# Review layout candidates

### Overview

Once Quilter has finished exploring layout options for a job, it marks it as "complete" and returns one of three different "results."

1. <mark style="background-color:green;">**Successful**</mark>**:** Quilter successfully identified >95% complete candidates.
2. <mark style="background-color:orange;">**Unsuccessful**</mark>**:** Quilter couldn't find any >95% complete candidates.
3. <mark style="background-color:red;">**Failed**</mark>**:** Quilter encountered an internal error or issue during the layout job and couldn't return *any* layout candidates.

On the Candidate Review page, you can:

* **Select candidates** by clicking them in the left-hand sidebar.
* **Inspect candidates** by clicking "Detail View" to toggle individual board layers and object types (see [Detail view](/candidate-review/detail-view.md)).
* **Review PRCs** for the selected candidate (see [Physics Rule Checks (PRCs)](/physics-rule-checks-prcs/overview.md)).
* **Download a placement** to modify the component locations, before reuploading it
* **Download a candidate** to inspect it offline in your preferred CAD tool and tweak the routing, or do a partial ripup before reuploading for Quilter to finish
* **Duplicate the job** to create a new draft layout job with the same files, physics constraints, and design parameters (see [Job Actions](/job-actions.md)).

{% hint style="danger" %}
**No candidates returned**
{% endhint %}

* If Quilter was entirely unable to return any layout candidates for your job, you will see the notification below.
* This usually means that Quilter encountered an error or issue while generating your layout job and failed to complete it.
* Clicking the "Send us a message" button will start a chat with the Quilter team so we can resolve the issue for you.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.quilter.ai/using-quilter/review-layout-candidates.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
