juhofer (DESY) will work in the context of release 22 software development for Run3. She will start by updating and extending the flavour tagging validation software to cover the latest b-taggers in release 22. Both basic reconstructed quantities as well as high-level tagger performance should be included in the validation tests. These will be used to cross-validate release 21 results with those obtained in release 22, in view of the feature freeze foreseen for Summer 2020. In this process, Judith will become familiar with the development of flavour tagging software and its configuration; particular emphasis will be put on the development of track-based taggers, a key ingredient of the commissioning strategy for Run 3. All new developments will be documented on GitLab or on the flavour tagging TWiki, facilitating future validation campaigns.
