Query: The Path to $0.01\%$ Theoretical Luminosity Precision for the FCC-ee   The current status of the theoretical precision for the Bhabha luminometry is
critically reviewed and pathways are outlined to the requirement targeted by
the FCC-ee precision studies. Various components of the pertinent error budget
are discussed in detail -- starting from the context of the LEP experiments,
through their current updates, up to prospects of their improvements for the
sake of the FCC-ee. It is argued that with an appropriate upgrade of the Monte
Carlo event generator BHLUMI and/or other similar MC programs calculating QED
effects in the low angle Bhabha process, the total theoretical error of
$0.01\%$ for the FCC-ee luminometry can be reached. A new study of the $Z$ and
$s$-channel $\gamma$ exchanges within the angular range of the FCC-ee
luminometer using the BHWIDE Monte Carlo was instrumental in obtaining the
above result. Possible ways of BHLUMI upgrade are also discussed.
