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

## What happened

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

```text
MARKLESS_STATE_HELPER_RETURN_UNSUPPORTED: <apiName>() creates "<name>" inside a helper function, but the compiler cannot connect this helper return shape to the component graph binding.
The compiler supports same-module direct helper returns and compiled imported helpers. This gate remains for residual helper shapes such as object returns, nested return chains, or imported helpers without module graph interface data.
Return the graph binding directly from the helper, compile the imported helper with interface output, or declare the state in the component body.

Words in angle brackets change from case to case.

## How to fix it
