- Rewrite the QC task as two ordering variants exposing the cumulative
inefficiency through the analysis selection cascade:
- processCrossSectionEfficiency (default): reco-collision-first
(cascade = sel-bits via reco-coll EvSel bitmask, then NoSplit + zReco).
- processCrossSectionEfficiencyBcBitsFirst: alternative ordering with
sel-bits read from the truth BC (Preslice on JBCs) and reco-coll
evaluated last; for systematic check.
- Cascade auto-adapts to {selTVX, selMC, selMCFull, sel8, sel8Full}; steps
not in the preset pass through so bin count/order stays constant.
- Skips min-bias gap events via getSubGeneratorId() == mbGap when
skipMBGapEvents = true (hybrid MB+JJ MC productions).
- Unified weighted/unweighted fills via mccollision.weight() (= 1 for MB).
- Outlier rejection via pTHat (stored ptHard, or weight-derived for legacy
cases) gated by pTHatMaxMCP; named broken-sentinel constant.
- Restores all upstream-side Configurables (centrality*, trackOccupancy*,
selectedJetsRadius, checkCentFT0M) for backward compatibility, even
when unused on the pp MB MC nominal path.
- applyRCT toggles the RCT step independently; preset label is a
Configurable.

- Follow naming conventions.
- Why is this not an
enum?

Why do you create a new variable?
