World Fields

Reference for the World concept: what a world is at the field and contract level.

What A World Is

Property	Description
Identity	A unique world id; sortable; non-recyclable
Authoring	Created by an admitted world creator
Persistence	Long-lived; world state survives session boundaries; world history is append-only
Composability	Interoperable with other worlds via the six platform primitives
Authority	Realm owns canonical world truth, world state, and world history

A world is not a level, a chat room, a campaign, or an app session. A world keeps evolving even when no participants are present.

Concept	What it answers	Owner contract
Truth	What is canonically true in this world, regardless of when it was written	`realm/kernel/truth-contract.md` (`R-TRUTH-*`)
World State	What the world looks like right now	`realm/kernel/world-state-contract.md` (`R-WSTATE-*`)
World History	How the world reached its current state	`realm/kernel/world-history-contract.md` (`R-WHIST-*`)

These three are not interchangeable. A surface that conflates them silently loses information.

Adjacent Realm Surfaces Owned As World Truth

Surface	Contract	Rule prefix
Chat	`realm/kernel/chat-contract.md`	`R-CHAT-*`
Social	`realm/kernel/social-contract.md`	`R-SOC-*`
Economy	`realm/kernel/economy-contract.md`	`R-ECON-*`
Asset	`realm/kernel/asset-contract.md`	`R-ASSET-*`
Transit	`realm/kernel/transit-contract.md`	`R-TRANSIT-*`
Binding	`realm/kernel/binding-contract.md`	`R-BIND-*`
Resource	`realm/kernel/resource-contract.md`	`R-RSRC-*`
Bundle	`realm/kernel/bundle-contract.md`	`R-BNDL-*`

OASIS

Property	Value
Status	The unique system main world; formally part of canonical truth
Ownership	Cannot be owned by any creator
Replaceability	Cannot be replaced by an app convention
Role	Default return point and sole transit hub between worlds

App-World Binding

A world can bind to at most one active extension-app at a time. Other apps may consume world data in render-only mode.

State	Meaning
`(new)`	World exists but no app is bound
`active`	One extension-app is bound and writing
`suspended`	Binding is paused; rebinding requires explicit re-admission
`revoked`	Binding is removed; world becomes available for new binding

Re-binding requires revoking first; binding is not silently transferred.

App Modes

Mode	Read	Write	Concurrent count per world
`render-app`	yes	no	many
`extension-app`	yes	yes	at most one active

Six-Primitive Cross-Consistency

A world transition that involves multiple primitives must satisfy all relevant primitive contracts simultaneously:

A transit must satisfy Social + Economy + Context simultaneously.
Presence can't bypass social admission.
Timeflow cannot break economy settlement windows.

The six primitives are not independent enums; they are mutually constraining.

World Evolution Engine (Runtime-Owned)

When a world runs inside Runtime (Runtime-hosted world experiences), the World Evolution Engine governs its evolution. WEE has its own execution stage taxonomy distinct from Workflow:

INGRESS → NORMALIZE → SCHEDULE → DISPATCH → TRANSITION → EFFECT → COMMIT_REQUEST → CHECKPOINT → TERMINAL

Replay is recorded-only: WEE V1 replays from recorded events, checkpoints, and commit-request outcomes. There is no re-inference and no fresh route selection during replay.

Field	Owner
WEE event semantics	`runtime/kernel/world-evolution-engine-contract.md` (`K-WEV-*`)
Workflow partial-reuse hardcut	`runtime/kernel/world-evolution-engine-contract.md`
