Multiplayer#
Population bands#
| Concurrent population | Runtime behavior |
|---|---|
| 1 | full solo path; family Actors/Ally support; asynchronous human offers |
| 2–8 | shared table/quest instance; direct portrait presence |
| 9–32 | Area-local voice/text; nearby individual presence; scoped group Actions |
| 33–256 | Scene shards share canonical world version; public events replicated; private interaction local |
| 257–5,000 | Area shards, presence constellations, scheduled gatherings, event-stream summaries |
| 5,000+ | regional/cohort shards; shared milestones and Portal topology; sampled crowd rendering; no global chat |
Canonical Actor, Project, Portal, and island changes use versioned events and conflict-safe Commands. Presence and ambient motion are not canonical. A player enters a shard with friends/project collaborators when authorized, otherwise the least-loaded compatible shard. Moving shards preserves Source/Avatar identity and returns focus to the same landmark.
Social safety#
Proximity does not grant messaging. Requests carry identity, purpose, context, and easy decline. Block/mute separates presence and communication without implying the blocked person disappeared from shared world truth where that would be misleading. Moderation Actions are typed, appealable, and privacy scoped.
