Context#
V5 spans online co-op, PvP, companion app surfaces, and long-running campaign state. Players need account continuity without making single-player dependent on online service uptime.
Decision#
Crossplay and cross-progression are default V5 product requirements. Profile, cosmetics, Bureau XP, and Mind Palace state sync across linked platforms, while offline campaign paths remain playable and reconcile when services return.
Consequences#
- Save and profile systems must define conflict resolution.
- Single-player deterministic paths cannot depend on network output.
- Sci-Fi spaceship PvP can expose platform opt-out where input parity matters.
