Body

application/json

A node in the graph. Optional fields beyond those listed are allowed (forward-compatible). Prose fields must describe pixels, not intent. The kernel doctrine lints enforce this on every write.

base
string

Scene prose for this node (pixels, not intent).

camera
object

A static/dynamic prompt pair. The world model is conditioned on the static layer while the scene holds and on the dynamic layer while it moves. Both are pixel-prose, never authorial intent.

movement
object

A static/dynamic prompt pair. The world model is conditioned on the static layer while the scene holds and on the dynamic layer while it moves. Both are pixel-prose, never authorial intent.

ambient
string[]

Ambient detail prose fragments.

ending
object

Marks this node as a TERMINAL sink. A node with an ending must be a dead end (no outgoing transitions).

variants
object[]

A/B prompt arms (play-only; never compiled into the graph).

Response

State updated

The result of a graph write. world is the new, kernel-validated world; diagnostics carries advisory (warning/info) findings; rev is the new concurrency token (also returned as the ETag header).

world
object

A playable world's compiled graph, id, name, entrance, and the scene (states + events). This is the shape returned inside the world field of a World resource (see World) and by the graph-editing routes. Additional optional properties are allowed (forward-compatible); the schemaVersion on responses pins the contract version.

diagnostics
object[]
rev
string

The new revision token. Pass it as If-Match on the next write.

schemaVersion
string
Example:

"1.0"
