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

## What happened

This `computed()` reads the value that it defines. There is no order in which Markless can work it out.

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

```text
MARKLESS_COMPUTED_DEPENDENCY_CYCLE: `<initSource>` reads `<name>` — the value it is defining. `<name>` cannot be derived from `<name>`.
A derive is a pull-based graph node; a cycle in its dependencies means there is no order in which the graph can produce the value.
Reference the source binding you meant to derive from, or rename one of the two values if this was a shadowing typo.

```

Words in angle brackets change from case to case.

## How to fix it

Read the value you meant to start from. If two values share a name by mistake, rename one.

## Where it comes from

`@markless/compiler` raises this code. Source:

- [packages/compiler/src/passes/semantic-graph/diagnostics.ts](https://github.com/compiled-run/markless/blob/main/packages/compiler/src/passes/semantic-graph/diagnostics.ts)
