The time for stable module api is coming! With v0.52 almost (internally) audited and ready for alpha, we need to make sure cosmossdk.io/core v1 has good APIs.

From our call (1/2) we should change a few things before the alpha:

• store:
  • Add documentation that TransientStoreService isn't supported for store/v2 (refactor(core): core review (1/n) #21193)
  • Use core/store.StoreUpgrade in x/upgrade (@tac0turtle refactor: use corestore.StoreUpgrades #21259)
  • Remove NonConsensusStore until implemented (refactor(core): core review (1/n) #21193)
  • Check if Changeset / KVPairs should remain in core/store (@tac0turtle)
  • Move some interfaces from core/store to core/server (@julienrbrt): not moved, but added docs
• router
  • Remove InvokeTyped from router.Service and rename InvokeUntyped to invoke. Update the usage in module code (@julienrbrt) (refactor(core,stf,x)!: remove InvokeTyped from router #21224)
• app
  • Change type requirement BlockRequest (https://github.com/cosmos/cosmos-sdk/blob/main/core/app/app.go#L29-L30)
  • Check if ConsensusMessages still needed there (@tac0turtle) (refactor: remove consensus messages #21248)
  • Determine if events should be improved ([Feature]: Consider using schema/appdata event model in core/app #21312)
  • Determine if core/app should be moved back to server/v2 (not as its core modules but directly next to their implementation), if not moved, possibly rename it instead (@tac0turtle) (chore: cleanup core/app #21368)
  • Add doc.go (chore: cleanup core/app #21368)
• legacy
  • Rename legacy package to something more obvious. Additionally, think of putting all legacy interfaces in one package. (refactor(core): move amino registrar and drop legacy package #21531)
• attempt at 0 dependency for core (remove gogoproto) (ref refactor: zerodep core  #21239)
  • Refactor handlers to not require gogoproto.MessageName - router should get the name (@julienrbrt) (refactor(core): re-add handlers #21575)
• documentation
  • Add function and package documentation on every public function of core (@julienrbrt, @kocubinski, @tac0turtle) (docs(core): add core documentation and principles #21511)
  • Add core principles in README.md (docs(core): add core documentation and principles #21511)

In our next meeting (2/2), we'll finish reviewing core/store, core/testing and core/transaction. DONE.
Upon closing this issue, we can tag cosmossdk.io/core v1-alpha.1 (final v1 after 0.52 audit)
