Create, review, run, and troubleshoot modern LHCb Run 3 DaVinci jobs using an options function, YAML data options, PyConf, and lbexec. Use for minimal DaVinci configurations, input-process and conditions setup, line filters, dry runs, and job artifact checks. Do not use for Run 1/2 gaudirun.py or configurable-style jobs, FunTuple variable design alone, data discovery, or grid production submission.

Design, review, and verify modern LHCb Run 3 FunTuple configurations and ROOT ntuple outputs. Use for decay fields, caret placement, ThOr functors, FunctorCollection composition, event variables, tuple naming, branch checks, and output inspection. Do not use for legacy DecayTreeTuple or LoKi TupleTools, general DaVinci environment setup, data discovery, or physics-variable choices without user requirements.

Select, construct, and verify a current LHCb Run 3 released or development software environment. Use for lb-run, lbexec, lb-dev, platform selection, DaVinci version selection, CVMFS availability, or diagnosing an LHCb application environment. Do not use for generic Python environments or legacy Run 1/2 setup unless the user explicitly requests legacy support.
