# Stage 0 — Premium 3D Feasibility (artifacts)
Technical feasibility checkpoint executed on branch `feature/premium-3d-stage-0` (from
`dan_branch` @ `5cc27c6`, rollback tag `backup/pre-premium-3d-stage-0-20260729-1542`).
**Verdict: `REALTIME_3D_CONDITIONAL`** — desktop real-time 3D is viable on hardware GPU;
mobile real-time 3D is unproven (no real device available) and must ship the hybrid
SVG/low-profile fallback. See [STAGE0_REPORT.md](./STAGE0_REPORT.md).
## Contents

## Reproduce
```bash
npm run build && npm run preview # serves dist on the first free port (3101 in our runs)
node scripts/stage0-benchmark.mjs # 4 profiles × 3 runs × 32 s, writes performance-*.json
node scripts/stage0-camera-shots.mjs # screenshots 05/06
PLAYWRIGHT_START_SERVER=1 npx playwright test e2e/mobile-fallback.spec.ts
```
Headless GPU flags used (without them Chromium falls back to SwiftShader and results are
**not** valid GPU baselines): `--use-gl=angle --use-angle=gl-egl --enable-gpu
--ignore-gpu-blocklist --disable-software-rasterizer --disable-vulkan-surface`.
Prototype mode query grammar: `/?stage0=1&shadows=1&camera=1&post=0&quality=medium&perf=1&adaptive=1&shot=inspection&hud=0`
(shots: `overview`, `inspection`, `route-b`, `route-c`, `route-d`, `safety`).

# STAGE 0 REPORT — Premium 3D Feasibility
Date: 2026-07-29 · Branch: `feature/premium-3d-stage-0` · Executor: Senior Technical Lead / WebGL Performance Engineer (AI agent)

## 1. STAGE_0_STATUS
```text
REALTIME_3D_CONDITIONAL
```
Desktop real-time 3D passed on hardware GPU (NVIDIA GTX 1080): Profile 2 sustained avg 59.5 FPS, p95 17.3 ms, zero context losses, zero memory growth. Mobile real-time 3D is **NOT_TESTED_ON_REAL_DEVICE** — mobile numbers were produced by viewport/UA emulation on the same desktop GPU and cannot validate Adreno/Mali/Apple silicon. Therefore: desktop = real-time approved in substance; mobile = hybrid SVG/low-profile fallback required until validated on real hardware.
Formal threshold note (no inflation): the strict "min FPS ≥ 40 / ≥ 30" criterion is missed by every desktop profile (min 21.6–33.4). The dips are isolated startup hitches, not sustained jank — p99 frame time is 19.1–29.1 ms and across all 12 runs there were ≤ 3 frames > 33 ms per 32 s run and exactly 1 frame > 50 ms in total (first-run shader compilation). Sustained performance is vsync-capped 60 FPS. This is documented, not hidden.

## 2. GIT_SAFETY
| Item | Value |
|---|---|
| Original branch | `dan_branch` |
| Working branch | `feature/premium-3d-stage-0` (created from `dan_branch` HEAD) |
| Original commit | `5cc27c6` — "chore: add unique assets from other branches into dan_branch" |
| Current commit | `5cc27c6` — **unchanged, no commits created** |
| Rollback tag | `backup/pre-premium-3d-stage-0-20260729-1542` (local, not pushed) |
| Working tree before | clean (verified with `git status --short` at session start) |
| Working tree after | 12 modified files + 8 untracked entries (all Stage 0 scope, listed in §14) |
| Push status | **NO push performed** |
| Merge/rebase status | **NO merge, NO rebase**; `main`, `dan_branch`, `feature/maximum-demo-realism`, remotes, tags and history untouched |
Session cleanup: 6 `core.*` crash dumps (~1.4 GB) produced by my own headless-Chromium GPU flag probing at 15:51 were removed from the working tree; they were never part of the project.

## 3. VERIFIED_FINDINGS (STAGE_0_FACT_CHECK)
Every architectural claim was checked against the code before changes:
| # | Claim from audit | Verdict | Evidence |
|---|---|---|---|
| 1 | Cinematic camera exists but is disabled | **CONFIRMED** | `src/domain/cinematicCamera.ts` (modes + phase binding + viewport-specific presets + tests); controller mounted but playback-gated in `SorterDigitalTwinContinuous.tsx` |
| 2 | `width < 640` ⇒ false "WebGL unavailable" | **CONFIRMED** | `src/pages/MainPage.tsx` (`prefer3DByDefault(width, webgl)`) and `src/components/ThreeFallback.tsx` misleading English text; full SVG fallback (`src/components/SorterScene.tsx`) existed but was unused on the main page |
| 3 | Real GPU FPS never measured (all ~9 FPS figures were SwiftShader) | **CONFIRMED** | `docs/HARDWARE_BENCHMARK_RUNBOOK.md`, `docs/PERFORMANCE_BASELINE.md` — historical numbers are software-rendered; fixed by this Stage 0 (first hardware-GPU measurements) |
| 4 | `new THREE.BoxGeometry()` inside render, no dispose | **CONFIRMED** | `src/components/ThreeD/SortingZones3D.tsx` `RollCage` — per-render geometry creation without cleanup |
| 5 | Cached STL geometry mutated in place (`.center()`, `.computeVertexNormals()` on shared loader cache) | **CONFIRMED** | `src/components/ThreeD/PhysicalPlaybackItem.tsx`, `src/components/ThreeD/STLModel.tsx` |
| 6 | `useLoader` inside `try/catch` | **CONFIRMED** | `STLModel.tsx` — hook-in-try/catch anti-pattern |
| 7 | `use-2d-fallback` is a dead event (dispatched, never consumed) | **CONFIRMED** | `ThreeErrorBoundary.tsx` dispatched it; no listener existed anywhere in `src/` |
| 8 | `webglcontextrestored` not handled (no recovery path) | **CONFIRMED** | only `webglcontextlost` existed in `SorterDigitalTwinContinuous.tsx` / `useWebGL.ts` |
| 9 | `adaptQuality()` implemented but never called | **CONFIRMED** | `src/domain/qualityMode.ts` exported it; zero call sites before Stage 0 |
| 10 | Quality presets carry unused fields (`dprMax`, `rollerDetail`, …) | **CONFIRMED** | `qualityMode.ts`; only `shadows`/`antialias`/`maxVisibleItems` were wired |
| 11 | No post-processing in project | **CONFIRMED** | no `postprocessing` dependency before Stage 0 |
| 12 | Deterministic domain, 166 unit tests, 16 e2e, 10 visual snapshots | **CONFIRMED** | `npm test` → 166/166; Playwright suite; `e2e/visual.spec.ts-snapshots/` (10 PNGs) |
---
## 4. IMPLEMENTED_CHANGES
| Изменение | Файл | Причина | Риск | Проверка |
|---|---|---|---|---|
| Stage 0 prototype mode: query-param parser, device-signal collection, prototype quality chooser, shot→phase adapter | `src/domain/stage0.ts` (new) | Isolated experiment mode; default route untouched | Low — pure functions, no side effects | unit + e2e prototype tests; `?stage0=1` only |
| Playback→simulation adapter for SVG fallback | `src/domain/playbackAdapter.ts` (new) | Drive existing `SorterScene` SVG from the same playback state (determinism) | Low — pure mapping | e2e 390×844 play/pause drives SVG |
| Honest mobile fallback: SVG scene + Russian "Облегчённый режим" badge; misleading "WebGL not available" removed; details link reachable | `src/pages/MainPage.tsx`, `src/styles.css` | Critical UX defect #2 | Medium — main page layout | e2e 390×844 + no-WebGL tests, screenshot 04 |
| WebGL context recovery: `webglcontextlost` keeps canvas mounted (hidden) 12 s for a single safe retry on `webglcontextrestored`; second loss parks SVG fallback forever; no error loop | `src/pages/MainPage.tsx`, `src/components/ThreeD/SorterDigitalTwinContinuous.tsx` | Finding #8; no fake recovery | Medium — lifecycle | e2e context-loss test (forced via `WEBGL_lose_context`), screenshot 07 |
| Dead `use-2d-fallback` event replaced by explicit `onUse2D` callback prop | `ThreeErrorBoundary.tsx`, `ProductDemoSection.tsx` | Finding #7 | Low — explicit contract | tsc, unit, e2e details page |
| Leak fix: `EdgesGeometry` memoized + disposed instead of per-render `new BoxGeometry` | `SortingZones3D.tsx` | Finding #4 | Low — same visuals | memory loop: geometries Δ0 after 10 cycles |
| Leak fix: clone cached STL geometry before `.center()`/`.computeVertexNormals()`, dispose clones | `PhysicalPlaybackItem.tsx`, `STLModel.tsx` | Finding #5 | Low — same visuals | memory loop: textures Δ0, heap no growth |
| `useLoader` out of try/catch: Suspense wrapper + inner loader component | `STLModel.tsx` | Finding #6 | Low — same fallback UX | tsc, unit |
| Cinematic light rig (proto only): dark bg `INDUSTRIAL_PALETTE.backgroundDark`, ambient 0.12, key directional 1.6 `castShadow` 1024 PCFSoft limited frustum, fill 0.35, rim 0.7 cool; `castShadow`/`receiveShadow` only on items, belt frame, floor, gate, pusher, roll cages | `SorterDigitalTwinContinuous.tsx` | Stage 4 feasibility test | Medium — gated behind `stage0` flag | Profile 2 benchmark + screenshots 02/05/06 |
| Renderer setup in proto: `outputColorSpace=SRGB`, `toneMapping=ACESFilmic`, exposure 1.0, `shadowMap.type=PCFSoftShadowMap` | `SorterDigitalTwinContinuous.tsx` | Stage 4.6 | Low — proto only | Profile 2/3 JSONs (`shadows: true`) |
| Cinematic camera enabled in proto + manual shot override (`shot=overview/inspection/route-b/route-c/route-d/safety`) via minimal adapter over existing API; no `setState` in `useFrame` (refs/mutations only) | `SorterDigitalTwinContinuous.tsx`, `stage0.ts` | Stage 5 | Medium — camera math untouched, `cinematicCamera.test.ts` intact | unit camera tests pass; e2e shot test; screenshots 05/06 |
| Post-processing spike: Bloom + Vignette + Noise (+SMAA path), `React.lazy`, only with `post=1` | `PostProcessingSpike.tsx` (new) + deps `@react-three/postprocessing@^3.0.4`, `postprocessing@^6.39.4` | Stage 6 cost measurement | Medium — new deps, fully lazy | bundle-analysis.md (0 B on default route); Profile 3 |
| Adaptive quality in proto: rolling FPS, ≥3 s evaluation interval, cooldown + max switches, DPR applied via R3F `setDpr` (no per-frame React state), logged via `__STAGE0_ADAPT__` | `SorterDigitalTwinContinuous.tsx` (`AdaptiveQualityController`), `stage0.ts` | Stage 8; finding #9 | Medium — proto only | `adaptLog` captured in benchmark JSONs |
| Device classification from `hardwareConcurrency`, `deviceMemory`, `devicePixelRatio`, WebGL renderer (SwiftShader detection), viewport, UA — used only to pick initial quality | `stage0.ts` | Stage 8 | Low — read-only signals | benchmark JSON `device` blocks |
| Favicon 404 console error eliminated (inline SVG favicon) | `index.html` | Only console error in benchmarks | Trivial | console-errors.json |
| Fallback link/badge reachable on 390 px (top padding clears full-width HUD; left-aligned) | `styles.css` | e2e failure fix | Low | e2e 390×844 click-through |
| New e2e coverage: mobile fallback, no-WebGL fallback, context loss/restore double-loss, proto mode, manual shot | `e2e/mobile-fallback.spec.ts` (new, 5 tests) | Stages 3/7/12 | — | 5/5 pass |
| Benchmark harness: 4 profiles × 3 runs × 32 s, warmup, device signals, memory loop ×10, GPU-forced Chromium flags | `scripts/stage0-benchmark.mjs`, `scripts/stage0-gpu-probe.mjs`, `scripts/stage0-camera-shots.mjs` (new) | Stage 9 methodology | — | performance-*.json |
| Static perf test updated to the new conditional `shadows` expression (invariant preserved: shadows never unconditional) | `src/domain/performanceStatic.test.ts` | test matched old syntax | — | unit 166/166 |
Not changed (explicitly out of scope): `classifier.ts`, routing rules, dimension limits, `K >= 0.7`, "габариты → форма" order, expected unit-test values, both 3D engines kept separate, old scene kept, `/details` kept, no UI-kit/design system, no WebGPU/raymarching/SSR/DoF/motion blur/volumetrics/TAA/sound, no hardware/ESP32/KiCad/Python changes.
---
## 5. MOBILE_FALLBACK
**Before**: viewport < 640 px rendered `ThreeFallback` with false English claims ("WebGL not available", "Please use a modern browser") over a dead area; the full SVG fallback (`SorterScene`) existed but was never used on the main page; HUD/controls pretended to drive an invisible canvas.
**After**: two distinct states.
1. **WebGL truly unavailable** (or context permanently dead): SVG `SorterScene` + badge "3D недоступно — показана облегчённая SVG-схема линии" / "3D-сцена прервана…" — no browser-blaming text.
2. **WebGL available but small viewport**: SVG `SorterScene` + honest badge "Облегчённый режим — компактный экран: показана SVG-схема линии". Play/pause/speed drive the visible SVG via the same deterministic playback (`playbackAdapter`); progress stays in sync; `/details` link is visible and clickable above the controls; auto-camera toggle is hidden (no claims about invisible 3D); no black empty area.
**e2e 390×844**: 5/5 pass — no "WebGL not available" text, SVG visible, zero canvases, play/pause drive SVG, details link click-through, zero console/page errors. Screenshot: `screenshots/04-mobile-svg-fallback.png`. Console errors: none (`console-errors.json`).
---
## 6. CINEMATIC_PROTOTYPE
Active only under `?stage0=1` (default route `/` visually unchanged — verified by identical visual-test results before/after, §10).
- **Background**: `INDUSTRIAL_PALETTE.backgroundDark` (existing palette, no new theme).
- **Lighting**: `ambientLight 0.12` + hemisphere 0.3 fill base; key `directionalLight` intensity 1.6 at (6, 9, 4) with `castShadow`, shadow map 1024×1024, `PCFSoftShadowMap`, orthographic frustum ±7, near 1 / far 25, bias −0.0004; fill directional 0.35; rim directional 0.7 `#bcd7ff`.
- **Renderer (proto only)**: `outputColorSpace = SRGBColorSpace`, `toneMapping = ACESFilmicToneMapping`, `toneMappingExposure = 1.0`.
- **Shadow casters/receivers**: products, conveyor frame, floor (receive), stop-gate posts, pusher, roll cages. NOT on route arrows, helper lines, HTML labels, small sensors.
- **Camera**: existing `CinematicCameraController` unblocked in proto; phase-driven (Mode A) or manual `shot=` override (Mode B) via a 20-line adapter (`shotToPhaseCategory`); camera stays alive while paused when a manual shot is set; toggle state is truthful.
- **Effects enabled**: Bloom, Vignette, Noise (post=1 spike), ACES, soft shadows 1024.
- **Intentionally NOT added**: HDRI environments, PBR re-authoring, DoF, motion blur, SSR, volumetric fog, chromatic aberration, TAA, custom/raymarching shaders, WebGPU, sound, scroll-driven storytelling, CAD/GLB pipeline — all Stage 1+ material.

## 7. PERFORMANCE_RESULTS
All rows: **real hardware GPU** — `ANGLE (NVIDIA Corporation, NVIDIA GeForce GTX 1080/PCIe/SSE2, OpenGL ES 3.2)`, WebGL2, Chromium 149 headless, ANGLE gl-egl (flags in README). 3 runs × 32 s each, median reported. `validity: HARDWARE_GPU_VALID` in every JSON.
| Профиль | Устройство | Renderer | Avg FPS | Min FPS | P95 frame | Draw calls | Triangles | Verdict |
|---|---|---|---:|---:|---:|---:|---:|---|
| 1 Baseline | Desktop 1920×1080 DPR1 | GTX 1080 | 60.0 | 33.4 | 17.1 ms | 153 | 2 950 | PASS (reference) |
| 2 Cinematic Light | Desktop 1920×1080 DPR1 | GTX 1080 | 59.5 | 21.6 | 17.3 ms | 170 | 3 158 | PASS sustained (see min-FPS note) |
| 3 Cinematic Full (Bloom+Vignette+Noise) | Desktop 1920×1080 DPR1 | GTX 1080 | 59.8 | 32.7 | 21.7 ms | n/a* | n/a* | PASS — post costs ~4.4 ms p95 vs Profile 2 |
| 4 Mobile Low (DPR1, no shadows/post, reduced items) | Emulated 390×844 DPR3, Android UA | GTX 1080 | 59.7 | 29.9 | 17.3 ms | 151 | 2 898 | PASS on this GPU — **not a phone** |
\* Profile 3 artifact: with the EffectComposer active, `renderer.info.render` resets per internal pass, so "1 call / 1 triangle" is the final fullscreen quad, not the scene. The composer overhead is instead visible in textures (29 vs 3 — composer render targets), programs (17 vs 6), and the p95 delta (+4.4 ms vs Profile 2). Metric limitation documented, not hidden.
Cost breakdown (medians, desktop): cinematic rig + shadows + camera ≈ **free** (p95 17.1 → 17.3 ms, +17 draw calls, +208 tris); post-processing spike ≈ **+4.4 ms p95**; mobile-low ≈ baseline cost.
Min-FPS honesty note: minimums (19.5–33.4 across runs) are single-frame startup hitches (shader compilation on first frames); p99 = 19.1–29.1 ms; total frames > 50 ms across all 12 runs: **1**. No sustained jank, no UI blocking.
**Software-renderer results**: none included. All measurements were forced onto the NVIDIA GPU; a SwiftShader row would be marked `SOFTWARE_RENDERER_NOT_VALID_FOR_GPU_BASELINE` and excluded from the verdict by construction.
Historical context: previous ~9 FPS figures (`docs/PERFORMANCE_BASELINE.md`) were SwiftShader/CPU and are now confirmed non-representative — the same scene renders at 60 FPS on real GPU.

## 8. BUNDLE_IMPACT
Full data: [bundle-analysis.md](./bundle-analysis.md) (before = build of the rollback tag in a temp worktree; after = working tree).
| Metric | Before | After | Δ |
|---|---:|---:|---:|
| Entry `index-*.js` raw / gzip | 330 630 / 98 582 | 339 427 / 101 445 | **+8 797 raw / +2 863 gzip (+2.9 %)** |
| Initial route total (entry + shared, raw) | 343 623 | 351 463 | +7 840 |
| `PostProcessingSpike` chunk (lazy) | — | 163 256 raw / 75 925 gzip | lazy-only, **0 B on default route** |
| `dist/` total | 2 575 307 | 2 752 127 | +176 820 |
| New dependencies | — | `@react-three/postprocessing@^3.0.4`, `postprocessing@^6.39.4` | confined to the lazy chunk |
Prototype chunk is lazy-loaded (`React.lazy` + `post=1` gate): default visitors and even `stage0=1&post=0` users never download it.
---
## 9. MEMORY_AND_CONTEXT
Memory loop (10 remount/playback cycles per profile, from `memoryLoop` in each JSON):
| Profile | Geometries Δ | Textures Δ | Heap Δ (MB) | Note |
|---|---:|---:|---:|---|
| Baseline | 0 | 0 | +8.6 | GC sawtooth 25→47→34, no monotonic growth |
| Cinematic Light | 0 | 0 | −10.0 | ends lower than start |
| Cinematic Full | 0 | 0 | ±(30→51→…) sawtooth | composer targets stable at 29 textures |
| Mobile Low | 0 | 0 | sawtooth | no growth |
Geometry/textures flat after the leak fixes (§4) — previously each roll-cage render allocated new `BoxGeometry` and STL loads mutated shared cache.
Context resilience (e2e, forced via `WEBGL_lose_context`):
| Test | Result |
|---|---|
| `webglcontextlost` → honest SVG fallback with "3D-сцена прервана" badge, canvas kept mounted (hidden) for retry window | PASS (screenshot 07) |
| `webglcontextrestored` → **single safe retry**, 3D canvas visible again, no remount loop | PASS |
| Second loss after consumed retry → permanent SVG fallback, canvas unmounted, **no error loop** | PASS |
| Uncaught errors escaping the boundary across the whole sequence | 0 |
The dead `use-2d-fallback` event was replaced by an explicit `onUse2D` callback — no imitation of recovery remains.
---
## 10. TEST_RESULTS
| Suite | Result | Details |
|---|---|---|
| `npx tsc -b` | PASS | clean |
| `npm test` (unit, 19 files) | **166/166 PASS** | includes updated `performanceStatic.test.ts`; camera tests untouched and green |
| `npm run build` | PASS | ~0.4–0.6 s; chunk warnings pre-existing |
| e2e functional + new Stage 0 spec | **15 + 5 PASS** | `mobile-fallback.spec.ts` 5/5 (390×844 fallback, no-WebGL, context loss/restore, proto mode, manual shot) |
| e2e visual regression | 4 pass / **6 fail — PRE-EXISTING** | identical 6 failures reproduced on the **rollback-tag build** in this environment (snapshots originate from a different machine/renderer); NOT caused by Stage 0; **snapshots NOT overwritten**, per constraints |
| Console errors (benchmarks + e2e) | 0 remaining | single favicon 404 found and fixed (`console-errors.json`) |
| Failed tests and reasons | 6 visual only | environment mismatch, proven by before/after equality |
---
## 11. KNOWN_LIMITATIONS
- **NOT_TESTED_ON_REAL_DEVICE**: no iPhone/Safari, no Android Chrome device, no Telegram WebView. Mobile-low numbers come from a desktop GTX 1080 with a mobile viewport/UA — they validate the code path and its cost model, not a phone GPU.
- Single GPU sample: GTX 1080 (2016 discrete desktop card) is a proxy, not a median laptop; integrated Intel/AMD laptop GPUs untested.
- Min-FPS criterion formally missed (21.6 vs 30/40) due to isolated first-frame shader-compile hitches; sustained metrics (avg, p95, p99) all pass with margin.
- Profile 3 draw-call/triangle metrics are composer-artifacted (see §7).
- 6/10 visual snapshots fail in this environment on both old and new code (pre-existing; origin machine differs).
- Adaptive-quality switching was exercised in proto and logged (`adaptLog`), but on this 60-FPS GPU it never triggered a downgrade — its decision path needs a weaker GPU or artificial FPS caps for full validation.
- `dprMax`, `rollerDetail` preset fields remain partially wired (DPR is driven; roller detail is not — flagged, not hidden).
- Scene-load metric measures first-render readiness (~0.5–0.8 s), not full asset warm-up.
---
## 12. DECISION
**Can a full real-time cinematic website be built?** On desktop: **yes, in substance** — the complete cinematic stack (dark background, 0.12 ambient + key/fill/rim rig, ACES tone mapping, 1024 PCFSoft shadows, cinematic camera) costs ~0.2 ms p95 over baseline and holds 60 FPS vsync-capped on hardware GPU; even adding Bloom+Vignette+Noise keeps p95 at 21.7 ms. The old 9 FPS figure was a SwiftShader artifact and is retired.
**Hybrid approach?** Yes for mobile: real-time 3D on mobile is unproven (no real device available) and must default to the honest SVG fallback / low profile until measured on actual hardware.
**Effects within budget (desktop)**: full lighting rig, ACES, soft shadows 1024 from key objects, cinematic camera, Bloom, Vignette, light Noise.
**Effects to exclude**: DoF, motion blur, SSR, volumetrics, chromatic aberration, TAA, HDRI/PBR re-authoring and scroll-driven storytelling were not validated and stay out until Stage 1 measurements.
**Desktop default profile**: Cinematic Light (Profile 2) — cinematic look at baseline cost; enable post-processing only where measured (or behind adaptive quality).
**Mobile default profile**: SVG fallback (current, fixed in Stage 0); if real-device measurements later pass (≥30 avg / ≥24 min / ≤40 ms p95), Mobile Low (Profile 4) with DPR 1, no shadows, no post, reduced items.
---
## 13. NEXT_STAGE (proposal only — not started)
**Stage 1 — Creative & Asset Foundation** (each item gated by Stage 0 metrics):
1. Real-device validation sprint: one mid-range Android (Chrome) + one iPhone (Safari) + Telegram WebView on both, Profiles 2/4, 3 runs each — converts CONDITIONAL into APPROVED or scopes mobile to hybrid permanently.
2. Creative direction + unified visual language (palette, type, motion spec) built on the validated Profile 2 baseline.
3. CAD→GLB pipeline: export conveyor CAD + official product STEP models from the ZIP archive; PBR material pass; measure per-asset triangle/draw-call budgets against the §7 headroom (+17 draw calls used of a large margin).
4. Scroll-driven storyboard prototype (camera keyframes on top of the existing `cinematicCamera` API; no engine merge yet).
5. Adaptive-quality validation on weak hardware (or FPS-capped) to prove downgrade hysteresis before making it default.
6. Long-term: evaluate merging the two 3D scenes only after asset budgets are known.

# Stage 0 — Bundle Impact Analysis
Measured with `vite build` (production), same machine, same Node toolchain.
- **Before**: rollback tag `backup/pre-premium-3d-stage-0-20260729-1542` (commit `5cc27c6`, `dan_branch` HEAD), built in a temporary git worktree.
- **After**: working tree of `feature/premium-3d-stage-0` (uncommitted Stage 0 changes).
## JavaScript chunks (raw bytes)
| Chunk | Before | After | Δ | Loaded on default route `/`? |
|---|---:|---:|---:|:---|
| `index-*.js` (entry) | 330 630 | 339 427 | **+8 797** | yes |
| `industrialTheme-*.js` (three.js vendor) | 881 879 | 882 923 | +1 044 | yes (3D route) |
| `SorterDigitalTwinContinuous-*.js` | 51 604 | 55 204 | +3 600 | yes (3D route) |
| `SorterDigitalTwin-*.js` | 20 198 | 20 414 | +216 | no (details/lazy) |
| `PerfOverlay-*.js` | 38 363 | 38 363 | 0 | no (perf-gated) |
| `ThreeCapabilityCheck-*.js` | 2 186 | 2 188 | +2 | yes |
| `itemMotion-*.js` | 1 290 | 1 286 | −4 | yes |
| `physicalLayout-*.js` | 12 993 | — (merged into entry split) | −12 993 | — |
| `jsx-runtime-*.js` | — (was inside entry) | 12 036 | +12 036 | yes |
| **`PostProcessingSpike-*.js`** | — | **163 256** | **+163 256** | **NO — lazy, only `?stage0=1&post=1`** |
## Gzip (wire size)
| Metric | Before | After | Δ |
|---|---:|---:|---:|
| entry `index-*.js` gzip | 98 582 | 101 445 | **+2 863 B (+2.9 %)** |
| `PostProcessingSpike-*.js` gzip | — | 75 925 | lazy-only, **0 B on default route** |
| total `dist/` (all assets, raw) | 2 575 307 | 2 752 127 | +176 820 B |
## What the entry delta contains
+2.9 kB gzip on the entry chunk covers: `domain/stage0.ts` (query-param parser, device-signal
collection, prototype quality selection), `domain/playbackAdapter.ts` (playback → SVG simulation
mapping for the honest fallback), and the context-loss/recovery + fallback branching in
`MainPage.tsx` / `SorterDigitalTwinContinuous.tsx`.
## New runtime dependencies
| Package | Version | Where it lands |
|---|---|---|
| `@react-three/postprocessing` | ^3.0.4 | exclusively in lazy `PostProcessingSpike` chunk |
| `postprocessing` | ^6.39.4 | exclusively in lazy `PostProcessingSpike` chunk |
Verified: neither package is reachable from the default-route module graph — the spike component
is `React.lazy(...)`-loaded and rendered only when `stage0.post` is true. The 163 kB (76 kB gzip)
chunk is **never fetched** on `/` or on `/?stage0=1` without `post=1`.
## Verdict
- Initial-bundle regression: **+2.9 kB gzip — negligible**.
- Prototype/post-processing weight: fully isolated in a lazy chunk (production visitors pay 0 B).
- Stage 0 bundle budget: **PASSED**.

# Stage 1 — Real 3D Models + Physical Fidelity: artifacts
Status: **PARTIAL_REAL_MODELS_INTEGRATED** — all 9 official product models integrated and
dimension-validated; conveyor stays procedural (`BLOCKED_BY_CAD_CONVERSION`, see below).
## Contents
| File | What it is |
|---|---|
| `STAGE1_REPORT.md` | Full Stage 1 report (21 sections, mirrors the stage spec) |
| `real-models-inventory.md` | Source asset inventory: archives, files, SHA-256, sizes |
| `real-models-validation.json` | Machine-generated dimension/budget validation (11/11 PASS) |

(`docs/stage0_premium_3d/performance-cinematic-light.json`), C (real conveyor) is blocked —
see `conversion-pipeline.md`. No fictitious metrics were created.
## Reproduce
```bash
# 1. Validate runtime models against the manifest (writes real-models-validation.json)
node scripts/validate-real-models.mjs
# 2. Benchmarks (app server must run on :3101; PLAYWRIGHT_BASE_URL overrides)
node scripts/stage1-benchmark.mjs
# 3. Evidence screenshots
node scripts/stage1-screenshots.mjs
# 4. Verification mode in the browser
# http://localhost:3101/?stage1=1&verify=real-models
# http://localhost:3101/?stage1=1&verify=real-models&sku=SKU-001
```

# STAGE 1 — REAL 3D MODELS AND PHYSICAL FIDELITY: REPORT
## 1. STAGE_1_STATUS
**PARTIAL_REAL_MODELS_INTEGRATED**
Official products (9/11 SKUs) are real, dimension-validated, and run in the main runtime.
Conveyor remains procedural (`BLOCKED_BY_CAD_CONVERSION` — no CAD kernel in the environment,
FCStd has no tessellated mesh; exact continuation commands documented). 2 SKUs are honest,
marked fallbacks (`NO_EXACT_OFFICIAL_MODEL`).
## 2. EXECUTIVE_SUMMARY
- **Real now**: all 9 official product models from the OZON Tech archives (box-300, lunchbox,
detergent, box-400, pouf, plate, bottle, cylinder, pen) load in the main scene, routes B/C/D,
continuous playback, cinematic camera, and `/details`. Dimensions validated 9/9 within
tolerance max(2 mm, 1 %) by an independent script. Roll cages C/D rebuilt to the real
1200×800×800 mm bounding box as instanced meshes. `/details` 2.5× scale distortion removed.
Laser mount height corrected 1.4 m → 1.15 m to match ground truth. Item Y-placement fixed so
bottom-pivoted models rest on the belt (contact epsilon 0–2 mm).
- **Still procedural**: conveyor frame/belt/gates/pusher (blocked, see §10), sensors rig,
receiver interiors, SKU-010/011 (marked fallbacks), materials (base colors; PBR is Stage 2).
- **Fidelity**: geometry of every moving item in the demo playlist now matches the physical
test set within ≤1.8 % per axis; the installation shell is dimensionally correct
(6000×10000 mm work area, 700 mm belt, 1150 mm laser) but not CAD-derived.
- **Main blocker**: conveyor FCStd conversion (no FreeCAD/Blender/assimp; stage rules forbid
installing them).
## 3. GIT_SAFETY
| Item | Value |
|---|---|
| Base branch | `feature/premium-3d-stage-0` (working tree) |
| Working branch | `feature/premium-3d-stage-1-real-models` |
| Commit | `5cc27c6` (unchanged — no commits made) |
| Stage 0 external backup | `/tmp/ozone-stage0-before-stage1/` (stage0.patch, stage0-binary.patch, status.txt, untracked-files.tar.gz, untracked-list.txt, checksums, package*.json) — verified readable, patch non-empty |
| Stage 1 rollback tag | `backup/pre-premium-3d-stage-1-20260729-2035` |
| Working tree before | 17 modified + 14 untracked (Stage 0 state) |
| Working tree after | 17 modified + 28 untracked (Stage 0 + Stage 1 files) |
| commit / push / merge / rebase | NO / NO / NO / NO |
| Stage 0 changes preserved | YES — all Stage 0 files still modified/untracked, e2e Stage 0 suite green |
## 4. VERIFIED_FINDINGS
FACTS (checked in code, not assumed):
- Stage 0 state confirmed: fallback, context-loss recovery, cinematic camera, perf overlay,
lazy PostProcessingSpike all present and functional after Stage 1 (Stage 0 e2e green).
- Domain geometry is millimetres; `physicalLayout.ts` converts to metres for Three.js
(1 unit = 1 m). `VISUAL_SCALE_MULTIPLIER = 2.5` existed only in `Item3D.tsx` (`/details`) —
**removed**.
- `conveer.FCStd` is a FreeCAD ZIP document containing b-rep (`*.brp`) — no tessellation.
- Official STL set covers 9 of 11 app SKUs; Мешок and Шлем exist in the archive but have no
SKU in the app scenario set (registered as `ARCHIVE_ONLY_MODELS`).
- Detergent (3.6 MB) and pen (2 MB) exceeded the 1.5 MB hard budget → decimated
(vertex clustering, reproducible script).
## 5. SOURCE_ASSET_INVENTORY
See `real-models-inventory.md` (full table with SHA-256). Summary: 9 integrated STLs from
`input_info/doc-1782987733.zip`, 2 archive-only models, 1 FCStd (blocked), 2 app SKUs without
official counterpart.
## 6. CONVERSION_PIPELINE
See `conversion-pipeline.md`. Product path: official STL → analyze (bbox/tris/SHA) →
decimate if over budget → manifest registration → runtime normalization (rotation, mm→m,
bottom-center pivot) → automated validation. All steps dependency-free Node; no system
packages installed; exact commands documented incl. owner-side FreeCAD/Blender conveyor path.
## 7. MODEL_INTEGRATION
| SKU | Before | After | Runtime | Default | Fallback |
|---|---|---|---|---|---|
| SKU-001 Короб 300 | primitive box | real STL 592 tris | box-300.stl | real | primitive |
| SKU-002 ЛанчБокс | primitive | real STL 11 574 tris | lunchbox.stl | real | primitive |
| SKU-003 Моющее | substituted primitive | real decimated STL 29 458 tris | detergent.stl | real | primitive |
| SKU-004 Короб 400 | primitive | real STL 536 tris | box-400.stl | real | primitive |
| SKU-005 Пуфик | substituted capsule | real STL 12 880 tris | pouf.stl | real | primitive |
| SKU-006 Тарелка | primitive disc | real STL 2 504 tris | plate.stl | real | primitive |
| SKU-007 Бутылка | primitive cylinder | real STL 6 522 tris | bottle.stl | real | primitive |
| SKU-008 Цилиндр | primitive | real STL 2 152 tris | cylinder.stl | real | primitive |
| SKU-009 Ручка | substituted box | real decimated STL 4 800 tris, lying demo orientation | pen.stl | real | primitive |
| SKU-010 Boundary 450 | primitive | unchanged primitive, honestly marked | — | fallback | itself |
| SKU-011 Oversized round | substituted helmet STL | honest primitive fallback, marked (no silent substitution) | — | fallback | itself |
## 8. DIMENSION_VALIDATION
From `real-models-validation.json` (machine-generated, 11/11 PASS). Tolerance: max(2 mm, 1 %) per axis, uniform scale only (=1.0 everywhere — no rescaling needed).
| Model | Expected mm (w×d×h) | Measured mm | Max deviation | Result |
|---|---|---|---|---|
| SKU-001 | 300×200×200 | 301×200×200.5 | 0.33 % | PASS |
| SKU-002 | 201×152×62 | 201×152.4×62.3 | 0.48 % | PASS |
| SKU-003 | 259×179×278 | 259.0×179.2×278.2 | 0.13 % | PASS |
| SKU-004 | 401×300×400 | 401×300×400.5 | 0.17 % | PASS |
| SKU-005 | 489×264×489 | 488.9×264×488.9 | 0.02 % | PASS |
| SKU-006 | 210×209×27 | 209.5×209.4×26.5 | 1.75 % | PASS |
| SKU-007 | 91×91×305 | 91.2×91.3×305 | 0.35 % | PASS |
| SKU-008 | 435×50×43 | 435×50×43 | 0 % | PASS |
| SKU-009 | 9×13×148 | 148.5×9×13.1 (lying: rotated) | 0.91 % | PASS |
SKU-010/011: no official expected geometry (fallbacks) — manifest-level PASS.
## 9. AXIS, SCALE AND PIVOT
- All sources are Y-up-ish STLs in millimetres; per-model rotation recorded in the manifest
(`rotation`, `axisMapping` fields). Example: pen's long axis is source Z(148) → rotated to
world X for a physically stable **lying** demo orientation (documented, not physics-simulated).
- Uniform scale = 1.0 for every model (sources already match expected sizes within tolerance);
only the global mm→m conversion is applied.
- Pivot: X/Z = footprint center, Y = geometry bottom (`pivotMode: bottom-center`), baked into a
cloned geometry in `RealItemModel.normalizeGeometryClone` — shared geometry is never mutated.
- Belt contact: `itemPosition3D` now returns belt-surface Y for the item bottom; verified by
`stage1Contacts.test.ts` and visually (screenshot 11). No floating, no sinking (ε 0–2 mm).
## 10. CONVEYOR_FIDELITY
| Node | Source | Status |
|---|---|---|
| Frame / belt / gates / pusher | existing procedural geometry, dimensionally correct (500×700 mm conveyor A, sorter B, 700 mm belt height) | PROCEDURAL_FALLBACK |
| Roll cages C/D | rebuilt: real 1200×800×800 mm bbox, open top, instanced rods/frame/wheels | CAD_DERIVED-equivalent procedural (real dimensions) |
| Sensor/laser rig | procedural, laser mount corrected to 1150 mm | PROCEDURAL |
| `conveer.FCStd` | not converted — no CAD kernel available | **BLOCKED_BY_CAD_CONVERSION** |
Conveyor CAD-derived status: none. Polycount/draw calls of the procedural installation are
unchanged from Stage 0 (within budget: scene total 119–122 draw calls, ~41 k tris in view).
Continuation: `conversion-pipeline.md` §Conveyor.
## 11. SCENE_FIDELITY
Fixed mismatches:
1. `/details` 2.5× visual scale — removed; same manifest transform drives both scenes.
2. Laser mount 1.4 m → 1.15 m (matches `MEASUREMENT_SYSTEM_REPORT.md`; measurement math
unaffected due to existing compensation — business results unchanged).
3. Item Y float (`beltY + 0.12`) — items now rest on the belt plane.
4. Roll cages were abstract transparent boxes — now real-dimensioned readable mesh cages.
5. Pen previously shown as generic box — now the real model in documented lying orientation.
Remaining conventions (declared): procedural conveyor shell, simplified receiver interiors,
no drop physics / center-of-mass simulation (out of stage scope), placeholder materials.
## 12. PERFORMANCE_RESULTS
Hardware: NVIDIA GTX 1080 (ANGLE OpenGL ES 3.2), 3 runs × ≥30 s, median. Full data in the
profile JSONs.
| Profile | GPU | Avg FPS | Min FPS | p5 FPS* | p95 ms | p99 ms | >33 ms | Draw calls | Tris | Load ms | Verdict |
|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|
| A — Stage 0 Cinematic Light (control) | GTX 1080 | 59.5 | — | — | 17.3 | — | — | — | — | — | PASS (baseline) |
| B — Real products | GTX 1080 | 60.0 | 33.6† | ≈59.9 | 17.1 | 20.0 | 0 | 119 | 40 582 | 770 | **PASS** (≥55 FPS, p95 ≤20 ms) |
| C — Real conveyor + products | — | — | — | — | — | — | — | — | — | — | SKIPPED (conveyor blocked) — no fake JSON |
| D — Real models Cinematic Full (post on) | GTX 1080 | 59.7 | 24.9† | ≈59.2 | 21.6 | 27.3 | 1 | 1‡ | 1‡ | 663 | **PASS** (p95 ≤28 ms) |
| E — Low/fallback (SVG) | n/a | — | — | — | — | — | — | — | — | 116–463 | **PASS** (fallback visible, 0 model requests, 0 errors) |
\* p5 derived from per-frame distribution in the JSONs. † one-time startup dips (shader
compile), not sustained. ‡ Profile D draw calls/triangles read 1 because `renderer.info` is
sampled after the post-processing composer (fullscreen quad) — a known sampling artifact, same
as Stage 0's cinematic-full; scene statistics are authoritative in Profile B.
Software renderer (SwiftShader): not used for any verdict.
## 13. BUNDLE_AND_ASSET_IMPACT
See `bundle-impact.md`. Entry JS +287 B raw / **+101 B gzip** vs Stage 0; no new runtime deps;
9 STLs = 3.55 MB static on-demand (initial preload set 1.33 MB ≤ 2.5 MB budget); largest asset
1.47 MB detergent (post-decimation); SVG fallback fetches 0 model bytes.
## 14. MEMORY_AND_CONTEXT
From benchmark runs: geometries 109–110, textures 3 (light) / 29 (post), programs 10–22,
heap 20.8 MB (light) / 52.6 MB (post) — stable across runs, no monotonic growth over repeated
playlist cycling (Stage 0 leak fixes intact). Context losses: 0 in all profiles. Stage 0
context-loss/recovery e2e still green. Real models are cloned-then-baked; source geometries
stay cached and shared — no per-instance duplication.
## 15. MOBILE_AND_FALLBACK
- SVG fallback intact (Profile E + screenshot 16): `main-svg-fallback` renders, playback
controls work, details link works.
- **0 real-model requests** on the fallback path (asserted in e2e and Profile E).
- 390×844 verified. Real devices (iPhone/Android/Telegram WebView): **not tested** — policy
unchanged, mobile real-time 3D still not declared ready.
## 16. TEST_RESULTS
| Suite | Result |
|---|---|
| `npx tsc -b` | PASS |
| `npm test` (unit incl. `modelAssets.test.ts`, `stage1Contacts.test.ts`) | PASS |
| `npm run build` | PASS |
| `scripts/validate-real-models.mjs` | PASS 11/11 (exit 0) |
| Functional e2e (Stage 0 suites + `real-models.spec.ts` 6 tests) | PASS 21/21 |
| Visual regression | 6 expected diffs (03 class C, 04 class D, 05 jam, 06 estop, 07 presentation, 08 details) — verified to be the intended real-model/roll-cage visuals; **goldens NOT overwritten** |
| Console errors | 0 across benchmarks and e2e (`console-errors.json`) |
## 17. KNOWN_LIMITATIONS
- Conveyor not CAD-derived (blocked; documented commands). Profile C unmeasured.
- SKU-010/011 are procedural (no official counterpart) — marked, not hidden.
- Мешок/Шлем have no app SKU; archive-only.
- Demo orientations chosen manually (pen lying); no drop physics.
- Materials are placeholders; transparent-bottle material minimal (Stage 2 scope).
- Mobile untested on real devices; Telegram WebView unverified.
- Visual goldens intentionally stale until a human reviews the 6 expected diffs.
- Profile D renderer.info artifact (post-composer sampling) noted in §12.
## 18. DECISION
- Stage 1 goal (reliable geometric & physical foundation): **achieved for products, partial
for the installation** → honest status `PARTIAL_REAL_MODELS_INTEGRATED`.
- Products real? **Yes** — official sources, checksums, measured dimensions, validated.
- Conveyor real? **No** — procedural, conversion blocked by environment.
- Reality match: item geometry ≤1.8 % per axis vs ground truth; installation dimensions match
ground-truth layout values; installation shape remains schematic.
- Performance budget: **passes** (60 FPS, p95 17.1 ms with real models; ≥45/≥55 thresholds met).
- Stage 2: **can proceed**; conveyor conversion is an environment/tooling task for the owner
(or Stage 2 pre-work with approved tooling).
## 19. NEXT_STAGE (proposal only)
Stage 2 — Visual & Material Fidelity: PBR material authoring for the 9 real models, HDRI
environment, unified visual language, conveyor conversion with approved CAD tooling (then
Profile C), scroll-driven storytelling prototype, real-device mobile validation, possible scene
unification (`/` vs `/details`), GLB+Draco migration.
## 20. FILES_CHANGED
Stage 1 product files (13, within the 25-file scope limit):
`src/data/modelAssets.ts`, `src/components/ThreeD/RealItemModel.tsx` (new),
`src/components/ThreeD/RollCageMesh.tsx` (new), `src/components/ThreeD/RealModelVerification.tsx` (new),

Tests: `src/data/modelAssets.test.ts`, `src/domain/stage1Contacts.test.ts` (new),

Generated assets: `public/models/{detergent,pen,pouf}.stl` (decimated/normalized runtime
copies; other 6 STLs already in tree).
Reports/artifacts: `docs/stage1_real_models/` (this file, README, inventory, pipeline,

# Stage 1 — Bundle & asset impact
Baseline: Stage 0 `bundle-analysis.md` (index 339 427 raw / 101 445 gzip).
Measured on the current working tree build (`vite build`, same machine).
## JavaScript
| Chunk | Stage 0 | Stage 1 | Δ raw | Δ gzip |
|---|---:|---:|---:|---:|
| `index-*.js` (entry, default route) | 339 427 | 339 714 | **+287 B** | **+101 B** |
| `SorterDigitalTwinContinuous-*.js` (3D route) | 55 204 | 55 708 | +504 B | — |
| `industrialTheme-*.js` (three.js vendor) | 882 923 | 882 932 | +9 B | — |
| `PostProcessingSpike-*.js` (lazy, `post=1` only) | 163 256 | 163 256 | 0 | 0 |
Stage 1 product code (manifest, `RealItemModel`, `RollCageMesh`, verification overlays,
stage1 config) fits in **< 1 kB gzip on the default route** — normalization is math on
already-loaded geometry; no new runtime dependency was added.
## 3D assets (loaded on demand, not part of the JS bundle)
| Metric | Value |
|---|---:|
| Total runtime STLs (`public/models`, 9 files) | 3 551 656 B (3.55 MB) |
| Initial scene payload (6 preload SKUs in the demo playlist) | 1 326 900 B (1.33 MB) — budget ≤ 2.5 MB: **PASS** |
| Largest single asset | `detergent.stl` — 1 472 984 B (hard limit 1.5 MB: PASS, after decimation) |
| Lazy assets | detergent/pouf/cylinder load when their playlist case starts |
| Compression | none (binary STL, served statically; GLB+Draco is a Stage 2 option) |
| SVG fallback downloads | 0 model bytes (verified in Profile E + e2e) |
## Dependencies
New runtime dependencies: **none**. New dev tooling: two dependency-free Node scripts
(`stage1-analyze-stl.mjs`, `stage1-decimate-stl.mjs`) + validation/benchmark/screenshot
scripts; `typescript` (existing devDependency) reused by the validator.
## Total `dist/`
2 752 127 B → 5 117 376 B. The +2.37 MB delta is the copied `models/` directory
(static on-demand assets), not JavaScript; wire cost on the default route is the 6-STL
preload set above, fetched only when the 3D scene actually mounts.

# Stage 1 — Conversion pipeline (reproducible)
Constraint honored: **no system packages were installed** (no `apt`/`snap`), nothing was
downloaded. All steps run with Node.js from the project's own toolchain.
## Pipeline per source type
| Source | Tool | Conversion | Runtime format | Reproducible | Status |
|---|---|---|---|---|---|
| Official STL (9 products) | `scripts/stage1-analyze-stl.mjs` (dependency-free Node) | measure: tris, bbox, size → manifest | binary STL (as authored, mm) | yes: `node scripts/stage1-analyze-stl.mjs <file.stl>` | DONE |
| Overweight STL (detergent, pen) | `scripts/stage1-decimate-stl.mjs` (vertex clustering, dependency-free) | weld+cluster on uniform grid, flat normals rebuilt | binary STL | yes: `node scripts/stage1-decimate-stl.mjs <in.stl> <out.stl> <cellMm>` | DONE |
| Runtime normalization | `src/components/ThreeD/RealItemModel.tsx` | rotation → mm→m (÷1000) → bottom-center pivot, baked into a cloned geometry; transforms come only from the manifest | three.js BufferGeometry | yes: manifest-driven, validated | DONE |
| Validation | `scripts/validate-real-models.mjs` | parses manifest (via project `typescript`), re-measures runtime STLs, compares to `worldExpectedMm` with tolerance max(2 mm, 1 %) | `real-models-validation.json` | yes: `node scripts/validate-real-models.mjs` (exit ≠0 on critical failure) | DONE |
| Official STEP | — | — | — | — | NOT USED (STL equivalents exist for every SKU; STEP needs CAD tooling) |
| Conveyor FCStd | — | — | — | — | **BLOCKED_BY_CAD_CONVERSION** |
## Why STL and not GLB
GLB was the preferred target, but producing a trustworthy GLB requires a mesh tool
(Blender/assimp/gltf-transform pipeline) that is not available in this environment and may not
be installed per stage constraints. The spec explicitly allows official STL with separate
normalization, explicit orientation/pivot transforms, automatic bbox verification and a
documented limitation. All four conditions are implemented (`RealItemModel.tsx`,
`validate-real-models.mjs`, this file). STL limitations: no materials/hierarchy — acceptable
for Stage 1 (geometry fidelity is the goal; materials are Stage 2).
## Decimation details (budget enforcement)
| Model | Before | After | Cell size | Shape check |
|---|---:|---:|---:|---|
| Моющее средство | 72 752 tris / 3 638 084 B | 29 458 tris / 1 472 984 B | 2 mm | bbox unchanged within 0.2 mm; validation PASS |
| Ручка | 40 926 tris / 2 046 584 B | 4 800 tris / 240 084 B | 1 mm | bbox unchanged within 0.5 mm; validation PASS |
Both results are committed runtime files; the command above reproduces them from the
extracted sources byte-for-byte given the same cell size.
## Conveyor: exact blocked status and how to continue
Facts:
- `3d_models/conveer.FCStd` is a FreeCAD document (ZIP container with `Document.xml`,
b-rep geometry in `*.brp`/OCCT format). It contains **no tessellated mesh** — a CAD kernel
is required to triangulate it.
- Environment check (executed, not assumed): `freecad`, `freecadcmd`, `blender`, `assimp`,
`meshlabserver`, `openscad` — all absent; Python `trimesh`/`numpy`/`cadquery` — absent.
- Stage rules forbid installing system tools and forbid fake replacement models.
Decision (per spec §13.5): keep the existing **procedural conveyor**, mark the node
`BLOCKED_BY_CAD_CONVERSION`, finish the official products, and provide the exact continuation
command. Stage status therefore cannot be `REAL_MODELS_INTEGRATED`.
Owner-side continuation (any one of):
```bash
# Option A — FreeCAD CLI (official)
freecadcmd -c "import FreeCAD,Import,Mesh; \
doc=FreeCAD.open('3d_models/conveer.FCStd'); \
objs=[o for o in doc.Objects if hasattr(o,'Shape')]; \
Mesh.export(objs,'tools/stage1-assets/source/conveyor.stl')"
# then: node scripts/stage1-analyze-stl.mjs tools/stage1-assets/source/conveyor.stl
# Option B — FreeCAD STEP export + Blender GLB
freecadcmd -c "import FreeCAD,Import; \
doc=FreeCAD.open('3d_models/conveer.FCStd'); \
Import.export([o for o in doc.Objects if hasattr(o,'Shape')],'tools/stage1-assets/source/conveyor.step')"
blender -b -P tools/stage1-assets/convert-step-to-glb.py -- conveyor.step conveyor.glb
```
After conversion: split into `staticFrame / belt / inspectionRig / actuatorMounts`
(spec §13.4), register in `src/data/modelAssets.ts` as a conveyor node, and re-run
`node scripts/validate-real-models.mjs` and `node scripts/stage1-benchmark.mjs` (Profile C is
already wired and will execute once a conveyor runtime asset exists).
## Node dev tooling added
None. All scripts are dependency-free Node 22; `typescript` (already a project devDependency)
is used only by the validation script to load the TS manifest. Nothing lands in the runtime
bundle.

# Stage 1 — Source asset inventory
All sources are official OZON Tech archives already present in the repository.
Nothing was downloaded from the internet. Original ZIPs were not modified.
## Archives
| Archive | Role | Contents (relevant) |
|---|---|---|
| `input_info/doc-1782987733.zip` | Official STL set | `Stl/*.stl` — 11 product models |
| `input_info/doc-1782987706.zip` | Official STEP set | STEP versions of the same products |
| `3d_models/conveer.FCStd` | Conveyor CAD | FreeCAD document (b-rep, no tessellated mesh) |
## Product models (integrated)
| SKU | Model | Source file | Format | Runtime | Runtime SHA-256 (short) | Runtime bytes | Triangles | Status |
|---|---|---|---|---|---|---:|---:|---|
| SKU-001 | Короб 300×200×200 | `Stl/Короб 300х200х200.stl` | binary STL | `/models/box-300.stl` | `4ac9046b…` (source) | 29 684 | 592 | REAL |
| SKU-002 | ЛанчБокс | `Stl/ЛанчБокс.stl` | binary STL | `/models/lunchbox.stl` | — | 578 784 | 11 574 | REAL |
| SKU-003 | Моющее средство | `Stl/Моющее средство.stl` | binary STL | `/models/detergent.stl` | — | 1 472 984 | 29 458 | REAL (decimated 72 752→29 458 tris, 3.6 MB→1.47 MB, cell 2 mm) |
| SKU-004 | Короб 400×400×300 | `Stl/Короб 400х400х300.stl` | binary STL | `/models/box-400.stl` | — | 26 884 | 536 | REAL |
| SKU-005 | Пуфик | `Stl/Пуфик.stl` | binary STL | `/models/pouf.stl` | — | 644 084 | 12 880 | REAL |
| SKU-006 | Тарелка | `Stl/Тарелка.stl` | binary STL | `/models/plate.stl` | — | 125 284 | 2 504 | REAL |
| SKU-007 | Бутылка | `Stl/Бутылка.stl` | binary STL | `/models/bottle.stl` | — | 326 184 | 6 522 | REAL |
| SKU-008 | Цилиндр | `Stl/Цилиндр.stl` | binary STL | `/models/cylinder.stl` | — | 107 684 | 2 152 | REAL |
| SKU-009 | Ручка | `Stl/Ручка.stl` | binary STL | `/models/pen.stl` | — | 240 084 | 4 800 | REAL (decimated 40 926→4 800 tris, 2 MB→240 KB, cell 1 mm) |
Full SHA-256 values and per-axis measurements: `real-models-validation.json` +
`src/data/modelAssets.ts` (single source of truth).
## Honest fallbacks (no exact official model)
| SKU | Model | Status | Reason |
|---|---|---|---|
| SKU-010 | Boundary box 450×320×320 | `NO_EXACT_OFFICIAL_MODEL` | App-specific boundary-probe item, not in the official test set. Procedural box, marked in UI. |
| SKU-011 | Oversized round 500×300×300 | `NO_EXACT_OFFICIAL_MODEL` | App-specific C-priority probe. Procedural cylinder, marked in UI. Not silently substituted with Мешок/Шлем. |
## Archive-only models (present, no SKU in the app scenario set)
| Model | Source | Source SHA-256 (short) | Note |
|---|---|---|---|
| Мешок | `doc-1782987733.zip → Stl/Мешок.stl` | `74b31186…` | ASCII STL, ~183×175×199 mm |
| Шлем | `doc-1782987733.zip → Stl/Шлем.stl` | `660429b2…` | ~280×297×356 mm |
These are registered in `ARCHIVE_ONLY_MODELS` in the manifest so future stages can wire them
without re-inventorying.
## Conveyor
| Object | Source | Format | Status |
|---|---|---|---|
| Conveyor | `3d_models/conveer.FCStd` | FreeCAD b-rep | **BLOCKED_BY_CAD_CONVERSION** — no FreeCAD/Blender/assimp in the environment; FCStd contains no tessellated mesh. Procedural conveyor remains. Reproducible conversion instructions: `conversion-pipeline.md`. |
