# OpenSpec Change: enterprise-gaming-party

- **Change ID**: enterprise-gaming-party
- **Package**: `@suaveplan/party`
- **Category**: gaming/multiplayer
- **Target path**: `gaming/multiplayer/party`
- **Status**: PROPOSED
- **Date**: 2026-04-24
- **Reference spec**: `/mnt/s/web/suaveplan/enterprise/party.md`

## Summary

Deliver `@suaveplan/party` on the genesis branch from scratch at enterprise quality. The package provides a party/group system with invites, leadership transfer, and kick/promote mechanics. A `PartyManager` creates/destroys `Party` objects; a `Party` tracks members with role (leader/officer/member), handles invite expiry, and enforces `maxSize`. An `InviteTracker` manages pending invites with configurable TTL and accept/decline/expire lifecycle. Genesis adds Zod schemas, structured errors, OTel active-party gauge, injectable clock, and 100% coverage.

## Impact

**Downstream**: `@suaveplan/react-social-game` shows party panel; `@suaveplan/lobby` transfers party to lobby. Prerequisites: `@suaveplan/error`, `@suaveplan/types`, `@suaveplan/events`.
