feat: Stage 2D hardware perf PASS, SPEC_DERIVED_CAD mechanism, device-test

Measure GTX 1080 matrix (A/B/C 60 FPS p95~17ms); selective CAD shadows and DPR 1.25; ship SPEC_DERIVED_CAD sorter mechanism GLB/STEP; add /device-test; document domain blocker and phone NOT_TESTED. Co-authored-by: Cursor <cursoragent@cursor.com>

+# STAGE 2D REPORT — Performance Recovery / Real Mechanism / Phone-Ready
+
+## 1. STAGE_2D_STATUS
+
+**PARTIAL_SORTER_PERFORMANCE_AND_MECHANISM**
+
+Hardware GPU performance PASS (GTX 1080). SPEC_DERIVED_CAD mechanism shipped (not author REAL_CAD). Domain/phone blocked or untested. Runtime WebM partial.
+
+## 2. EXECUTIVE_SUMMARY
+
+- Stage 2C performance FAIL root cause: **no hardware measurements** (`NOT_REMEASURED`), not proven low FPS.
+- Stage 2D measured on **NVIDIA GTX 1080** (ANGLE Vulkan): Profiles A/B/C **60 FPS**, p95 ≈17 ms, draws ≤174, tris ≤216k.
+- Optimizations: selective CAD shadows, shadow map 1024, demo DPR 1.25, maxVisibleItems 4.
+- Author junction CAD still missing; created **SPEC_DERIVED_CAD** STEP+GLB from documented PUSHER dimensions; runtime loads GLB (JSX fallback only).
+- Drop 7/7×10/10; runtime/headless hash `7ee15ad3e879a44a` unchanged equal.
+- `/device-test` added; real phone **NOT_TESTED**; `sorter.arhipovdan.ru` still **BLOCKED**.
+
+## 3. GIT_SAFETY
+
+- Backup `/tmp/ozone-before-stage2d/`
+- Tag `backup/pre-stage2d-performance-mechanism-20260730-1241`
+- Branch `feature/ozon-sorter-stage-2d-performance-mechanism`
+
+## 4. PERFORMANCE_ROOT_CAUSE
+
+See `performance-root-cause.md`. Stage 2C FAIL = missing hardware matrix.
+
+## 5. PERFORMANCE_OPTIMIZATIONS
+
+| Change | Before | After | Impact | Tradeoff |
+|---|---|---|---|---|
+| CAD shadow casters | all meshes | frame/belt/gate/inspection/motor | fewer shadow draws | rollers no cast |
+| Shadow map | 2048 | 1024 | cheaper shadows | softer edges |
+| Environment res | 128 | 64 | less GPU | slightly flatter IBL |
+| demo/high dprMax | 1.5 | 1.25 | pixel fill ↓ | less retina sharpness |
+| maxVisibleItems demo | 6 | 4 | fewer SKUs | demo density |
+| Mechanism visual | JSX boxes | SPEC_DERIVED_CAD GLB | CAD source | still not author CAD |
+
+## 6. PERFORMANCE_RESULTS
+
+GPU: NVIDIA GeForce GTX 1080 (ANGLE Vulkan)
+
+| Profile | GPU | Avg FPS | Min | P95 | Physics P95 | Draw calls | Tris | Result |
+|---|---|---|---|---|---|---|---|---|
+| A CAD Light | GTX 1080 | 60 | — | 16.8 | N/A* | 162 | 182k | PASS |
+| B CAD+Physics | GTX 1080 | 60 | — | 17.0 | N/A* | 152 | 197k | PASS |
+| C Full runtime | GTX 1080 | 60 | — | 17.1 | N/A* | 174 | 216k | PASS |
+| D Cinematic full | GTX 1080 | 60 | 33 | 17.1 | N/A* | (instr.) | (instr.) | PASS FPS |
+| E Mobile SVG 390 | policy | — | — | — | — | SVG | — | PASS_SVG_POLICY |
+| E Low 3D 800 | GTX 1080 | 60 | 48 | 17.1 | N/A* | 109 | 177k | PASS |
+
+\*Physics step timing not separately instrumented (fixed 1/60, ≤4 substeps).
+
+## 7. MECHANISM_SOURCE_SEARCH
+
+See `mechanism-source-search.md`. No author junction paddle in any branch/archive.
+
+## 8. MECHANISM_CAD
+
+- Status: **SPEC_DERIVED_CAD**
+- Files: `3d_models/sorter_mechanism.step`, `.params.json`, `public/models/sorter/mechanism-web.glb`
+- Dimensions from PUSHER + mechanism-map (documented)
+
+## 9. RUNTIME_MECHANISM
+
+- Domain: `getPusherState` / kinematic Rapier
+- Collider: cuboid matching PUSHER (parity)
+- Visual: CAD GLB default; JSX Suspense fallback
+
+## 10. RUNTIME_PHYSICS_REALISM
+
+Headless contact PASS; runtime WebM missing → PARTIAL visual.
+
+## 11. DROP_VALIDATION
+
+7/7 × 10/10, 0 teleport, pusher contact on C/D. See `drop-validation.json`.
+
+## 12. RUNTIME_HEADLESS_PARITY
+
+Hash `7ee15ad3e879a44a` equal — PASS.
+
+## 13. REAL_PRODUCT_FIDELITY
+
+Scale unchanged; real STL default preserved.
+
+## 14. MOBILE
+
+`/device-test` + SVG policy at &lt;640px. Real phone NOT_TESTED.
+
+## 15. PUBLIC_DOMAIN
+
+BLOCKED_BY_DEPLOYMENT_ACCESS — openresty/SNI.
+
+## 16. DEPLOYMENT
+
+`:3100` updated Stage 2D; rollback retained.
+
+## 17. TEST_RESULTS
+
+- tsc / vitest 199 / build PASS
+- drop 7/7 PASS
+- stage2c layout e2e previously green
+
+## 18. KNOWN_LIMITATIONS
+
+- Not author REAL_CAD mechanism
+- No FreeCAD binary → STEP+params instead of FCStd
+- No runtime WebM
+- Physics p95 not separately metered
+- Domain/phone incomplete
+- Profile D drawCall counter unreliable under post
+
+## 19. DECISION
+
+| Question | Answer |
+|---|---|
+| Performance FAIL fixed? | YES (root cause was missing data; hardware PASS) |
+| GPU | NVIDIA GTX 1080 |
+| CAD mechanism? | SPEC_DERIVED_CAD (not REAL_CAD) |
+| Contact? | PASS (headless + kinematic) |
+| Runtime falls realistic? | PARTIAL (no WebM) |
+| Runtime/headless? | PASS |
+| Domain? | BLOCKED |
+| Phone? | NOT_TESTED |
+
+## 20. FILES_CHANGED
+
+See git commit.

+# Mechanism source search — Stage 2D
+
+## Scope (read-only)
+
+- Current working tree
+- Local + remote branches (`git branch -a`)
+- Git history (add/delete) for pusher/paddle/diverter/actuator/servo/mechanism/толкатель/заслонка
+- `*.FCStd` / `*.step` / `*.stp` / archives under `input_info/` and `releases/`
+- Git LFS listing
+
+## Findings
+
+| Source | Result |
+|---|---|
+| Author CAD | Only `3d_models/conveer.FCStd` — metering servos + barriers, **no junction paddle** |
+| Archives (`input_info/*.zip`) | No FCStd/STEP paddle/diverter solids |
+| Git history | No deleted junction CAD; Stage 2B added `pusherMotion.ts` + JSX `PusherMechanism` |
+| Branches | No alternate FCStd mechanism on `main` / `dan_branch` / stage2 branches |
+| LFS | Empty / unused for CAD |
+
+## Conclusion
+
+**Author REAL_CAD junction mechanism: MISSING.**
+
+Stage 2D delivers **SPEC_DERIVED_CAD**:

+# Performance root cause — Stage 2C FAIL
+
+## Verdict
+
+Stage 2C `performance: FAIL` was **not** a measured hardware FPS failure.
+
+Evidence from `docs/stage2c_cad_visual/performance-*.json`:
+
+- `status: NOT_REMEASURED` / `measured: null`
+- Explicit note: formal multi-run GPU profile deferred
+
+## Classification
+
+**INSUFFICIENT_HARDWARE_PERFORMANCE_DATA** (Stage 2C) — profiles never run on a hardware renderer.
+
+## Environment (Stage 2D probe)
+
+| Path | Renderer |
+|---|---|
+| Playwright default / SwiftShader | `ANGLE (... SwiftShader Device (Subzero) ...)` |
+| Playwright `--use-angle=vulkan` | `ANGLE (NVIDIA, ... GeForce GTX 1080 ...)` |
+| Host | 2× NVIDIA GeForce GTX 1080 (driver 580.126.09) |
+
+SwiftShader results must **not** be used for PASS/FAIL.
+
+## Likely cost drivers (code audit, pre-optimization)
+
+1. CAD GLB ~159k tris, every mesh `castShadow` when shadows on
+2. Demo quality: `dprMax 1.5`, AA on, PCFSoft shadows
+3. Hybrid Rapier always mounted on continuous twin
+4. Modular belt extensions add extra meshes/rollers
+5. ACES + soft shadows default (Stage 2 premium look)
+
+## Regression narrative
+
+| Stage | Note |
+|---|---|
+| Stage 0 | Cinematic light / optional post — measured in Stage 0 docs |
+| Stage 1 | Real STL products |
+| Stage 2B | CAD GLB + Rapier drops + soft shadows default |
+| Stage 2C | UI/layout/motor cleanup; **no new GPU matrix** → FAIL by omission |
+
+No single commit proves FPS regression without Stage 2C numbers; Stage 2D supplies hardware matrix.

+WebM recordings are **not** included in this drop (no automated MediaRecorder capture in CI/agent).
+
+Evidence substitutes:
+- Hardware GPU performance JSON (GTX 1080, profiles A–E)
+- Headless drop validation 7/7 × 10/10 with pusher contact
+- Still screenshots of mechanism / routes
+
+`runtime_visual_review: PARTIAL` until WebM is captured on a desktop session.
