Done

• nearcore:
  • Indexer Framework 0.9 release (refactor(indexer): Update Indexer Framework 0.9.0 (IndexerShard) #4245) received some love from @khorolets who introduced release notes (NEAR Indexer Framework 0.9.0 Release notes #4257), which helped Indexer Framework users to migrate through the breaking changes in no time ❤️
  • fixed corrupted archival testnet nodes (leftovers from testnet hard-reset) (@mhalambek 👍)
• indexer-for-explorer:
  • there were unplanned Indexer for Explorer downtimes on mainnet (due to protocol upgrade) and testnet (due to a bug in infrastructure automation process) which were addressed by @khorolets, @chefsale, and @frol ASAP 💪
  • Indexer for Explorer infrastructure provisioning is done (kudos to @chefsale!)
• balances:
  • the functional requirements for the lockup contract were collected in order to write the high-level documentation and confirm that the implementation is aligned (@telezhnaya and @frol drive the initiative 😎)
