B2OC: merge request for the next round of fixes (!4919) · Merge requests · LHCb / Moore

from Miroslav

Next opportunity to modify HLT2 selection for 2025 data taking is during June TS. 
Announced RTA deadline for code changes is 19/06 meaning internal [BnoC/]B2OC deadline 
is set to 12/06. All developments must target [`bnoc_run3`/]`b2oc-2025-dev` branch, for 
which MR already exist [1].

Please be aware the bandwidth situation which is still tight. Latest results based on 
early 2025 data can be found at [2].
New lines can be added based on the assumption of bandwidth being saved somewhere else.
