Pass primitive state.
Initialize children directly.
Specialized children can initialize local state from one direct primitive parent prop. Kudzu reads the build-known value while preserving independent child ownership and the parent signal relationship.
1Direct primitive prop
2Independent state IDs
0 BBrowser runtime added
P1Read the build value.
PROP DATAFLOW
Read the build value.
Keep structural ownership.
Require primitive input
The compiler verifies the parent state has a build-known string, number, boolean, null, or undefined initializer.
Store JSON-safe data
Build scratch reads the parent signal value so RouteIR receives a serializable child initial value.
Keep states independent
Parent and child retain separate IDs while handlers and effects preserve structural prop links.
Reject wider shapes
Object/array props, aliases, composed expressions, and arbitrary initializers remain source-diagnosed.
Ship existing capabilities
No component runtime, hydration, state library, or browser module is added.
UPGRADE
Keep controlled child initialization ordinary.
