The relationship between Dapp, Fundraising and DAO Ops is definitely confusing - However this is not anything new and we had the same setup in our DAO Ops Season 1 proposal which was clearly stated on the proposal.
DAO Ops Working Group Proposal
That being said I have been pushing for someone to lead a Fundraising WG so that we can have a clear WG to attribute our time spent Fundraising for Giveth (or even perhaps the Galaxy). Until that WG is established unfortunately DAO Ops is the catch-all for those expenses.
If you have any future questions or uncertainties on how to allocate your hours we can definitely spend some time to sort them out.
To your other question, the budget for the buddy bot was about $600 - currently @Nicbals & @geleeroyale are still working on it, albeit at a slow pace.
We could estimate about 10 hours saved quarterly by having the automations offered by the buddy system bot, this includes sending buddy reminders, sending peer review forms to contributors, sending all the necessary reminders as well as sending the peer review data to a given buddy, ahead of their call.
The $4k difference will mostly come from not doing the DAO health check as well as not developing the plan to change the way we handle rGIV distributions.
