static constexpr int MaxLayers = static_cast<int>(o2::itsmft::tracking::MaxLayoutSurfaces)
 

Detailed Description

Row/column LUT helper. Charts have periodic phi rows and a descriptor-bounded linear column. MaxLayoutSurfaces storage keeps GPUhdi() access device-portable; callers must not query unpopulated runtime-plan positions.

Row origin/span, needed alongside the other getters to detect a configuration mismatch between a freshly bound IndexTableUtils and one already owned by a TimeFrame (LUT-reuse invariant); not test-only.

Configure LUT geometry with a row interval and per-surface column intervals. layerColHalfExtent may be shorter than MaxLayers (the common case – real detectors have far fewer than 32 layers); anything beyond its size is left at its previous value, exactly as it would be untouched by a caller that never re-populates it.
