I'm happy to, have you made sure any open reviews for those branches
are abandoned first? Gerrit won't allow deletion of a branch with
open reviews.

The Gerrit REST API method for deleting branches is documented here:


I'm not immediately sure where branch creation happens in the forest
of our release automation, but I would expect deletion could be
implemented similarly. Hopefully someone more intimately familiar
with those jobs can chime in.

The access control we'll need to grant to automation so that it can
call that is documented here:


It'll need to be added manually as a permission for the Release
Managers group in our All-Projects global ACL which individual
projects inherit, and this documentation updated accordingly:


Happy to answer other questions as they arise.
