**Error** from the compiler, while it builds your `.tsrx` files.

## What happened

The start value of `state()` must be plain data. Another `state()` call is not data.

Markless prints the message, the reason, and a suggestion:

```text
MARKLESS_STATE_NESTED_CREATION: `<initSource>` declares graph state whose initial value is another state() call. `<name>` cannot store graph state as its value.
A graph cell serializes plain data across the resume boundary; a state() call declares a cell and has no serializable value form.
Before: `const x = state(state(5));` — After: `const x = state(5);`.
https://markless.dev/errors/MARKLESS_STATE_NESTED_CREATION
```

Words in angle brackets change from case to case.

## How to fix it

Pass the plain start value.

```tsrx
const x = state(5);
```
