The full detail on every reeval feature, one topic per page. Parts of it (the CLI help, the `reeval query` views, the option keys, exit codes and the record's fields) are generated from the code, so they match the version you run.

```ts
import { defineConfig, evaluate, expect, group } from '{{ pkg }}'
import { cursor } from '{{ pkg }}/harness'
import { docker } from '{{ pkg }}/sandbox'
```
