Successfully reading TTree data:

  • arrays and jagged arrays
  • simpler Interpretation machinery (basket_array and finalized_array only), entry slicing still works
  • aliases and computable expressions
  • parallel multipart download → decompression pipeline
  • caching
  • backend libraries with library-dependent array grouping (dict of NumPy arrays, Awkward record array, Pandas DataFrame, etc.)

Not done:

  • all the Interpretation classes, particularly objects and strings
  • objects as record arrays
  • iteration (in a TTree or across files)
  • lazy arrays in Awkward
  • branch → multiple columns in Pandas (e.g. fixed-width arrays and leaf-lists)
  • extensive testing
