WalkthroughThe pull request centralizes room and room-update types, adds a reusable Zustand hook, and updates RoomView, MessageComposer, helper methods, ShareView, and related tests to use the shared contracts. ChangesRoom type consolidation

The remaining risk is limited to unresolved TypeScript convention deviations and does not indicate a user-facing behavioral failure.

9-10: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winPrefer an interface for
ComposerState.
ComposerStatedefines an object shape with a type alias and an intersection. Define it asinterface ComposerState extends IRoomWithUpdateStateinstead. KeepTComposerExternalStateas the utility type alias.As per coding guidelines: Prefer interfaces over type aliases for defining object shapes in TypeScript.

Proposed changes
Move the room contract and the hook that observes in-place room updates into shared definitions and hooks. Composer, RoomView, and ShareView now use that contract, removing the composer’s dependency on RoomView and typing ShareView’s room honestly.
The implementation is commit
07aa0583ac(25 files). It preserves the existing subscribed-room and preview-room shapes and adds a regression test proving a new update patch re-renders consumers of the same room instance.Issue(s)
Stacked on #7657 (
