> The OST flows today run on package repos that are composed wither from all available updates (As in the case of the 'experimental' flows) or on manually curated repos (As in the case of the 'older' OST flows or the manual flows).
> The existing flows lack feedback. When OST fails it can be hard to know which of the group of changes that happened before it ran was the one to cause to to fail. This places a severe workload on the infra team to diagnose and report OST failures.
> This ticket suggest the creation of a new flow where all changes to all OST input sources are tracked, so that when OST fails it is possible to run a bisection algorithm and automatically report to the developers about the change that caused the failure.
> This approach can more cheaply provide most of the benefits of pre-merge gating while side-stepping some of the technical complications.
