Vault and dripper are generated from POOL4's StakedIMD and RewardDripper by upstream/make_staking.py with changes: limited, expiring owner powers (pause <= 3 days, no rescue of stake or reward buffer, all powers end at powersExpireAt) and a self-adjusting drip (buffer x elapsed / smoothing period).
