Iteration Visual QA Report

Date: 2026-07-09 Branch: dan_branch Scope: one limited 3D demo improvement cycle for https://arhipovdan.ru/.

Before / After Screenshots

Screenshots saved in docs/visual_qa_screenshots/:

• before_initial_production.png — production initial state before playback.
• after_running_item_on_belt.png — production after deploy, item moving on belt.
• after_cv_overlay_no_overlap.png — production after deploy, CV overlay visible without HUD overlap.
• after_demo_complete_8_cases.png — production after deploy, all 8 cases completed.
• after_details_page.png — /details production check.

Top 3 Issues Fixed

1. Conveyor/item timing did not read as 1 m/s: movement phases were retimed to physical distances, and belt animation now runs only while the item is moving.
2. Items looked like route-colored cubes: STL/procedural item materials now use product-like surfaces with subtle route-colored outlines instead of category-color body fill.
3. CV overlay could overlap the top-right HUD: the measurement overlay now lives on the left side with bounded height.

Verification

• npm run build — passed.
• npm run test — passed, 11 test files / 113 tests.
• docker compose -p owl -f docker-compose.server.yml up -d --build — passed, owl-web-1 recreated and started.
• Playwright production QA — passed with NO_CONSOLE_ERRORS.

Acceptance Checklist

• No console errors.
• Item does not fly.
• Item does not fall through the belt.
• STL/procedural items are visible and no longer read as route-colored cubes.
• Belt and item movement are synchronized during movement phases.
• HUD and CV overlay do not overlap.
• Play starts the demo.
• /details works.
• Before/after screenshots exist.

Notes

• No changes were made to /details, nginx, Dockerfile, classifier logic, or scenarios.
• No physics engine was added.
• No commit or push was made.
