Description
Enable application teams to evolve real-time interactions and user interfaces against shared types, constants, TypeScript rules, lint rules, and reusable UI components rather than duplicating incompatible definitions.
User or operator problem
Application teams risk incompatible real-time behavior and inconsistent interfaces when contracts, constants, and components are duplicated.
Expected value
Keeps client, service, and interface behavior aligned while reducing duplicated definitions.
Scope
Includes shared player, chat, voice, seat, authentication, control, socket, TypeScript, lint, and reusable UI foundations.
Exclusions
- End-user product behavior and solution or release authorization are outside these engineering Features.
Acceptance outcomes
- Frontend and backend consume the same player, chat, voice, seat, and authentication contracts.
- Common controls and socket event names have one shared definition.
- Reusable UI components can be developed, demonstrated, and tested independently.
Dependencies
Risks
- Shared contract changes can break multiple applications unless all consumers are validated together.
Human approval

Delivery status evidence
The Feature was separately registered at IN_BACKLOG as an accepted catalogue boundary. This records backlog retention, not design or delivery progress.
- Event: Catalogue registration
- Actor and authority: Linas — Human project team member
- Reason: The Feature catalogue was accepted for governed documentation and retained in the backlog.
- Status evidence
Architecture traceability
- Requirements: none derived.
- Readiness: Not started.
Architecture solution work must not begin until a separate human Approved for Solution decision is recorded.
