## 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。**
|
||||
静的contract、Node数値モデル、build/reproducibility gateはPASS。実WebGPU adapterでのv24.2.3 compile/dispatchはこのコンテナではadapterを取得できないため未実行であり、`tests/webgpu-acceptance.html`を外部実機gateとして残す。
|
||||
|
||||
実GPU未実行を「PASS」とは扱いません。
|
||||
## 主な修正
|
||||
|
||||
## 修正済みの重大事項
|
||||
1. 深部の黒面積/黒点
|
||||
- UNKNOWN reasonを保持。
|
||||
- guarded f32 primary後にUNKNOWN限定double-single correctionを追加。
|
||||
- interior黒とUNKNOWN表示を分離。
|
||||
2. 標準描画範囲
|
||||
- direct/deep overlapを導入。
|
||||
- current-view quality/speed probeを本描画前に実行。
|
||||
- deepが15%以上高速な場合だけdeepを採用。
|
||||
3. Multi-reference
|
||||
- 全画面モデルで費用対効果が低いため撤去。
|
||||
4. Export
|
||||
- 1×/2×2 deep ExportにもDS correctionを統合。
|
||||
- 2×2はsample別unresolved counterを使用。
|
||||
5. 旧BLA
|
||||
- membership反転の既知反例があるため引き続き未搭載。
|
||||
|
||||
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
|
||||
### Primary guarded perturbation
|
||||
|
||||
`guarded-production-equation-cpu-f32-model-not-real-gpu`:
|
||||
canonical 17×11 corpus:
|
||||
|
||||
- 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
|
||||
- z14: false escaped 0 / false bounded 0 / UNKNOWN 0
|
||||
- z20: 0 / 0 / 0
|
||||
- z100: 0 / 0 / 0
|
||||
- period3: 0 / 0 / 0
|
||||
- e280: 0 / 0 / 0
|
||||
- e400: 0 / 0 / 0
|
||||
- swirly: false escaped 0 / false bounded 0 / UNKNOWN 49 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。
|
||||
Dense known regression pixels `(25,12)`, `(26,15)`, `(27,25)`はprimaryでは誤分類せずUNKNOWNへ退避。
|
||||
|
||||
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。
|
||||
### Sparse double-single correction
|
||||
|
||||
## BLA status
|
||||
`swirly-seahorses-z12`, 61×39, 2000 iter:
|
||||
|
||||
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。
|
||||
- oracle guard mismatch: 0
|
||||
- primary UNKNOWN: 478 / 2379
|
||||
- primary false escaped: 0
|
||||
- primary false bounded: 0
|
||||
- corrected: 478
|
||||
- remaining: 0
|
||||
- correction false escaped: 0
|
||||
- correction false bounded: 0
|
||||
- escape iteration mismatch: 5
|
||||
- max escape iteration difference: 374
|
||||
|
||||
## Export audit
|
||||
DS passはfinite-iteration visual classification recoveryとして有効だが、escape iteration equalityは保証しない。
|
||||
|
||||
- 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
|
||||
## Router contract
|
||||
|
||||
- direct coordinate floor: ratio 8
|
||||
- no-probe direct margin: ratio 128
|
||||
- overlap: 8–128
|
||||
- deep required speed advantage: 15%
|
||||
- corrected deep probe UNKNOWN max: 0.5%
|
||||
- class disagreement tolerance: 0
|
||||
- current view probe required; depth profile aloneではrouteしない
|
||||
|
||||
## Performance/迂遠処理監査
|
||||
|
||||
- full-frame high-precision CPU renderer: なし
|
||||
- multi-reference reference build loop: なし
|
||||
- redundant primary→same-f32 strict retry: なし
|
||||
- BLA precompute/evaluate: なし
|
||||
- deep correction: full dispatchだがKNOWN pixelは即return。追加reference生成なし。
|
||||
- Export: reusable 512² workspace、1 readback/tile。
|
||||
- 2×2 Export: 4 numerical samplesを1 command stream内で処理し、1 resolve/1 readback。
|
||||
- presentation/recolor: GPU field常駐。
|
||||
|
||||
## Real WebGPU acceptance
|
||||
|
||||
`tests/webgpu-acceptance.html`は以下を実adapterで検証します。
|
||||
`tests/webgpu-acceptance.html`は以下を要求する。
|
||||
|
||||
- shader compilation
|
||||
- standard / Strict deep dispatch
|
||||
- BigInt reference guard
|
||||
- sampled membership
|
||||
- dense known regressions
|
||||
- Export 1× / 2×2 readback
|
||||
- uncaptured validation errors
|
||||
- production 6 WGSL + benchmark DS Direct 1本の計7 WGSL modules compile/pipeline creation
|
||||
- stable corpus corrected UNKNOWN = 0 on sampled pixels
|
||||
- BigInt P/P+64 guard mismatch = 0
|
||||
- false escaped / false bounded = 0
|
||||
- dense 3 regression pixelsをDS correctionでKNOWNへ回収
|
||||
- overlap view-specific routerがquality gateを通過し、15% speed ruleどおりroute
|
||||
- 1× / 2×2 Export unresolved = 0
|
||||
- uncaptured WebGPU validation/runtime error = 0
|
||||
|
||||
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。
|
||||
この環境では`navigator.gpu`/adapterを実利用できないため、上記hardware gateのみ未判定。
|
||||
|
||||
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
|
||||
## v24.2.3 crossover追加監査
|
||||
|
||||
- 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
|
||||
- DS Direct WGSLはproduction routerへ未接続。
|
||||
- Round-depth benchmark: z0,2,4,6,8,10,12,14,16,20,30,40。
|
||||
- CPU BigInt oracle sweep: `audit/v24-crossover-quality.json`。
|
||||
- Seahorse / 1600×900相当ではf32 material degradation ≈ z6、DS ≈ z10。
|
||||
- corrected Deep CPU modelはz8で1/315 false escapeを検出したため、依然membership certificateではない。
|
||||
- 実GPU timingはこのcontainerではWebGPU adapter不成立のため未測定。実機では診断情報→Backend比較で取得する。
|
||||
|
||||
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。
|
||||
|
||||
## v24.2.3 z12 benchmark hang hotfix
|
||||
|
||||
ユーザー実機でBackend比較が `z12 · deep` から終了しない事象を確認。原因はproduction rendererの無限loopではなく、benchmarkが現在の全画面をDeep primary + DS correctionでwarmup 1回 + 2〜5回反復し、各回を単一の大規模GPU jobとして待っていたこと。1600×900級・z12では1測定だけでも最大10億回規模の反復候補となり、queue completion待ちが極端に長くなり得た。
|
||||
|
||||
修正:
|
||||
|
||||
- speed benchmarkを代表3tile（最大256×144）へ縮小。
|
||||
- actual full-resolution座標を維持したtileX/tileYで測定。
|
||||
- aggregate `ms/pixel` からcurrent canvasのfull-frame時間を換算。
|
||||
- quality gateは従来どおり5 spatial tiles。
|
||||
- GPU batch/reference buildに15 s watchdog。timeout時は明示的errorとし、GPU deviceを破棄して再初期化可能にする。
|
||||
- progress表示を `deep sample 2/3` のように細分化。
|
||||
- crossover JSON formatをv2へ更新し、`speedTiles`, `speedPixels`, `msPerPixel`, `fullMedianMs`を記録。
|
||||
|
||||
このhotfixはproduction backend routing/rendering mathを変更しない。
|
||||
|
||||
|
||||
## v24.2.4 Hybrid experiment preparation
|
||||
|
||||
- Added benchmark-only `DIRECT_DS_GUARDED_WGSL`; production router is unchanged.
|
||||
- Guard metric: approximate `|dz/dc|`; threshold sweep `1e12 / 1e13 / 1e14`.
|
||||
- Added `benchmarkHybrid()` / `renderTileMetaHybrid()` using the existing Deep double-single correction only for DS-marked UNKNOWN pixels.
|
||||
- Added z6/z8/z10/z12 experiment UI and JSON export.
|
||||
- Added CPU BigInt P/P+64 risk-model gate. At risk=1e13, observed DS class errors are all caught at z6/z8/z10 with correction rates 2.8% / 11.1% / 34.6%; z12 correction rate is 91.2%, intentionally indicating the Full-Deep crossover.
|
||||
- Added real-WebGPU acceptance smoke for the Hybrid diagnostic path.
|
||||
|
||||
|
||||
## v24.2.5 Sparse Direct experiment (Audit)
|
||||
|
||||
- The previous sparse-Full-Deep diagnostic is superseded and is not exposed in the UI.
|
||||
- Added `DIRECT_TS_CORRECT_WGSL`, a reference-free three-term f32 expansion correction shader that only processes DS sensitivity UNKNOWN pixels.
|
||||
- Added `benchmarkSparseDirect()` / `renderTileMetaSparseDirect()` and a z6/z8/z10/z12 risk sweep.
|
||||
- Full Deep remains the quality/timing baseline; the Sparse Direct candidate itself does not build or bind a reference orbit.
|
||||
- Production backend routing is unchanged.
|
||||
- Root `index.html` is now a single-file bundle with no external script dependency, specifically to keep diagnostic UI controls functional when the HTML is opened from an archive/temp extraction.
|
||||
- Static single-file UI contract and real-browser click smoke are separate gates; real WebGPU arithmetic still requires a WebGPU-capable browser.
|
||||
|
||||
- Sparse Direct coordinate packing uses exact residual subtraction from BigInt fixed-point into three f32 components; this removed the CPU TD-model class errors caused by the earlier host-Number split.
|
||||
|
||||
## v24.2.6 Fixed96 experiment audit
|
||||
|
||||
- v24.2.5 three-term f32 expansion correction is removed from the active experiment because the real-GPU quality gate produced no viable candidate at z6/z8/z10/z12.
|
||||
- New correction shader: `DIRECT_FIXED96_CORRECT_WGSL`.
|
||||
- Arithmetic is signed Q8.88 in three `u32` limbs; no floating-point expansion is used by the correction pass.
|
||||
- Exact BigInt ViewState coordinates are converted directly to Q8.88 tile base + pixel step on the host; no JS `Number` coordinate round-trip is used.
|
||||
- `tests/v24-fixed96-limb-model.mjs` verifies the limb multiplication/round-shift algorithm against BigInt over 20,000 deterministic products.
|
||||
- `tests/v24-fixed96-model.mjs` verifies the DS sensitivity mask + Q8.88 correction against the BigInt P/P+64 oracle on a 1600×900-equivalent Seahorse grid. Safe thresholds exist at z6/z8/z10/z12 in the CPU preflight.
|
||||
- Experiment output reports every risk threshold, including rejected candidates, with correction rate, remaining UNKNOWN, class mismatch and timing. The former `best risk = none` information loss is removed.
|
||||
- Production routing/rendering remains unchanged.
|
||||
- Root `index.html` remains a single-file bundle; the Fixed96 button handler is embedded and has no sibling-JS dependency when opened from an extracted ZIP.
|
||||
- Real-GPU WGSL compilation/timing remains the decisive acceptance gate.
|
||||
|
||||
|
||||
## v24.2.7 Fixed96 range hotfix audit
|
||||
|
||||
- Root cause: `fx_bad_range()` incorrectly required the Q8.88 top integer byte to be `0x00` or `0xff`, rejecting valid values with magnitude >= 1.
|
||||
- Symptom match: real-GPU experiment reported `correction ~= remain` across z6-z12.
|
||||
- Fix: remove the invalid sign-extension test; use a certain-escape component test at `|component| > 2` before fixed-point magnitude squaring.
|
||||
- Added BigInt coordinate range/step-underflow checks before GPU packing.
|
||||
- Added regression tests for valid Q8.88 values above 1, 20,000 limb multiplication cases, and full limb-orbit iteration equality against exact BigInt Q8.88.
|
||||
|
||||
|
||||
## v24.2.8 Fixed96 true sparse queue audit
|
||||
|
||||
Purpose: remove the v24.2.7 full-screen Fixed96 dispatch and make the diagnostic correction genuinely proportional to risky-pixel count.
|
||||
|
||||
Implementation checks:
|
||||
|
||||
- DS risk shader appends local pixel indices to a storage queue with atomics.
|
||||
- queue capacity equals tile pixel count; overflow is still counted and treated as fatal.
|
||||
- a dedicated finalize shader writes indirect dispatch arguments from the GPU-written queue count.
|
||||
- Fixed96 uses `@workgroup_size(64)` and `dispatchWorkgroupsIndirect`; it no longer launches 8x8 workgroups over the full tile.
|
||||
- Fixed96 validates queue indices and verifies the queued pixel is still UNKNOWN(reason 7).
|
||||
- benchmark and quality paths both run `fixed96QueueIntegrity()` and fail closed on any counter/invariant mismatch.
|
||||
- static queue-integrity model covers zero, 20, 65-entry, overflow, wrong-indirect, processed mismatch and stale-entry cases.
|
||||
- Q8.88 limb multiplication/orbit tests remain unchanged and passing; this revision changes scheduling only.
|
||||
|
||||
Real-GPU timing remains the decisive performance gate.

# v24.2.3 Crossover Benchmark
|
||||
|
||||
## 目的
|
||||
|
||||
標準 `f32 Direct` が十分に速いのにBigInt referenceを伴うDeepへ早く切り替わっている可能性を検証する。Deepを速度目的ではなく「品質上必要になった地点」でのみ使えるよう、`f32 Direct / experimental DS Direct / corrected Deep`を同じ深度列で比較する。
|
||||
|
||||
## 品質モデル
|
||||
|
||||
- Seahorse center: `-0.7453983606667815 + 0.1125046349959942i`
|
||||
- viewport: 1600×900。21×15点を画面全域から間引き、隣接21 pixelの座標分解能も別途検査。
|
||||
- 深度: z0,2,4,6,8,10,12,14,16,20,30,40。`span = 3.4×10^-z`。
|
||||
- oracle: BigInt fixed-point P / P+64一致。
|
||||
- Deep: guarded rescaled f32 perturbation + UNKNOWNのみDS correction。
|
||||
- DS Direct: GPU候補と同じdouble-single arithmeticのCPU `Math.fround`モデル。
|
||||
|
||||
| z | f32 class error | f32 adjacent unique | DS class error | DS adjacent unique | Deep error/UNKNOWN |
|
||||
|---:|---:|---:|---:|---:|---:|

|
||||
| 40 | 100.00% | 1/21 | 0.00% | 1/21 | 0 / 0 |
|
||||
|
||||
## 暫定結論
|
||||
|
||||
1. **f32 Directはz4付近までは実用候補。z6では隣接21 pixelが2値まで潰れ、品質上の限界が明確。** 現在の `ratio < 8` 強制Deepは1600px幅・この中心ではおおむねz4前後で発動するため、少なくとも「Deepを速度で選ぶ」には早すぎる。
|
||||
2. **DS Directはz8まで中間backendとして有望。z10ではclass errorが約3.8%に増え、本命Deepへ移るべき。** 隣接pixel分解能自体はz12まで維持するが、反復誤差が先に品質を制限する。
|
||||
3. **Deepは廃止できない。** f32はz6、DSもz10付近から品質が崩れる。Deepは極端な固定費を持つが、より深い領域では唯一の実用候補。
|
||||
4. Deep CPUモデルにはz8で1/315のfalse escapeが残るため、Deepもmembership certificateではない。これは既存の`membershipCertified:false`方針と整合する。
|
||||
|
||||
## 実GPU速度ベンチ
|
||||
|
||||
このコンテナではWebGPU adapterを取得できないため、GPU時間は測定できない。代わりに本体の診断情報へ **Backend比較** を追加した。
|
||||
|
||||
v24.2.2では各深度を現在のcanvas全画面でwarmup+複数回測定していたため、z12 Deepで巨大dispatchが長時間GPU queueを占有するケースがあった。v24.2.3では速度計測を現在のview座標上の代表3タイル（各最大256×144）に限定し、合計時間から `ms/pixel` を算出して現在の全画面へ換算する。品質は別の5タイルで比較する。各GPU batch/reference buildには15秒watchdogがあり、永久待ちはしない。
|
||||
|
||||
実機では同じ深度列を次の3方式により測定する。
|
||||
|
||||
- `f32`: 標準numeric kernel。
|
||||
- `DS`: experimental whole-frame double-single direct kernel。production routerには未接続。
|
||||
- `Deep warm`: reference cache済みのDeep primary + DS correction。
|
||||
- `Deep cold`: `Deep warm + verified BigInt reference build`。
|
||||
各候補のqualityはactual full-resolution座標上の5領域でcorrected Deepと比較し、class mismatch / escape-iteration mismatch / UNKNOWN率をJSONへ記録する。速度JSONにはspeedTiles / speedPixels / msPerPixel / fullMedianMsを保存する。Deep自体の絶対品質は上記BigInt CPU oracle reportを参照する。
|
||||
|
||||
## 次のrouter候補
|
||||
|
||||
実GPU結果が得られたら、backendは「速度だけ」ではなく次で選ぶ。
|
||||
|
||||
```text
|
||||
f32 quality OK → f32/DS/Deep のうち最速
|
||||
f32 NG, DS quality OK → DS/Deep のうち最速
|
||||
DS NG → Deep
|
||||
```
|
||||
|
||||
DeepにBLAがない現在、同じiteration数で`f32 Direct`よりDeep numeric kernelが速くなる理由はほぼない。Deepの役割は速度ではなく座標/反復精度であり、速度比較の本命は **DS cold cost vs Deep cold/warm cost** になる。

|
||||
## Purpose
|
||||
|
||||
The previous three-term f32 expansion correction failed the real-GPU quality gate on every tested depth. v24.2.6 keeps the DS sensitivity gate but replaces the correction arithmetic with deterministic integer fixed-point operations.
|
||||
|
||||
Pipeline:
|
||||
|
||||
```text
|
||||
DS Direct + |dz/dc| risk gate
|
||||
-> risky pixel indices compacted into GPU u32 queue
|
||||
-> GPU finalize writes indirect workgroup count
|
||||
-> dispatchWorkgroupsIndirect
|
||||
-> signed Q8.88 Direct runs only queued pixels
|
||||
-> compare against corrected Full Deep
|
||||
```
|
||||
|
||||
The Fixed96 correction does not bind or build a deep reference.
|
||||
|
||||
## Arithmetic
|
||||
|
||||
- width: 96 bits
|
||||
- format: signed Q8.88 two's complement
|
||||
- storage: 3 × `u32`
|
||||
- multiplication: exact 32×32→64 decomposition from 16-bit partial products, 96×96 accumulation into six 32-bit limbs, then round-and-shift by 88 bits
|
||||
- coordinates: packed directly from the BigInt ViewState into Q8.88; JavaScript `Number` is not used as an intermediate
|
||||
|
||||
Q8.88 is intended only for the z6–z12 transition experiment. It is not proposed as an unlimited deep renderer.
|
||||
|
||||
## Measurements
|
||||
|
||||
For z6 / z8 / z10 / z12 and risk `1e11 / 1e12 / 1e13 / 1e14`, the UI reports every candidate row:
|
||||
|
||||
- extrapolated Fixed96 full-frame time,
|
||||
- Full Deep cold estimate,
|
||||
- speedup,
|
||||
- correction rate,
|
||||
- remaining UNKNOWN,
|
||||
- escaped/bounded class mismatch,
|
||||
- actual Fixed96 dispatch rate,
|
||||
- queue integrity status,
|
||||
- status/failure reason.
|
||||
|
||||
A failed candidate is never collapsed into a single `none` row.
|
||||
|
||||
## CPU preflight
|
||||
|
||||
`tests/v24-fixed96-model.mjs` compares the DS risk gate + exact Q8.88 Direct model with the BigInt P/P+64 oracle on a 1600×900-equivalent Seahorse sample grid. `tests/v24-fixed96-limb-model.mjs` separately verifies the six-limb multiplication algorithm against BigInt for 20,000 deterministic cases.
|
||||
|
||||
These are preflight tests. Real-GPU shader compilation, timing and class comparison remain decisive.
|
||||
|
||||
## Production status
|
||||
|
||||
Diagnostic only. The production router remains unchanged.
|
||||
|
||||
|
||||
## v24.2.7 range hotfix
|
||||
|
||||
v24.2.6 contained a shader bug in `fx_bad_range()`: the top Q8.88 integer byte was treated as if it had to be pure sign-extension. Valid values such as `+1.2` were therefore rejected. Escaping Mandelbrot orbits commonly pass through component magnitudes above 1, so selected correction pixels were counted as `remaining` instead of being written back.
|
||||
|
||||
v24.2.7 removes that invalid test. While the prior state is inside the bailout disk, Q8.88 multiplication is bounded. After each iteration the shader first tests `|Re(z)| > 2 || |Im(z)| > 2` as a mathematically certain escape, and only squares components when both are within ±2. This prevents both the false range rejection and large-value fixed-point wraparound.
|
||||
|
||||
|
||||
## v24.2.8 true sparse queue
|
||||
|
||||
v24.2.7 still launched a 2D Fixed96 workgroup over the whole benchmark tile and returned immediately for non-risk pixels. On SIMD/SIMT hardware this was not sparse enough: a few risky lanes could keep most of a workgroup occupied by the long integer loop.
|
||||
|
||||
v24.2.8 changes the execution topology, not the Q8.88 arithmetic. The guarded DS pass atomically appends each risky local pixel index to a queue. A one-invocation finalize shader writes `ceil(queueCount/64),1,1` to an indirect-argument buffer. The Fixed96 kernel is one-dimensional with `@workgroup_size(64)` and reads exactly one queue entry per invocation. No CPU map/readback occurs between these passes.
|
||||
|
||||
Every timing and quality tile validates queue invariants before its result is accepted. Overflow, wrong indirect arguments, invalid/stale indices or any disagreement between selected/enqueued/processed/corrected counts aborts the experiment rather than producing a misleading timing row.

# v24.2.6 DS + sparse Deep Hybrid Experiment
|
||||
|
||||
## 目的
|
||||
|
||||
v24.2.3実機計測では、Seahorse trackでDS Directはz10/z12でもFull Deepより速い一方、分類品質が不足した。次の実験ではDS Direct全画面を捨てず、数値的に危険なpixelだけDeep補正へ送ることで、z6〜z10の中間帯を高速化できるか測る。
|
||||
|
||||
production routerは変更しない。本ファイルの実験結果が採用条件を満たした場合にのみ次版で `f32 → DS/Hybrid → Full Deep` のrouterを検討する。
|
||||
|
||||
## 実験backend
|
||||
|
||||
`DS guarded direct → UNKNOWN only → existing Deep DS correction`
|
||||
|
||||
DS guarded directはorbitと同時に複素微分 `D = dz/dc` を近似追跡する。
|
||||
|
||||
```
|
||||
D[n+1] = 2 z[n] D[n] + 1
|
||||
```
|
||||
|
||||
`|D| > riskLimit` になったpixelはDS Directの分類を採用せず `FIELD_UNKNOWN / ds-sensitivity` とする。そのpixelだけ既存のBigInt reference + double-single perturbation correctionで再評価する。
|
||||
|
||||
この判定はmembership証明ではなく、DS Directの不安定化を早期に検出する実験用heuristicである。
|
||||
|
||||
## sweep
|
||||
|
||||
- 深度: z6 / z8 / z10 / z12
|
||||
- riskLimit: `1e12`, `1e13`, `1e14`
|
||||
- speed: actual full-resolution座標上の代表3tile（各最大256×144）
|
||||
- quality: 5 spatial tiles
|
||||
- quality reference: corrected Full Deep
|
||||
- cold time: verified BigInt reference buildをHybrid / Full Deep双方へ加算
|
||||
|
||||
診断情報 → **Hybrid実験を開始** を押すとダイアログ表示後に自動開始する。ダイアログ内の **再実行** で同じ設定を再度測定でき、結果はJSON保存できる。
|
||||
|
||||
## CPU事前モデル
|
||||
|
||||
1600×900相当、Seahorse、31×21点、BigInt P/P+64 oracle。`riskLimit=1e13`:
|
||||
|
||||
| depth | raw DS class error | Deep補正対象 | DS class error捕捉率 |
|
||||
|---:|---:|---:|---:|
|
||||
| z6 | 4 / 651 | 18 / 651 = 2.8% | 100% |
|
||||
| z8 | 4 / 651 | 72 / 651 = 11.1% | 100% |
|
||||
| z10 | 10 / 651 | 225 / 651 = 34.6% | 100% |
|
||||
| z12 | 51 / 651 | 594 / 651 = 91.2% | 100% |
|
||||
|
||||
このため事前仮説は次の通り。
|
||||
|
||||
- z6: Hybrid有望。
|
||||
- z8: Hybrid有望。
|
||||
- z10: 補正率約35%でもFull Deepより速いかが主要な計測点。
|
||||
- z12: 約91%をDeepへ送るためHybridの意味が薄く、Full Deepへ切り替える候補。
|
||||
|
||||
## 採用gate
|
||||
|
||||
Hybridをproduction候補にするのは、各viewで以下を全て満たす場合のみ。
|
||||
|
||||
1. corrected Full Deepとのescape/bounded class mismatch = 0。
|
||||
2. correction後remaining UNKNOWN = 0。
|
||||
3. Hybrid cold estimateがFull Deep coldより10%以上高速。
|
||||
4. correction対象率 < 60%。60%以上ならFull Deepを優先。
|
||||
5. 実GPU acceptanceでuncaptured validation/runtime error = 0。
|
||||
|
||||
最終production routerへ昇格する前には、BigInt oracleでdense boundary corpusを別途再検証する。
|
||||
|
||||
## 注意
|
||||
|
||||
- `riskLimit=1e13`はCPU事前モデルから得た候補で、固定仕様ではない。
|
||||
- `|dz/dc|`はcondition proxyであり厳密なroundoff error boundではない。
|
||||
- Hybrid correctionはreference buildを必要とする。ただしv24.2.3実機値ではreference buildはDeep全時間の小部分だったため、主要比較はGPU numeric costとなる。
|
||||
- z12でHybrid補正率が高いことを「失敗」とは扱わない。Full Deepへ切り替えるべき境界を検出することも実験目的である。

## 結論
|
||||
## ファイルの役割
|
||||
|
||||
`IMPROVEMENT_PROPOSAL.md`のv22向け設計判断をrenderer v23へ反映し、ローカル数値検証、WASM再現build、Hosted／Standalone成果物の生成まで実施した。提案は履歴文書であり、修正版のcoverage／Export／受入契約を現行基準とする。実ブラウザでのみ測定できる性能・表示・操作・download検証は、今回の環境にin-app browser bindingがないため未実行である。したがって、実装と確認済みの非ブラウザgate、未確認のbrowser acceptanceを分けて扱う。
|
||||
- `index.html`: UI、canvas、Export dialog。WebGPU実装ロジックは持たない。
|
||||
- `script.js`: BigInt ViewState、reference Worker、WebGPU resource orchestration、backend router、screen/Export pipeline。
|
||||
- `gpu-kernels.js`: production 6 WGSL source + benchmark-only `DS Direct` 1本。DS Directはproduction routerから参照しない。
|
||||
- `tests/v24-sparse-correction-model.mjs`: WGSLと同じf32/double-single式をCPU `Math.fround`で再現し、BigInt oracleと比較する品質gate。
|
||||
- `tests/v24-backend-policy.mjs`: view-specific route policyの純粋ロジック検査。
|
||||
- `tests/webgpu-acceptance.*`: 実GPU compile/dispatch/quality/export gate。
|
||||
- `AUDIT_V24.md`: 現releaseの検査結果と未検証事項。
|
||||
- `MIGRATION_V24.md`: v23からの設計変更と、廃案を含む理由。
|
||||
|
||||
## 実装済み
|
||||
## 今回作成/変更した理由
|
||||
|
||||
- 常時RAFを廃止し、invalidate時だけ動くevent-driven schedulerへ変更した。
|
||||
- wheel／pinch／pan中は再投影だけを行い、settle後に計算を1回開始する。
|
||||
- Preview時間予算を110msへ下げ、cold deep Previewは幅48px以下から開始する。以後は実測MPPでPreview寸法を決める。
|
||||
- 標準deepのCoveredは実測MPPから約1.4秒のpixel budgetを算出する。未計測・再投影のみの場合は保守的MPPを使い、DPR下限は固定比率ではなく長辺64pxとするため4Kでも予算が効く。精細・精度優先ではこの時間適応を行わない。
|
||||
- 処理モードの自動到達点を固定し、省電力はPreview、標準はCovered、精細はRefined、精度優先はValidatedで停止する。標準では境界AAと未確定追加反復を既定で実行しない。
|
||||
- 精細の未確定追加反復は全未確定pixelではなくescape境界候補に限定し、1 viewあたりdeep 384点／shallow 4,096点を上限にする。
|
||||
- `Reprojected → Preview → Covered → Refined → Validated／検証未完了`を分離した。
|
||||
- Coveredはeffective DPRの表示Canvas全域をpixel中心`(x + 0.5, y + 0.5)`で計算する。
|
||||
- escape field、分類、confidenceと彩色を分離し、palette変更時の反復再計算を廃止した。
|
||||
- fieldへ各sampleの実escape iterationを保持し、再着色・未確定継続・Export監査で近似値ではなく同じ数値結果を使う。
|
||||
- adaptive 2×／4× AA、linear-light resolve、byte-budget detail cacheを実装した。
|
||||
- 深部Worker、deep/BLA/color WASM、reference資産を遅延生成し、Worker数を実測とmemory budgetで増減する。
|
||||
- deep/BLA/colorはmainで各1回だけcompileし、compile済み`WebAssembly.Module`をWorkerへstructured cloneする。Worker sourceから埋込payload、palette LUT、RGBA生成の重複を除き、Workerは数値fieldだけを返す。
|
||||
- 通常jobから学習したstrip時間とWorker数をkernel version・端末帯域keyで永続化し、30日TTL、schema version、storage拒否fallbackを付けて次回起動で再利用する。
|
||||
- fixed-point direct、perturbation、rebase、BLA、局所guarded directを共通tile schedulerへ接続した。
|
||||
- deep切替を固定zoom閾値ではなくpixel stepとULPの比、hysteresisで決める。
|
||||
- deep切替とguard bitsへ直近orbitのglitch／未確定／補修率を加え、精度昇格時は低精度で作った基準軌道を破棄して再構築する。
|
||||
- 高精度directを約6msでyieldする非同期処理へ変更し、取消可能にした。
|
||||
- f64解析・収縮判定は`INTERIOR_LIKELY`のまま保持し、ValidatedではP／P+64双方の固定小数点整数不等式で主カージオイド／周期2球を証明できたsampleだけを`INTERIOR_PROVEN`へ昇格する。
|
||||
- 精度優先のdeep描画では、基準軌道もP／P+64で独立再計算して疎なcheckpointとescape位置を照合し、不一致時はglobal reference全体を32 bit昇格して作り直す。
|
||||
- 1×／2×／4×／custom、1×／2×2 AA、Balanced／Validated、進捗、取消に対応する独立tile exportを実装した。
|
||||
- Balanced Exportは未確定数をmetadataへ記録して完了可能とし、Validated Exportは未確定sampleが残る場合にfinal PNGを出さず明示失敗する。
|
||||
- Export sidecarへViewSpec、precision／iteration policy、未確定sample数、backend、全kernel SHA-256、色空間、encoder、paletteを記録する。
|
||||
- version付きURL、戻る／進む、座標・spanの正確値入力／copy、Undo／Redoを実装した。
|
||||
- 初回UI、一般statusと診断status、mobile compact status、keyboard操作、live region、visible focus、44px target、reduced motion／transparencyを実装した。
|
||||
- Hosted版はcontent-hashed外部WASMとstreaming compile、Standalone版は3ファイル直開きを維持した。
|
||||
- cacheは件数ではなくmobile 96 MiB／desktop 192 MiBのlogical byte ledgerで管理する。
|
||||
深部primaryのUNKNOWNを黒として残すことが閲覧品質を下げていたため、追加referenceではなく同じreference上のdouble-single correctionへ変更した。またdirect利用範囲を固定閾値だけで狭めず、actual view上のqualityとGPU速度を測ってdeep採用を限定するためrouterを変更した。
|
||||
|
||||
## 再現buildと配布
|
||||
## 機能検査
|
||||
|
||||
- `src/shallow_kernel.c`、`src/deep_kernel.c`、`src/bla_kernel_v18.c`、`src/color_kernel.c`、`src/abi.json`を配置した。
|
||||
- `toolchain.lock.json`でclang 17.0.6、target、SIMD／scalar flagsを固定した。
|
||||
- clang 17.0.6とNode.js v22.18.0で8 WASMを再buildした。tool配布archiveのURL／SHA-256はrepositoryに保持されていないため、再監査可能な証拠範囲はversion／flags、source hash、生成manifest、golden結果までとする。
|
||||
- shallow、deep、BLA、colorのgoldenとSIMD／scalar同値gateに合格後、payloadと`kernels.js`を昇格した。
|
||||
- `scripts/build-kernels.ps1`は同一payloadだけを自動deduplicateし、異なるCOLOR variantsも正しく保持する。
|
||||
- `scripts/build-hosted.ps1`は現manifest以外の古いcontent-hashed WASMを削除する。
|
||||
`npm test`で以下を自動実行する。

## 性能設計
|
||||
|
||||
現在の非圧縮基準値は、Hosted first view 144,044 bytes、Standalone 172,591 bytesである。詳細なfile hashは`audit/v23-source-baseline.json`に記録した。v22成果物が残っていないため、v22の転送bytes／compile timeに対するnon-regressionは判定不能であり、このv23値を今後の比較起点とする。
|
||||
- overlap probeは本描画前に1回/current-view。
|
||||
- speed probeは最大224×160。
|
||||
- quality probeは最大72×54を5領域。
|
||||
- backend profileは補助診断であり、現在viewのquality probeを省略しない。
|
||||
- DS correctionはUNKNOWNのみ数値ループへ入り、KNOWN pixelは即return。
|
||||
- Export workspaceは512×512固定で再利用。

|

```powershell
|
||||
powershell.exe -NoProfile -ExecutionPolicy Bypass -File scripts/test-all.ps1 -RequireToolchain
|
||||
```
|
||||
## v24.2.3追加作業
|
||||
|
||||
## Browser acceptance gate
|
||||
- `DIRECT_DS_WGSL`: 全画面double-single Directの速度/品質候補。
|
||||
- `runCrossoverBenchmark()`: z0〜z40のround-depth自動比較。
|
||||
- `Backend比較` dialog: 実GPUでf32 / DS / Deep warm / Deep coldを同一解像度で計時しJSON保存。
|
||||
- `tests/v24-crossover-quality.mjs`: 1600×900相当のBigInt P/P+64 oracle品質掃引。
|
||||
- `CROSSOVER_BENCHMARK.md`: 実装意図、CPU品質結果、次routerの判定基準。
|
||||
|
||||
`tests/browser-benchmark.html`は1 runを1 profile・1 buildへ限定し、`?profile=desktop&target=hosted`のように実行する。iframe寸法によるDPR模擬を廃止し、非zero wheelのtransform-to-paint、30回以上のPreview、実際のFine→Refined、raw pixel golden、long task、Export metadata／完了前download／再現性、keyboard操作を自動判定する。HostedとStandaloneを別に開く。visual golden未登録、observed browser/GPU memory、visible focus、page zoom/pinch、screen-reader順序は外部gateとして残り、自動項目が通ってもfull acceptanceを返さない。今回の環境ではbrowser bindingがなかったため、`audit/v23-browser-baseline.json`は`not-run`のままである。
|
||||
現時点ではDS Directは診断専用であり、本体のbackend選択は変更していない。実GPU速度結果なしにproductionへ昇格させないための措置。
|
||||
|
||||
残る実機確認:
|
||||
|
||||
- mobile／desktop／4Kの表示画像とnative coverage
|
||||
- 操作反映p95、Preview／Covered／Refined所要時間
|
||||
- idle時の予約RAF／timer／background job／Canvas・DOM write 0
|
||||
- browser／GPUを含むobserved peak memory
|
||||
- Export寸法、完了前downloadなし、取消、PNG／JSON内容
|
||||
- keyboard-only、focus、44px target、live status、page zoomとcanvas pinchの操作確認
|
||||
## v24.2.4 Hybrid experiment preparation
|
||||
|
||||
このgateが合格するまで、v23の実装完了と数値gate合格は主張できるが、固定実機に対する性能目標の達成は主張しない。
|
||||
- Added benchmark-only `DIRECT_DS_GUARDED_WGSL`; production router is unchanged.
|
||||
- Guard metric: approximate `|dz/dc|`; threshold sweep `1e12 / 1e13 / 1e14`.
|
||||
- Added `benchmarkHybrid()` / `renderTileMetaHybrid()` using the existing Deep double-single correction only for DS-marked UNKNOWN pixels.
|
||||
- Added z6/z8/z10/z12 experiment UI and JSON export.
|
||||
- Added CPU BigInt P/P+64 risk-model gate. At risk=1e13, observed DS class errors are all caught at z6/z8/z10 with correction rates 2.8% / 11.1% / 34.6%; z12 correction rate is 91.2%, intentionally indicating the Full-Deep crossover.
|
||||
- Added real-WebGPU acceptance smoke for the Hybrid diagnostic path.
|
||||
|
||||
browser非依存の現行成果物監査は`audit/v23-browserless-baseline.json`に保存した。公式SHA-256を照合したNode.js v22.18.0 portable binaryで7 executable testsが合格し、source／document contract、851 pixel mapping、1,440 pixel contract、Module cloneを再確認した。deep runtimeは出典付きの混在境界sceneで特性を測るが、値は`measured-not-acceptance`である。v22比較は`not-verifiable`、source-WASM再buildは保存済みprior evidenceの再利用として明示している。
|
||||
|
||||
## v24.2.5 Sparse Direct experiment (Implementation)
|
||||
|
||||
- The previous sparse-Full-Deep diagnostic is superseded and is not exposed in the UI.
|
||||
- Added `DIRECT_TS_CORRECT_WGSL`, a reference-free three-term f32 expansion correction shader that only processes DS sensitivity UNKNOWN pixels.
|
||||
- Added `benchmarkSparseDirect()` / `renderTileMetaSparseDirect()` and a z6/z8/z10/z12 risk sweep.
|
||||
- Full Deep remains the quality/timing baseline; the Sparse Direct candidate itself does not build or bind a reference orbit.
|
||||
- Production backend routing is unchanged.
|
||||
- Root `index.html` is now a single-file bundle with no external script dependency, specifically to keep diagnostic UI controls functional when the HTML is opened from an archive/temp extraction.
|
||||
- Static single-file UI contract and real-browser click smoke are separate gates; real WebGPU arithmetic still requires a WebGPU-capable browser.
|
||||
|
||||
- Sparse Direct coordinate packing uses exact residual subtraction from BigInt fixed-point into three f32 components; this removed the CPU TD-model class errors caused by the earlier host-Number split.
|
||||
|
||||
## v24.2.6 Fixed96 experiment implementation
|
||||
|
||||
Purpose: test a deterministic reference-free correction tier between DS Direct and Full Deep without relying on WGSL float-expansion behavior.
|
||||
|
||||
Implemented:
|
||||
- `DIRECT_FIXED96_CORRECT_WGSL`: signed Q8.88 Direct iteration using 3×u32 values.
|
||||
- exact 32×32→64 multiplication from 16-bit partial products;
|
||||
- 96×96→192 accumulation and rounded Q8.88 reduction;
|
||||
- BigInt→Q8.88 tile coordinate packing;
|
||||
- DS risk gate + Fixed96 UNKNOWN-only correction benchmark;
|
||||
- per-risk failure reporting instead of collapsing all failures to `none`;
|
||||
- single-file ZIP UI contract;
|
||||
- CPU oracle and limb-arithmetic tests.
|
||||
|
||||
Not implemented: production router integration. The experiment must first pass on a real WebGPU adapter.
|
||||
|
||||
|
||||
## v24.2.7 Fixed96 hotfix
|
||||
|
||||
The Fixed96 experiment's real-GPU `remaining` counter exposed an implementation bug rather than an arithmetic-quality limitation. The correction shader's range check confused the 8-bit Q8.88 integer field with redundant sign-extension. The hotfix removes that check and makes bailout ordering overflow-safe: component-certain escape first, exact fixed-point magnitude only inside the ±2 component box.
|
||||
|
||||
|
||||
## v24.2.8 — Fixed96 GPU compact queue
|
||||
|
||||
### Files changed
|
||||
|
||||
- `gpu-kernels.js`: DS risk queue output, indirect-args finalize shader, 1D queue-indexed Fixed96 correction kernel.
|
||||
- `script.js`: queue/indirect buffers, indirect dispatch encoding, per-sample queue integrity verification, queue/dispatch diagnostics in the experiment result.
|
||||
- `tests/v24-fixed96-contract.mjs`: static true-sparse contract.
|
||||
- `tests/v24-fixed96-queue-model.mjs`: fail-closed queue counter/indirect argument model.
|
||||
- `tests/webgpu-acceptance.js`: real-GPU Fixed96 smoke now requires queue integrity and dispatch rate equality.
|
||||
|
||||
### Performance intent
|
||||
|
||||
The previous implementation's numerical correction fraction was sparse, but its GPU invocation topology was not. v24.2.8 makes integer iteration work proportional to the actual queue length. The DS guard remains a full-tile pass because it is the cheap classifier; only the expensive Q8.88 loop is sparse.

# v23 → v24.1.3 WebGPU migration

## v24.1.3 browser hotfix

# v23 → v24.2.3 WebGPU migration / crossover study
|
||||
|
||||
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。
|
||||
## 目的
|
||||
|
||||
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。
|
||||
v23のCPU/WASM deep pixel rendererとWorker poolを廃止し、画素単位のmassively parallel処理をWebGPUへ集約する。CPU高精度処理はBigInt ViewStateとreference orbit生成に限定する。

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。
|
||||
## v24.1系からの品質修正
|
||||
|
||||
## BLAを最終版から外した理由
|
||||
v24.1のguarded f32 perturbationは誤分類を避けるためUNKNOWNへ保守退避する設計だった。境界sceneではUNKNOWNが大きく、interiorに近い暗色表示と相まって黒面積増大/黒点として見えた。
|
||||
|
||||
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。
|
||||
### Multi-reference評価
|
||||
|
||||
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。
|
||||
最初にUNKNOWN macro tileへsecondary BigInt referenceを追加する方式をモデル化した。しかし複数referenceを追加しても`swirly-seahorses-z12`全画面モデルのUNKNOWN回収率が低く、reference生成・転送・再dispatchのコストに見合わなかった。そのためproductionへは採用しない。
|
||||
|
||||
## Deep numeric policy
|
||||
### Sparse double-single correction
|
||||
|
||||
Deepではpixel offsetを
|
||||
代わりにUNKNOWNだけをdouble-single complex perturbationで再評価する。reference orbitはprimaryと共用するため追加BigInt orbitは不要。
|
||||
|
||||
```text
|
||||
delta = w * 2^scaleExp
|
||||
```
|
||||
61×39 dense model / 2000 iter:
|
||||
|
||||
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。
|
||||
- primary UNKNOWN 478
|
||||
- primary membership reversal 0
|
||||
- correction recovered 478
|
||||
- remaining UNKNOWN 0
|
||||
- correction membership reversal 0
|
||||
- escape iteration mismatch 5（最大374）
|
||||
|
||||
さらにroundoff上界を追跡します。
|
||||
したがってcorrectionは表示品質passとして採用し、membership certificateには使わない。
|
||||
|
||||
- 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`
|
||||
## Backend router再設計
|
||||
|
||||
閾値:
|
||||
旧設計のzoom/ULP単一閾値はdeepを早く使いすぎる一方、閾値を下げるだけではdirectの境界誤分類リスクがある。
|
||||
|
||||
```text
|
||||
Balanced: 1e-3
|
||||
Strict: 1e-4
|
||||
```
|
||||
v24.2.1は三領域に分ける。
|
||||
|
||||
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。
|
||||
- ratio < 8: deep必須
|
||||
- ratio >= 128: direct
|
||||
- 8 <= ratio < 128: overlap
|
||||
|
||||
## 既知反例の固定
|
||||
Overlapは本描画前にcurrent-view probeを行う。probeは中心のspeed tileと、画面5領域のquality tileをactual full-resolution pixel座標で評価する。directとDS補正済みdeepのescape/bounded分類差が0、補正後deep UNKNOWN率0.5%以下であることを要求する。そのうえでreference buildを含むdeep予測時間がdirectの85%未満ならdeep、それ以外はdirect。
|
||||
|
||||
`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。
|
||||
深度binの過去profileだけでbackendを決定しない。
|
||||
|
||||
```text
|
||||
(25,12) oracle bounded
|
||||
(26,15) oracle bounded
|
||||
(27,25) oracle escaped @ 1957
|
||||
```
|
||||
## BLAを戻さない理由
|
||||
|
||||
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。
|
||||
f64 BLAをf32係数へ量子化した旧試作は、dense swirly回帰でbounded/escaped membership反転を起こした。量子化誤差を含む安全な受入半径が未確立のため、BLA builder/evaluator/nodeはproduction treeに存在しない。
|
||||
|
||||
## Export
|
||||
|
||||
旧巨大Canvas方式は廃止しました。
|
||||
v24.2.1ではscreenだけでなくExportにもdeep correctionを適用する。
|
||||
|
||||
- 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`
|
||||
1×:
|
||||
|
||||
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。
|
||||
```text
|
||||
primary deep → clear stats → DS correction → color → 1 readback
|
||||
```
|
||||
|
||||
## Fallback
|
||||
2×2:
|
||||
|
||||
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。
|
||||
```text
|
||||
4 samples × (primary deep → DS correction → color)
|
||||
→ GPU linear-light resolve
|
||||
→ 1 readback / tile
|
||||
```
|
||||
|
||||
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。
|
||||
4 sampleのunresolved counterを分離し、sidecarの`unresolvedSamples`へ合計する。
|
||||
|
||||

|
||||
|
||||
BigInt direct相当はテストoracleにのみ存在します。
|
||||
## Validation contract
|
||||
|
||||
productionは`membershipCertified:false`。Strictはprimary error-bound閾値を厳しくするpolicyで、任意精度direct証明ではない。DS correctionもvisual-quality recovery passである。
|
||||
|
||||
|
||||
## v24.2.3 crossover study
|
||||
|
||||
BigInt Deepを廃止するのではなく、使用開始点を後ろへ送れるか検証するためDS Direct候補を追加した。DSはreference構築が不要なためcold latency削減の可能性があるが、WGSL double-singleのコストと品質はGPU依存である。したがってこのreleaseではbenchmark専用とし、実GPU結果を得てからrouterへの昇格を判断する。
|
||||
|
||||
## v24.2.4 diagnostic Hybrid tier
|
||||
|
||||
Crossover実機値でDS Directはz10/z12でもFull Deepより高速だったが、単独では分類品質が不足した。そこでproduction routerを変更する前に、DS Directのcondition proxy `|dz/dc|` を追跡し、危険pixelだけ既存Deep double-single correctionへ送るHybridをbenchmark専用で実装した。
|
||||
|
||||
候補routerはまだ採用しない。実験で `class mismatch=0`, `remaining UNKNOWN=0`, `Hybrid cold < 0.9 × Full Deep cold`, `correction rate < 60%` を満たすviewだけを将来のHybrid overlap候補とする。z12のCPU事前モデルではrisk=1e13で約91%が補正対象となるため、Full Deepへ切り替える境界を検出できる見込み。
|
||||
|
||||
|
||||
## v24.2.5 Sparse Direct experiment (Migration)
|
||||
|
||||
- The previous sparse-Full-Deep diagnostic is superseded and is not exposed in the UI.
|
||||
- Added `DIRECT_TS_CORRECT_WGSL`, a reference-free three-term f32 expansion correction shader that only processes DS sensitivity UNKNOWN pixels.
|
||||
- Added `benchmarkSparseDirect()` / `renderTileMetaSparseDirect()` and a z6/z8/z10/z12 risk sweep.
|
||||
- Full Deep remains the quality/timing baseline; the Sparse Direct candidate itself does not build or bind a reference orbit.
|
||||
- Production backend routing is unchanged.
|
||||
- Root `index.html` is now a single-file bundle with no external script dependency, specifically to keep diagnostic UI controls functional when the HTML is opened from an archive/temp extraction.
|
||||
- Static single-file UI contract and real-browser click smoke are separate gates; real WebGPU arithmetic still requires a WebGPU-capable browser.
|
||||
|
||||
- Sparse Direct coordinate packing uses exact residual subtraction from BigInt fixed-point into three f32 components; this removed the CPU TD-model class errors caused by the earlier host-Number split.
|
||||
|
||||
## v24.2.6 experiment direction
|
||||
|
||||
The float-expansion sparse correction branch is superseded by an integer fixed-point experiment. The transition strategy under test is now:
|
||||
|
||||
```text
|
||||
f32 Direct
|
||||
-> DS Direct
|
||||
-> DS risk gate + sparse Q8.88 Direct
|
||||
-> Full Deep
|
||||
```
|
||||
|
||||
Only the diagnostic branch is changed. Production remains on the existing direct/deep router until real-GPU timing and class gates justify promotion.
|
||||
|
||||
|
||||
## v24.2.7 experiment correction
|
||||
|
||||
Do not interpret v24.2.6 Fixed96 `remaining-unknown` measurements as a Fixed96 feasibility result. They were dominated by an invalid Q8.88 range guard. v24.2.7 is the first build in this branch whose real-GPU Fixed96 correction measurements are suitable for the crossover experiment.
|
||||
|
||||
|
||||
## v24.2.8 experiment scheduling correction
|
||||
|
||||
Fixed96 remains diagnostic and is not part of the production backend router. The correction execution changed from full-tile 2D dispatch with early returns to GPU compact-queue + indirect 1D dispatch. This isolates the experiment's arithmetic feasibility from an avoidable SIMD divergence/scheduling penalty. Adoption decisions must use v24.2.8-or-later timings; v24.2.7 Fixed96 timings are not representative of a sparse implementation.

# Mandelbrot Deep Zoom v24.2.8 — Fixed96 True Sparse Queue Experiment
|
||||
|
||||
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。
|
||||
v24.2.8は、v24.2.7で数値バグを修正したFixed96実験を**真のsparse GPU実行**へ変更した診断版です。DS guarded passが危険pixel indexをGPU queueへcompactし、1-thread finalize passがqueue件数からindirect dispatchを生成、Fixed96 Q8.88 kernelはqueueに入ったpixelだけを処理します。guard→queue→indirect Fixed96の間にCPU readbackはありません。production routerはまだ変更していません。
|
||||
|
||||
## 数値構成
|
||||
## 数値backend
|
||||
|
||||
- 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。
|
||||
- **Direct**: WebGPU `f32` direct iteration。
|
||||
- **Deep primary**: BigInt reference orbit + WebGPU guarded rescaled `f32` perturbation。
|
||||
- **Deep correction**: primaryで`FIELD_UNKNOWN`になったpixelだけ、同じreferenceを用いるdouble-single perturbationで再評価。
|
||||
- **BLA**: productionでは未搭載。旧f32量子化BLAでmembership反転を再現したため再導入していません。
|
||||
- **Multi-reference**: v24.2開発中に全画面モデルを評価したが、追加referenceの生成/dispatchコストに対してUNKNOWN回収が小さかったためproductionから撤去しました。
|
||||
|
||||
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。
|
||||
Deep primaryはroundoff上界を追跡し、escape/bounded判定を安全に受理できないpixelを`UNKNOWN`にします。double-single correctionは表示品質回復用であり、任意精度membership証明ではありません。PNG sidecarの`membershipCertified`は常に`false`です。
|
||||
|
||||
## 描画パイプライン
|
||||
## Direct / Deep router
|
||||
|
||||
通常表示ではfieldをGPUに保持します。
|
||||
単一のzoom閾値でdeepへ切り替えません。

|
||||
1. `pixel step / f32 ULP < 8`ならdirect座標分解能が不足するためdeep必須。
|
||||
2. 比率が128以上ならdirectを即採用。
|
||||
3. 8以上128未満のoverlap帯では、本描画前に**現在のview専用GPU probe**を実行。
|
||||
4. probeではactual full-resolution座標上の複数領域をdirectと「DS補正済みdeep」で比較。
|
||||
5. deep側UNKNOWN率が0.5%以下、escape/bounded分類差0を満たした場合だけ速度比較へ進む。
|
||||
6. reference生成時間を含めてもdeepがdirectより15%以上高速な場合だけdeepを採用。それ以外はdirect。
|
||||
|
||||
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。
|
||||
過去の同深度profileだけで現在viewをdeepへ振ることはありません。profileは診断/平滑化用で、backend選択には現在viewのquality probeを要求します。
|
||||
|
||||
|
||||
## Crossover benchmark
|
||||
|
||||
診断情報の **Backend比較** から、現在のGPUで z0 / 2 / 4 / 6 / 8 / 10 / 12 / 14 / 16 / 20 / 30 / 40 を自動測定できます。
|
||||
|
||||
速度測定は全画面を反復実行しません。現在のview座標上の代表3タイル（最大256×144）を測定して `ms/pixel` を求め、現在のcanvas全体へ換算します。品質比較は別の5領域で実施します。これによりz12以降で全画面Deepを何度も実行してGPU queueが長時間塞がる問題を避けます。reference生成または1回のGPU測定が15秒を超えた場合は明示的に中断します。
|
||||
|
||||
比較するbackend:
|
||||
|
||||
- `f32`: 現行WebGPU標準。
|
||||
- `DS`: experimental whole-frame double-single Direct。**production routerには未接続**。
|
||||
- `Deep warm`: BigInt referenceをcache済みとしたDeep primary + DS correction。
|
||||
- `Deep cold`: verified BigInt reference構築 + Deep warm。
|
||||
|
||||
結果の時間欄は代表tileからの**全画面換算値**です。画面表示に加えJSON保存できます。品質のBigInt oracle掃引結果は `CROSSOVER_BENCHMARK.md` と `audit/v24-crossover-quality.json` を参照してください。CPUモデルではSeahorse trackでf32がz6付近、DS Directがz10付近からmaterial degradationを示し、DSを中間backendとして試す価値があるという結果です。
|
||||
|
||||
## Fixed96 Direct experiment
|
||||
|
||||
診断情報の **Fixed96 Direct実験** から z6 / z8 / z10 / z12 を測定できます。DS Directで `|dz/dc|` を追跡し、`1e11 / 1e12 / 1e13 / 1e14` の各risk thresholdを超えたpixelだけ、reference不要の**96-bit符号付きQ8.88固定小数点Direct**で再評価します。
|
||||
|
||||
v24.2.8では補正対象を`u32` pixel-index queueへcompactします。queue lengthから`dispatchWorkgroupsIndirect()`用の1D workgroup数をGPU内で生成し、Fixed96は**queued pixel数だけ**実行します。従来の「全画面dispatchして非対象laneをreturn」は廃止しました。
|
||||
|
||||
実験システムは各GPU sampleで次をfail-closed検証します。
|
||||
|
||||
- `selected == enqueued == dispatchCount == processed`
|
||||
- queue overflow = 0
|
||||
- indirect workgroup数 = `ceil(enqueued / 64)`
|
||||
- invalid/stale queue entry = 0
|
||||
- `corrected + remain == processed`
|
||||
|
||||
1項目でも崩れれば測定値を採用せず実験をエラー停止します。結果表には`correction`と実際の`dispatch`率を別々に表示し、`queue=ok`を確認できます。速度は代表3tileから全画面換算し、品質は5 spatial tilesでcorrected Full Deepと比較します。production routerへは未接続です。
|
||||
|
||||
### 単一ファイル起動
|
||||
|
||||
rootの `index.html` は `gpu-kernels.js` と `script.js` を内包した単一HTMLです。ZIP内のHTMLをOSが一時展開して開く場合でも、隣接JSファイルに依存しません。
|
||||
|
||||
## Deep correction
|
||||
|
||||
primary deepでUNKNOWNが残った場合、通常/精細/Strictではsparse double-single correctionを1回実行します。KNOWN pixelはshader冒頭で即returnするため、数値反復はUNKNOWNだけです。省電力モードはUNKNOWNが一定量を超えた場合のみ補正します。
|
||||
|
||||
`swirly-seahorses-z12`の61×39 CPU `Math.fround`モデルでは:
|
||||
|
||||
- primary UNKNOWN: 478 / 2379
|
||||
- primary false escape: 0
|
||||
- primary false bounded: 0
|
||||
- DS correction回収: 478 / 478
|
||||
- correction後UNKNOWN: 0
|
||||
- correction false escape / false bounded: 0 / 0
|
||||
|
||||
escape iterationは5 pixelでBigInt oracleと差があり、最大差374 iterationでした。このためDS correctionは「見た目と有限iterationの分類回復」であり、Validated相当の保証には使用しません。
|
||||
|
||||
## UNKNOWN診断
|
||||
|
||||
内部metadataではUNKNOWN理由を分離しています。
|
||||
|
||||
- error-bound
|
||||
- escape-uncertain
|
||||
- reference-end
|
||||
- rebase-gap
|
||||
- range
|
||||
- operation-limit
|
||||
|
||||
未補正UNKNOWNはinteriorの完全な黒と別色で表示され、診断欄に理由別件数が出ます。
|
||||
|
||||
## Export
|
||||
|
||||
高解像度PNGは最大辺16,384 pxです。
|
||||
- 512×512 reusable GPU workspace。
|
||||
- deep Exportでもprimary後にDS correctionを実行。
|
||||
- 2×2 AAは各4 sampleをGPUで数値計算→補正→彩色し、GPU resolve後に1回だけreadback。
|
||||
- 最終画像全体の巨大Canvasは作らず、scanline bandを`CompressionStream('deflate')`へ流すstreaming PNG。
|
||||
- 16384px級の片辺をtile処理可能。
|
||||
- sidecarに`unresolvedSamples`を記録。
|
||||
|
||||
- 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。
|
||||
## Fallback
|
||||
|
||||
`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。
|
||||
WebGPUそのものが利用できない場合だけ軽量JavaScript f64 fallbackを使います。deep zoomはNumber underflow等で誤画像を出さず、「このズーム深度はWebGPUが必要です」と表示して停止します。shader/pipeline failureではCPU全画面rendererへ自動fallbackしません。
|
||||
|
||||
## WebGPU unavailable
|
||||
|
||||
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。
|
||||
|
||||
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。
|
||||
|
||||
## v24.1.3 hotfix
|
||||
|
||||
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
|
||||
```
|
||||
|
||||
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。
|
||||
|
||||
## Test
|
||||
## Build / test
|
||||
|
||||
```bash
|
||||
npm test
|
||||
npm run build
|
||||
```
|
||||
|
||||
`npm test`は以下を検査します。
|
||||
`npm test`には以下を含みます。
|
||||
|
||||
- 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
|
||||
- WGSL reserved-word scan（9 shader。DS Direct / guarded DS / Fixed96 Direct correctionは実験専用）
|
||||
- production source/tree contract
|
||||
- BigInt reference Worker + P/P+64 checkpoint
|
||||
- f32 direct CPU model
|
||||
- view固有adaptive backend router policy
|
||||
- guarded primary deep CPU model
|
||||
- sparse double-single correction CPU model
|
||||
- BLA disabled contract
|
||||
- pixel/export geometry
|
||||
- e400/e1000 exact coordinate formatting
|
||||
- streaming PNG CRC/deflate/abort
|
||||
- real-WebGPU acceptance harnessの静的contract
|
||||
|
||||
### 実GPU acceptance
|
||||
実GPU受入は `tests/webgpu-acceptance.html` をWebGPU対応ブラウザで開いて実行します。これはdirect/deep/DS/Fixed96 Direct shader compile、DS correction、Fixed96 smoke、dense既知反例、view-specific router、1×/2×2 Export readback、uncaptured WebGPU errorを検査します。
|
||||
|
||||
`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。
|
||||
## 配布
|
||||
|
||||
必須gate:
|
||||
`npm run build`で以下を生成します。
|
||||
|
||||
- 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
|
||||
- `dist/standalone/`
|
||||
- `dist/hosted/`
|
||||
|
||||
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。
|
||||
`dist/standalone/` は単一 `index.html`、`dist/hosted/` は `index.html`, `gpu-kernels.js`, `script.js` です。root `index.html` も単一ファイルで、ZIPから展開してそのまま開けます。
