+/// \file EventSelectionFlagsMapping.def
+/// \brief X-macro mapping between EventSelectionFlags and collisionCutsGroup
+///
+/// This file defines the canonical mapping between o2::aod::evsel::EventSelectionFlags
+/// enum values and collisionCutsGroup boolean member variables. It is used via X-macros
+/// to auto-generate member declarations, getters, setters, initialization, and metadata.
+///
+/// IMPORTANT: This file should NOT have include guards as it is included multiple times
+/// with different EVSEL_FLAG macro definitions.
+///
+/// Format: EVSEL_FLAG(enumValue, memberName, defaultValue, evtSelEnum, setterName, getterName, label, description)
+///
+/// Parameters:
+///   enumValue    - EventSelectionFlags enum (e.g., kIsTriggerTVX)
+///   memberName   - collisionCutsGroup bool member variable name
+///   defaultValue - Default value (true/false) in constructor
+///   evtSelEnum   - CollisonCuts::EvtSel enum value for histogram binning
+///   setterName   - CollisonCuts setter method name
+///   getterName   - collisionCutsGroup getter method name suffix (without 'get')
+///   label        - Histogram axis label (short, no spaces)
+///   description  - Human-readable description
+///
+/// To add a new event selection flag:
+/// 1. Add a new EVSEL_FLAG line below following the format
+/// 2. Ensure the EvtSel enum in collisionCuts.h has corresponding entry
+/// 3. Ensure the setter method exists in CollisonCuts class
+/// 4. Rebuild - all getters, members, logging, and metadata are auto-generated
+///
