## Finding

The synthesis and short guide have valid rectangular tables, working visual/document links, and complete section structure.

## Reassessment

Verify the completed prefix and unchanged source bindings before the closing record.

## Checks

```json
{
  "links": true,
  "tables": true
}
```
