Yes, at the moment its all vaults. We are confirming churn testing, The Immutable Data manager is currently undergoing surgery. It was very highly coupled and currently being modularised a lot internally.
MaidManger SDManager etc. were all updated this week and testing yesterday well enough. ImmutbaleData manager though was very difficult to work through sensibly, so this is an area we are working on now. Never thought it was so coupled, but it is and that needs fixed. A few hours ago I took my local branch and started big changes. Scary though at this point to do this so quickly, but voults now are really very simple code (or should be). So yesterday was tough and today will need a lot of focus.
PmidManager and PmidNode will be very simple though, we already know what they need for churn (Answer is same as MaidManager and nothing respectively). So we are OK there.
So coming over the line, but having to get a lot of last minute energy to do so. We will get this asap, but not huge as I say, this part of the code we control, unlike much lower areas such as crust. So we are good in that respect.
