時はshallow f64 fallbackのみです。deepをNumberへunderflowさせて描画する経路は削除しました。
|
||||
|
||||
## 削除したv23 production資産
|
||||
|
||||
- deep WASM renderer / Worker pool
|
||||
- BLA WASM renderer
|
||||
- color WASM
|
||||
- BigInt direct pixel renderer
|
||||
- CPU field → ImageData hot path
|
||||
- Canvas detail tile cache
|
||||
- Validated direct Export
|
||||
|
||||
BigInt direct相当はテストoracleにのみ存在します。

# Mandelbrot Deep Zoom v24.1.3 — WebGPU
|
||||
|
||||
軽量な操作表示と、画素中心規約・数値field・境界AA・高精度出力を分離したマンデルブロ集合ビューアーです。無条件の「∞」表記は廃止し、現在のbit数、反復上限、未確定数を表示します。
|
||||
v23のCPU/WASM deep pixel rendererを撤去し、画素計算・field・彩色・再投影・高解像度ExportをWebGPUへ移した版です。
|
||||
|
||||
設計判断は[IMPROVEMENT_PROPOSAL.md](IMPROVEMENT_PROPOSAL.md)、実装・検証状況は[IMPLEMENTATION_REPORT.md](IMPLEMENTATION_REPORT.md)、提案ごとの対応と保留条件は[COMPLETION_AUDIT.md](COMPLETION_AUDIT.md)を参照してください。
|
||||
## 数値構成
|
||||
|
||||
## 実行
|
||||
- ViewState: BigInt固定小数点。深度に応じてbit数を自動拡張。
|
||||
- Shallow: WebGPU `f32` direct iteration。f32座標分解能に十分な余裕があるviewだけで使用。
|
||||
- Deep reference: 専用WorkerでBigInt固定小数点orbitを1本生成。referenceはview精度より64 bit高く生成し、さらに+64 bitのguard orbitでcheckpoint照合。
|
||||
- Deep pixels: WebGPU `guarded rescaled f32 perturbation`。spanはmantissa + exponentへ分離し、`1e-400`級でもpixel offsetをf32 absolute値へ潰さない。
|
||||
- Error handling: roundoff上界がescape/bounded判定へ影響し得るpixelは `FIELD_UNKNOWN` にする。UNKNOWNを内部点へ偽装しない。
|
||||
- BLA: **productionでは無効・未搭載**。旧f32量子化BLAで境界pixelのmembership反転を再現したため、再導入していない。
|
||||
|
||||
Standalone版は`index.html`、`script.js`、`kernels.js`の3ファイルを同じディレクトリに置き、`index.html`を直接開けます。
|
||||
旧v23の`Validated direct`は削除しています。v24.1.3のStrictは誤差許容閾値を厳しくする保守的GPU policyで、任意精度direct全画素証明ではありません。PNG sidecarは常に `membershipCertified:false` です。
|
||||
|
||||
配信用Hosted版はPowerShellから生成します。
|
||||
## 描画パイプライン
|
||||
|
||||
```powershell
|
||||
powershell.exe -NoProfile -ExecutionPolicy Bypass -File ./scripts/build-hosted.ps1
|
||||
通常表示ではfieldをGPUに保持します。

生成先は`dist/hosted/`です。`dist/wasm/`も同じoriginで配信し、`_headers`相当のCOOP/COEPとWASM MIME設定を反映してください。Standalone成果物は`./scripts/build-standalone.ps1`で生成できます。
|
||||
パレット・cycle・shift・HQ変更は数値fieldを再計算せずrecolorします。pan / wheel / pinch操作中は直前frameをGPUで再投影し、settle後に新しい数値frameを計算します。
|
||||
|
||||
## v23の主要仕様
|
||||
## Export
|
||||
|
||||
- 静止時の常時RAFとDOM更新を廃止し、invalidate時だけ描画します。
|
||||
- wheel/pinch/pan中は既存frameの再投影だけを行い、110ms停止後にPreviewを1回開始します。
|
||||
- `Reprojected → Preview → Covered → Refined → Validated/検証未完了`を内部状態として分離します。
|
||||
- Coveredは選択したeffective DPRのCanvas全域を実sampleで計算します。固定2100px HQ上限はありません。
|
||||
- 全backendのpixel mappingは`(x+0.5, y+0.5)`です。
|
||||
- escape値と分類をpalette非依存fieldに保持し、色変更では集合を再計算しません。
|
||||
- `ESCAPED / INTERIOR_LIKELY / INTERIOR_PROVEN / UNRESOLVED`を区別し、未確定を内部点と同じ黒として扱いません。
|
||||
- 境界detailは2×2 subsample fieldを保持し、linear-lightでresolveします。
|
||||
- High-quality exportは指定寸法、2×2 AA、進捗、取消、JSON sidecarに対応します。現在の表示を即時保存するQuick snapshotも別操作です。
|
||||
- deep Workerは必要時に1基だけ生成し、deepを離れた時点で大容量instanceとreferenceを退役させます。
|
||||
- cacheとScreen Canvasは端末別の論理byte/pixel budgetで管理します。
|
||||
高解像度PNGは最大辺16,384 pxです。
|
||||
|
||||
処理モードの自動到達点:
|
||||
- 512×512以下のGPU tileで計算。
|
||||
- Export用GPU buffers/textures/readback bufferは固定workspaceを再利用し、tileごとの大量生成を避ける。
|
||||
- 2×2 AAは4 sampleをGPUで計算し、GPUでlinear-light resolveした後、tileにつき1回だけreadback。
|
||||
- 全画像Canvasを確保せず、scanline bandを`CompressionStream('deflate')`へ送りPNGを構築。
|
||||
- sidecar JSONへ`unresolvedSamples`を記録。
|
||||
|
||||
| モード | 自動処理 |
|
||||
|---|---|
|
||||
| 省電力 | 約1MP以下のPreviewで停止 |
|
||||
| 標準 | shallowは2〜4MP。deepは48px幅の初回測定後、約1.4秒予算へ全域gridを調整。境界AAと未確定追加反復は既定で行わない |
|
||||
| 精細 | 4〜8MPの全域描画、境界AA、境界候補の上限付き追加反復 |
|
||||
| 精度優先 | 精細処理後にP／P+64照合を含む検証 |
|
||||
`unresolvedSamples > 0`は、数値policyがそのsampleを安全に分類できなかったことを意味します。
|
||||
|
||||
## 互換構成
|
||||
## WebGPU unavailable
|
||||
|
||||
| 構成 | shallow | deep | 出力 | 備考 |
|
||||
|---|---|---|---|---|
|
||||
| Hosted + SIMD + Worker | WASM SIMD Worker | BLA/perturbation Worker | 全機能 | 推奨 |
|
||||
| Hosted + SIMDなし | scalar payload | scalar deep/BLA | 全機能 | SIMD検査後にscalarを取得 |
|
||||
| Hosted + Workerなし | main WASM | high-precision BigInt direct | 全機能、低速 | deep WASMは取得せずdirectへ移行 |
|
||||
| Standalone `file://` | 埋込WASM | 埋込Worker/WASM | 全機能 | 3ファイル、オフライン可 |
|
||||
| OffscreenCanvasなし | Canvas 2D | 同左 | 全機能 | 現行標準経路 |
|
||||
| SharedArrayBufferなし | tile/chunk取消 | tile/chunk取消 | 全機能 | 現行標準経路 |
|
||||
WebGPUが利用できない場合は浅部のみJavaScript f64 fallbackを使います。deep zoomは誤画像を出さず、「このズーム深度はWebGPUが必要です」と表示します。
|
||||
|
||||
## 検査
|
||||
WebGPU自体が存在しない場合だけ軽量な浅部JavaScript fallbackを使います。**WGSL/shader/pipeline初期化エラー時はCPU全画面fallbackへ自動移行しません**。エラーを表示して停止し、shader不具合を隠したままCPUを占有しない設計です。`webgpu` canvas contextはpipeline作成成功後に取得します。high-performance adapterが得られない場合は通常のadapter requestも再試行します。
|
||||
|
||||
固定toolchainを含む全gateは次で実行します。
|
||||
## v24.1.3 hotfix
|
||||
|
||||
```powershell
|
||||
powershell.exe -NoProfile -ExecutionPolicy Bypass -File ./scripts/test-all.ps1 -RequireToolchain
|
||||
実ブラウザで発覚したWGSL parse errorを修正しました。WGSL 16.2で予約されている`meta` / `smooth`をstorage-buffer変数名に使っていたため、`fieldMeta` / `fieldSmooth`へ変更しています。全shaderをWGSL reserved-word一覧へ照合するNode gate `tests/v24-wgsl-reserved.mjs`も追加しました。
|
||||
|
||||
表示負荷も見直し、標準モードのscreen pixel budgetをdesktop約1.5M / 小型端末約0.75Mへ縮小しました（旧版は約4M / 2M）。省電力は約0.5M、精細は最大約3M、Strictは最大約2Mです。WebGPU非対応時のCPU fallbackは約0.25M pixelに制限します。
|
||||
|
||||
## Standalone
|
||||
|
||||
`index.html`, `gpu-kernels.js`, `script.js`の3ファイルで動作します。外部WGSL fetchはありません。
|
||||
|
||||
```text
|
||||
index.html
|
||||
gpu-kernels.js
|
||||
script.js
|
||||
```
|
||||
|
||||
toolchainなしでsource contractだけ確認する場合は次を実行します。
|
||||
ブラウザが`file://`上でWebGPUを許可しない構成ではlocalhost/HTTPSで開いてください。
|
||||
|
||||
```powershell
|
||||
powershell.exe -NoProfile -ExecutionPolicy Bypass -File ./tests/source-contract.ps1
|
||||
powershell.exe -NoProfile -ExecutionPolicy Bypass -File ./tests/kernel-source-contract.ps1
|
||||
## Test
|
||||
|
||||
```bash
|
||||
npm test
|
||||
npm run build
|
||||
```
|
||||
|
||||
WASM checksumは`./scripts/extract-wasm.ps1`で再生成します。Nodeテストは本体／Worker構文、WASM Module clone、数値精度、解析的内部証明、pixel mapping／contractを検査します。固定sceneは`tests/scenes.json`にあります。HTTPでworkspaceを配信すれば、`tests/browser-benchmark.html`からcold/warm描画、Covered/Refined、idle write、logical memoryをscene corpus単位で採取できます。
|
||||
`npm test`は以下を検査します。
|
||||
|
||||
WASM source buildと昇格gateは[BUILD_REPRODUCIBILITY.md](BUILD_REPRODUCIBILITY.md)を参照してください。v18の旧性能監査は履歴資料であり、v23の基準値ではありません。
|
||||
- JS syntax / source contracts
|
||||
- WGSL reserved-word token audit (`meta`, `smooth`, `ref`等を含む仕様予約語)
|
||||
- 旧C/WASM deep assetがproduction treeに残っていないこと
|
||||
- BigInt reference Worker + guard checkpoints
|
||||
- shallow f32 CPU model vs BigInt oracle
|
||||
- guarded perturbation CPU f32 model vs BigInt oracle
|
||||
- `swirly-seahorses-z12`高密度回帰と既知3反例
|
||||
- BLAがproductionから除去されていること
|
||||
- tile/pixel geometry
|
||||
- `1e-400` / `1e-1000` coordinate formatting
|
||||
- streaming PNG structure / CRC / inflate / abort
|
||||
- real-WebGPU acceptance harnessのJS syntax
|
||||
|
||||
### 実GPU acceptance
|
||||
|
||||
`tests/webgpu-acceptance.html`をWebGPU対応browserで開きます。これは実adapter上でshader compile / compute / readbackを行い、BigInt oracleと比較します。
|
||||
|
||||
必須gate:
|
||||
|
||||
- stable corpus scene: sampled `UNKNOWN = 0`
|
||||
- swirly scene: 25 sample中12以上を確定
|
||||
- `falseEscaped = 0`
|
||||
- `falseBounded = 0`
|
||||
- reference guard mismatch = 0
|
||||
- 既知dense反例で誤分類しない
|
||||
- 1× / 2×2 Export smokeの未確定sample = 0
|
||||
- uncaptured WebGPU validation error = 0
|
||||
|
||||
このリポジトリを生成した実行環境では`navigator.gpu`が公開されなかったため、実adapter gateだけは未実行です。静的/CPU-model gateの代替ではありません。
