Engineering notes (canonical)
Companion to README.md and /documentation. Not a stage changelog.
Coordinate conventions
- World units: 1 unit = 1 meter.
- Belt travel primarily along +X; belt top Y ≈ 0.70 m.
- Lateral: +Z = physical LEFT (category C), −Z = physical RIGHT (category D).
- Sorter CAD module origin X =
0; camera module−2.01; clean module−4.02. - Longitudinal plane S for diverter timing is world X along the sorter module.

Physics roadmap (not completed)
- Surface-velocity belt at 1 m/s with visual loop.
- Contact-validated CAD diverter deflection for all playlist SKUs.
- Calibrated per-SKU mass, COM, friction, damping.
- Receiver capture verification under dynamic drops.
CCD for light/thin items exists in runtime/sim; that alone is not full contact validation.
Compliance evidence rules
- Prefer present official files under
input_info/andofficial_sources/doc-1783095831.pdf. - Missing:
input_info/extracted/Постановка_Задача_3_сжато_2.pdf— never claim it is available. - Internal engineering criteria are not automatic Ozon pass/fail.
