Governor upgrade todos

Definitions:

• TemporaryGovernance - TemporaryGovernance.sol solidity contract used as temporary implementation for both Governance and Governor
• TGovernance - the old governance proxy contract with TemporaryGovernance implementation
• TGovernor - the new governor proxy contact with TemporaryGovernance implementation

phase 0: prep for ab actions

1. execute script to push old governance rewards
2. deploy registry implementation (create2) and proxy (create1) manually
3. transfer registry proxy ownership to AB safe multisig (to avoid deployer compromise risk)
4. deploy new contract implementations (create2)
   • TemporaryGovernance
   • LegacyAssessment
   • LegacyMemberRoles

phase 1: first ab actions

1. upgrade using old Governance proposal (upgrade multiple contracts):
   • upgrade Governance to TemporaryGovernance
   • upgrade Assessment to LegacyAssessment
   • upgrade MemberRoles to LegacyMemberRoles
2. batch transactions using safe multisig calling TGovernance:
   • upgrade NXMaster
   • NXMaster.transferOwnershipToRegistry
   • Registry.migrate (will also upgrade Governor to use TemporaryGovernance)

phase 2: prep for ab actions

1. execute script to push LegacyAssessment stake and rewards
2. call LegacyMemberRoles.migrateMembers
3. deploy non-proxy contracts (create2)
   • CoverNFTDescriptor
   • VotePower
   • StakingViewer
   • CoverBroker
4. deploy new proxy contract implementations (create2)

   • SafeTracker
   • Assessments
   • Claims

   • Cover
   • CoverProducts
   • LimitOrders
   • StakingProducts
   • Governor

phase 3 (second ab action) - all are TGovernor actions except master.migrate

   • master.migrate (copies assets/oracles/mcr and moves the funds!) [TGovernance action]
   • transfer Registry proxy ownership to Governor
2. safe transaction via TGovernor.execute
